GTK+ requires the following packages:
- - The GLib, Pango, ATK and cairo libraries, available at the same
- location as GTK+. GTK+ @GTK_VERSION@ requires at least GLib 2.23.6,
- Pango 1.20, ATK 1.29.2 and cairo 1.6.0.
+ - The GLib, Pango, GdkPixbuf, ATK and cairo libraries, available at
+ the same location as GTK+. GTK+ @GTK_VERSION@ requires at least
+ GLib 2.23.6, Pango 1.20, GdkPixbuf 2.21.0 ATK 1.29.2 and cairo 1.6.0.
- gobject-introspection 0.6.7 or newer.
- - The TIFF, PNG, and JPEG image loading libraries. You most
- likely have these installed on your system already. If not
- these libraries are available from:
-
- http://www.libtiff.org/
- http://www.libpng.org/
- http://www.ijg.org/
-
- libtiff must be version 3.6.0 or higher.

-
- Work to create an Xlib version of gdk-pixbuf (with the Xlib
- port of GdkRGB for rendering):
-
- * configure.in: check for X libraries, set and substitute
- GDK_PIXBUF_XLIB_{LIBDIR,INCLUDEDIR,LIBS} variables
-
- * gdk_pixbuf_xlibConf.sh.in: new file -- gnome-config details
- for the gdk-pixbuf-xlib library
- * Makefile.am: build and install gdk_pixbuf_xlibConf.sh
-
- * gdk-pixbuf/gdk-pixbuf-xlib-render.c,
- gdk-pixbuf/gdk-pixbuf-xlib.c, gdk-pixbuf/gdk-pixbuf-xlib.h,
- gdk-pixbuf/gdk-pixbuf-xlib-private.h,
- gdk-pixbuf/gdk-pixbuf-xlib-drawable.c: new files, ported the
- GDK dependent parts of gdk-pixbuf to use Xlib. Functions that
- were called gdk_pixbuf_FOO are now gdk_pixbuf_xlib_FOO
-
- * gdk-pixbuf/gdk-pixbuf-xlibrgb.c,
- gdk-pixbuf/gdk-pixbuf-xlibrgb.h: added Chris Blizzard's Xlib
- port of GdkRGB (from Mozilla CVS)
-
- * gdk-pixbuf/Makefile.am: build a library libgdk_pixbuf_xlib.la
- including the non-GDK dependent objects from libgdk_pixbuf.la
- plus the Xlib ports and xlibrgb

- * be ignored.
- * @visual: A visual if @src is a pixmap. If it is a window, this argument will
- * be ignored.
- * @src_x: Source X coordinate within drawable.
- * @src_y: Source Y coordinate within drawable.
- * @dest_x: Destination X coordinate in pixbuf, or 0 if @dest is NULL.
- * @dest_y: Destination Y coordinate in pixbuf, or 0 if @dest is NULL.
- * @width: Width in pixels of region to get.
- * @height: Height in pixels of region to get.
- *
- * Transfers image data from a Gdk drawable and converts it to an RGB(A)
- * representation inside a GdkPixbuf.
- *
- * If the drawable @src is a pixmap, then a suitable colormap must be specified,
- * since pixmaps are just blocks of pixel data without an associated colormap.
- * If the drawable is a window, the @cmap argument will be ignored and the
- * window's own colormap will be used instead.
- *
- * If the specified destination pixbuf @dest is #NULL, then this function will
- * create an RGB pixbuf with 8 bits per channel and no alpha, with the same size
- * specified by the @width and @height arguments. In this case, the @dest_x and
- * @dest_y arguments must be specified as 0, otherwise the function will return
- * #NULL. If the specified destination pixbuf is not NULL and it contains alpha
- * information, then the filled pixels will be set to full opacity.
- *
- * If the specified drawable is a pixmap, then the requested source rectangle
- * must be completely contained within the pixmap, otherwise the function will
- * return #NULL.
- *
- * If the specified drawable is a window, then it must be viewable, i.e. all of
- * its ancestors up to the root window must be mapped. Also, the specified
- * source rectangle must be completely contained within the window and within
- * the screen. If regions of the window are obscured by noninferior windows, the
- * contents of those regions are undefined. The contents of regions obscured by
- * inferior windows of a different depth than that of the source window will also
- * be undefined.
- *
- * Return value: The same pixbuf as @dest if it was non-NULL, or a newly-created
- * pixbuf with a reference count of 1 if no destination pixbuf was specified; in
- * the latter case, NULL will be returned if not enough memory could be
- * allocated for the pixbuf to be created.

- 1. Shifting instead of lookup tables (less memory traffic).
-
- 2. Much less register pressure, especially because shifts are
- in the code.
-
- 3. A memcpy is avoided (i.e. the transfer function).
-
- 4. On big-endian architectures, byte swapping is avoided.
-
- That said, it wouldn't be hard to make it even faster - just make an
- inner loop that reads 3 words (i.e. 4 24-bit pixels), does a lot of
- shifting and masking, then writes 2 words.

- <!-- Introduction -->
-
- <sect1>
- <title>Introduction</title>
-
- <para>
- Prior to the GNOME 1.2 platform, the &Imlib; library was the
- preferred way of loading and rendering images in GNOME
- applications. Unfortunately, &Imlib; has important design
- limitations that make it hard to write efficient and highly
- modular applications.
- </para>
-
- <para>
- The &gdk-pixbuf; library was designed as a solution to
- &Imlib;'s shortcomings. It provides a simple, orthogonal API
- and convenience functions for the most common operations. In
- addition, it supports full transparency information for
- images, or alpha channel. More importantly, it has
- well-defined semantics for memory management through the use
- of reference counting; &Imlib; has an intractably complex
- memory management mechanism and cache that will make your head
- spin.
- </para>
- </sect1>
-
- <!-- Differences between Imlib and gdk-pixbuf -->
-
- <sect1>
- <title>Differences between &Imlib; and &gdk-pixbuf;</title>
-
- <para>
- Generally, applications that use &Imlib; do not have to be
- changed extensively to use &gdk-pixbuf;; its simple and
- flexible API makes things easy. This section describes the
- differences between &Imlib; and &gdk-pixbuf;; you should take
- these into account when modifying your applications to use
- &gdk-pixbuf;.
- </para>
-
- <!-- Initialization -->
-
- <sect2>
- <title>Initialization</title>
-
- <para>
- The &gdk-pixbuf; library does not need to be initialized.
- </para>
-
- <note>
- <para>
- In GNOME applications you normally don't need to
- initialize &Imlib;, as <function>gnome_init()</function>
- calls <function>gdk_imlib_init()</function> automatically.
- </para>
- </note>
- </sect2>
-
- <!-- Memory management -->
-
- <sect2>
- <title>Memory management</title>
-
- <para>
- The &gdk-pixbuf; library provides a simple, well-defined
- memory management mechanism for images in the form of
- reference counting. This makes it very convenient to use
- for large-scale applications that need to share images
- between different parts of the program. In stark contrast,
- &Imlib; has a terribly complex mechanism of an image and
- pixmap cache which makes it very hard for applications to
- share image structures between different parts of the
- program. Unfortunately this mechanism makes things very
- prone to memory leaks and tricky bugs.
- </para>
-
- <para>
- The basic principle in &gdk-pixbuf; is that when you obtain
- a new <link linkend="GdkPixbuf">GdkPixbuf</link> structure,
- it is created with an initial reference count of 1. When
- another part of the program wants to keep a reference to the
- pixbuf, it should call <function>g_object_ref()</function>;
- this will increase the reference count by 1. When some part
- of the program does not need to keep a reference to a pixbuf
- anymore and wants to release the pixbuf, it should call
- <function>g_object_unref()</function>; this will decrease
- the reference count by 1. When the reference count drops to
- zero, the pixbuf gets destroyed or
- <emphasis>finalized</emphasis> and its memory is freed.
- </para>
-
- <para>
- For applications that need to implement a cache of loaded
- images, &gdk-pixbuf; provides a way to hook to the last
- unreference operation of a pixbuf; instead of finalizing the
- pixbuf, the user-installed hook can decide to keep it around
- in a cache instead.
- </para>
-
- <para>
- Finally, &gdk-pixbuf; does not provide a cache of rendered
- pixmaps. This is unnecessary for most applications, since
- the scaling and rendering functions are quite fast and
- applications may need to use subtly different values each
- time they call these functions, for example, to take into
- account dithering and zooming offsets.
- </para>
-
- <para>
- Most applications will simply need to call
- <function>g_object_ref()</function> when they want to keep
- an extra reference to a pixbuf, and then
- <function>g_object_unref()</function> when they are done
- with it.
- </para>
- </sect2>
-
- <!-- The Rendering Process -->
-
- <sect2>
- <title>The Rendering Process</title>
-
- <para>
- The &gdk-pixbuf; library has the policy of always rendering
- pixbufs to GDK drawables you provide; it will not create
- them for you. This is in general more flexible than
- &Imlib;'s policy of always creating a pixmap and making you
- use that instead.
- </para>
-
- <para>
- The disadvantage of always having a pixmap created for you
- is that it wastes memory in the X server if you intend to
- copy that rendered data onto another drawable, for example,
- the final destination window or a temporary pixmap for
- drawing. This is the most common case, unfortunately, so
- the &Imlib; policy introduces unnecessary copying.
- </para>
-
- <para>
- Also, &Imlib; can only render pixmaps that are the whole
- size of the source image; you cannot render just a subset
- region of the image. This is inconvenient for applications
- that need to render small portions at a time, such as
- applications that do scrolling. Since the whole image must
- be rendered at a time, this can lead to performance and
- memory usage problems.
- </para>
-
- <para>
- The &gdk-pixbuf; library lets you render any rectangular
- region from an image onto any drawable that you provide.
- This lets the application have fine control the way images
- are rendered.
- </para>
- </sect2>

- <!-- Converting Applications to gdk-pixbuf -->
-
- <sect1>
- <title>Converting Applications to &gdk-pixbuf;</title>
-
- <para>
- This sections describes the actual changes you need to make in
- an &Imlib; program to make it use &gdk-pixbuf; instead.
- </para>
-
- <!-- Image loading and creation -->
-
- <sect2>
- <title>Image loading and creation</title>
-
- <para>
- The &gdk-pixbuf; library can load image files synchronously
- (i.e. with a single function call), create images from RGB
- data in memory, and as a convenience, it can also create
- images from inline XPM data.
- </para>
-
- <para>
- To load an image file in a single function call, simply use
- <function>gdk_pixbuf_new_from_file()</function>. Note that
- this will make the program block until the whole file has
- been read. This function effectively replaces
- <function>gdk_imlib_load_image()</function>.
- </para>
-
- <para>
- If you have RGB data in memory, you can use
- <function>gdk_pixbuf_new_from_data()</function> to create a
- pixbuf out of it; this is a replacement for
- <function>gdk_imlib_create_image_from_data()</function>.
- &gdk-pixbuf; does not copy the image data; it is up to you
- to define the ownership policy by providing a destroy
- notification function that will be called when the image
- data needs to be freed. The function you provide can then
- free the data or do something else, as appropriate.
- </para>
-
- <para>
- As a convenience, you can use the
- <function>gdk_pixbuf_new_from_xpm_data()</function> function
- to create a pixbuf out of inline XPM data that was compiled
- into your C program. This is a replacement for
- <function>gdk_imlib_create_image_from_xpm_data()</function>.
- </para>
-
- <para>
- After you have created a pixbuf, you can manipulate it in
- any way you please and then finally call
- <function>g_object_unref()</function> when you are done
- with it. This can be thought of as a replacement for
- <function>gdk_imlib_destroy_image()</function> but with much
- cleaner semantics.
- </para>
- </sect2>
-
- <!-- Rendering Images -->
-
- <sect2>
- <title>Rendering Images</title>
-
- <para>
- Applications that use &Imlib; must first call
- <function>gdk_imlib_render()</function> to render the whole
- image data onto a pixmap that &Imlib; creates. Then they
- must copy that pixmap's data into the final destination for
- the image.
- </para>
-
- <para>
- In contrast, &gdk-pixbuf; provides convenience functions to
- render arbitrary rectangular regions of an image onto a
- drawable that your application provides. You can use
- <function>gdk_draw_pixbuf()</function> to do this; having
- your application provide the destination drawable and
- specify an arbitrary region means your application has
- complete control over the way images are rendered.
- </para>
-
- <para>
- As a convenience, &gdk-pixbuf; also provides the
- <function>gdk_pixbuf_render_pixmap_and_mask()</function>
- function; this will create new pixmap and mask drawables for
- a whole pixbuf and render the image data onto them. Only
- trivially simple applications should find a use for this
- function, since usually you want finer control of how things
- are rendered.
- </para>
- </sect2>
-
- <!-- Scaling Images -->
-
- <sect2>
- <title>Scaling Images</title>
-

- The &gdk-pixbuf; library provides a simple mechanism to load and represent
- animations. An animation is conceptually a series of frames to be displayed
- over time. Each frame is the same size. The animation may not be represented
- as a series of frames internally; for example, it may be stored as a
- sprite and instructions for moving the sprite around a background. To display
- an animation you don't need to understand its representation, however; you just
- ask &gdk-pixbuf; what should be displayed at a given point in time.

-Creating a pixbuf from image data that is already in memory.
-
-<!-- ##### SECTION Long_Description ##### -->
- <para>
- The most basic way to create a pixbuf is to wrap an existing pixel
- buffer with a #GdkPixbuf structure. You can use the
- gdk_pixbuf_new_from_data() function to do this You need to specify
- the destroy notification function that will be called when the
- data buffer needs to be freed; this will happen when a #GdkPixbuf
- is finalized by the reference counting functions If you have a
- chunk of static data compiled into your application, you can pass
- in %NULL as the destroy notification function so that the data
- will not be freed.
- </para>
-
- <para>
- The gdk_pixbuf_new() function can be used as a convenience to
- create a pixbuf with an empty buffer. This is equivalent to
- allocating a data buffer using <function>malloc()</function> and
- then wrapping it with gdk_pixbuf_new_from_data(). The gdk_pixbuf_new()
- function will compute an optimal rowstride so that rendering can be
- performed with an efficient algorithm.
- </para>
-
- <para>
- As a special case, you can use the gdk_pixbuf_new_from_xpm_data()
- function to create a pixbuf from inline XPM image data.
- </para>
-
- <para>
- You can also copy an existing pixbuf with the gdk_pixbuf_copy()
- function. This is not the same as just doing a g_object_ref()
- on the old pixbuf; the copy function will actually duplicate the
- pixel data in memory and create a new #GdkPixbuf structure for it.

- <para>
- #GdkPixbufLoader provides a way for applications to drive the
- process of loading an image, by letting them send the image data
- directly to the loader instead of having the loader read the data
- from a file. Applications can use this functionality instead of
- gdk_pixbuf_new_from_file() or gdk_pixbuf_animation_new_from_file()
- when they need to parse image data in
- small chunks. For example, it should be used when reading an
- image from a (potentially) slow network connection, or when
- loading an extremely large file.
- </para>
-
- <para>
- To use #GdkPixbufLoader to load an image, just create a new one,
- and call gdk_pixbuf_loader_write() to send the data to it. When
- done, gdk_pixbuf_loader_close() should be called to end the stream
- and finalize everything. The loader will emit three important
- signals throughout the process. The first, "<link
- linkend="GdkPixbufLoader-size-prepared">size_prepared</link>",
- will be called as soon as the image has enough information to
- determine the size of the image to be used. If you want to scale
- the image while loading it, you can call gdk_pixbuf_loader_set_size()
- in response to this signal.
- </para>
-
- <para>The second signal, "<link
- linkend="GdkPixbufLoader-area-prepared">area_prepared</link>",
- will be called as soon as the pixbuf of the desired has been
- allocated. You can obtain it by calling gdk_pixbuf_loader_get_pixbuf().
- If you want to use it, simply ref it.
- In addition, no actual information will be passed in yet, so the
- pixbuf can be safely filled with any temporary graphics (or an
- initial color) as needed. You can also call
- gdk_pixbuf_loader_get_pixbuf() later and get the same pixbuf.
- </para>
-
- <para>
- The last signal, "<link
- linkend="GdkPixbufLoader-area-updated">area_updated</link>" gets
- called every time a region is updated. This way you can update a
- partially completed image. Note that you do not know anything
- about the completeness of an image from the area updated. For
- example, in an interlaced image, you need to make several passes
- before the image is done loading.

- to get the #GdkPixbufAnimation struct and gdk_pixbuf_animation_get_iter()
- to get an #GdkPixbufAnimationIter for displaying it.

- <para>
- In addition to the normal affine transformations supported by
- canvas items, the #GnomeCanvasPixbuf item supports independent
- object arguments for scaling and translation. This is useful
- for explicitly setting a size to which the pixbuf's image will
- be scaled, and for specifying translation offsets that take
- place in the item's local coordinate system.
- </para>
-
- <para>
- By default, the pixbuf canvas item will attain the size in units
- of the #GdkPixbuf it contains. If a #GnomeCanvasPixbuf is
- configured to use a #GdkPixbuf that has a size of 300 by 200
- pixels, then the pixbuf item will automatically obtain a size of
- 300 by 200 units in the item's local coordinate system. If the
- item is transformed with a scaling transformation of (0.5, 2.0),
- then the final image size will be of 150 by 400 pixels.
- </para>

- To set custom width and height values, you must set the <link
- linkend="GnomeCanvasPixbuf--width-set">width_set</link> or <link

- arguments to %TRUE, and then set the <link
- linkend="GnomeCanvasPixbuf--width">width</link> or <link
- linkend="GnomeCanvasPixbuf--height">height</link> arguments to
- the desired values. The former two arguments control whether
- the latter two are used when computing the final image's size;
- they are both %FALSE by default so that the pixbuf item will
- attain a size in units equal to the size in pixels of the
- #GdkPixbuf that the item contains.
- </para>
-
- <para>
- The custom translation offsets are controlled by the <link
- linkend="GnomeCanvasPixbuf--x">x</link> and <link

- allows images to be translated and scaled by absolute pixel
- values that are independent of an item's normal affine
- transformation.
- </para>
-
- <para>
- Normally, the pixbuf item's translation and scaling arguments
- are interpreted in units, so they will be modified by the item's
- affine transformation. The <link

- object arguments can be used to modify this behavior. If one of
- these arguments is %TRUE, then the corresponding scaling or
- translation value will not be affected lengthwise by the pixbuf
- item's affine transformation.
- </para>
-
- <para>
- For example, consider a pixbuf item whose size is (300, 200).
- If the item is modified with a scaling transformation of (0.5,
- 2.0) but the <link
- linkend="GnomeCanvasPixbuf--width-in-pixels">width_in_pixels</link>
- is set to %TRUE, then the item will appear to be (300, 400)
- pixels in size. This means that in this case the item's affine
- transformation only applies to the height value, while the width
- value is kept in absolute pixels.
- </para>
-
- <para>
- Likewise, consider a pixbuf item whose (<link
- linkend="GnomeCanvasPixbuf--x">x</link>, <link
- linkend="GnomeCanvasPixbuf--y">y</link>) arguments are set to
- (30, 40). If the item is then modified by the same scaling
- transformation of (0.5, 2.0) but the <link
- linkend="GnomeCanvasPixbuf--y-in-pixels">y_in_pixels</link>
- argument is set to %TRUE, then the image's upper-left corner
- will appear to be at position (15, 40). In this case, the
- affine transformation is applied only to the x offset, while the
- y offset is kept in absolute pixels.
- </para>
-
- <para>
- In short, these arguments control whether a particular dimension
- of a pixbuf item is scaled or not in the normal way by the
- item's affine transformation.

- <para>
- When you set the #GdkPixbuf structure that a #GnomeCanvasPixbuf
- item will use by setting the <link
- linkend="GnomeCanvasPixbuf--pixbuf">pixbuf</link> argument, a
- reference count will be added to that #GdkPixbuf structure.
- When the pixbuf item no longer needs the #GdkPixbuf structure,
- such as when the item is destroyed or when a new pixbuf
- structure is passed to it, then the old #GdkPixbuf structure
- will be automatically unreferenced.
- </para>
-
- <para>
- This means that if an application just needs to load a pixbuf
- image and set it into a pixbuf canvas item, it can do the
- following to ‘forget’ about the pixbuf structure:
-
- <programlisting>
- GdkPixbuf *pixbuf;
- GnomeCanvasItem *item;
-
- pixbuf = gdk_pixbuf_new_from_file ("foo.png");
- g_assert (pixbuf != NULL);
-
- item = gnome_canvas_item_new (gnome_canvas_root (my_canvas),
- gnome_canvas_pixbuf_get_type (),
- "pixbuf", pixbuf,
- NULL);
- gdk_pixbuf_unref (pixbuf);
- </programlisting>
- </para>
-
- <para>
- After this happens, the reference count of the pixbuf structure
- will be 1: the gdk_pixbuf_new_from_file() function creates it
- with a reference count of 1, then setting the <link
- linkend="GnomeCanvasPixbuf--pixbuf">pixbuf</link> argument of
- the #GnomeCanvasPixbuf item increases it to 2, and then it is
- decremented to 1 by the call to gdk_pixbuf_unref(). When the
- canvas item is destroyed, it will automatically unreference the
- pixbuf structure again, causing its reference count to drop to
- zero and thus be freed.

- Image data in a pixbuf is stored in memory in uncompressed,
- packed format. Rows in the image are stored top to bottom, and
- in each row pixels are stored from left to right. There may be
- padding at the end of a row. The "rowstride" value of a pixbuf,

- of bytes between rows.

- The following code illustrates a simple put_pixel(<!-- -->)
- function for RGB pixbufs with 8 bits per channel with an alpha

- <note>
- <para>
- If you are doing memcpy() of raw pixbuf data, note that the
- last row in the pixbuf may not be as wide as the full
- rowstride, but rather just as wide as the pixel data needs to
- be. That is, it is unsafe to do <literal>memcpy (dest,
- pixels, rowstride * height)</literal> to copy a whole pixbuf.
- Use gdk_pixbuf_copy() instead, or compute the width in bytes
- of the last row as <literal>width * ((n_channels *
- bits_per_sample + 7) / 8)</literal>.

-<para>
-If &gdk-pixbuf; has been compiled with GModule support, it can be extended by
-modules which can load (and perhaps also save) new image and animation
-formats. Each loadable module must export a
-#GdkPixbufModuleFillInfoFunc function named <function>fill_info</function> and
-a #GdkPixbufModuleFillVtableFunc function named
-<function>fill_vtable</function>.
-</para>
-
-<para>
-In order to make format-checking work before actually loading the modules
-(which may require dlopening image libraries), modules export their
-signatures (and other information) via the <function>fill_info</function>
-function. An external utility, <command>gdk-pixbuf-query-loaders-3.0</command>,
-uses this to create a text file containing a list of all available loaders and
-their signatures. This file is then read at runtime by &gdk-pixbuf; to obtain
-the list of available loaders and their signatures.
-</para>
-
-<para>
-Modules may only implement a subset of the functionality available via
-#GdkPixbufModule. If a particular functionality is not implemented, the
-<function>fill_vtable</function> function will simply not set the corresponding
-function pointers of the #GdkPixbufModule structure. If a module supports
-incremental loading (i.e. provides #begin_load, #stop_load and
-#load_increment), it doesn't have to implement #load, since &gdk-pixbuf; can
-supply a generic #load implementation wrapping the incremental loading.

-Functions for reference counting and memory management on pixbufs.
-
-<!-- ##### SECTION Long_Description ##### -->
- <para>
- #GdkPixbuf structures are reference counted. This means that an
- application can share a single pixbuf among many parts of the
- code. When a piece of the program needs to keep a pointer to a
- pixbuf, it should add a reference to it by calling g_object_ref().
- When it no longer needs the pixbuf, it should subtract a reference
- by calling g_object_unref(). The pixbuf will be destroyed when
- its reference count drops to zero. Newly-created #GdkPixbuf
- structures start with a reference count of one.
- </para>
-
- <note>
- <para>
- As #GdkPixbuf is derived from #GObject now, gdk_pixbuf_ref() and
- gdk_pixbuf_unref() are deprecated in favour of g_object_ref()
- and g_object_unref () resp.
- </para>
- </note>
-
- <para>
- <emphasis>Finalizing</emphasis> a pixbuf means to free its pixel
- data and to free the #GdkPixbuf structure itself. Most of the
- library functions that create #GdkPixbuf structures create the
- pixel data by themselves and define the way it should be freed;
- you do not need to worry about those. The only function that lets
- you specify how to free the pixel data is
- gdk_pixbuf_new_from_data(). Since you pass it a pre-allocated
- pixel buffer, you must also specify a way to free that data. This
- is done with a function of type #GdkPixbufDestroyNotify. When a
- pixbuf created with gdk_pixbuf_new_from_data() is finalized, your
- destroy notification function will be called, and it is its
- responsibility to free the pixel array.

-Scaling
-
-<!-- ##### SECTION Short_Description ##### -->
-Scaling pixbufs and scaling and compositing pixbufs
-
-<!-- ##### SECTION Long_Description ##### -->
- <para>
- The &gdk-pixbuf; contains functions to scale pixbufs, to scale
- pixbufs and composite against an existing image, and to scale
- pixbufs and composite against a solid color or checkerboard.
- Compositing a checkerboard is a common way to show an image with
- an alpha channel in image-viewing and editing software.
- </para>
-
- <para>
- Since the full-featured functions (gdk_pixbuf_scale(),
- gdk_pixbuf_composite(), and gdk_pixbuf_composite_color()) are
- rather complex to use and have many arguments, two simple
- convenience functions are provided, gdk_pixbuf_scale_simple() and
- gdk_pixbuf_composite_color_simple() which create a new pixbuf of a
- given size, scale an original image to fit, and then return the
- new pixbuf.
- </para>
-
- <para>
- Scaling and compositing functions take advantage of MMX hardware
- acceleration on systems where MMX is supported. If gdk-pixbuf is built
- with the Sun mediaLib library, these functions are instead accelerated
- using mediaLib, which provides hardware acceleration on Intel, AMD,
- and Sparc chipsets. If desired, mediaLib support can be turned off by
- setting the GDK_DISABLE_MEDIALIB environment variable.
- </para>
-
- <para>
- The following example demonstrates handling an expose event by
- rendering the appropriate area of a source image (which is scaled
- to fit the widget) onto the widget's window. The source image is
- rendered against a checkerboard, which provides a visual
- representation of the alpha channel if the image has one. If the
- image doesn't have an alpha channel, calling
- gdk_pixbuf_composite_color() function has exactly the same effect
- as calling gdk_pixbuf_scale().
- </para>

-<!-- ##### ENUM GdkInterpType ##### -->
- <para>
- This enumeration describes the different interpolation modes that
- can be used with the scaling functions. @GDK_INTERP_NEAREST is
- the fastest scaling method, but has horrible quality when
- scaling down. @GDK_INTERP_BILINEAR is the best choice if you
- aren't sure what to choose, it has a good speed/quality balance.
-
- <note>
- <para>
- Cubic filtering is missing from the list; hyperbolic
- interpolation is just as fast and results in higher quality.
- </para>
- </note>
- </para>
-
-@GDK_INTERP_NEAREST: Nearest neighbor sampling; this is the fastest
-and lowest quality mode. Quality is normally unacceptable when scaling
-down, but may be OK when scaling up.
-@GDK_INTERP_TILES: This is an accurate simulation of the PostScript
-image operator without any interpolation enabled. Each pixel is
-rendered as a tiny parallelogram of solid color, the edges of which
-are implemented with antialiasing. It resembles nearest neighbor for
-enlargement, and bilinear for reduction.
-@GDK_INTERP_BILINEAR: Best quality/speed balance; use this mode by
-default. Bilinear interpolation. For enlargement, it is
-equivalent to point-sampling the ideal bilinear-interpolated image.
-For reduction, it is equivalent to laying down small tiles and
-integrating over the coverage area.
-@GDK_INTERP_HYPER: This is the slowest and highest quality
-reconstruction function. It is derived from the hyperbolic filters in
-Wolberg's "Digital Image Warping", and is formally defined as the
-hyperbolic-filter sampling the ideal hyperbolic-filter interpolated
-image (the filter is designed to be idempotent for 1:1 pixel mapping).

-
- * gdk-pixbuf.c: don't #define it here. Remove GDK_PIXBUF_VAR from

-
- * Makefile.am: .def file belongs in $(srcdir). Patch by Marko
- Lindqvist.
-
-2008-05-02 Michael Natterer <mitch@imendio.com>
-
- * Makefile.am (stamp-gdk-pixbuf-marshal.h): deprecate the entire

- shouldn't be used by anybody.
-
-2008-03-21 Tor Lillqvist <tml@novell.com>
-
- Import the GDI+ gdk-pixbuf loaders for Windows by Dominic
- Lachowicz and Alberto Ruiz into the GTK+ tree, from the
- gdip-pixbuf-loader module.
-
- * Makefile.am: Add the bits and pieces for the GDI+ loaders. When
- building GDI+ loaders don't build the traditional ones for the
- same formats. Always build the traditional PNG loader, though, as
- it isn't possible to read and write PNG tEXt chunks through GDI+,
- and GIMP at least needs that functionality in the gdk-pixbuf PNG
- loader.
-
- Either build all the GDI+ loaders (except the PNG one) into
- libgdk-pixbuf, or build them all as DLLs. I don't see any reason
- to enable cherry-picking among them whether to build in or not.
-
- * io-gdip-animation.c

-
- * gdk-pixbuf-io.c: Add the bits and pieces for built-in GDI+
- loaders.
-
- == ChangeLog from gdip-pixbuf-loaders follows: ==
-
-2008-03-19 Tor Lillqvist <tml@novell.com>
-
- * src/io-gdip-utils.c: Drop misleading old comment.
-
- * src/io-gdip-native.h: Fix typo: s/WINGDIAPI/WINGDIPAPI/.
-
-2008-03-17 Tor Lillqvist <tml@novell.com>
-
- * src/io-gdip-utils.h (MODULE_ENTRY): Use the more descriptive
- INCLUDE_gdiplus instead of INCLUDE_gdi. (Will be used when this is
- moved to GTK+ and the gdip loaders are built-in in libgdk-pixbuf.)
- Use G_MODULE_EXPORT so that only fill_info and fill_vtable get
- exported in the separate loader DLLs case.
-
- * src/io-gdip-emf.c
- * src/io-gdip-ico.c
- * src/io-gdip-wmf.c: Use unique type parameters to MODULE_ENTRY so
- that we won't get clashes when building all the gdip loaders in to
- libgdk-pixbuf.
-
-2008-03-17 Tor Lillqvist <tml@novell.com>
-
- * src/Makefile.am: Remove libpixbufloader-gdip.la, and add missing
- loaders to loader_LTLIBRARIES. Set loaderdir to use proper GTK+
- binary version using pkg-config. Add final newline.
-
-2008-03-15 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * io-gdip.c: Remove
- * io-gdip-ico.c:
- * io-gdip-wmf.c:
- * io-gdip-emf.c: Separate these into their own loaders, so that existing
- code that calls "gdk_pixbuf_loader_for_type()" and friends continues
- to work as expected.
- * Makefile.test:
- * Makefile.am: Reflect the above changes
- * io-gdip-native.h:
- * io-gdip-utils.c: Better error reporting; handle metafiles properly
- (loading them as bitmaps doesn't work; you have to load them as a
- generic image or metafile and then draw them onto a bitmap)
-
-2008-03-06 Alberto Ruiz <aruiz@gnome.org>
-
- * configure.ac: Use the .exe version of the gdk query loaders if the build
- is for a windows target.
-
-2008-03-04 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip-utils.c: More informative error codes, taken from the COM HRESULT
-
-2008-03-03 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip-native.h:
- * src/io-gdip-jpeg.c: Support setting the JPEG's quality, just like GdkPixbuf's
- built-in JPEG encoder
- * src/io-gdip-png.c: Support setting the PNG's compression level, just like
- GdkPixbuf's built-in PNG encoder
-
-2008-02-25 Tor Lillqvist <tml@novell.com>
-
- * configure.ac: Move AC_DISABLE_STATIC before AC_PROG_LIBTOOL so
- that it works better.
-
-2008-02-24 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip-animation.[ch]: Animation class and interator
- * src/io-gdip-utils.c: Use animation iter. GDI+ animations now work.
-
-2008-02-24 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip-utils.c: Simple animation working; need to use a more sophisticated
- animation class
-
-2008-02-24 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/*.c: Change to GTK+-style indentation; stub out some stuff
- for animation support
-
-2008-02-22 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/Makefile.am: Build those other libraries using automake too;
- track dependencies properly
-
-2008-02-22 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/*.[ch]: Separate out formats that are writable into their
- own plugins. The GDI+ loader can now save as BMP, GIF, JPEG, PNG,
- or TIFF. Also, some tweaks so that the format plugins can be
- statically compiled into GTK+ if we choose to do so.
-
-2008-02-22 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip-utils.c (GetEncoderClsid): Add support for BMP,
- JPEG, GIF, and TIFF
-
-2008-02-22 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/*.[ch]: Saving images to PNG now works. Conditionally compiled
- until I get GdkPixbuf's saving architecture straightened out.
-
-2008-02-21 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip-utils.c (io_gdip_init): Make this idempotent
- * src/io-gdip.c: Function that fills the GdkPixbufIO vtable. To be used across
- various GDI+-based plugins
-
-2008-02-21 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/*.[ch]: If you #define GDIP_TEST_SAVING, you should be able
- to save a pixbuf to a PNG via GDI+. WARNING: UNTESTED CODE
-
-2008-02-21 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/*.[ch]: Infrastructure for saving GdkPixbufs to GdkPixbufSaveFunc callbacks.
- Should be trivial to write a PNG or JPEG saver now.
-
-2008-02-20 Tor Lillqvist <tml@novell.com>
-
- * src/io-gdip-utils.c: Drop the wrapper functions that each call
- GetProcAddress(). Instead just use a bunch of function pointers
- and initialise them at the same time in io_gdip_init().
-
-2008-02-19 Dom Lachowicz <domlachowicz@gmail.com>
-
- * src/*.[ch]: ARGB isn't pre-multiplied; first stab @ metadata
-
-2008-02-19 Tor Lillqvist <tml@novell.com>
-
- * src/io-gdip.c
- * src/io-gdip-utils.c
- * src/test.c: Use spaces instead of tabs. Use 2-column indentation
- offset which was the original intent. Remove trailing whitespace.
-
-2008-02-19 Tor Lillqvist <tml@novell.com>
-
- * configure.ac: Use AC_DISABLE_STATIC. It makes no sense to build
- a static library of this.
-
- * autogen.sh: Take ACLOCAL_FLAGS into consideration.
-
-2008-02-18 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * src/*.[ch]: Fix image size (don't need to add + 1); framework
- for supporting animations or multi- paged TIFFs
-
-2008-02-18 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * src/*.[ch]: If the source image doesn't have alpha, don't create
- an opaque alpha channel in the pixbuf
-
-2008-02-18 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * src/*.c: Whitespace fixes
-
-2008-02-18 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip.c: Support pixbuf scaling
-
-2008-02-18 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip.c: Fill pixbuf properly; propegate errors. Plugin
- now works for non-animations
-
-2008-02-18 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip.c: Move initialization to fill_vtable
- * src/io-gdip-utils.c: GDI+ functions return Status, not HRESULT,
- so we can't use SUCCEEDED() to test if they worked or not
-
-2008-02-18 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip.c (gdk_pixbuf__gdip_image_stop_load): Un-premultiply alpha

- only called once
-
-2008-02-18 Dominic Lachowicz <domlachowicz@gmail.com>
-
- * src/io-gdip-utils.c: Make GDI+ function pointers static so that
- we only load them once

-2006-10-29 Tor Lillqvist <tml@novell.com>
-
- * pixbufloader_*.def
- * Makefile.am (EXTRA_DIST): Remove pixbufloader_*.def, they are
- not used. (#365388) They were all identical, and exported just two
- symbols, so if somebody needs them for a MSVC build that doesn't
- use built-in modules it's trivial to hack makefile.msc to produce
- a common .def file for the loaders. The two symbols that need to
- be exported are fill_info and fill_vtable.
-
-2006-10-11 Tor Lillqvist <tml@novell.com>
-
- Enable having some loaders built-in even if loading the others
- dynamically. Have loaders in the same order as in configure.in in
- all places where they are handled/listed.
-
- * Makefile.am: Define the STATIC_FOO_LIB and FOO_LIB macros
- conditionally depending on whether said loader is built-in or
- not. Use the names libstatic-pixbufloader-foo.la instead of
- libpixbufloader-static-foo.la for the built-in ones so that the
- "echo libpixbufloader-*.la" won't match them.
-
- * gdk-pixbuf-io.c: Reorganize code as to plumb the built-in
- loaders also if USE_GMODULE. Don't warn about a missing
- gdk-pixbuf.loaders file if we have at least one included loader.
-
- * gdk-pixbuf-private.h
- * io-*.c: Don't define a generic MODULE_ENTRY, as we can't use it
- in the loaders anyway. Each loader needs to check if INCLUDE_foo
- is defined.

-
- * io-ico.c (DecodeHeader): Stop discriminating against 32bpp ICOs

- (lsb_16): New functions to fetch 32 or 16-bit little-endian values

-
- * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
- account!!! Fixes #82515.
-
- [This bug is not present in the GNOME 1.4 branch as its XPM loader
- does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
- no row padding and then uses gdk_pixbuf_new_from_data() on it.]
-
- [IMPORTANT: The comment above is to make my life easier when
- merging stuff across branches. If you make changes to gdk-pixbuf
- in either branch, please include a comment in the ChangeLog that
- indicates whether this should be merged into the other branch.
- Thanks!]

-
-2001-06-11 Havoc Pennington <hp@redhat.com>
-
- * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
- already includes top_builddir
-
-2001-06-08 Havoc Pennington <hp@redhat.com>
-
- * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
- bogus g_return_if_fail

- Makes things a bit more robust, and adds test-loaders.c
- which is good for finding further robustness bugs to fix.
-
- * io-tiff.c: Try to work around libtiff suckiness a bit;
- put a giant thread lock on the whole loader,
- paranoically check both whether error handlers were called and
- also whether functions return false. Handle case where width or
- height is 0. Various cleanups.
-
- * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
- if it existed

- (pixops_composite_color_nearest): Use a more accurate (and
- correct, to begin with) compositing method. This cures checks
- showing through on images with no alpha.

- bytes unfilled.
-
- * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints

-
-2001-02-17 Havoc Pennington <hp@pobox.com>

-
-2001-02-07 Alexander Larsson <alexl@redhat.com>
-

-
-2001-02-06 Christophe Merlet <redfox@eikonex.org>
-

-
-Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
-
- * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
- we finally need the gobject->gruntime rename.
-
- * *.c: scratched calls to g_type_init(), there's simply no point in
- doing that, use gtk_init().
-
-2001-02-01 Havoc Pennington <hp@pobox.com>
-
- * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field

-
-2001-01-22 Havoc Pennington <hp@redhat.com>
-
- * Makefile.am: Add built marshaller files to support
- GdkPixbufLoader signals
-
- * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
- GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
- module location, rather than acting as a fallback, because we are
- using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
-
- * gdk-pixbuf.h: include gdk-pixbuf-loader.h
-
- * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here

- parsing of the image.
-
- * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
-
- * io-*.c: make individual operations static, and add fill_vtable
- functions which are exported. Fix the collection of type warnings
- that surfaced, including a number of functions that didn't
- properly take a GError and some that weren't
- const-correct. Involved adding error handling for a few loaders.
-
- * gdk-pixbuf-io.h: Add error reporting to stop_load function
-
- * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
- a function that fills in the GdkPixbufModule vtable, instead of
- looking up all the image functions individually; this means we
- can get type safety within modules for the loader functions.
- Also it means you don't have to keep the statically compiled and
- GModule versions in sync.
-
- * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
-
- * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
-
- * gdk-pixbuf.h: nuke gdk_pixbuf_init()
-

- () here
-
- * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
-
- * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
- g_type_init() here
-
-2001-01-20 John Harper <jsh@eazel.com>
-
- * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
- collision between Xlib's RdBitF.c and io-tiff.c
-
- * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
- io-xbm.c support

- compiles, and works fine in the stable module ]
-
-2001-01-18 Tor Lillqvist <tml@iki.fi>

-2000-11-11 Hans Breuer <Hans@Breuer.Org>
-
- * gdk-pixbuf-io.c : Fix all function prototype macros for self

-
-2000-11-11 Tor Lillqvist <tml@iki.fi>
-
- * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
-

- one level up from here?
-
- * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
- * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
- Open file in binary mode. This *is* standard C. (No-op on Unix,
- of course.)
-
- * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
-
- * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
- mktemp() and open().
- (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
-
- * pixops/*.S: The Gas from mingw32 doesn't like the .type
- pseudo-op. Conditionalise on __MINGW32__, but probably
- should conditionalise on Gas version instead? Or could we
- do without .type on all systems?
-
- * pixops/timescale.c: Use g_get_current_time()
- instead of gettimeofday().

-
-Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
-
- * gdk-pixbuf.c: Add <string.h> include.

- * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
- * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
- use g_object_new() instead of g_type_create_instance() which
- is a private function for fundamental type implementations.
-
-Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
-
- * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
- soname scheme for gdk-pixbuf.
-
-2000-06-21 Havoc Pennington <hp@pobox.com>
-
- * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
- (i.e. derivation is not allowed, and there are no virtual methods
- anyway).
- (gdk_pixbuf_preinit): Call g_type_init() here.
- (gdk_pixbuf_init): Add a user-friendly init function, for users
- of standalone gdk-pixbuf
-
- * gdk-pixbuf-animation.c: Convert to GObject, in the same
- way GdkPixbufAnimation was done.
-
- * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
- gdk_pixbuf_finalize() from API, since these are broken and don't
- make sense with new GObject stuff.
-
-Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
-
- * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
- support a GDK_PIXBUF_MODULEDIR env variable as a secondary
- load location.
-
-2000-06-10 Federico Mena Quintero <federico@helixcode.com>
-
- * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
- so I needed something to warm my thighs. Running plain infinite
- loops on your laptop to make it hot is not very much fun. A demo
- of the gdk-pixbuf scaling functions is way better, and looks
- prettier, too.
-
- * configure.in (AC_OUTPUT): Added the demo Makefile.
-
- * Makefile.am (SUBDIRS): Added the demo directory.
-
-2000-06-09 Larry Ewing <lewing@helixcode.com>
-
- * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
- setjmp for the png error handler. It seems setting the error
- handling functions does not avoid the jump, and so not calling
- setjmp was causing the incremental loader to jump into lala land.
- (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
- not sure this one is actually required but the docs say it must be
- set for every call to a png_* function.
- Also changed the comment to reflect the fact that setting the
- error handlers does _not_ avoid the longjmp.
-
-2000-06-06 Larry Ewing <lewing@helixcode.com>
-
- * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
- take frame offest into account when trying to calculate the
- animation bbox. Also set the width to the width not the height.
- (gdk_pixbuf_loader_animation_done): cycle over the frames to
- calculate bbox because now we finally have all the offset
- information for each frame.
-
-2000-06-05 Mathieu Lacage <mathieu@gnome.org>
-
- * configure.in: add some gtk parameters to the
- GDK_PIXBUF_LIB?�?S and GDK_PIXBUG_INCLUDEDIR vars. One more
- fight in my crusade for strange prefix compile...
-
-2000-05-30 Not Zed <NotZed@HelixCode.com>
-
- * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
- Initialise the error handler exit routine to our own. Note this
- means that every function that accesses the jpeg lib on this
- object MUST do a setjmp.
- (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
- lib for handling fatal error.
- (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
- your applications dont quit if there's a jpeg error!
-
-2000-05-30 Federico Mena Quintero <federico@helixcode.com>
-
- * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
- from Frank de Lange <frank@unternet.org>.
-
-2000-05-09 Darin Adler <darin@eazel.com>
-
- * gdk-pixbuf/test-gdk-pixbuf.c:
- Fixed includes to get rid of accidental GNOME dependency.
-
-2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
- * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
-
-2000-05-22 Federico Mena Quintero <federico@helixcode.com>
-
- * configure.in: Bumped version number to 0.8.0.
-
- * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
- file was not being distributed.
-
- * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
-
-2000-05-09 Darin Adler <darin@eazel.com>
-
- * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
- (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
- (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
- formats to 32-bit formats to re-use the high bits of the color values
- so that white maps to full white.
-
-Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
-
- * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
- detailed information about the structure and algorithms
- of pixops so people can fix it instead of breaking it.
-
-2000-05-04 Darin Adler <darin@eazel.com>
-
- * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
- (composite_pixel), (composite_line):
- * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
- Now that Owen explained the algorithm, I think I implemented it
- right for the cases where the destination pixbuf is not opaque.
- The test does seem to confirm it.
-
-2000-05-04 Darin Adler <darin@eazel.com>
-
- * gdk-pixbuf/.cvsignore:
- * gdk-pixbuf/Makefile.am:
- * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
- (load_pixel), (simple_composite_test_one),
- (simple_composite_test_one_type), (simple_composite_test), (main):
- Added some tests of composite to highlight problems in the old
- implementation. These tests run without any user interaction.
- Just do "make check".
-
- * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
- (composite_pixel), (composite_line): Fix composite to do a textbook
- "A over B" composite. This was clearly the intent, and it was easy
- to fix the code to do it. (Note to those that read my earlier tries
- at a patch; this version fixes typos that were present in all
- my patch attempts. I checked the final version by adding more tests.)
-
-2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
-
- * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
- offset y coordinate accordining to render_y0.
-
- * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
- dest_x, dest_y.
-
-2000-04-22 James Henstridge <james@daa.com.au>
-
- * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
- package to the devel package. The only file installed in bin is
- gdk-pixbuf-config, which belongs in -devel. This should allow having
- multiple versions of the main gdk-pixbuf package installed.
-
-2000-04-17 Karl Eichwalder <ke@suse.de>
-
- * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
- Reported by Jens Finke.
-
-2000-04-14 Tomasz K?�?opczko <kloczek@pld.org.pl>
-
- * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
- $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
-
-2000-04-13 James Henstridge <james@daa.com.au>
-
- * configure.in: when performing the configure check to see if
- gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
- rather than the other way round. Also, call AC_MSG_RESULT in the
- even that dynamic modules were not supported.
-
-2000-04-12 Federico Mena Quintero <federico@helixcode.com>
-
- This comes from an excellent idea by Tim Janik (timj@gtk.org) to
- hook to the last unref operation.
-
- * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
- function to set the last unref handler for a pixbuf.
- (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
- It calls the pixbuf's destroy notification function and frees the
- GdkPixbuf structure itself.
- (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
- available.
-
- * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
- for the last unref handler and its user data.
-
- * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
- g_new0() to allocate the pixbuf.
-
- * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
- Fixed the call to gtk_signal_new() for the "frame_done" signal; it
- was not specifying the `frame' argument.
-
- * gdk-pixbuf/gdk-pixbuf-animation.c
- (gdk_pixbuf_animation_get_width): Fixed docstring.
- (gdk_pixbuf_animation_get_height): Likewise.
- (gdk_pixbuf_animation_get_num_frames): Likewise.
- (gdk_pixbuf_animation_get_frames): Likewise.
-
- * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
- types.
-
- * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
-
- * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
-
- * doc/tmpl/refcounting.sgml: Updated with the information about
- the last unref handler.
-
- * doc/tmpl/*.sgml: Markup tweaks.
-
- * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
- update the libtool version number for libgnomecanvaspixbuf as
- well.
- (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
- as well, or the old ones won't work with the new stuff. Also,
- renamed the modules as follows.
-
- * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
- modules are called "libpixbufloader-<format>.so" instead of
- "libpixbuf-<format>.so". They needed renaming so that the new
- loaders won't overwrite the old ones; even with the versioning
- stuff, the new .so symlink to the .so.1.0.0 would overwrite the
- old real .so file.
-
-2000-04-12 Paolo Molaro <lupus@debian.org>
-
- * .cvsignore, src/.cvsignore: shut up cvs.
-
-2000-04-11 Federico Mena Quintero <federico@helixcode.com>
-
- Most of this patch is based on a patch by Havoc Pennington

-
- * gdk-pixbuf/gdk-pixbuf-render.c
- (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
- mask rectangle for pixbufs without an alpha channel, set the
- *mask_return to NULL.
-
- * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
-
- * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
-
- * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
- preconditions. Maybe we should also check for the colorspace,
- bits per pixel, and such.
- (gdk_pixbuf_composite): Likewise.
- (gdk_pixbuf_composite_color): Likewise.
- (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
- cannot allocate the new pixbuf.
- (gdk_pixbuf_composite_color_simple): Likewise.
-
- * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):

- the version number of the libtool library to indicate that this
- definitely is not compatible with the old usage. I know you love
- me. I know you do.
-
- * configure.in: Bumped version number to 0.7.0.
-
- * README: Updated.
-
- * gdk-pixbuf-config.in (--libs): We no longer require libart.
-
- * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
-
- * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
-
-2000-04-06 Jonathan Blandford <jrb@redhat.com>
-

- testanimation frames.
-

-
-2000-04-01 Federico Mena Quintero <federico@helixcode.com>
-
- * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
- is private information, and the art_pixbuf will go away soon.
-
-2000-03-31 Mark Crichton <crichton@gimp.org>
-
- * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount

-
-2000-03-28 Radek Doulik <rodo@helixcode.com>
-
- * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for

- progressive animation loading work
-
- * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):

- it can load .BMP files that are not generated by The Gimp
- as well.

-
- * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
- fix the last auto* build bug (where we have libart, but no
- gnome-libs)
-
- * gdk-pixbuf/Makefile.am: Same.
-
-2000-02-28 Matt Wilson <msw@redhat.com>
-
- * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,

-
-2000-02-26 Federico Mena Quintero <federico@helixcode.com>
-
- * README: We don't require libgif/ungif nor libXpm.

- Fixed typo in prototype name.
-

- something more meaningful; now it is "checking whether dynamic
- modules work".

- the timescale program.
-
- Integrated Miguel de Icaza's <miguel@gnu.org> patch for optionally

-2000-01-01 Federico Mena Quintero <federico@helixcode.com>
-
- * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
- counting to animations. A web browser may want to share a single
- copy of an animated GIF if it appears multiple times in a web
- page, for example.
-
- * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
- animation functions here.
- (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL

- not NULL. Updated inline documentation.

- (gdk_pixbuf_animation_unref): New function.
- Removed gdk_pixbuf_animation_destroy() in favor of reference
- counting.

- size, respectively.
- (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
- const char **.
-

- with a reference count of 1.
-
- * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added

-
- * gdk-pixbuf/io-gif.c: finished work to make animated gifs load

-
-1999-12-17 Jonathan Blandford <jrb@redhat.com>
-
- * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
- moved the file here. It seems natural to put this function here,
- as that's where the gdk_pixbuf_new_from_file function is, but it's
- still a little convoluted. The source files might be played with
- in a bit.
-
-1999-12-14 Jonathan Blandford <jrb@redhat.com>
-
- * gdk-pixbuf/gdk-pixbuf-loader.c

- properly if the optimised version will do, otherwise use the
- fallback function for all other data formats.
-
- * gdk-pixbuf/Makefile.am: Re-enabled building of
- textpixbuf-drawable.
-
- * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
- gdk_pixbuf_get_from_drawable().

-
-1999-11-29 Owen Taylor <otaylor@redhat.com>
-
- * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
- Keep the mask around until after we draw ... since
- the GC changes aren't flushed to the X server until we
- draw, destroying it before that may result in BadPixmap
- errors.
-
-1999-11-30 Havoc Pennington <hp@pobox.com>
-
- * configure.in: Add AM_CONDITIONAL for inside gnome-libs
-
- * src/Makefile.am: conditionalize GnomeCanvasPixbuf
-
-1999-11-29 Federico Mena Quintero <federico@redhat.com>
-
- * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
- should be made conditional, not blindly commented out.
-
-1999-11-29 Jonathan Blandford <jrb@redhat.com>
-
- * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
- handle .ico files. Cool.
-
-1999-11-24 Jonathan Blandford <jrb@redhat.com>
-
- * src/io-bmp.c (OneLine24): new patch from Arjan to handle
- compressed bmps.
-
-1999-11-24 James Henstridge <james@daa.com.au>
-
- * configure.in (AC_OUTPUT): altered hack to place the symlink in the
- top builddir rather than src. This still builds fine, and does not
- get gtk-doc into an infinite loop when trying to find all the source
- files.
-
-1999-11-23 Jonathan Blandford <jrb@redhat.com>
-
- * Removed #PRAGMA } from headers. Also, make compile if you don't
- have it installed, already.
-
-1999-11-22 Federico Mena Quintero <federico@redhat.com>
-
- * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
- temporary buffer to the size of the interesction of the bounding
- box and the expose area, not the whole expose area. This speeds
- up things a lot.
-
- * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
- not paint black on the mask, since we already cleared it in a
- single gdk_draw_rectangle() operation.
-
-1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
-
- * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
-
-1999-11-22 Havoc Pennington <hp@pobox.com>
-
- * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
- <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
- dependencies to LIBADD variables for loadable modules. Necessary
- for a Java dynamic loading thing to be able to figure it out.
-
-1999-11-22 Havoc Pennington <hp@pobox.com>
-
- * src/io-png.c (image_load_increment): Call the update_area
- callback depending on the number of rows loaded in this increment.
-
- * src/testpixbuf.c (main): slow down the progressive load demo
-
-1999-11-16 Havoc Pennington <hp@pobox.com>
-
- * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
-
-1999-11-22 Jonathan Blandford <jrb@redhat.com>
-
- * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
- for srcdir != buildir != . Beats me why; I can't figure it out.
- AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
-
-1999-11-21 Jonathan Blandford <jrb@redhat.com>
-
- * src/gdk-pixbuf-io.c: added io-bmp from Arjan
- <arjan@fenrus.demon.nl>
-
-1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
-
- * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
- Rework/reorder of the code. Each case has been separated into
- another function; its big but it should be quick.
- gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
- opaque alpha information. Not all depths/formats have been
- tested, but 8, 15/16 and 24 (alinged 32) should work ok.
-
-1999-11-17 Larry Ewing <lewing@gimp.org>
-
- * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
- implement the bounds method correctly.
- (compute_viewport_affine): compute the affine need to fit the
- image within the viewport given by the args.
- (compute_render_affine): call compute_viewport_affine.
-
-1999-11-16 Havoc Pennington <hp@pobox.com>
-
- * src/gdk-pixbuf-drawable.h: Use includes from the current
- directory, not the system directory.
-
-Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
-
- * src/testpixbuf-drawable.c: use includes from the current directory
- rather then from the system include directory as gdk-pixbuf
- includes are not yet installed when this is compiled.
-
-1999-11-13 Cody Russell <bratsche@dfw.net>
- * src/testpixbuf-drawable.c: Added a test program for drawable
- code.
-
- * src/Makefile.am: Build testpixbuf-drawable.

-
- * src/io-png.c: Fixed some incompatible pointer initializations.
-
- * src/io-jpeg.c (image_load_increment): Remove unused variable.
-
-1999-11-09 Michael Fulbright <drmike@redhat.com>
-
- * src/testpixbuf.c: Fixed it to use timeout to read from file
- for progressive loading. Set TBF_KBPS=n, where n is the number of
- kilobytes/second to simulate in downloading. n has to be an integer.
-
- * src/io-jpeg.c: Slight cosmetic cleanup.
-
- * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
- PBM loading has a similar problem and will address tomorrow.

-
- * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
- gdk-pixbuf-drawable stuff.

-
-1999-11-09 Michael Fulbright <drmike@redhat.com>
-
- * src/io-pnm.c : Finished progressive PNM loading code. Should handle
- all types of PNM files now.
-
- * src/io-jpeg.c (image_load_increment): Figured out problem with
- loading Progressive JPEG's progressively (say that 10 times fast).
- Currently for Progressive JPEG's the entire image is loaded before
- it is displayed. libjpeg supports a fancier mechanism which I may
- implement later.
-
- With these changes all JPEG formats appear to load properly for me.
-
-1999-11-08 Jonathan Blandford <jrb@redhat.com>
-
- * src/io-ras.c (image_load_increment): Final patch from Arjan.
- Seems to do progressive loading.
-
-1999-11-08 Michael Fulbright <drmike@redhat.com>
-
- * src/io-pnm.c image_load (): Fixed so we do not create a separate
- pixel buffer when reading in image - we reuse the pixel data in
- the GdkPixbuf structure instead.
-
-1999-11-08 Michael Fulbright <drmike@redhat.com>
-
- * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
- ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
- I can't seem to find a utility to convert into this format.
- Next is to add progressive loading support for the PNM format.
-
-1999-11-07 Federico Mena Quintero <federico@redhat.com>
-
- * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
- of the width, height, x, and y setting and pixels arguments.
-
-1999-11-05 Jonathan Blandford <jrb@redhat.com>
-
- * src/io-ras.c (image_load): third patch. Now it seems to load.

-
- * src/io-ras.c (image_load): new file from Arjan van de Ven
- <arjan@fenrus.demon.nl> to begin the ras loader.
-
-1999-11-05 Federico Mena Quintero <federico@redhat.com>

- for internal use only.
-
- * doc/gdk-pixbuf.sgml: Likewise.
-
- * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
-
-1999-11-05 Michael Fulbright <drmike@redhat.com>
-
- * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
- files from a file. Next step is support for ASCII files, and
- then incremental loading.
-
-1999-11-04 Federico Mena Quintero <federico@redhat.com>
-
- * Makefile.am: Added doc to SUBDIRS.
-
-1999-11-04 Michael Fulbright <drmike@redhat.com>

-1999-11-04 Havoc Pennington <hp@pobox.com>
-
- * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
- docs, explain what a dither offset is for.
- (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
- this function vs. gdk_pixbuf_render_to_drawable().
-
-1999-11-04 Havoc Pennington <hp@pobox.com>
-
- * configure.in: Use libart-config correctly; find gnome-config
- separately. Fix GNOME_LIBS to be correct in "no gnome installed
- yet" case.
-
- * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
- library list.
-
- Patch untested in the inside-gnome-libs case, I need to commit
- then check out to the gnome-libs I'm using.
-
-1999-11-04 Michael Fulbright <drmike@redhat.com>
-
- * src/io-jpeg.c (image_begin_load): Add update_func callback.
- * src/io-jpeg.c (image_load_increment): Call updated callback when
- new graphic data decoded.
-
-1999-11-04 Jonathan Blandford <jrb@redhat.com>

- lib*gif!!!!
-
-1999-11-03 Michael Fulbright <drmike@redhat.com>
-
- * src/io-jpeg.c (image_load_increment): Further removal of
- bugginess in local buffering code. Handles grayscale jpegs
- correctly now.
-
- * src/io-jpeg.c (image_load_stop): Was freeing local context

- sizes.
- (gif_get_lzw): set the transparency to the right val.
-
-1999-11-03 Federico Mena Quintero <federico@redhat.com>
-
- * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):

-
-1999-11-03 Larry Ewing <lewing@gimp.org>
-
- * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
- render_affine calculation for x,y offsets.
- (gnome_canvas_pixbuf_set_arg): add x,y args.
- (gnome_canvas_pixbuf_get_arg): add x,y args.
- (recompute_bounding_box): simply code using ArtDrect and the
- render_affine. Removed compute_xform_vectors as it was no longer
- needed.
-
-1999-11-03 Federico Mena Quintero <federico@redhat.com>
-
- * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
- doofus. Return a distance, not a boolean, for opaque images.
-
- * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
- rounding of bounding box coordinates.
- (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.

-
-1999-11-03 Jonathan Blandford <jrb@redhat.com>
-
- * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
-
-1999-11-03 Michael Fulbright <drmike@redhat.com>
-
- * src/io-jpg.c (image_load_increment): Fixed code which moved
- buffer around as new data comes in to work properly. JPEG progressive
- loading should be working now except for grayscale JPEG's, which I
- will look into next.
-
-1999-11-03 <sopwith@redhat.com>
- * src/testpixbuf.c: A GtkFunction needs to return a value for
- deterministic behaviour. Also put dot printing back in.
-
-1999-11-03 <jrb@redhat.com>
-
- * src/io-gif.c (gif_get_extension): Read 'til the next empty block
- correctly, now.
-
-1999-11-02 Cody Russell <bratsche@dfw.net>
- * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
- if part of the requested image is offscreen, rather than clipping
- the image.
-
-1999-11-02 Jonathan Blandford <jrb@redhat.com>
-
- * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
- for interlacing and progressive loading.
-
-1999-11-02 Cody Russell <bratsche@dfw.net>
- * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
- calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
-
-1999-11-02 Jonathan Blandford <jrb@redhat.com>
-
- * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
- It's a little slow though. )-:
-
-1999-11-02 Elliot Lee <sopwith@redhat.com>
- * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the

-
-1999-11-02 Federico Mena Quintero <federico@redhat.com>
-
- * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
- Implemented the ::point() method. We do a simple containment test
- instead of a full distance calculation since the canvas is going
- to change to that scheme, anyways.
-
-1999-11-02 Elliot Lee <sopwith@redhat.com>
-
- * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size
- of the chunks that are read from the input file.
-
-1999-11-02 Larry Ewing <lewing@gimp.org>
-
- * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
- render function.
- (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
- to class.
-
-1999-11-02 Federico Mena Quintero <federico@redhat.com>
-
- * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
- affine computation code from ::draw() to here, since it is needed
- by ::point() as well.
-
-1999-11-02 Elliot Lee <sopwith@redhat.com>
-
- * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
- three functions, and eliminate duplication of code from write()
- and close(). Also fix bug where the 128-byte header was being
- written twice.
-
-1999-11-01 Federico Mena Quintero <federico@redhat.com>
- * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
- bounding box computation.
-
-1999-11-01 Federico Mena Quintero <federico@redhat.com>
-
- * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
- Drawing affines seem to work. Bounding box is fubared. ::point()
- is not implemented. This is a work in progress.
-
- * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
- sources.
-
- * configure.in: Sigh. We need to link in libgnomeui for the
- canvas stuff. This mess will disappear when gdk-pixbuf gets
- folded into gnome-libs.
-
-1999-10-30 Jonathan Blandford <jrb@redhat.com>
-
- * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
- the right size, at a minimum, even if the image is squished and
- the wrong color.
- (ReadImage): lets get the offset right. This will let transparent
- gifs work.
-
-1999-10-29 Michael Fulbright <drmike@redhat.com>
-
- * src/io-jpeg.c: image_load_increment(): Fixed bug when
- image width was not a multiple of 4 - always use the
- gdk_pixbuf rowstride to increment pointers!
-
-1999-10-29 Michael Fulbright <drmike@redhat.com>
-
- * src/io-jpeg.c: Added first cut at progressive jpeg loading.
- Currently does not handle either progressive jpeg files (jpeg
- files with multiple scans at different quality settings), but
- I plan on adding this support soon. These are fairly rare in
- my experience, so it shouldn't slow people down too much.
- Grayscale jpegs also don't work but that should be easy to fix.
-
-1999-10-29 Michael Fulbright <drmike@redhat.com>
-
- * src/testpixbuf.c: Added title to windows so you can identify
- progressive and file windows.
-
-1999-10-29 Michael Fulbright <drmike@redhat.com>
-
- * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
- load the image handler when we determine the image type.
-
- * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
- previously static function load_image_handler () to
- a public function gdk_pixbuf_load_module (). It is needed in
- gdk-pixbuf-loader.c to load image handler modules. This function
- is different from gdk_pixbuf_get_module (), which only returns
- a reference to the required handler, because it actually loads
- the handler into memory. Both actions should possibly be combined
- in a convenience function since one w/o the other doesn't seem to
- make much sense.
-
-1999-10-28 Jonathan Blandford <jrb@redhat.com>
-
- * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
- 0 length buffer.
-
-1999-10-28 Federico Mena Quintero <federico@redhat.com>
-
- * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
- function to render a portion of a pixbuf to a drawable. Ignores
- alpha information and takes in a GC.
- (gdk_pixbuf_render_to_drawable_alpha): New function to render a
- portion of a pixbuf to a drawable. It automatically creates a GC
- and a clipping mask for alpha pixbufs.
-
-1999-10-28 Jonathan Blandford <jrb@redhat.com>
-
- * src/gdk-pixbuf.h: turned convenience macros into convenience
- functions so some error checking could be added.
-
- * src/io-tiff.c (image_load_increment): started work on the tiff
- non-incremental loader.
- (image_begin_load): Finished the incremental loader.
-
- * src/io-gif.c (image_load_increment): started work on the gif
- incremental loader.
-
- * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
-
-1999-10-27 Federico Mena Quintero <federico@redhat.com>
-
- * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
- function to threshold a pixbuf's alpha channel into a bitmap.
-
- * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
- contemplate future extensions to ArtPixBuf's formats.
-
- * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
-
- * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
- macros to fetch the ArtPixBuf's fields.
-
-1999-10-27 Havoc Pennington <hp@pobox.com>
-
- * src/testpixbuf.c (main): Display the progressive load
-
- * src/io-png.c (setup_png_transformations): Break transformation
- code into separate function
- (png_info_callback): Use setup_png_transformations
-
-1999-10-27 Havoc Pennington <hp@pobox.com>
-
- * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
- properly whether the XPM module has already been loaded
- (gdk_pixbuf_new_from_file): Check properly if loader module
- was already loaded (was checking if load symbol was present
- in order to decide whether to re-load; should check module !=
- NULL, then load != NULL)
- (image_handler_load): Check in present working directory,
- makes it easier to debug for now
- (file_formats): This array initializer was seriously on crack,
- was assigning a function pointer to a GModule*
-
- * src/testpixbuf.c (main): Change type of pixbuf_loader to
- GdkPixbufLoader*
-
-1999-10-27 Havoc Pennington <hp@pobox.com>
-
- * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_finalize):
- Fix typo that prevented compilation

-.TH GDK-PIXBUF-CSOURCE 1 "04 Sep 2001"
-.SH NAME
-gdk-pixbuf-csource \- C code generation utility for GdkPixbuf images
-.SH SYNOPSIS
-
-\fBgdk-pixbuf-csource\fP [\fIoptions\fP] [\fIimage\fP]
-.br
-\fBgdk-pixbuf-csource\fP [\fIoptions\fP] \fI--build-list\fP [[\fIname image\fP]...]
-
-.SH DESCRIPTION
-\fBgdk-pixbuf-csource\fP is a small utility that generates C code containing
-images, useful for compiling images directly into programs.
-
-.SH INVOCATION
-
-\fBgdk-pixbuf-csource\fP either takes as input one image file name to generate code
-for, or, using the \fI--build-list\fP option, a list of (\fIname\fP, \fIimage\fP)
-pairs to generate code for a list of images into named variables.
-
-.SS Options
-.TP
-\fI--stream
-Generate pixbuf data stream (a single string containing a serialized
-GdkPixdata structure in network byte order).
-
-.TP
-\fI--struct
-Generate GdkPixdata structure (needs the GdkPixdata structure definition from
-gdk-pixdata.h).
-
-.TP
-\fI--macros
-Generate *_ROWSTRIDE, *_WIDTH, *_HEIGHT, *_BYTES_PER_PIXEL and
-*_RLE_PIXEL_DATA or *_PIXEL_DATA macro definitions for the image.
-
-.TP
-\fI--rle
-Enables run-length encoding for the generated pixel data (default).
-
-.TP
-\fI--raw
-Disables run-length encoding for the generated pixel data.
-
-.TP
-\fI--extern
-Generate extern symbols.
-
-.TP
-\fI--static
-Generate static symbols (default).
-
-.TP
-\fI--decoder
-Provide a *_RUN_LENGTH_DECODE(image_buf, rle_data, size, bpp) macro definition
-to decode run-length encoded image data.
-
-.TP
-\fI--name=identifier
-Specifies the identifier name (prefix) for the generated variables or
-macros (useful only if \fI--build-list\fP was not specified).
-
-.TP
-\fI--build-list
-Enables (\fIname\fP, \fIimage\fP) pair parsing mode.
-
-.TP
-\fI-h, --help\fP
-Print brief help and exit.
-
-.TP
-\fI-v, --version\fP
-Print version and exit.
-
-.TP
-\fI--g-fatal-warnings
-Make warnings fatal (causes the program to abort).
-
-.PP
-
-.SH SEE ALSO
-The \fIGdkPixbuf\fP documentation, shipped with the \fIGtk+\fP distribution,
-available from \fIhttp://www.gtk.org\fP.
-
-.SH BUGS
-None known yet.

- * @width: Width of the image in pixels, must be > 0
- * @height: Height of the image in pixels, must be > 0
- * @rowstride: Distance in bytes between row starts
- * @destroy_fn: Function used to free the data when the pixbuf's reference count

- * @filename: name of file to save.
- * @type: name of file format.
- * @error: (allow-none): return location for error, or %NULL
- * @Varargs: list of key-value save options
- *
- * Saves pixbuf to a file in format @type. By default, "jpeg", "png", "ico"
- * and "bmp" are possible file formats to save in, but more formats may be
- * installed. The list of all writable formats can be determined in the
- * following way:
- *
- * |[
- * void add_if_writable (GdkPixbufFormat *data, GSList **list)
- * {
- * if (gdk_pixbuf_format_is_writable (data))
- * *list = g_slist_prepend (*list, data);

- * GSList *writable_formats = NULL;
- * g_slist_foreach (formats, add_if_writable, &writable_formats);
- * g_slist_free (formats);
- * ]|
- *
- * If @error is set, %FALSE will be returned. Possible errors include
- * those in the #GDK_PIXBUF_ERROR domain and those in the #G_FILE_ERROR domain.
- *
- * The variable argument list should be %NULL-terminated; if not empty,
- * it should contain pairs of strings that modify the save
- * parameters. For example:
- * <informalexample><programlisting>
- * gdk_pixbuf_save (pixbuf, handle, "jpeg", &error,
- * "quality", "100", NULL);
- * </programlisting></informalexample>
- *
- * Currently only few parameters exist. JPEG images can be saved with a
- * "quality" parameter; its value should be in the range [0,100].
- *
- * Text chunks can be attached to PNG images by specifying parameters of
- * the form "tEXt::key", where key is an ASCII string of length 1-79.
- * The values are UTF-8 encoded strings. The PNG compression level can
- * be specified using the "compression" parameter; it's value is in an
- * integer in the range of [0,9].
- *
- * ICC color profiles can also be embedded into PNG and TIFF images.
- * The "icc-profile" value should be the complete ICC profile encoded
- * into base64.
- *
- * <informalexample><programlisting>
- * gchar *contents;
- * gchar *contents_encode;
- * gsize length;
- * g_file_get_contents ("/home/hughsie/.color/icc/L225W.icm", &contents, &length, NULL);
- * contents_encode = g_base64_encode ((const guchar *) contents, length);
- * gdk_pixbuf_save (pixbuf, handle, "png", &error,
- * "icc-profile", contents_encode,
- * NULL);
- * </programlisting></informalexample>
- *
- * TIFF images recognize a "compression" option which acceps an integer value.
- * Among the codecs are 1 None, 2 Huffman, 5 LZW, 7 JPEG and 8 Deflate, see
- * the libtiff documentation and tiff.h for all supported codec values.
- *
- * ICO images can be saved in depth 16, 24, or 32, by using the "depth"
- * parameter. When the ICO saver is given "x_hot" and "y_hot" parameters,
- * it produces a CUR instead of an ICO.
- *
- * Return value: whether an error was set

- * gdk_pixbuf_new_from_inline:
- * @data_length: Length in bytes of the @data argument or -1 to
- * disable length checks
- * @data: Byte data containing a serialized #GdkPixdata structure
- * @copy_pixels: Whether to copy the pixel data, or use direct pointers
- * @data for the resulting pixbuf
- * @error: #GError return location, may be %NULL to ignore errors
- *
- * Create a #GdkPixbuf from a flat representation that is suitable for
- * storing as inline data in a program. This is useful if you want to
- * ship a program with images, but don't want to depend on any
- * external files.
- *
- * GTK+ ships with a program called <command>gdk-pixbuf-csource</command>
- * which allows for conversion of #GdkPixbufs into such a inline representation.
- * In almost all cases, you should pass the <option>--raw</option> flag to
- * <command>gdk-pixbuf-csource</command>. A sample invocation would be:
- *
- * <informalexample><programlisting>
- * gdk-pixbuf-csource --raw --name=myimage_inline myimage.png
- * </programlisting></informalexample>
- *
- * For the typical case where the inline pixbuf is read-only static data,
- * you don't need to copy the pixel data unless you intend to write to
- * it, so you can pass %FALSE for @copy_pixels. (If you pass
- * <option>--rle</option> to <command>gdk-pixbuf-csource</command>, a copy
- * will be made even if @copy_pixels is %FALSE, so using this option is
- * generally a bad idea.)
- *
- * If you create a pixbuf from const inline data compiled into your
- * program, it's probably safe to ignore errors and disable length checks,
- * since things will always succeed:
- * <informalexample><programlisting>
- * pixbuf = gdk_pixbuf_new_from_inline (-1, myimage_inline, FALSE, NULL);
- * </programlisting></informalexample>
- *
- * For non-const inline data, you could get out of memory. For untrusted
- * inline data located at runtime, you could have corrupt inline data in
- * addition.
- *
- * Return value: A newly-created #GdkPixbuf structure with a reference,
- * count of 1, or %NULL if an error occurred.

- * - The TGAFooter isn't present in all TGA files. In fact, there's an older

-General ideas of Pixops
-=======================
-
- - Gain speed by special-casing the common case, and using
- generic code to handle the uncommon case.
-
- - Most of the time in scaling an image is in the center;
- however code that can handle edges properly is slow
- because it needs to deal with the possibility of running
- off the edge. So make the fast case code only handle
- the centers, and use generic, slow, code for the edges,
-
-Structure of Pixops
-===================
-
-The code of pixops can roughly be grouped into four parts:
-
- - Filter computation functions
-
- - Functions for scaling or compositing lines and pixels
- using precomputed filters
-
- - pixops process, the central driver that iterates through
- the image calling pixel or line functions as necessary
-
- - Wrapper functions (pixops_scale/composite/composite_color)
- that compute the filter, chooses the line and pixel functions
- and then call pixops_processs with the filter, line,
- and pixel functions.
-
-
-pixops process is a pretty scary looking function:
-
-static void
-pixops_process (guchar *dest_buf,
- int render_x0,
- int render_y0,
- int render_x1,
- int render_y1,
- int dest_rowstride,
- int dest_channels,
- gboolean dest_has_alpha,
- const guchar *src_buf,
- int src_width,
- int src_height,
- int src_rowstride,
- int src_channels,
- gboolean src_has_alpha,
- double scale_x,
- double scale_y,
- int check_x,
- int check_y,
- int check_size,
- guint32 color1,
- guint32 color2,
- PixopsFilter *filter,
- PixopsLineFunc line_func,
- PixopsPixelFunc pixel_func)
-
-(Some of the arguments should be moved into structures. It's basically
-"all the arguments to pixops_composite_color plus three more") The
-arguments can be divided up into:
-
-
-Information about the destination buffer
-
- guchar *dest_buf, int dest_rowstride, int dest_channels, gboolean dest_has_alpha,
-
-Information about the source buffer
-
- guchar *src_buf, int src_rowstride, int src_channels, gboolean src_has_alpha,
- int src_width, int src_height,
-
-Information on how to scale the source buf and the region of the scaled source
-to render onto the destination buffer
-
- int render_x0, int render_y0, int render_x1, int render_y1
- double scale_x, double scale_y
-
-Information about a constant color or check pattern onto which to to composite
-
- int check_x, int check_y, int check_size, guint32 color1, guint32 color2
-
-Information precomputed to use during the scale operation
-
- PixopsFilter *filter, PixopsLineFunc line_func, OixopsPixelFunc pixel_func
-
-
-Filter computation
-==================
-
-The PixopsFilter structure looks like:
-
-struct _PixopsFilter
-{
- int *weights;
- int n_x;
- int n_y;
- double x_offset;
- double y_offset;
-};
-
-
-'weights' is an array of size:
-
- weights[SUBSAMPLE][SUBSAMPLE][n_x][n_y]
-
-SUBSAMPLE is a constant - currently 16 in pixops.c.
-
-
-In order to compute a scaled destination pixel we convolve
-an array of n_x by n_y source pixels with one of
-the SUBSAMPLE * SUBSAMPLE filter matrices stored
-in weights. The choice of filter matrix is determined
-by the fractional part of the source location.
-
-To compute dest[i,j] we do the following:
-
- x = i * scale_x + x_offset;
- y = i * scale_x + y_offset;
- x_int = floor(x)
- y_int = floor(y)
-
- C = weights[SUBSAMPLE*(x - x_int)][SUBSAMPLE*(y - y_int)]
- total = sum[l=0..n_x-1, j=0..n_y-1] (C[l,m] * src[x_int + l, x_int + m])
-
-The filter weights are integers scaled so that the total of the
-weights in the weights array is equal to 65536.
-
-When the source does not have alpha, we simply compute each channel
-as above, so total is in the range [0,255*65536]
-
- dest = src / 65536
-
-When the source does have alpha, then we need to compute using
-"pre-multiplied alpha":
-
- a_total = sum (C[l,m] * src_a[x_int + l, x_int + m])
- c_total = sum (C[l,m] * src_a[x_int + l, x_int + m] * src_c[x_int + l, x_int + m])
-
-This gives us a result for c_total in the range of [0,255*a_total]
-
- c_dest = c_total / a_total
-
-
-Mathematical aside:
-
-The process of producing a destination filter consists
-of:
-
- - Producing a continuous approximation to the source
- image via interpolation.
-
- - Sampling that continuous approximation with filter.
-
-This is representable as:
-
- S(x,y) = sum[i=-inf,inf; j=-inf,inf] A(frac(x),frac(y))[i,j] * S[floor(x)+i,floor(y)+j]
-
- D[i,j] = Integral(s=-inf,inf; t=-inf,inf) B(i+x,j+y) S((i+x)/scale_x,(i+y)/scale_y)
-
-By reordering the sums and integrals, you get something of the form:
-
- D[i,j] = sum[l=-inf,inf; m=-inf;inf] C[l,m] S[i+l,j+l]
-
-The arrays in weights are the C[l,m] above, and are thus
-determined by the interpolating algorithm in use and the
-sampling filter:
-
- INTERPOLATE SAMPLE
- ART_FILTER_NEAREST nearest neighbour point
- ART_FILTER_TILES nearest neighbour box
- ART_FILTER_BILINEAR (scale < 1) nearest neighbour box (scale < 1)
- ART_FILTER_BILINEAR (scale > 1) bilinear point (scale > 1)
- ART_FILTER_HYPER bilinear box
-
-
-Pixel Functions
-===============
-
-typedef void (*PixopsPixelFunc) (guchar *dest, int dest_x, int dest_channels, int dest_has_alpha,
- int src_has_alpha,
- int check_size, guint32 color1, guint32 color2,
- int r, int g, int b, int a);
-
-The arguments here are:
-
- dest: location to store the output pixel
- dest_x: x coordinate of destination (for handling checks)
- dest_has_alpha, dest_channels: Information about the destination pixbuf
- src_has_alpha: Information about the source pixbuf
-
- check_size, color1, color2: Information for color background for composite_color variant
-
- r,g,b,a - scaled red, green, blue and alpha
-
-r,g,b are premultiplied alpha.
-
- a is in [0,65536*255]
- r is in [0,255*a]
- g is in [0,255*a]
- b is in [0,255*a]
-
-If src_has_alpha is false, then a will be 65536*255, allowing optimization.
-
-
-Line functions
-==============
-
-typedef guchar *(*PixopsLineFunc) (int *weights, int n_x, int n_y,
- guchar *dest, int dest_x, guchar *dest_end, int dest_channels, int dest_has_alpha,
- guchar **src, int src_channels, gboolean src_has_alpha,
- int x_init, int x_step, int src_width,
- int check_size, guint32 color1, guint32 color2);
-
-The argumets are:
-
- weights, n_x, n_y
-
- Filter weights for this row - dimensions weights[SUBSAMPLE][n_x][n_y]
-
- dest, dest_x, dest_end, dest_channels, dest_has_alpha
-
- The destination buffer, function will start writing into *dest and
- increment by dest_channels, until dest == dest_end. Reading from
- src for these pixels is guaranteed not to go outside of the
- bufer bounds
-
- src, src_channels, src_has_alpha
-
- src[n_y] - an array of pointers to the start of the source rows
- for each filter coordinate.
-
- x_init, x_step
-
- Information about x positions in source image.
-
- src_width - unused
-
- check_size, color1, color2: Information for color background for composite_color variant
-
- The total for the destination pixel at dest + i is given by
-
- SUM (l=0..n_x - 1, m=0..n_y - 1)
- src[m][(x_init + i * x_step)>> SCALE_SHIFT + l] * weights[m][l]
-
-
-Algorithms for compositing
-==========================
-
-Compositing alpha on non alpha:
-
- R = As * Rs + (1 - As) * Rd
- G = As * Gs + (1 - As) * Gd
- B = As * Bs + (1 - As) * Bd
-
-This can be regrouped as:
-
- Cd + Cs * (Cs - Rd)
-
-Compositing alpha on alpha:
-
- A = As + (1 - As) * Ad
- R = (As * Rs + (1 - As) * Rd * Ad) / A
- G = (As * Gs + (1 - As) * Gd * Ad) / A
- B = (As * Bs + (1 - As) * Bd * Ad) / A
-
-The way to think of this is in terms of the "area":
-
-The final pixel is composed of area As of the source pixel
-and (1 - As) * Ad of the target pixel. So the final pixel
-is a weighted average with those weights.
-
-Note that the weights do not add up to one - hence the
-non-constant division.
-
-
-Integer tricks for compositing
-==============================
-
-
-
-MMX Code
-========
-
-Line functions are provided in MMX functionsfor a few special
-cases:
-
- n_x = n_y = 2
-
- src_channels = 3 dest_channels = 3 op = scale
- src_channels = 4 with alpha dest_channels = 4 no alpha op = composite
- src_channels = 4 with alpha dest_channels = 4 no alpha op = composite_color
-
-For the case n_x = n_y = 2 - primarily hit when scaling up with bilinear
-scaling, we can take advantage of the fact that multiple destination
-pixels will be composed from the same source pixels.
-
-That is a destination pixel is a linear combination of the source
-pixels around it:
-
-
- S0 S1
-
-
-
-
-
- D D' D'' ...
-
-
-
-
- S2 S3
-
-Each mmx register is 64 bits wide, so we can unpack a source pixel
-into the low 8 bits of 4 16 bit words, and store it into a mmx
-register.
-
-For each destination pixel, we first make sure that we have pixels S0
-... S3 loaded into registers mm0 ...mm3. (This will often involve not
-doing anything or moving mm1 and mm3 into mm0 and mm1 then reloading
-mm1 and mm3 with new values).
-
-Then we load up the appropriate weights for the 4 corner pixels
-based on the offsets of the destination pixel within the source
-pixels.
-
-We have preexpanded the weights to 64 bits wide and truncated the
-range to 8 bits, so an original filter value of
-
- 0x5321 would be expanded to
-
- 0x0053005300530053
-
-For source buffers without alpha, we simply do a multiply-add
-of the weights, giving us a 16 bit quantity for the result
-that we shift left by 8 and store in the destination buffer.
-
-When the source buffer has alpha, then things become more
-complicated - when we load up mm0 and mm3, we premultiply
-the alpha, so they contain:
-
- (a*ff >> 8) (r*a >> 8) (g*a >> 8) (b*a >> a)
-
-Then when we multiply by the weights, and add we end up
-with premultiplied r,g,b,a in the range of 0 .. 0xff * 0ff,
-call them A,R,G,B
-
-We then need to composite with the dest pixels - which
-we do by:
-
- r_dest = (R + ((0xff * 0xff - A) >> 8) * r_dest) >> 8
-
-(0xff * 0xff)

-PRINCIPLES
-==========
-
-The general principle of this code is that it first computes a filter
-matrix for the given filtering mode, and then calls a general driver
-routine, passing in functions to composite pixels and lines.
-
-(The pixel functions are used for handling edge cases, and the line
-functions are simply used for the middle parts of the image.)
-
-The system is designed so that the line functions can be simple,
-don't have to worry about special cases, can be selected to
-be specific to the particular formats involved. This allows them
-to be hyper-optimized. Since most of the compution time is
-spent in these functions, this results in an overall fast design.
-
-MMX assembly code for Intel (and compatible) processors is included
-for a number of the most common special cases:
-
- scaling from RGB to RGB
- compositing from RGBA to RGBx
- compositing against a color from RGBA and storing in a RGBx buffer
-
-Alpha compositing 8 bit RGBAa onto RGB is defined in terms of
-rounding the exact result (real values in [0,1]):
-
- cc = ca * aa + (1 - aa) * Cb
-
- Cc = ROUND [255. * (Ca/255. * Aa/255. + (1 - Aa/255.) * Cb/255.)]
-
-ROUND(i / 255.) can be computed exactly for i in [0,255*255] as:
-
- t = i + 0x80; result = (t + (t >> 8)) >> 8; [ call this as To8(i) ]
-
-So,
-
- t = Ca * Aa + (255 - Aa) * Cb + 0x80;
- Cc = (t + (t >> 8)) >> 8;

-Alpha compositing 8 bit RaGaBaAa onto RbGbBbAa is a little harder, for
-non-premultiplied alpha. The premultiplied result is simple:
-
- ac = aa + (1 - aa) * ab
- cc = ca + (1 - aa) * cb
-
-Which can be computed in integers terms as:
-
- Cc = Ca + To8 ((255 - Aa) * Cb)
- Ac = Aa + To8 ((255 - Aa) * Ab)
-
-For non-premultiplied alpha, we need divide the color components by
-the alpha:
-
- +- (ca * aa + (1 - aa) * ab * cb)) / ac; aa != 0
- cc = |
- +- cb; aa == 0
-
-To calculate this as in integer, we note the alternate form:
-
- cc = cb + aa * (ca - cb) / ac
-
-[ 'cc = ca + (ac - aa) * (cb - ca) / ac' can also be useful numerically,
- but isn't important here ]
-
-We can express this as integers as:
-
- Ac_tmp = Aa * 255 + (255 - Aa) * Ab;
-
- +- Cb + (255 * Aa * (Ca - Cb) + Ac_tmp / 2) / Ac_tmp ; Ca > Cb
- Cc = |
- +- Cb - (255 * Aa * (Cb - Ca) + Ac_tmp / 2) / Ac_tmp ; ca <= Cb
-
-Or, playing bit tricks to avoid the conditional
-
- Cc = Cb + (255 * Aa * (Ca - Cb) + (((Ca - Cb) >> 8) ^ (Ac_tmp / 2)) ) / Ac_tmp
-
-TODO
-====
-
-* ART_FILTER_HYPER is not correctly implemented. It is currently
- implemented as a filter that is derived by doing linear interpolation
- on the source image and then averaging that with a box filter.
-
- It should be defined as followed (see art_filterlevel.h)
-
- "HYPER is the highest quality reconstruction function. It is derived
- from the hyperbolic filters in Wolberg's "Digital Image Warping,"
- and is formally defined as the hyperbolic-filter sampling the ideal
- hyperbolic-filter interpolated image (the filter is designed to be
- idempotent for 1:1 pixel mapping). It is the slowest and highest
- quality."
-
- The current HYPER is probably as slow, but lower quality. Also, there
- are some subtle errors in the calculation current HYPER that show up as dark
- stripes if you scale a constant-color image.
-
-* There are some roundoff errors in the compositing routines.
- the _nearest() variants do it right, most of the other code
- is wrong to some degree or another.
-
- For instance, in composite_line_22_4a4(), we have:
-
- dest[0] = ((0xff0000 - a) * dest[0] + r) >> 24;
-
- if a is 0 (implies r == 0), then we have:
-
- (0xff0000 * dest[0]) >> 24
-
- which gives results which are 1 to low:
-
- 255 => 254, 1 => 0.
-
- So, this should be something like:
-
- ((0xff0000 - a) * dest[0] + r + 0xffffff) >> 24;
-
- (Not checked, caveat emptor)
-
- An alternatve formulation of this as:
-
- dest[0] + (r - a * dest[0] + 0xffffff) >> 24
-
- may be better numerically, but would need consideration for overflow.
-
-* The generic functions could be sped up considerably by
- switching around conditionals and inner loops in various
- places.
-
-* Right now, in several of the most common cases, there are
- optimized mmx routines, but no optimized C routines.
-
- For instance, there is a
-
- pixops_composite_line_22_4a4_mmx()
-
- But no
-
- pixops_composite_line_22_4a4()
-
- Also, it may be desirable to include a few more special cases - in particular:
-
- pixops_composite_line_22_4a3()
-
- May be desirable.
-
-* Scaling down images by large scale factors is _slow_ since huge filter
- matrixes are computed. (e.g., to scale down by a factor of 100, we compute
- 101x101 filter matrixes. At some point, it would be more efficent to
- switch over to subsampling when scaling down - one should never need a filter
- matrix bigger than 16x16.

-\title{Some image transform math}
-\author{Owen Taylor}
-\date{18 February 2003}
-\maketitle
-
-\section{Basics}
-
-The transform process is composed of three steps;
-first we reconstruct a continuous image from the
-source data \(A_{i,j}\):
-\[a(u,v) = \sum_{i = -\infty}^{\infty} \sum_{j = -\infty}^{\infty} A_{i,j}F\left( {u - i \atop v - j} \right) \]
-Then we transform from destination coordinates to source coordinates:
-\[b(x,y) = a\left(u(x,y) \atop v(x,y)\right)
- = a\left(t_{00}x + t_{01}y + t_{02} \atop t_{10}x + t_{11}y + t_{12} \right)\]
-Finally, we resample using a sampling function \(G\):
-\[B_{x_0,y_0} = \int_{-\infty}^{\infty}\int_{-\infty}^{\infty} b(x,y)G\left( {x - x_0 \atop y - y_0} \right) dxdy\]
-Putting all of these together:
-\[B_{x_0,y_0} =
-\int_{-\infty}^{\infty}\int_{-\infty}^{\infty}
-\sum_{i = -\infty}^{\infty} \sum_{j = -\infty}^{\infty} A_{i,j}
-F\left( {u(x,y) - i \atop v(x,y) - j} \right)
-G\left( {x - x_0 \atop y - y_0} \right) dxdy\]
-We can reverse the order of the integrals and the sums:
-\[B_{x_0,y_0} =
-\sum_{i = -\infty}^{\infty} \sum_{j = -\infty}^{\infty} A_{i,j}
-\int_{-\infty}^{\infty}\int_{-\infty}^{\infty}
-F\left( {u(x,y) - i \atop v(x,y) - j} \right)
-G\left( {x - x_0 \atop y - y_0} \right) dxdy\]
-Which shows that the destination pixel values are a linear combination of the
-source pixel values. But the coefficents depend on \(x_0\) and \(y_0\).
-To simplify this a bit, define:
-\[i_0 = \lfloor u(x_0,y_0) \rfloor = \lfloor {t_{00}x_0 + t_{01}y_0 + t_{02}} \rfloor \]
-\[j_0 = \lfloor v(x_0,y_0) \rfloor = \lfloor {t_{10}x_0 + t_{11}y_0 + t_{12}} \rfloor \]
-\[\Delta_u = u(x_0,y_0) - i_0 = t_{00}x_0 + t_{01}y_0 + t_{02} - \lfloor {t_{00}x_0 + t_{01}y_0 + t_{02}} \rfloor \]
-\[\Delta_v = v(x_0,y_0) - j_0 = t_{10}x_0 + t_{11}y_0 + t_{12} - \lfloor {t_{10}x_0 + t_{11}y_0 + t_{12}} \rfloor \]
-Then making the transforms \(x' = x - x_0\), \(y' = y - x_0\), \(i' = i - i_0\), \(j' = j - x_0\)
-\begin{eqnarray*}
-F(u,v) & = & F\left( {t_{00}x + t_{01}y + t_{02} - i \atop t_{10}x + t_{11}y + t_{12} - j} \right)\\
- & = & F\left( {t_{00}(x'+x_0) + t_{01}(y'+y_0) + t_{02} - (i'+i_0) \atop
- t_{10}(x'+x_0) + t_{11}(y'+y_0) + t_{12} - (j'+j_0)} \right) \\
- & = & F\left( {\Delta_u + t_{00}x' + t_{01}y' - i' \atop
- \Delta_v + t_{10}x' + t_{11}y' - j'} \right)
-\end{eqnarray*}
-Using that, we can then reparameterize the sums and integrals and
-define coefficients that depend only on \((\Delta_u,\Delta_v)\),
-which we'll call the \emph{phase} at the point \((x_0,y_0)\):
-\[
-B_{x_0,y_0} =
-\sum_{i = -\infty}^{\infty} \sum_{j = -\infty}^{\infty} A_{i_0+i,j_0+j} C_{i,j}(\Delta_u,\Delta_v)
-\]
-\[
-C_{i,j}(\Delta_u,\Delta_v) =
-\int_{-\infty}^{\infty}\int_{-\infty}^{\infty}
-F\left( {\Delta_u + t_{00}x + t_{01}y - i \atop
- \Delta_v + t_{10}x + t_{11}y - j} \right)
-G\left( {x \atop y} \right) dxdy
-\]
-\section{Separability}
-A frequent special case is when the reconstruction and sampling functions
-are of the form:
-\[F(u,v) = f(u)f(v)\]
-\[G(x,y) = g(x)g(y)\]
-If we also have a transform that is purely a scale and translation;
-(\(t_{10} = 0\), \(t_{01} = 0\)), then we can separate
-\(C_{i,j}(\Delta_u,\Delta_v)\) into the product of a \(x\) portion
-and a \(y\) portion:
-\[C_{i,j}(\Delta_u,\Delta_v) = c_{i}(\Delta_u) c_{j}(\Delta_v)\]
-\[c_{i}(\Delta_u) = \int_{-\infty}^{\infty} f(\Delta_u + t_{00}x - i)g(x)dx\]
-\[c_{j}(\Delta_v) = \int_{-\infty}^{\infty} f(\Delta_v + t_{11}y - j)g(y)dy\]
-
-\section{Some filters}
-gdk-pixbuf provides 4 standard filters for scaling, under the names ``NEAREST'',
-``TILES'', ``BILINEAR'', and ``HYPER''. All of turn out to be separable
-as discussed in the previous section.
-For ``NEAREST'' filter, the reconstruction function is simple replication
-and the sampling function is a delta function\footnote{A delta function is an infinitely narrow spike, such that:
-\[\int_{-\infty}^{\infty}\delta(x)f(x) = f(0)\]}:
-\[f(t) = \cases{1, & if \(0 \le t \le 1\); \cr
- 0, & otherwise}\]
-\[g(t) = \delta(t - 0.5)\]
-For ``TILES'', the reconstruction function is again replication, but we
-replace the delta-function for sampling with a box filter:
-\[f(t) = \cases{1, & if \(0 \le t \le 1\); \cr
- 0, & otherwise}\]
-\[g(t) = \cases{1, & if \(0 \le t \le 1\); \cr
- 0, & otherwise}\]
-The ``HYPER'' filter (in practice, it was originally intended to be
-something else) uses bilinear interpolation for reconstruction and
-a box filter for sampling:
-\[f(t) = \cases{1 - |t - 0.5|, & if \(-0.5 \le t \le 1.5\); \cr
- 0, & otherwise}\]
-\[g(t) = \cases{1, & if \(0 \le t \le 1\); \cr
- 0, & otherwise}\]
-The ``BILINEAR'' filter is defined in a somewhat more complicated way;
-the definition depends on the scale factor in the transform (\(t_{00}\)
-or \(t_{01}]\). In the \(x\) direction, for \(t_{00} < 1\), it is
-the same as for ``TILES'':
-\[f_u(t) = \cases{1, & if \(0 \le t \le 1\); \cr
- 0, & otherwise}\]
-\[g_u(t) = \cases{1, & if \(0 \le t \le 1\); \cr
- 0, & otherwise}\]
-but for \(t_{10} > 1\), we use bilinear reconstruction and delta-function
-sampling:
-\[f_u(t) = \cases{1 - |t - 0.5|, & if \(-0.5 \le t \le 1.5\); \cr
- 0, & otherwise}\]
-\[g_u(t) = \delta(t - 0.5)\]
-The behavior in the \(y\) direction depends in the same way on \(t_{11}\).
