1 2001-05-08 Havoc Pennington <hp@redhat.com>
3 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
4 and fix behavior to still subst color if the original image
7 2001-06-04 Havoc Pennington <hp@redhat.com>
9 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
12 2001-06-01 Havoc Pennington <hp@redhat.com>
14 Apply patch from sandmann@daimi.au.dk, with some tweaks.
15 Makes things a bit more robust, and adds test-loaders.c
16 which is good for finding further robustness bugs to fix.
18 * io-tiff.c: Try to work around libtiff suckiness a bit;
19 put a giant thread lock on the whole loader,
20 paranoically check both whether error handlers were called and
21 also whether functions return false. Handle case where width or
22 height is 0. Various cleanups.
24 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
26 (png_error_callback): apparently libpng expects you to longjmp out
29 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
30 (lzw_read_byte): change "Mail jrb if this fails" g_warning
32 (gif_get_lzw): check for out-of-memory
33 (gif_prepare_lzw): catch/report an error
34 (new_context): use try_malloc, since GifContext is nearly 70K
35 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
36 so we don't crash later.
38 * Makefile.am: Add test-loaders
40 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
43 2001-05-29 Darin Adler <darin@eazel.com>
45 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
47 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
49 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
50 fix up bmp decoder to:
51 - adds 16 bpp bmp support (bug #53884)
52 - adds OS/2 1.x format bmp support (bug #54964)
53 - adds 4 bpp RLE compressed bmp support
54 - adds 1 bpp colormap support
55 - fixes negative height (top down) bmp support
57 2001-05-25 Hans Breuer <hans@breuer.org>
59 * gdk_pixbuf.def : reflect Havoc's recent api change
61 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
63 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
66 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
68 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
70 2001-05-04 Havoc Pennington <hp@redhat.com>
72 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
73 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
76 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
77 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
78 confusion of using "src" instead of "p".
79 (pixops_composite_color_nearest): Use a more accurate (and
80 correct, to begin with) compositing method. This cures checks
81 showing through on images with no alpha.
83 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
86 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
88 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
89 area_updated signal to use signed ints. Removed animation-related
92 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
95 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
96 all the pesky details. Remove old frame-based API. Make
97 GdkPixbufAnimation an abstract base class, derived by the loaders.
99 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
101 * Makefile.am (LDADDS): Add $(MATH_LIB).
103 2001-04-18 Havoc Pennington <hp@redhat.com>
105 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
108 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
110 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
111 so we don't try to get <gtk/gtkobject.h> from standard search
114 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
115 add gdk-pixbuf-marshal.list to EXTRA_DIST.
116 take gdk-pixbuf-marshal.h out of _la sources.
118 2001-03-19 Tor Lillqvist <tml@iki.fi>
120 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
122 * gdk_pixbuf.def: Update.
124 * pixbufloader_*.def: Just export the fill_vtable functions now.
126 2001-03-18 Mike Kestner <mkestner@ameritech.net>
128 * make-inline-pixbuf.c (main): Added logic to remove output when
131 2001-03-14 Havoc Pennington <hp@redhat.com>
133 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
134 from gdk-pixbuf-marshal.h, fixes parallel makes.
136 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
138 * test-gdk-pixbuf.c: fixed includes.
140 2001-02-18 Havoc Pennington <hp@pobox.com>
142 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
143 (gdk_pixbuf_get_named_module): prepend underscore
144 (gdk_pixbuf_get_module): prepend underscore
146 2001-02-19 Havoc Pennington <hp@redhat.com>
148 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
150 2001-02-17 Havoc Pennington <hp@pobox.com>
152 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
154 2001-02-07 Alexander Larsson <alexl@redhat.com>
156 * io-xpm.c (free_buffer):
157 Use g_free, since the buffer is allocated with g_try_alloc().
159 2001-02-06 Christophe Merlet <redfox@eikonex.org>
161 * gdk-pixbuf-data.c: Fixes a minor typo.
163 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
165 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
166 we finally need the gobject->gruntime rename.
168 * *.c: scratched calls to g_type_init(), there's simply no point in
169 doing that, use gtk_init().
171 2001-02-01 Havoc Pennington <hp@pobox.com>
173 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
174 in struct to "priv" for C++
176 2001-01-31 Havoc Pennington <hp@pobox.com>
178 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
180 2001-01-26 Havoc Pennington <hp@redhat.com>
182 * gdk-pixbuf-io.c (mname): fix included modules case.
184 2001-01-22 Havoc Pennington <hp@redhat.com>
186 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
187 from gdk_pixbuf_load_module
189 2001-01-22 Havoc Pennington <hp@redhat.com>
191 * Makefile.am: Add built marshaller files to support
192 GdkPixbufLoader signals
194 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
195 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
196 module location, rather than acting as a fallback, because we are
197 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
199 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
201 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
202 from gtk, and add error to close(), because stop_load may do
203 parsing of the image.
205 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
207 * io-*.c: make individual operations static, and add fill_vtable
208 functions which are exported. Fix the collection of type warnings
209 that surfaced, including a number of functions that didn't
210 properly take a GError and some that weren't
211 const-correct. Involved adding error handling for a few loaders.
213 * gdk-pixbuf-io.h: Add error reporting to stop_load function
215 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
216 a function that fills in the GdkPixbufModule vtable, instead of
217 looking up all the image functions individually; this means we
218 can get type safety within modules for the loader functions.
219 Also it means you don't have to keep the statically compiled and
220 GModule versions in sync.
222 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
224 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
226 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
228 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
231 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
233 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
236 2001-01-20 John Harper <jsh@eazel.com>
238 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
239 collision between Xlib's RdBitF.c and io-tiff.c
241 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
244 [ merged from stable gdk-pixbuf module. Untested, but it
245 compiles, and works fine in the stable module ]
247 2001-01-18 Tor Lillqvist <tml@iki.fi>
249 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
250 g_win32_get_package_installation_subdirectory() function. No need
251 to include windows.h.
252 (gtk_win32_get_installation_directory): Remove this then.
254 2001-01-01 Havoc Pennington <hp@redhat.com>
256 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
257 @LIBTOOL_EXPORT_OPTIONS@
259 2000-12-30 Tor Lillqvist <tml@iki.fi>
261 * gdk_pixbuf.def: Update.
263 2000-12-16 Havoc Pennington <hp@pobox.com>
265 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
266 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
267 (gdk_pixbuf_frame_copy): new function
268 (gdk_pixbuf_frame_free): new function
269 (gdk_pixbuf_frame_get_type): new function
270 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
272 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
274 * Makefile.am: Add -avoid-version for all modules.
276 2000-11-13 Havoc Pennington <hp@redhat.com>
278 * io-png.c (png_simple_error_callback): fix error message to not
279 say "save" since it's used for loading
281 2000-11-11 Hans Breuer <Hans@Breuer.Org>
283 * gdk-pixbuf-io.c : Fix all function prototype macros for self
284 contained image handlers (!USE_G_MODULE). Files to save should
285 be opened in binary mode, fopen(s, "wb").
287 * io-xpm.c : added HAVE_UNISTD_H condition
289 2000-11-11 Tor Lillqvist <tml@iki.fi>
291 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
293 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
294 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
295 mktemp() and open()).
297 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
299 2000-11-01 Havoc Pennington <hp@pobox.com>
301 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
302 a pixbuf pointing to a subregion of another pixbuf.
304 2000-10-16 Tor Lillqvist <tml@iki.fi>
306 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
308 2000-10-16 Havoc Pennington <hp@redhat.com>
310 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
311 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
312 add error reporting here also
314 * make-inline-pixbuf.c (main): use GError
316 * io-xpm.c: include unistd.h
318 * gdk-pixbuf-util.c: include string.h
320 * io-*.c: add error reporting
322 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
325 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
327 * gdk-pixbuf-io.h: Add GError** to load_increment and load
330 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
331 a G_FILE_ERROR if we fail to write or close the file.
333 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
334 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
335 the GError naming rules. Add GError** to load functions.
337 2000-10-06 Havoc Pennington <hp@redhat.com>
339 * gdk-pixbuf.h: add GdkPixbufAlphaMode
341 2000-10-06 Havoc Pennington <hp@redhat.com>

369 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
371 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
372 last nights code was still "broken". Should now properly handle
373 all error conditions gracefully.
375 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
377 * gdk-pixbuf/io-pnm.c: Rewrote.
379 2000-09-09 Federico Mena Quintero <federico@helixcode.com>
381 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
382 the correct dest offset.

386 * gdk-pixbuf/io-xpm.c: #include <unistd.h>
388 2000-08-05 Larry Ewing <lewing@helixcode.com>
390 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
392 * gdk-pixbuf/io-xpm.c: same as above.
394 2000-07-26 Michael Meeks <michael@helixcode.com>
396 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
399 2000-07-21 Larry Ewing <lewing@helixcode.com>
401 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
402 xpm at least supports the progressive interface like the one in
403 io-tiff.c. This should be reimplemented as an actual progressive
406 2000-07-19 Jonathan Blandford <jrb@redhat.com>
408 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
410 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
411 meeks to handle errors better.
413 2000-10-07 Tor Lillqvist <tml@iki.fi>

421 2000-10-06 Havoc Pennington <hp@redhat.com>
423 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
424 consistent with gdk_pixbuf_loader_new_with_type().
425 Return runtime error if a module is missing.
427 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
429 2000-10-05 Havoc Pennington <hp@redhat.com>
431 Pixbuf saving, patch from David Welton.
433 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
434 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
436 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf

442 * gdk-pixbuf-io.c (gdk_pixbuf_save):
443 (gdk_pixbuf_savev): Implement pixbuf saving routines
445 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
448 * gdk-pixbuf.h: Add public save routines; add pixbuf error

453 2000-10-05 Dan Winship <danw@helixcode.com>
455 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
456 all three of these files are the JPEG image loader. (From
459 2000-10-03 Tor Lillqvist <tml@iki.fi>
461 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
462 gdk-pixbuf's version number in the rule for makefile.mingw itself.
464 * gdk_pixbuf.def: Add new entry points.
466 2000-09-26 Havoc Pennington <hp@redhat.com>
468 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
469 function here, instead of putting it in a private GTK+ file.
471 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
472 enum here for the known formats of inlined pixbufs.
473 Also, #define our file magic here.
475 2000-06-23 Havoc Pennington <hp@redhat.com>
477 * make-inline-pixbuf.c: Small program that creates C variable
478 declarations of inline pixbuf data. This can be read
479 by gdk_pixbuf_new_from_inline.
481 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
482 inline pixbuf data and create a pixbuf from it.
484 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
486 2000-09-07 Tor Lillqvist <tml@iki.fi>
488 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
491 2000-08-12 Tor Lillqvist <tml@iki.fi>
493 * gdk_pixbuf.def: Add missing entry point.
495 2000-08-10 Havoc Pennington <hp@redhat.com>
497 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
498 (s/pixbuf_/pixbufloader_)
500 2000-08-02 Tor Lillqvist <tml@iki.fi>
506 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
508 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
509 one. Fix names of DLLs to have '-' instead of '_'.
511 2000-07-31 Elliot Lee <sopwith@redhat.com>
512 * io-wbmp.c: Some bug fixes - now tested to work.
514 2000-07-27 Elliot Lee <sopwith@redhat.com>
516 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
517 gdk_pixbuf_get_named_module() function to facilitate above change
518 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
519 Implement loader for WBMP format.
520 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
522 2000-07-23 Tor Lillqvist <tml@iki.fi>
527 * pixops/makefile.mingw.in
528 * pixbuf_*.def: New files.
531 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
533 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
534 New function, to get the GTK+ installation directory from
535 the Windows Registry, where the installation program
536 for whatever software includes GTK+ has stored it.
538 Used to avoid having hardcoding the directory where to look for
539 loaders. This function is needed by gtk, too, so it should
540 really be just in one place. Maybe a small static library
541 one level up from here?
543 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
544 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
545 Open file in binary mode. This *is* standard C. (No-op on Unix,
548 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
550 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
552 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
554 * pixops/*.S: The Gas from mingw32 doesn't like the .type
555 pseudo-op. Conditionalise on __MINGW32__, but probably
556 should conditionalise on Gas version instead? Or could we
557 do without .type on all systems?
559 * pixops/timescale.c: Use g_get_current_time()
560 instead of gettimeofday().
562 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
564 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
566 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
568 * gdk-pixbuf.c: Add <string.h> include.
570 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
572 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
573 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
574 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
575 use g_object_new() instead of g_type_create_instance() which
576 is a private function for fundamental type implementations.
578 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
580 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
581 soname scheme for gdk-pixbuf.
583 2000-06-21 Havoc Pennington <hp@pobox.com>
585 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
586 (i.e. derivation is not allowed, and there are no virtual methods
588 (gdk_pixbuf_preinit): Call g_type_init() here.
589 (gdk_pixbuf_init): Add a user-friendly init function, for users
590 of standalone gdk-pixbuf
592 * gdk-pixbuf-animation.c: Convert to GObject, in the same
593 way GdkPixbufAnimation was done.
595 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
596 gdk_pixbuf_finalize() from API, since these are broken and don't
597 make sense with new GObject stuff.
599 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
601 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
602 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
605 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
607 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
608 so I needed something to warm my thighs. Running plain infinite
609 loops on your laptop to make it hot is not very much fun. A demo
610 of the gdk-pixbuf scaling functions is way better, and looks
613 * configure.in (AC_OUTPUT): Added the demo Makefile.
615 * Makefile.am (SUBDIRS): Added the demo directory.
617 2000-06-09 Larry Ewing <lewing@helixcode.com>
619 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
620 setjmp for the png error handler. It seems setting the error
621 handling functions does not avoid the jump, and so not calling
622 setjmp was causing the incremental loader to jump into lala land.
623 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
624 not sure this one is actually required but the docs say it must be
625 set for every call to a png_* function.
626 Also changed the comment to reflect the fact that setting the
627 error handlers does _not_ avoid the longjmp.
629 2000-06-06 Larry Ewing <lewing@helixcode.com>
631 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
632 take frame offest into account when trying to calculate the
633 animation bbox. Also set the width to the width not the height.
634 (gdk_pixbuf_loader_animation_done): cycle over the frames to
635 calculate bbox because now we finally have all the offset
636 information for each frame.
638 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
640 * configure.in: add some gtk parameters to the
641 GDK_PIXBUF_LIB²S and GDK_PIXBUG_INCLUDEDIR vars. One more
642 fight in my crusade for strange prefix compile...
644 2000-05-30 Not Zed <NotZed@HelixCode.com>
646 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
647 Initialise the error handler exit routine to our own. Note this
648 means that every function that accesses the jpeg lib on this
649 object MUST do a setjmp.
650 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
651 lib for handling fatal error.
652 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
653 your applications dont quit if there's a jpeg error!
655 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
657 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
658 from Frank de Lange <frank@unternet.org>.
660 2000-05-09 Darin Adler <darin@eazel.com>
662 * gdk-pixbuf/test-gdk-pixbuf.c:
663 Fixed includes to get rid of accidental GNOME dependency.
665 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
666 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
668 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
670 * configure.in: Bumped version number to 0.8.0.
672 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
673 file was not being distributed.
675 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
677 2000-05-09 Darin Adler <darin@eazel.com>
679 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
680 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
681 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
682 formats to 32-bit formats to re-use the high bits of the color values
683 so that white maps to full white.
685 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
687 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
688 detailed information about the structure and algorithms
689 of pixops so people can fix it instead of breaking it.
691 2000-05-04 Darin Adler <darin@eazel.com>
693 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
694 (composite_pixel), (composite_line):
695 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
696 Now that Owen explained the algorithm, I think I implemented it
697 right for the cases where the destination pixbuf is not opaque.
698 The test does seem to confirm it.
700 2000-05-04 Darin Adler <darin@eazel.com>
702 * gdk-pixbuf/.cvsignore:
703 * gdk-pixbuf/Makefile.am:
704 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
705 (load_pixel), (simple_composite_test_one),
706 (simple_composite_test_one_type), (simple_composite_test), (main):
707 Added some tests of composite to highlight problems in the old
708 implementation. These tests run without any user interaction.
709 Just do "make check".
711 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
712 (composite_pixel), (composite_line): Fix composite to do a textbook
713 "A over B" composite. This was clearly the intent, and it was easy
714 to fix the code to do it. (Note to those that read my earlier tries
715 at a patch; this version fixes typos that were present in all
716 my patch attempts. I checked the final version by adding more tests.)
718 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
720 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
721 offset y coordinate accordining to render_y0.
723 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
726 2000-04-22 James Henstridge <james@daa.com.au>
728 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
729 package to the devel package. The only file installed in bin is
730 gdk-pixbuf-config, which belongs in -devel. This should allow having
731 multiple versions of the main gdk-pixbuf package installed.
733 2000-04-17 Karl Eichwalder <ke@suse.de>
735 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
736 Reported by Jens Finke.
738 2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
740 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
741 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
743 2000-04-13 James Henstridge <james@daa.com.au>
745 * configure.in: when performing the configure check to see if
746 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
747 rather than the other way round. Also, call AC_MSG_RESULT in the
748 even that dynamic modules were not supported.
750 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
752 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
753 hook to the last unref operation.
755 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
756 function to set the last unref handler for a pixbuf.
757 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
758 It calls the pixbuf's destroy notification function and frees the
759 GdkPixbuf structure itself.
760 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
763 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
764 for the last unref handler and its user data.
766 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
767 g_new0() to allocate the pixbuf.
769 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
770 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
771 was not specifying the `frame' argument.
773 * gdk-pixbuf/gdk-pixbuf-animation.c
774 (gdk_pixbuf_animation_get_width): Fixed docstring.
775 (gdk_pixbuf_animation_get_height): Likewise.
776 (gdk_pixbuf_animation_get_num_frames): Likewise.
777 (gdk_pixbuf_animation_get_frames): Likewise.
779 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
782 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
784 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
786 * doc/tmpl/refcounting.sgml: Updated with the information about
787 the last unref handler.
789 * doc/tmpl/*.sgml: Markup tweaks.
791 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
792 update the libtool version number for libgnomecanvaspixbuf as
794 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
795 as well, or the old ones won't work with the new stuff. Also,
796 renamed the modules as follows.
798 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
799 modules are called "libpixbufloader-<format>.so" instead of
800 "libpixbuf-<format>.so". They needed renaming so that the new
801 loaders won't overwrite the old ones; even with the versioning
802 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
805 2000-04-12 Paolo Molaro <lupus@debian.org>
807 * .cvsignore, src/.cvsignore: shut up cvs.
809 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
811 Most of this patch is based on a patch by Havoc Pennington
812 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
813 remove the libart dependency.
815 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
816 (GdkColorspace): New enum that for now only contains
818 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
819 notification function.
820 (GdkInterpType): New num with interpolation types.
822 * *.[ch]: Replace the libart stuff with our own stuff.
824 * pixops/*.[ch]: Likewise.
826 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
827 declarations of the GdkPixbuf structures.
829 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
831 (gdk_pixbuf_get_format): Constify.
832 (gdk_pixbuf_get_n_channels): Constify.
833 (gdk_pixbuf_get_has_alpha): Constify.

840 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
843 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
844 bits_per_sample argument; currently only 8 bits per sample are
847 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
849 (gdk_pixbuf_frame_get_x_offset): New accessor.
850 (gdk_pixbuf_frame_get_y_offset): New accessor.
851 (gdk_pixbuf_frame_get_delay_time): New accessor.
852 (gdk_pixbuf_frame_get_action): New accessor.
854 * gdk-pixbuf/gdk-pixbuf-render.c
855 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
856 mask rectangle for pixbufs without an alpha channel, set the
857 *mask_return to NULL.
859 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
861 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
863 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
864 preconditions. Maybe we should also check for the colorspace,
865 bits per pixel, and such.
866 (gdk_pixbuf_composite): Likewise.
867 (gdk_pixbuf_composite_color): Likewise.
868 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
869 cannot allocate the new pixbuf.
870 (gdk_pixbuf_composite_color_simple): Likewise.
872 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
873 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
876 * gdk-pixbuf/io-bmp.c: Fix includes.
878 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
883 * configure.in: Removed checks for libart.
885 * gdk-pixbuf/Makefile.am: Removed references to libart.
886 (noinst_HEADERS): Added gdk-pixbuf-private.h.
888 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
889 the version number of the libtool library to indicate that this
890 definitely is not compatible with the old usage. I know you love
893 * configure.in: Bumped version number to 0.7.0.
897 * gdk-pixbuf-config.in (--libs): We no longer require libart.
899 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
901 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
903 2000-04-06 Jonathan Blandford <jrb@redhat.com>
905 * gdk-pixbuf/testanimation.c (main): add more info to the
906 testanimation frames.
908 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
910 * gdk-pixbuf/gdk-pixbuf-animation.c
911 (gdk_pixbuf_animation_get_width): New accessor function.

916 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
918 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
919 is private information, and the art_pixbuf will go away soon.
921 2000-03-31 Mark Crichton <crichton@gimp.org>
923 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
924 and gdk_pixbuf_get_artpixbuf accessor functions.
926 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
928 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
929 gboolean instead of int.
931 2000-03-29 Radek Doulik <rodo@helixcode.com>
933 * gdk-pixbuf/gdk-pixbuf-animation.c
934 (gdk_pixbuf_animation_new_from_file): same as below
936 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
937 height in GdkPixbufAnimation
939 2000-03-28 Radek Doulik <rodo@helixcode.com>
941 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
942 context->frame_done_func and context->anim_done_func to make
943 progressive animation loading work
945 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
946 added priv->pixbuf = NULL as pixbuf is now in frame (and to make
947 gdk_pixbuf_loader_prepare happy)
948 (gdk_pixbuf_loader_frame_done): update animation bbox
950 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to

961 precendence of >> and & which was keeping composite_color
962 from working with non-gray images.
964 2000-03-08 Jonathan Blandford <jrb@redhat.com>
966 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.
967 (gdk_pixbuf__gif_image_load_animation): free the context.
969 2000-03-06 Arjan van de Ven <arjan@fenrus.demon.nl>
971 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
972 mis-interpretation of the Microsoft documentation. Now
973 it can load .BMP files that are not generated by The Gimp
976 2000-03-01 Mark Crichton <crichton@gimp.org>
978 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
979 fix the last auto* build bug (where we have libart, but no
982 * gdk-pixbuf/Makefile.am: Same.
984 2000-02-28 Matt Wilson <msw@redhat.com>
986 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
987 s/unsigned short/guint16/g, s/unsigned char/guint8/g
989 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
991 * README: We don't require libgif/ungif nor libXpm.
993 * NEWS: This was outdated, so updated it.
995 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
997 * gdk-pixbuf.m4: Use the correct name for
998 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing
1001 2000-02-21 Federico Mena Quintero <federico@helixcode.com>
1003 * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0.
1005 * doc/compiling.sgml: New appendix documenting the gdk-pixbuf
1006 library's particular options to configure.in.
1008 * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an
1011 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
1013 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
1014 Fixed typo in prototype name.
1016 * configure.in: Changed duplicated AC_MSG_CHECKING message to
1017 something more meaningful; now it is "checking whether dynamic
1020 * gdk-pixbuf/pixops/Makefile.am (noinst_PROGRAMS): Do not install
1021 the timescale program.
1023 Integrated Miguel de Icaza's <miguel@gnu.org> patch for optionally
1024 creating a single static library with all the image format modules

1083 prefix for the modules to load the information.
1085 * configure.in (GDK_PIXBUF_VERSION): New option --disable-modules
1086 lets the user specify that gdk-pixbuf should link all image loader
1087 code into the library instaed of creating shared library modules.
1089 (dynworks): Renamed the automake conditional DYNAMIC_MODULES_WORK
1090 to BUILD_DYNAMIC_MODULES.
1092 2000-02-19 Jonathan Blandford <jrb@redhat.com>
1094 * gdk-pixbuf/io-gif.c (new_context): fix case where initial
1095 colormap entry is Transparent.

1390 copy of an animated GIF if it appears multiple times in a web
1393 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
1394 animation functions here.
1395 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
1396 animation if the loader does not support multiframe loading and
1397 the single-frame load returned NULL. Check that the filename is
1398 not NULL. Updated inline documentation.
1399 (gdk_pixbuf_animation_ref): New function.
1400 (gdk_pixbuf_animation_unref): New function.
1401 Removed gdk_pixbuf_animation_destroy() in favor of reference

1409 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
1412 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
1413 with a reference count of 1.
1415 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
1416 gdk-pixbuf-animation.c.
1418 * doc/tmpl/animation.sgml: Populated. It is still missing a

1435 1999-12-23 Havoc Pennington <hp@pobox.com>
1437 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
1438 set to NULL here (specifically context->animation) was not being
1439 set to NULL. use g_new0() to alloc the struct.
1441 1999-12-20 Jonathan Blandford <jrb@redhat.com>
1443 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
1444 correctly. Progressive loading needs some work, but that all
1445 needs doing from the gdk-pixbuf-loader end, not here.
1447 1999-12-17 Jonathan Blandford <jrb@redhat.com>
1449 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
1450 moved the file here. It seems natural to put this function here,
1451 as that's where the gdk_pixbuf_new_from_file function is, but it's
1452 still a little convoluted. The source files might be played with
1455 1999-12-14 Jonathan Blandford <jrb@redhat.com>
1457 * gdk-pixbuf/gdk-pixbuf-loader.c
1458 (gdk_pixbuf_loader_get_animation): Gets the animation from the

1469 * gdk-pixbuf/gnome-canvas-pixbuf.c
1470 (gnome_canvas_pixbuf_class_init): Renamed arguments to
1471 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for

1501 Filled in body of function.
1502 (rgbconvert): Added GdkColormap parameter, and to all conversion
1504 (convert_real_slow): New function - should convert ANY visual/data
1505 format properly, but it aint fast. Used as a fallback when an
1506 optimised routine wont match.
1507 (rgbconvert): Do very specific tests on the data format to verify
1508 properly if the optimised version will do, otherwise use the
1509 fallback function for all other data formats.
1511 * gdk-pixbuf/Makefile.am: Re-enabled building of
1512 textpixbuf-drawable.
1514 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
1515 gdk_pixbuf_get_from_drawable().

1526 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
1527 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
1528 checks and API definition. The body needs filling in and it needs
1529 to do the Right Thing(tm) for pixmaps plus the given colormap and
1530 windows and their own colormaps.
1532 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
1533 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.

1570 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
1571 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
1572 want, send me a patch to do the conditional stuff properly.
1573 Otherwise, please read the GNOME Programming Guidelines,
1574 especially the "CVS policies" section.
1576 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
1578 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.

1661 * src/gdk-pixbuf-data.c: Fix includes.
1663 * src/gdk-pixbuf-loader.c: #include <config.h>
1665 * src/gdk-pixbuf-loader.h: Use angle brackets for the gdk-pixbuf

1669 since it is not finished.
1671 * src/gdk-pixbuf.h: Removed unused transformation prototypes.
1673 * src/gdk-pixbuf-util.c: New file with utility and convenience
1674 functions for pixbufs.
1676 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c.
1678 * doc/gdk-pixbuf-sections.txt: Added section for utility functions.
1680 * doc/Makefile.am (tmpl_sources): Added tmpl/util.sgml.
1682 * doc/gdk-pixbuf.sgml: Added the utilities section.
1684 * doc/tmpl/util.sgml: Documentation for the utility functions.
1686 1999-11-29 Owen Taylor <otaylor@redhat.com>
1688 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
1689 Keep the mask around until after we draw ... since
1690 the GC changes aren't flushed to the X server until we
1691 draw, destroying it before that may result in BadPixmap
1694 1999-11-30 Havoc Pennington <hp@pobox.com>
1696 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
1698 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
1700 1999-11-29 Federico Mena Quintero <federico@redhat.com>
1702 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
1703 should be made conditional, not blindly commented out.
1705 1999-11-29 Jonathan Blandford <jrb@redhat.com>
1707 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
1708 handle .ico files. Cool.
1710 1999-11-24 Jonathan Blandford <jrb@redhat.com>
1712 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
1715 1999-11-24 James Henstridge <james@daa.com.au>
1717 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
1718 top builddir rather than src. This still builds fine, and does not
1719 get gtk-doc into an infinite loop when trying to find all the source
1722 1999-11-23 Jonathan Blandford <jrb@redhat.com>
1724 * Removed #PRAGMA } from headers. Also, make compile if you don't
1725 have it installed, already.
1727 1999-11-22 Federico Mena Quintero <federico@redhat.com>
1729 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
1730 temporary buffer to the size of the interesction of the bounding
1731 box and the expose area, not the whole expose area. This speeds
1734 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
1735 not paint black on the mask, since we already cleared it in a
1736 single gdk_draw_rectangle() operation.
1738 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
1740 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
1742 1999-11-22 Havoc Pennington <hp@pobox.com>
1744 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
1745 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
1746 dependencies to LIBADD variables for loadable modules. Necessary
1747 for a Java dynamic loading thing to be able to figure it out.
1749 1999-11-22 Havoc Pennington <hp@pobox.com>
1751 * src/io-png.c (image_load_increment): Call the update_area
1752 callback depending on the number of rows loaded in this increment.
1754 * src/testpixbuf.c (main): slow down the progressive load demo
1756 1999-11-16 Havoc Pennington <hp@pobox.com>
1758 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
1760 1999-11-22 Jonathan Blandford <jrb@redhat.com>
1762 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
1763 for srcdir != buildir != . Beats me why; I can't figure it out.
1764 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
1766 1999-11-21 Jonathan Blandford <jrb@redhat.com>
1768 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
1769 <arjan@fenrus.demon.nl>
1771 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
1773 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
1774 Rework/reorder of the code. Each case has been separated into
1775 another function; its big but it should be quick.
1776 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
1777 opaque alpha information. Not all depths/formats have been
1778 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
1780 1999-11-17 Larry Ewing <lewing@gimp.org>
1782 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
1783 implement the bounds method correctly.
1784 (compute_viewport_affine): compute the affine need to fit the
1785 image within the viewport given by the args.
1786 (compute_render_affine): call compute_viewport_affine.
1788 1999-11-16 Havoc Pennington <hp@pobox.com>
1790 * src/gdk-pixbuf-drawable.h: Use includes from the current
1791 directory, not the system directory.
1793 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
1795 * src/testpixbuf-drawable.c: use includes from the current directory
1796 rather then from the system include directory as gdk-pixbuf
1797 includes are not yet installed when this is compiled.
1799 1999-11-13 Cody Russell <bratsche@dfw.net>
1800 * src/testpixbuf-drawable.c: Added a test program for drawable
1803 * src/Makefile.am: Build testpixbuf-drawable.
1805 1999-11-12 Cody Russell <bratsche@dfw.net>
1807 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.
1809 1999-11-10 Federico Mena Quintero <federico@redhat.com>

1813 * doc/gdk-pixbuf.signals: Put in the real names of signal
1816 * src/gdk-pixbuf-loader.c: Improved documentation comments.
1818 1999-11-10 Jonathan Blandford <jrb@redhat.com>
1820 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
1823 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
1824 correctly. Patch from Arjan to do so.
1826 1999-11-10 Michael Fulbright <drmike@redhat.com>
1828 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
1831 * src/testpixbuf.c: Added final queued draw when done loading image.
1833 1999-11-10 Jonathan Blandford <jrb@redhat.com>
1835 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
1838 1999-11-10 Federico Mena Quintero <federico@redhat.com>
1840 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
1843 1999-11-09 Federico Mena Quintero <federico@redhat.com>
1845 * src/io-png.c: Fixed some incompatible pointer initializations.
1847 * src/io-jpeg.c (image_load_increment): Remove unused variable.
1849 1999-11-09 Michael Fulbright <drmike@redhat.com>
1851 * src/testpixbuf.c: Fixed it to use timeout to read from file
1852 for progressive loading. Set TBF_KBPS=n, where n is the number of
1853 kilobytes/second to simulate in downloading. n has to be an integer.
1855 * src/io-jpeg.c: Slight cosmetic cleanup.
1857 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
1858 PBM loading has a similar problem and will address tomorrow.
1860 1999-11-09 Havoc Pennington <hp@pobox.com>
1862 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
1863 gdk-pixbuf-drawable stuff.
1865 1999-11-09 Federico Mena Quintero <federico@redhat.com>
1867 * configure.in: Bumped version number to 0.4.
1869 1999-11-09 Michael Fulbright <drmike@redhat.com>
1871 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
1872 all types of PNM files now.
1874 * src/io-jpeg.c (image_load_increment): Figured out problem with
1875 loading Progressive JPEG's progressively (say that 10 times fast).
1876 Currently for Progressive JPEG's the entire image is loaded before
1877 it is displayed. libjpeg supports a fancier mechanism which I may
1880 With these changes all JPEG formats appear to load properly for me.
1882 1999-11-08 Jonathan Blandford <jrb@redhat.com>
1884 * src/io-ras.c (image_load_increment): Final patch from Arjan.
1885 Seems to do progressive loading.
1887 1999-11-08 Michael Fulbright <drmike@redhat.com>
1889 * src/io-pnm.c image_load (): Fixed so we do not create a separate
1890 pixel buffer when reading in image - we reuse the pixel data in
1891 the GdkPixbuf structure instead.
1893 1999-11-08 Michael Fulbright <drmike@redhat.com>
1895 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
1896 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
1897 I can't seem to find a utility to convert into this format.
1898 Next is to add progressive loading support for the PNM format.
1900 1999-11-07 Federico Mena Quintero <federico@redhat.com>
1902 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
1903 of the width, height, x, and y setting and pixels arguments.
1905 1999-11-05 Jonathan Blandford <jrb@redhat.com>
1907 * src/io-ras.c (image_load): third patch. Now it seems to load.
1909 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
1910 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
1912 * src/io-ras.c (image_load): new file from Arjan van de Ven
1913 <arjan@fenrus.demon.nl> to begin the ras loader.
1915 1999-11-05 Federico Mena Quintero <federico@redhat.com>
1917 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
1918 for internal use only.
1920 * doc/gdk-pixbuf.sgml: Likewise.
1922 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
1924 1999-11-05 Michael Fulbright <drmike@redhat.com>
1926 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
1927 files from a file. Next step is support for ASCII files, and
1928 then incremental loading.
1930 1999-11-04 Federico Mena Quintero <federico@redhat.com>
1932 * Makefile.am: Added doc to SUBDIRS.
1934 1999-11-04 Michael Fulbright <drmike@redhat.com>
1936 * src/io-jpeg.c: Prettied up code slightly.
1937 * src/io-pnm.c: Start of pnm loader (from file and progressively).
1938 Doesn't do much yet (will finish tomorrow).
1939 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
1941 1999-11-04 Federico Mena Quintero <federico@redhat.com>
1943 * doc/tmpl/rendering.sgml: Populated.
1945 * doc/Makefile.am: Added the template files.
1947 1999-11-04 Havoc Pennington <hp@pobox.com>
1949 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
1950 docs, explain what a dither offset is for.
1951 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
1952 this function vs. gdk_pixbuf_render_to_drawable().
1954 1999-11-04 Havoc Pennington <hp@pobox.com>
1956 * configure.in: Use libart-config correctly; find gnome-config
1957 separately. Fix GNOME_LIBS to be correct in "no gnome installed
1960 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
1963 Patch untested in the inside-gnome-libs case, I need to commit
1964 then check out to the gnome-libs I'm using.
1966 1999-11-04 Michael Fulbright <drmike@redhat.com>
1968 * src/io-jpeg.c (image_begin_load): Add update_func callback.
1969 * src/io-jpeg.c (image_load_increment): Call updated callback when
1970 new graphic data decoded.
1972 1999-11-04 Jonathan Blandford <jrb@redhat.com>
1974 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_update): handle the
1976 * src/io-png.c (image_begin_load): add a update_func callback.
1977 * src/io-gif.c (image_begin_load): add a update_func callback.
1978 (gif_get_lzw): added the update_func ability
1980 * src/io-tiff.c (image_begin_load): add a update_func callback.
1982 1999-11-04 Federico Mena Quintero <federico@redhat.com>
1984 * doc/tmpl/gdk-pixbuf.sgml: Populated.
1986 * doc/tmpl/refcounting.sgml: Populated.
1988 * doc/tmpl/file-loading.sgml: Populated.
1990 * src/gdk-pixbuf.c: Added documentation comments.
1992 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Added
1993 documentation comments.
1995 * doc/: Finished integrating the documentation framework.
1997 1999-11-03 Federico Mena Quintero <federico@redhat.com>
1999 * configure.in: Removed libgif stuff now that we do not depend on it.
2000 Added the necessary cruft for gtk-doc.
2002 * src/Makefile.am: Unconditionally build the GIF loader.
2004 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2006 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
2007 Added a lot of comments to the file.
2009 * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
2012 1999-11-03 Michael Fulbright <drmike@redhat.com>
2014 * src/io-jpeg.c (image_load_increment): Further removal of
2015 bugginess in local buffering code. Handles grayscale jpegs
2018 * src/io-jpeg.c (image_load_stop): Was freeing local context
2019 for jpeg library before calling jpeg_decompres_finish ().
2021 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2023 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
2025 (gif_get_lzw): set the transparency to the right val.
2027 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2029 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
2030 Initiailize the x and y fields.
2031 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
2032 (PixbufPrivate): Renamed need_size_update to need_xform_update.
2033 (recompute_bounding_box): Do not use temporary values.
2035 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2037 * src/io-gif.c (set_gif_lzw_clear_code): new state. Fixes
2040 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): remove
2041 unneeded x,y,h,w vars.
2043 1999-11-03 Larry Ewing <lewing@gimp.org>
2045 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
2046 render_affine calculation for x,y offsets.
2047 (gnome_canvas_pixbuf_set_arg): add x,y args.
2048 (gnome_canvas_pixbuf_get_arg): add x,y args.
2049 (recompute_bounding_box): simply code using ArtDrect and the
2050 render_affine. Removed compute_xform_vectors as it was no longer
2053 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2055 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
2056 doofus. Return a distance, not a boolean, for opaque images.
2058 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
2059 rounding of bounding box coordinates.
2060 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
2061 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
2063 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2065 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
2067 1999-11-03 Michael Fulbright <drmike@redhat.com>
2069 * src/io-jpg.c (image_load_increment): Fixed code which moved
2070 buffer around as new data comes in to work properly. JPEG progressive
2071 loading should be working now except for grayscale JPEG's, which I
2072 will look into next.
2074 1999-11-03 <sopwith@redhat.com>
2075 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
2076 Also put dot printing back in.
2078 1999-11-03 <jrb@redhat.com>
2080 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
2083 1999-11-02 Cody Russell <bratsche@dfw.net>
2084 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
2085 if part of the requested image is offscreen, rather than clipping
2088 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2090 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
2091 for interlacing and progressive loading.
2093 1999-11-02 Cody Russell <bratsche@dfw.net>
2094 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
2095 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
2097 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2099 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
2100 It's a little slow though. )-:
2102 1999-11-02 Elliot Lee <sopwith@redhat.com>
2103 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
2104 write/load_increment operations const-correct.
2106 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2108 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
2109 Implemented the ::point() method. We do a simple containment test
2110 instead of a full distance calculation since the canvas is going
2111 to change to that scheme, anyways.
2113 1999-11-02 Elliot Lee <sopwith@redhat.com>
2115 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
2116 that are read from the input file.
2118 1999-11-02 Larry Ewing <lewing@gimp.org>
2120 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
2122 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
2125 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2127 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
2128 affine computation code from ::draw() to here, since it is needed
2129 by ::point() as well.
2131 1999-11-02 Elliot Lee <sopwith@redhat.com>
2133 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
2134 three functions, and eliminate duplication of code from write()
2135 and close(). Also fix bug where the 128-byte header was being
2138 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2139 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
2140 bounding box computation.
2142 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2144 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
2145 Drawing affines seem to work. Bounding box is fubared. ::point()
2146 is not implemented. This is a work in progress.
2148 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
2151 * configure.in: Sigh. We need to link in libgnomeui for the
2152 canvas stuff. This mess will disappear when gdk-pixbuf gets
2153 folded into gnome-libs.
2155 1999-10-30 Jonathan Blandford <jrb@redhat.com>
2157 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
2158 the right size, at a minimum, even if the image is squished and
2160 (ReadImage): lets get the offset right. This will let transparent
2163 1999-10-29 Michael Fulbright <drmike@redhat.com>
2165 * src/io-jpeg.c: image_load_increment(): Fixed bug when
2166 image width was not a multiple of 4 - always use the
2167 gdk_pixbuf rowstride to increment pointers!
2169 1999-10-29 Michael Fulbright <drmike@redhat.com>
2171 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
2172 Currently does not handle either progressive jpeg files (jpeg
2173 files with multiple scans at different quality settings), but
2174 I plan on adding this support soon. These are fairly rare in
2175 my experience, so it shouldn't slow people down too much.
2176 Grayscale jpegs also don't work but that should be easy to fix.
2178 1999-10-29 Michael Fulbright <drmike@redhat.com>
2180 * src/testpixbuf.c: Added title to windows so you can identify
2181 progressive and file windows.
2183 1999-10-29 Michael Fulbright <drmike@redhat.com>
2185 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
2186 load the image handler when we determine the image type.
2188 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
2189 previously static function load_image_handler () to
2190 a public function gdk_pixbuf_load_module (). It is needed in
2191 gdk-pixbuf-loader.c to load image handler modules. This function
2192 is different from gdk_pixbuf_get_module (), which only returns
2193 a reference to the required handler, because it actually loads
2194 the handler into memory. Both actions should possibly be combined
2195 in a convenience function since one w/o the other doesn't seem to

2255 (image_handler_load): Check in present working directory,
2256 makes it easier to debug for now

2400 GdkPixBuf to GdkPixbuf, for consistency with the function names
2401 (and it is also easier to type) :-)
2403 1999-10-18 Havoc Pennington <hp@pobox.com>
2405 * configure.in: Use AM_PATH_GLIB instead of glib-config directly

2417 comment out testpixbuf for now
2419 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2421 * configure.in: Use $GTK_LIBS as the extra libs when checking for
2422 libgif/libungif, as they need the X libraries. Fixes bug #2472.
2424 1999-10-10 Cody Russell <bratsche@dfw.net>
2425 * src/gdk-pixbuf-drawable.c: core function now determines whether
2426 the requested geometry is on screen or not, and if some is not
2427 then the request is clamped to geometry that is on the screen.
2429 Changed 'pixbuf' to 'art_pixbuf' in core function.
2431 1999-10-08 Michael Fulbright <drmike@redhat.com>
2433 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

2439 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
2440 them, but I wrote them).
2442 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
2445 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
2446 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

2527 * src/Makefile.am (*_LIB): Only build the relevant loaders which
2528 require extra libraries if we actually have those libraries.
2530 1999-07-23 Richard Hestilow <hestgray@ionet.net>
2532 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes

2540 calculation needs to be done.
2542 1999-07-18 Larry Ewing <lewing@gimp.org>
2547 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
2548 error cases but one or two in the common case. There are probably
2549 a few small ones left.
2551 1999-07-18 Mark Crichton <crichton@gimp.org>
2553 * configure.in: removed version.h.
2555 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability

2571 (config_func): bring this up to date with the new pixbuf_scale
2574 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
2575 loading code so that poeple can diagnose problems better.
2577 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
2578 no longer allocates a new pixbuf, which make things nicer for the
2579 rest of the code. Unfortunately there is still a problem with
2580 scaling rgba images.
2582 1999-07-16 Mark Crichton <crichton@gimp.org>
2584 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
2585 calls gdk_pixbuf_scale. However, something is not working.
2586 N.B.: current pixmap is now stored in user_data with a key of
