1 2000-08-02 Tor Lillqvist <tml@iki.fi>
7 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
9 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
10 one. Fix names of DLLs to have '-' instead of '_'.
12 2000-07-31 Elliot Lee <sopwith@redhat.com>
13 * io-wbmp.c: Some bug fixes - now tested to work.
15 2000-07-27 Elliot Lee <sopwith@redhat.com>
16 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add gdk_pixbuf_get_named_module() function to facilitate above change
17 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile: Implement loader for WBMP format.
18 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
20 2000-07-23 Tor Lillqvist <tml@iki.fi>
25 * pixops/makefile.mingw.in
26 * pixbuf_*.def: New files.
29 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
31 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
32 New function, to get the GTK+ installation directory from
33 the Windows Registry, where the installation program
34 for whatever software includes GTK+ has stored it.
36 Used to avoid having hardcoding the directory where to look for
37 loaders. This function is needed by gtk, too, so it should
38 really be just in one place. Maybe a small static library
39 one level up from here?
41 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
42 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
43 Open file in binary mode. This *is* standard C. (No-op on Unix,
46 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
48 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
50 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
52 * pixops/*.S: The Gas from mingw32 doesn't like the .type
53 pseudo-op. Conditionalise on __MINGW32__, but probably
54 should conditionalise on Gas version instead? Or could we
55 do without .type on all systems?
57 * pixops/timescale.c: Use g_get_current_time()
58 instead of gettimeofday().
60 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
62 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
64 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
66 * gdk-pixbuf.c: Add <string.h> include.
68 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
70 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
71 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
72 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
73 use g_object_new() instead of g_type_create_instance() which
74 is a private function for fundamental type implementations.
76 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
78 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
79 soname scheme for gdk-pixbuf.
81 2000-06-21 Havoc Pennington <hp@pobox.com>
83 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
84 (i.e. derivation is not allowed, and there are no virtual methods
86 (gdk_pixbuf_preinit): Call g_type_init() here.
87 (gdk_pixbuf_init): Add a user-friendly init function, for users
88 of standalone gdk-pixbuf
90 * gdk-pixbuf-animation.c: Convert to GObject, in the same
91 way GdkPixbufAnimation was done.
93 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
94 gdk_pixbuf_finalize() from API, since these are broken and don't
95 make sense with new GObject stuff.
97 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
99 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
100 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
103 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
105 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
106 so I needed something to warm my thighs. Running plain infinite
107 loops on your laptop to make it hot is not very much fun. A demo
108 of the gdk-pixbuf scaling functions is way better, and looks
111 * configure.in (AC_OUTPUT): Added the demo Makefile.
113 * Makefile.am (SUBDIRS): Added the demo directory.
115 2000-06-09 Larry Ewing <lewing@helixcode.com>
117 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
118 setjmp for the png error handler. It seems setting the error
119 handling functions does not avoid the jump, and so not calling
120 setjmp was causing the incremental loader to jump into lala land.
121 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
122 not sure this one is actually required but the docs say it must be
123 set for every call to a png_* function.
124 Also changed the comment to reflect the fact that setting the
125 error handlers does _not_ avoid the longjmp.
127 2000-06-06 Larry Ewing <lewing@helixcode.com>
129 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
130 take frame offest into account when trying to calculate the
131 animation bbox. Also set the width to the width not the height.
132 (gdk_pixbuf_loader_animation_done): cycle over the frames to
133 calculate bbox because now we finally have all the offset
134 information for each frame.
136 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
138 * configure.in: add some gtk parameters to the
139 GDK_PIXBUF_LIB²S and GDK_PIXBUG_INCLUDEDIR vars. One more
140 fight in my crusade for strange prefix compile...
142 2000-05-30 Not Zed <NotZed@HelixCode.com>
144 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
145 Initialise the error handler exit routine to our own. Note this
146 means that every function that accesses the jpeg lib on this
147 object MUST do a setjmp.
148 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
149 lib for handling fatal error.
150 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
151 your applications dont quit if there's a jpeg error!
153 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
155 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
156 from Frank de Lange <frank@unternet.org>.
158 2000-05-09 Darin Adler <darin@eazel.com>
160 * gdk-pixbuf/test-gdk-pixbuf.c:
161 Fixed includes to get rid of accidental GNOME dependency.
163 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
164 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
166 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
168 * configure.in: Bumped version number to 0.8.0.
170 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
171 file was not being distributed.
173 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
175 2000-05-09 Darin Adler <darin@eazel.com>
177 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
178 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
179 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
180 formats to 32-bit formats to re-use the high bits of the color values
181 so that white maps to full white.
183 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
185 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
186 detailed information about the structure and algorithms
187 of pixops so people can fix it instead of breaking it.
189 2000-05-04 Darin Adler <darin@eazel.com>
191 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
192 (composite_pixel), (composite_line):
193 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
194 Now that Owen explained the algorithm, I think I implemented it
195 right for the cases where the destination pixbuf is not opaque.
196 The test does seem to confirm it.
198 2000-05-04 Darin Adler <darin@eazel.com>
200 * gdk-pixbuf/.cvsignore:
201 * gdk-pixbuf/Makefile.am:
202 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
203 (load_pixel), (simple_composite_test_one),
204 (simple_composite_test_one_type), (simple_composite_test), (main):
205 Added some tests of composite to highlight problems in the old
206 implementation. These tests run without any user interaction.
207 Just do "make check".
209 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
210 (composite_pixel), (composite_line): Fix composite to do a textbook
211 "A over B" composite. This was clearly the intent, and it was easy
212 to fix the code to do it. (Note to those that read my earlier tries
213 at a patch; this version fixes typos that were present in all
214 my patch attempts. I checked the final version by adding more tests.)
216 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
218 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
219 offset y coordinate accordining to render_y0.
221 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
224 2000-04-22 James Henstridge <james@daa.com.au>
226 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
227 package to the devel package. The only file installed in bin is
228 gdk-pixbuf-config, which belongs in -devel. This should allow having
229 multiple versions of the main gdk-pixbuf package installed.
231 2000-04-17 Karl Eichwalder <ke@suse.de>
233 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
234 Reported by Jens Finke.
236 2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
238 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
239 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
241 2000-04-13 James Henstridge <james@daa.com.au>
243 * configure.in: when performing the configure check to see if
244 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
245 rather than the other way round. Also, call AC_MSG_RESULT in the
246 even that dynamic modules were not supported.
248 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
250 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
251 hook to the last unref operation.
253 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
254 function to set the last unref handler for a pixbuf.
255 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
256 It calls the pixbuf's destroy notification function and frees the
257 GdkPixbuf structure itself.
258 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
261 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
262 for the last unref handler and its user data.
264 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
265 g_new0() to allocate the pixbuf.
267 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
268 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
269 was not specifying the `frame' argument.
271 * gdk-pixbuf/gdk-pixbuf-animation.c
272 (gdk_pixbuf_animation_get_width): Fixed docstring.
273 (gdk_pixbuf_animation_get_height): Likewise.
274 (gdk_pixbuf_animation_get_num_frames): Likewise.
275 (gdk_pixbuf_animation_get_frames): Likewise.
277 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
280 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
282 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
284 * doc/tmpl/refcounting.sgml: Updated with the information about
285 the last unref handler.
287 * doc/tmpl/*.sgml: Markup tweaks.
289 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
290 update the libtool version number for libgnomecanvaspixbuf as
292 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
293 as well, or the old ones won't work with the new stuff. Also,
294 renamed the modules as follows.
296 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
297 modules are called "libpixbufloader-<format>.so" instead of
298 "libpixbuf-<format>.so". They needed renaming so that the new
299 loaders won't overwrite the old ones; even with the versioning
300 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
303 2000-04-12 Paolo Molaro <lupus@debian.org>
305 * .cvsignore, src/.cvsignore: shut up cvs.
307 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
309 Most of this patch is based on a patch by Havoc Pennington
310 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
311 remove the libart dependency.
313 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
314 (GdkColorspace): New enum that for now only contains
316 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
317 notification function.
318 (GdkInterpType): New num with interpolation types.
320 * *.[ch]: Replace the libart stuff with our own stuff.
322 * pixops/*.[ch]: Likewise.
324 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
325 declarations of the GdkPixbuf structures.
327 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
329 (gdk_pixbuf_get_format): Constify.
330 (gdk_pixbuf_get_n_channels): Constify.
331 (gdk_pixbuf_get_has_alpha): Constify.
332 (gdk_pixbuf_get_bits_per_sample): Constify.

335 (gdk_pixbuf_get_height): Constify.
336 (gdk_pixbuf_get_rowstride): Constify.
338 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
341 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
342 bits_per_sample argument; currently only 8 bits per sample are
345 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
347 (gdk_pixbuf_frame_get_x_offset): New accessor.
348 (gdk_pixbuf_frame_get_y_offset): New accessor.
349 (gdk_pixbuf_frame_get_delay_time): New accessor.
350 (gdk_pixbuf_frame_get_action): New accessor.
352 * gdk-pixbuf/gdk-pixbuf-render.c
353 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
354 mask rectangle for pixbufs without an alpha channel, set the
355 *mask_return to NULL.
357 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
359 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
361 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
362 preconditions. Maybe we should also check for the colorspace,
363 bits per pixel, and such.
364 (gdk_pixbuf_composite): Likewise.
365 (gdk_pixbuf_composite_color): Likewise.
366 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
367 cannot allocate the new pixbuf.
368 (gdk_pixbuf_composite_color_simple): Likewise.
370 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
371 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
374 * gdk-pixbuf/io-bmp.c: Fix includes.
376 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
381 * configure.in: Removed checks for libart.
383 * gdk-pixbuf/Makefile.am: Removed references to libart.
384 (noinst_HEADERS): Added gdk-pixbuf-private.h.
386 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
387 the version number of the libtool library to indicate that this
388 definitely is not compatible with the old usage. I know you love
391 * configure.in: Bumped version number to 0.7.0.
395 * gdk-pixbuf-config.in (--libs): We no longer require libart.
397 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
399 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
401 2000-04-06 Jonathan Blandford <jrb@redhat.com>
403 * gdk-pixbuf/testanimation.c (main): add more info to the
404 testanimation frames.
406 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
408 * gdk-pixbuf/gdk-pixbuf-animation.c
409 (gdk_pixbuf_animation_get_width): New accessor function.
410 (gdk_pixbuf_animation_get_height): New accessor function.
411 (gdk_pixbuf_animation_get_num_frames): New accessor function.
412 (gdk_pixbuf_animation_get_frames): New accessor function.
414 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
416 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
417 is private information, and the art_pixbuf will go away soon.
419 2000-03-31 Mark Crichton <crichton@gimp.org>
421 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
422 and gdk_pixbuf_get_artpixbuf accessor functions.
424 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
426 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
427 gboolean instead of int.
429 2000-03-29 Radek Doulik <rodo@helixcode.com>
431 * gdk-pixbuf/gdk-pixbuf-animation.c
432 (gdk_pixbuf_animation_new_from_file): same as below
434 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
435 height in GdkPixbufAnimation
437 2000-03-28 Radek Doulik <rodo@helixcode.com>
439 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
440 context->frame_done_func and context->anim_done_func to make
441 progressive animation loading work
443 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
444 added priv->pixbuf = NULL as pixbuf is now in frame (and to make
445 gdk_pixbuf_loader_prepare happy)
446 (gdk_pixbuf_loader_frame_done): update animation bbox
448 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
451 2000-03-27 Radek Doulik <rodo@helixcode.com>
453 * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
454 instead of width and height
456 2000-03-27 Owen Taylor <otaylor@redhat.com>
458 * gdk-pixbuf/pixops/pixops.c: Fix problem with
459 precendence of >> and & which was keeping composite_color
460 from working with non-gray images.
462 2000-03-08 Jonathan Blandford <jrb@redhat.com>
464 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.
465 (gdk_pixbuf__gif_image_load_animation): free the context.
467 2000-03-06 Arjan van de Ven <arjan@fenrus.demon.nl>
469 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
470 mis-interpretation of the Microsoft documentation. Now
471 it can load .BMP files that are not generated by The Gimp
474 2000-03-01 Mark Crichton <crichton@gimp.org>
476 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
477 fix the last auto* build bug (where we have libart, but no
480 * gdk-pixbuf/Makefile.am: Same.
482 2000-02-28 Matt Wilson <msw@redhat.com>
484 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
485 s/unsigned short/guint16/g, s/unsigned char/guint8/g
487 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
489 * README: We don't require libgif/ungif nor libXpm.
491 * NEWS: This was outdated, so updated it.
493 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
495 * gdk-pixbuf.m4: Use the correct name for
496 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing
499 2000-02-21 Federico Mena Quintero <federico@helixcode.com>
501 * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0.
503 * doc/compiling.sgml: New appendix documenting the gdk-pixbuf
504 library's particular options to configure.in.
506 * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an
509 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
511 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
512 Fixed typo in prototype name.
514 * configure.in: Changed duplicated AC_MSG_CHECKING message to
515 something more meaningful; now it is "checking whether dynamic
518 * gdk-pixbuf/pixops/Makefile.am (noinst_PROGRAMS): Do not install
519 the timescale program.
521 Integrated Miguel de Icaza's <miguel@gnu.org> patch for optionally
522 creating a single static library with all the image format modules
525 2000-02-20 Miguel de Icaza <miguel@gnu.org>
527 * gdk-pixbuf/io-xpm.c (gdk_pixbuf__xpm_image_load): Add prefix.
528 (gdk_pixbuf__xpm_image_load_xpm_data): Add prefix.
530 * gdk-pixbuf/io-tiff.c (gdk_pixbuf__tiff_image_load_real): Add prefix.
531 (gdk_pixbuf__tiff_image_stop_load): Add prefix.
532 (gdk_pixbuf__tiff_image_load_increment): Add prefix.
533 (gdk_pixbuf__tiff_image_load): Add prefix.
534 (gdk_pixbuf__tiff_image_stop_load): Update invocation.
535 (gdk_pixbuf__tiff_image_begin_load): Add prefix.
537 * gdk-pixbuf/io-ras.c (gdk_pixbuf__ras_image_load): Add prefix.
538 (gdk_pixbuf__ras_image_load): Updated invocation.

891 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
892 animation functions here.
893 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
894 animation if the loader does not support multiframe loading and
895 the single-frame load returned NULL. Check that the filename is
896 not NULL. Updated inline documentation.

898 (gdk_pixbuf_animation_unref): New function.
899 Removed gdk_pixbuf_animation_destroy() in favor of reference

907 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
910 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
911 with a reference count of 1.
913 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
914 gdk-pixbuf-animation.c.
916 * doc/tmpl/animation.sgml: Populated. It is still missing a

933 1999-12-23 Havoc Pennington <hp@pobox.com>
935 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
936 set to NULL here (specifically context->animation) was not being
937 set to NULL. use g_new0() to alloc the struct.
939 1999-12-20 Jonathan Blandford <jrb@redhat.com>
941 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
942 correctly. Progressive loading needs some work, but that all
943 needs doing from the gdk-pixbuf-loader end, not here.
945 1999-12-17 Jonathan Blandford <jrb@redhat.com>
947 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
948 moved the file here. It seems natural to put this function here,
949 as that's where the gdk_pixbuf_new_from_file function is, but it's
950 still a little convoluted. The source files might be played with
953 1999-12-14 Jonathan Blandford <jrb@redhat.com>
955 * gdk-pixbuf/gdk-pixbuf-loader.c
956 (gdk_pixbuf_loader_get_animation): Gets the animation from the

967 * gdk-pixbuf/gnome-canvas-pixbuf.c
968 (gnome_canvas_pixbuf_class_init): Renamed arguments to
969 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for

1000 (rgbconvert): Added GdkColormap parameter, and to all conversion
1002 (convert_real_slow): New function - should convert ANY visual/data
1003 format properly, but it aint fast. Used as a fallback when an
1004 optimised routine wont match.
1005 (rgbconvert): Do very specific tests on the data format to verify
1006 properly if the optimised version will do, otherwise use the
1007 fallback function for all other data formats.
1009 * gdk-pixbuf/Makefile.am: Re-enabled building of
1010 textpixbuf-drawable.
1012 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
1013 gdk_pixbuf_get_from_drawable().
1015 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
1017 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
1018 bug on two occasions.
1019 * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu

1024 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
1025 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
1026 checks and API definition. The body needs filling in and it needs
1027 to do the Right Thing(tm) for pixmaps plus the given colormap and
1028 windows and their own colormaps.
1030 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
1031 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
1033 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
1035 * doc/tmpl/from-drawables.sgml: Populated.

1068 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
1069 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
1070 want, send me a patch to do the conditional stuff properly.

1095 except for the signature and 2 extra fields for the hotspot.
1097 1999-12-03 Federico Mena Quintero <federico@redhat.com>
1099 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):

1105 explain this function better.
1107 1999-12-02 Federico Mena Quintero <federico@redhat.com>
1109 Source files moved from src/ to gdk-pixbuf/, to be consistent with

1182 * doc/tmpl/util.sgml: Documentation for the utility functions.
1184 1999-11-29 Owen Taylor <otaylor@redhat.com>
1186 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
1187 Keep the mask around until after we draw ... since
1188 the GC changes aren't flushed to the X server until we
1189 draw, destroying it before that may result in BadPixmap
1192 1999-11-30 Havoc Pennington <hp@pobox.com>
1194 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
1196 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
1198 1999-11-29 Federico Mena Quintero <federico@redhat.com>
1200 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
1201 should be made conditional, not blindly commented out.
1203 1999-11-29 Jonathan Blandford <jrb@redhat.com>
1205 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
1206 handle .ico files. Cool.
1208 1999-11-24 Jonathan Blandford <jrb@redhat.com>
1210 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
1213 1999-11-24 James Henstridge <james@daa.com.au>
1215 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
1216 top builddir rather than src. This still builds fine, and does not
1217 get gtk-doc into an infinite loop when trying to find all the source
1220 1999-11-23 Jonathan Blandford <jrb@redhat.com>
1222 * Removed #PRAGMA } from headers. Also, make compile if you don't
1223 have it installed, already.
1225 1999-11-22 Federico Mena Quintero <federico@redhat.com>
1227 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
1228 temporary buffer to the size of the interesction of the bounding
1229 box and the expose area, not the whole expose area. This speeds
1232 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
1233 not paint black on the mask, since we already cleared it in a
1234 single gdk_draw_rectangle() operation.
1236 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
1238 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
1240 1999-11-22 Havoc Pennington <hp@pobox.com>
1242 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
1243 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
1244 dependencies to LIBADD variables for loadable modules. Necessary
1245 for a Java dynamic loading thing to be able to figure it out.
1247 1999-11-22 Havoc Pennington <hp@pobox.com>
1249 * src/io-png.c (image_load_increment): Call the update_area
1250 callback depending on the number of rows loaded in this increment.
1252 * src/testpixbuf.c (main): slow down the progressive load demo
1254 1999-11-16 Havoc Pennington <hp@pobox.com>
1256 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
1258 1999-11-22 Jonathan Blandford <jrb@redhat.com>
1260 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
1261 for srcdir != buildir != . Beats me why; I can't figure it out.
1262 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
1264 1999-11-21 Jonathan Blandford <jrb@redhat.com>
1266 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
1267 <arjan@fenrus.demon.nl>
1269 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
1271 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
1272 Rework/reorder of the code. Each case has been separated into
1273 another function; its big but it should be quick.
1274 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
1275 opaque alpha information. Not all depths/formats have been
1276 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
1278 1999-11-17 Larry Ewing <lewing@gimp.org>
1280 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
1281 implement the bounds method correctly.
1282 (compute_viewport_affine): compute the affine need to fit the
1283 image within the viewport given by the args.
1284 (compute_render_affine): call compute_viewport_affine.
1286 1999-11-16 Havoc Pennington <hp@pobox.com>
1288 * src/gdk-pixbuf-drawable.h: Use includes from the current
1289 directory, not the system directory.
1291 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
1293 * src/testpixbuf-drawable.c: use includes from the current directory
1294 rather then from the system include directory as gdk-pixbuf
1295 includes are not yet installed when this is compiled.
1297 1999-11-13 Cody Russell <bratsche@dfw.net>
1298 * src/testpixbuf-drawable.c: Added a test program for drawable
1301 * src/Makefile.am: Build testpixbuf-drawable.
1303 1999-11-12 Cody Russell <bratsche@dfw.net>
1305 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.

1316 1999-11-10 Jonathan Blandford <jrb@redhat.com>
1318 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
1321 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
1322 correctly. Patch from Arjan to do so.
1324 1999-11-10 Michael Fulbright <drmike@redhat.com>
1326 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
1329 * src/testpixbuf.c: Added final queued draw when done loading image.
1331 1999-11-10 Jonathan Blandford <jrb@redhat.com>
1333 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
1336 1999-11-10 Federico Mena Quintero <federico@redhat.com>
1338 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
1341 1999-11-09 Federico Mena Quintero <federico@redhat.com>
1343 * src/io-png.c: Fixed some incompatible pointer initializations.
1345 * src/io-jpeg.c (image_load_increment): Remove unused variable.
1347 1999-11-09 Michael Fulbright <drmike@redhat.com>
1349 * src/testpixbuf.c: Fixed it to use timeout to read from file
1350 for progressive loading. Set TBF_KBPS=n, where n is the number of
1351 kilobytes/second to simulate in downloading. n has to be an integer.
1353 * src/io-jpeg.c: Slight cosmetic cleanup.
1355 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
1356 PBM loading has a similar problem and will address tomorrow.
1358 1999-11-09 Havoc Pennington <hp@pobox.com>
1360 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
1361 gdk-pixbuf-drawable stuff.
1363 1999-11-09 Federico Mena Quintero <federico@redhat.com>
1365 * configure.in: Bumped version number to 0.4.
1367 1999-11-09 Michael Fulbright <drmike@redhat.com>
1369 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
1370 all types of PNM files now.
1372 * src/io-jpeg.c (image_load_increment): Figured out problem with
1373 loading Progressive JPEG's progressively (say that 10 times fast).
1374 Currently for Progressive JPEG's the entire image is loaded before
1375 it is displayed. libjpeg supports a fancier mechanism which I may
1378 With these changes all JPEG formats appear to load properly for me.
1380 1999-11-08 Jonathan Blandford <jrb@redhat.com>
1382 * src/io-ras.c (image_load_increment): Final patch from Arjan.
1383 Seems to do progressive loading.
1385 1999-11-08 Michael Fulbright <drmike@redhat.com>
1387 * src/io-pnm.c image_load (): Fixed so we do not create a separate
1388 pixel buffer when reading in image - we reuse the pixel data in
1389 the GdkPixbuf structure instead.
1391 1999-11-08 Michael Fulbright <drmike@redhat.com>
1393 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
1394 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
1395 I can't seem to find a utility to convert into this format.
1396 Next is to add progressive loading support for the PNM format.
1398 1999-11-07 Federico Mena Quintero <federico@redhat.com>
1400 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
1401 of the width, height, x, and y setting and pixels arguments.
1403 1999-11-05 Jonathan Blandford <jrb@redhat.com>

1408 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
1410 * src/io-ras.c (image_load): new file from Arjan van de Ven
1411 <arjan@fenrus.demon.nl> to begin the ras loader.
1413 1999-11-05 Federico Mena Quintero <federico@redhat.com>
1415 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
1416 for internal use only.
1418 * doc/gdk-pixbuf.sgml: Likewise.
1420 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
1422 1999-11-05 Michael Fulbright <drmike@redhat.com>

1426 then incremental loading.
1428 1999-11-04 Federico Mena Quintero <federico@redhat.com>
1430 * Makefile.am: Added doc to SUBDIRS.
1432 1999-11-04 Michael Fulbright <drmike@redhat.com>
1434 * src/io-jpeg.c: Prettied up code slightly.
1435 * src/io-pnm.c: Start of pnm loader (from file and progressively).
1436 Doesn't do much yet (will finish tomorrow).
1437 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
1439 1999-11-04 Federico Mena Quintero <federico@redhat.com>
1441 * doc/tmpl/rendering.sgml: Populated.
1443 * doc/Makefile.am: Added the template files.
1445 1999-11-04 Havoc Pennington <hp@pobox.com>
1447 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
1448 docs, explain what a dither offset is for.
1449 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
1450 this function vs. gdk_pixbuf_render_to_drawable().
1452 1999-11-04 Havoc Pennington <hp@pobox.com>
1454 * configure.in: Use libart-config correctly; find gnome-config
1455 separately. Fix GNOME_LIBS to be correct in "no gnome installed
1458 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
1461 Patch untested in the inside-gnome-libs case, I need to commit
1462 then check out to the gnome-libs I'm using.
1464 1999-11-04 Michael Fulbright <drmike@redhat.com>
1466 * src/io-jpeg.c (image_begin_load): Add update_func callback.
1467 * src/io-jpeg.c (image_load_increment): Call updated callback when
1468 new graphic data decoded.
1470 1999-11-04 Jonathan Blandford <jrb@redhat.com>

1512 * src/io-jpeg.c (image_load_increment): Further removal of
1513 bugginess in local buffering code. Handles grayscale jpegs
1516 * src/io-jpeg.c (image_load_stop): Was freeing local context
1517 for jpeg library before calling jpeg_decompres_finish ().
1519 1999-11-03 Jonathan Blandford <jrb@redhat.com>
1521 * src/io-gif.c (image_load_increment): now handle arbitrary buffer

1544 render_affine calculation for x,y offsets.
1545 (gnome_canvas_pixbuf_set_arg): add x,y args.
1546 (gnome_canvas_pixbuf_get_arg): add x,y args.
1547 (recompute_bounding_box): simply code using ArtDrect and the
1548 render_affine. Removed compute_xform_vectors as it was no longer
1551 1999-11-03 Federico Mena Quintero <federico@redhat.com>
1553 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
1554 doofus. Return a distance, not a boolean, for opaque images.
1556 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
1557 rounding of bounding box coordinates.
1558 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
1559 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
1561 1999-11-03 Jonathan Blandford <jrb@redhat.com>
1563 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
1565 1999-11-03 Michael Fulbright <drmike@redhat.com>
1567 * src/io-jpg.c (image_load_increment): Fixed code which moved
1568 buffer around as new data comes in to work properly. JPEG progressive
1569 loading should be working now except for grayscale JPEG's, which I
1570 will look into next.
1572 1999-11-03 <sopwith@redhat.com>
1573 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
1574 Also put dot printing back in.
1576 1999-11-03 <jrb@redhat.com>
1578 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
1581 1999-11-02 Cody Russell <bratsche@dfw.net>
1582 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
1583 if part of the requested image is offscreen, rather than clipping
1586 1999-11-02 Jonathan Blandford <jrb@redhat.com>
1588 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
1589 for interlacing and progressive loading.
1591 1999-11-02 Cody Russell <bratsche@dfw.net>
1592 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
1593 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
1595 1999-11-02 Jonathan Blandford <jrb@redhat.com>
1597 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
1598 It's a little slow though. )-:

1606 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
1607 Implemented the ::point() method. We do a simple containment test
1608 instead of a full distance calculation since the canvas is going
1609 to change to that scheme, anyways.
1611 1999-11-02 Elliot Lee <sopwith@redhat.com>
1613 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
1614 that are read from the input file.
1616 1999-11-02 Larry Ewing <lewing@gimp.org>
1618 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
1620 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
1623 1999-11-02 Federico Mena Quintero <federico@redhat.com>
1625 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
1626 affine computation code from ::draw() to here, since it is needed
1627 by ::point() as well.
1629 1999-11-02 Elliot Lee <sopwith@redhat.com>
1631 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
1632 three functions, and eliminate duplication of code from write()
1633 and close(). Also fix bug where the 128-byte header was being
1636 1999-11-01 Federico Mena Quintero <federico@redhat.com>
1637 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
1638 bounding box computation.
1640 1999-11-01 Federico Mena Quintero <federico@redhat.com>
1642 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
1643 Drawing affines seem to work. Bounding box is fubared. ::point()
1644 is not implemented. This is a work in progress.
1646 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
1649 * configure.in: Sigh. We need to link in libgnomeui for the
1650 canvas stuff. This mess will disappear when gdk-pixbuf gets
1651 folded into gnome-libs.
1653 1999-10-30 Jonathan Blandford <jrb@redhat.com>
1655 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
1656 the right size, at a minimum, even if the image is squished and
1658 (ReadImage): lets get the offset right. This will let transparent
1661 1999-10-29 Michael Fulbright <drmike@redhat.com>
1663 * src/io-jpeg.c: image_load_increment(): Fixed bug when
1664 image width was not a multiple of 4 - always use the
1665 gdk_pixbuf rowstride to increment pointers!
1667 1999-10-29 Michael Fulbright <drmike@redhat.com>
1669 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
1670 Currently does not handle either progressive jpeg files (jpeg
1671 files with multiple scans at different quality settings), but
1672 I plan on adding this support soon. These are fairly rare in
1673 my experience, so it shouldn't slow people down too much.
1674 Grayscale jpegs also don't work but that should be easy to fix.
1676 1999-10-29 Michael Fulbright <drmike@redhat.com>
1678 * src/testpixbuf.c: Added title to windows so you can identify
1679 progressive and file windows.
1681 1999-10-29 Michael Fulbright <drmike@redhat.com>
1683 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
1684 load the image handler when we determine the image type.
1686 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
1687 previously static function load_image_handler () to
1688 a public function gdk_pixbuf_load_module (). It is needed in
1689 gdk-pixbuf-loader.c to load image handler modules. This function
1690 is different from gdk_pixbuf_get_module (), which only returns
1691 a reference to the required handler, because it actually loads
1692 the handler into memory. Both actions should possibly be combined
1693 in a convenience function since one w/o the other doesn't seem to
1696 1999-10-28 Jonathan Blandford <jrb@redhat.com>
1698 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a

1703 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
1704 function to render a portion of a pixbuf to a drawable. Ignores
1705 alpha information and takes in a GC.
1706 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
1707 portion of a pixbuf to a drawable. It automatically creates a GC
1708 and a clipping mask for alpha pixbufs.
1710 1999-10-28 Jonathan Blandford <jrb@redhat.com>
1712 * src/gdk-pixbuf.h: turned convenience macros into convenience
1713 functions so some error checking could be added.
1715 * src/io-tiff.c (image_load_increment): started work on the tiff
1716 non-incremental loader.
1717 (image_begin_load): Finished the incremental loader.

1724 1999-10-27 Federico Mena Quintero <federico@redhat.com>
1726 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
1727 function to threshold a pixbuf's alpha channel into a bitmap.
1729 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
1730 contemplate future extensions to ArtPixBuf's formats.
1732 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
1734 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
1735 macros to fetch the ArtPixBuf's fields.
1737 1999-10-27 Havoc Pennington <hp@pobox.com>

1742 code into separate function
1743 (png_info_callback): Use setup_png_transformations
1745 1999-10-27 Havoc Pennington <hp@pobox.com>
1747 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
1748 properly whether the XPM module has already been loaded
1749 (gdk_pixbuf_new_from_file): Check properly if loader module
1750 was already loaded (was checking if load symbol was present
1751 in order to decide whether to re-load; should check module !=
1752 NULL, then load != NULL)
1753 (image_handler_load): Check in present working directory,
1754 makes it easier to debug for now
1755 (file_formats): This array initializer was seriously on crack,
1756 was assigning a function pointer to a GModule*
1758 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
1760 1999-10-27 Havoc Pennington <hp@pobox.com>
1762 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_finalize):

1764 (gdk_pixbuf_loader_destroy): ditto
1766 1999-10-27 Federico Mena Quintero <federico@redhat.com>
1768 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
1769 GdkPixbufLoader, not a GtkObject.
1770 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
1771 (gdk_pixbuf_loader_get_type): Documented.
1772 (gdk_pixbuf_loader_class_init): Initialize the parent class
1774 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
1775 class destroy function.
1776 (gdk_pixbuf_loader_new): Documented.
1777 (gdk_pixbuf_loader_finalize): Call the parent class finalize
1779 (gdk_pixbuf_loader_write): Use size_t for count.
1781 1999-10-27 Michael Fulbright <drmike@redhat.com>
1783 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
1784 logic so we only try to close loader if it wasn't previously closed.
1786 1999-10-27 Michael Fulbright <drmike@redhat.com>
1788 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of

1815 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
1817 1999-10-22 Havoc Pennington <hp@pobox.com>
1819 * src/io-xpm.c (mem_buffer): Clean up stupid
1820 increment-inside-array-dereference thing
1822 * src/testpixbuf.c: Add XPM data tests.
1824 * src/io-xpm.c: Make the XPM data buffer const, fix const
1825 correctness throughout the code.
1827 1999-10-22 Havoc Pennington <hp@pobox.com>

1837 function, loads pixbuf from xpm data
1838 (image_handler_load): Add g_return_if_fail() to ensure the same
1839 module isn't loaded twice. Add g_module_symbol() to scan for XPM
1842 1999-10-22 Federico Mena Quintero <federico@redhat.com>
1844 * src/io-png.c (image_load): Patch from Kristian Hogsberg
1845 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
1846 buffers; the rows can be read in directly into the main pixel
1849 1999-10-20 Federico Mena Quintero <federico@redhat.com>
1851 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
1853 1999-10-20 Federico Mena Quintero <federico@redhat.com>
1855 * configure.in: Bumped version number to 0.3.
1857 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
1858 version number for the library.
1860 1999-10-20 Federico Mena Quintero <federico@redhat.com>
1862 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
1863 all memory management of the buffer is done by libart.
1865 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
1866 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
1868 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
1869 terms of the libart functions. Removed the old code.
1871 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
1872 symbols. Saving will not be implemented in GdkPixbuf.
1874 * src/io-gif.c: Removed the saving stub.
1875 (image_load): Fixed memory management to fail gracefully if we run
1876 out of memory while loading the image. Close the gif file when we
1877 are done. This still needs more error handling for the DGif
1880 * src/io-jpeg.c (image_load): Some robustness fixes.
1882 * src/io-png.c: Removed the saving stuff.
1883 (image_load): Some memory management fixes.

1895 1999-10-18 Federico Mena Quintero <federico@redhat.com>
1897 * src/*: Reindented to use the GNOME Indentation. Renamed
1898 GdkPixBuf to GdkPixbuf, for consistency with the function names
1899 (and it is also easier to type) :-)
1901 1999-10-18 Havoc Pennington <hp@pobox.com>
1903 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
1905 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
1907 1999-10-18 Havoc Pennington <hp@pobox.com>
1909 * Makefile.am (SUBDIRS): Remove "macros"
1911 * configure.in: Don't use GNOME_INIT, handle case where we are
1912 inside gnome-libs. AM_PATH_GTK for the GIF test
1914 * src/Makefile.am: Change flags to work without libgnomeui,
1915 comment out testpixbuf for now
1917 1999-10-18 Federico Mena Quintero <federico@redhat.com>
1919 * configure.in: Use $GTK_LIBS as the extra libs when checking for
1920 libgif/libungif, as they need the X libraries. Fixes bug #2472.
1922 1999-10-10 Cody Russell <bratsche@dfw.net>
1923 * src/gdk-pixbuf-drawable.c: core function now determines whether
1924 the requested geometry is on screen or not, and if some is not
1925 then the request is clamped to geometry that is on the screen.
1927 Changed 'pixbuf' to 'art_pixbuf' in core function.
1929 1999-10-08 Michael Fulbright <drmike@redhat.com>
1931 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

1934 if no filename given to test program.
1936 1999-10-07 Cody Russell <bratsche@dfw.net>
1937 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
1938 them, but I wrote them).
1940 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
1943 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
1944 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

1964 * src/io-tiff.c (image_load): ditto + fix leak
1966 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
1967 crashes this module ( add warning :-)
1969 * src/io-bmp.c (image_load): ditto.
1971 * src/io-gif.c (image_load): ditto.
1973 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
1975 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
1976 it doesn't crash scaling with alpha.
1978 1999-09-17 Federico Mena Quintero <federico@redhat.com>
1980 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
1982 * src/io-gif.c (image_load): Likewise.
1984 * src/io-jpeg.c (image_load): Likewise.
1986 * src/io-png.c (image_load): Likewise.

2001 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
2002 to unallocated memory (row_ptr), and fixed its type as well. Take
2003 into account the ArtPixbuf's rowstride when assigning the row
2006 * src/gdk-pixbuf.c: Fixup includes.
2008 * src/gdk-pixbuf-io.c: Likewise.
2010 Sat Jul 31 19:19:47 CEST 1999

2017 * src/io-png.c (image_save): Added PNG saving function
2019 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
2020 image_save(GdkPixBuf *p, FILE *f, ...)
2023 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
2025 * src/Makefile.am (*_LIB): Only build the relevant loaders which
2026 require extra libraries if we actually have those libraries.
2028 1999-07-23 Richard Hestilow <hestgray@ionet.net>
2030 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
2031 * gdk_pixbufConf.sh.in: Added for gnome-config
2033 * configure.in: Modified to generate gdk_pixbufConf.sh
2035 1999-07-20 Mark Crichton <crichton@gimp.org>
2037 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
2038 calculation needs to be done.
2040 1999-07-18 Larry Ewing <lewing@gimp.org>
2045 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
2046 error cases but one or two in the common case. There are probably
2047 a few small ones left.
2049 1999-07-18 Mark Crichton <crichton@gimp.org>
2051 * configure.in: removed version.h.
2053 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
2056 1999-07-17 Mark Crichton <crichton@gimp.org>
2058 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
2059 (gdk_pixbuf_rotate): Added pixbuf rotation code.

2062 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
2065 1999-07-16 Larry Ewing <lewing@gimp.org>
2067 * src/testpixbuf.c (expose_func): reverted the expose everything
2068 changes, I'm not sure why these went in.
2069 (config_func): bring this up to date with the new pixbuf_scale
2072 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
2073 loading code so that poeple can diagnose problems better.
2075 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
2076 no longer allocates a new pixbuf, which make things nicer for the
2077 rest of the code. Unfortunately there is still a problem with
2078 scaling rgba images.
2080 1999-07-16 Mark Crichton <crichton@gimp.org>
2082 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
2083 calls gdk_pixbuf_scale. However, something is not working.
2084 N.B.: current pixmap is now stored in user_data with a key of
2087 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
