13 pointer increment out of the macro, because at least one
14 compiler (msvc 5.0) gets confused otherwise (applies the
17 * gdk_pixbuf.def : updated exports

28 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
29 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some

34 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
36 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
37 over to the new include flags AC_SUBST(). (Problem
38 pointed out by Mikael Hermansson.)

52 * gdk-pixdata.c: <string.h>
54 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
55 also leaking memory here from g_strdup_printf?)

65 installed API for applications that need to serialize/deserialize
66 on their own (gimp, BEAST).
68 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
69 program that can dump images in CSource format and Pixbuf
70 stream format. supports RLE encoding, MACRO formatting etc...
73 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
75 * Makefile.am: Actually update timestamps, so rules don't
78 2001-06-11 Havoc Pennington <hp@redhat.com>
80 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
81 already includes top_builddir
83 2001-06-08 Havoc Pennington <hp@redhat.com>
85 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
86 bogus g_return_if_fail
88 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
89 likely timeout resolution, set it to an arbitrarily-chosen short
91 Fixes bug #55953 from warmenhoven@yahoo.com
93 2001-06-07 Havoc Pennington <hp@redhat.com>
95 * Makefile.am: use Owen's new way of doing stampfiles/generated
98 2001-06-07 Havoc Pennington <hp@redhat.com>
100 * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path
102 2001-06-05 Havoc Pennington <hp@redhat.com>

107 2001-05-08 Havoc Pennington <hp@redhat.com>
109 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
110 and fix behavior to still subst color if the original image
113 2001-06-04 Havoc Pennington <hp@redhat.com>
115 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
118 2001-06-01 Havoc Pennington <hp@redhat.com>
120 Apply patch from sandmann@daimi.au.dk, with some tweaks.
121 Makes things a bit more robust, and adds test-loaders.c
122 which is good for finding further robustness bugs to fix.
124 * io-tiff.c: Try to work around libtiff suckiness a bit;
125 put a giant thread lock on the whole loader,
126 paranoically check both whether error handlers were called and
127 also whether functions return false. Handle case where width or
128 height is 0. Various cleanups.
130 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
132 (png_error_callback): apparently libpng expects you to longjmp out
135 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
136 (lzw_read_byte): change "Mail jrb if this fails" g_warning
138 (gif_get_lzw): check for out-of-memory
139 (gif_prepare_lzw): catch/report an error
140 (new_context): use try_malloc, since GifContext is nearly 70K
141 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
142 so we don't crash later.
144 * Makefile.am: Add test-loaders
146 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
149 2001-05-29 Darin Adler <darin@eazel.com>
151 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
153 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
155 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
156 fix up bmp decoder to:
157 - adds 16 bpp bmp support (bug #53884)
158 - adds OS/2 1.x format bmp support (bug #54964)
159 - adds 4 bpp RLE compressed bmp support
160 - adds 1 bpp colormap support
161 - fixes negative height (top down) bmp support
163 2001-05-25 Hans Breuer <hans@breuer.org>
165 * gdk_pixbuf.def : reflect Havoc's recent api change
167 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
169 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
172 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
174 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
176 2001-05-04 Havoc Pennington <hp@redhat.com>
178 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
179 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
182 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
183 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
184 confusion of using "src" instead of "p".
185 (pixops_composite_color_nearest): Use a more accurate (and
186 correct, to begin with) compositing method. This cures checks
187 showing through on images with no alpha.
189 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
192 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
194 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
195 area_updated signal to use signed ints. Removed animation-related
198 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
201 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
202 all the pesky details. Remove old frame-based API. Make
203 GdkPixbufAnimation an abstract base class, derived by the loaders.
205 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
207 * Makefile.am (LDADDS): Add $(MATH_LIB).
209 2001-04-18 Havoc Pennington <hp@redhat.com>
211 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
214 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
216 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
217 so we don't try to get <gtk/gtkobject.h> from standard search
220 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
221 add gdk-pixbuf-marshal.list to EXTRA_DIST.
222 take gdk-pixbuf-marshal.h out of _la sources.
224 2001-03-19 Tor Lillqvist <tml@iki.fi>
226 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
228 * gdk_pixbuf.def: Update.
230 * pixbufloader_*.def: Just export the fill_vtable functions now.
232 2001-03-18 Mike Kestner <mkestner@ameritech.net>
234 * make-inline-pixbuf.c (main): Added logic to remove output when
237 2001-03-14 Havoc Pennington <hp@redhat.com>
239 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
240 from gdk-pixbuf-marshal.h, fixes parallel makes.
242 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
244 * test-gdk-pixbuf.c: fixed includes.
246 2001-02-18 Havoc Pennington <hp@pobox.com>
248 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
249 (gdk_pixbuf_get_named_module): prepend underscore
250 (gdk_pixbuf_get_module): prepend underscore
252 2001-02-19 Havoc Pennington <hp@redhat.com>
254 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
256 2001-02-17 Havoc Pennington <hp@pobox.com>
258 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
260 2001-02-07 Alexander Larsson <alexl@redhat.com>
262 * io-xpm.c (free_buffer):
263 Use g_free, since the buffer is allocated with g_try_alloc().
265 2001-02-06 Christophe Merlet <redfox@eikonex.org>
267 * gdk-pixbuf-data.c: Fixes a minor typo.
269 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
271 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
272 we finally need the gobject->gruntime rename.
274 * *.c: scratched calls to g_type_init(), there's simply no point in
275 doing that, use gtk_init().
277 2001-02-01 Havoc Pennington <hp@pobox.com>
279 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
280 in struct to "priv" for C++
282 2001-01-31 Havoc Pennington <hp@pobox.com>
284 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
286 2001-01-26 Havoc Pennington <hp@redhat.com>
288 * gdk-pixbuf-io.c (mname): fix included modules case.
290 2001-01-22 Havoc Pennington <hp@redhat.com>
292 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
293 from gdk_pixbuf_load_module
295 2001-01-22 Havoc Pennington <hp@redhat.com>
297 * Makefile.am: Add built marshaller files to support
298 GdkPixbufLoader signals
300 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
301 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
302 module location, rather than acting as a fallback, because we are
303 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
305 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
307 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
308 from gtk, and add error to close(), because stop_load may do
309 parsing of the image.
311 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
313 * io-*.c: make individual operations static, and add fill_vtable
314 functions which are exported. Fix the collection of type warnings
315 that surfaced, including a number of functions that didn't
316 properly take a GError and some that weren't
317 const-correct. Involved adding error handling for a few loaders.
319 * gdk-pixbuf-io.h: Add error reporting to stop_load function
321 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
322 a function that fills in the GdkPixbufModule vtable, instead of
323 looking up all the image functions individually; this means we
324 can get type safety within modules for the loader functions.
325 Also it means you don't have to keep the statically compiled and
326 GModule versions in sync.
328 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
330 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
332 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
334 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
337 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
339 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
342 2001-01-20 John Harper <jsh@eazel.com>
344 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
345 collision between Xlib's RdBitF.c and io-tiff.c
347 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
350 [ merged from stable gdk-pixbuf module. Untested, but it
351 compiles, and works fine in the stable module ]
353 2001-01-18 Tor Lillqvist <tml@iki.fi>
355 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
356 g_win32_get_package_installation_subdirectory() function. No need
357 to include windows.h.
358 (gtk_win32_get_installation_directory): Remove this then.
360 2001-01-01 Havoc Pennington <hp@redhat.com>
362 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
363 @LIBTOOL_EXPORT_OPTIONS@
365 2000-12-30 Tor Lillqvist <tml@iki.fi>
367 * gdk_pixbuf.def: Update.
369 2000-12-16 Havoc Pennington <hp@pobox.com>
371 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
372 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
373 (gdk_pixbuf_frame_copy): new function
374 (gdk_pixbuf_frame_free): new function
375 (gdk_pixbuf_frame_get_type): new function
376 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
378 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
380 * Makefile.am: Add -avoid-version for all modules.
382 2000-11-13 Havoc Pennington <hp@redhat.com>
384 * io-png.c (png_simple_error_callback): fix error message to not
385 say "save" since it's used for loading
387 2000-11-11 Hans Breuer <Hans@Breuer.Org>
389 * gdk-pixbuf-io.c : Fix all function prototype macros for self
390 contained image handlers (!USE_G_MODULE). Files to save should
391 be opened in binary mode, fopen(s, "wb").
393 * io-xpm.c : added HAVE_UNISTD_H condition
395 2000-11-11 Tor Lillqvist <tml@iki.fi>
397 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
399 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
400 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
401 mktemp() and open()).
403 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
405 2000-11-01 Havoc Pennington <hp@pobox.com>
407 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
408 a pixbuf pointing to a subregion of another pixbuf.
410 2000-10-16 Tor Lillqvist <tml@iki.fi>
412 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
414 2000-10-16 Havoc Pennington <hp@redhat.com>
416 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
417 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
418 add error reporting here also
420 * make-inline-pixbuf.c (main): use GError
422 * io-xpm.c: include unistd.h
424 * gdk-pixbuf-util.c: include string.h
426 * io-*.c: add error reporting
428 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
431 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
433 * gdk-pixbuf-io.h: Add GError** to load_increment and load
436 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
437 a G_FILE_ERROR if we fail to write or close the file.
439 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
440 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
441 the GError naming rules. Add GError** to load functions.
443 2000-10-06 Havoc Pennington <hp@redhat.com>
445 * gdk-pixbuf.h: add GdkPixbufAlphaMode
447 2000-10-06 Havoc Pennington <hp@redhat.com>

507 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
508 xpm at least supports the progressive interface like the one in
509 io-tiff.c. This should be reimplemented as an actual progressive

588 inline pixbuf data and create a pixbuf from it.
590 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
592 2000-09-07 Tor Lillqvist <tml@iki.fi>
594 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
597 2000-08-12 Tor Lillqvist <tml@iki.fi>
599 * gdk_pixbuf.def: Add missing entry point.
601 2000-08-10 Havoc Pennington <hp@redhat.com>
603 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
604 (s/pixbuf_/pixbufloader_)
606 2000-08-02 Tor Lillqvist <tml@iki.fi>
612 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
614 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
615 one. Fix names of DLLs to have '-' instead of '_'.
617 2000-07-31 Elliot Lee <sopwith@redhat.com>
618 * io-wbmp.c: Some bug fixes - now tested to work.
620 2000-07-27 Elliot Lee <sopwith@redhat.com>
622 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
623 gdk_pixbuf_get_named_module() function to facilitate above change
624 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
625 Implement loader for WBMP format.
626 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
628 2000-07-23 Tor Lillqvist <tml@iki.fi>
633 * pixops/makefile.mingw.in
634 * pixbuf_*.def: New files.
637 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
639 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
640 New function, to get the GTK+ installation directory from
641 the Windows Registry, where the installation program
642 for whatever software includes GTK+ has stored it.
644 Used to avoid having hardcoding the directory where to look for
645 loaders. This function is needed by gtk, too, so it should
646 really be just in one place. Maybe a small static library
647 one level up from here?
649 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
650 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
651 Open file in binary mode. This *is* standard C. (No-op on Unix,
654 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
656 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
658 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
660 * pixops/*.S: The Gas from mingw32 doesn't like the .type
661 pseudo-op. Conditionalise on __MINGW32__, but probably
662 should conditionalise on Gas version instead? Or could we
663 do without .type on all systems?
665 * pixops/timescale.c: Use g_get_current_time()
666 instead of gettimeofday().
668 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
670 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
672 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
674 * gdk-pixbuf.c: Add <string.h> include.
676 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
678 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
679 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
680 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
681 use g_object_new() instead of g_type_create_instance() which
682 is a private function for fundamental type implementations.
684 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
686 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
687 soname scheme for gdk-pixbuf.
689 2000-06-21 Havoc Pennington <hp@pobox.com>
691 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
692 (i.e. derivation is not allowed, and there are no virtual methods
694 (gdk_pixbuf_preinit): Call g_type_init() here.
695 (gdk_pixbuf_init): Add a user-friendly init function, for users
696 of standalone gdk-pixbuf
698 * gdk-pixbuf-animation.c: Convert to GObject, in the same
699 way GdkPixbufAnimation was done.
701 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
702 gdk_pixbuf_finalize() from API, since these are broken and don't
703 make sense with new GObject stuff.
705 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
707 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
708 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
711 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
713 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
714 so I needed something to warm my thighs. Running plain infinite
715 loops on your laptop to make it hot is not very much fun. A demo
716 of the gdk-pixbuf scaling functions is way better, and looks
719 * configure.in (AC_OUTPUT): Added the demo Makefile.
721 * Makefile.am (SUBDIRS): Added the demo directory.
723 2000-06-09 Larry Ewing <lewing@helixcode.com>
725 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
726 setjmp for the png error handler. It seems setting the error
727 handling functions does not avoid the jump, and so not calling
728 setjmp was causing the incremental loader to jump into lala land.
729 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
730 not sure this one is actually required but the docs say it must be
731 set for every call to a png_* function.
732 Also changed the comment to reflect the fact that setting the
733 error handlers does _not_ avoid the longjmp.
735 2000-06-06 Larry Ewing <lewing@helixcode.com>
737 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
738 take frame offest into account when trying to calculate the
739 animation bbox. Also set the width to the width not the height.
740 (gdk_pixbuf_loader_animation_done): cycle over the frames to
741 calculate bbox because now we finally have all the offset
742 information for each frame.
744 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
746 * configure.in: add some gtk parameters to the
747 GDK_PIXBUF_LIB²S and GDK_PIXBUG_INCLUDEDIR vars. One more
748 fight in my crusade for strange prefix compile...
750 2000-05-30 Not Zed <NotZed@HelixCode.com>
752 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
753 Initialise the error handler exit routine to our own. Note this
754 means that every function that accesses the jpeg lib on this
755 object MUST do a setjmp.
756 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
757 lib for handling fatal error.
758 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
759 your applications dont quit if there's a jpeg error!
761 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
763 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
764 from Frank de Lange <frank@unternet.org>.
766 2000-05-09 Darin Adler <darin@eazel.com>
768 * gdk-pixbuf/test-gdk-pixbuf.c:
769 Fixed includes to get rid of accidental GNOME dependency.
771 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
772 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
774 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
776 * configure.in: Bumped version number to 0.8.0.
778 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
779 file was not being distributed.
781 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
783 2000-05-09 Darin Adler <darin@eazel.com>
785 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
786 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
787 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
788 formats to 32-bit formats to re-use the high bits of the color values
789 so that white maps to full white.
791 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
793 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
794 detailed information about the structure and algorithms
795 of pixops so people can fix it instead of breaking it.
797 2000-05-04 Darin Adler <darin@eazel.com>
799 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
800 (composite_pixel), (composite_line):
801 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
802 Now that Owen explained the algorithm, I think I implemented it
803 right for the cases where the destination pixbuf is not opaque.
804 The test does seem to confirm it.
806 2000-05-04 Darin Adler <darin@eazel.com>
808 * gdk-pixbuf/.cvsignore:
809 * gdk-pixbuf/Makefile.am:
810 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
811 (load_pixel), (simple_composite_test_one),
812 (simple_composite_test_one_type), (simple_composite_test), (main):
813 Added some tests of composite to highlight problems in the old
814 implementation. These tests run without any user interaction.
815 Just do "make check".
817 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
818 (composite_pixel), (composite_line): Fix composite to do a textbook
819 "A over B" composite. This was clearly the intent, and it was easy
820 to fix the code to do it. (Note to those that read my earlier tries
821 at a patch; this version fixes typos that were present in all
822 my patch attempts. I checked the final version by adding more tests.)
824 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
826 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
827 offset y coordinate accordining to render_y0.
829 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
832 2000-04-22 James Henstridge <james@daa.com.au>
834 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
835 package to the devel package. The only file installed in bin is
836 gdk-pixbuf-config, which belongs in -devel. This should allow having
837 multiple versions of the main gdk-pixbuf package installed.
839 2000-04-17 Karl Eichwalder <ke@suse.de>
841 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
842 Reported by Jens Finke.
844 2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
846 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
847 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
849 2000-04-13 James Henstridge <james@daa.com.au>
851 * configure.in: when performing the configure check to see if
852 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
853 rather than the other way round. Also, call AC_MSG_RESULT in the
854 even that dynamic modules were not supported.
856 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
858 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
859 hook to the last unref operation.
861 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
862 function to set the last unref handler for a pixbuf.
863 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
864 It calls the pixbuf's destroy notification function and frees the
865 GdkPixbuf structure itself.
866 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
869 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
870 for the last unref handler and its user data.
872 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
873 g_new0() to allocate the pixbuf.
875 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
876 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
877 was not specifying the `frame' argument.
879 * gdk-pixbuf/gdk-pixbuf-animation.c
880 (gdk_pixbuf_animation_get_width): Fixed docstring.
881 (gdk_pixbuf_animation_get_height): Likewise.
882 (gdk_pixbuf_animation_get_num_frames): Likewise.
883 (gdk_pixbuf_animation_get_frames): Likewise.
885 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
888 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
890 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
892 * doc/tmpl/refcounting.sgml: Updated with the information about
893 the last unref handler.
895 * doc/tmpl/*.sgml: Markup tweaks.
897 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
898 update the libtool version number for libgnomecanvaspixbuf as
900 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
901 as well, or the old ones won't work with the new stuff. Also,
902 renamed the modules as follows.
904 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
905 modules are called "libpixbufloader-<format>.so" instead of
906 "libpixbuf-<format>.so". They needed renaming so that the new
907 loaders won't overwrite the old ones; even with the versioning
908 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
911 2000-04-12 Paolo Molaro <lupus@debian.org>
913 * .cvsignore, src/.cvsignore: shut up cvs.
915 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
917 Most of this patch is based on a patch by Havoc Pennington
918 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
919 remove the libart dependency.
921 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
922 (GdkColorspace): New enum that for now only contains
924 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
925 notification function.
926 (GdkInterpType): New num with interpolation types.
928 * *.[ch]: Replace the libart stuff with our own stuff.
930 * pixops/*.[ch]: Likewise.
932 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
933 declarations of the GdkPixbuf structures.
935 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
937 (gdk_pixbuf_get_format): Constify.
938 (gdk_pixbuf_get_n_channels): Constify.
939 (gdk_pixbuf_get_has_alpha): Constify.
940 (gdk_pixbuf_get_bits_per_sample): Constify.
941 (gdk_pixbuf_get_pixels): Constify.
942 (gdk_pixbuf_get_width): Constify.
943 (gdk_pixbuf_get_height): Constify.
944 (gdk_pixbuf_get_rowstride): Constify.
946 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
949 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
950 bits_per_sample argument; currently only 8 bits per sample are
953 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
955 (gdk_pixbuf_frame_get_x_offset): New accessor.
956 (gdk_pixbuf_frame_get_y_offset): New accessor.
957 (gdk_pixbuf_frame_get_delay_time): New accessor.
958 (gdk_pixbuf_frame_get_action): New accessor.
960 * gdk-pixbuf/gdk-pixbuf-render.c
961 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
962 mask rectangle for pixbufs without an alpha channel, set the
963 *mask_return to NULL.
965 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
967 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
969 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
970 preconditions. Maybe we should also check for the colorspace,
971 bits per pixel, and such.
972 (gdk_pixbuf_composite): Likewise.
973 (gdk_pixbuf_composite_color): Likewise.
974 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
975 cannot allocate the new pixbuf.
976 (gdk_pixbuf_composite_color_simple): Likewise.
978 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
979 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
982 * gdk-pixbuf/io-bmp.c: Fix includes.
984 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
989 * configure.in: Removed checks for libart.
991 * gdk-pixbuf/Makefile.am: Removed references to libart.
992 (noinst_HEADERS): Added gdk-pixbuf-private.h.
994 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
995 the version number of the libtool library to indicate that this
996 definitely is not compatible with the old usage. I know you love
999 * configure.in: Bumped version number to 0.7.0.
1003 * gdk-pixbuf-config.in (--libs): We no longer require libart.
1005 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
1007 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
1009 2000-04-06 Jonathan Blandford <jrb@redhat.com>
1011 * gdk-pixbuf/testanimation.c (main): add more info to the
1012 testanimation frames.
1014 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
1016 * gdk-pixbuf/gdk-pixbuf-animation.c
1017 (gdk_pixbuf_animation_get_width): New accessor function.
1018 (gdk_pixbuf_animation_get_height): New accessor function.
1019 (gdk_pixbuf_animation_get_num_frames): New accessor function.
1020 (gdk_pixbuf_animation_get_frames): New accessor function.
1022 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
1024 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
1025 is private information, and the art_pixbuf will go away soon.
1027 2000-03-31 Mark Crichton <crichton@gimp.org>
1029 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
1030 and gdk_pixbuf_get_artpixbuf accessor functions.
1032 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
1034 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
1035 gboolean instead of int.
1037 2000-03-29 Radek Doulik <rodo@helixcode.com>
1039 * gdk-pixbuf/gdk-pixbuf-animation.c
1040 (gdk_pixbuf_animation_new_from_file): same as below
1042 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
1043 height in GdkPixbufAnimation
1045 2000-03-28 Radek Doulik <rodo@helixcode.com>
1047 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
1048 context->frame_done_func and context->anim_done_func to make
1049 progressive animation loading work
1051 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1052 added priv->pixbuf = NULL as pixbuf is now in frame (and to make
1053 gdk_pixbuf_loader_prepare happy)
1054 (gdk_pixbuf_loader_frame_done): update animation bbox
1056 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
1059 2000-03-27 Radek Doulik <rodo@helixcode.com>
1061 * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
1062 instead of width and height
1064 2000-03-27 Owen Taylor <otaylor@redhat.com>
1066 * gdk-pixbuf/pixops/pixops.c: Fix problem with
1067 precendence of >> and & which was keeping composite_color
1068 from working with non-gray images.
1070 2000-03-08 Jonathan Blandford <jrb@redhat.com>
1072 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.
1073 (gdk_pixbuf__gif_image_load_animation): free the context.
1075 2000-03-06 Arjan van de Ven <arjan@fenrus.demon.nl>
1077 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
1078 mis-interpretation of the Microsoft documentation. Now
1079 it can load .BMP files that are not generated by The Gimp
1082 2000-03-01 Mark Crichton <crichton@gimp.org>
1084 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
1085 fix the last auto* build bug (where we have libart, but no
1088 * gdk-pixbuf/Makefile.am: Same.
1090 2000-02-28 Matt Wilson <msw@redhat.com>
1092 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
1093 s/unsigned short/guint16/g, s/unsigned char/guint8/g
1095 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
1097 * README: We don't require libgif/ungif nor libXpm.
1099 * NEWS: This was outdated, so updated it.
1101 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
1103 * gdk-pixbuf.m4: Use the correct name for
1104 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing
1107 2000-02-21 Federico Mena Quintero <federico@helixcode.com>
1109 * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0.
1111 * doc/compiling.sgml: New appendix documenting the gdk-pixbuf
1112 library's particular options to configure.in.
1114 * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an
1117 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
1119 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
1120 Fixed typo in prototype name.
1122 * configure.in: Changed duplicated AC_MSG_CHECKING message to
1123 something more meaningful; now it is "checking whether dynamic

1518 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
1519 with a reference count of 1.
1521 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added

1524 * doc/tmpl/animation.sgml: Populated. It is still missing a

1547 1999-12-20 Jonathan Blandford <jrb@redhat.com>
1549 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
1550 correctly. Progressive loading needs some work, but that all
1551 needs doing from the gdk-pixbuf-loader end, not here.
1553 1999-12-17 Jonathan Blandford <jrb@redhat.com>
1555 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
1556 moved the file here. It seems natural to put this function here,
1557 as that's where the gdk_pixbuf_new_from_file function is, but it's
1558 still a little convoluted. The source files might be played with

1575 * gdk-pixbuf/gnome-canvas-pixbuf.c
1576 (gnome_canvas_pixbuf_class_init): Renamed arguments to
1577 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for

1607 Filled in body of function.
1608 (rgbconvert): Added GdkColormap parameter, and to all conversion
1610 (convert_real_slow): New function - should convert ANY visual/data
1611 format properly, but it aint fast. Used as a fallback when an
1612 optimised routine wont match.
1613 (rgbconvert): Do very specific tests on the data format to verify
1614 properly if the optimised version will do, otherwise use the
1615 fallback function for all other data formats.
1617 * gdk-pixbuf/Makefile.am: Re-enabled building of
1618 textpixbuf-drawable.
1620 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use

1634 checks and API definition. The body needs filling in and it needs
1635 to do the Right Thing(tm) for pixmaps plus the given colormap and
1636 windows and their own colormaps.
1638 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
1639 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
1641 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
1643 * doc/tmpl/from-drawables.sgml: Populated.

1655 reference counting for GdkPixbuf structures.
1657 1999-12-07 Martin Baulig <martin@home-of-linux.org>
1659 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
1660 include $(GNOME_LIBS) here.
1662 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
1664 Added missing "include <string.h>" to:

1669 1999-12-06 Federico Mena Quintero <federico@redhat.com>
1671 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
1674 1999-12-05 Federico Mena Quintero <federico@redhat.com>
1676 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
1677 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
1678 want, send me a patch to do the conditional stuff properly.
1679 Otherwise, please read the GNOME Programming Guidelines,
1680 especially the "CVS policies" section.
1682 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
1684 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
1686 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>

1691 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
1693 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
1694 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
1696 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
1698 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
1701 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
1702 (Windows Cursor files). These are identical to .ICO files,
1703 except for the signature and 2 extra fields for the hotspot.
1705 1999-12-03 Federico Mena Quintero <federico@redhat.com>
1707 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):

1713 explain this function better.
1715 1999-12-02 Federico Mena Quintero <federico@redhat.com>
1717 Source files moved from src/ to gdk-pixbuf/, to be consistent with
1720 * doc/Makefile.am: Modified for the new source directory.

1792 1999-11-29 Owen Taylor <otaylor@redhat.com>
1794 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
1795 Keep the mask around until after we draw ... since
1796 the GC changes aren't flushed to the X server until we
1797 draw, destroying it before that may result in BadPixmap
1800 1999-11-30 Havoc Pennington <hp@pobox.com>
1802 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
1804 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
1806 1999-11-29 Federico Mena Quintero <federico@redhat.com>
1808 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
1809 should be made conditional, not blindly commented out.
1811 1999-11-29 Jonathan Blandford <jrb@redhat.com>
1813 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
1814 handle .ico files. Cool.
1816 1999-11-24 Jonathan Blandford <jrb@redhat.com>
1818 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
1821 1999-11-24 James Henstridge <james@daa.com.au>
1823 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
1824 top builddir rather than src. This still builds fine, and does not
1825 get gtk-doc into an infinite loop when trying to find all the source
1828 1999-11-23 Jonathan Blandford <jrb@redhat.com>
1830 * Removed #PRAGMA } from headers. Also, make compile if you don't
1831 have it installed, already.
1833 1999-11-22 Federico Mena Quintero <federico@redhat.com>
1835 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
1836 temporary buffer to the size of the interesction of the bounding
1837 box and the expose area, not the whole expose area. This speeds
1840 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
1841 not paint black on the mask, since we already cleared it in a
1842 single gdk_draw_rectangle() operation.
1844 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
1846 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
1848 1999-11-22 Havoc Pennington <hp@pobox.com>
1850 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
1851 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
1852 dependencies to LIBADD variables for loadable modules. Necessary
1853 for a Java dynamic loading thing to be able to figure it out.
1855 1999-11-22 Havoc Pennington <hp@pobox.com>
1857 * src/io-png.c (image_load_increment): Call the update_area
1858 callback depending on the number of rows loaded in this increment.
1860 * src/testpixbuf.c (main): slow down the progressive load demo
1862 1999-11-16 Havoc Pennington <hp@pobox.com>
1864 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
1866 1999-11-22 Jonathan Blandford <jrb@redhat.com>
1868 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
1869 for srcdir != buildir != . Beats me why; I can't figure it out.
1870 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
1872 1999-11-21 Jonathan Blandford <jrb@redhat.com>
1874 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
1875 <arjan@fenrus.demon.nl>
1877 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
1879 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
1880 Rework/reorder of the code. Each case has been separated into
1881 another function; its big but it should be quick.
1882 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
1883 opaque alpha information. Not all depths/formats have been
1884 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
1886 1999-11-17 Larry Ewing <lewing@gimp.org>
1888 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
1889 implement the bounds method correctly.
1890 (compute_viewport_affine): compute the affine need to fit the
1891 image within the viewport given by the args.
1892 (compute_render_affine): call compute_viewport_affine.
1894 1999-11-16 Havoc Pennington <hp@pobox.com>
1896 * src/gdk-pixbuf-drawable.h: Use includes from the current
1897 directory, not the system directory.
1899 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
1901 * src/testpixbuf-drawable.c: use includes from the current directory
1902 rather then from the system include directory as gdk-pixbuf
1903 includes are not yet installed when this is compiled.
1905 1999-11-13 Cody Russell <bratsche@dfw.net>
1906 * src/testpixbuf-drawable.c: Added a test program for drawable
1909 * src/Makefile.am: Build testpixbuf-drawable.

1929 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
1930 correctly. Patch from Arjan to do so.
1932 1999-11-10 Michael Fulbright <drmike@redhat.com>
1934 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM

1955 1999-11-09 Michael Fulbright <drmike@redhat.com>
1957 * src/testpixbuf.c: Fixed it to use timeout to read from file
1958 for progressive loading. Set TBF_KBPS=n, where n is the number of
1959 kilobytes/second to simulate in downloading. n has to be an integer.
1961 * src/io-jpeg.c: Slight cosmetic cleanup.
1963 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
1964 PBM loading has a similar problem and will address tomorrow.
1966 1999-11-09 Havoc Pennington <hp@pobox.com>
1968 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
1969 gdk-pixbuf-drawable stuff.
1971 1999-11-09 Federico Mena Quintero <federico@redhat.com>

1975 1999-11-09 Michael Fulbright <drmike@redhat.com>
1977 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
1978 all types of PNM files now.
1980 * src/io-jpeg.c (image_load_increment): Figured out problem with
1981 loading Progressive JPEG's progressively (say that 10 times fast).
1982 Currently for Progressive JPEG's the entire image is loaded before
1983 it is displayed. libjpeg supports a fancier mechanism which I may
1986 With these changes all JPEG formats appear to load properly for me.
1988 1999-11-08 Jonathan Blandford <jrb@redhat.com>
1990 * src/io-ras.c (image_load_increment): Final patch from Arjan.
1991 Seems to do progressive loading.
1993 1999-11-08 Michael Fulbright <drmike@redhat.com>
1995 * src/io-pnm.c image_load (): Fixed so we do not create a separate
1996 pixel buffer when reading in image - we reuse the pixel data in
1997 the GdkPixbuf structure instead.
1999 1999-11-08 Michael Fulbright <drmike@redhat.com>
2001 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
2002 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
2003 I can't seem to find a utility to convert into this format.
2004 Next is to add progressive loading support for the PNM format.
2006 1999-11-07 Federico Mena Quintero <federico@redhat.com>
2008 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation

2018 * src/io-ras.c (image_load): new file from Arjan van de Ven
2019 <arjan@fenrus.demon.nl> to begin the ras loader.
2021 1999-11-05 Federico Mena Quintero <federico@redhat.com>

2057 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
2058 this function vs. gdk_pixbuf_render_to_drawable().
2060 1999-11-04 Havoc Pennington <hp@pobox.com>
2062 * configure.in: Use libart-config correctly; find gnome-config
2063 separately. Fix GNOME_LIBS to be correct in "no gnome installed
2066 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
2069 Patch untested in the inside-gnome-libs case, I need to commit
2070 then check out to the gnome-libs I'm using.

2173 1999-11-03 Michael Fulbright <drmike@redhat.com>
2175 * src/io-jpg.c (image_load_increment): Fixed code which moved
2176 buffer around as new data comes in to work properly. JPEG progressive
2177 loading should be working now except for grayscale JPEG's, which I
2178 will look into next.
2180 1999-11-03 <sopwith@redhat.com>
2181 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
2182 Also put dot printing back in.
2184 1999-11-03 <jrb@redhat.com>
2186 * src/io-gif.c (gif_get_extension): Read 'til the next empty block

2201 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
2203 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2205 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
2206 It's a little slow though. )-:
2208 1999-11-02 Elliot Lee <sopwith@redhat.com>
2209 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
2210 write/load_increment operations const-correct.
2212 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2214 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
2215 Implemented the ::point() method. We do a simple containment test
2216 instead of a full distance calculation since the canvas is going
2217 to change to that scheme, anyways.
2219 1999-11-02 Elliot Lee <sopwith@redhat.com>
2221 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
2222 that are read from the input file.
2224 1999-11-02 Larry Ewing <lewing@gimp.org>
2226 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
2228 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
2231 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2233 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
2234 affine computation code from ::draw() to here, since it is needed
2235 by ::point() as well.
2237 1999-11-02 Elliot Lee <sopwith@redhat.com>
2239 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
2240 three functions, and eliminate duplication of code from write()
2241 and close(). Also fix bug where the 128-byte header was being
2244 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2245 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
2246 bounding box computation.
2248 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2250 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
2251 Drawing affines seem to work. Bounding box is fubared. ::point()
2252 is not implemented. This is a work in progress.
2254 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
2257 * configure.in: Sigh. We need to link in libgnomeui for the
2258 canvas stuff. This mess will disappear when gdk-pixbuf gets
2259 folded into gnome-libs.
2261 1999-10-30 Jonathan Blandford <jrb@redhat.com>
2263 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
2264 the right size, at a minimum, even if the image is squished and
2266 (ReadImage): lets get the offset right. This will let transparent
2269 1999-10-29 Michael Fulbright <drmike@redhat.com>
2271 * src/io-jpeg.c: image_load_increment(): Fixed bug when
2272 image width was not a multiple of 4 - always use the
2273 gdk_pixbuf rowstride to increment pointers!
2275 1999-10-29 Michael Fulbright <drmike@redhat.com>
2277 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
2278 Currently does not handle either progressive jpeg files (jpeg
2279 files with multiple scans at different quality settings), but
2280 I plan on adding this support soon. These are fairly rare in
2281 my experience, so it shouldn't slow people down too much.
2282 Grayscale jpegs also don't work but that should be easy to fix.
2284 1999-10-29 Michael Fulbright <drmike@redhat.com>
2286 * src/testpixbuf.c: Added title to windows so you can identify
2287 progressive and file windows.
2289 1999-10-29 Michael Fulbright <drmike@redhat.com>
2291 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
2292 load the image handler when we determine the image type.
2294 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
2295 previously static function load_image_handler () to
2296 a public function gdk_pixbuf_load_module (). It is needed in
2297 gdk-pixbuf-loader.c to load image handler modules. This function
2298 is different from gdk_pixbuf_get_module (), which only returns
2299 a reference to the required handler, because it actually loads
2300 the handler into memory. Both actions should possibly be combined
2301 in a convenience function since one w/o the other doesn't seem to
2304 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2306 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
2309 1999-10-28 Federico Mena Quintero <federico@redhat.com>
2311 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
2312 function to render a portion of a pixbuf to a drawable. Ignores
2313 alpha information and takes in a GC.
2314 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
2315 portion of a pixbuf to a drawable. It automatically creates a GC
2316 and a clipping mask for alpha pixbufs.
2318 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2320 * src/gdk-pixbuf.h: turned convenience macros into convenience
2321 functions so some error checking could be added.
2323 * src/io-tiff.c (image_load_increment): started work on the tiff
2324 non-incremental loader.
2325 (image_begin_load): Finished the incremental loader.
2327 * src/io-gif.c (image_load_increment): started work on the gif
2330 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
2332 1999-10-27 Federico Mena Quintero <federico@redhat.com>
2334 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
2335 function to threshold a pixbuf's alpha channel into a bitmap.
2337 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
2338 contemplate future extensions to ArtPixBuf's formats.
2340 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
2342 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
2343 macros to fetch the ArtPixBuf's fields.
2345 1999-10-27 Havoc Pennington <hp@pobox.com>
2347 * src/testpixbuf.c (main): Display the progressive load
2349 * src/io-png.c (setup_png_transformations): Break transformation
2350 code into separate function
2351 (png_info_callback): Use setup_png_transformations
2353 1999-10-27 Havoc Pennington <hp@pobox.com>
2355 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
2356 properly whether the XPM module has already been loaded
2357 (gdk_pixbuf_new_from_file): Check properly if loader module
2358 was already loaded (was checking if load symbol was present
2359 in order to decide whether to re-load; should check module !=
2360 NULL, then load != NULL)
2361 (image_handler_load): Check in present working directory,
2362 makes it easier to debug for now
2363 (file_formats): This array initializer was seriously on crack,
2364 was assigning a function pointer to a GModule*
2366 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
2368 1999-10-27 Havoc Pennington <hp@pobox.com>
2370 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_finalize):
2371 Fix typo that prevented compilation
2372 (gdk_pixbuf_loader_destroy): ditto
2374 1999-10-27 Federico Mena Quintero <federico@redhat.com>
2376 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
2377 GdkPixbufLoader, not a GtkObject.
2378 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
2379 (gdk_pixbuf_loader_get_type): Documented.
2380 (gdk_pixbuf_loader_class_init): Initialize the parent class
2382 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
2383 class destroy function.
2384 (gdk_pixbuf_loader_new): Documented.
2385 (gdk_pixbuf_loader_finalize): Call the parent class finalize
2387 (gdk_pixbuf_loader_write): Use size_t for count.
2389 1999-10-27 Michael Fulbright <drmike@redhat.com>
2391 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
2392 logic so we only try to close loader if it wasn't previously closed.
2394 1999-10-27 Michael Fulbright <drmike@redhat.com>
2396 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of

2423 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
2425 1999-10-22 Havoc Pennington <hp@pobox.com>
2427 * src/io-xpm.c (mem_buffer): Clean up stupid
2428 increment-inside-array-dereference thing
2430 * src/testpixbuf.c: Add XPM data tests.
2432 * src/io-xpm.c: Make the XPM data buffer const, fix const
2433 correctness throughout the code.
2435 1999-10-22 Havoc Pennington <hp@pobox.com>
2437 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

2445 function, loads pixbuf from xpm data
2446 (image_handler_load): Add g_return_if_fail() to ensure the same
2447 module isn't loaded twice. Add g_module_symbol() to scan for XPM
2450 1999-10-22 Federico Mena Quintero <federico@redhat.com>
2452 * src/io-png.c (image_load): Patch from Kristian Hogsberg
2453 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
2454 buffers; the rows can be read in directly into the main pixel
2457 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2459 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
2461 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2463 * configure.in: Bumped version number to 0.3.
2465 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
2466 version number for the library.
2468 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2470 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
2471 all memory management of the buffer is done by libart.
2473 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
2474 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
2476 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
2477 terms of the libart functions. Removed the old code.
2479 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
2480 symbols. Saving will not be implemented in GdkPixbuf.
2482 * src/io-gif.c: Removed the saving stub.
2483 (image_load): Fixed memory management to fail gracefully if we run
2484 out of memory while loading the image. Close the gif file when we
2485 are done. This still needs more error handling for the DGif
2488 * src/io-jpeg.c (image_load): Some robustness fixes.
2490 * src/io-png.c: Removed the saving stuff.
2491 (image_load): Some memory management fixes.
2493 * src/io-tiff.c (image_load): Ditto.

2501 * autogen.sh: use subautogen.sh
2503 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2505 * src/*: Reindented to use the GNOME Indentation. Renamed
2506 GdkPixBuf to GdkPixbuf, for consistency with the function names
2507 (and it is also easier to type) :-)
2509 1999-10-18 Havoc Pennington <hp@pobox.com>
2511 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
2513 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
2515 1999-10-18 Havoc Pennington <hp@pobox.com>
2517 * Makefile.am (SUBDIRS): Remove "macros"
2519 * configure.in: Don't use GNOME_INIT, handle case where we are
2520 inside gnome-libs. AM_PATH_GTK for the GIF test
2522 * src/Makefile.am: Change flags to work without libgnomeui,
2523 comment out testpixbuf for now
2525 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2527 * configure.in: Use $GTK_LIBS as the extra libs when checking for
2528 libgif/libungif, as they need the X libraries. Fixes bug #2472.
2530 1999-10-10 Cody Russell <bratsche@dfw.net>
2531 * src/gdk-pixbuf-drawable.c: core function now determines whether
2532 the requested geometry is on screen or not, and if some is not
2533 then the request is clamped to geometry that is on the screen.
2535 Changed 'pixbuf' to 'art_pixbuf' in core function.
2537 1999-10-08 Michael Fulbright <drmike@redhat.com>
2539 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.
2541 * src/testpifbuf: Changed test program to display cdrom from rgb data
2542 if no filename given to test program.
2544 1999-10-07 Cody Russell <bratsche@dfw.net>
2545 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
2546 them, but I wrote them).
2548 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
2551 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
2552 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

2572 * src/io-tiff.c (image_load): ditto + fix leak
2574 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
2575 crashes this module ( add warning :-)
2577 * src/io-bmp.c (image_load): ditto.
2579 * src/io-gif.c (image_load): ditto.
2581 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
2583 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
2584 it doesn't crash scaling with alpha.
2586 1999-09-17 Federico Mena Quintero <federico@redhat.com>
2588 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
2590 * src/io-gif.c (image_load): Likewise.
2592 * src/io-jpeg.c (image_load): Likewise.
2594 * src/io-png.c (image_load): Likewise.
2596 * src/io-tiff.c (image_load): Likewise.

2609 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
2610 to unallocated memory (row_ptr), and fixed its type as well. Take
2611 into account the ArtPixbuf's rowstride when assigning the row
2614 * src/gdk-pixbuf.c: Fixup includes.
2616 * src/gdk-pixbuf-io.c: Likewise.
2618 Sat Jul 31 19:19:47 CEST 1999

2621 * src/io-png.c: Fixed two obvious C syntax bugs
2623 1999-07-29 Mark Crichton <crichton@gimp.org>
2625 * src/io-png.c (image_save): Added PNG saving function
2627 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
2628 image_save(GdkPixBuf *p, FILE *f, ...)
2631 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
2633 * src/Makefile.am (*_LIB): Only build the relevant loaders which
2634 require extra libraries if we actually have those libraries.
2636 1999-07-23 Richard Hestilow <hestgray@ionet.net>
2638 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
2639 * gdk_pixbufConf.sh.in: Added for gnome-config

2643 1999-07-20 Mark Crichton <crichton@gimp.org>
2645 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
2646 calculation needs to be done.
2648 1999-07-18 Larry Ewing <lewing@gimp.org>
2653 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
2654 error cases but one or two in the common case. There are probably
2655 a few small ones left.
2657 1999-07-18 Mark Crichton <crichton@gimp.org>
2659 * configure.in: removed version.h.
2661 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
2664 1999-07-17 Mark Crichton <crichton@gimp.org>
2666 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
2667 (gdk_pixbuf_rotate): Added pixbuf rotation code.

2670 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
2673 1999-07-16 Larry Ewing <lewing@gimp.org>
2675 * src/testpixbuf.c (expose_func): reverted the expose everything
2676 changes, I'm not sure why these went in.
2677 (config_func): bring this up to date with the new pixbuf_scale
2680 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
2681 loading code so that poeple can diagnose problems better.
2683 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
2684 no longer allocates a new pixbuf, which make things nicer for the
2685 rest of the code. Unfortunately there is still a problem with
2686 scaling rgba images.
2688 1999-07-16 Mark Crichton <crichton@gimp.org>
2690 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
2691 calls gdk_pixbuf_scale. However, something is not working.
2692 N.B.: current pixmap is now stored in user_data with a key of
2695 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
2696 Something is still borked, however.

2709 handler for testpixbuf
2711 1999-07-13 Mark Crichton <crichton@gimp.org>
2713 * configure.in: Fixed GIF check. Replaced " with '
