7 Mon Sep 17 11:49:02 2001 Owen Taylor <otaylor@redhat.com>
9 * pixops/*: Mirror GdkInterpType to PixopsInterpType
10 to avoid including gdk-pixbuf headers.
12 2001-09-16 James Henstridge <james@daa.com.au>
14 * .cvsignore: add generated files to ignore list.
16 * gdk-pixbuf.h: include gdk-pixbuf-enum-types.h

20 Fri Sep 14 23:22:12 2001 Matthias Clasen <matthiasc@poet.de>
22 * io-pnm.c (pnm_read_header): Use GDK_PIXBUF_ERROR_CORRUPT_IMAGE,
23 not GDK_PIXBUF_ERROR_HEADER_CORRUPT. (#58308)
25 Fri Sep 14 22:53:45 2001 Matthias Clasen <matthiasc@poet.de>

43 - one invalid tiff (sandmann@daimi.au.dk
45 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
47 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
48 fail - detect it when it happens
50 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
53 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
56 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
58 * Makefile.am: don't used BUILT_SOURCES to build marshal
59 files, as in conjunction with stamp files, this can
60 lead to endless rebuilding loops.
62 Tue Sep 4 00:22:07 2001 Owen Taylor <otaylor@redhat.com>
64 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1

83 area information. (#52002)
85 Tue Aug 28 20:03:43 2001 Matthias Clasen <matthiasc@poet.de>
87 * test-loaders.c (test_loader): Catch errors at close time.
88 * test-loaders.c (main): Remove C++ comments.
90 2001-08-21 Matthias Clasen <matthiasc@poet.de>
92 * Makefile.am, gdk-pixbuf-io.c, pixbufloader_tga.def,
93 io-tga.c: Add tga loader, patch by Nicola Girardi. (#56067)
95 2001-08-20 Matthias Clasen <matthiasc@poet.de>
97 * test-images.h, test-loaders.c: Add ico and wbmp tests.
98 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): Fail with a suitable
99 error if buffer allocation fails.
100 * io-ico.c: Make .ICO loader more robust.
101 All of these are due to sandmann@daimi.au.dk (#50187)
103 2001-08-19 Sven Neumann <sven@gimp.org>
105 * pixops/pixops.c: applied some simple but effective optimizations
106 to pixops_composite_nearest() and pixops_composite_color_nearest().
108 2001-08-07 Sven Neumann <sven@gimp.org>
110 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
111 function, so that's what I did.
113 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
115 * gdk-pixdata.c: Fix a typo.
117 2001-07-30 Hans Breuer <hans@breuer.org>

120 * makefile.msc : use it to complete the build
122 2001-07-20 Hans Breuer <hans@breuer.org>
124 * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
125 pointer increment out of the macro, because at least one
126 compiler (msvc 5.0) gets confused otherwise (applies the
129 * gdk_pixbuf.def : updated exports
131 * makefile.msc : reflect gdk-pixbuf-csource changes
133 2001-07-17 Darin Adler <darin@bentspoon.com>
135 * gdk-pixbuf-csource.c: Add missing <stdlib.h> include.
136 * io-png.c: (setup_png_transformations): Add ifdef so we compile
137 without warnings with G_DISABLE_CHECKS on.
138 * io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
140 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
141 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
142 unused locals and add an initial value to quiet the compiler's
143 unintialized variable warning.
144 * pixops/pixops.c: Put an ifdef around some dead code.
146 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
148 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
149 over to the new include flags AC_SUBST(). (Problem
150 pointed out by Mikael Hermansson.)
152 2001-06-29 Havoc Pennington <hp@redhat.com>
154 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): fix for
157 Thu Jun 28 21:54:19 2001 Owen Taylor <otaylor@redhat.com>
159 * make-inline-pixbuf.c test-gdk-pixbuf.c test-loaders.c

164 * gdk-pixdata.c: <string.h>
166 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
167 also leaking memory here from g_strdup_printf?)
169 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
171 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
173 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
174 instead from gdk_pixbuf_new_from_inline().
176 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
177 installed API for applications that need to serialize/deserialize
178 on their own (gimp, BEAST).
180 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
181 program that can dump images in CSource format and Pixbuf
182 stream format. supports RLE encoding, MACRO formatting etc...
185 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
187 * Makefile.am: Actually update timestamps, so rules don't
190 2001-06-11 Havoc Pennington <hp@redhat.com>
192 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
193 already includes top_builddir
195 2001-06-08 Havoc Pennington <hp@redhat.com>
197 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
198 bogus g_return_if_fail
200 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
201 likely timeout resolution, set it to an arbitrarily-chosen short
203 Fixes bug #55953 from warmenhoven@yahoo.com
205 2001-06-07 Havoc Pennington <hp@redhat.com>
207 * Makefile.am: use Owen's new way of doing stampfiles/generated
210 2001-06-07 Havoc Pennington <hp@redhat.com>
212 * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path
214 2001-06-05 Havoc Pennington <hp@redhat.com>
216 * test-loaders.c (main): use putenv not setenv, reported by
219 2001-05-08 Havoc Pennington <hp@redhat.com>
221 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
222 and fix behavior to still subst color if the original image
225 2001-06-04 Havoc Pennington <hp@redhat.com>
227 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
230 2001-06-01 Havoc Pennington <hp@redhat.com>
232 Apply patch from sandmann@daimi.au.dk, with some tweaks.
233 Makes things a bit more robust, and adds test-loaders.c
234 which is good for finding further robustness bugs to fix.
236 * io-tiff.c: Try to work around libtiff suckiness a bit;
237 put a giant thread lock on the whole loader,
238 paranoically check both whether error handlers were called and
239 also whether functions return false. Handle case where width or
240 height is 0. Various cleanups.
242 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
244 (png_error_callback): apparently libpng expects you to longjmp out
247 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
248 (lzw_read_byte): change "Mail jrb if this fails" g_warning
250 (gif_get_lzw): check for out-of-memory
251 (gif_prepare_lzw): catch/report an error
252 (new_context): use try_malloc, since GifContext is nearly 70K
253 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
254 so we don't crash later.
256 * Makefile.am: Add test-loaders
258 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
261 2001-05-29 Darin Adler <darin@eazel.com>
263 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
265 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
267 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
268 fix up bmp decoder to:
269 - adds 16 bpp bmp support (bug #53884)
270 - adds OS/2 1.x format bmp support (bug #54964)
271 - adds 4 bpp RLE compressed bmp support
272 - adds 1 bpp colormap support
273 - fixes negative height (top down) bmp support
275 2001-05-25 Hans Breuer <hans@breuer.org>
277 * gdk_pixbuf.def : reflect Havoc's recent api change
279 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
281 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
284 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
286 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
288 2001-05-04 Havoc Pennington <hp@redhat.com>
290 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
291 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
294 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
295 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
296 confusion of using "src" instead of "p".
297 (pixops_composite_color_nearest): Use a more accurate (and
298 correct, to begin with) compositing method. This cures checks
299 showing through on images with no alpha.
301 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
304 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
306 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
307 area_updated signal to use signed ints. Removed animation-related
310 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
313 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
314 all the pesky details. Remove old frame-based API. Make
315 GdkPixbufAnimation an abstract base class, derived by the loaders.
317 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
319 * Makefile.am (LDADDS): Add $(MATH_LIB).
321 2001-04-18 Havoc Pennington <hp@redhat.com>
323 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
326 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
328 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
329 so we don't try to get <gtk/gtkobject.h> from standard search
332 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
333 add gdk-pixbuf-marshal.list to EXTRA_DIST.
334 take gdk-pixbuf-marshal.h out of _la sources.
336 2001-03-19 Tor Lillqvist <tml@iki.fi>
338 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
340 * gdk_pixbuf.def: Update.
342 * pixbufloader_*.def: Just export the fill_vtable functions now.
344 2001-03-18 Mike Kestner <mkestner@ameritech.net>
346 * make-inline-pixbuf.c (main): Added logic to remove output when
349 2001-03-14 Havoc Pennington <hp@redhat.com>
351 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
352 from gdk-pixbuf-marshal.h, fixes parallel makes.
354 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
356 * test-gdk-pixbuf.c: fixed includes.
358 2001-02-18 Havoc Pennington <hp@pobox.com>
360 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
361 (gdk_pixbuf_get_named_module): prepend underscore
362 (gdk_pixbuf_get_module): prepend underscore
364 2001-02-19 Havoc Pennington <hp@redhat.com>
366 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
368 2001-02-17 Havoc Pennington <hp@pobox.com>
370 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
372 2001-02-07 Alexander Larsson <alexl@redhat.com>
374 * io-xpm.c (free_buffer):
375 Use g_free, since the buffer is allocated with g_try_alloc().
377 2001-02-06 Christophe Merlet <redfox@eikonex.org>
379 * gdk-pixbuf-data.c: Fixes a minor typo.
381 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
383 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
384 we finally need the gobject->gruntime rename.
386 * *.c: scratched calls to g_type_init(), there's simply no point in
387 doing that, use gtk_init().
389 2001-02-01 Havoc Pennington <hp@pobox.com>
391 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
392 in struct to "priv" for C++
394 2001-01-31 Havoc Pennington <hp@pobox.com>
396 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
398 2001-01-26 Havoc Pennington <hp@redhat.com>
400 * gdk-pixbuf-io.c (mname): fix included modules case.
402 2001-01-22 Havoc Pennington <hp@redhat.com>
404 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
405 from gdk_pixbuf_load_module
407 2001-01-22 Havoc Pennington <hp@redhat.com>
409 * Makefile.am: Add built marshaller files to support
410 GdkPixbufLoader signals
412 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
413 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
414 module location, rather than acting as a fallback, because we are
415 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
417 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
419 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
420 from gtk, and add error to close(), because stop_load may do
421 parsing of the image.
423 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
425 * io-*.c: make individual operations static, and add fill_vtable
426 functions which are exported. Fix the collection of type warnings
427 that surfaced, including a number of functions that didn't
428 properly take a GError and some that weren't
429 const-correct. Involved adding error handling for a few loaders.
431 * gdk-pixbuf-io.h: Add error reporting to stop_load function
433 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
434 a function that fills in the GdkPixbufModule vtable, instead of
435 looking up all the image functions individually; this means we
436 can get type safety within modules for the loader functions.
437 Also it means you don't have to keep the statically compiled and
438 GModule versions in sync.
440 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
442 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
444 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
446 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
449 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
451 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
454 2001-01-20 John Harper <jsh@eazel.com>
456 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
457 collision between Xlib's RdBitF.c and io-tiff.c
459 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
462 [ merged from stable gdk-pixbuf module. Untested, but it
463 compiles, and works fine in the stable module ]
465 2001-01-18 Tor Lillqvist <tml@iki.fi>
467 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
468 g_win32_get_package_installation_subdirectory() function. No need
469 to include windows.h.
470 (gtk_win32_get_installation_directory): Remove this then.
472 2001-01-01 Havoc Pennington <hp@redhat.com>
474 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
475 @LIBTOOL_EXPORT_OPTIONS@
477 2000-12-30 Tor Lillqvist <tml@iki.fi>
479 * gdk_pixbuf.def: Update.
481 2000-12-16 Havoc Pennington <hp@pobox.com>
483 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
484 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
485 (gdk_pixbuf_frame_copy): new function
486 (gdk_pixbuf_frame_free): new function
487 (gdk_pixbuf_frame_get_type): new function
488 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
490 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
492 * Makefile.am: Add -avoid-version for all modules.
494 2000-11-13 Havoc Pennington <hp@redhat.com>
496 * io-png.c (png_simple_error_callback): fix error message to not
497 say "save" since it's used for loading
499 2000-11-11 Hans Breuer <Hans@Breuer.Org>
501 * gdk-pixbuf-io.c : Fix all function prototype macros for self
502 contained image handlers (!USE_G_MODULE). Files to save should
503 be opened in binary mode, fopen(s, "wb").
505 * io-xpm.c : added HAVE_UNISTD_H condition
507 2000-11-11 Tor Lillqvist <tml@iki.fi>
509 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
511 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
512 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
513 mktemp() and open()).
515 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
517 2000-11-01 Havoc Pennington <hp@pobox.com>
519 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
520 a pixbuf pointing to a subregion of another pixbuf.
522 2000-10-16 Tor Lillqvist <tml@iki.fi>
524 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
526 2000-10-16 Havoc Pennington <hp@redhat.com>
528 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
529 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
530 add error reporting here also
532 * make-inline-pixbuf.c (main): use GError
534 * io-xpm.c: include unistd.h
536 * gdk-pixbuf-util.c: include string.h
538 * io-*.c: add error reporting
540 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
543 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
545 * gdk-pixbuf-io.h: Add GError** to load_increment and load
548 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
549 a G_FILE_ERROR if we fail to write or close the file.
551 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
552 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
553 the GError naming rules. Add GError** to load functions.
555 2000-10-06 Havoc Pennington <hp@redhat.com>
557 * gdk-pixbuf.h: add GdkPixbufAlphaMode
559 2000-10-06 Havoc Pennington <hp@redhat.com>
561 This entry is a summary of the merged-in changes from 1.0.
562 Relevant original ChangeLog entries are spliced in after
563 this entry; the files they refer to are from the 1.0

575 * io-pnm.c: new version from 1.0 tree
577 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): sync from 1.0, use
580 * io-gif.c (lzw_read_byte): sync from 1.0, change a g_error to
582 (gif_get_next_step): return 0 here, sync from 1.0
584 * gdk-pixbuf-util.c: sync email address change for Cody
587 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
589 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
590 last nights code was still "broken". Should now properly handle
591 all error conditions gracefully.
593 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
595 * gdk-pixbuf/io-pnm.c: Rewrote.
597 2000-09-09 Federico Mena Quintero <federico@helixcode.com>
599 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
600 the correct dest offset.
602 2000-08-25 Federico Mena Quintero <federico@helixcode.com>
604 * gdk-pixbuf/io-xpm.c: #include <unistd.h>
606 2000-08-05 Larry Ewing <lewing@helixcode.com>
608 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
610 * gdk-pixbuf/io-xpm.c: same as above.
612 2000-07-26 Michael Meeks <michael@helixcode.com>
614 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
617 2000-07-21 Larry Ewing <lewing@helixcode.com>
619 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
620 xpm at least supports the progressive interface like the one in
621 io-tiff.c. This should be reimplemented as an actual progressive
624 2000-07-19 Jonathan Blandford <jrb@redhat.com>
626 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
628 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
629 meeks to handle errors better.
631 2000-10-07 Tor Lillqvist <tml@iki.fi>
634 * pixbufloader_jpeg.def
635 * pixbufloader_png.def: Add new entry points.
637 * makefile.mingw.in: Use libintl.
639 2000-10-06 Havoc Pennington <hp@redhat.com>
641 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
642 consistent with gdk_pixbuf_loader_new_with_type().
643 Return runtime error if a module is missing.
645 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
647 2000-10-05 Havoc Pennington <hp@redhat.com>
649 Pixbuf saving, patch from David Welton.
651 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
652 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
654 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf
656 * io-png.c (gdk_pixbuf__png_image_save): PNG save routine.
658 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): JPEG save routine.
660 * gdk-pixbuf-io.c (gdk_pixbuf_save):
661 (gdk_pixbuf_savev): Implement pixbuf saving routines
663 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
666 * gdk-pixbuf.h: Add public save routines; add pixbuf error
669 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
671 2000-10-05 Dan Winship <danw@helixcode.com>
673 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
674 all three of these files are the JPEG image loader. (From
677 2000-10-03 Tor Lillqvist <tml@iki.fi>
679 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
680 gdk-pixbuf's version number in the rule for makefile.mingw itself.
682 * gdk_pixbuf.def: Add new entry points.
684 2000-09-26 Havoc Pennington <hp@redhat.com>
686 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
687 function here, instead of putting it in a private GTK+ file.
689 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
690 enum here for the known formats of inlined pixbufs.
691 Also, #define our file magic here.
693 2000-06-23 Havoc Pennington <hp@redhat.com>
695 * make-inline-pixbuf.c: Small program that creates C variable
696 declarations of inline pixbuf data. This can be read
697 by gdk_pixbuf_new_from_inline.
699 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
700 inline pixbuf data and create a pixbuf from it.
702 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
704 2000-09-07 Tor Lillqvist <tml@iki.fi>
706 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
709 2000-08-12 Tor Lillqvist <tml@iki.fi>
711 * gdk_pixbuf.def: Add missing entry point.
713 2000-08-10 Havoc Pennington <hp@redhat.com>
715 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
716 (s/pixbuf_/pixbufloader_)
718 2000-08-02 Tor Lillqvist <tml@iki.fi>
724 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
726 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
727 one. Fix names of DLLs to have '-' instead of '_'.
729 2000-07-31 Elliot Lee <sopwith@redhat.com>
730 * io-wbmp.c: Some bug fixes - now tested to work.
732 2000-07-27 Elliot Lee <sopwith@redhat.com>
734 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
735 gdk_pixbuf_get_named_module() function to facilitate above change
736 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
737 Implement loader for WBMP format.
738 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
740 2000-07-23 Tor Lillqvist <tml@iki.fi>
745 * pixops/makefile.mingw.in
746 * pixbuf_*.def: New files.
749 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
751 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
752 New function, to get the GTK+ installation directory from
753 the Windows Registry, where the installation program
754 for whatever software includes GTK+ has stored it.
756 Used to avoid having hardcoding the directory where to look for
757 loaders. This function is needed by gtk, too, so it should
758 really be just in one place. Maybe a small static library
759 one level up from here?
761 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
762 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
763 Open file in binary mode. This *is* standard C. (No-op on Unix,
766 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
768 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
770 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
772 * pixops/*.S: The Gas from mingw32 doesn't like the .type
773 pseudo-op. Conditionalise on __MINGW32__, but probably
774 should conditionalise on Gas version instead? Or could we
775 do without .type on all systems?
777 * pixops/timescale.c: Use g_get_current_time()
778 instead of gettimeofday().
780 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
782 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
784 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
786 * gdk-pixbuf.c: Add <string.h> include.
788 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
790 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
791 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
792 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
793 use g_object_new() instead of g_type_create_instance() which
794 is a private function for fundamental type implementations.
796 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
798 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
799 soname scheme for gdk-pixbuf.
801 2000-06-21 Havoc Pennington <hp@pobox.com>
803 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
804 (i.e. derivation is not allowed, and there are no virtual methods
806 (gdk_pixbuf_preinit): Call g_type_init() here.
807 (gdk_pixbuf_init): Add a user-friendly init function, for users
808 of standalone gdk-pixbuf
810 * gdk-pixbuf-animation.c: Convert to GObject, in the same
811 way GdkPixbufAnimation was done.
813 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
814 gdk_pixbuf_finalize() from API, since these are broken and don't
815 make sense with new GObject stuff.
817 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
819 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
820 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
823 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
825 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
826 so I needed something to warm my thighs. Running plain infinite
827 loops on your laptop to make it hot is not very much fun. A demo
828 of the gdk-pixbuf scaling functions is way better, and looks
831 * configure.in (AC_OUTPUT): Added the demo Makefile.
833 * Makefile.am (SUBDIRS): Added the demo directory.
835 2000-06-09 Larry Ewing <lewing@helixcode.com>
837 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
838 setjmp for the png error handler. It seems setting the error
839 handling functions does not avoid the jump, and so not calling
840 setjmp was causing the incremental loader to jump into lala land.
841 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
842 not sure this one is actually required but the docs say it must be
843 set for every call to a png_* function.
844 Also changed the comment to reflect the fact that setting the
845 error handlers does _not_ avoid the longjmp.
847 2000-06-06 Larry Ewing <lewing@helixcode.com>
849 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
850 take frame offest into account when trying to calculate the
851 animation bbox. Also set the width to the width not the height.
852 (gdk_pixbuf_loader_animation_done): cycle over the frames to
853 calculate bbox because now we finally have all the offset
854 information for each frame.
856 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
858 * configure.in: add some gtk parameters to the
859 GDK_PIXBUF_LIB²S and GDK_PIXBUG_INCLUDEDIR vars. One more
860 fight in my crusade for strange prefix compile...
862 2000-05-30 Not Zed <NotZed@HelixCode.com>
864 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
865 Initialise the error handler exit routine to our own. Note this
866 means that every function that accesses the jpeg lib on this
867 object MUST do a setjmp.
868 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
869 lib for handling fatal error.
870 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
871 your applications dont quit if there's a jpeg error!
873 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
875 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
876 from Frank de Lange <frank@unternet.org>.
878 2000-05-09 Darin Adler <darin@eazel.com>
880 * gdk-pixbuf/test-gdk-pixbuf.c:
881 Fixed includes to get rid of accidental GNOME dependency.
883 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
884 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
886 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
888 * configure.in: Bumped version number to 0.8.0.
890 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
891 file was not being distributed.
893 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
895 2000-05-09 Darin Adler <darin@eazel.com>
897 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
898 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
899 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
900 formats to 32-bit formats to re-use the high bits of the color values
901 so that white maps to full white.
903 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
905 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
906 detailed information about the structure and algorithms
907 of pixops so people can fix it instead of breaking it.
909 2000-05-04 Darin Adler <darin@eazel.com>
911 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
912 (composite_pixel), (composite_line):
913 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
914 Now that Owen explained the algorithm, I think I implemented it
915 right for the cases where the destination pixbuf is not opaque.
916 The test does seem to confirm it.
918 2000-05-04 Darin Adler <darin@eazel.com>
920 * gdk-pixbuf/.cvsignore:
921 * gdk-pixbuf/Makefile.am:
922 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
923 (load_pixel), (simple_composite_test_one),
924 (simple_composite_test_one_type), (simple_composite_test), (main):
925 Added some tests of composite to highlight problems in the old
926 implementation. These tests run without any user interaction.
927 Just do "make check".
929 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
930 (composite_pixel), (composite_line): Fix composite to do a textbook
931 "A over B" composite. This was clearly the intent, and it was easy
932 to fix the code to do it. (Note to those that read my earlier tries
933 at a patch; this version fixes typos that were present in all
934 my patch attempts. I checked the final version by adding more tests.)
936 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
938 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
939 offset y coordinate accordining to render_y0.
941 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
944 2000-04-22 James Henstridge <james@daa.com.au>
946 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
947 package to the devel package. The only file installed in bin is
948 gdk-pixbuf-config, which belongs in -devel. This should allow having
949 multiple versions of the main gdk-pixbuf package installed.
951 2000-04-17 Karl Eichwalder <ke@suse.de>
953 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
954 Reported by Jens Finke.
956 2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
958 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
959 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
961 2000-04-13 James Henstridge <james@daa.com.au>
963 * configure.in: when performing the configure check to see if
964 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
965 rather than the other way round. Also, call AC_MSG_RESULT in the
966 even that dynamic modules were not supported.
968 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
970 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
971 hook to the last unref operation.
973 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
974 function to set the last unref handler for a pixbuf.
975 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
976 It calls the pixbuf's destroy notification function and frees the
977 GdkPixbuf structure itself.
978 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
981 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
982 for the last unref handler and its user data.
984 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
985 g_new0() to allocate the pixbuf.
987 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
988 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
989 was not specifying the `frame' argument.
991 * gdk-pixbuf/gdk-pixbuf-animation.c
992 (gdk_pixbuf_animation_get_width): Fixed docstring.
993 (gdk_pixbuf_animation_get_height): Likewise.
994 (gdk_pixbuf_animation_get_num_frames): Likewise.
995 (gdk_pixbuf_animation_get_frames): Likewise.
997 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1000 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1002 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1004 * doc/tmpl/refcounting.sgml: Updated with the information about
1005 the last unref handler.
1007 * doc/tmpl/*.sgml: Markup tweaks.
1009 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1010 update the libtool version number for libgnomecanvaspixbuf as
1012 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
1013 as well, or the old ones won't work with the new stuff. Also,
1014 renamed the modules as follows.
1016 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
1017 modules are called "libpixbufloader-<format>.so" instead of
1018 "libpixbuf-<format>.so". They needed renaming so that the new
1019 loaders won't overwrite the old ones; even with the versioning
1020 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
1023 2000-04-12 Paolo Molaro <lupus@debian.org>
1025 * .cvsignore, src/.cvsignore: shut up cvs.
1027 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
1029 Most of this patch is based on a patch by Havoc Pennington
1030 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
1031 remove the libart dependency.
1033 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
1034 (GdkColorspace): New enum that for now only contains
1036 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
1037 notification function.
1038 (GdkInterpType): New num with interpolation types.
1040 * *.[ch]: Replace the libart stuff with our own stuff.
1042 * pixops/*.[ch]: Likewise.
1044 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
1045 declarations of the GdkPixbuf structures.
1047 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
1049 (gdk_pixbuf_get_format): Constify.
1050 (gdk_pixbuf_get_n_channels): Constify.
1051 (gdk_pixbuf_get_has_alpha): Constify.
1052 (gdk_pixbuf_get_bits_per_sample): Constify.
1053 (gdk_pixbuf_get_pixels): Constify.
1054 (gdk_pixbuf_get_width): Constify.
1055 (gdk_pixbuf_get_height): Constify.
1056 (gdk_pixbuf_get_rowstride): Constify.
1058 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
1061 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
1062 bits_per_sample argument; currently only 8 bits per sample are
1065 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
1067 (gdk_pixbuf_frame_get_x_offset): New accessor.
1068 (gdk_pixbuf_frame_get_y_offset): New accessor.
1069 (gdk_pixbuf_frame_get_delay_time): New accessor.
1070 (gdk_pixbuf_frame_get_action): New accessor.
1072 * gdk-pixbuf/gdk-pixbuf-render.c
1073 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
1074 mask rectangle for pixbufs without an alpha channel, set the
1075 *mask_return to NULL.
1077 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
1079 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
1081 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
1082 preconditions. Maybe we should also check for the colorspace,
1083 bits per pixel, and such.
1084 (gdk_pixbuf_composite): Likewise.
1085 (gdk_pixbuf_composite_color): Likewise.
1086 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
1087 cannot allocate the new pixbuf.
1088 (gdk_pixbuf_composite_color_simple): Likewise.
1090 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
1091 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
1094 * gdk-pixbuf/io-bmp.c: Fix includes.
1096 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
1101 * configure.in: Removed checks for libart.
1103 * gdk-pixbuf/Makefile.am: Removed references to libart.
1104 (noinst_HEADERS): Added gdk-pixbuf-private.h.
1106 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
1107 the version number of the libtool library to indicate that this
1108 definitely is not compatible with the old usage. I know you love
1111 * configure.in: Bumped version number to 0.7.0.
1115 * gdk-pixbuf-config.in (--libs): We no longer require libart.
1117 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.

1630 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
1631 with a reference count of 1.
1633 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
1634 gdk-pixbuf-animation.c.
1636 * doc/tmpl/animation.sgml: Populated. It is still missing a
1637 description of the overlay modes.
1639 * doc/gdk-pixbuf-sections.txt: Added the animation section. Moved
1640 the canvas item section to the end, as it will be moved later to
1643 * doc/gdk-pixbuf.sgml: Added the animation section.
1645 * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
1647 1999-12-26 Peter Teichman <pat@gnu.org>
1649 * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add
1650 $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker.
1651 This closes bug #4676.
1653 1999-12-23 Havoc Pennington <hp@pobox.com>
1655 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
1656 set to NULL here (specifically context->animation) was not being
1657 set to NULL. use g_new0() to alloc the struct.
1659 1999-12-20 Jonathan Blandford <jrb@redhat.com>
1661 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
1662 correctly. Progressive loading needs some work, but that all
1663 needs doing from the gdk-pixbuf-loader end, not here.
1665 1999-12-17 Jonathan Blandford <jrb@redhat.com>
1667 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
1668 moved the file here. It seems natural to put this function here,
1669 as that's where the gdk_pixbuf_new_from_file function is, but it's
1670 still a little convoluted. The source files might be played with
1673 1999-12-14 Jonathan Blandford <jrb@redhat.com>
1675 * gdk-pixbuf/gdk-pixbuf-loader.c
1676 (gdk_pixbuf_loader_get_animation): Gets the animation from the
1679 1999-12-16 Federico Mena Quintero <federico@redhat.com>
1681 * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
1682 before using the GdkPixbuf rendering functions. Thanks to Joe
1683 Shaw <joe@off.net> for pointing this out.
1685 1999-12-13 Federico Mena Quintero <federico@redhat.com>
1687 * gdk-pixbuf/gnome-canvas-pixbuf.c
1688 (gnome_canvas_pixbuf_class_init): Renamed arguments to
1689 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
1690 consistency with the new canvas.
1691 (PixbufPrivate): Do the same renaming in the structure fields, for
1694 * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.
1696 1999-12-12 Federico Mena Quintero <federico@redhat.com>
1698 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
1699 conditional to see whether to link $(GNOME_LIBS) or not.
1701 1999-12-10 Jonathan Blandford <jrb@redhat.com>
1703 * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API.
1705 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
1706 make a warning go away.
1708 * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations.
1710 * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for
1713 1999-12-09 Michael Zucchi <zucchi@zedzone.mmc.com.au>
1715 * gdk-pixbuf/gdk-pixbuf.h: Enable gdk_pixbuf_get_from_drawable()
1718 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
1719 Filled in body of function.
1720 (rgbconvert): Added GdkColormap parameter, and to all conversion
1722 (convert_real_slow): New function - should convert ANY visual/data
1723 format properly, but it aint fast. Used as a fallback when an
1724 optimised routine wont match.
1725 (rgbconvert): Do very specific tests on the data format to verify
1726 properly if the optimised version will do, otherwise use the
1727 fallback function for all other data formats.
1729 * gdk-pixbuf/Makefile.am: Re-enabled building of
1730 textpixbuf-drawable.
1732 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
1733 gdk_pixbuf_get_from_drawable().
1735 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
1737 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
1738 bug on two occasions.
1739 * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu
1740 function to the generic glib one.
1742 1999-12-08 Federico Mena Quintero <federico@redhat.com>
1744 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
1745 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
1746 checks and API definition. The body needs filling in and it needs
1747 to do the Right Thing(tm) for pixmaps plus the given colormap and
1748 windows and their own colormaps.
1750 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
1751 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
1753 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
1755 * doc/tmpl/from-drawables.sgml: Populated.
1757 * doc/gdk-pixbuf.sgml: Added the from-drawables section.
1759 * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml.
1761 * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs
1764 1999-12-07 Federico Mena Quintero <federico@redhat.com>
1766 * doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about
1767 reference counting for GdkPixbuf structures.
1769 1999-12-07 Martin Baulig <martin@home-of-linux.org>
1771 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
1772 include $(GNOME_LIBS) here.
1774 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
1776 Added missing "include <string.h>" to:
1777 * gdk-pixbuf/io-ras.c
1778 * gdk-pixbuf/io-bmp.c
1779 * gdk-pixbuf/io-ico.c
1781 1999-12-06 Federico Mena Quintero <federico@redhat.com>
1783 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
1786 1999-12-05 Federico Mena Quintero <federico@redhat.com>
1788 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
1789 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
1790 want, send me a patch to do the conditional stuff properly.
1791 Otherwise, please read the GNOME Programming Guidelines,
1792 especially the "CVS policies" section.
1794 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
1796 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
1798 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
1800 * gdk-pixbuf/io-ico.c: Bug in palet-size
1803 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
1805 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
1806 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
1808 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
1810 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
1813 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
1814 (Windows Cursor files). These are identical to .ICO files,
1815 except for the signature and 2 extra fields for the hotspot.
1817 1999-12-03 Federico Mena Quintero <federico@redhat.com>
1819 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):
1820 Removed unused variable `item'.
1822 1999-12-03 Jonathan Blandford <jrb@redhat.com>
1824 * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
1825 explain this function better.
1827 1999-12-02 Federico Mena Quintero <federico@redhat.com>
1829 Source files moved from src/ to gdk-pixbuf/, to be consistent with
1832 * doc/Makefile.am: Modified for the new source directory.
1834 * configure.in: Likewise.
1836 * Makefile.am: Likewise.
1838 * autogen.sh: Likewise.
1840 * gdk-pixbuf/Makefile.am: Likewise.
1842 1999-12-02 Federico Mena Quintero <federico@redhat.com>
1844 * src/testpixbuf.c: #include <config.h>, and fix includes.

1870 * src/gdk-pixbuf-render.c: Fix includes.
1872 * src/gdk-pixbuf-io.h: Fix includes.
1874 * src/gdk-pixbuf-drawable.c: Fix includes.
1876 * src/gdk-pixbuf-drawable.h: Use angle brackets for the gdk-pixbuf
1879 * src/gdk-pixbuf-data.c: Fix includes.
1881 * src/gdk-pixbuf-loader.c: #include <config.h>
1883 * src/gdk-pixbuf-loader.h: Use angle brackets for the gdk-pixbuf

1891 * src/gdk-pixbuf-util.c: New file with utility and convenience
1892 functions for pixbufs.
1894 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c.

1902 * doc/tmpl/util.sgml: Documentation for the utility functions.
1904 1999-11-29 Owen Taylor <otaylor@redhat.com>
1906 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
1907 Keep the mask around until after we draw ... since
1908 the GC changes aren't flushed to the X server until we
1909 draw, destroying it before that may result in BadPixmap
1912 1999-11-30 Havoc Pennington <hp@pobox.com>
1914 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
1916 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
1918 1999-11-29 Federico Mena Quintero <federico@redhat.com>
1920 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
1921 should be made conditional, not blindly commented out.
1923 1999-11-29 Jonathan Blandford <jrb@redhat.com>
1925 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
1926 handle .ico files. Cool.
1928 1999-11-24 Jonathan Blandford <jrb@redhat.com>
1930 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
1933 1999-11-24 James Henstridge <james@daa.com.au>
1935 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
1936 top builddir rather than src. This still builds fine, and does not
1937 get gtk-doc into an infinite loop when trying to find all the source
1940 1999-11-23 Jonathan Blandford <jrb@redhat.com>
1942 * Removed #PRAGMA } from headers. Also, make compile if you don't
1943 have it installed, already.
1945 1999-11-22 Federico Mena Quintero <federico@redhat.com>
1947 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
1948 temporary buffer to the size of the interesction of the bounding
1949 box and the expose area, not the whole expose area. This speeds
1952 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
1953 not paint black on the mask, since we already cleared it in a
1954 single gdk_draw_rectangle() operation.
1956 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
1958 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
1960 1999-11-22 Havoc Pennington <hp@pobox.com>
1962 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
1963 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
1964 dependencies to LIBADD variables for loadable modules. Necessary
1965 for a Java dynamic loading thing to be able to figure it out.
1967 1999-11-22 Havoc Pennington <hp@pobox.com>
1969 * src/io-png.c (image_load_increment): Call the update_area
1970 callback depending on the number of rows loaded in this increment.
1972 * src/testpixbuf.c (main): slow down the progressive load demo
1974 1999-11-16 Havoc Pennington <hp@pobox.com>
1976 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
1978 1999-11-22 Jonathan Blandford <jrb@redhat.com>
1980 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
1981 for srcdir != buildir != . Beats me why; I can't figure it out.
1982 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
1984 1999-11-21 Jonathan Blandford <jrb@redhat.com>
1986 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
1987 <arjan@fenrus.demon.nl>
1989 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
1991 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
1992 Rework/reorder of the code. Each case has been separated into
1993 another function; its big but it should be quick.
1994 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
1995 opaque alpha information. Not all depths/formats have been
1996 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
1998 1999-11-17 Larry Ewing <lewing@gimp.org>
2000 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2001 implement the bounds method correctly.
2002 (compute_viewport_affine): compute the affine need to fit the
2003 image within the viewport given by the args.
2004 (compute_render_affine): call compute_viewport_affine.
2006 1999-11-16 Havoc Pennington <hp@pobox.com>
2008 * src/gdk-pixbuf-drawable.h: Use includes from the current
2009 directory, not the system directory.
2011 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
2013 * src/testpixbuf-drawable.c: use includes from the current directory
2014 rather then from the system include directory as gdk-pixbuf
2015 includes are not yet installed when this is compiled.
2017 1999-11-13 Cody Russell <bratsche@dfw.net>
2018 * src/testpixbuf-drawable.c: Added a test program for drawable
2021 * src/Makefile.am: Build testpixbuf-drawable.
2023 1999-11-12 Cody Russell <bratsche@dfw.net>
2025 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.
2027 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2029 * doc/tmpl/gdk-pixbuf-loader.sgml: Populated.
2031 * doc/gdk-pixbuf.signals: Put in the real names of signal
2034 * src/gdk-pixbuf-loader.c: Improved documentation comments.
2036 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2038 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
2041 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
2042 correctly. Patch from Arjan to do so.
2044 1999-11-10 Michael Fulbright <drmike@redhat.com>
2046 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
2049 * src/testpixbuf.c: Added final queued draw when done loading image.
2051 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2053 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
2056 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2058 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
2061 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2063 * src/io-png.c: Fixed some incompatible pointer initializations.
2065 * src/io-jpeg.c (image_load_increment): Remove unused variable.
2067 1999-11-09 Michael Fulbright <drmike@redhat.com>
2069 * src/testpixbuf.c: Fixed it to use timeout to read from file
2070 for progressive loading. Set TBF_KBPS=n, where n is the number of
2071 kilobytes/second to simulate in downloading. n has to be an integer.
2073 * src/io-jpeg.c: Slight cosmetic cleanup.
2075 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
2076 PBM loading has a similar problem and will address tomorrow.
2078 1999-11-09 Havoc Pennington <hp@pobox.com>
2080 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
2081 gdk-pixbuf-drawable stuff.
2083 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2085 * configure.in: Bumped version number to 0.4.
2087 1999-11-09 Michael Fulbright <drmike@redhat.com>
2089 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
2090 all types of PNM files now.
2092 * src/io-jpeg.c (image_load_increment): Figured out problem with
2093 loading Progressive JPEG's progressively (say that 10 times fast).
2094 Currently for Progressive JPEG's the entire image is loaded before
2095 it is displayed. libjpeg supports a fancier mechanism which I may
2098 With these changes all JPEG formats appear to load properly for me.
2100 1999-11-08 Jonathan Blandford <jrb@redhat.com>
2102 * src/io-ras.c (image_load_increment): Final patch from Arjan.
2103 Seems to do progressive loading.
2105 1999-11-08 Michael Fulbright <drmike@redhat.com>
2107 * src/io-pnm.c image_load (): Fixed so we do not create a separate
2108 pixel buffer when reading in image - we reuse the pixel data in
2109 the GdkPixbuf structure instead.
2111 1999-11-08 Michael Fulbright <drmike@redhat.com>
2113 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
2114 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
2115 I can't seem to find a utility to convert into this format.
2116 Next is to add progressive loading support for the PNM format.
2118 1999-11-07 Federico Mena Quintero <federico@redhat.com>
2120 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
2121 of the width, height, x, and y setting and pixels arguments.
2123 1999-11-05 Jonathan Blandford <jrb@redhat.com>
2125 * src/io-ras.c (image_load): third patch. Now it seems to load.
2127 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
2128 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
2130 * src/io-ras.c (image_load): new file from Arjan van de Ven
2131 <arjan@fenrus.demon.nl> to begin the ras loader.
2133 1999-11-05 Federico Mena Quintero <federico@redhat.com>
2135 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
2136 for internal use only.
2138 * doc/gdk-pixbuf.sgml: Likewise.
2140 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
2142 1999-11-05 Michael Fulbright <drmike@redhat.com>
2144 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
2145 files from a file. Next step is support for ASCII files, and
2146 then incremental loading.
2148 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2150 * Makefile.am: Added doc to SUBDIRS.
2152 1999-11-04 Michael Fulbright <drmike@redhat.com>
2154 * src/io-jpeg.c: Prettied up code slightly.
2155 * src/io-pnm.c: Start of pnm loader (from file and progressively).
2156 Doesn't do much yet (will finish tomorrow).
2157 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
2159 1999-11-04 Federico Mena Quintero <federico@redhat.com>
2161 * doc/tmpl/rendering.sgml: Populated.
2163 * doc/Makefile.am: Added the template files.
2165 1999-11-04 Havoc Pennington <hp@pobox.com>
2167 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
2168 docs, explain what a dither offset is for.
2169 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
2170 this function vs. gdk_pixbuf_render_to_drawable().
2172 1999-11-04 Havoc Pennington <hp@pobox.com>
2174 * configure.in: Use libart-config correctly; find gnome-config
2175 separately. Fix GNOME_LIBS to be correct in "no gnome installed
2178 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
2181 Patch untested in the inside-gnome-libs case, I need to commit
2182 then check out to the gnome-libs I'm using.
2184 1999-11-04 Michael Fulbright <drmike@redhat.com>
2186 * src/io-jpeg.c (image_begin_load): Add update_func callback.
2187 * src/io-jpeg.c (image_load_increment): Call updated callback when
2188 new graphic data decoded.
2190 1999-11-04 Jonathan Blandford <jrb@redhat.com>

2220 * src/Makefile.am: Unconditionally build the GIF loader.
2222 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2224 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
2225 Added a lot of comments to the file.
2227 * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
2230 1999-11-03 Michael Fulbright <drmike@redhat.com>
2232 * src/io-jpeg.c (image_load_increment): Further removal of
2233 bugginess in local buffering code. Handles grayscale jpegs
2236 * src/io-jpeg.c (image_load_stop): Was freeing local context
2237 for jpeg library before calling jpeg_decompres_finish ().
2239 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2241 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
2243 (gif_get_lzw): set the transparency to the right val.
2245 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2247 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
2248 Initiailize the x and y fields.
2249 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
2250 (PixbufPrivate): Renamed need_size_update to need_xform_update.
2251 (recompute_bounding_box): Do not use temporary values.
2253 1999-11-03 Jonathan Blandford <jrb@redhat.com>

2261 1999-11-03 Larry Ewing <lewing@gimp.org>
2263 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
2264 render_affine calculation for x,y offsets.
2265 (gnome_canvas_pixbuf_set_arg): add x,y args.
2266 (gnome_canvas_pixbuf_get_arg): add x,y args.
2267 (recompute_bounding_box): simply code using ArtDrect and the
2268 render_affine. Removed compute_xform_vectors as it was no longer
2271 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2273 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
2274 doofus. Return a distance, not a boolean, for opaque images.
2276 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
2277 rounding of bounding box coordinates.
2278 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
2279 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
2281 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2283 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
2285 1999-11-03 Michael Fulbright <drmike@redhat.com>
2287 * src/io-jpg.c (image_load_increment): Fixed code which moved
2288 buffer around as new data comes in to work properly. JPEG progressive
2289 loading should be working now except for grayscale JPEG's, which I
2290 will look into next.
2292 1999-11-03 <sopwith@redhat.com>
2293 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
2294 Also put dot printing back in.
2296 1999-11-03 <jrb@redhat.com>
2298 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
2301 1999-11-02 Cody Russell <bratsche@dfw.net>
2302 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
2303 if part of the requested image is offscreen, rather than clipping
2306 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2308 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
2309 for interlacing and progressive loading.
2311 1999-11-02 Cody Russell <bratsche@dfw.net>
2312 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
2313 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
2315 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2317 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
2318 It's a little slow though. )-:
2320 1999-11-02 Elliot Lee <sopwith@redhat.com>
2321 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
2322 write/load_increment operations const-correct.
2324 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2326 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
2327 Implemented the ::point() method. We do a simple containment test
2328 instead of a full distance calculation since the canvas is going
2329 to change to that scheme, anyways.
2331 1999-11-02 Elliot Lee <sopwith@redhat.com>
2333 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
2334 that are read from the input file.
2336 1999-11-02 Larry Ewing <lewing@gimp.org>
2338 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
2340 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
2343 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2345 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
2346 affine computation code from ::draw() to here, since it is needed
2347 by ::point() as well.
2349 1999-11-02 Elliot Lee <sopwith@redhat.com>
2351 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
2352 three functions, and eliminate duplication of code from write()
2353 and close(). Also fix bug where the 128-byte header was being
2356 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2357 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
2358 bounding box computation.
2360 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2362 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
2363 Drawing affines seem to work. Bounding box is fubared. ::point()
2364 is not implemented. This is a work in progress.
2366 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
2369 * configure.in: Sigh. We need to link in libgnomeui for the
2370 canvas stuff. This mess will disappear when gdk-pixbuf gets
2371 folded into gnome-libs.
2373 1999-10-30 Jonathan Blandford <jrb@redhat.com>
2375 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
2376 the right size, at a minimum, even if the image is squished and
2378 (ReadImage): lets get the offset right. This will let transparent
2381 1999-10-29 Michael Fulbright <drmike@redhat.com>
2383 * src/io-jpeg.c: image_load_increment(): Fixed bug when
2384 image width was not a multiple of 4 - always use the
2385 gdk_pixbuf rowstride to increment pointers!
2387 1999-10-29 Michael Fulbright <drmike@redhat.com>
2389 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
2390 Currently does not handle either progressive jpeg files (jpeg
2391 files with multiple scans at different quality settings), but
2392 I plan on adding this support soon. These are fairly rare in
2393 my experience, so it shouldn't slow people down too much.
2394 Grayscale jpegs also don't work but that should be easy to fix.
2396 1999-10-29 Michael Fulbright <drmike@redhat.com>
2398 * src/testpixbuf.c: Added title to windows so you can identify
2399 progressive and file windows.
2401 1999-10-29 Michael Fulbright <drmike@redhat.com>
2403 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
2404 load the image handler when we determine the image type.
2406 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
2407 previously static function load_image_handler () to
2408 a public function gdk_pixbuf_load_module (). It is needed in
2409 gdk-pixbuf-loader.c to load image handler modules. This function
2410 is different from gdk_pixbuf_get_module (), which only returns
2411 a reference to the required handler, because it actually loads
2412 the handler into memory. Both actions should possibly be combined
2413 in a convenience function since one w/o the other doesn't seem to
2416 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2418 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
2421 1999-10-28 Federico Mena Quintero <federico@redhat.com>
2423 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
2424 function to render a portion of a pixbuf to a drawable. Ignores
2425 alpha information and takes in a GC.
2426 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
2427 portion of a pixbuf to a drawable. It automatically creates a GC
2428 and a clipping mask for alpha pixbufs.
2430 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2432 * src/gdk-pixbuf.h: turned convenience macros into convenience
2433 functions so some error checking could be added.
2435 * src/io-tiff.c (image_load_increment): started work on the tiff
2436 non-incremental loader.
2437 (image_begin_load): Finished the incremental loader.
2439 * src/io-gif.c (image_load_increment): started work on the gif
2442 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
2444 1999-10-27 Federico Mena Quintero <federico@redhat.com>
2446 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
2447 function to threshold a pixbuf's alpha channel into a bitmap.
2449 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
2450 contemplate future extensions to ArtPixBuf's formats.
2452 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
2454 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
2455 macros to fetch the ArtPixBuf's fields.
2457 1999-10-27 Havoc Pennington <hp@pobox.com>
2459 * src/testpixbuf.c (main): Display the progressive load
2461 * src/io-png.c (setup_png_transformations): Break transformation
2462 code into separate function
2463 (png_info_callback): Use setup_png_transformations
2465 1999-10-27 Havoc Pennington <hp@pobox.com>
2467 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
2468 properly whether the XPM module has already been loaded
2469 (gdk_pixbuf_new_from_file): Check properly if loader module
2470 was already loaded (was checking if load symbol was present
2471 in order to decide whether to re-load; should check module !=
2472 NULL, then load != NULL)
2473 (image_handler_load): Check in present working directory,
2474 makes it easier to debug for now
2475 (file_formats): This array initializer was seriously on crack,
2476 was assigning a function pointer to a GModule*
2478 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
2480 1999-10-27 Havoc Pennington <hp@pobox.com>

2488 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
2489 GdkPixbufLoader, not a GtkObject.
2490 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
2491 (gdk_pixbuf_loader_get_type): Documented.
2492 (gdk_pixbuf_loader_class_init): Initialize the parent class
2494 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
2495 class destroy function.
2496 (gdk_pixbuf_loader_new): Documented.
2497 (gdk_pixbuf_loader_finalize): Call the parent class finalize
2499 (gdk_pixbuf_loader_write): Use size_t for count.
2501 1999-10-27 Michael Fulbright <drmike@redhat.com>
2503 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
2504 logic so we only try to close loader if it wasn't previously closed.
2506 1999-10-27 Michael Fulbright <drmike@redhat.com>
2508 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of

2535 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
2537 1999-10-22 Havoc Pennington <hp@pobox.com>
2539 * src/io-xpm.c (mem_buffer): Clean up stupid
2540 increment-inside-array-dereference thing
2542 * src/testpixbuf.c: Add XPM data tests.
2544 * src/io-xpm.c: Make the XPM data buffer const, fix const
2545 correctness throughout the code.
2547 1999-10-22 Havoc Pennington <hp@pobox.com>
2549 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

2557 function, loads pixbuf from xpm data
2558 (image_handler_load): Add g_return_if_fail() to ensure the same
2559 module isn't loaded twice. Add g_module_symbol() to scan for XPM
2562 1999-10-22 Federico Mena Quintero <federico@redhat.com>
2564 * src/io-png.c (image_load): Patch from Kristian Hogsberg
2565 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
2566 buffers; the rows can be read in directly into the main pixel
2569 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2571 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
2573 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2575 * configure.in: Bumped version number to 0.3.
2577 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
2578 version number for the library.
2580 1999-10-20 Federico Mena Quintero <federico@redhat.com>

2586 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
2588 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
2589 terms of the libart functions. Removed the old code.
2591 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
2592 symbols. Saving will not be implemented in GdkPixbuf.
2594 * src/io-gif.c: Removed the saving stub.
2595 (image_load): Fixed memory management to fail gracefully if we run
2596 out of memory while loading the image. Close the gif file when we
2597 are done. This still needs more error handling for the DGif
2600 * src/io-jpeg.c (image_load): Some robustness fixes.
2602 * src/io-png.c: Removed the saving stuff.
2603 (image_load): Some memory management fixes.

2615 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2617 * src/*: Reindented to use the GNOME Indentation. Renamed
2618 GdkPixBuf to GdkPixbuf, for consistency with the function names
2619 (and it is also easier to type) :-)
2621 1999-10-18 Havoc Pennington <hp@pobox.com>
2623 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
2625 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
2627 1999-10-18 Havoc Pennington <hp@pobox.com>
2629 * Makefile.am (SUBDIRS): Remove "macros"
2631 * configure.in: Don't use GNOME_INIT, handle case where we are
2632 inside gnome-libs. AM_PATH_GTK for the GIF test

2635 comment out testpixbuf for now
2637 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2639 * configure.in: Use $GTK_LIBS as the extra libs when checking for
2640 libgif/libungif, as they need the X libraries. Fixes bug #2472.
2642 1999-10-10 Cody Russell <bratsche@dfw.net>
2643 * src/gdk-pixbuf-drawable.c: core function now determines whether
2644 the requested geometry is on screen or not, and if some is not
2645 then the request is clamped to geometry that is on the screen.
2647 Changed 'pixbuf' to 'art_pixbuf' in core function.
2649 1999-10-08 Michael Fulbright <drmike@redhat.com>
2651 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

2654 if no filename given to test program.
2656 1999-10-07 Cody Russell <bratsche@dfw.net>
2657 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
2658 them, but I wrote them).
2660 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
2663 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
2664 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

2678 GdkPixBufUnrefFunc + gdk_pixbuf_new.
2680 * src/io-jpeg.c (image_load): clean to use gdk_pixbuf_new.
2682 * src/io-xpm.c (_pixbuf_create_from_xpm): ditto.
2684 * src/io-tiff.c (image_load): ditto + fix leak
2686 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
2687 crashes this module ( add warning :-)
2689 * src/io-bmp.c (image_load): ditto.
2691 * src/io-gif.c (image_load): ditto.
2693 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
2695 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
2696 it doesn't crash scaling with alpha.
2698 1999-09-17 Federico Mena Quintero <federico@redhat.com>
2700 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
2702 * src/io-gif.c (image_load): Likewise.
2704 * src/io-jpeg.c (image_load): Likewise.
2706 * src/io-png.c (image_load): Likewise.
2708 * src/io-tiff.c (image_load): Likewise.
2710 * src/io-xpm.c (_pixbuf_create_from_xpm): Likewise.
2712 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_image): Added an assertion

2723 into account the ArtPixbuf's rowstride when assigning the row
2726 * src/gdk-pixbuf.c: Fixup includes.
2728 * src/gdk-pixbuf-io.c: Likewise.

2735 1999-07-29 Mark Crichton <crichton@gimp.org>
2737 * src/io-png.c (image_save): Added PNG saving function
2739 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
2740 image_save(GdkPixBuf *p, FILE *f, ...)
2743 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
2745 * src/Makefile.am (*_LIB): Only build the relevant loaders which
2746 require extra libraries if we actually have those libraries.
2748 1999-07-23 Richard Hestilow <hestgray@ionet.net>
2750 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
2751 * gdk_pixbufConf.sh.in: Added for gnome-config
2753 * configure.in: Modified to generate gdk_pixbufConf.sh
2755 1999-07-20 Mark Crichton <crichton@gimp.org>
2757 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
2758 calculation needs to be done.
2760 1999-07-18 Larry Ewing <lewing@gimp.org>
2765 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
2766 error cases but one or two in the common case. There are probably
2767 a few small ones left.
2769 1999-07-18 Mark Crichton <crichton@gimp.org>
2771 * configure.in: removed version.h.
2773 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
2776 1999-07-17 Mark Crichton <crichton@gimp.org>
2778 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
2779 (gdk_pixbuf_rotate): Added pixbuf rotation code.
2780 (gdk_pixbuf_scale): Changed // comments to /* */
2782 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
2785 1999-07-16 Larry Ewing <lewing@gimp.org>
2787 * src/testpixbuf.c (expose_func): reverted the expose everything
2788 changes, I'm not sure why these went in.
2789 (config_func): bring this up to date with the new pixbuf_scale
2792 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
2793 loading code so that poeple can diagnose problems better.
2795 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
2796 no longer allocates a new pixbuf, which make things nicer for the
2797 rest of the code. Unfortunately there is still a problem with
2798 scaling rgba images.
2800 1999-07-16 Mark Crichton <crichton@gimp.org>
2802 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
2803 calls gdk_pixbuf_scale. However, something is not working.
2804 N.B.: current pixmap is now stored in user_data with a key of
2807 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
2808 Something is still borked, however.
2810 1999-07-15 Larry Ewing <lewing@gimp.org>
2812 * src/io-jpeg.c (image_load): add raph@gimp.org's fix to the jpeg
2815 * src/testpixbuf.c (main): fix up the file routines a little so
2816 that you can load multiple files given the file names
2818 1999-07-14 Larry Ewing <lewing@gimp.org>
2820 * src/testpixbuf.c (expose_func): added an almost proper expose
2821 handler for testpixbuf
2823 1999-07-13 Mark Crichton <crichton@gimp.org>
2825 * configure.in: Fixed GIF check. Replaced " with '
2826 * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale
2828 1999-07-13 Mark Crichton <crichton@gimp.org>
2830 * configure.in: I am a bonehead. Added gif-lib check.
