1 2001-10-02 Sven Neumann <sven@gimp.org>
3 * gdk-pixdata.c: g_string_printfa => g_string_append_printf.
5 Wed Sep 26 18:08:19 2001 Owen Taylor <otaylor@redhat.com>
7 * Makefile.am (s-enum-types-h): Fix a typo in the include
8 guards. (#61254, Skip Montaro)
10 2001-09-21 Matthias Clasen <matthiasc@poet.de>
12 * io-xpm.c (xpm_extract_color): Rewritten to handle
13 xpm colormap entries more thoroughly. (#59939)
15 2001-09-21 Hans Breuer <hans@breuer.org>
17 * gdk-pixbuf.def : updated externals
19 * makefile.msc : generate gdk-pixbuf-enum-types.[hc]
21 Thu Sep 20 17:22:48 2001 Owen Taylor <otaylor@redhat.com>
23 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
24 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't
25 work here since we are using the raw file descriptor. So, we call lseek()
26 on the fileno(f) before using it. (#60840).
28 2001-09-20 James Henstridge <james@daa.com.au>
30 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
31 so that flags types are registered as flags rather than enums (not
32 that there are any flags here at the moment).
34 Wed Sep 19 00:28:24 2001 Owen Taylor <otaylor@redhat.com>
36 * Makefile.am (gdk_pixbuf_headers): Don't include
37 gkd-pixbuf-features.h here since is in builddir
38 and confuses autogen rules.
40 * Makefile.am: Don't += variables before they have values,
41 automake-1.5 doesn't like it.
43 * Makefile.am: Fix srcdir != builddir for gdk-pixbuf-enum-types.c.
45 * Makefile.am: The whitespace strikes back.
47 2001-09-17 Matt Wilson <msw@redhat.com>
49 * Makefile.am (libpixbufloader_xbm_la_LDFLAGS): removed duplicate
50 LDFLAGS definition, use the -avoid-version one.
51 (libpixbufloader_tga_la_LDFLAGS): likewise
53 Mon Sep 17 11:49:02 2001 Owen Taylor <otaylor@redhat.com>
55 * pixops/*: Mirror GdkInterpType to PixopsInterpType
56 to avoid including gdk-pixbuf headers.
58 2001-09-16 James Henstridge <james@daa.com.au>
60 * .cvsignore: add generated files to ignore list.
62 * gdk-pixbuf.h: include gdk-pixbuf-enum-types.h
64 * Makefile.am: add rules to build gdk-pixbuf-enum-types.[ch]
66 Fri Sep 14 23:22:12 2001 Matthias Clasen <matthiasc@poet.de>
68 * io-pnm.c (pnm_read_header): Use GDK_PIXBUF_ERROR_CORRUPT_IMAGE,
69 not GDK_PIXBUF_ERROR_HEADER_CORRUPT. (#58308)
71 Fri Sep 14 22:53:45 2001 Matthias Clasen <matthiasc@poet.de>
73 * io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load): Handle
74 out-of-memory situation better.
76 * io-pnm.c: Robustness fixes for pnm loader
78 * io-gif.c: Make gif loader survive TEST_RANDOMLY_MODIFY
80 * io-xpm.c (parse_color): detect very long color strings
82 All of the above from Matthias Clasen <matthiasc@poet.de>,
83 the remaining from Soeren Sandmann <sandmann@daimi.au.dk>.
85 * test-images.h: add tests:
86 - four valid ppm's, eight invalid (matthiasc@poet.de)
87 - one invalid xpm (matthiasc@poet.de)
88 - one valid tga, one invalid (sandmann@daimi.au.dk)
89 - one invalid tiff (sandmann@daimi.au.dk
91 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
93 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
94 fail - detect it when it happens
96 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
99 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
102 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
104 * Makefile.am: don't used BUILT_SOURCES to build marshal
105 files, as in conjunction with stamp files, this can
106 lead to endless rebuilding loops.
108 Tue Sep 4 00:22:07 2001 Owen Taylor <otaylor@redhat.com>
110 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1
112 Tue Sep 4 03:09:52 2001 Tim Janik <timj@gtk.org>
114 * gdk-pixbuf-csource.1: new file, manual page for
115 the publically installed gdk-pixbuf-csource utility.
117 Thu Aug 30 08:30:03 2001 Matthias Clasen <matthiasc@poet.de>
119 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Propagate
120 errors from gdk_pixbuf_loader_load_module.
122 Thu Aug 30 08:27:37 2001 Matthias Clasen <matthiasc@poet.de>
124 * io-png.c (png_row_callback): Check that row_num is valid.
126 Tue Aug 28 21:05:26 2001 Matthias Clasen <matthiasc@poet.de>
128 * io-bmp.c (OneLine): Emit area_updated signal with proper
129 area information. (#52002)
131 Tue Aug 28 20:03:43 2001 Matthias Clasen <matthiasc@poet.de>
133 * test-loaders.c (test_loader): Catch errors at close time.
134 * test-loaders.c (main): Remove C++ comments.
136 2001-08-21 Matthias Clasen <matthiasc@poet.de>
138 * Makefile.am, gdk-pixbuf-io.c, pixbufloader_tga.def,
139 io-tga.c: Add tga loader, patch by Nicola Girardi. (#56067)
141 2001-08-20 Matthias Clasen <matthiasc@poet.de>
143 * test-images.h, test-loaders.c: Add ico and wbmp tests.
144 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): Fail with a suitable
145 error if buffer allocation fails.
146 * io-ico.c: Make .ICO loader more robust.
147 All of these are due to sandmann@daimi.au.dk (#50187)
149 2001-08-19 Sven Neumann <sven@gimp.org>
151 * pixops/pixops.c: applied some simple but effective optimizations
152 to pixops_composite_nearest() and pixops_composite_color_nearest().
154 2001-08-07 Sven Neumann <sven@gimp.org>
156 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
157 function, so that's what I did.
159 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
161 * gdk-pixdata.c: Fix a typo.
163 2001-07-30 Hans Breuer <hans@breuer.org>
165 * pixops/makefile.msc : new file
166 * makefile.msc : use it to complete the build
168 2001-07-20 Hans Breuer <hans@breuer.org>
170 * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
171 pointer increment out of the macro, because at least one
172 compiler (msvc 5.0) gets confused otherwise (applies the
175 * gdk_pixbuf.def : updated exports
177 * makefile.msc : reflect gdk-pixbuf-csource changes
179 2001-07-17 Darin Adler <darin@bentspoon.com>
181 * gdk-pixbuf-csource.c: Add missing <stdlib.h> include.
182 * io-png.c: (setup_png_transformations): Add ifdef so we compile
183 without warnings with G_DISABLE_CHECKS on.
184 * io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
186 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
187 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
188 unused locals and add an initial value to quiet the compiler's
189 unintialized variable warning.
190 * pixops/pixops.c: Put an ifdef around some dead code.
192 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
194 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
195 over to the new include flags AC_SUBST(). (Problem
196 pointed out by Mikael Hermansson.)
198 2001-06-29 Havoc Pennington <hp@redhat.com>
200 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): fix for
203 Thu Jun 28 21:54:19 2001 Owen Taylor <otaylor@redhat.com>
205 * make-inline-pixbuf.c test-gdk-pixbuf.c test-loaders.c
206 gdk-pixbuf-csource.c: Fix args to g_type_init ().
208 2001-06-28 Havoc Pennington <hp@pobox.com>
210 * gdk-pixdata.c: <string.h>
212 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
213 also leaking memory here from g_strdup_printf?)
215 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
217 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
219 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
220 instead from gdk_pixbuf_new_from_inline().
222 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
223 installed API for applications that need to serialize/deserialize
224 on their own (gimp, BEAST).
226 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
227 program that can dump images in CSource format and Pixbuf
228 stream format. supports RLE encoding, MACRO formatting etc...
231 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
233 * Makefile.am: Actually update timestamps, so rules don't
236 2001-06-11 Havoc Pennington <hp@redhat.com>
238 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
239 already includes top_builddir
241 2001-06-08 Havoc Pennington <hp@redhat.com>
243 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
244 bogus g_return_if_fail
246 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
247 likely timeout resolution, set it to an arbitrarily-chosen short
249 Fixes bug #55953 from warmenhoven@yahoo.com
251 2001-06-07 Havoc Pennington <hp@redhat.com>
253 * Makefile.am: use Owen's new way of doing stampfiles/generated
256 2001-06-07 Havoc Pennington <hp@redhat.com>
258 * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path
260 2001-06-05 Havoc Pennington <hp@redhat.com>
262 * test-loaders.c (main): use putenv not setenv, reported by
265 2001-05-08 Havoc Pennington <hp@redhat.com>
267 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
268 and fix behavior to still subst color if the original image
271 2001-06-04 Havoc Pennington <hp@redhat.com>
273 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
276 2001-06-01 Havoc Pennington <hp@redhat.com>
278 Apply patch from sandmann@daimi.au.dk, with some tweaks.
279 Makes things a bit more robust, and adds test-loaders.c
280 which is good for finding further robustness bugs to fix.
282 * io-tiff.c: Try to work around libtiff suckiness a bit;
283 put a giant thread lock on the whole loader,
284 paranoically check both whether error handlers were called and
285 also whether functions return false. Handle case where width or
286 height is 0. Various cleanups.
288 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
290 (png_error_callback): apparently libpng expects you to longjmp out
293 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
294 (lzw_read_byte): change "Mail jrb if this fails" g_warning
296 (gif_get_lzw): check for out-of-memory
297 (gif_prepare_lzw): catch/report an error
298 (new_context): use try_malloc, since GifContext is nearly 70K
299 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
300 so we don't crash later.
302 * Makefile.am: Add test-loaders
304 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
307 2001-05-29 Darin Adler <darin@eazel.com>
309 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
311 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
313 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
314 fix up bmp decoder to:
315 - adds 16 bpp bmp support (bug #53884)
316 - adds OS/2 1.x format bmp support (bug #54964)
317 - adds 4 bpp RLE compressed bmp support
318 - adds 1 bpp colormap support
319 - fixes negative height (top down) bmp support
321 2001-05-25 Hans Breuer <hans@breuer.org>
323 * gdk_pixbuf.def : reflect Havoc's recent api change
325 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
327 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
330 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
332 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
334 2001-05-04 Havoc Pennington <hp@redhat.com>
336 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
337 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
340 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
341 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
342 confusion of using "src" instead of "p".
343 (pixops_composite_color_nearest): Use a more accurate (and
344 correct, to begin with) compositing method. This cures checks
345 showing through on images with no alpha.
347 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
350 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
352 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
353 area_updated signal to use signed ints. Removed animation-related
356 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
359 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
360 all the pesky details. Remove old frame-based API. Make
361 GdkPixbufAnimation an abstract base class, derived by the loaders.
363 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
365 * Makefile.am (LDADDS): Add $(MATH_LIB).
367 2001-04-18 Havoc Pennington <hp@redhat.com>
369 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
372 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
374 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
375 so we don't try to get <gtk/gtkobject.h> from standard search
378 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
379 add gdk-pixbuf-marshal.list to EXTRA_DIST.
380 take gdk-pixbuf-marshal.h out of _la sources.
382 2001-03-19 Tor Lillqvist <tml@iki.fi>
384 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
386 * gdk_pixbuf.def: Update.
388 * pixbufloader_*.def: Just export the fill_vtable functions now.
390 2001-03-18 Mike Kestner <mkestner@ameritech.net>
392 * make-inline-pixbuf.c (main): Added logic to remove output when
395 2001-03-14 Havoc Pennington <hp@redhat.com>
397 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
398 from gdk-pixbuf-marshal.h, fixes parallel makes.
400 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
402 * test-gdk-pixbuf.c: fixed includes.
404 2001-02-18 Havoc Pennington <hp@pobox.com>
406 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
407 (gdk_pixbuf_get_named_module): prepend underscore
408 (gdk_pixbuf_get_module): prepend underscore
410 2001-02-19 Havoc Pennington <hp@redhat.com>
412 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
414 2001-02-17 Havoc Pennington <hp@pobox.com>
416 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
418 2001-02-07 Alexander Larsson <alexl@redhat.com>
420 * io-xpm.c (free_buffer):
421 Use g_free, since the buffer is allocated with g_try_alloc().
423 2001-02-06 Christophe Merlet <redfox@eikonex.org>
425 * gdk-pixbuf-data.c: Fixes a minor typo.
427 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
429 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
430 we finally need the gobject->gruntime rename.
432 * *.c: scratched calls to g_type_init(), there's simply no point in
433 doing that, use gtk_init().
435 2001-02-01 Havoc Pennington <hp@pobox.com>
437 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
438 in struct to "priv" for C++
440 2001-01-31 Havoc Pennington <hp@pobox.com>
442 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
444 2001-01-26 Havoc Pennington <hp@redhat.com>
446 * gdk-pixbuf-io.c (mname): fix included modules case.
448 2001-01-22 Havoc Pennington <hp@redhat.com>
450 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
451 from gdk_pixbuf_load_module
453 2001-01-22 Havoc Pennington <hp@redhat.com>
455 * Makefile.am: Add built marshaller files to support
456 GdkPixbufLoader signals
458 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
459 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
460 module location, rather than acting as a fallback, because we are
461 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
463 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
465 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
466 from gtk, and add error to close(), because stop_load may do
467 parsing of the image.
469 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
471 * io-*.c: make individual operations static, and add fill_vtable
472 functions which are exported. Fix the collection of type warnings
473 that surfaced, including a number of functions that didn't
474 properly take a GError and some that weren't
475 const-correct. Involved adding error handling for a few loaders.
477 * gdk-pixbuf-io.h: Add error reporting to stop_load function
479 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
480 a function that fills in the GdkPixbufModule vtable, instead of
481 looking up all the image functions individually; this means we
482 can get type safety within modules for the loader functions.
483 Also it means you don't have to keep the statically compiled and
484 GModule versions in sync.
486 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
488 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
490 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
492 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
495 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
497 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
500 2001-01-20 John Harper <jsh@eazel.com>
502 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
503 collision between Xlib's RdBitF.c and io-tiff.c
505 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
508 [ merged from stable gdk-pixbuf module. Untested, but it
509 compiles, and works fine in the stable module ]
511 2001-01-18 Tor Lillqvist <tml@iki.fi>
513 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
514 g_win32_get_package_installation_subdirectory() function. No need
515 to include windows.h.
516 (gtk_win32_get_installation_directory): Remove this then.
518 2001-01-01 Havoc Pennington <hp@redhat.com>
520 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
521 @LIBTOOL_EXPORT_OPTIONS@
523 2000-12-30 Tor Lillqvist <tml@iki.fi>
525 * gdk_pixbuf.def: Update.
527 2000-12-16 Havoc Pennington <hp@pobox.com>
529 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
530 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
531 (gdk_pixbuf_frame_copy): new function
532 (gdk_pixbuf_frame_free): new function
533 (gdk_pixbuf_frame_get_type): new function
534 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
536 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
538 * Makefile.am: Add -avoid-version for all modules.
540 2000-11-13 Havoc Pennington <hp@redhat.com>
542 * io-png.c (png_simple_error_callback): fix error message to not
543 say "save" since it's used for loading
545 2000-11-11 Hans Breuer <Hans@Breuer.Org>
547 * gdk-pixbuf-io.c : Fix all function prototype macros for self
548 contained image handlers (!USE_G_MODULE). Files to save should
549 be opened in binary mode, fopen(s, "wb").
551 * io-xpm.c : added HAVE_UNISTD_H condition
553 2000-11-11 Tor Lillqvist <tml@iki.fi>
555 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
557 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
558 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
559 mktemp() and open()).
561 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
563 2000-11-01 Havoc Pennington <hp@pobox.com>
565 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
566 a pixbuf pointing to a subregion of another pixbuf.
568 2000-10-16 Tor Lillqvist <tml@iki.fi>
570 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
572 2000-10-16 Havoc Pennington <hp@redhat.com>
574 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
575 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):

582 * gdk-pixbuf-util.c: include string.h
584 * io-*.c: add error reporting
586 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
589 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
591 * gdk-pixbuf-io.h: Add GError** to load_increment and load
594 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
595 a G_FILE_ERROR if we fail to write or close the file.
597 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
598 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
599 the GError naming rules. Add GError** to load functions.
601 2000-10-06 Havoc Pennington <hp@redhat.com>
603 * gdk-pixbuf.h: add GdkPixbufAlphaMode
605 2000-10-06 Havoc Pennington <hp@redhat.com>

633 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
635 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
636 last nights code was still "broken". Should now properly handle
637 all error conditions gracefully.
639 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
641 * gdk-pixbuf/io-pnm.c: Rewrote.

663 2000-07-21 Larry Ewing <lewing@helixcode.com>
665 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
666 xpm at least supports the progressive interface like the one in
667 io-tiff.c. This should be reimplemented as an actual progressive
670 2000-07-19 Jonathan Blandford <jrb@redhat.com>
672 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
674 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael

685 2000-10-06 Havoc Pennington <hp@redhat.com>
687 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
688 consistent with gdk_pixbuf_loader_new_with_type().
689 Return runtime error if a module is missing.
691 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
693 2000-10-05 Havoc Pennington <hp@redhat.com>
695 Pixbuf saving, patch from David Welton.
697 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
698 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
700 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf
702 * io-png.c (gdk_pixbuf__png_image_save): PNG save routine.

707 (gdk_pixbuf_savev): Implement pixbuf saving routines
709 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
712 * gdk-pixbuf.h: Add public save routines; add pixbuf error
715 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
717 2000-10-05 Dan Winship <danw@helixcode.com>
719 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
720 all three of these files are the JPEG image loader. (From
723 2000-10-03 Tor Lillqvist <tml@iki.fi>
725 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
726 gdk-pixbuf's version number in the rule for makefile.mingw itself.
728 * gdk_pixbuf.def: Add new entry points.
730 2000-09-26 Havoc Pennington <hp@redhat.com>
732 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
733 function here, instead of putting it in a private GTK+ file.
735 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
736 enum here for the known formats of inlined pixbufs.
737 Also, #define our file magic here.
739 2000-06-23 Havoc Pennington <hp@redhat.com>
741 * make-inline-pixbuf.c: Small program that creates C variable
742 declarations of inline pixbuf data. This can be read
743 by gdk_pixbuf_new_from_inline.
745 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
746 inline pixbuf data and create a pixbuf from it.
748 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
750 2000-09-07 Tor Lillqvist <tml@iki.fi>
752 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
755 2000-08-12 Tor Lillqvist <tml@iki.fi>
757 * gdk_pixbuf.def: Add missing entry point.
759 2000-08-10 Havoc Pennington <hp@redhat.com>
761 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
762 (s/pixbuf_/pixbufloader_)
764 2000-08-02 Tor Lillqvist <tml@iki.fi>
770 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
772 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
773 one. Fix names of DLLs to have '-' instead of '_'.
775 2000-07-31 Elliot Lee <sopwith@redhat.com>
776 * io-wbmp.c: Some bug fixes - now tested to work.
778 2000-07-27 Elliot Lee <sopwith@redhat.com>
780 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
781 gdk_pixbuf_get_named_module() function to facilitate above change
782 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
783 Implement loader for WBMP format.
784 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
786 2000-07-23 Tor Lillqvist <tml@iki.fi>
791 * pixops/makefile.mingw.in
792 * pixbuf_*.def: New files.
795 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
797 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
798 New function, to get the GTK+ installation directory from
799 the Windows Registry, where the installation program
800 for whatever software includes GTK+ has stored it.
802 Used to avoid having hardcoding the directory where to look for
803 loaders. This function is needed by gtk, too, so it should
804 really be just in one place. Maybe a small static library
805 one level up from here?
807 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
808 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
809 Open file in binary mode. This *is* standard C. (No-op on Unix,
812 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
814 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
816 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
818 * pixops/*.S: The Gas from mingw32 doesn't like the .type
819 pseudo-op. Conditionalise on __MINGW32__, but probably
820 should conditionalise on Gas version instead? Or could we
821 do without .type on all systems?
823 * pixops/timescale.c: Use g_get_current_time()
824 instead of gettimeofday().
826 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
828 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
830 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
832 * gdk-pixbuf.c: Add <string.h> include.
834 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
836 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
837 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
838 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
839 use g_object_new() instead of g_type_create_instance() which
840 is a private function for fundamental type implementations.
842 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
844 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
845 soname scheme for gdk-pixbuf.
847 2000-06-21 Havoc Pennington <hp@pobox.com>
849 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
850 (i.e. derivation is not allowed, and there are no virtual methods
852 (gdk_pixbuf_preinit): Call g_type_init() here.
853 (gdk_pixbuf_init): Add a user-friendly init function, for users
854 of standalone gdk-pixbuf
856 * gdk-pixbuf-animation.c: Convert to GObject, in the same
857 way GdkPixbufAnimation was done.
859 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
860 gdk_pixbuf_finalize() from API, since these are broken and don't
861 make sense with new GObject stuff.
863 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
865 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
866 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
869 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
871 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
872 so I needed something to warm my thighs. Running plain infinite
873 loops on your laptop to make it hot is not very much fun. A demo
874 of the gdk-pixbuf scaling functions is way better, and looks
877 * configure.in (AC_OUTPUT): Added the demo Makefile.
879 * Makefile.am (SUBDIRS): Added the demo directory.
881 2000-06-09 Larry Ewing <lewing@helixcode.com>
883 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
884 setjmp for the png error handler. It seems setting the error
885 handling functions does not avoid the jump, and so not calling
886 setjmp was causing the incremental loader to jump into lala land.
887 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
888 not sure this one is actually required but the docs say it must be
889 set for every call to a png_* function.
890 Also changed the comment to reflect the fact that setting the
891 error handlers does _not_ avoid the longjmp.
893 2000-06-06 Larry Ewing <lewing@helixcode.com>
895 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
896 take frame offest into account when trying to calculate the
897 animation bbox. Also set the width to the width not the height.
898 (gdk_pixbuf_loader_animation_done): cycle over the frames to
899 calculate bbox because now we finally have all the offset
900 information for each frame.
902 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
904 * configure.in: add some gtk parameters to the
905 GDK_PIXBUF_LIB²S and GDK_PIXBUG_INCLUDEDIR vars. One more
906 fight in my crusade for strange prefix compile...
908 2000-05-30 Not Zed <NotZed@HelixCode.com>
910 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
911 Initialise the error handler exit routine to our own. Note this
912 means that every function that accesses the jpeg lib on this
913 object MUST do a setjmp.
914 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
915 lib for handling fatal error.
916 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
917 your applications dont quit if there's a jpeg error!
919 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
921 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
922 from Frank de Lange <frank@unternet.org>.
924 2000-05-09 Darin Adler <darin@eazel.com>
926 * gdk-pixbuf/test-gdk-pixbuf.c:
927 Fixed includes to get rid of accidental GNOME dependency.
929 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
930 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
932 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
934 * configure.in: Bumped version number to 0.8.0.
936 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
937 file was not being distributed.
939 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
941 2000-05-09 Darin Adler <darin@eazel.com>
943 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
944 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
945 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
946 formats to 32-bit formats to re-use the high bits of the color values
947 so that white maps to full white.
949 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
951 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
952 detailed information about the structure and algorithms
953 of pixops so people can fix it instead of breaking it.
955 2000-05-04 Darin Adler <darin@eazel.com>
957 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
958 (composite_pixel), (composite_line):
959 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
960 Now that Owen explained the algorithm, I think I implemented it
961 right for the cases where the destination pixbuf is not opaque.
962 The test does seem to confirm it.
964 2000-05-04 Darin Adler <darin@eazel.com>
966 * gdk-pixbuf/.cvsignore:
967 * gdk-pixbuf/Makefile.am:
968 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
969 (load_pixel), (simple_composite_test_one),
970 (simple_composite_test_one_type), (simple_composite_test), (main):
971 Added some tests of composite to highlight problems in the old
972 implementation. These tests run without any user interaction.
973 Just do "make check".
975 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
976 (composite_pixel), (composite_line): Fix composite to do a textbook
977 "A over B" composite. This was clearly the intent, and it was easy
978 to fix the code to do it. (Note to those that read my earlier tries
979 at a patch; this version fixes typos that were present in all
980 my patch attempts. I checked the final version by adding more tests.)
982 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
984 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
985 offset y coordinate accordining to render_y0.
987 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
990 2000-04-22 James Henstridge <james@daa.com.au>
992 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
993 package to the devel package. The only file installed in bin is
994 gdk-pixbuf-config, which belongs in -devel. This should allow having
995 multiple versions of the main gdk-pixbuf package installed.
997 2000-04-17 Karl Eichwalder <ke@suse.de>
999 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
1000 Reported by Jens Finke.
1002 2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
1004 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
1005 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
1007 2000-04-13 James Henstridge <james@daa.com.au>
1009 * configure.in: when performing the configure check to see if
1010 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
1011 rather than the other way round. Also, call AC_MSG_RESULT in the
1012 even that dynamic modules were not supported.
1014 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
1016 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
1017 hook to the last unref operation.
1019 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
1020 function to set the last unref handler for a pixbuf.
1021 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
1022 It calls the pixbuf's destroy notification function and frees the
1023 GdkPixbuf structure itself.
1024 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
1027 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
1028 for the last unref handler and its user data.
1030 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
1031 g_new0() to allocate the pixbuf.
1033 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
1034 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
1035 was not specifying the `frame' argument.
1037 * gdk-pixbuf/gdk-pixbuf-animation.c
1038 (gdk_pixbuf_animation_get_width): Fixed docstring.
1039 (gdk_pixbuf_animation_get_height): Likewise.
1040 (gdk_pixbuf_animation_get_num_frames): Likewise.
1041 (gdk_pixbuf_animation_get_frames): Likewise.
1043 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1046 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1048 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1050 * doc/tmpl/refcounting.sgml: Updated with the information about
1051 the last unref handler.
1053 * doc/tmpl/*.sgml: Markup tweaks.
1055 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1056 update the libtool version number for libgnomecanvaspixbuf as
1058 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
1059 as well, or the old ones won't work with the new stuff. Also,
1060 renamed the modules as follows.
1062 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
1063 modules are called "libpixbufloader-<format>.so" instead of
1064 "libpixbuf-<format>.so". They needed renaming so that the new
1065 loaders won't overwrite the old ones; even with the versioning
1066 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
1069 2000-04-12 Paolo Molaro <lupus@debian.org>
1071 * .cvsignore, src/.cvsignore: shut up cvs.
1073 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
1075 Most of this patch is based on a patch by Havoc Pennington
1076 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
1077 remove the libart dependency.
1079 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
1080 (GdkColorspace): New enum that for now only contains
1082 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
1083 notification function.
1084 (GdkInterpType): New num with interpolation types.
1086 * *.[ch]: Replace the libart stuff with our own stuff.
1088 * pixops/*.[ch]: Likewise.
1090 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
1091 declarations of the GdkPixbuf structures.
1093 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
1095 (gdk_pixbuf_get_format): Constify.
1096 (gdk_pixbuf_get_n_channels): Constify.
1097 (gdk_pixbuf_get_has_alpha): Constify.
1098 (gdk_pixbuf_get_bits_per_sample): Constify.
1099 (gdk_pixbuf_get_pixels): Constify.
1100 (gdk_pixbuf_get_width): Constify.
1101 (gdk_pixbuf_get_height): Constify.
1102 (gdk_pixbuf_get_rowstride): Constify.
1104 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
1107 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
1108 bits_per_sample argument; currently only 8 bits per sample are
1111 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):

1624 2000-01-05 Owen Taylor <otaylor@redhat.com>
1626 * gdk-pixbuf/pixops/README: Added a README with a TODO
1627 and some explainations of the algorithms.
1629 * gdk-pixbuf/testpixbuf-scale.c: Set a background pixmap of None
1630 to reduce flashing when resizing.
1632 2000-01-05 Owen Taylor <otaylor@redhat.com>
1634 * gdk-pixbuf/pixops/: Directory full of pixel data scaling
1635 code that will eventually migrate into libart.
1637 * configure.in acconfig.h: Add checks for MMX compiler support
1639 * gdk-pixbuf/gdk-pixbuf.h gdk-pixbuf/gdk-pixbuf-scale.c:
1640 Nice wrapper routines for the code in pixops that operate
1641 on pixbufs instead of raw data.
1643 * gdk-pixbuf/testpixbuf-scale: Test program for scaling
1646 2000-01-05 Jonathan Blandford <jrb@redhat.com>
1648 * doc/tmpl/animation.sgml: Documentation changes.
1650 2000-01-01 Federico Mena Quintero <federico@helixcode.com>
1652 * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
1653 counting to animations. A web browser may want to share a single
1654 copy of an animated GIF if it appears multiple times in a web
1657 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
1658 animation functions here.
1659 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
1660 animation if the loader does not support multiframe loading and
1661 the single-frame load returned NULL. Check that the filename is
1662 not NULL. Updated inline documentation.
1663 (gdk_pixbuf_animation_ref): New function.
1664 (gdk_pixbuf_animation_unref): New function.
1665 Removed gdk_pixbuf_animation_destroy() in favor of reference
1668 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1669 Prettified. Made ref_count assertion more paranoid. Check that
1670 the filename is not NULL.
1671 (gdk_pixbuf_get_module): Use guchar * and guint for buffer and
1673 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
1676 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
1677 with a reference count of 1.
1679 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
1680 gdk-pixbuf-animation.c.
1682 * doc/tmpl/animation.sgml: Populated. It is still missing a
1683 description of the overlay modes.
1685 * doc/gdk-pixbuf-sections.txt: Added the animation section. Moved
1686 the canvas item section to the end, as it will be moved later to
1689 * doc/gdk-pixbuf.sgml: Added the animation section.
1691 * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
1693 1999-12-26 Peter Teichman <pat@gnu.org>
1695 * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add
1696 $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker.
1697 This closes bug #4676.
1699 1999-12-23 Havoc Pennington <hp@pobox.com>
1701 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
1702 set to NULL here (specifically context->animation) was not being
1703 set to NULL. use g_new0() to alloc the struct.
1705 1999-12-20 Jonathan Blandford <jrb@redhat.com>
1707 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
1708 correctly. Progressive loading needs some work, but that all
1709 needs doing from the gdk-pixbuf-loader end, not here.
1711 1999-12-17 Jonathan Blandford <jrb@redhat.com>
1713 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
1714 moved the file here. It seems natural to put this function here,
1715 as that's where the gdk_pixbuf_new_from_file function is, but it's
1716 still a little convoluted. The source files might be played with
1719 1999-12-14 Jonathan Blandford <jrb@redhat.com>
1721 * gdk-pixbuf/gdk-pixbuf-loader.c
1722 (gdk_pixbuf_loader_get_animation): Gets the animation from the
1725 1999-12-16 Federico Mena Quintero <federico@redhat.com>
1727 * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
1728 before using the GdkPixbuf rendering functions. Thanks to Joe
1729 Shaw <joe@off.net> for pointing this out.
1731 1999-12-13 Federico Mena Quintero <federico@redhat.com>
1733 * gdk-pixbuf/gnome-canvas-pixbuf.c
1734 (gnome_canvas_pixbuf_class_init): Renamed arguments to
1735 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
1736 consistency with the new canvas.
1737 (PixbufPrivate): Do the same renaming in the structure fields, for
1740 * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.
1742 1999-12-12 Federico Mena Quintero <federico@redhat.com>
1744 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
1745 conditional to see whether to link $(GNOME_LIBS) or not.
1747 1999-12-10 Jonathan Blandford <jrb@redhat.com>
1749 * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API.
1751 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
1752 make a warning go away.
1754 * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations.
1756 * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for
1759 1999-12-09 Michael Zucchi <zucchi@zedzone.mmc.com.au>
1761 * gdk-pixbuf/gdk-pixbuf.h: Enable gdk_pixbuf_get_from_drawable()
1764 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
1765 Filled in body of function.
1766 (rgbconvert): Added GdkColormap parameter, and to all conversion
1768 (convert_real_slow): New function - should convert ANY visual/data
1769 format properly, but it aint fast. Used as a fallback when an
1770 optimised routine wont match.
1771 (rgbconvert): Do very specific tests on the data format to verify
1772 properly if the optimised version will do, otherwise use the
1773 fallback function for all other data formats.
1775 * gdk-pixbuf/Makefile.am: Re-enabled building of
1776 textpixbuf-drawable.
1778 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
1779 gdk_pixbuf_get_from_drawable().
1781 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
1783 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
1784 bug on two occasions.
1785 * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu
1786 function to the generic glib one.
1788 1999-12-08 Federico Mena Quintero <federico@redhat.com>
1790 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
1791 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
1792 checks and API definition. The body needs filling in and it needs
1793 to do the Right Thing(tm) for pixmaps plus the given colormap and
1794 windows and their own colormaps.
1796 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
1797 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
1799 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
1801 * doc/tmpl/from-drawables.sgml: Populated.
1803 * doc/gdk-pixbuf.sgml: Added the from-drawables section.
1805 * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml.
1807 * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs
1810 1999-12-07 Federico Mena Quintero <federico@redhat.com>
1812 * doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about
1813 reference counting for GdkPixbuf structures.
1815 1999-12-07 Martin Baulig <martin@home-of-linux.org>
1817 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
1818 include $(GNOME_LIBS) here.
1820 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
1822 Added missing "include <string.h>" to:
1823 * gdk-pixbuf/io-ras.c
1824 * gdk-pixbuf/io-bmp.c
1825 * gdk-pixbuf/io-ico.c
1827 1999-12-06 Federico Mena Quintero <federico@redhat.com>
1829 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
1832 1999-12-05 Federico Mena Quintero <federico@redhat.com>
1834 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
1835 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
1836 want, send me a patch to do the conditional stuff properly.
1837 Otherwise, please read the GNOME Programming Guidelines,
1838 especially the "CVS policies" section.
1840 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
1842 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
1844 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
1846 * gdk-pixbuf/io-ico.c: Bug in palet-size
1849 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
1851 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
1852 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
1854 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
1856 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
1859 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
1860 (Windows Cursor files). These are identical to .ICO files,
1861 except for the signature and 2 extra fields for the hotspot.
1863 1999-12-03 Federico Mena Quintero <federico@redhat.com>
1865 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):
1866 Removed unused variable `item'.
1868 1999-12-03 Jonathan Blandford <jrb@redhat.com>
1870 * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
1871 explain this function better.
1873 1999-12-02 Federico Mena Quintero <federico@redhat.com>
1875 Source files moved from src/ to gdk-pixbuf/, to be consistent with
1878 * doc/Makefile.am: Modified for the new source directory.
1880 * configure.in: Likewise.
1882 * Makefile.am: Likewise.
1884 * autogen.sh: Likewise.
1886 * gdk-pixbuf/Makefile.am: Likewise.
1888 1999-12-02 Federico Mena Quintero <federico@redhat.com>
1890 * src/testpixbuf.c: #include <config.h>, and fix includes.
1892 * src/testpixbuf-drawable.c: #include <config.h>, and fix includes.

1900 * src/io-pnm.c: Fix inlcudes, and do not include more stuff than needed.
1902 * src/io-png.c: Fix includes.
1904 * src/io-ico.c: Fix includes, and do not include more stuff than needed.
1906 * src/io-gif.c: Fix includes, and do not include more stuff than needed.
1908 * src/io-bmp.c: Fix includes, and do not include more stuff than needed.
1910 * src/gnome-canvas-pixbuf.c: Fix includes.

1914 * src/gdk-pixbuf-util.c: Fix includes.
1916 * src/gdk-pixbuf-render.c: Fix includes.
1918 * src/gdk-pixbuf-io.h: Fix includes.
1920 * src/gdk-pixbuf-drawable.c: Fix includes.
1922 * src/gdk-pixbuf-drawable.h: Use angle brackets for the gdk-pixbuf
1925 * src/gdk-pixbuf-data.c: Fix includes.
1927 * src/gdk-pixbuf-loader.c: #include <config.h>
1929 * src/gdk-pixbuf-loader.h: Use angle brackets for the gdk-pixbuf
1932 * src/Makefile.am: Commented out the gdk-pixbuf-drawable stuff,
1933 since it is not finished.
1935 * src/gdk-pixbuf.h: Removed unused transformation prototypes.
1937 * src/gdk-pixbuf-util.c: New file with utility and convenience
1938 functions for pixbufs.
1940 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c.
1942 * doc/gdk-pixbuf-sections.txt: Added section for utility functions.
1944 * doc/Makefile.am (tmpl_sources): Added tmpl/util.sgml.
1946 * doc/gdk-pixbuf.sgml: Added the utilities section.
1948 * doc/tmpl/util.sgml: Documentation for the utility functions.
1950 1999-11-29 Owen Taylor <otaylor@redhat.com>
1952 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
1953 Keep the mask around until after we draw ... since
1954 the GC changes aren't flushed to the X server until we
1955 draw, destroying it before that may result in BadPixmap
1958 1999-11-30 Havoc Pennington <hp@pobox.com>
1960 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
1962 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
1964 1999-11-29 Federico Mena Quintero <federico@redhat.com>
1966 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
1967 should be made conditional, not blindly commented out.
1969 1999-11-29 Jonathan Blandford <jrb@redhat.com>
1971 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
1972 handle .ico files. Cool.
1974 1999-11-24 Jonathan Blandford <jrb@redhat.com>
1976 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
1979 1999-11-24 James Henstridge <james@daa.com.au>
1981 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
1982 top builddir rather than src. This still builds fine, and does not
1983 get gtk-doc into an infinite loop when trying to find all the source
1986 1999-11-23 Jonathan Blandford <jrb@redhat.com>
1988 * Removed #PRAGMA } from headers. Also, make compile if you don't
1989 have it installed, already.
1991 1999-11-22 Federico Mena Quintero <federico@redhat.com>
1993 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
1994 temporary buffer to the size of the interesction of the bounding
1995 box and the expose area, not the whole expose area. This speeds
1998 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
1999 not paint black on the mask, since we already cleared it in a
2000 single gdk_draw_rectangle() operation.
2002 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
2004 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
2006 1999-11-22 Havoc Pennington <hp@pobox.com>
2008 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
2009 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
2010 dependencies to LIBADD variables for loadable modules. Necessary
2011 for a Java dynamic loading thing to be able to figure it out.
2013 1999-11-22 Havoc Pennington <hp@pobox.com>
2015 * src/io-png.c (image_load_increment): Call the update_area
2016 callback depending on the number of rows loaded in this increment.
2018 * src/testpixbuf.c (main): slow down the progressive load demo
2020 1999-11-16 Havoc Pennington <hp@pobox.com>
2022 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
2024 1999-11-22 Jonathan Blandford <jrb@redhat.com>
2026 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
2027 for srcdir != buildir != . Beats me why; I can't figure it out.
2028 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
2030 1999-11-21 Jonathan Blandford <jrb@redhat.com>
2032 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
2033 <arjan@fenrus.demon.nl>
2035 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2037 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
2038 Rework/reorder of the code. Each case has been separated into
2039 another function; its big but it should be quick.
2040 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
2041 opaque alpha information. Not all depths/formats have been
2042 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
2044 1999-11-17 Larry Ewing <lewing@gimp.org>
2046 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2047 implement the bounds method correctly.
2048 (compute_viewport_affine): compute the affine need to fit the
2049 image within the viewport given by the args.
2050 (compute_render_affine): call compute_viewport_affine.
2052 1999-11-16 Havoc Pennington <hp@pobox.com>
2054 * src/gdk-pixbuf-drawable.h: Use includes from the current
2055 directory, not the system directory.
2057 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
2059 * src/testpixbuf-drawable.c: use includes from the current directory
2060 rather then from the system include directory as gdk-pixbuf
2061 includes are not yet installed when this is compiled.
2063 1999-11-13 Cody Russell <bratsche@dfw.net>
2064 * src/testpixbuf-drawable.c: Added a test program for drawable
2067 * src/Makefile.am: Build testpixbuf-drawable.
2069 1999-11-12 Cody Russell <bratsche@dfw.net>
2071 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.
2073 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2075 * doc/tmpl/gdk-pixbuf-loader.sgml: Populated.
2077 * doc/gdk-pixbuf.signals: Put in the real names of signal
2080 * src/gdk-pixbuf-loader.c: Improved documentation comments.
2082 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2084 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
2087 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
2088 correctly. Patch from Arjan to do so.
2090 1999-11-10 Michael Fulbright <drmike@redhat.com>
2092 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
2095 * src/testpixbuf.c: Added final queued draw when done loading image.
2097 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2099 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
2102 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2104 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
2107 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2109 * src/io-png.c: Fixed some incompatible pointer initializations.
2111 * src/io-jpeg.c (image_load_increment): Remove unused variable.
2113 1999-11-09 Michael Fulbright <drmike@redhat.com>
2115 * src/testpixbuf.c: Fixed it to use timeout to read from file
2116 for progressive loading. Set TBF_KBPS=n, where n is the number of
2117 kilobytes/second to simulate in downloading. n has to be an integer.
2119 * src/io-jpeg.c: Slight cosmetic cleanup.
2121 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
2122 PBM loading has a similar problem and will address tomorrow.
2124 1999-11-09 Havoc Pennington <hp@pobox.com>
2126 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
2127 gdk-pixbuf-drawable stuff.
2129 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2131 * configure.in: Bumped version number to 0.4.
2133 1999-11-09 Michael Fulbright <drmike@redhat.com>
2135 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
2136 all types of PNM files now.
2138 * src/io-jpeg.c (image_load_increment): Figured out problem with
2139 loading Progressive JPEG's progressively (say that 10 times fast).
2140 Currently for Progressive JPEG's the entire image is loaded before
2141 it is displayed. libjpeg supports a fancier mechanism which I may
2144 With these changes all JPEG formats appear to load properly for me.
2146 1999-11-08 Jonathan Blandford <jrb@redhat.com>
2148 * src/io-ras.c (image_load_increment): Final patch from Arjan.
2149 Seems to do progressive loading.
2151 1999-11-08 Michael Fulbright <drmike@redhat.com>
2153 * src/io-pnm.c image_load (): Fixed so we do not create a separate
2154 pixel buffer when reading in image - we reuse the pixel data in
2155 the GdkPixbuf structure instead.
2157 1999-11-08 Michael Fulbright <drmike@redhat.com>
2159 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
2160 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
2161 I can't seem to find a utility to convert into this format.
2162 Next is to add progressive loading support for the PNM format.
2164 1999-11-07 Federico Mena Quintero <federico@redhat.com>
2166 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
2167 of the width, height, x, and y setting and pixels arguments.
2169 1999-11-05 Jonathan Blandford <jrb@redhat.com>
2171 * src/io-ras.c (image_load): third patch. Now it seems to load.
2173 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
2174 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
2176 * src/io-ras.c (image_load): new file from Arjan van de Ven
2177 <arjan@fenrus.demon.nl> to begin the ras loader.
2179 1999-11-05 Federico Mena Quintero <federico@redhat.com>
2181 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
2182 for internal use only.

2221 separately. Fix GNOME_LIBS to be correct in "no gnome installed
2224 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
2227 Patch untested in the inside-gnome-libs case, I need to commit
2228 then check out to the gnome-libs I'm using.
2230 1999-11-04 Michael Fulbright <drmike@redhat.com>
2232 * src/io-jpeg.c (image_begin_load): Add update_func callback.
2233 * src/io-jpeg.c (image_load_increment): Call updated callback when
2234 new graphic data decoded.
2236 1999-11-04 Jonathan Blandford <jrb@redhat.com>

2261 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2263 * configure.in: Removed libgif stuff now that we do not depend on it.
2264 Added the necessary cruft for gtk-doc.
2266 * src/Makefile.am: Unconditionally build the GIF loader.
2268 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2270 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
2271 Added a lot of comments to the file.

2276 1999-11-03 Michael Fulbright <drmike@redhat.com>
2278 * src/io-jpeg.c (image_load_increment): Further removal of
2279 bugginess in local buffering code. Handles grayscale jpegs
2282 * src/io-jpeg.c (image_load_stop): Was freeing local context
2283 for jpeg library before calling jpeg_decompres_finish ().
2285 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2287 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
2289 (gif_get_lzw): set the transparency to the right val.
2291 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2293 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
2294 Initiailize the x and y fields.
2295 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
2296 (PixbufPrivate): Renamed need_size_update to need_xform_update.
2297 (recompute_bounding_box): Do not use temporary values.
2299 1999-11-03 Jonathan Blandford <jrb@redhat.com>

2309 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
2310 render_affine calculation for x,y offsets.
2311 (gnome_canvas_pixbuf_set_arg): add x,y args.
2312 (gnome_canvas_pixbuf_get_arg): add x,y args.
2313 (recompute_bounding_box): simply code using ArtDrect and the

2317 1999-11-03 Federico Mena Quintero <federico@redhat.com>
2319 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
2320 doofus. Return a distance, not a boolean, for opaque images.
2322 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
2323 rounding of bounding box coordinates.
2324 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
2325 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
2327 1999-11-03 Jonathan Blandford <jrb@redhat.com>
2329 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
2331 1999-11-03 Michael Fulbright <drmike@redhat.com>
2333 * src/io-jpg.c (image_load_increment): Fixed code which moved
2334 buffer around as new data comes in to work properly. JPEG progressive
2335 loading should be working now except for grayscale JPEG's, which I
2336 will look into next.
2338 1999-11-03 <sopwith@redhat.com>
2339 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
2340 Also put dot printing back in.
2342 1999-11-03 <jrb@redhat.com>
2344 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
2347 1999-11-02 Cody Russell <bratsche@dfw.net>
2348 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
2349 if part of the requested image is offscreen, rather than clipping
2352 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2354 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
2355 for interlacing and progressive loading.
2357 1999-11-02 Cody Russell <bratsche@dfw.net>
2358 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
2359 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
2361 1999-11-02 Jonathan Blandford <jrb@redhat.com>
2363 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
2364 It's a little slow though. )-:
2366 1999-11-02 Elliot Lee <sopwith@redhat.com>
2367 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
2368 write/load_increment operations const-correct.
2370 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2372 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
2373 Implemented the ::point() method. We do a simple containment test
2374 instead of a full distance calculation since the canvas is going
2375 to change to that scheme, anyways.
2377 1999-11-02 Elliot Lee <sopwith@redhat.com>
2379 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
2380 that are read from the input file.
2382 1999-11-02 Larry Ewing <lewing@gimp.org>
2384 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
2386 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
2389 1999-11-02 Federico Mena Quintero <federico@redhat.com>
2391 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
2392 affine computation code from ::draw() to here, since it is needed
2393 by ::point() as well.
2395 1999-11-02 Elliot Lee <sopwith@redhat.com>
2397 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
2398 three functions, and eliminate duplication of code from write()
2399 and close(). Also fix bug where the 128-byte header was being
2402 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2403 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
2404 bounding box computation.
2406 1999-11-01 Federico Mena Quintero <federico@redhat.com>
2408 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
2409 Drawing affines seem to work. Bounding box is fubared. ::point()
2410 is not implemented. This is a work in progress.
2412 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
2415 * configure.in: Sigh. We need to link in libgnomeui for the
2416 canvas stuff. This mess will disappear when gdk-pixbuf gets
2417 folded into gnome-libs.
2419 1999-10-30 Jonathan Blandford <jrb@redhat.com>
2421 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
2422 the right size, at a minimum, even if the image is squished and
2424 (ReadImage): lets get the offset right. This will let transparent
2427 1999-10-29 Michael Fulbright <drmike@redhat.com>
2429 * src/io-jpeg.c: image_load_increment(): Fixed bug when
2430 image width was not a multiple of 4 - always use the
2431 gdk_pixbuf rowstride to increment pointers!
2433 1999-10-29 Michael Fulbright <drmike@redhat.com>
2435 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
2436 Currently does not handle either progressive jpeg files (jpeg
2437 files with multiple scans at different quality settings), but
2438 I plan on adding this support soon. These are fairly rare in
2439 my experience, so it shouldn't slow people down too much.
2440 Grayscale jpegs also don't work but that should be easy to fix.
2442 1999-10-29 Michael Fulbright <drmike@redhat.com>
2444 * src/testpixbuf.c: Added title to windows so you can identify
2445 progressive and file windows.
2447 1999-10-29 Michael Fulbright <drmike@redhat.com>
2449 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
2450 load the image handler when we determine the image type.
2452 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
2453 previously static function load_image_handler () to
2454 a public function gdk_pixbuf_load_module (). It is needed in
2455 gdk-pixbuf-loader.c to load image handler modules. This function
2456 is different from gdk_pixbuf_get_module (), which only returns
2457 a reference to the required handler, because it actually loads
2458 the handler into memory. Both actions should possibly be combined
2459 in a convenience function since one w/o the other doesn't seem to
2462 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2464 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
2467 1999-10-28 Federico Mena Quintero <federico@redhat.com>
2469 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
2470 function to render a portion of a pixbuf to a drawable. Ignores
2471 alpha information and takes in a GC.
2472 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
2473 portion of a pixbuf to a drawable. It automatically creates a GC
2474 and a clipping mask for alpha pixbufs.
2476 1999-10-28 Jonathan Blandford <jrb@redhat.com>
2478 * src/gdk-pixbuf.h: turned convenience macros into convenience
2479 functions so some error checking could be added.
2481 * src/io-tiff.c (image_load_increment): started work on the tiff
2482 non-incremental loader.
2483 (image_begin_load): Finished the incremental loader.
2485 * src/io-gif.c (image_load_increment): started work on the gif
2488 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
2490 1999-10-27 Federico Mena Quintero <federico@redhat.com>
2492 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
2493 function to threshold a pixbuf's alpha channel into a bitmap.
2495 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
2496 contemplate future extensions to ArtPixBuf's formats.
2498 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
2500 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
2501 macros to fetch the ArtPixBuf's fields.
2503 1999-10-27 Havoc Pennington <hp@pobox.com>
2505 * src/testpixbuf.c (main): Display the progressive load
2507 * src/io-png.c (setup_png_transformations): Break transformation
2508 code into separate function
2509 (png_info_callback): Use setup_png_transformations
2511 1999-10-27 Havoc Pennington <hp@pobox.com>
2513 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
2514 properly whether the XPM module has already been loaded
2515 (gdk_pixbuf_new_from_file): Check properly if loader module
2516 was already loaded (was checking if load symbol was present
2517 in order to decide whether to re-load; should check module !=
2518 NULL, then load != NULL)
2519 (image_handler_load): Check in present working directory,
2520 makes it easier to debug for now
2521 (file_formats): This array initializer was seriously on crack,
2522 was assigning a function pointer to a GModule*
2524 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
2526 1999-10-27 Havoc Pennington <hp@pobox.com>

2534 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
2535 GdkPixbufLoader, not a GtkObject.
2536 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
2537 (gdk_pixbuf_loader_get_type): Documented.
2538 (gdk_pixbuf_loader_class_init): Initialize the parent class
2540 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
2541 class destroy function.
2542 (gdk_pixbuf_loader_new): Documented.
2543 (gdk_pixbuf_loader_finalize): Call the parent class finalize
2545 (gdk_pixbuf_loader_write): Use size_t for count.
2547 1999-10-27 Michael Fulbright <drmike@redhat.com>
2549 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
2550 logic so we only try to close loader if it wasn't previously closed.
2552 1999-10-27 Michael Fulbright <drmike@redhat.com>
2554 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of
2555 pixbuf_loader properly initialized.
2557 * src/testpixbuf.c: Made sure we cleanup pixbuf_loader properly
2560 1999-10-26 Jonathan Blandford <jrb@redhat.com>

2580 * configure.in (CFLAGS): Patch from Uwe Koloska
2581 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
2583 1999-10-22 Havoc Pennington <hp@pobox.com>
2585 * src/io-xpm.c (mem_buffer): Clean up stupid
2586 increment-inside-array-dereference thing
2588 * src/testpixbuf.c: Add XPM data tests.
2590 * src/io-xpm.c: Make the XPM data buffer const, fix const
2591 correctness throughout the code.
2593 1999-10-22 Havoc Pennington <hp@pobox.com>
2595 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

2603 function, loads pixbuf from xpm data
2604 (image_handler_load): Add g_return_if_fail() to ensure the same
2605 module isn't loaded twice. Add g_module_symbol() to scan for XPM
2608 1999-10-22 Federico Mena Quintero <federico@redhat.com>
2610 * src/io-png.c (image_load): Patch from Kristian Hogsberg
2611 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
2612 buffers; the rows can be read in directly into the main pixel
2615 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2617 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
2619 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2621 * configure.in: Bumped version number to 0.3.
2623 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
2624 version number for the library.
2626 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2628 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
2629 all memory management of the buffer is done by libart.

2632 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
2634 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
2635 terms of the libart functions. Removed the old code.
2637 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
2638 symbols. Saving will not be implemented in GdkPixbuf.
2640 * src/io-gif.c: Removed the saving stub.
2641 (image_load): Fixed memory management to fail gracefully if we run
2642 out of memory while loading the image. Close the gif file when we
2643 are done. This still needs more error handling for the DGif
2646 * src/io-jpeg.c (image_load): Some robustness fixes.
2648 * src/io-png.c: Removed the saving stuff.
2649 (image_load): Some memory management fixes.

2659 * autogen.sh: use subautogen.sh
2661 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2663 * src/*: Reindented to use the GNOME Indentation. Renamed
2664 GdkPixBuf to GdkPixbuf, for consistency with the function names
2665 (and it is also easier to type) :-)
2667 1999-10-18 Havoc Pennington <hp@pobox.com>
2669 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
2671 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
2673 1999-10-18 Havoc Pennington <hp@pobox.com>
2675 * Makefile.am (SUBDIRS): Remove "macros"
2677 * configure.in: Don't use GNOME_INIT, handle case where we are
2678 inside gnome-libs. AM_PATH_GTK for the GIF test
2680 * src/Makefile.am: Change flags to work without libgnomeui,
2681 comment out testpixbuf for now
2683 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2685 * configure.in: Use $GTK_LIBS as the extra libs when checking for
2686 libgif/libungif, as they need the X libraries. Fixes bug #2472.
2688 1999-10-10 Cody Russell <bratsche@dfw.net>
2689 * src/gdk-pixbuf-drawable.c: core function now determines whether
2690 the requested geometry is on screen or not, and if some is not
2691 then the request is clamped to geometry that is on the screen.
2693 Changed 'pixbuf' to 'art_pixbuf' in core function.
2695 1999-10-08 Michael Fulbright <drmike@redhat.com>
2697 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

2700 if no filename given to test program.
2702 1999-10-07 Cody Russell <bratsche@dfw.net>
2703 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
2704 them, but I wrote them).
2706 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
2709 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
2710 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

2721 (gdk_pixbuf_scale): use gdk_pixbuf_new + return a new scaled image.
2723 * src/gdk-pixbuf.h (struct _GdkPixBuf): Re-organise struct, + add
2724 GdkPixBufUnrefFunc + gdk_pixbuf_new.
2726 * src/io-jpeg.c (image_load): clean to use gdk_pixbuf_new.
2728 * src/io-xpm.c (_pixbuf_create_from_xpm): ditto.
2730 * src/io-tiff.c (image_load): ditto + fix leak
2732 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
2733 crashes this module ( add warning :-)
2735 * src/io-bmp.c (image_load): ditto.
2737 * src/io-gif.c (image_load): ditto.
2739 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
2741 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
2742 it doesn't crash scaling with alpha.
2744 1999-09-17 Federico Mena Quintero <federico@redhat.com>
2746 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
2748 * src/io-gif.c (image_load): Likewise.
2750 * src/io-jpeg.c (image_load): Likewise.
2752 * src/io-png.c (image_load): Likewise.
2754 * src/io-tiff.c (image_load): Likewise.
2756 * src/io-xpm.c (_pixbuf_create_from_xpm): Likewise.
2758 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_image): Added an assertion
2759 for the ref_count to be != 0.
2761 * src/gdk-pixbuf.c (gdk_pixbuf_ref): Be more paranoid with sanity
2763 (gdk_pixbuf_unref): Fix incorrect sanity check and comparison.
2765 1999-08-09 Federico Mena Quintero <federico@nuclecu.unam.mx>
2767 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
2768 to unallocated memory (row_ptr), and fixed its type as well. Take
2769 into account the ArtPixbuf's rowstride when assigning the row
2772 * src/gdk-pixbuf.c: Fixup includes.
2774 * src/gdk-pixbuf-io.c: Likewise.
2776 Sat Jul 31 19:19:47 CEST 1999
2778 * src/gdk-pixbuf-io.c:
2779 * src/io-png.c: Fixed two obvious C syntax bugs
2781 1999-07-29 Mark Crichton <crichton@gimp.org>
2783 * src/io-png.c (image_save): Added PNG saving function
2785 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
2786 image_save(GdkPixBuf *p, FILE *f, ...)
2789 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
2791 * src/Makefile.am (*_LIB): Only build the relevant loaders which
2792 require extra libraries if we actually have those libraries.
2794 1999-07-23 Richard Hestilow <hestgray@ionet.net>
2796 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
2797 * gdk_pixbufConf.sh.in: Added for gnome-config
2799 * configure.in: Modified to generate gdk_pixbufConf.sh
2801 1999-07-20 Mark Crichton <crichton@gimp.org>
2803 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
2804 calculation needs to be done.
2806 1999-07-18 Larry Ewing <lewing@gimp.org>
2811 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
2812 error cases but one or two in the common case. There are probably
2813 a few small ones left.
2815 1999-07-18 Mark Crichton <crichton@gimp.org>
2817 * configure.in: removed version.h.
2819 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
2822 1999-07-17 Mark Crichton <crichton@gimp.org>
2824 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
2825 (gdk_pixbuf_rotate): Added pixbuf rotation code.
2826 (gdk_pixbuf_scale): Changed // comments to /* */
2828 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
2831 1999-07-16 Larry Ewing <lewing@gimp.org>
2833 * src/testpixbuf.c (expose_func): reverted the expose everything
2834 changes, I'm not sure why these went in.
2835 (config_func): bring this up to date with the new pixbuf_scale
2838 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
2839 loading code so that poeple can diagnose problems better.
2841 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
2842 no longer allocates a new pixbuf, which make things nicer for the
2843 rest of the code. Unfortunately there is still a problem with
2844 scaling rgba images.
2846 1999-07-16 Mark Crichton <crichton@gimp.org>
2848 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
2849 calls gdk_pixbuf_scale. However, something is not working.
2850 N.B.: current pixmap is now stored in user_data with a key of
2853 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
2854 Something is still borked, however.
2856 1999-07-15 Larry Ewing <lewing@gimp.org>
2858 * src/io-jpeg.c (image_load): add raph@gimp.org's fix to the jpeg
2861 * src/testpixbuf.c (main): fix up the file routines a little so
2862 that you can load multiple files given the file names
2864 1999-07-14 Larry Ewing <lewing@gimp.org>
2866 * src/testpixbuf.c (expose_func): added an almost proper expose
2867 handler for testpixbuf
2869 1999-07-13 Mark Crichton <crichton@gimp.org>
2871 * configure.in: Fixed GIF check. Replaced " with '
2872 * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale
2874 1999-07-13 Mark Crichton <crichton@gimp.org>
2876 * configure.in: I am a bonehead. Added gif-lib check.
