194 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
195 Keep this logic in sync with gdk_pixbuf_new_from_file(). (Based

218 an image from a file either via module->load or incrementally.
219 (prepared_notify): ModulePreparedNotifyFunc for generic_image_load.
220 (gdk_pixbuf_new_from_file): Use generic_image_load.
221 * io-bmp.c, io-ico.c, io-ras.c, io-wbmp.c: Remove trivial
222 implementations of module->load. (#71266)
224 * io-ico.c (DecodeHeader): Correct computation of image height.
225 (OneLine): Correct update notification.
227 Load-at-size functionality (#53726):
229 * gdk-pixbuf-io.h (ModuleSizeFunc): New.
230 (_GdkPixbufModule): Prepend a ModuleSizeFunc to the
231 begin_load arguments. Adjust all modules.
232 * gdk-pixbuf-loader.c (struct GdkPixbufLoaderPrivate): Add
233 fields width, height, size_fixed, need_scale.
234 (gdk_pixbuf_loader_class_init): Add size_prepared signal.
235 (gdk_pixbuf_loader_set_size): New function.
236 (gdk_pixbuf_loader_size_func): ModuleSizeFunc which gets
237 passed to the module, emits size_prepared.
238 (gdk_pixbuf_loader_prepare): Call gdk_pixbuf_loader_size_func
239 if necessary, only emit area_prepared if no separate scaling
241 (gdk_pixbuf_loader_update): Only emit area_updated if no
242 separate scaling is required.
243 (gdk_pixbuf_loader_load_module): Add size_func as first argument.
244 (gdk_pixbuf_loader_close): If necessary scale the image
245 to the desired size and emit area_prepared and area_updated.

247 size_prepared signal.
248 (gdk_pixbuf_loader_set_size) New API.
249 * gdk-pixbuf-marshal.list: Add VOID:INT,INT.
250 * io-jpeg.c: User cinfo->output_width/height instead of
251 cinfo->image_width/height throughout when adressing the pixbuf.
252 (gdk_pixbuf__jpeg_image_load_increment): Call size_func, and
253 find the nearest possible output size which libjpeg can produce
254 that is still larger than the desired size.
256 2002-07-06 Matthias Clasen <maclas@gmx.de>
258 * io-tiff.c (tiff_set_error): Handle global_error == NULL
260 (tiff_image_parse): Don't trust TIFFRGBAImageBegin to set

265 2002-07-02 Matthias Clasen <maclas@gmx.de>
267 Miscellaneous bmp loader fixes (#85448, #86286, #86287):
269 * io-bmp.c (grow_buffer): New function to avoid crashes
270 on unchecked reallocs.
271 (DecodeHeader, DecodeColormap, decode_bitmasks,
272 DoCompressed): Use grow_buffer instead of g_realloc
273 throughout. Change signatures where necessary to pass the
275 (OneLine16): Fix loading of 16bpp BI_RGB bmps.
276 (DoCompressed): Rewritten to properly support BI_RLE4 and
279 Support for compressed ras images (#84994):
281 * io-ras.c (RAS2State): Error on unsupported ras variations.
282 (OneLine8): Fix colormap indexing.
283 (OneLine): Call updated_func with proper region.
284 (DoCompressed): New function, handles compressed ras data.
285 (gdk_pixbuf__ras_image_load_increment): Handle compressed ras
288 Better colorspace support for the jpeg loader (#61211):
290 * io-jpeg.c (convert_cmyk_to_rgb): New function.
291 (gdk_pixbuf__jpeg_image_load,
292 gdk_pixbuf__jpeg_image_load_increment): Allocate a pixbuf with
293 alpha for 4-channel jpegs and call convert_cmyk_to_rgb for these.
295 All of this needs to be merged to GNOME 1.4 gdk-pixbuf.
297 2002-06-28 Sven Neumann <sven@gimp.org>
299 * gdk-pixbuf-csource.c (print_blurb): converted a Tab to spaces.
301 Thu Jun 13 18:11:11 2002 Owen Taylor <otaylor@redhat.com>
303 * pixops/pixops.c: Fix problem where when no alpha was
304 involved, we scaled rather than composited, but then
305 went ahead and composited anyways. (#76958, Patch
306 from Matthias Clasen). Needs to be merged to GNOME
309 2002-06-13 Matthias Clasen <maclas@gmx.de>
311 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
312 incrementally display incrementally loaded progressive jpegs.
314 2002-06-07 Federico Mena Quintero <federico@ximian.com>
317 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
318 starting at a specific memory location. We do this instead of
319 GINT32_FROM_LE() as the latter is simply dereferences a cast,
320 which doesn't work on platforms with alignment requirements.
323 2002-06-01 Matthias Clasen <maclas@gmx.de>
325 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
326 with a C comment - those seem to be not uncommon, e.g. the Gimp
327 produces them. (#82706)
329 * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
331 (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.
333 2002-05-22 Tor Lillqvist <tml@iki.fi>
335 * gdk-pixbuf-io.c (get_libdir): Use GTK_BINARY_VERSION (and not
336 GTK_VERSION) in the path to the loaders on Win32, too.
338 * Makefile.am: Pass GTK_BINARY_VERSION.
340 2002-05-22 Federico Mena Quintero <federico@ximian.com>
342 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
343 account!!! Fixes #82515.
345 [This bug is not present in the GNOME 1.4 branch as its XPM loader
346 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
347 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
349 [IMPORTANT: The comment above is to make my life easier when
350 merging stuff across branches. If you make changes to gdk-pixbuf
351 in either branch, please include a comment in the ChangeLog that
352 indicates whether this should be merged into the other branch.
355 2002-05-18 Matthias Clasen <maclas@gmx.de>

370 2002-05-07 Michael Natterer <mitch@gimp.org>
372 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
373 conditionally like the dynamic ones so --without-lib<foo> is
374 honored when building with --disable-modules. (#66867)
376 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
378 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to
380 * test-loaders.c, test-images.h: remove
382 2002-04-24 Matthias Clasen <maclas@gmx.de>
384 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
385 restriction from the description of png tEXt parameters.
387 * io-png.c (png_text_to_pixbuf_option):
388 (gdk_pixbuf__png_image_save): If libpng supports it,
389 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
391 2002-04-11 Matthias Clasen <maclas@gmx.de>
393 More fixes for #77807:
395 * io-tga.c (get_contiguous_pixbuf): Helper function to create
396 a pixbuf with a contiguous pixel array while being careful about
399 * io-tga.c (fill_in_context, get_image_pseudocolor,
400 get_image_truecolor, get_image_grayscale): Use
401 get_contiguous_pixbuf instead of manually allocating image
404 * io-xpm.c (pixbuf_create_from_xpm):
405 * io-pnm.c (gdk_pixbuf__pnm_image_load):
406 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
407 instead of manually allocating image storage.
409 2002-04-09 Matthias Clasen <maclas@gmx.de>
411 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
412 priv->image_module->module_name instead of image_type which may
415 2002-04-06 Matthias Clasen <maclas@gmx.de>
417 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
418 gdk_pixbuf_new instead of manually allocating image storage. This
419 gives us a good rowstride and overflow checks. (#77807)
421 2002-04-05 Matthias Clasen <maclas@gmx.de>
423 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
424 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable
425 put functions instead of TIFFRGBAImage. And check image dimensions

430 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_type): Fix a doc typo.
432 2002-03-29 Matthias Clasen <maclas@gmx.de>
434 * io-png.c (png_simple_error_callback): libpng error handlers must
435 not return to their callers, thus longjmp out. This prevents
436 annoying stderr output from the default error handler.
438 2002-03-27 Matthias Clasen <maclas@gmx.de>
440 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
442 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
443 end_info. Also call png_read_end to check proper ending of the png
444 file and catch text chunks after the image data.
446 2002-03-27 Matthias Clasen <maclas@gmx.de>
448 * io-png.c (gdk_pixbuf__png_image_load,
449 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
450 instead of system malloc.
452 2002-03-26 Matthias Clasen <maclas@gmx.de>
454 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
456 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
457 context->buf on error.
459 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
460 stop_load even for short images to prevent memleaks.
462 2002-03-25 Matthias Clasen <maclas@gmx.de>
464 * io-png.c (setup_png_transformations): Changed signature to
465 return success and set a GError parameter, adjusted all callers.
466 Also work around a possible FPE in libpng and always check that
467 the new info is sane.
469 2002-03-23 Matthias Clasen <maclas@gmx.de>
471 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
472 context->updated_func is NULL during a nonincremental load.
473 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
475 2002-03-18 Matthias Clasen <maclas@gmx.de>
477 * io-tga.c: Fix assumptions on rowstride by manually allocating a
478 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
479 Support grayscale + alpha (which can be written, but not read (!)
482 2002-03-15 Matthias Clasen <maclas@gmx.de>
484 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
486 2002-03-13 Matthias Clasen <maclas@gmx.de>
488 * test-images.h: Add valid_ras_test and invalid_bmp_1.
490 * test-loaders.c (main): Add random tests for ras and pnm and an
491 invalid bmp which was a crasher until my 2002-03-12 commit.
493 * io-pnm.c (gdk_pixbuf__pnm_image_load_increment): Don't unref the
496 * io-ras.c: Handle some errors.
498 2002-03-12 Sven Neumann <sven@gimp.org>
500 * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
501 calling memcpy(). Simpler and potentially faster. (#70332)
503 2002-03-12 Matthias Clasen <maclas@gmx.de>
505 * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
506 which could actually be reached by a proper error status return.
508 2002-03-05 Matthias Clasen <maclas@gmx.de>
510 * test-loaders.c, test-images.h: More random tests.
512 * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.
514 Tue Mar 5 10:39:03 2002 Owen Taylor <otaylor@redhat.com>
516 * Makefile.am (loaderdir): Put the modules into the
517 GTK_BINARY_VERSION directory for consistency with
518 immodules and theme engines.
520 Sat Mar 2 22:11:10 2002 Owen Taylor <otaylor@redhat.com>
522 * gdk-pixbuf-io.c (_gdk_pixbuf_load_module): If we
523 can't load the module using the g_module_build_path()
524 filename, try loading it as a .la file.
526 * test-loaders.c: Look for modules in current directory
527 rather than .libs, so we find the right .la files.
529 * test-loaders.c: Back out some accidental commits.
531 Sat Mar 2 21:28:03 2002 Owen Taylor <otaylor@redhat.com>
533 * gdk-pixbuf.c (gdk_pixbuf_new): Bullet-proof against integer
536 2002-03-03 Tor Lillqvist <tml@iki.fi>
538 * gtk-pixbuf.rc.in: Remove.
540 * gdk_pixbuf.rc.in: Name like this instead (wrong name used by

896 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
897 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't

959 - four valid ppm's, eight invalid (matthiasc@poet.de)
960 - one invalid xpm (matthiasc@poet.de)
961 - one valid tga, one invalid (sandmann@daimi.au.dk)
962 - one invalid tiff (sandmann@daimi.au.dk
964 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
966 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
967 fail - detect it when it happens

975 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
977 * Makefile.am: don't used BUILT_SOURCES to build marshal
978 files, as in conjunction with stamp files, this can
979 lead to endless rebuilding loops.

983 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1

1024 * pixops/pixops.c: applied some simple but effective optimizations
1025 to pixops_composite_nearest() and pixops_composite_color_nearest().
1027 2001-08-07 Sven Neumann <sven@gimp.org>
1029 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
1030 function, so that's what I did.
1032 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
1034 * gdk-pixdata.c: Fix a typo.
1036 2001-07-30 Hans Breuer <hans@breuer.org>

1083 * gdk-pixdata.c: <string.h>
1085 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
1086 also leaking memory here from g_strdup_printf?)
1088 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
1090 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
1092 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
1093 instead from gdk_pixbuf_new_from_inline().
1095 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
1096 installed API for applications that need to serialize/deserialize
1097 on their own (gimp, BEAST).
1099 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
1100 program that can dump images in CSource format and Pixbuf
1101 stream format. supports RLE encoding, MACRO formatting etc...
1104 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
1106 * Makefile.am: Actually update timestamps, so rules don't
1109 2001-06-11 Havoc Pennington <hp@redhat.com>
1111 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
1112 already includes top_builddir
1114 2001-06-08 Havoc Pennington <hp@redhat.com>
1116 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
1117 bogus g_return_if_fail
1119 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
1120 likely timeout resolution, set it to an arbitrarily-chosen short
1122 Fixes bug #55953 from warmenhoven@yahoo.com
1124 2001-06-07 Havoc Pennington <hp@redhat.com>
1126 * Makefile.am: use Owen's new way of doing stampfiles/generated
1129 2001-06-07 Havoc Pennington <hp@redhat.com>
1131 * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path
1133 2001-06-05 Havoc Pennington <hp@redhat.com>
1135 * test-loaders.c (main): use putenv not setenv, reported by
1138 2001-05-08 Havoc Pennington <hp@redhat.com>
1140 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1141 and fix behavior to still subst color if the original image
1144 2001-06-04 Havoc Pennington <hp@redhat.com>
1146 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1149 2001-06-01 Havoc Pennington <hp@redhat.com>
1151 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1152 Makes things a bit more robust, and adds test-loaders.c
1153 which is good for finding further robustness bugs to fix.
1155 * io-tiff.c: Try to work around libtiff suckiness a bit;
1156 put a giant thread lock on the whole loader,
1157 paranoically check both whether error handlers were called and
1158 also whether functions return false. Handle case where width or
1159 height is 0. Various cleanups.
1161 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1163 (png_error_callback): apparently libpng expects you to longjmp out
1166 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1167 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1169 (gif_get_lzw): check for out-of-memory
1170 (gif_prepare_lzw): catch/report an error
1171 (new_context): use try_malloc, since GifContext is nearly 70K
1172 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1173 so we don't crash later.
1175 * Makefile.am: Add test-loaders
1177 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1180 2001-05-29 Darin Adler <darin@eazel.com>
1182 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1184 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1186 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1187 fix up bmp decoder to:
1188 - adds 16 bpp bmp support (bug #53884)
1189 - adds OS/2 1.x format bmp support (bug #54964)
1190 - adds 4 bpp RLE compressed bmp support
1191 - adds 1 bpp colormap support
1192 - fixes negative height (top down) bmp support
1194 2001-05-25 Hans Breuer <hans@breuer.org>
1196 * gdk_pixbuf.def : reflect Havoc's recent api change
1198 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1200 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1201 excess $(GLIB_LIBS).
1203 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1205 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1207 2001-05-04 Havoc Pennington <hp@redhat.com>
1209 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1210 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1213 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1214 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1215 confusion of using "src" instead of "p".
1216 (pixops_composite_color_nearest): Use a more accurate (and
1217 correct, to begin with) compositing method. This cures checks
1218 showing through on images with no alpha.
1220 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1223 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1225 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1226 area_updated signal to use signed ints. Removed animation-related
1229 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1232 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1233 all the pesky details. Remove old frame-based API. Make
1234 GdkPixbufAnimation an abstract base class, derived by the loaders.
1236 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1238 * Makefile.am (LDADDS): Add $(MATH_LIB).
1240 2001-04-18 Havoc Pennington <hp@redhat.com>
1242 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1245 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1247 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1248 so we don't try to get <gtk/gtkobject.h> from standard search
1251 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1252 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1253 take gdk-pixbuf-marshal.h out of _la sources.
1255 2001-03-19 Tor Lillqvist <tml@iki.fi>
1257 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1259 * gdk_pixbuf.def: Update.
1261 * pixbufloader_*.def: Just export the fill_vtable functions now.
1263 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1265 * make-inline-pixbuf.c (main): Added logic to remove output when
1268 2001-03-14 Havoc Pennington <hp@redhat.com>
1270 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1271 from gdk-pixbuf-marshal.h, fixes parallel makes.
1273 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1275 * test-gdk-pixbuf.c: fixed includes.
1277 2001-02-18 Havoc Pennington <hp@pobox.com>
1279 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1280 (gdk_pixbuf_get_named_module): prepend underscore
1281 (gdk_pixbuf_get_module): prepend underscore
1283 2001-02-19 Havoc Pennington <hp@redhat.com>
1285 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1287 2001-02-17 Havoc Pennington <hp@pobox.com>
1289 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1291 2001-02-07 Alexander Larsson <alexl@redhat.com>
1293 * io-xpm.c (free_buffer):
1294 Use g_free, since the buffer is allocated with g_try_alloc().
1296 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1298 * gdk-pixbuf-data.c: Fixes a minor typo.
1300 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1302 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1303 we finally need the gobject->gruntime rename.
1305 * *.c: scratched calls to g_type_init(), there's simply no point in
1306 doing that, use gtk_init().
1308 2001-02-01 Havoc Pennington <hp@pobox.com>
1310 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1311 in struct to "priv" for C++
1313 2001-01-31 Havoc Pennington <hp@pobox.com>
1315 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1317 2001-01-26 Havoc Pennington <hp@redhat.com>
1319 * gdk-pixbuf-io.c (mname): fix included modules case.
1321 2001-01-22 Havoc Pennington <hp@redhat.com>
1323 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1324 from gdk_pixbuf_load_module
1326 2001-01-22 Havoc Pennington <hp@redhat.com>
1328 * Makefile.am: Add built marshaller files to support
1329 GdkPixbufLoader signals
1331 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1332 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1333 module location, rather than acting as a fallback, because we are
1334 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1336 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1338 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1339 from gtk, and add error to close(), because stop_load may do
1340 parsing of the image.
1342 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1344 * io-*.c: make individual operations static, and add fill_vtable
1345 functions which are exported. Fix the collection of type warnings
1346 that surfaced, including a number of functions that didn't
1347 properly take a GError and some that weren't
1348 const-correct. Involved adding error handling for a few loaders.
1350 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1352 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1353 a function that fills in the GdkPixbufModule vtable, instead of
1354 looking up all the image functions individually; this means we
1355 can get type safety within modules for the loader functions.
1356 Also it means you don't have to keep the statically compiled and
1357 GModule versions in sync.
1359 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1361 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1363 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1365 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1368 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1370 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1373 2001-01-20 John Harper <jsh@eazel.com>
1375 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1376 collision between Xlib's RdBitF.c and io-tiff.c
1378 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1381 [ merged from stable gdk-pixbuf module. Untested, but it
1382 compiles, and works fine in the stable module ]
1384 2001-01-18 Tor Lillqvist <tml@iki.fi>
1386 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1387 g_win32_get_package_installation_subdirectory() function. No need
1388 to include windows.h.
1389 (gtk_win32_get_installation_directory): Remove this then.
1391 2001-01-01 Havoc Pennington <hp@redhat.com>
1393 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
1394 @LIBTOOL_EXPORT_OPTIONS@
1396 2000-12-30 Tor Lillqvist <tml@iki.fi>
1398 * gdk_pixbuf.def: Update.
1400 2000-12-16 Havoc Pennington <hp@pobox.com>
1402 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1403 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1404 (gdk_pixbuf_frame_copy): new function
1405 (gdk_pixbuf_frame_free): new function
1406 (gdk_pixbuf_frame_get_type): new function
1407 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
1409 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
1411 * Makefile.am: Add -avoid-version for all modules.
1413 2000-11-13 Havoc Pennington <hp@redhat.com>
1415 * io-png.c (png_simple_error_callback): fix error message to not
1416 say "save" since it's used for loading
1418 2000-11-11 Hans Breuer <Hans@Breuer.Org>
1420 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1421 contained image handlers (!USE_G_MODULE). Files to save should
1422 be opened in binary mode, fopen(s, "wb").
1424 * io-xpm.c : added HAVE_UNISTD_H condition
1426 2000-11-11 Tor Lillqvist <tml@iki.fi>
1428 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1430 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1431 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1432 mktemp() and open()).
1434 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1436 2000-11-01 Havoc Pennington <hp@pobox.com>
1438 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1439 a pixbuf pointing to a subregion of another pixbuf.
1441 2000-10-16 Tor Lillqvist <tml@iki.fi>
1443 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1445 2000-10-16 Havoc Pennington <hp@redhat.com>
1447 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1448 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1449 add error reporting here also

1464 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1467 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1468 a G_FILE_ERROR if we fail to write or close the file.
1470 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1471 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1472 the GError naming rules. Add GError** to load functions.
1474 2000-10-06 Havoc Pennington <hp@redhat.com>
1476 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1478 2000-10-06 Havoc Pennington <hp@redhat.com>

1538 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
1539 xpm at least supports the progressive interface like the one in

1643 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1645 * makefile.mingw.in: List loaders alphabetically. Add the wbmp

1648 2000-07-31 Elliot Lee <sopwith@redhat.com>
1649 * io-wbmp.c: Some bug fixes - now tested to work.
1651 2000-07-27 Elliot Lee <sopwith@redhat.com>
1653 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1654 gdk_pixbuf_get_named_module() function to facilitate above change
1655 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1656 Implement loader for WBMP format.
1657 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1659 2000-07-23 Tor Lillqvist <tml@iki.fi>
1664 * pixops/makefile.mingw.in
1665 * pixbuf_*.def: New files.
1668 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1670 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1671 New function, to get the GTK+ installation directory from
1672 the Windows Registry, where the installation program
1673 for whatever software includes GTK+ has stored it.
1675 Used to avoid having hardcoding the directory where to look for
1676 loaders. This function is needed by gtk, too, so it should
1677 really be just in one place. Maybe a small static library
1678 one level up from here?
1680 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1681 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1682 Open file in binary mode. This *is* standard C. (No-op on Unix,
1685 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1687 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1688 mktemp() and open().
1689 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1691 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1692 pseudo-op. Conditionalise on __MINGW32__, but probably
1693 should conditionalise on Gas version instead? Or could we
1694 do without .type on all systems?
1696 * pixops/timescale.c: Use g_get_current_time()
1697 instead of gettimeofday().
1699 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1701 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1703 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1705 * gdk-pixbuf.c: Add <string.h> include.
1707 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1709 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1710 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1711 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1712 use g_object_new() instead of g_type_create_instance() which
1713 is a private function for fundamental type implementations.
1715 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1717 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1718 soname scheme for gdk-pixbuf.
1720 2000-06-21 Havoc Pennington <hp@pobox.com>
1722 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1723 (i.e. derivation is not allowed, and there are no virtual methods
1725 (gdk_pixbuf_preinit): Call g_type_init() here.
1726 (gdk_pixbuf_init): Add a user-friendly init function, for users
1727 of standalone gdk-pixbuf
1729 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1730 way GdkPixbufAnimation was done.
1732 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1733 gdk_pixbuf_finalize() from API, since these are broken and don't
1734 make sense with new GObject stuff.
1736 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1738 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1739 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1742 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1744 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1745 so I needed something to warm my thighs. Running plain infinite
1746 loops on your laptop to make it hot is not very much fun. A demo
1747 of the gdk-pixbuf scaling functions is way better, and looks
1750 * configure.in (AC_OUTPUT): Added the demo Makefile.
1752 * Makefile.am (SUBDIRS): Added the demo directory.
1754 2000-06-09 Larry Ewing <lewing@helixcode.com>
1756 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1757 setjmp for the png error handler. It seems setting the error
1758 handling functions does not avoid the jump, and so not calling
1759 setjmp was causing the incremental loader to jump into lala land.
1760 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1761 not sure this one is actually required but the docs say it must be
1762 set for every call to a png_* function.
1763 Also changed the comment to reflect the fact that setting the
1764 error handlers does _not_ avoid the longjmp.
1766 2000-06-06 Larry Ewing <lewing@helixcode.com>
1768 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1769 take frame offest into account when trying to calculate the
1770 animation bbox. Also set the width to the width not the height.
1771 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1772 calculate bbox because now we finally have all the offset
1773 information for each frame.
1775 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1777 * configure.in: add some gtk parameters to the
1778 GDK_PIXBUF_LIBÃ�²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1779 fight in my crusade for strange prefix compile...
1781 2000-05-30 Not Zed <NotZed@HelixCode.com>
1783 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
1784 Initialise the error handler exit routine to our own. Note this
1785 means that every function that accesses the jpeg lib on this
1786 object MUST do a setjmp.
1787 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
1788 lib for handling fatal error.
1789 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
1790 your applications dont quit if there's a jpeg error!
1792 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
1794 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
1795 from Frank de Lange <frank@unternet.org>.
1797 2000-05-09 Darin Adler <darin@eazel.com>
1799 * gdk-pixbuf/test-gdk-pixbuf.c:
1800 Fixed includes to get rid of accidental GNOME dependency.
1802 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
1803 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
1805 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
1807 * configure.in: Bumped version number to 0.8.0.
1809 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
1810 file was not being distributed.
1812 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
1814 2000-05-09 Darin Adler <darin@eazel.com>
1816 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
1817 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
1818 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
1819 formats to 32-bit formats to re-use the high bits of the color values
1820 so that white maps to full white.
1822 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
1824 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
1825 detailed information about the structure and algorithms
1826 of pixops so people can fix it instead of breaking it.
1828 2000-05-04 Darin Adler <darin@eazel.com>
1830 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
1831 (composite_pixel), (composite_line):
1832 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
1833 Now that Owen explained the algorithm, I think I implemented it
1834 right for the cases where the destination pixbuf is not opaque.
1835 The test does seem to confirm it.
1837 2000-05-04 Darin Adler <darin@eazel.com>
1839 * gdk-pixbuf/.cvsignore:
1840 * gdk-pixbuf/Makefile.am:
1841 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
1842 (load_pixel), (simple_composite_test_one),
1843 (simple_composite_test_one_type), (simple_composite_test), (main):
1844 Added some tests of composite to highlight problems in the old
1845 implementation. These tests run without any user interaction.
1846 Just do "make check".
1848 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
1849 (composite_pixel), (composite_line): Fix composite to do a textbook
1850 "A over B" composite. This was clearly the intent, and it was easy
1851 to fix the code to do it. (Note to those that read my earlier tries
1852 at a patch; this version fixes typos that were present in all
1853 my patch attempts. I checked the final version by adding more tests.)
1855 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
1857 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
1858 offset y coordinate accordining to render_y0.
1860 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
1863 2000-04-22 James Henstridge <james@daa.com.au>
1865 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
1866 package to the devel package. The only file installed in bin is
1867 gdk-pixbuf-config, which belongs in -devel. This should allow having
1868 multiple versions of the main gdk-pixbuf package installed.
1870 2000-04-17 Karl Eichwalder <ke@suse.de>
1872 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
1873 Reported by Jens Finke.
1875 2000-04-14 Tomasz KÃ�³opczko <kloczek@pld.org.pl>
1877 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
1878 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
1880 2000-04-13 James Henstridge <james@daa.com.au>
1882 * configure.in: when performing the configure check to see if
1883 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
1884 rather than the other way round. Also, call AC_MSG_RESULT in the
1885 even that dynamic modules were not supported.
1887 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
1889 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
1890 hook to the last unref operation.
1892 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
1893 function to set the last unref handler for a pixbuf.
1894 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
1895 It calls the pixbuf's destroy notification function and frees the
1896 GdkPixbuf structure itself.
1897 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
1900 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
1901 for the last unref handler and its user data.
1903 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
1904 g_new0() to allocate the pixbuf.
1906 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
1907 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
1908 was not specifying the `frame' argument.
1910 * gdk-pixbuf/gdk-pixbuf-animation.c
1911 (gdk_pixbuf_animation_get_width): Fixed docstring.
1912 (gdk_pixbuf_animation_get_height): Likewise.
1913 (gdk_pixbuf_animation_get_num_frames): Likewise.
1914 (gdk_pixbuf_animation_get_frames): Likewise.
1916 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1919 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1921 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1923 * doc/tmpl/refcounting.sgml: Updated with the information about
1924 the last unref handler.
1926 * doc/tmpl/*.sgml: Markup tweaks.
1928 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1929 update the libtool version number for libgnomecanvaspixbuf as
1931 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
1932 as well, or the old ones won't work with the new stuff. Also,
1933 renamed the modules as follows.
1935 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
1936 modules are called "libpixbufloader-<format>.so" instead of
1937 "libpixbuf-<format>.so". They needed renaming so that the new
1938 loaders won't overwrite the old ones; even with the versioning
1939 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
1942 2000-04-12 Paolo Molaro <lupus@debian.org>
1944 * .cvsignore, src/.cvsignore: shut up cvs.
1946 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
1948 Most of this patch is based on a patch by Havoc Pennington
1949 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
1950 remove the libart dependency.
1952 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
1953 (GdkColorspace): New enum that for now only contains
1955 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
1956 notification function.
1957 (GdkInterpType): New num with interpolation types.
1959 * *.[ch]: Replace the libart stuff with our own stuff.
1961 * pixops/*.[ch]: Likewise.
1963 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
1964 declarations of the GdkPixbuf structures.
1966 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
1968 (gdk_pixbuf_get_format): Constify.
1969 (gdk_pixbuf_get_n_channels): Constify.
1970 (gdk_pixbuf_get_has_alpha): Constify.
1971 (gdk_pixbuf_get_bits_per_sample): Constify.

1973 (gdk_pixbuf_get_width): Constify.
1974 (gdk_pixbuf_get_height): Constify.
1975 (gdk_pixbuf_get_rowstride): Constify.
1977 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
1980 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
1981 bits_per_sample argument; currently only 8 bits per sample are
1984 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
1986 (gdk_pixbuf_frame_get_x_offset): New accessor.
1987 (gdk_pixbuf_frame_get_y_offset): New accessor.
1988 (gdk_pixbuf_frame_get_delay_time): New accessor.
1989 (gdk_pixbuf_frame_get_action): New accessor.
1991 * gdk-pixbuf/gdk-pixbuf-render.c
1992 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
1993 mask rectangle for pixbufs without an alpha channel, set the
1994 *mask_return to NULL.
1996 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
1998 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
2000 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
2001 preconditions. Maybe we should also check for the colorspace,
2002 bits per pixel, and such.
2003 (gdk_pixbuf_composite): Likewise.
2004 (gdk_pixbuf_composite_color): Likewise.
2005 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
2006 cannot allocate the new pixbuf.
2007 (gdk_pixbuf_composite_color_simple): Likewise.
2009 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
2010 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
2013 * gdk-pixbuf/io-bmp.c: Fix includes.
2015 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
2020 * configure.in: Removed checks for libart.
2022 * gdk-pixbuf/Makefile.am: Removed references to libart.
2023 (noinst_HEADERS): Added gdk-pixbuf-private.h.
2025 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
2026 the version number of the libtool library to indicate that this
2027 definitely is not compatible with the old usage. I know you love
2030 * configure.in: Bumped version number to 0.7.0.
2034 * gdk-pixbuf-config.in (--libs): We no longer require libart.
2036 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
2038 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
2040 2000-04-06 Jonathan Blandford <jrb@redhat.com>
2042 * gdk-pixbuf/testanimation.c (main): add more info to the
2043 testanimation frames.
2045 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
2047 * gdk-pixbuf/gdk-pixbuf-animation.c
2048 (gdk_pixbuf_animation_get_width): New accessor function.
2049 (gdk_pixbuf_animation_get_height): New accessor function.
2050 (gdk_pixbuf_animation_get_num_frames): New accessor function.
2051 (gdk_pixbuf_animation_get_frames): New accessor function.
2053 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
2055 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
2056 is private information, and the art_pixbuf will go away soon.
2058 2000-03-31 Mark Crichton <crichton@gimp.org>
2060 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
2061 and gdk_pixbuf_get_artpixbuf accessor functions.
2063 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
2065 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
2066 gboolean instead of int.
2068 2000-03-29 Radek Doulik <rodo@helixcode.com>
2070 * gdk-pixbuf/gdk-pixbuf-animation.c
2071 (gdk_pixbuf_animation_new_from_file): same as below
2073 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
2074 height in GdkPixbufAnimation
2076 2000-03-28 Radek Doulik <rodo@helixcode.com>
2078 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
2079 context->frame_done_func and context->anim_done_func to make
2080 progressive animation loading work
2082 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
2083 added priv->pixbuf = NULL as pixbuf is now in frame (and to make
2084 gdk_pixbuf_loader_prepare happy)
2085 (gdk_pixbuf_loader_frame_done): update animation bbox
2087 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
2090 2000-03-27 Radek Doulik <rodo@helixcode.com>
2092 * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
2093 instead of width and height
2095 2000-03-27 Owen Taylor <otaylor@redhat.com>
2097 * gdk-pixbuf/pixops/pixops.c: Fix problem with
2098 precendence of >> and & which was keeping composite_color
2099 from working with non-gray images.
2101 2000-03-08 Jonathan Blandford <jrb@redhat.com>
2103 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.
2104 (gdk_pixbuf__gif_image_load_animation): free the context.
2106 2000-03-06 Arjan van de Ven <arjan@fenrus.demon.nl>
2108 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
2109 mis-interpretation of the Microsoft documentation. Now
2110 it can load .BMP files that are not generated by The Gimp
2113 2000-03-01 Mark Crichton <crichton@gimp.org>
2115 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
2116 fix the last auto* build bug (where we have libart, but no
2119 * gdk-pixbuf/Makefile.am: Same.
2121 2000-02-28 Matt Wilson <msw@redhat.com>
2123 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
2124 s/unsigned short/guint16/g, s/unsigned char/guint8/g
2126 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
2128 * README: We don't require libgif/ungif nor libXpm.
2130 * NEWS: This was outdated, so updated it.
2132 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
2134 * gdk-pixbuf.m4: Use the correct name for
2135 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing
2138 2000-02-21 Federico Mena Quintero <federico@helixcode.com>
2140 * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0.
2142 * doc/compiling.sgml: New appendix documenting the gdk-pixbuf
2143 library's particular options to configure.in.
2145 * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an
2148 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
2150 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
2151 Fixed typo in prototype name.
2153 * configure.in: Changed duplicated AC_MSG_CHECKING message to
2154 something more meaningful; now it is "checking whether dynamic
2157 * gdk-pixbuf/pixops/Makefile.am (noinst_PROGRAMS): Do not install

2530 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
2531 animation functions here.
2532 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
2533 animation if the loader does not support multiframe loading and

2546 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
2549 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
2550 with a reference count of 1.
2552 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
2553 gdk-pixbuf-animation.c.
2555 * doc/tmpl/animation.sgml: Populated. It is still missing a
2556 description of the overlay modes.

2574 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
2575 set to NULL here (specifically context->animation) was not being
2576 set to NULL. use g_new0() to alloc the struct.
2578 1999-12-20 Jonathan Blandford <jrb@redhat.com>
2580 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2581 correctly. Progressive loading needs some work, but that all
2582 needs doing from the gdk-pixbuf-loader end, not here.
2584 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2586 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2587 moved the file here. It seems natural to put this function here,
2588 as that's where the gdk_pixbuf_new_from_file function is, but it's
2589 still a little convoluted. The source files might be played with
2592 1999-12-14 Jonathan Blandford <jrb@redhat.com>
2594 * gdk-pixbuf/gdk-pixbuf-loader.c
2595 (gdk_pixbuf_loader_get_animation): Gets the animation from the

2606 * gdk-pixbuf/gnome-canvas-pixbuf.c
2607 (gnome_canvas_pixbuf_class_init): Renamed arguments to
2608 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
2609 consistency with the new canvas.
2610 (PixbufPrivate): Do the same renaming in the structure fields, for
2613 * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.

2638 Filled in body of function.
2639 (rgbconvert): Added GdkColormap parameter, and to all conversion
2641 (convert_real_slow): New function - should convert ANY visual/data
2642 format properly, but it aint fast. Used as a fallback when an
2643 optimised routine wont match.
2644 (rgbconvert): Do very specific tests on the data format to verify
2645 properly if the optimised version will do, otherwise use the
2646 fallback function for all other data formats.
2648 * gdk-pixbuf/Makefile.am: Re-enabled building of
2649 textpixbuf-drawable.
2651 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
2652 gdk_pixbuf_get_from_drawable().
2654 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
2656 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red

2663 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2664 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2665 checks and API definition. The body needs filling in and it needs
2666 to do the Right Thing(tm) for pixmaps plus the given colormap and
2667 windows and their own colormaps.
2669 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2670 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
2672 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
2674 * doc/tmpl/from-drawables.sgml: Populated.

2686 reference counting for GdkPixbuf structures.
2688 1999-12-07 Martin Baulig <martin@home-of-linux.org>
2690 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
2691 include $(GNOME_LIBS) here.
2693 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2695 Added missing "include <string.h>" to:
2696 * gdk-pixbuf/io-ras.c

2700 1999-12-06 Federico Mena Quintero <federico@redhat.com>
2702 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
2705 1999-12-05 Federico Mena Quintero <federico@redhat.com>
2707 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2708 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2709 want, send me a patch to do the conditional stuff properly.
2710 Otherwise, please read the GNOME Programming Guidelines,
2711 especially the "CVS policies" section.
2713 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
2715 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
2717 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>

2722 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
2724 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
2725 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
2727 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
2729 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
2732 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
2733 (Windows Cursor files). These are identical to .ICO files,
2734 except for the signature and 2 extra fields for the hotspot.
2736 1999-12-03 Federico Mena Quintero <federico@redhat.com>
2738 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):

2744 explain this function better.
2746 1999-12-02 Federico Mena Quintero <federico@redhat.com>
2748 Source files moved from src/ to gdk-pixbuf/, to be consistent with
2751 * doc/Makefile.am: Modified for the new source directory.

2823 1999-11-29 Owen Taylor <otaylor@redhat.com>
2825 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
2826 Keep the mask around until after we draw ... since
2827 the GC changes aren't flushed to the X server until we
2828 draw, destroying it before that may result in BadPixmap
2831 1999-11-30 Havoc Pennington <hp@pobox.com>
2833 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
2835 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
2837 1999-11-29 Federico Mena Quintero <federico@redhat.com>
2839 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
2840 should be made conditional, not blindly commented out.
2842 1999-11-29 Jonathan Blandford <jrb@redhat.com>
2844 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
2845 handle .ico files. Cool.
2847 1999-11-24 Jonathan Blandford <jrb@redhat.com>
2849 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
2852 1999-11-24 James Henstridge <james@daa.com.au>
2854 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
2855 top builddir rather than src. This still builds fine, and does not
2856 get gtk-doc into an infinite loop when trying to find all the source
2859 1999-11-23 Jonathan Blandford <jrb@redhat.com>
2861 * Removed #PRAGMA } from headers. Also, make compile if you don't
2862 have it installed, already.
2864 1999-11-22 Federico Mena Quintero <federico@redhat.com>
2866 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
2867 temporary buffer to the size of the interesction of the bounding
2868 box and the expose area, not the whole expose area. This speeds
2871 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
2872 not paint black on the mask, since we already cleared it in a
2873 single gdk_draw_rectangle() operation.
2875 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
2877 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
2879 1999-11-22 Havoc Pennington <hp@pobox.com>
2881 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
2882 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
2883 dependencies to LIBADD variables for loadable modules. Necessary
2884 for a Java dynamic loading thing to be able to figure it out.
2886 1999-11-22 Havoc Pennington <hp@pobox.com>
2888 * src/io-png.c (image_load_increment): Call the update_area
2889 callback depending on the number of rows loaded in this increment.
2891 * src/testpixbuf.c (main): slow down the progressive load demo
2893 1999-11-16 Havoc Pennington <hp@pobox.com>
2895 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
2897 1999-11-22 Jonathan Blandford <jrb@redhat.com>
2899 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
2900 for srcdir != buildir != . Beats me why; I can't figure it out.
2901 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
2903 1999-11-21 Jonathan Blandford <jrb@redhat.com>
2905 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
2906 <arjan@fenrus.demon.nl>
2908 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2910 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
2911 Rework/reorder of the code. Each case has been separated into
2912 another function; its big but it should be quick.
2913 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
2914 opaque alpha information. Not all depths/formats have been
2915 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
2917 1999-11-17 Larry Ewing <lewing@gimp.org>
2919 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2920 implement the bounds method correctly.
2921 (compute_viewport_affine): compute the affine need to fit the
2922 image within the viewport given by the args.
2923 (compute_render_affine): call compute_viewport_affine.
2925 1999-11-16 Havoc Pennington <hp@pobox.com>
2927 * src/gdk-pixbuf-drawable.h: Use includes from the current
2928 directory, not the system directory.
2930 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
2932 * src/testpixbuf-drawable.c: use includes from the current directory
2933 rather then from the system include directory as gdk-pixbuf
2934 includes are not yet installed when this is compiled.
2936 1999-11-13 Cody Russell <bratsche@dfw.net>
2937 * src/testpixbuf-drawable.c: Added a test program for drawable
2940 * src/Makefile.am: Build testpixbuf-drawable.
2942 1999-11-12 Cody Russell <bratsche@dfw.net>
2944 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.

2955 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2957 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
2960 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
2961 correctly. Patch from Arjan to do so.
2963 1999-11-10 Michael Fulbright <drmike@redhat.com>
2965 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
2968 * src/testpixbuf.c: Added final queued draw when done loading image.
2970 1999-11-10 Jonathan Blandford <jrb@redhat.com>

2986 1999-11-09 Michael Fulbright <drmike@redhat.com>
2988 * src/testpixbuf.c: Fixed it to use timeout to read from file
2989 for progressive loading. Set TBF_KBPS=n, where n is the number of
2990 kilobytes/second to simulate in downloading. n has to be an integer.
2992 * src/io-jpeg.c: Slight cosmetic cleanup.
2994 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
2995 PBM loading has a similar problem and will address tomorrow.
2997 1999-11-09 Havoc Pennington <hp@pobox.com>
2999 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
3000 gdk-pixbuf-drawable stuff.
3002 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3004 * configure.in: Bumped version number to 0.4.
3006 1999-11-09 Michael Fulbright <drmike@redhat.com>
3008 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
3009 all types of PNM files now.
3011 * src/io-jpeg.c (image_load_increment): Figured out problem with
3012 loading Progressive JPEG's progressively (say that 10 times fast).
3013 Currently for Progressive JPEG's the entire image is loaded before
3014 it is displayed. libjpeg supports a fancier mechanism which I may
3017 With these changes all JPEG formats appear to load properly for me.
3019 1999-11-08 Jonathan Blandford <jrb@redhat.com>
3021 * src/io-ras.c (image_load_increment): Final patch from Arjan.
3022 Seems to do progressive loading.
3024 1999-11-08 Michael Fulbright <drmike@redhat.com>
3026 * src/io-pnm.c image_load (): Fixed so we do not create a separate
3027 pixel buffer when reading in image - we reuse the pixel data in
3028 the GdkPixbuf structure instead.
3030 1999-11-08 Michael Fulbright <drmike@redhat.com>
3032 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
3033 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
3034 I can't seem to find a utility to convert into this format.
3035 Next is to add progressive loading support for the PNM format.
3037 1999-11-07 Federico Mena Quintero <federico@redhat.com>
3039 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation

3049 * src/io-ras.c (image_load): new file from Arjan van de Ven
3050 <arjan@fenrus.demon.nl> to begin the ras loader.
3052 1999-11-05 Federico Mena Quintero <federico@redhat.com>

3073 * src/io-jpeg.c: Prettied up code slightly.
3074 * src/io-pnm.c: Start of pnm loader (from file and progressively).
3075 Doesn't do much yet (will finish tomorrow).
3076 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.

3087 docs, explain what a dither offset is for.
3088 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3089 this function vs. gdk_pixbuf_render_to_drawable().
3091 1999-11-04 Havoc Pennington <hp@pobox.com>
3093 * configure.in: Use libart-config correctly; find gnome-config
3094 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3097 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3100 Patch untested in the inside-gnome-libs case, I need to commit
3101 then check out to the gnome-libs I'm using.

3152 bugginess in local buffering code. Handles grayscale jpegs
3155 * src/io-jpeg.c (image_load_stop): Was freeing local context

3204 1999-11-03 Michael Fulbright <drmike@redhat.com>
3206 * src/io-jpg.c (image_load_increment): Fixed code which moved
3207 buffer around as new data comes in to work properly. JPEG progressive
3208 loading should be working now except for grayscale JPEG's, which I
3209 will look into next.
3211 1999-11-03 <sopwith@redhat.com>
3212 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
3213 Also put dot printing back in.
3215 1999-11-03 <jrb@redhat.com>
3217 * src/io-gif.c (gif_get_extension): Read 'til the next empty block

3227 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
3228 for interlacing and progressive loading.

3231 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
3232 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
3234 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3236 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
3237 It's a little slow though. )-:
3239 1999-11-02 Elliot Lee <sopwith@redhat.com>
3240 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
3241 write/load_increment operations const-correct.
3243 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3245 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
3246 Implemented the ::point() method. We do a simple containment test
3247 instead of a full distance calculation since the canvas is going
3248 to change to that scheme, anyways.
3250 1999-11-02 Elliot Lee <sopwith@redhat.com>
3252 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
3253 that are read from the input file.
3255 1999-11-02 Larry Ewing <lewing@gimp.org>
3257 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
3259 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
3262 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3264 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3265 affine computation code from ::draw() to here, since it is needed
3266 by ::point() as well.
3268 1999-11-02 Elliot Lee <sopwith@redhat.com>
3270 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3271 three functions, and eliminate duplication of code from write()
3272 and close(). Also fix bug where the 128-byte header was being
3275 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3276 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3277 bounding box computation.
3279 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3281 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3282 Drawing affines seem to work. Bounding box is fubared. ::point()
3283 is not implemented. This is a work in progress.
3285 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3288 * configure.in: Sigh. We need to link in libgnomeui for the
3289 canvas stuff. This mess will disappear when gdk-pixbuf gets
3290 folded into gnome-libs.
3292 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3294 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3295 the right size, at a minimum, even if the image is squished and
3297 (ReadImage): lets get the offset right. This will let transparent
3300 1999-10-29 Michael Fulbright <drmike@redhat.com>
3302 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3303 image width was not a multiple of 4 - always use the
3304 gdk_pixbuf rowstride to increment pointers!
3306 1999-10-29 Michael Fulbright <drmike@redhat.com>
3308 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3309 Currently does not handle either progressive jpeg files (jpeg
3310 files with multiple scans at different quality settings), but
3311 I plan on adding this support soon. These are fairly rare in
3312 my experience, so it shouldn't slow people down too much.
3313 Grayscale jpegs also don't work but that should be easy to fix.
3315 1999-10-29 Michael Fulbright <drmike@redhat.com>
3317 * src/testpixbuf.c: Added title to windows so you can identify
3318 progressive and file windows.
3320 1999-10-29 Michael Fulbright <drmike@redhat.com>
3322 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3323 load the image handler when we determine the image type.
3325 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3326 previously static function load_image_handler () to
3327 a public function gdk_pixbuf_load_module (). It is needed in
3328 gdk-pixbuf-loader.c to load image handler modules. This function
3329 is different from gdk_pixbuf_get_module (), which only returns
3330 a reference to the required handler, because it actually loads
3331 the handler into memory. Both actions should possibly be combined
3332 in a convenience function since one w/o the other doesn't seem to
3335 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3337 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
3340 1999-10-28 Federico Mena Quintero <federico@redhat.com>
3342 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3343 function to render a portion of a pixbuf to a drawable. Ignores
3344 alpha information and takes in a GC.
3345 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3346 portion of a pixbuf to a drawable. It automatically creates a GC
3347 and a clipping mask for alpha pixbufs.
3349 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3351 * src/gdk-pixbuf.h: turned convenience macros into convenience
3352 functions so some error checking could be added.
3354 * src/io-tiff.c (image_load_increment): started work on the tiff
3355 non-incremental loader.
3356 (image_begin_load): Finished the incremental loader.
3358 * src/io-gif.c (image_load_increment): started work on the gif
3361 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
3363 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3365 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3366 function to threshold a pixbuf's alpha channel into a bitmap.
3368 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3369 contemplate future extensions to ArtPixBuf's formats.
3371 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3373 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3374 macros to fetch the ArtPixBuf's fields.
3376 1999-10-27 Havoc Pennington <hp@pobox.com>
3378 * src/testpixbuf.c (main): Display the progressive load
3380 * src/io-png.c (setup_png_transformations): Break transformation
3381 code into separate function
3382 (png_info_callback): Use setup_png_transformations
3384 1999-10-27 Havoc Pennington <hp@pobox.com>
3386 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3387 properly whether the XPM module has already been loaded
3388 (gdk_pixbuf_new_from_file): Check properly if loader module
3389 was already loaded (was checking if load symbol was present
3390 in order to decide whether to re-load; should check module !=
3391 NULL, then load != NULL)
3392 (image_handler_load): Check in present working directory,
3393 makes it easier to debug for now
3394 (file_formats): This array initializer was seriously on crack,
3395 was assigning a function pointer to a GModule*
3397 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
3399 1999-10-27 Havoc Pennington <hp@pobox.com>
3401 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_finalize):

3405 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3407 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
3408 GdkPixbufLoader, not a GtkObject.
3409 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
3410 (gdk_pixbuf_loader_get_type): Documented.
3411 (gdk_pixbuf_loader_class_init): Initialize the parent class
3413 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
3414 class destroy function.
3415 (gdk_pixbuf_loader_new): Documented.
3416 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3418 (gdk_pixbuf_loader_write): Use size_t for count.
3420 1999-10-27 Michael Fulbright <drmike@redhat.com>
3422 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3423 logic so we only try to close loader if it wasn't previously closed.
3425 1999-10-27 Michael Fulbright <drmike@redhat.com>
3427 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of

3454 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3456 1999-10-22 Havoc Pennington <hp@pobox.com>
3458 * src/io-xpm.c (mem_buffer): Clean up stupid
3459 increment-inside-array-dereference thing
3461 * src/testpixbuf.c: Add XPM data tests.
3463 * src/io-xpm.c: Make the XPM data buffer const, fix const
3464 correctness throughout the code.
3466 1999-10-22 Havoc Pennington <hp@pobox.com>
3468 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

3476 function, loads pixbuf from xpm data
3477 (image_handler_load): Add g_return_if_fail() to ensure the same
3478 module isn't loaded twice. Add g_module_symbol() to scan for XPM
3481 1999-10-22 Federico Mena Quintero <federico@redhat.com>
3483 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3484 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
3485 buffers; the rows can be read in directly into the main pixel
3488 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3490 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
3492 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3494 * configure.in: Bumped version number to 0.3.
3496 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
3497 version number for the library.
3499 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3501 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
3502 all memory management of the buffer is done by libart.
3504 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
3505 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
3507 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
3508 terms of the libart functions. Removed the old code.
3510 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
3511 symbols. Saving will not be implemented in GdkPixbuf.
3513 * src/io-gif.c: Removed the saving stub.
3514 (image_load): Fixed memory management to fail gracefully if we run
3515 out of memory while loading the image. Close the gif file when we
3516 are done. This still needs more error handling for the DGif
3519 * src/io-jpeg.c (image_load): Some robustness fixes.
3521 * src/io-png.c: Removed the saving stuff.
3522 (image_load): Some memory management fixes.

3532 * autogen.sh: use subautogen.sh
3534 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3536 * src/*: Reindented to use the GNOME Indentation. Renamed
3537 GdkPixBuf to GdkPixbuf, for consistency with the function names
3538 (and it is also easier to type) :-)
3540 1999-10-18 Havoc Pennington <hp@pobox.com>
3542 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
3544 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
3546 1999-10-18 Havoc Pennington <hp@pobox.com>
3548 * Makefile.am (SUBDIRS): Remove "macros"
3550 * configure.in: Don't use GNOME_INIT, handle case where we are
3551 inside gnome-libs. AM_PATH_GTK for the GIF test
3553 * src/Makefile.am: Change flags to work without libgnomeui,
3554 comment out testpixbuf for now
3556 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3558 * configure.in: Use $GTK_LIBS as the extra libs when checking for
3559 libgif/libungif, as they need the X libraries. Fixes bug #2472.
3561 1999-10-10 Cody Russell <bratsche@dfw.net>
3562 * src/gdk-pixbuf-drawable.c: core function now determines whether
3563 the requested geometry is on screen or not, and if some is not
3564 then the request is clamped to geometry that is on the screen.
3566 Changed 'pixbuf' to 'art_pixbuf' in core function.
3568 1999-10-08 Michael Fulbright <drmike@redhat.com>
3570 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.
3572 * src/testpifbuf: Changed test program to display cdrom from rgb data
3573 if no filename given to test program.
3575 1999-10-07 Cody Russell <bratsche@dfw.net>
3576 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
3577 them, but I wrote them).
3579 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
3582 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
3583 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

3603 * src/io-tiff.c (image_load): ditto + fix leak
3605 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
3606 crashes this module ( add warning :-)
3608 * src/io-bmp.c (image_load): ditto.
3610 * src/io-gif.c (image_load): ditto.
3612 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
3614 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
3615 it doesn't crash scaling with alpha.
3617 1999-09-17 Federico Mena Quintero <federico@redhat.com>
3619 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
3621 * src/io-gif.c (image_load): Likewise.
3623 * src/io-jpeg.c (image_load): Likewise.
3625 * src/io-png.c (image_load): Likewise.

3640 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
3641 to unallocated memory (row_ptr), and fixed its type as well. Take
3642 into account the ArtPixbuf's rowstride when assigning the row
3645 * src/gdk-pixbuf.c: Fixup includes.
3647 * src/gdk-pixbuf-io.c: Likewise.
3649 Sat Jul 31 19:19:47 CEST 1999

3652 * src/io-png.c: Fixed two obvious C syntax bugs
3654 1999-07-29 Mark Crichton <crichton@gimp.org>
3656 * src/io-png.c (image_save): Added PNG saving function
3658 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
3659 image_save(GdkPixBuf *p, FILE *f, ...)
3662 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
3664 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3665 require extra libraries if we actually have those libraries.
3667 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3669 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
3670 * gdk_pixbufConf.sh.in: Added for gnome-config
3672 * configure.in: Modified to generate gdk_pixbufConf.sh
3674 1999-07-20 Mark Crichton <crichton@gimp.org>
3676 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3677 calculation needs to be done.
3679 1999-07-18 Larry Ewing <lewing@gimp.org>
3684 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3685 error cases but one or two in the common case. There are probably
3686 a few small ones left.
3688 1999-07-18 Mark Crichton <crichton@gimp.org>
3690 * configure.in: removed version.h.
3692 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3695 1999-07-17 Mark Crichton <crichton@gimp.org>
3697 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
3698 (gdk_pixbuf_rotate): Added pixbuf rotation code.

3701 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
3704 1999-07-16 Larry Ewing <lewing@gimp.org>
3706 * src/testpixbuf.c (expose_func): reverted the expose everything
3707 changes, I'm not sure why these went in.
3708 (config_func): bring this up to date with the new pixbuf_scale
3711 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3712 loading code so that poeple can diagnose problems better.
3714 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3715 no longer allocates a new pixbuf, which make things nicer for the
3716 rest of the code. Unfortunately there is still a problem with
3717 scaling rgba images.
3719 1999-07-16 Mark Crichton <crichton@gimp.org>
3721 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3722 calls gdk_pixbuf_scale. However, something is not working.
3723 N.B.: current pixmap is now stored in user_data with a key of
3726 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
3727 Something is still borked, however.
