216 * gdk-pixbuf-loader.c (struct GdkPixbufLoaderPrivate): Add
217 fields width, height, size_fixed, need_scale.
218 (gdk_pixbuf_loader_class_init): Add size_prepared signal.
219 (gdk_pixbuf_loader_set_size): New function.
220 (gdk_pixbuf_loader_size_func): ModuleSizeFunc which gets
221 passed to the module, emits size_prepared.
222 (gdk_pixbuf_loader_prepare): Call gdk_pixbuf_loader_size_func
223 if necessary, only emit area_prepared if no separate scaling
225 (gdk_pixbuf_loader_update): Only emit area_updated if no
226 separate scaling is required.
227 (gdk_pixbuf_loader_load_module): Add size_func as first argument.
228 (gdk_pixbuf_loader_close): If necessary scale the image

237 find the nearest possible output size which libjpeg can produce
238 that is still larger than the desired size.
240 2002-07-06 Matthias Clasen <maclas@gmx.de>
242 * io-tiff.c (tiff_set_error): Handle global_error == NULL
244 (tiff_image_parse): Don't trust TIFFRGBAImageBegin to set

254 on unchecked reallocs.
255 (DecodeHeader, DecodeColormap, decode_bitmasks,

257 throughout. Change signatures where necessary to pass the
259 (OneLine16): Fix loading of 16bpp BI_RGB bmps.
260 (DoCompressed): Rewritten to properly support BI_RLE4 and
263 Support for compressed ras images (#84994):
265 * io-ras.c (RAS2State): Error on unsupported ras variations.
266 (OneLine8): Fix colormap indexing.
267 (OneLine): Call updated_func with proper region.
268 (DoCompressed): New function, handles compressed ras data.
269 (gdk_pixbuf__ras_image_load_increment): Handle compressed ras
272 Better colorspace support for the jpeg loader (#61211):
274 * io-jpeg.c (convert_cmyk_to_rgb): New function.
275 (gdk_pixbuf__jpeg_image_load,
276 gdk_pixbuf__jpeg_image_load_increment): Allocate a pixbuf with
277 alpha for 4-channel jpegs and call convert_cmyk_to_rgb for these.
279 All of this needs to be merged to GNOME 1.4 gdk-pixbuf.
281 2002-06-28 Sven Neumann <sven@gimp.org>
283 * gdk-pixbuf-csource.c (print_blurb): converted a Tab to spaces.
285 Thu Jun 13 18:11:11 2002 Owen Taylor <otaylor@redhat.com>
287 * pixops/pixops.c: Fix problem where when no alpha was
288 involved, we scaled rather than composited, but then
289 went ahead and composited anyways. (#76958, Patch
290 from Matthias Clasen). Needs to be merged to GNOME
293 2002-06-13 Matthias Clasen <maclas@gmx.de>
295 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
296 incrementally display incrementally loaded progressive jpegs.
298 2002-06-07 Federico Mena Quintero <federico@ximian.com>
301 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
302 starting at a specific memory location. We do this instead of
303 GINT32_FROM_LE() as the latter is simply dereferences a cast,
304 which doesn't work on platforms with alignment requirements.
307 2002-06-01 Matthias Clasen <maclas@gmx.de>
309 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
310 with a C comment - those seem to be not uncommon, e.g. the Gimp
311 produces them. (#82706)
313 * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
315 (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.
317 2002-05-22 Tor Lillqvist <tml@iki.fi>
319 * gdk-pixbuf-io.c (get_libdir): Use GTK_BINARY_VERSION (and not
320 GTK_VERSION) in the path to the loaders on Win32, too.
322 * Makefile.am: Pass GTK_BINARY_VERSION.
324 2002-05-22 Federico Mena Quintero <federico@ximian.com>
326 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
327 account!!! Fixes #82515.
329 [This bug is not present in the GNOME 1.4 branch as its XPM loader
330 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
331 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
333 [IMPORTANT: The comment above is to make my life easier when
334 merging stuff across branches. If you make changes to gdk-pixbuf
335 in either branch, please include a comment in the ChangeLog that
336 indicates whether this should be merged into the other branch.
339 2002-05-18 Matthias Clasen <maclas@gmx.de>

354 2002-05-07 Michael Natterer <mitch@gimp.org>
356 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
357 conditionally like the dynamic ones so --without-lib<foo> is
358 honored when building with --disable-modules. (#66867)
360 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
362 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to
364 * test-loaders.c, test-images.h: remove
366 2002-04-24 Matthias Clasen <maclas@gmx.de>
368 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
369 restriction from the description of png tEXt parameters.
371 * io-png.c (png_text_to_pixbuf_option):
372 (gdk_pixbuf__png_image_save): If libpng supports it,
373 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
375 2002-04-11 Matthias Clasen <maclas@gmx.de>
377 More fixes for #77807:
379 * io-tga.c (get_contiguous_pixbuf): Helper function to create
380 a pixbuf with a contiguous pixel array while being careful about
383 * io-tga.c (fill_in_context, get_image_pseudocolor,
384 get_image_truecolor, get_image_grayscale): Use
385 get_contiguous_pixbuf instead of manually allocating image
388 * io-xpm.c (pixbuf_create_from_xpm):
389 * io-pnm.c (gdk_pixbuf__pnm_image_load):
390 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
391 instead of manually allocating image storage.
393 2002-04-09 Matthias Clasen <maclas@gmx.de>
395 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
396 priv->image_module->module_name instead of image_type which may
399 2002-04-06 Matthias Clasen <maclas@gmx.de>
401 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
402 gdk_pixbuf_new instead of manually allocating image storage. This
403 gives us a good rowstride and overflow checks. (#77807)
405 2002-04-05 Matthias Clasen <maclas@gmx.de>
407 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
408 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable

414 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_type): Fix a doc typo.
416 2002-03-29 Matthias Clasen <maclas@gmx.de>
418 * io-png.c (png_simple_error_callback): libpng error handlers must
419 not return to their callers, thus longjmp out. This prevents
420 annoying stderr output from the default error handler.
422 2002-03-27 Matthias Clasen <maclas@gmx.de>
424 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
426 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
427 end_info. Also call png_read_end to check proper ending of the png
428 file and catch text chunks after the image data.
430 2002-03-27 Matthias Clasen <maclas@gmx.de>
432 * io-png.c (gdk_pixbuf__png_image_load,
433 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
434 instead of system malloc.
436 2002-03-26 Matthias Clasen <maclas@gmx.de>
438 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
440 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
441 context->buf on error.
443 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
444 stop_load even for short images to prevent memleaks.
446 2002-03-25 Matthias Clasen <maclas@gmx.de>
448 * io-png.c (setup_png_transformations): Changed signature to
449 return success and set a GError parameter, adjusted all callers.
450 Also work around a possible FPE in libpng and always check that
451 the new info is sane.
453 2002-03-23 Matthias Clasen <maclas@gmx.de>
455 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
456 context->updated_func is NULL during a nonincremental load.
457 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
459 2002-03-18 Matthias Clasen <maclas@gmx.de>
461 * io-tga.c: Fix assumptions on rowstride by manually allocating a
462 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
463 Support grayscale + alpha (which can be written, but not read (!)
466 2002-03-15 Matthias Clasen <maclas@gmx.de>
468 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
470 2002-03-13 Matthias Clasen <maclas@gmx.de>
472 * test-images.h: Add valid_ras_test and invalid_bmp_1.
474 * test-loaders.c (main): Add random tests for ras and pnm and an
475 invalid bmp which was a crasher until my 2002-03-12 commit.
477 * io-pnm.c (gdk_pixbuf__pnm_image_load_increment): Don't unref the
480 * io-ras.c: Handle some errors.
482 2002-03-12 Sven Neumann <sven@gimp.org>
484 * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
485 calling memcpy(). Simpler and potentially faster. (#70332)
487 2002-03-12 Matthias Clasen <maclas@gmx.de>
489 * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
490 which could actually be reached by a proper error status return.
492 2002-03-05 Matthias Clasen <maclas@gmx.de>
494 * test-loaders.c, test-images.h: More random tests.
496 * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.
498 Tue Mar 5 10:39:03 2002 Owen Taylor <otaylor@redhat.com>
500 * Makefile.am (loaderdir): Put the modules into the
501 GTK_BINARY_VERSION directory for consistency with
502 immodules and theme engines.
504 Sat Mar 2 22:11:10 2002 Owen Taylor <otaylor@redhat.com>
506 * gdk-pixbuf-io.c (_gdk_pixbuf_load_module): If we
507 can't load the module using the g_module_build_path()
508 filename, try loading it as a .la file.
510 * test-loaders.c: Look for modules in current directory
511 rather than .libs, so we find the right .la files.
513 * test-loaders.c: Back out some accidental commits.
515 Sat Mar 2 21:28:03 2002 Owen Taylor <otaylor@redhat.com>
517 * gdk-pixbuf.c (gdk_pixbuf_new): Bullet-proof against integer
520 2002-03-03 Tor Lillqvist <tml@iki.fi>

533 * pixops/pixops.c (tile_make_weights): Move the call to
534 correct_total() to the right spot. (#72732)
536 Wed Feb 27 18:33:04 2002 Owen Taylor <otaylor@redhat.com>
538 * gdk-pixdata.c (gdk_pixdata_to_csource): Use {} not
539 () to group around string assigned to char[]. (#72767,
542 2002-02-21 Havoc Pennington <hp@pobox.com>

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

943 - four valid ppm's, eight invalid (matthiasc@poet.de)
944 - one invalid xpm (matthiasc@poet.de)
945 - one valid tga, one invalid (sandmann@daimi.au.dk)
946 - one invalid tiff (sandmann@daimi.au.dk
948 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
950 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
951 fail - detect it when it happens

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

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

1008 * pixops/pixops.c: applied some simple but effective optimizations

1011 2001-08-07 Sven Neumann <sven@gimp.org>
1013 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
1014 function, so that's what I did.

1081 on their own (gimp, BEAST).
1083 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
1084 program that can dump images in CSource format and Pixbuf
1085 stream format. supports RLE encoding, MACRO formatting etc...
1088 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
1090 * Makefile.am: Actually update timestamps, so rules don't
1093 2001-06-11 Havoc Pennington <hp@redhat.com>
1095 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
1096 already includes top_builddir
1098 2001-06-08 Havoc Pennington <hp@redhat.com>
1100 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
1101 bogus g_return_if_fail
1103 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
1104 likely timeout resolution, set it to an arbitrarily-chosen short
1106 Fixes bug #55953 from warmenhoven@yahoo.com
1108 2001-06-07 Havoc Pennington <hp@redhat.com>
1110 * Makefile.am: use Owen's new way of doing stampfiles/generated
1113 2001-06-07 Havoc Pennington <hp@redhat.com>
1115 * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path
1117 2001-06-05 Havoc Pennington <hp@redhat.com>
1119 * test-loaders.c (main): use putenv not setenv, reported by
1122 2001-05-08 Havoc Pennington <hp@redhat.com>
1124 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1125 and fix behavior to still subst color if the original image
1128 2001-06-04 Havoc Pennington <hp@redhat.com>
1130 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1133 2001-06-01 Havoc Pennington <hp@redhat.com>
1135 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1136 Makes things a bit more robust, and adds test-loaders.c
1137 which is good for finding further robustness bugs to fix.
1139 * io-tiff.c: Try to work around libtiff suckiness a bit;
1140 put a giant thread lock on the whole loader,
1141 paranoically check both whether error handlers were called and
1142 also whether functions return false. Handle case where width or
1143 height is 0. Various cleanups.
1145 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1147 (png_error_callback): apparently libpng expects you to longjmp out
1150 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1151 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1153 (gif_get_lzw): check for out-of-memory
1154 (gif_prepare_lzw): catch/report an error
1155 (new_context): use try_malloc, since GifContext is nearly 70K
1156 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1157 so we don't crash later.
1159 * Makefile.am: Add test-loaders
1161 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1164 2001-05-29 Darin Adler <darin@eazel.com>
1166 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1168 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1170 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1171 fix up bmp decoder to:
1172 - adds 16 bpp bmp support (bug #53884)
1173 - adds OS/2 1.x format bmp support (bug #54964)
1174 - adds 4 bpp RLE compressed bmp support
1175 - adds 1 bpp colormap support
1176 - fixes negative height (top down) bmp support
1178 2001-05-25 Hans Breuer <hans@breuer.org>
1180 * gdk_pixbuf.def : reflect Havoc's recent api change
1182 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1184 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1185 excess $(GLIB_LIBS).
1187 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1189 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1191 2001-05-04 Havoc Pennington <hp@redhat.com>
1193 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1194 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1197 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1198 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1199 confusion of using "src" instead of "p".
1200 (pixops_composite_color_nearest): Use a more accurate (and
1201 correct, to begin with) compositing method. This cures checks
1202 showing through on images with no alpha.
1204 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1207 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1209 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1210 area_updated signal to use signed ints. Removed animation-related
1213 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1216 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1217 all the pesky details. Remove old frame-based API. Make
1218 GdkPixbufAnimation an abstract base class, derived by the loaders.
1220 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1222 * Makefile.am (LDADDS): Add $(MATH_LIB).
1224 2001-04-18 Havoc Pennington <hp@redhat.com>
1226 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1229 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1231 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1232 so we don't try to get <gtk/gtkobject.h> from standard search
1235 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1236 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1237 take gdk-pixbuf-marshal.h out of _la sources.
1239 2001-03-19 Tor Lillqvist <tml@iki.fi>
1241 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1243 * gdk_pixbuf.def: Update.
1245 * pixbufloader_*.def: Just export the fill_vtable functions now.
1247 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1249 * make-inline-pixbuf.c (main): Added logic to remove output when
1252 2001-03-14 Havoc Pennington <hp@redhat.com>
1254 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1255 from gdk-pixbuf-marshal.h, fixes parallel makes.
1257 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1259 * test-gdk-pixbuf.c: fixed includes.
1261 2001-02-18 Havoc Pennington <hp@pobox.com>
1263 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1264 (gdk_pixbuf_get_named_module): prepend underscore
1265 (gdk_pixbuf_get_module): prepend underscore
1267 2001-02-19 Havoc Pennington <hp@redhat.com>
1269 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1271 2001-02-17 Havoc Pennington <hp@pobox.com>
1273 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1275 2001-02-07 Alexander Larsson <alexl@redhat.com>
1277 * io-xpm.c (free_buffer):
1278 Use g_free, since the buffer is allocated with g_try_alloc().
1280 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1282 * gdk-pixbuf-data.c: Fixes a minor typo.
1284 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1286 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1287 we finally need the gobject->gruntime rename.
1289 * *.c: scratched calls to g_type_init(), there's simply no point in
1290 doing that, use gtk_init().
1292 2001-02-01 Havoc Pennington <hp@pobox.com>
1294 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1295 in struct to "priv" for C++
1297 2001-01-31 Havoc Pennington <hp@pobox.com>
1299 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1301 2001-01-26 Havoc Pennington <hp@redhat.com>
1303 * gdk-pixbuf-io.c (mname): fix included modules case.
1305 2001-01-22 Havoc Pennington <hp@redhat.com>
1307 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1308 from gdk_pixbuf_load_module
1310 2001-01-22 Havoc Pennington <hp@redhat.com>
1312 * Makefile.am: Add built marshaller files to support
1313 GdkPixbufLoader signals
1315 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1316 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1317 module location, rather than acting as a fallback, because we are
1318 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1320 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1322 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1323 from gtk, and add error to close(), because stop_load may do
1324 parsing of the image.
1326 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1328 * io-*.c: make individual operations static, and add fill_vtable
1329 functions which are exported. Fix the collection of type warnings
1330 that surfaced, including a number of functions that didn't
1331 properly take a GError and some that weren't
1332 const-correct. Involved adding error handling for a few loaders.
1334 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1336 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1337 a function that fills in the GdkPixbufModule vtable, instead of
1338 looking up all the image functions individually; this means we
1339 can get type safety within modules for the loader functions.
1340 Also it means you don't have to keep the statically compiled and
1341 GModule versions in sync.
1343 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1345 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1347 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1349 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1352 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1354 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1357 2001-01-20 John Harper <jsh@eazel.com>
1359 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1360 collision between Xlib's RdBitF.c and io-tiff.c
1362 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1365 [ merged from stable gdk-pixbuf module. Untested, but it
1366 compiles, and works fine in the stable module ]
1368 2001-01-18 Tor Lillqvist <tml@iki.fi>
1370 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1371 g_win32_get_package_installation_subdirectory() function. No need
1372 to include windows.h.
1373 (gtk_win32_get_installation_directory): Remove this then.
1375 2001-01-01 Havoc Pennington <hp@redhat.com>
1377 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
1378 @LIBTOOL_EXPORT_OPTIONS@
1380 2000-12-30 Tor Lillqvist <tml@iki.fi>
1382 * gdk_pixbuf.def: Update.
1384 2000-12-16 Havoc Pennington <hp@pobox.com>
1386 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1387 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1388 (gdk_pixbuf_frame_copy): new function
1389 (gdk_pixbuf_frame_free): new function
1390 (gdk_pixbuf_frame_get_type): new function
1391 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
1393 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
1395 * Makefile.am: Add -avoid-version for all modules.
1397 2000-11-13 Havoc Pennington <hp@redhat.com>
1399 * io-png.c (png_simple_error_callback): fix error message to not
1400 say "save" since it's used for loading
1402 2000-11-11 Hans Breuer <Hans@Breuer.Org>
1404 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1405 contained image handlers (!USE_G_MODULE). Files to save should
1406 be opened in binary mode, fopen(s, "wb").
1408 * io-xpm.c : added HAVE_UNISTD_H condition
1410 2000-11-11 Tor Lillqvist <tml@iki.fi>
1412 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1414 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1415 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1416 mktemp() and open()).
1418 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1420 2000-11-01 Havoc Pennington <hp@pobox.com>
1422 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1423 a pixbuf pointing to a subregion of another pixbuf.
1425 2000-10-16 Tor Lillqvist <tml@iki.fi>
1427 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1429 2000-10-16 Havoc Pennington <hp@redhat.com>
1431 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1432 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1433 add error reporting here also

1448 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1451 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1452 a G_FILE_ERROR if we fail to write or close the file.
1454 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1455 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1456 the GError naming rules. Add GError** to load functions.
1458 2000-10-06 Havoc Pennington <hp@redhat.com>
1460 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1462 2000-10-06 Havoc Pennington <hp@redhat.com>

1627 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1629 * makefile.mingw.in: List loaders alphabetically. Add the wbmp

1648 * pixops/makefile.mingw.in
1649 * pixbuf_*.def: New files.
1652 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1654 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1655 New function, to get the GTK+ installation directory from
1656 the Windows Registry, where the installation program
1657 for whatever software includes GTK+ has stored it.
1659 Used to avoid having hardcoding the directory where to look for
1660 loaders. This function is needed by gtk, too, so it should
1661 really be just in one place. Maybe a small static library
1662 one level up from here?
1664 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1665 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1666 Open file in binary mode. This *is* standard C. (No-op on Unix,
1669 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1671 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1672 mktemp() and open().
1673 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1675 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1676 pseudo-op. Conditionalise on __MINGW32__, but probably
1677 should conditionalise on Gas version instead? Or could we
1678 do without .type on all systems?
1680 * pixops/timescale.c: Use g_get_current_time()
1681 instead of gettimeofday().
1683 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1685 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1687 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1689 * gdk-pixbuf.c: Add <string.h> include.
1691 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1693 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1694 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1695 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1696 use g_object_new() instead of g_type_create_instance() which
1697 is a private function for fundamental type implementations.
1699 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1701 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1702 soname scheme for gdk-pixbuf.
1704 2000-06-21 Havoc Pennington <hp@pobox.com>
1706 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1707 (i.e. derivation is not allowed, and there are no virtual methods
1709 (gdk_pixbuf_preinit): Call g_type_init() here.
1710 (gdk_pixbuf_init): Add a user-friendly init function, for users
1711 of standalone gdk-pixbuf
1713 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1714 way GdkPixbufAnimation was done.
1716 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1717 gdk_pixbuf_finalize() from API, since these are broken and don't
1718 make sense with new GObject stuff.
1720 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1722 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1723 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1726 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1728 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1729 so I needed something to warm my thighs. Running plain infinite
1730 loops on your laptop to make it hot is not very much fun. A demo
1731 of the gdk-pixbuf scaling functions is way better, and looks
1734 * configure.in (AC_OUTPUT): Added the demo Makefile.
1736 * Makefile.am (SUBDIRS): Added the demo directory.
1738 2000-06-09 Larry Ewing <lewing@helixcode.com>
1740 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1741 setjmp for the png error handler. It seems setting the error
1742 handling functions does not avoid the jump, and so not calling
1743 setjmp was causing the incremental loader to jump into lala land.
1744 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1745 not sure this one is actually required but the docs say it must be
1746 set for every call to a png_* function.
1747 Also changed the comment to reflect the fact that setting the
1748 error handlers does _not_ avoid the longjmp.
1750 2000-06-06 Larry Ewing <lewing@helixcode.com>
1752 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1753 take frame offest into account when trying to calculate the
1754 animation bbox. Also set the width to the width not the height.
1755 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1756 calculate bbox because now we finally have all the offset
1757 information for each frame.
1759 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1761 * configure.in: add some gtk parameters to the
1762 GDK_PIXBUF_LIBÃ�²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1763 fight in my crusade for strange prefix compile...
1765 2000-05-30 Not Zed <NotZed@HelixCode.com>
1767 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
1768 Initialise the error handler exit routine to our own. Note this
1769 means that every function that accesses the jpeg lib on this
1770 object MUST do a setjmp.
1771 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
1772 lib for handling fatal error.
1773 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
1774 your applications dont quit if there's a jpeg error!
1776 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
1778 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
1779 from Frank de Lange <frank@unternet.org>.
1781 2000-05-09 Darin Adler <darin@eazel.com>
1783 * gdk-pixbuf/test-gdk-pixbuf.c:
1784 Fixed includes to get rid of accidental GNOME dependency.
1786 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
1787 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
1789 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
1791 * configure.in: Bumped version number to 0.8.0.
1793 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
1794 file was not being distributed.
1796 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
1798 2000-05-09 Darin Adler <darin@eazel.com>
1800 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
1801 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
1802 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
1803 formats to 32-bit formats to re-use the high bits of the color values
1804 so that white maps to full white.
1806 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
1808 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
1809 detailed information about the structure and algorithms
1810 of pixops so people can fix it instead of breaking it.
1812 2000-05-04 Darin Adler <darin@eazel.com>
1814 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
1815 (composite_pixel), (composite_line):
1816 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
1817 Now that Owen explained the algorithm, I think I implemented it
1818 right for the cases where the destination pixbuf is not opaque.
1819 The test does seem to confirm it.
1821 2000-05-04 Darin Adler <darin@eazel.com>
1823 * gdk-pixbuf/.cvsignore:
1824 * gdk-pixbuf/Makefile.am:
1825 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
1826 (load_pixel), (simple_composite_test_one),
1827 (simple_composite_test_one_type), (simple_composite_test), (main):
1828 Added some tests of composite to highlight problems in the old
1829 implementation. These tests run without any user interaction.
1830 Just do "make check".
1832 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
1833 (composite_pixel), (composite_line): Fix composite to do a textbook
1834 "A over B" composite. This was clearly the intent, and it was easy
1835 to fix the code to do it. (Note to those that read my earlier tries
1836 at a patch; this version fixes typos that were present in all
1837 my patch attempts. I checked the final version by adding more tests.)
1839 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
1841 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
1842 offset y coordinate accordining to render_y0.
1844 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
1847 2000-04-22 James Henstridge <james@daa.com.au>
1849 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
1850 package to the devel package. The only file installed in bin is
1851 gdk-pixbuf-config, which belongs in -devel. This should allow having
1852 multiple versions of the main gdk-pixbuf package installed.
1854 2000-04-17 Karl Eichwalder <ke@suse.de>
1856 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
1857 Reported by Jens Finke.
1859 2000-04-14 Tomasz KÃ�³opczko <kloczek@pld.org.pl>
1861 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
1862 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
1864 2000-04-13 James Henstridge <james@daa.com.au>
1866 * configure.in: when performing the configure check to see if
1867 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
1868 rather than the other way round. Also, call AC_MSG_RESULT in the
1869 even that dynamic modules were not supported.
1871 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
1873 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
1874 hook to the last unref operation.
1876 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
1877 function to set the last unref handler for a pixbuf.
1878 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
1879 It calls the pixbuf's destroy notification function and frees the
1880 GdkPixbuf structure itself.
1881 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
1884 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
1885 for the last unref handler and its user data.
1887 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
1888 g_new0() to allocate the pixbuf.
1890 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
1891 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
1892 was not specifying the `frame' argument.
1894 * gdk-pixbuf/gdk-pixbuf-animation.c
1895 (gdk_pixbuf_animation_get_width): Fixed docstring.
1896 (gdk_pixbuf_animation_get_height): Likewise.
1897 (gdk_pixbuf_animation_get_num_frames): Likewise.
1898 (gdk_pixbuf_animation_get_frames): Likewise.
1900 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1903 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1905 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1907 * doc/tmpl/refcounting.sgml: Updated with the information about
1908 the last unref handler.
1910 * doc/tmpl/*.sgml: Markup tweaks.
1912 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1913 update the libtool version number for libgnomecanvaspixbuf as
1915 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
1916 as well, or the old ones won't work with the new stuff. Also,
1917 renamed the modules as follows.
1919 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
1920 modules are called "libpixbufloader-<format>.so" instead of
1921 "libpixbuf-<format>.so". They needed renaming so that the new
1922 loaders won't overwrite the old ones; even with the versioning
1923 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
1926 2000-04-12 Paolo Molaro <lupus@debian.org>
1928 * .cvsignore, src/.cvsignore: shut up cvs.
1930 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
1932 Most of this patch is based on a patch by Havoc Pennington
1933 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
1934 remove the libart dependency.
1936 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
1937 (GdkColorspace): New enum that for now only contains
1939 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
1940 notification function.
1941 (GdkInterpType): New num with interpolation types.
1943 * *.[ch]: Replace the libart stuff with our own stuff.
1945 * pixops/*.[ch]: Likewise.
1947 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
1948 declarations of the GdkPixbuf structures.
1950 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
1952 (gdk_pixbuf_get_format): Constify.
1953 (gdk_pixbuf_get_n_channels): Constify.
1954 (gdk_pixbuf_get_has_alpha): Constify.

1957 (gdk_pixbuf_get_width): Constify.
1958 (gdk_pixbuf_get_height): Constify.
1959 (gdk_pixbuf_get_rowstride): Constify.
1961 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
1964 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
1965 bits_per_sample argument; currently only 8 bits per sample are
1968 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
1970 (gdk_pixbuf_frame_get_x_offset): New accessor.
1971 (gdk_pixbuf_frame_get_y_offset): New accessor.
1972 (gdk_pixbuf_frame_get_delay_time): New accessor.
1973 (gdk_pixbuf_frame_get_action): New accessor.
1975 * gdk-pixbuf/gdk-pixbuf-render.c
1976 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
1977 mask rectangle for pixbufs without an alpha channel, set the
1978 *mask_return to NULL.
1980 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
1982 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
1984 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
1985 preconditions. Maybe we should also check for the colorspace,
1986 bits per pixel, and such.
1987 (gdk_pixbuf_composite): Likewise.
1988 (gdk_pixbuf_composite_color): Likewise.
1989 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
1990 cannot allocate the new pixbuf.
1991 (gdk_pixbuf_composite_color_simple): Likewise.
1993 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
1994 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
1997 * gdk-pixbuf/io-bmp.c: Fix includes.
1999 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
2004 * configure.in: Removed checks for libart.
2006 * gdk-pixbuf/Makefile.am: Removed references to libart.
2007 (noinst_HEADERS): Added gdk-pixbuf-private.h.
2009 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
2010 the version number of the libtool library to indicate that this
2011 definitely is not compatible with the old usage. I know you love
2014 * configure.in: Bumped version number to 0.7.0.
2018 * gdk-pixbuf-config.in (--libs): We no longer require libart.
2020 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
2022 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
2024 2000-04-06 Jonathan Blandford <jrb@redhat.com>
2026 * gdk-pixbuf/testanimation.c (main): add more info to the
2027 testanimation frames.
2029 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
2031 * gdk-pixbuf/gdk-pixbuf-animation.c
2032 (gdk_pixbuf_animation_get_width): New accessor function.
2033 (gdk_pixbuf_animation_get_height): New accessor function.
2034 (gdk_pixbuf_animation_get_num_frames): New accessor function.
2035 (gdk_pixbuf_animation_get_frames): New accessor function.
2037 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
2039 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
2040 is private information, and the art_pixbuf will go away soon.
2042 2000-03-31 Mark Crichton <crichton@gimp.org>
2044 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
2045 and gdk_pixbuf_get_artpixbuf accessor functions.
2047 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
2049 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
2050 gboolean instead of int.
2052 2000-03-29 Radek Doulik <rodo@helixcode.com>
2054 * gdk-pixbuf/gdk-pixbuf-animation.c
2055 (gdk_pixbuf_animation_new_from_file): same as below
2057 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
2058 height in GdkPixbufAnimation
2060 2000-03-28 Radek Doulik <rodo@helixcode.com>
2062 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
2063 context->frame_done_func and context->anim_done_func to make
2064 progressive animation loading work
2066 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
2067 added priv->pixbuf = NULL as pixbuf is now in frame (and to make
2068 gdk_pixbuf_loader_prepare happy)
2069 (gdk_pixbuf_loader_frame_done): update animation bbox
2071 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
2074 2000-03-27 Radek Doulik <rodo@helixcode.com>
2076 * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
2077 instead of width and height
2079 2000-03-27 Owen Taylor <otaylor@redhat.com>
2081 * gdk-pixbuf/pixops/pixops.c: Fix problem with
2082 precendence of >> and & which was keeping composite_color
2083 from working with non-gray images.
2085 2000-03-08 Jonathan Blandford <jrb@redhat.com>
2087 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.
2088 (gdk_pixbuf__gif_image_load_animation): free the context.
2090 2000-03-06 Arjan van de Ven <arjan@fenrus.demon.nl>
2092 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
2093 mis-interpretation of the Microsoft documentation. Now
2094 it can load .BMP files that are not generated by The Gimp
2097 2000-03-01 Mark Crichton <crichton@gimp.org>
2099 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
2100 fix the last auto* build bug (where we have libart, but no
2103 * gdk-pixbuf/Makefile.am: Same.
2105 2000-02-28 Matt Wilson <msw@redhat.com>
2107 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
2108 s/unsigned short/guint16/g, s/unsigned char/guint8/g
2110 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
2112 * README: We don't require libgif/ungif nor libXpm.
2114 * NEWS: This was outdated, so updated it.
2116 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
2118 * gdk-pixbuf.m4: Use the correct name for
2119 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing
2122 2000-02-21 Federico Mena Quintero <federico@helixcode.com>
2124 * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0.
2126 * doc/compiling.sgml: New appendix documenting the gdk-pixbuf
2127 library's particular options to configure.in.
2129 * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an
2132 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
2134 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
2135 Fixed typo in prototype name.
2137 * configure.in: Changed duplicated AC_MSG_CHECKING message to
2138 something more meaningful; now it is "checking whether dynamic
2141 * gdk-pixbuf/pixops/Makefile.am (noinst_PROGRAMS): Do not install
2142 the timescale program.
2144 Integrated Miguel de Icaza's <miguel@gnu.org> patch for optionally
2145 creating a single static library with all the image format modules
2148 2000-02-20 Miguel de Icaza <miguel@gnu.org>
2150 * gdk-pixbuf/io-xpm.c (gdk_pixbuf__xpm_image_load): Add prefix.
2151 (gdk_pixbuf__xpm_image_load_xpm_data): Add prefix.
2153 * gdk-pixbuf/io-tiff.c (gdk_pixbuf__tiff_image_load_real): Add prefix.
2154 (gdk_pixbuf__tiff_image_stop_load): Add prefix.
2155 (gdk_pixbuf__tiff_image_load_increment): Add prefix.

2514 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
2515 animation functions here.
2516 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
2517 animation if the loader does not support multiframe loading and
2518 the single-frame load returned NULL. Check that the filename is
2519 not NULL. Updated inline documentation.
2520 (gdk_pixbuf_animation_ref): New function.
2521 (gdk_pixbuf_animation_unref): New function.
2522 Removed gdk_pixbuf_animation_destroy() in favor of reference

2530 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
2533 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
2534 with a reference count of 1.
2536 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
2537 gdk-pixbuf-animation.c.
2539 * doc/tmpl/animation.sgml: Populated. It is still missing a
2540 description of the overlay modes.

2556 1999-12-23 Havoc Pennington <hp@pobox.com>
2558 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
2559 set to NULL here (specifically context->animation) was not being
2560 set to NULL. use g_new0() to alloc the struct.
2562 1999-12-20 Jonathan Blandford <jrb@redhat.com>
2564 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2565 correctly. Progressive loading needs some work, but that all
2566 needs doing from the gdk-pixbuf-loader end, not here.
2568 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2570 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2571 moved the file here. It seems natural to put this function here,
2572 as that's where the gdk_pixbuf_new_from_file function is, but it's
2573 still a little convoluted. The source files might be played with
2576 1999-12-14 Jonathan Blandford <jrb@redhat.com>

2590 * gdk-pixbuf/gnome-canvas-pixbuf.c
2591 (gnome_canvas_pixbuf_class_init): Renamed arguments to
2592 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for

2622 Filled in body of function.
2623 (rgbconvert): Added GdkColormap parameter, and to all conversion
2625 (convert_real_slow): New function - should convert ANY visual/data
2626 format properly, but it aint fast. Used as a fallback when an
2627 optimised routine wont match.
2628 (rgbconvert): Do very specific tests on the data format to verify
2629 properly if the optimised version will do, otherwise use the
2630 fallback function for all other data formats.
2632 * gdk-pixbuf/Makefile.am: Re-enabled building of
2633 textpixbuf-drawable.
2635 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
2636 gdk_pixbuf_get_from_drawable().
2638 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
2640 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red

2647 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2648 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2649 checks and API definition. The body needs filling in and it needs
2650 to do the Right Thing(tm) for pixmaps plus the given colormap and
2651 windows and their own colormaps.
2653 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2654 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
2656 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
2658 * doc/tmpl/from-drawables.sgml: Populated.

2691 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2692 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2693 want, send me a patch to do the conditional stuff properly.
2694 Otherwise, please read the GNOME Programming Guidelines,
2695 especially the "CVS policies" section.
2697 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>

2807 1999-11-29 Owen Taylor <otaylor@redhat.com>
2809 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
2810 Keep the mask around until after we draw ... since
2811 the GC changes aren't flushed to the X server until we
2812 draw, destroying it before that may result in BadPixmap
2815 1999-11-30 Havoc Pennington <hp@pobox.com>
2817 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
2819 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
2821 1999-11-29 Federico Mena Quintero <federico@redhat.com>
2823 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
2824 should be made conditional, not blindly commented out.
2826 1999-11-29 Jonathan Blandford <jrb@redhat.com>
2828 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
2829 handle .ico files. Cool.
2831 1999-11-24 Jonathan Blandford <jrb@redhat.com>
2833 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
2836 1999-11-24 James Henstridge <james@daa.com.au>
2838 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
2839 top builddir rather than src. This still builds fine, and does not
2840 get gtk-doc into an infinite loop when trying to find all the source
2843 1999-11-23 Jonathan Blandford <jrb@redhat.com>
2845 * Removed #PRAGMA } from headers. Also, make compile if you don't
2846 have it installed, already.
2848 1999-11-22 Federico Mena Quintero <federico@redhat.com>
2850 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
2851 temporary buffer to the size of the interesction of the bounding
2852 box and the expose area, not the whole expose area. This speeds
2855 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
2856 not paint black on the mask, since we already cleared it in a
2857 single gdk_draw_rectangle() operation.
2859 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
2861 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
2863 1999-11-22 Havoc Pennington <hp@pobox.com>
2865 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
2866 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
2867 dependencies to LIBADD variables for loadable modules. Necessary
2868 for a Java dynamic loading thing to be able to figure it out.
2870 1999-11-22 Havoc Pennington <hp@pobox.com>
2872 * src/io-png.c (image_load_increment): Call the update_area
2873 callback depending on the number of rows loaded in this increment.
2875 * src/testpixbuf.c (main): slow down the progressive load demo
2877 1999-11-16 Havoc Pennington <hp@pobox.com>
2879 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
2881 1999-11-22 Jonathan Blandford <jrb@redhat.com>
2883 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
2884 for srcdir != buildir != . Beats me why; I can't figure it out.
2885 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
2887 1999-11-21 Jonathan Blandford <jrb@redhat.com>
2889 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
2890 <arjan@fenrus.demon.nl>
2892 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2894 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
2895 Rework/reorder of the code. Each case has been separated into
2896 another function; its big but it should be quick.
2897 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
2898 opaque alpha information. Not all depths/formats have been
2899 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
2901 1999-11-17 Larry Ewing <lewing@gimp.org>
2903 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2904 implement the bounds method correctly.
2905 (compute_viewport_affine): compute the affine need to fit the
2906 image within the viewport given by the args.
2907 (compute_render_affine): call compute_viewport_affine.
2909 1999-11-16 Havoc Pennington <hp@pobox.com>
2911 * src/gdk-pixbuf-drawable.h: Use includes from the current
2912 directory, not the system directory.
2914 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
2916 * src/testpixbuf-drawable.c: use includes from the current directory
2917 rather then from the system include directory as gdk-pixbuf
2918 includes are not yet installed when this is compiled.
2920 1999-11-13 Cody Russell <bratsche@dfw.net>
2921 * src/testpixbuf-drawable.c: Added a test program for drawable
2924 * src/Makefile.am: Build testpixbuf-drawable.

2944 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
2945 correctly. Patch from Arjan to do so.
2947 1999-11-10 Michael Fulbright <drmike@redhat.com>
2949 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM

2970 1999-11-09 Michael Fulbright <drmike@redhat.com>
2972 * src/testpixbuf.c: Fixed it to use timeout to read from file
2973 for progressive loading. Set TBF_KBPS=n, where n is the number of
2974 kilobytes/second to simulate in downloading. n has to be an integer.
2976 * src/io-jpeg.c: Slight cosmetic cleanup.
2978 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
2979 PBM loading has a similar problem and will address tomorrow.
2981 1999-11-09 Havoc Pennington <hp@pobox.com>
2983 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
2984 gdk-pixbuf-drawable stuff.
2986 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2988 * configure.in: Bumped version number to 0.4.
2990 1999-11-09 Michael Fulbright <drmike@redhat.com>
2992 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
2993 all types of PNM files now.
2995 * src/io-jpeg.c (image_load_increment): Figured out problem with
2996 loading Progressive JPEG's progressively (say that 10 times fast).
2997 Currently for Progressive JPEG's the entire image is loaded before
2998 it is displayed. libjpeg supports a fancier mechanism which I may
3001 With these changes all JPEG formats appear to load properly for me.
3003 1999-11-08 Jonathan Blandford <jrb@redhat.com>
3005 * src/io-ras.c (image_load_increment): Final patch from Arjan.
3006 Seems to do progressive loading.
3008 1999-11-08 Michael Fulbright <drmike@redhat.com>
3010 * src/io-pnm.c image_load (): Fixed so we do not create a separate
3011 pixel buffer when reading in image - we reuse the pixel data in
3012 the GdkPixbuf structure instead.
3014 1999-11-08 Michael Fulbright <drmike@redhat.com>
3016 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
3017 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
3018 I can't seem to find a utility to convert into this format.
3019 Next is to add progressive loading support for the PNM format.
3021 1999-11-07 Federico Mena Quintero <federico@redhat.com>
3023 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation

3033 * src/io-ras.c (image_load): new file from Arjan van de Ven
3034 <arjan@fenrus.demon.nl> to begin the ras loader.
3036 1999-11-05 Federico Mena Quintero <federico@redhat.com>

3072 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3073 this function vs. gdk_pixbuf_render_to_drawable().
3075 1999-11-04 Havoc Pennington <hp@pobox.com>
3077 * configure.in: Use libart-config correctly; find gnome-config
3078 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3081 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3084 Patch untested in the inside-gnome-libs case, I need to commit
3085 then check out to the gnome-libs I'm using.

3188 1999-11-03 Michael Fulbright <drmike@redhat.com>
3190 * src/io-jpg.c (image_load_increment): Fixed code which moved
3191 buffer around as new data comes in to work properly. JPEG progressive
3192 loading should be working now except for grayscale JPEG's, which I
3193 will look into next.
3195 1999-11-03 <sopwith@redhat.com>
3196 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
3197 Also put dot printing back in.
3199 1999-11-03 <jrb@redhat.com>
3201 * src/io-gif.c (gif_get_extension): Read 'til the next empty block

3231 instead of a full distance calculation since the canvas is going
3232 to change to that scheme, anyways.
3234 1999-11-02 Elliot Lee <sopwith@redhat.com>
3236 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
3237 that are read from the input file.
3239 1999-11-02 Larry Ewing <lewing@gimp.org>
3241 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
3243 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
3246 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3248 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3249 affine computation code from ::draw() to here, since it is needed
3250 by ::point() as well.
3252 1999-11-02 Elliot Lee <sopwith@redhat.com>
3254 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3255 three functions, and eliminate duplication of code from write()
3256 and close(). Also fix bug where the 128-byte header was being
3259 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3260 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3261 bounding box computation.
3263 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3265 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3266 Drawing affines seem to work. Bounding box is fubared. ::point()
3267 is not implemented. This is a work in progress.
3269 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3272 * configure.in: Sigh. We need to link in libgnomeui for the
3273 canvas stuff. This mess will disappear when gdk-pixbuf gets
3274 folded into gnome-libs.
3276 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3278 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3279 the right size, at a minimum, even if the image is squished and
3281 (ReadImage): lets get the offset right. This will let transparent
3284 1999-10-29 Michael Fulbright <drmike@redhat.com>
3286 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3287 image width was not a multiple of 4 - always use the
3288 gdk_pixbuf rowstride to increment pointers!
3290 1999-10-29 Michael Fulbright <drmike@redhat.com>
3292 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3293 Currently does not handle either progressive jpeg files (jpeg
3294 files with multiple scans at different quality settings), but
3295 I plan on adding this support soon. These are fairly rare in
3296 my experience, so it shouldn't slow people down too much.
3297 Grayscale jpegs also don't work but that should be easy to fix.
3299 1999-10-29 Michael Fulbright <drmike@redhat.com>
3301 * src/testpixbuf.c: Added title to windows so you can identify
3302 progressive and file windows.
3304 1999-10-29 Michael Fulbright <drmike@redhat.com>
3306 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3307 load the image handler when we determine the image type.
3309 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3310 previously static function load_image_handler () to
3311 a public function gdk_pixbuf_load_module (). It is needed in
3312 gdk-pixbuf-loader.c to load image handler modules. This function
3313 is different from gdk_pixbuf_get_module (), which only returns
3314 a reference to the required handler, because it actually loads
3315 the handler into memory. Both actions should possibly be combined
3316 in a convenience function since one w/o the other doesn't seem to
3319 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3321 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
3324 1999-10-28 Federico Mena Quintero <federico@redhat.com>
3326 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3327 function to render a portion of a pixbuf to a drawable. Ignores
3328 alpha information and takes in a GC.
3329 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3330 portion of a pixbuf to a drawable. It automatically creates a GC
3331 and a clipping mask for alpha pixbufs.
3333 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3335 * src/gdk-pixbuf.h: turned convenience macros into convenience
3336 functions so some error checking could be added.
3338 * src/io-tiff.c (image_load_increment): started work on the tiff
3339 non-incremental loader.
3340 (image_begin_load): Finished the incremental loader.
3342 * src/io-gif.c (image_load_increment): started work on the gif
3345 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
3347 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3349 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3350 function to threshold a pixbuf's alpha channel into a bitmap.
3352 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3353 contemplate future extensions to ArtPixBuf's formats.
3355 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3357 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3358 macros to fetch the ArtPixBuf's fields.
3360 1999-10-27 Havoc Pennington <hp@pobox.com>
3362 * src/testpixbuf.c (main): Display the progressive load
3364 * src/io-png.c (setup_png_transformations): Break transformation
3365 code into separate function
3366 (png_info_callback): Use setup_png_transformations
3368 1999-10-27 Havoc Pennington <hp@pobox.com>
3370 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3371 properly whether the XPM module has already been loaded
3372 (gdk_pixbuf_new_from_file): Check properly if loader module
3373 was already loaded (was checking if load symbol was present
3374 in order to decide whether to re-load; should check module !=
3375 NULL, then load != NULL)
3376 (image_handler_load): Check in present working directory,
3377 makes it easier to debug for now
3378 (file_formats): This array initializer was seriously on crack,
3379 was assigning a function pointer to a GModule*
3381 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
3383 1999-10-27 Havoc Pennington <hp@pobox.com>
3385 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_finalize):
3386 Fix typo that prevented compilation
3387 (gdk_pixbuf_loader_destroy): ditto
3389 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3391 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
3392 GdkPixbufLoader, not a GtkObject.
3393 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
3394 (gdk_pixbuf_loader_get_type): Documented.
3395 (gdk_pixbuf_loader_class_init): Initialize the parent class
3397 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
3398 class destroy function.
3399 (gdk_pixbuf_loader_new): Documented.
3400 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3402 (gdk_pixbuf_loader_write): Use size_t for count.
3404 1999-10-27 Michael Fulbright <drmike@redhat.com>
3406 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3407 logic so we only try to close loader if it wasn't previously closed.
3409 1999-10-27 Michael Fulbright <drmike@redhat.com>
3411 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of
3412 pixbuf_loader properly initialized.
3414 * src/testpixbuf.c: Made sure we cleanup pixbuf_loader properly
3417 1999-10-26 Jonathan Blandford <jrb@redhat.com>

3437 * configure.in (CFLAGS): Patch from Uwe Koloska
3438 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3440 1999-10-22 Havoc Pennington <hp@pobox.com>
3442 * src/io-xpm.c (mem_buffer): Clean up stupid
3443 increment-inside-array-dereference thing
3445 * src/testpixbuf.c: Add XPM data tests.
3447 * src/io-xpm.c: Make the XPM data buffer const, fix const
3448 correctness throughout the code.
3450 1999-10-22 Havoc Pennington <hp@pobox.com>
3452 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()
3454 1999-10-22 Havoc Pennington <hp@pobox.com>
3456 * src/io-xpm.c (image_load_xpm_data): Export this symbol for
3457 loading an XPM from memory.

3460 function, loads pixbuf from xpm data
3461 (image_handler_load): Add g_return_if_fail() to ensure the same
3462 module isn't loaded twice. Add g_module_symbol() to scan for XPM
3465 1999-10-22 Federico Mena Quintero <federico@redhat.com>
3467 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3468 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
3469 buffers; the rows can be read in directly into the main pixel
3472 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3474 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
3476 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3478 * configure.in: Bumped version number to 0.3.
3480 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
3481 version number for the library.
3483 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3485 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
3486 all memory management of the buffer is done by libart.
3488 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
3489 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
3491 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
3492 terms of the libart functions. Removed the old code.
3494 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
3495 symbols. Saving will not be implemented in GdkPixbuf.
3497 * src/io-gif.c: Removed the saving stub.
3498 (image_load): Fixed memory management to fail gracefully if we run
3499 out of memory while loading the image. Close the gif file when we
3500 are done. This still needs more error handling for the DGif
3503 * src/io-jpeg.c (image_load): Some robustness fixes.
3505 * src/io-png.c: Removed the saving stuff.
3506 (image_load): Some memory management fixes.
3508 * src/io-tiff.c (image_load): Ditto.

3516 * autogen.sh: use subautogen.sh
3518 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3520 * src/*: Reindented to use the GNOME Indentation. Renamed
3521 GdkPixBuf to GdkPixbuf, for consistency with the function names
3522 (and it is also easier to type) :-)
3524 1999-10-18 Havoc Pennington <hp@pobox.com>
3526 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
3528 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
3530 1999-10-18 Havoc Pennington <hp@pobox.com>
3532 * Makefile.am (SUBDIRS): Remove "macros"
3534 * configure.in: Don't use GNOME_INIT, handle case where we are
3535 inside gnome-libs. AM_PATH_GTK for the GIF test
3537 * src/Makefile.am: Change flags to work without libgnomeui,
3538 comment out testpixbuf for now
3540 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3542 * configure.in: Use $GTK_LIBS as the extra libs when checking for
3543 libgif/libungif, as they need the X libraries. Fixes bug #2472.
3545 1999-10-10 Cody Russell <bratsche@dfw.net>
3546 * src/gdk-pixbuf-drawable.c: core function now determines whether
3547 the requested geometry is on screen or not, and if some is not
3548 then the request is clamped to geometry that is on the screen.
3550 Changed 'pixbuf' to 'art_pixbuf' in core function.
3552 1999-10-08 Michael Fulbright <drmike@redhat.com>
3554 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.
3556 * src/testpifbuf: Changed test program to display cdrom from rgb data
3557 if no filename given to test program.
3559 1999-10-07 Cody Russell <bratsche@dfw.net>
3560 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
3561 them, but I wrote them).
3563 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
3566 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
3567 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.
3569 * src/gdk-pixbuf-drawable.c: Added #include "gdk-pixbuf-drawable.h"
3572 * src/gdk-pixbuf-drawable.[ch]: Changed functions to return
3573 GdkPixBuf* instead of ArtPixBuf*.

3585 * src/io-xpm.c (_pixbuf_create_from_xpm): ditto.
3587 * src/io-tiff.c (image_load): ditto + fix leak
3589 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
3590 crashes this module ( add warning :-)
3592 * src/io-bmp.c (image_load): ditto.
3594 * src/io-gif.c (image_load): ditto.
3596 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
3598 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
3599 it doesn't crash scaling with alpha.
3601 1999-09-17 Federico Mena Quintero <federico@redhat.com>
3603 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
3605 * src/io-gif.c (image_load): Likewise.
3607 * src/io-jpeg.c (image_load): Likewise.
3609 * src/io-png.c (image_load): Likewise.
3611 * src/io-tiff.c (image_load): Likewise.

3622 1999-08-09 Federico Mena Quintero <federico@nuclecu.unam.mx>
3624 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
3625 to unallocated memory (row_ptr), and fixed its type as well. Take
3626 into account the ArtPixbuf's rowstride when assigning the row
3629 * src/gdk-pixbuf.c: Fixup includes.
3631 * src/gdk-pixbuf-io.c: Likewise.
3633 Sat Jul 31 19:19:47 CEST 1999

3636 * src/io-png.c: Fixed two obvious C syntax bugs
3638 1999-07-29 Mark Crichton <crichton@gimp.org>
3640 * src/io-png.c (image_save): Added PNG saving function
3642 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
3643 image_save(GdkPixBuf *p, FILE *f, ...)
3646 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
3648 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3649 require extra libraries if we actually have those libraries.
3651 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3653 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
3654 * gdk_pixbufConf.sh.in: Added for gnome-config
3656 * configure.in: Modified to generate gdk_pixbufConf.sh
3658 1999-07-20 Mark Crichton <crichton@gimp.org>
3660 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3661 calculation needs to be done.
3663 1999-07-18 Larry Ewing <lewing@gimp.org>
3668 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3669 error cases but one or two in the common case. There are probably
3670 a few small ones left.
3672 1999-07-18 Mark Crichton <crichton@gimp.org>
3674 * configure.in: removed version.h.
3676 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3679 1999-07-17 Mark Crichton <crichton@gimp.org>
3681 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
3682 (gdk_pixbuf_rotate): Added pixbuf rotation code.
3683 (gdk_pixbuf_scale): Changed // comments to /* */
3685 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
3688 1999-07-16 Larry Ewing <lewing@gimp.org>
3690 * src/testpixbuf.c (expose_func): reverted the expose everything
3691 changes, I'm not sure why these went in.
3692 (config_func): bring this up to date with the new pixbuf_scale
3695 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3696 loading code so that poeple can diagnose problems better.
3698 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3699 no longer allocates a new pixbuf, which make things nicer for the
3700 rest of the code. Unfortunately there is still a problem with
3701 scaling rgba images.
3703 1999-07-16 Mark Crichton <crichton@gimp.org>
3705 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3706 calls gdk_pixbuf_scale. However, something is not working.
3707 N.B.: current pixmap is now stored in user_data with a key of
3710 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
3711 Something is still borked, however.

3724 handler for testpixbuf
3726 1999-07-13 Mark Crichton <crichton@gimp.org>
3728 * configure.in: Fixed GIF check. Replaced " with '
3729 * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale
3731 1999-07-13 Mark Crichton <crichton@gimp.org>
3733 * configure.in: I am a bonehead. Added gif-lib check.
