190 fields width, height, size_fixed, need_scale.
191 (gdk_pixbuf_loader_class_init): Add size_prepared signal.
192 (gdk_pixbuf_loader_set_size): New function.
193 (gdk_pixbuf_loader_size_func): ModuleSizeFunc which gets
194 passed to the module, emits size_prepared.

196 if necessary, only emit area_prepared if no separate scaling
198 (gdk_pixbuf_loader_update): Only emit area_updated if no
199 separate scaling is required.
200 (gdk_pixbuf_loader_load_module): Add size_func as first argument.
201 (gdk_pixbuf_loader_close): If necessary scale the image

204 size_prepared signal.
205 (gdk_pixbuf_loader_set_size) New API.

210 find the nearest possible output size which libjpeg can produce
211 that is still larger than the desired size.
213 2002-07-06 Matthias Clasen <maclas@gmx.de>
215 * io-tiff.c (tiff_set_error): Handle global_error == NULL
217 (tiff_image_parse): Don't trust TIFFRGBAImageBegin to set

230 throughout. Change signatures where necessary to pass the
232 (OneLine16): Fix loading of 16bpp BI_RGB bmps.
233 (DoCompressed): Rewritten to properly support BI_RLE4 and
236 Support for compressed ras images (#84994):
238 * io-ras.c (RAS2State): Error on unsupported ras variations.
239 (OneLine8): Fix colormap indexing.

241 (DoCompressed): New function, handles compressed ras data.
242 (gdk_pixbuf__ras_image_load_increment): Handle compressed ras
245 Better colorspace support for the jpeg loader (#61211):
247 * io-jpeg.c (convert_cmyk_to_rgb): New function.
248 (gdk_pixbuf__jpeg_image_load,
249 gdk_pixbuf__jpeg_image_load_increment): Allocate a pixbuf with
250 alpha for 4-channel jpegs and call convert_cmyk_to_rgb for these.
252 All of this needs to be merged to GNOME 1.4 gdk-pixbuf.
254 2002-06-28 Sven Neumann <sven@gimp.org>
256 * gdk-pixbuf-csource.c (print_blurb): converted a Tab to spaces.
258 Thu Jun 13 18:11:11 2002 Owen Taylor <otaylor@redhat.com>
260 * pixops/pixops.c: Fix problem where when no alpha was
261 involved, we scaled rather than composited, but then
262 went ahead and composited anyways. (#76958, Patch
263 from Matthias Clasen). Needs to be merged to GNOME
266 2002-06-13 Matthias Clasen <maclas@gmx.de>
268 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
269 incrementally display incrementally loaded progressive jpegs.
271 2002-06-07 Federico Mena Quintero <federico@ximian.com>
274 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
275 starting at a specific memory location. We do this instead of
276 GINT32_FROM_LE() as the latter is simply dereferences a cast,
277 which doesn't work on platforms with alignment requirements.
280 2002-06-01 Matthias Clasen <maclas@gmx.de>
282 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
283 with a C comment - those seem to be not uncommon, e.g. the Gimp
284 produces them. (#82706)
286 * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
288 (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.
290 2002-05-22 Tor Lillqvist <tml@iki.fi>
292 * gdk-pixbuf-io.c (get_libdir): Use GTK_BINARY_VERSION (and not
293 GTK_VERSION) in the path to the loaders on Win32, too.
295 * Makefile.am: Pass GTK_BINARY_VERSION.
297 2002-05-22 Federico Mena Quintero <federico@ximian.com>
299 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
300 account!!! Fixes #82515.
302 [This bug is not present in the GNOME 1.4 branch as its XPM loader
303 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
304 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
306 [IMPORTANT: The comment above is to make my life easier when
307 merging stuff across branches. If you make changes to gdk-pixbuf
308 in either branch, please include a comment in the ChangeLog that
309 indicates whether this should be merged into the other branch.
312 2002-05-18 Matthias Clasen <maclas@gmx.de>

327 2002-05-07 Michael Natterer <mitch@gimp.org>
329 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
330 conditionally like the dynamic ones so --without-lib<foo> is
331 honored when building with --disable-modules. (#66867)
333 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
335 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to
337 * test-loaders.c, test-images.h: remove
339 2002-04-24 Matthias Clasen <maclas@gmx.de>
341 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
342 restriction from the description of png tEXt parameters.
344 * io-png.c (png_text_to_pixbuf_option):
345 (gdk_pixbuf__png_image_save): If libpng supports it,
346 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
348 2002-04-11 Matthias Clasen <maclas@gmx.de>
350 More fixes for #77807:
352 * io-tga.c (get_contiguous_pixbuf): Helper function to create
353 a pixbuf with a contiguous pixel array while being careful about
356 * io-tga.c (fill_in_context, get_image_pseudocolor,
357 get_image_truecolor, get_image_grayscale): Use
358 get_contiguous_pixbuf instead of manually allocating image
361 * io-xpm.c (pixbuf_create_from_xpm):
362 * io-pnm.c (gdk_pixbuf__pnm_image_load):
363 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
364 instead of manually allocating image storage.
366 2002-04-09 Matthias Clasen <maclas@gmx.de>
368 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
369 priv->image_module->module_name instead of image_type which may
372 2002-04-06 Matthias Clasen <maclas@gmx.de>
374 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
375 gdk_pixbuf_new instead of manually allocating image storage. This
376 gives us a good rowstride and overflow checks. (#77807)
378 2002-04-05 Matthias Clasen <maclas@gmx.de>
380 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
381 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable

389 2002-03-29 Matthias Clasen <maclas@gmx.de>
391 * io-png.c (png_simple_error_callback): libpng error handlers must
392 not return to their callers, thus longjmp out. This prevents
393 annoying stderr output from the default error handler.
395 2002-03-27 Matthias Clasen <maclas@gmx.de>
397 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
399 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
400 end_info. Also call png_read_end to check proper ending of the png
401 file and catch text chunks after the image data.
403 2002-03-27 Matthias Clasen <maclas@gmx.de>
405 * io-png.c (gdk_pixbuf__png_image_load,
406 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
407 instead of system malloc.
409 2002-03-26 Matthias Clasen <maclas@gmx.de>
411 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
413 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
414 context->buf on error.
416 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
417 stop_load even for short images to prevent memleaks.
419 2002-03-25 Matthias Clasen <maclas@gmx.de>
421 * io-png.c (setup_png_transformations): Changed signature to
422 return success and set a GError parameter, adjusted all callers.
423 Also work around a possible FPE in libpng and always check that
424 the new info is sane.
426 2002-03-23 Matthias Clasen <maclas@gmx.de>
428 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
429 context->updated_func is NULL during a nonincremental load.
430 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
432 2002-03-18 Matthias Clasen <maclas@gmx.de>
434 * io-tga.c: Fix assumptions on rowstride by manually allocating a
435 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
436 Support grayscale + alpha (which can be written, but not read (!)
439 2002-03-15 Matthias Clasen <maclas@gmx.de>
441 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
443 2002-03-13 Matthias Clasen <maclas@gmx.de>
445 * test-images.h: Add valid_ras_test and invalid_bmp_1.
447 * test-loaders.c (main): Add random tests for ras and pnm and an
448 invalid bmp which was a crasher until my 2002-03-12 commit.
450 * io-pnm.c (gdk_pixbuf__pnm_image_load_increment): Don't unref the
453 * io-ras.c: Handle some errors.
455 2002-03-12 Sven Neumann <sven@gimp.org>
457 * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
458 calling memcpy(). Simpler and potentially faster. (#70332)
460 2002-03-12 Matthias Clasen <maclas@gmx.de>
462 * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
463 which could actually be reached by a proper error status return.
465 2002-03-05 Matthias Clasen <maclas@gmx.de>
467 * test-loaders.c, test-images.h: More random tests.
469 * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.
471 Tue Mar 5 10:39:03 2002 Owen Taylor <otaylor@redhat.com>
473 * Makefile.am (loaderdir): Put the modules into the
474 GTK_BINARY_VERSION directory for consistency with
475 immodules and theme engines.
477 Sat Mar 2 22:11:10 2002 Owen Taylor <otaylor@redhat.com>
479 * gdk-pixbuf-io.c (_gdk_pixbuf_load_module): If we
480 can't load the module using the g_module_build_path()
481 filename, try loading it as a .la file.
483 * test-loaders.c: Look for modules in current directory
484 rather than .libs, so we find the right .la files.
486 * test-loaders.c: Back out some accidental commits.
488 Sat Mar 2 21:28:03 2002 Owen Taylor <otaylor@redhat.com>
490 * gdk-pixbuf.c (gdk_pixbuf_new): Bullet-proof against integer

506 * pixops/pixops.c (tile_make_weights): Move the call to
507 correct_total() to the right spot. (#72732)
509 Wed Feb 27 18:33:04 2002 Owen Taylor <otaylor@redhat.com>
511 * gdk-pixdata.c (gdk_pixdata_to_csource): Use {} not
512 () to group around string assigned to char[]. (#72767,
515 2002-02-21 Havoc Pennington <hp@pobox.com>
517 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove

526 bilinear_make_weights): Use correct_total.
528 2002-02-10 Matthias Clasen <maclas@gmx.de>
530 * test-images.h (tiff1_test_3), test-loaders.c (main): Add a
531 (#ifdef 0'ed) test provoking a segfault in TIFFReadDirectory().
533 * io-ico.c (DecodeHeader): Check that pixbuf could be allocated.
535 * test-images.h (ico_test_2), test-loaders.c (main): Test the
538 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment): Don't write
539 beyond the end of buffer if width % 8 != 0.
541 * io-tga.c (try_preload): Enforce that ctx->hdr->type is one of
542 the supported types, otherwise parse_data_for_row () will not make
543 any progress, leading to an infinite loop.

851 Thu Sep 20 17:22:48 2001 Owen Taylor <otaylor@redhat.com>
853 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
854 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't
855 work here since we are using the raw file descriptor. So, we call lseek()
856 on the fileno(f) before using it. (#60840).

860 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,

916 - four valid ppm's, eight invalid (matthiasc@poet.de)
917 - one invalid xpm (matthiasc@poet.de)
918 - one valid tga, one invalid (sandmann@daimi.au.dk)
919 - one invalid tiff (sandmann@daimi.au.dk
921 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
923 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
924 fail - detect it when it happens
926 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
929 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
932 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
934 * Makefile.am: don't used BUILT_SOURCES to build marshal
935 files, as in conjunction with stamp files, this can
936 lead to endless rebuilding loops.

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

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

984 2001-08-07 Sven Neumann <sven@gimp.org>
986 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
987 function, so that's what I did.

1090 2001-06-05 Havoc Pennington <hp@redhat.com>
1092 * test-loaders.c (main): use putenv not setenv, reported by
1095 2001-05-08 Havoc Pennington <hp@redhat.com>
1097 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1098 and fix behavior to still subst color if the original image
1101 2001-06-04 Havoc Pennington <hp@redhat.com>
1103 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1106 2001-06-01 Havoc Pennington <hp@redhat.com>
1108 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1109 Makes things a bit more robust, and adds test-loaders.c
1110 which is good for finding further robustness bugs to fix.
1112 * io-tiff.c: Try to work around libtiff suckiness a bit;
1113 put a giant thread lock on the whole loader,
1114 paranoically check both whether error handlers were called and
1115 also whether functions return false. Handle case where width or
1116 height is 0. Various cleanups.
1118 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1120 (png_error_callback): apparently libpng expects you to longjmp out
1123 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1124 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1126 (gif_get_lzw): check for out-of-memory
1127 (gif_prepare_lzw): catch/report an error
1128 (new_context): use try_malloc, since GifContext is nearly 70K
1129 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1130 so we don't crash later.
1132 * Makefile.am: Add test-loaders
1134 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1137 2001-05-29 Darin Adler <darin@eazel.com>
1139 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1141 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1143 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1144 fix up bmp decoder to:
1145 - adds 16 bpp bmp support (bug #53884)
1146 - adds OS/2 1.x format bmp support (bug #54964)
1147 - adds 4 bpp RLE compressed bmp support
1148 - adds 1 bpp colormap support
1149 - fixes negative height (top down) bmp support
1151 2001-05-25 Hans Breuer <hans@breuer.org>
1153 * gdk_pixbuf.def : reflect Havoc's recent api change
1155 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1157 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1158 excess $(GLIB_LIBS).
1160 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1162 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1164 2001-05-04 Havoc Pennington <hp@redhat.com>
1166 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1167 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1170 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1171 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1172 confusion of using "src" instead of "p".
1173 (pixops_composite_color_nearest): Use a more accurate (and
1174 correct, to begin with) compositing method. This cures checks
1175 showing through on images with no alpha.
1177 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1180 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1182 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1183 area_updated signal to use signed ints. Removed animation-related
1186 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1189 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1190 all the pesky details. Remove old frame-based API. Make
1191 GdkPixbufAnimation an abstract base class, derived by the loaders.
1193 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1195 * Makefile.am (LDADDS): Add $(MATH_LIB).
1197 2001-04-18 Havoc Pennington <hp@redhat.com>
1199 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1202 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1204 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1205 so we don't try to get <gtk/gtkobject.h> from standard search
1208 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1209 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1210 take gdk-pixbuf-marshal.h out of _la sources.
1212 2001-03-19 Tor Lillqvist <tml@iki.fi>
1214 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1216 * gdk_pixbuf.def: Update.
1218 * pixbufloader_*.def: Just export the fill_vtable functions now.
1220 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1222 * make-inline-pixbuf.c (main): Added logic to remove output when
1225 2001-03-14 Havoc Pennington <hp@redhat.com>
1227 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1228 from gdk-pixbuf-marshal.h, fixes parallel makes.
1230 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1232 * test-gdk-pixbuf.c: fixed includes.
1234 2001-02-18 Havoc Pennington <hp@pobox.com>
1236 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1237 (gdk_pixbuf_get_named_module): prepend underscore
1238 (gdk_pixbuf_get_module): prepend underscore
1240 2001-02-19 Havoc Pennington <hp@redhat.com>
1242 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1244 2001-02-17 Havoc Pennington <hp@pobox.com>
1246 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1248 2001-02-07 Alexander Larsson <alexl@redhat.com>
1250 * io-xpm.c (free_buffer):
1251 Use g_free, since the buffer is allocated with g_try_alloc().
1253 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1255 * gdk-pixbuf-data.c: Fixes a minor typo.
1257 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1259 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1260 we finally need the gobject->gruntime rename.
1262 * *.c: scratched calls to g_type_init(), there's simply no point in
1263 doing that, use gtk_init().
1265 2001-02-01 Havoc Pennington <hp@pobox.com>
1267 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1268 in struct to "priv" for C++
1270 2001-01-31 Havoc Pennington <hp@pobox.com>
1272 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1274 2001-01-26 Havoc Pennington <hp@redhat.com>
1276 * gdk-pixbuf-io.c (mname): fix included modules case.
1278 2001-01-22 Havoc Pennington <hp@redhat.com>
1280 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1281 from gdk_pixbuf_load_module
1283 2001-01-22 Havoc Pennington <hp@redhat.com>
1285 * Makefile.am: Add built marshaller files to support
1286 GdkPixbufLoader signals
1288 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1289 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1290 module location, rather than acting as a fallback, because we are
1291 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1293 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1295 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1296 from gtk, and add error to close(), because stop_load may do
1297 parsing of the image.
1299 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1301 * io-*.c: make individual operations static, and add fill_vtable
1302 functions which are exported. Fix the collection of type warnings
1303 that surfaced, including a number of functions that didn't
1304 properly take a GError and some that weren't
1305 const-correct. Involved adding error handling for a few loaders.
1307 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1309 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1310 a function that fills in the GdkPixbufModule vtable, instead of
1311 looking up all the image functions individually; this means we
1312 can get type safety within modules for the loader functions.
1313 Also it means you don't have to keep the statically compiled and
1314 GModule versions in sync.
1316 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1318 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1320 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1322 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1325 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1327 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1330 2001-01-20 John Harper <jsh@eazel.com>
1332 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1333 collision between Xlib's RdBitF.c and io-tiff.c
1335 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1338 [ merged from stable gdk-pixbuf module. Untested, but it
1339 compiles, and works fine in the stable module ]
1341 2001-01-18 Tor Lillqvist <tml@iki.fi>
1343 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1344 g_win32_get_package_installation_subdirectory() function. No need
1345 to include windows.h.
1346 (gtk_win32_get_installation_directory): Remove this then.
1348 2001-01-01 Havoc Pennington <hp@redhat.com>
1350 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
1351 @LIBTOOL_EXPORT_OPTIONS@
1353 2000-12-30 Tor Lillqvist <tml@iki.fi>
1355 * gdk_pixbuf.def: Update.
1357 2000-12-16 Havoc Pennington <hp@pobox.com>
1359 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1360 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1361 (gdk_pixbuf_frame_copy): new function
1362 (gdk_pixbuf_frame_free): new function
1363 (gdk_pixbuf_frame_get_type): new function
1364 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
1366 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
1368 * Makefile.am: Add -avoid-version for all modules.
1370 2000-11-13 Havoc Pennington <hp@redhat.com>
1372 * io-png.c (png_simple_error_callback): fix error message to not
1373 say "save" since it's used for loading
1375 2000-11-11 Hans Breuer <Hans@Breuer.Org>
1377 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1378 contained image handlers (!USE_G_MODULE). Files to save should
1379 be opened in binary mode, fopen(s, "wb").
1381 * io-xpm.c : added HAVE_UNISTD_H condition
1383 2000-11-11 Tor Lillqvist <tml@iki.fi>
1385 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1387 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1388 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1389 mktemp() and open()).
1391 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1393 2000-11-01 Havoc Pennington <hp@pobox.com>
1395 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1396 a pixbuf pointing to a subregion of another pixbuf.
1398 2000-10-16 Tor Lillqvist <tml@iki.fi>
1400 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1402 2000-10-16 Havoc Pennington <hp@redhat.com>
1404 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1405 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1406 add error reporting here also
1408 * make-inline-pixbuf.c (main): use GError
1410 * io-xpm.c: include unistd.h
1412 * gdk-pixbuf-util.c: include string.h
1414 * io-*.c: add error reporting
1416 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
1419 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
1421 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1424 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1425 a G_FILE_ERROR if we fail to write or close the file.
1427 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1428 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1429 the GError naming rules. Add GError** to load functions.
1431 2000-10-06 Havoc Pennington <hp@redhat.com>
1433 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1435 2000-10-06 Havoc Pennington <hp@redhat.com>

1463 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
1465 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
1466 last nights code was still "broken". Should now properly handle
1467 all error conditions gracefully.
1469 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
1471 * gdk-pixbuf/io-pnm.c: Rewrote.

1475 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
1476 the correct dest offset.
1478 2000-08-25 Federico Mena Quintero <federico@helixcode.com>
1480 * gdk-pixbuf/io-xpm.c: #include <unistd.h>
1482 2000-08-05 Larry Ewing <lewing@helixcode.com>
1484 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
1486 * gdk-pixbuf/io-xpm.c: same as above.
1488 2000-07-26 Michael Meeks <michael@helixcode.com>
1490 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
1493 2000-07-21 Larry Ewing <lewing@helixcode.com>
1495 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
1496 xpm at least supports the progressive interface like the one in
1497 io-tiff.c. This should be reimplemented as an actual progressive
1500 2000-07-19 Jonathan Blandford <jrb@redhat.com>
1502 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
1503 make it look better.

1515 2000-10-06 Havoc Pennington <hp@redhat.com>
1517 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
1518 consistent with gdk_pixbuf_loader_new_with_type().
1519 Return runtime error if a module is missing.
1521 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
1523 2000-10-05 Havoc Pennington <hp@redhat.com>
1525 Pixbuf saving, patch from David Welton.
1527 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS

1549 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
1550 all three of these files are the JPEG image loader. (From
1553 2000-10-03 Tor Lillqvist <tml@iki.fi>
1555 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
1556 gdk-pixbuf's version number in the rule for makefile.mingw itself.
1558 * gdk_pixbuf.def: Add new entry points.
1560 2000-09-26 Havoc Pennington <hp@redhat.com>
1562 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
1563 function here, instead of putting it in a private GTK+ file.
1565 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
1566 enum here for the known formats of inlined pixbufs.
1567 Also, #define our file magic here.
1569 2000-06-23 Havoc Pennington <hp@redhat.com>
1571 * make-inline-pixbuf.c: Small program that creates C variable
1572 declarations of inline pixbuf data. This can be read
1573 by gdk_pixbuf_new_from_inline.
1575 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
1576 inline pixbuf data and create a pixbuf from it.
1578 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1580 2000-09-07 Tor Lillqvist <tml@iki.fi>
1582 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1585 2000-08-12 Tor Lillqvist <tml@iki.fi>
1587 * gdk_pixbuf.def: Add missing entry point.
1589 2000-08-10 Havoc Pennington <hp@redhat.com>
1591 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1592 (s/pixbuf_/pixbufloader_)
1594 2000-08-02 Tor Lillqvist <tml@iki.fi>
1600 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1602 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1603 one. Fix names of DLLs to have '-' instead of '_'.
1605 2000-07-31 Elliot Lee <sopwith@redhat.com>
1606 * io-wbmp.c: Some bug fixes - now tested to work.
1608 2000-07-27 Elliot Lee <sopwith@redhat.com>
1610 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1611 gdk_pixbuf_get_named_module() function to facilitate above change
1612 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1613 Implement loader for WBMP format.
1614 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1616 2000-07-23 Tor Lillqvist <tml@iki.fi>
1621 * pixops/makefile.mingw.in
1622 * pixbuf_*.def: New files.
1625 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1627 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1628 New function, to get the GTK+ installation directory from
1629 the Windows Registry, where the installation program
1630 for whatever software includes GTK+ has stored it.
1632 Used to avoid having hardcoding the directory where to look for
1633 loaders. This function is needed by gtk, too, so it should
1634 really be just in one place. Maybe a small static library
1635 one level up from here?
1637 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1638 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1639 Open file in binary mode. This *is* standard C. (No-op on Unix,
1642 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1644 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1645 mktemp() and open().
1646 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1648 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1649 pseudo-op. Conditionalise on __MINGW32__, but probably
1650 should conditionalise on Gas version instead? Or could we
1651 do without .type on all systems?
1653 * pixops/timescale.c: Use g_get_current_time()
1654 instead of gettimeofday().
1656 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1658 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1660 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1662 * gdk-pixbuf.c: Add <string.h> include.
1664 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1666 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1667 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1668 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1669 use g_object_new() instead of g_type_create_instance() which
1670 is a private function for fundamental type implementations.
1672 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1674 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1675 soname scheme for gdk-pixbuf.
1677 2000-06-21 Havoc Pennington <hp@pobox.com>
1679 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1680 (i.e. derivation is not allowed, and there are no virtual methods
1682 (gdk_pixbuf_preinit): Call g_type_init() here.
1683 (gdk_pixbuf_init): Add a user-friendly init function, for users
1684 of standalone gdk-pixbuf
1686 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1687 way GdkPixbufAnimation was done.
1689 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1690 gdk_pixbuf_finalize() from API, since these are broken and don't
1691 make sense with new GObject stuff.
1693 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1695 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1696 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1699 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1701 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1702 so I needed something to warm my thighs. Running plain infinite
1703 loops on your laptop to make it hot is not very much fun. A demo
1704 of the gdk-pixbuf scaling functions is way better, and looks
1707 * configure.in (AC_OUTPUT): Added the demo Makefile.
1709 * Makefile.am (SUBDIRS): Added the demo directory.
1711 2000-06-09 Larry Ewing <lewing@helixcode.com>
1713 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1714 setjmp for the png error handler. It seems setting the error
1715 handling functions does not avoid the jump, and so not calling
1716 setjmp was causing the incremental loader to jump into lala land.
1717 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1718 not sure this one is actually required but the docs say it must be
1719 set for every call to a png_* function.
1720 Also changed the comment to reflect the fact that setting the
1721 error handlers does _not_ avoid the longjmp.
1723 2000-06-06 Larry Ewing <lewing@helixcode.com>
1725 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1726 take frame offest into account when trying to calculate the
1727 animation bbox. Also set the width to the width not the height.
1728 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1729 calculate bbox because now we finally have all the offset
1730 information for each frame.
1732 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1734 * configure.in: add some gtk parameters to the
1735 GDK_PIXBUF_LIBÃ�²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1736 fight in my crusade for strange prefix compile...
1738 2000-05-30 Not Zed <NotZed@HelixCode.com>
1740 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
1741 Initialise the error handler exit routine to our own. Note this
1742 means that every function that accesses the jpeg lib on this
1743 object MUST do a setjmp.
1744 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
1745 lib for handling fatal error.
1746 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
1747 your applications dont quit if there's a jpeg error!
1749 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
1751 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
1752 from Frank de Lange <frank@unternet.org>.
1754 2000-05-09 Darin Adler <darin@eazel.com>
1756 * gdk-pixbuf/test-gdk-pixbuf.c:
1757 Fixed includes to get rid of accidental GNOME dependency.
1759 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
1760 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
1762 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
1764 * configure.in: Bumped version number to 0.8.0.
1766 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
1767 file was not being distributed.
1769 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
1771 2000-05-09 Darin Adler <darin@eazel.com>
1773 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
1774 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
1775 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
1776 formats to 32-bit formats to re-use the high bits of the color values
1777 so that white maps to full white.
1779 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
1781 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
1782 detailed information about the structure and algorithms
1783 of pixops so people can fix it instead of breaking it.
1785 2000-05-04 Darin Adler <darin@eazel.com>
1787 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
1788 (composite_pixel), (composite_line):
1789 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
1790 Now that Owen explained the algorithm, I think I implemented it
1791 right for the cases where the destination pixbuf is not opaque.
1792 The test does seem to confirm it.
1794 2000-05-04 Darin Adler <darin@eazel.com>
1796 * gdk-pixbuf/.cvsignore:
1797 * gdk-pixbuf/Makefile.am:
1798 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
1799 (load_pixel), (simple_composite_test_one),
1800 (simple_composite_test_one_type), (simple_composite_test), (main):
1801 Added some tests of composite to highlight problems in the old
1802 implementation. These tests run without any user interaction.
1803 Just do "make check".
1805 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
1806 (composite_pixel), (composite_line): Fix composite to do a textbook
1807 "A over B" composite. This was clearly the intent, and it was easy
1808 to fix the code to do it. (Note to those that read my earlier tries
1809 at a patch; this version fixes typos that were present in all
1810 my patch attempts. I checked the final version by adding more tests.)
1812 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
1814 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
1815 offset y coordinate accordining to render_y0.
1817 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
1820 2000-04-22 James Henstridge <james@daa.com.au>
1822 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
1823 package to the devel package. The only file installed in bin is
1824 gdk-pixbuf-config, which belongs in -devel. This should allow having
1825 multiple versions of the main gdk-pixbuf package installed.
1827 2000-04-17 Karl Eichwalder <ke@suse.de>
1829 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
1830 Reported by Jens Finke.
1832 2000-04-14 Tomasz KÃ�³opczko <kloczek@pld.org.pl>
1834 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
1835 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
1837 2000-04-13 James Henstridge <james@daa.com.au>
1839 * configure.in: when performing the configure check to see if
1840 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
1841 rather than the other way round. Also, call AC_MSG_RESULT in the
1842 even that dynamic modules were not supported.
1844 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
1846 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
1847 hook to the last unref operation.
1849 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
1850 function to set the last unref handler for a pixbuf.
1851 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
1852 It calls the pixbuf's destroy notification function and frees the
1853 GdkPixbuf structure itself.
1854 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
1857 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
1858 for the last unref handler and its user data.
1860 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
1861 g_new0() to allocate the pixbuf.
1863 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
1864 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
1865 was not specifying the `frame' argument.
1867 * gdk-pixbuf/gdk-pixbuf-animation.c
1868 (gdk_pixbuf_animation_get_width): Fixed docstring.
1869 (gdk_pixbuf_animation_get_height): Likewise.
1870 (gdk_pixbuf_animation_get_num_frames): Likewise.
1871 (gdk_pixbuf_animation_get_frames): Likewise.
1873 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1876 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1878 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1880 * doc/tmpl/refcounting.sgml: Updated with the information about
1881 the last unref handler.
1883 * doc/tmpl/*.sgml: Markup tweaks.
1885 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1886 update the libtool version number for libgnomecanvaspixbuf as
1888 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
1889 as well, or the old ones won't work with the new stuff. Also,
1890 renamed the modules as follows.
1892 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
1893 modules are called "libpixbufloader-<format>.so" instead of
1894 "libpixbuf-<format>.so". They needed renaming so that the new
1895 loaders won't overwrite the old ones; even with the versioning
1896 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
1899 2000-04-12 Paolo Molaro <lupus@debian.org>
1901 * .cvsignore, src/.cvsignore: shut up cvs.
1903 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
1905 Most of this patch is based on a patch by Havoc Pennington
1906 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
1907 remove the libart dependency.
1909 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
1910 (GdkColorspace): New enum that for now only contains
1912 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
1913 notification function.
1914 (GdkInterpType): New num with interpolation types.
1916 * *.[ch]: Replace the libart stuff with our own stuff.
1918 * pixops/*.[ch]: Likewise.
1920 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
1921 declarations of the GdkPixbuf structures.
1923 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
1925 (gdk_pixbuf_get_format): Constify.
1926 (gdk_pixbuf_get_n_channels): Constify.
1927 (gdk_pixbuf_get_has_alpha): Constify.
1928 (gdk_pixbuf_get_bits_per_sample): Constify.
1929 (gdk_pixbuf_get_pixels): Constify.
1930 (gdk_pixbuf_get_width): Constify.
1931 (gdk_pixbuf_get_height): Constify.
1932 (gdk_pixbuf_get_rowstride): Constify.
1934 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
1937 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
1938 bits_per_sample argument; currently only 8 bits per sample are
1941 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
1943 (gdk_pixbuf_frame_get_x_offset): New accessor.
1944 (gdk_pixbuf_frame_get_y_offset): New accessor.
1945 (gdk_pixbuf_frame_get_delay_time): New accessor.
1946 (gdk_pixbuf_frame_get_action): New accessor.
1948 * gdk-pixbuf/gdk-pixbuf-render.c
1949 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
1950 mask rectangle for pixbufs without an alpha channel, set the
1951 *mask_return to NULL.
1953 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
1955 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
1957 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
1958 preconditions. Maybe we should also check for the colorspace,
1959 bits per pixel, and such.
1960 (gdk_pixbuf_composite): Likewise.
1961 (gdk_pixbuf_composite_color): Likewise.
1962 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
1963 cannot allocate the new pixbuf.
1964 (gdk_pixbuf_composite_color_simple): Likewise.
1966 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
1967 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
1970 * gdk-pixbuf/io-bmp.c: Fix includes.
1972 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
1977 * configure.in: Removed checks for libart.
1979 * gdk-pixbuf/Makefile.am: Removed references to libart.
1980 (noinst_HEADERS): Added gdk-pixbuf-private.h.
1982 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
1983 the version number of the libtool library to indicate that this
1984 definitely is not compatible with the old usage. I know you love
1987 * configure.in: Bumped version number to 0.7.0.
1991 * gdk-pixbuf-config.in (--libs): We no longer require libart.
1993 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
1995 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
1997 2000-04-06 Jonathan Blandford <jrb@redhat.com>
1999 * gdk-pixbuf/testanimation.c (main): add more info to the
2000 testanimation frames.
2002 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
2004 * gdk-pixbuf/gdk-pixbuf-animation.c
2005 (gdk_pixbuf_animation_get_width): New accessor function.

2007 (gdk_pixbuf_animation_get_num_frames): New accessor function.
2008 (gdk_pixbuf_animation_get_frames): New accessor function.
2010 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
2012 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
2013 is private information, and the art_pixbuf will go away soon.
2015 2000-03-31 Mark Crichton <crichton@gimp.org>
2017 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
2018 and gdk_pixbuf_get_artpixbuf accessor functions.
2020 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
2022 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
2023 gboolean instead of int.
2025 2000-03-29 Radek Doulik <rodo@helixcode.com>
2027 * gdk-pixbuf/gdk-pixbuf-animation.c
2028 (gdk_pixbuf_animation_new_from_file): same as below
2030 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
2031 height in GdkPixbufAnimation
2033 2000-03-28 Radek Doulik <rodo@helixcode.com>
2035 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
2036 context->frame_done_func and context->anim_done_func to make
2037 progressive animation loading work
2039 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
2040 added priv->pixbuf = NULL as pixbuf is now in frame (and to make
2041 gdk_pixbuf_loader_prepare happy)
2042 (gdk_pixbuf_loader_frame_done): update animation bbox
2044 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
2047 2000-03-27 Radek Doulik <rodo@helixcode.com>
2049 * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
2050 instead of width and height
2052 2000-03-27 Owen Taylor <otaylor@redhat.com>
2054 * gdk-pixbuf/pixops/pixops.c: Fix problem with
2055 precendence of >> and & which was keeping composite_color
2056 from working with non-gray images.
2058 2000-03-08 Jonathan Blandford <jrb@redhat.com>
2060 * gdk-pixbuf/io-gif.c (gdk_pixbuf__gif_image_load): free the context.
2061 (gdk_pixbuf__gif_image_load_animation): free the context.
2063 2000-03-06 Arjan van de Ven <arjan@fenrus.demon.nl>
2065 * gdk-pixbuf/io-bmp.c: Fixed to pointer-bugs and a
2066 mis-interpretation of the Microsoft documentation. Now
2067 it can load .BMP files that are not generated by The Gimp
2070 2000-03-01 Mark Crichton <crichton@gimp.org>
2072 * configure.in: Added BUILD_CANVAS_ITEM stuff to (finally)
2073 fix the last auto* build bug (where we have libart, but no
2076 * gdk-pixbuf/Makefile.am: Same.
2078 2000-02-28 Matt Wilson <msw@redhat.com>
2080 * gdk-pixbuf/gdk-pixbuf-drawable.c: s/unsigned long/guint32/g,
2081 s/unsigned short/guint16/g, s/unsigned char/guint8/g
2083 2000-02-26 Federico Mena Quintero <federico@helixcode.com>
2085 * README: We don't require libgif/ungif nor libXpm.
2087 * NEWS: This was outdated, so updated it.
2089 2000-02-25 Federico Mena Quintero <federico@helixcode.com>
2091 * gdk-pixbuf.m4: Use the correct name for
2092 gdk-pixbuf/gdk-pixbuf.h. Thanks to Jacob Berkman for pointing
2095 2000-02-21 Federico Mena Quintero <federico@helixcode.com>
2097 * configure.in (GDK_PIXBUF_MINOR): Bumped version number to 0.6.0.
2099 * doc/compiling.sgml: New appendix documenting the gdk-pixbuf
2100 library's particular options to configure.in.
2102 * doc/gdk-pixbuf.sgml: Include compiling.sgml appendix via an
2105 * doc/Makefile.am (gdk-pixbuf.html): Added compiling.sgml.
2107 * gdk-pixbuf/io-ico.c (gdk_pixbuf__ico_image_load_increment):
2108 Fixed typo in prototype name.
2110 * configure.in: Changed duplicated AC_MSG_CHECKING message to
2111 something more meaningful; now it is "checking whether dynamic
2114 * gdk-pixbuf/pixops/Makefile.am (noinst_PROGRAMS): Do not install
2115 the timescale program.
2117 Integrated Miguel de Icaza's <miguel@gnu.org> patch for optionally
2118 creating a single static library with all the image format modules
2121 2000-02-20 Miguel de Icaza <miguel@gnu.org>

2124 (gdk_pixbuf__xpm_image_load_xpm_data): Add prefix.
2126 * gdk-pixbuf/io-tiff.c (gdk_pixbuf__tiff_image_load_real): Add prefix.

2487 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
2488 animation functions here.
2489 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
2490 animation if the loader does not support multiframe loading and
2491 the single-frame load returned NULL. Check that the filename is
2492 not NULL. Updated inline documentation.

2494 (gdk_pixbuf_animation_unref): New function.
2495 Removed gdk_pixbuf_animation_destroy() in favor of reference

2531 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
2532 set to NULL here (specifically context->animation) was not being
2533 set to NULL. use g_new0() to alloc the struct.
2535 1999-12-20 Jonathan Blandford <jrb@redhat.com>
2537 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2538 correctly. Progressive loading needs some work, but that all
2539 needs doing from the gdk-pixbuf-loader end, not here.
2541 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2543 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2544 moved the file here. It seems natural to put this function here,
2545 as that's where the gdk_pixbuf_new_from_file function is, but it's
2546 still a little convoluted. The source files might be played with
2549 1999-12-14 Jonathan Blandford <jrb@redhat.com>

2563 * gdk-pixbuf/gnome-canvas-pixbuf.c
2564 (gnome_canvas_pixbuf_class_init): Renamed arguments to
2565 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for

2595 Filled in body of function.
2596 (rgbconvert): Added GdkColormap parameter, and to all conversion
2598 (convert_real_slow): New function - should convert ANY visual/data
2599 format properly, but it aint fast. Used as a fallback when an
2600 optimised routine wont match.
2601 (rgbconvert): Do very specific tests on the data format to verify
2602 properly if the optimised version will do, otherwise use the
2603 fallback function for all other data formats.
2605 * gdk-pixbuf/Makefile.am: Re-enabled building of
2606 textpixbuf-drawable.
2608 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
2609 gdk_pixbuf_get_from_drawable().
2611 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
2613 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red

2620 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2621 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2622 checks and API definition. The body needs filling in and it needs
2623 to do the Right Thing(tm) for pixmaps plus the given colormap and
2624 windows and their own colormaps.
2626 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2627 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.

2664 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2665 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2666 want, send me a patch to do the conditional stuff properly.

2693 1999-12-03 Federico Mena Quintero <federico@redhat.com>
2695 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):

2701 explain this function better.
2703 1999-12-02 Federico Mena Quintero <federico@redhat.com>
2705 Source files moved from src/ to gdk-pixbuf/, to be consistent with

2780 1999-11-29 Owen Taylor <otaylor@redhat.com>
2782 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
2783 Keep the mask around until after we draw ... since
2784 the GC changes aren't flushed to the X server until we
2785 draw, destroying it before that may result in BadPixmap
2788 1999-11-30 Havoc Pennington <hp@pobox.com>
2790 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
2792 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
2794 1999-11-29 Federico Mena Quintero <federico@redhat.com>
2796 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
2797 should be made conditional, not blindly commented out.
2799 1999-11-29 Jonathan Blandford <jrb@redhat.com>
2801 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
2802 handle .ico files. Cool.
2804 1999-11-24 Jonathan Blandford <jrb@redhat.com>
2806 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
2809 1999-11-24 James Henstridge <james@daa.com.au>
2811 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
2812 top builddir rather than src. This still builds fine, and does not
2813 get gtk-doc into an infinite loop when trying to find all the source
2816 1999-11-23 Jonathan Blandford <jrb@redhat.com>
2818 * Removed #PRAGMA } from headers. Also, make compile if you don't
2819 have it installed, already.
2821 1999-11-22 Federico Mena Quintero <federico@redhat.com>
2823 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
2824 temporary buffer to the size of the interesction of the bounding
2825 box and the expose area, not the whole expose area. This speeds
2828 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
2829 not paint black on the mask, since we already cleared it in a
2830 single gdk_draw_rectangle() operation.
2832 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
2834 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
2836 1999-11-22 Havoc Pennington <hp@pobox.com>
2838 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
2839 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
2840 dependencies to LIBADD variables for loadable modules. Necessary
2841 for a Java dynamic loading thing to be able to figure it out.
2843 1999-11-22 Havoc Pennington <hp@pobox.com>
2845 * src/io-png.c (image_load_increment): Call the update_area
2846 callback depending on the number of rows loaded in this increment.
2848 * src/testpixbuf.c (main): slow down the progressive load demo
2850 1999-11-16 Havoc Pennington <hp@pobox.com>
2852 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
2854 1999-11-22 Jonathan Blandford <jrb@redhat.com>
2856 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
2857 for srcdir != buildir != . Beats me why; I can't figure it out.
2858 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
2860 1999-11-21 Jonathan Blandford <jrb@redhat.com>
2862 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
2863 <arjan@fenrus.demon.nl>
2865 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2867 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
2868 Rework/reorder of the code. Each case has been separated into
2869 another function; its big but it should be quick.
2870 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
2871 opaque alpha information. Not all depths/formats have been
2872 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
2874 1999-11-17 Larry Ewing <lewing@gimp.org>
2876 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2877 implement the bounds method correctly.
2878 (compute_viewport_affine): compute the affine need to fit the
2879 image within the viewport given by the args.
2880 (compute_render_affine): call compute_viewport_affine.
2882 1999-11-16 Havoc Pennington <hp@pobox.com>
2884 * src/gdk-pixbuf-drawable.h: Use includes from the current
2885 directory, not the system directory.
2887 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
2889 * src/testpixbuf-drawable.c: use includes from the current directory
2890 rather then from the system include directory as gdk-pixbuf
2891 includes are not yet installed when this is compiled.
2893 1999-11-13 Cody Russell <bratsche@dfw.net>
2894 * src/testpixbuf-drawable.c: Added a test program for drawable
2897 * src/Makefile.am: Build testpixbuf-drawable.
2899 1999-11-12 Cody Russell <bratsche@dfw.net>
2901 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.

2914 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
2917 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
2918 correctly. Patch from Arjan to do so.
2920 1999-11-10 Michael Fulbright <drmike@redhat.com>
2922 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
2925 * src/testpixbuf.c: Added final queued draw when done loading image.
2927 1999-11-10 Jonathan Blandford <jrb@redhat.com>
2929 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
2932 1999-11-10 Federico Mena Quintero <federico@redhat.com>
2934 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
2937 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2939 * src/io-png.c: Fixed some incompatible pointer initializations.
2941 * src/io-jpeg.c (image_load_increment): Remove unused variable.
2943 1999-11-09 Michael Fulbright <drmike@redhat.com>
2945 * src/testpixbuf.c: Fixed it to use timeout to read from file
2946 for progressive loading. Set TBF_KBPS=n, where n is the number of
2947 kilobytes/second to simulate in downloading. n has to be an integer.
2949 * src/io-jpeg.c: Slight cosmetic cleanup.
2951 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
2952 PBM loading has a similar problem and will address tomorrow.
2954 1999-11-09 Havoc Pennington <hp@pobox.com>
2956 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
2957 gdk-pixbuf-drawable stuff.
2959 1999-11-09 Federico Mena Quintero <federico@redhat.com>
2961 * configure.in: Bumped version number to 0.4.
2963 1999-11-09 Michael Fulbright <drmike@redhat.com>
2965 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
2966 all types of PNM files now.
2968 * src/io-jpeg.c (image_load_increment): Figured out problem with
2969 loading Progressive JPEG's progressively (say that 10 times fast).
2970 Currently for Progressive JPEG's the entire image is loaded before
2971 it is displayed. libjpeg supports a fancier mechanism which I may
2974 With these changes all JPEG formats appear to load properly for me.
2976 1999-11-08 Jonathan Blandford <jrb@redhat.com>
2978 * src/io-ras.c (image_load_increment): Final patch from Arjan.
2979 Seems to do progressive loading.
2981 1999-11-08 Michael Fulbright <drmike@redhat.com>
2983 * src/io-pnm.c image_load (): Fixed so we do not create a separate
2984 pixel buffer when reading in image - we reuse the pixel data in
2985 the GdkPixbuf structure instead.
2987 1999-11-08 Michael Fulbright <drmike@redhat.com>
2989 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
2990 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
2991 I can't seem to find a utility to convert into this format.
2992 Next is to add progressive loading support for the PNM format.
2994 1999-11-07 Federico Mena Quintero <federico@redhat.com>
2996 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
2997 of the width, height, x, and y setting and pixels arguments.
2999 1999-11-05 Jonathan Blandford <jrb@redhat.com>

3004 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
3006 * src/io-ras.c (image_load): new file from Arjan van de Ven
3007 <arjan@fenrus.demon.nl> to begin the ras loader.
3009 1999-11-05 Federico Mena Quintero <federico@redhat.com>
3011 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
3012 for internal use only.
3014 * doc/gdk-pixbuf.sgml: Likewise.
3016 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
3018 1999-11-05 Michael Fulbright <drmike@redhat.com>

3028 1999-11-04 Michael Fulbright <drmike@redhat.com>
3030 * src/io-jpeg.c: Prettied up code slightly.
3031 * src/io-pnm.c: Start of pnm loader (from file and progressively).
3032 Doesn't do much yet (will finish tomorrow).
3033 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
3035 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3037 * doc/tmpl/rendering.sgml: Populated.
3039 * doc/Makefile.am: Added the template files.
3041 1999-11-04 Havoc Pennington <hp@pobox.com>
3043 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
3044 docs, explain what a dither offset is for.
3045 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3046 this function vs. gdk_pixbuf_render_to_drawable().
3048 1999-11-04 Havoc Pennington <hp@pobox.com>
3050 * configure.in: Use libart-config correctly; find gnome-config
3051 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3054 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3057 Patch untested in the inside-gnome-libs case, I need to commit
3058 then check out to the gnome-libs I'm using.
3060 1999-11-04 Michael Fulbright <drmike@redhat.com>
3062 * src/io-jpeg.c (image_begin_load): Add update_func callback.
3063 * src/io-jpeg.c (image_load_increment): Call updated callback when
3064 new graphic data decoded.
3066 1999-11-04 Jonathan Blandford <jrb@redhat.com>

3108 * src/io-jpeg.c (image_load_increment): Further removal of
3109 bugginess in local buffering code. Handles grayscale jpegs
3112 * src/io-jpeg.c (image_load_stop): Was freeing local context
3113 for jpeg library before calling jpeg_decompres_finish ().
3115 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3117 * src/io-gif.c (image_load_increment): now handle arbitrary buffer

3140 render_affine calculation for x,y offsets.
3141 (gnome_canvas_pixbuf_set_arg): add x,y args.
3142 (gnome_canvas_pixbuf_get_arg): add x,y args.
3143 (recompute_bounding_box): simply code using ArtDrect and the
3144 render_affine. Removed compute_xform_vectors as it was no longer
3147 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3149 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
3150 doofus. Return a distance, not a boolean, for opaque images.
3152 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
3153 rounding of bounding box coordinates.
3154 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
3155 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
3157 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3159 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
3161 1999-11-03 Michael Fulbright <drmike@redhat.com>
3163 * src/io-jpg.c (image_load_increment): Fixed code which moved
3164 buffer around as new data comes in to work properly. JPEG progressive
3165 loading should be working now except for grayscale JPEG's, which I
3166 will look into next.
3168 1999-11-03 <sopwith@redhat.com>
3169 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
3170 Also put dot printing back in.
3172 1999-11-03 <jrb@redhat.com>
3174 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
3177 1999-11-02 Cody Russell <bratsche@dfw.net>
3178 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
3179 if part of the requested image is offscreen, rather than clipping
3182 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3184 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
3185 for interlacing and progressive loading.
3187 1999-11-02 Cody Russell <bratsche@dfw.net>
3188 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
3189 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
3191 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3193 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
3194 It's a little slow though. )-:

3202 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
3203 Implemented the ::point() method. We do a simple containment test
3204 instead of a full distance calculation since the canvas is going
3205 to change to that scheme, anyways.
3207 1999-11-02 Elliot Lee <sopwith@redhat.com>
3209 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
3210 that are read from the input file.
3212 1999-11-02 Larry Ewing <lewing@gimp.org>
3214 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa

3219 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3221 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3222 affine computation code from ::draw() to here, since it is needed
3223 by ::point() as well.
3225 1999-11-02 Elliot Lee <sopwith@redhat.com>
3227 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3228 three functions, and eliminate duplication of code from write()
3229 and close(). Also fix bug where the 128-byte header was being
3232 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3233 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3234 bounding box computation.
3236 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3238 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3239 Drawing affines seem to work. Bounding box is fubared. ::point()
3240 is not implemented. This is a work in progress.
3242 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3245 * configure.in: Sigh. We need to link in libgnomeui for the
3246 canvas stuff. This mess will disappear when gdk-pixbuf gets
3247 folded into gnome-libs.
3249 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3251 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3252 the right size, at a minimum, even if the image is squished and
3254 (ReadImage): lets get the offset right. This will let transparent
3257 1999-10-29 Michael Fulbright <drmike@redhat.com>
3259 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3260 image width was not a multiple of 4 - always use the
3261 gdk_pixbuf rowstride to increment pointers!
3263 1999-10-29 Michael Fulbright <drmike@redhat.com>
3265 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3266 Currently does not handle either progressive jpeg files (jpeg
3267 files with multiple scans at different quality settings), but
3268 I plan on adding this support soon. These are fairly rare in
3269 my experience, so it shouldn't slow people down too much.
3270 Grayscale jpegs also don't work but that should be easy to fix.
3272 1999-10-29 Michael Fulbright <drmike@redhat.com>
3274 * src/testpixbuf.c: Added title to windows so you can identify
3275 progressive and file windows.
3277 1999-10-29 Michael Fulbright <drmike@redhat.com>
3279 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3280 load the image handler when we determine the image type.
3282 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3283 previously static function load_image_handler () to
3284 a public function gdk_pixbuf_load_module (). It is needed in
3285 gdk-pixbuf-loader.c to load image handler modules. This function
3286 is different from gdk_pixbuf_get_module (), which only returns
3287 a reference to the required handler, because it actually loads
3288 the handler into memory. Both actions should possibly be combined
3289 in a convenience function since one w/o the other doesn't seem to
3292 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3294 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a

3299 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3300 function to render a portion of a pixbuf to a drawable. Ignores
3301 alpha information and takes in a GC.
3302 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3303 portion of a pixbuf to a drawable. It automatically creates a GC
3304 and a clipping mask for alpha pixbufs.
3306 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3308 * src/gdk-pixbuf.h: turned convenience macros into convenience
3309 functions so some error checking could be added.
3311 * src/io-tiff.c (image_load_increment): started work on the tiff
3312 non-incremental loader.
3313 (image_begin_load): Finished the incremental loader.

3320 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3322 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3323 function to threshold a pixbuf's alpha channel into a bitmap.
3325 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3326 contemplate future extensions to ArtPixBuf's formats.
3328 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3330 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3331 macros to fetch the ArtPixBuf's fields.
3333 1999-10-27 Havoc Pennington <hp@pobox.com>

3338 code into separate function
3339 (png_info_callback): Use setup_png_transformations
3341 1999-10-27 Havoc Pennington <hp@pobox.com>
3343 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3344 properly whether the XPM module has already been loaded
3345 (gdk_pixbuf_new_from_file): Check properly if loader module
3346 was already loaded (was checking if load symbol was present
3347 in order to decide whether to re-load; should check module !=
3348 NULL, then load != NULL)
3349 (image_handler_load): Check in present working directory,
3350 makes it easier to debug for now
3351 (file_formats): This array initializer was seriously on crack,
3352 was assigning a function pointer to a GModule*
3354 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
3356 1999-10-27 Havoc Pennington <hp@pobox.com>

3362 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3364 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
3365 GdkPixbufLoader, not a GtkObject.
3366 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
3367 (gdk_pixbuf_loader_get_type): Documented.
3368 (gdk_pixbuf_loader_class_init): Initialize the parent class
3370 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
3371 class destroy function.
3372 (gdk_pixbuf_loader_new): Documented.
3373 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3375 (gdk_pixbuf_loader_write): Use size_t for count.
3377 1999-10-27 Michael Fulbright <drmike@redhat.com>
3379 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3380 logic so we only try to close loader if it wasn't previously closed.
3382 1999-10-27 Michael Fulbright <drmike@redhat.com>
3384 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of
3385 pixbuf_loader properly initialized.

3411 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3413 1999-10-22 Havoc Pennington <hp@pobox.com>
3415 * src/io-xpm.c (mem_buffer): Clean up stupid
3416 increment-inside-array-dereference thing
3418 * src/testpixbuf.c: Add XPM data tests.
3420 * src/io-xpm.c: Make the XPM data buffer const, fix const
3421 correctness throughout the code.
3423 1999-10-22 Havoc Pennington <hp@pobox.com>
3425 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()
3427 1999-10-22 Havoc Pennington <hp@pobox.com>
3429 * src/io-xpm.c (image_load_xpm_data): Export this symbol for
3430 loading an XPM from memory.

3433 function, loads pixbuf from xpm data
3434 (image_handler_load): Add g_return_if_fail() to ensure the same
3435 module isn't loaded twice. Add g_module_symbol() to scan for XPM
3438 1999-10-22 Federico Mena Quintero <federico@redhat.com>
3440 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3441 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
3442 buffers; the rows can be read in directly into the main pixel
3445 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3447 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
3449 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3451 * configure.in: Bumped version number to 0.3.
3453 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
3454 version number for the library.
3456 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3458 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
3459 all memory management of the buffer is done by libart.
3461 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
3462 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
3464 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
3465 terms of the libart functions. Removed the old code.
3467 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
3468 symbols. Saving will not be implemented in GdkPixbuf.
3470 * src/io-gif.c: Removed the saving stub.
3471 (image_load): Fixed memory management to fail gracefully if we run
3472 out of memory while loading the image. Close the gif file when we
3473 are done. This still needs more error handling for the DGif
3476 * src/io-jpeg.c (image_load): Some robustness fixes.
3478 * src/io-png.c: Removed the saving stuff.
3479 (image_load): Some memory management fixes.
3481 * src/io-tiff.c (image_load): Ditto.

3489 * autogen.sh: use subautogen.sh
3491 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3493 * src/*: Reindented to use the GNOME Indentation. Renamed
3494 GdkPixBuf to GdkPixbuf, for consistency with the function names
3495 (and it is also easier to type) :-)
3497 1999-10-18 Havoc Pennington <hp@pobox.com>
3499 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
3501 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
3503 1999-10-18 Havoc Pennington <hp@pobox.com>
3505 * Makefile.am (SUBDIRS): Remove "macros"
3507 * configure.in: Don't use GNOME_INIT, handle case where we are
3508 inside gnome-libs. AM_PATH_GTK for the GIF test
3510 * src/Makefile.am: Change flags to work without libgnomeui,
3511 comment out testpixbuf for now
3513 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3515 * configure.in: Use $GTK_LIBS as the extra libs when checking for
3516 libgif/libungif, as they need the X libraries. Fixes bug #2472.
3518 1999-10-10 Cody Russell <bratsche@dfw.net>
3519 * src/gdk-pixbuf-drawable.c: core function now determines whether
3520 the requested geometry is on screen or not, and if some is not
3521 then the request is clamped to geometry that is on the screen.
3523 Changed 'pixbuf' to 'art_pixbuf' in core function.
3525 1999-10-08 Michael Fulbright <drmike@redhat.com>
3527 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.
3529 * src/testpifbuf: Changed test program to display cdrom from rgb data
3530 if no filename given to test program.
3532 1999-10-07 Cody Russell <bratsche@dfw.net>
3533 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
3534 them, but I wrote them).
3536 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
3539 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
3540 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.
3542 * src/gdk-pixbuf-drawable.c: Added #include "gdk-pixbuf-drawable.h"
3545 * src/gdk-pixbuf-drawable.[ch]: Changed functions to return
3546 GdkPixBuf* instead of ArtPixBuf*.

3560 * src/io-tiff.c (image_load): ditto + fix leak
3562 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
3563 crashes this module ( add warning :-)
3565 * src/io-bmp.c (image_load): ditto.
3567 * src/io-gif.c (image_load): ditto.
3569 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
3571 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
3572 it doesn't crash scaling with alpha.
3574 1999-09-17 Federico Mena Quintero <federico@redhat.com>
3576 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
3578 * src/io-gif.c (image_load): Likewise.
3580 * src/io-jpeg.c (image_load): Likewise.
3582 * src/io-png.c (image_load): Likewise.

3597 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
3598 to unallocated memory (row_ptr), and fixed its type as well. Take
3599 into account the ArtPixbuf's rowstride when assigning the row
3602 * src/gdk-pixbuf.c: Fixup includes.
3604 * src/gdk-pixbuf-io.c: Likewise.
3606 Sat Jul 31 19:19:47 CEST 1999

3609 * src/io-png.c: Fixed two obvious C syntax bugs
3611 1999-07-29 Mark Crichton <crichton@gimp.org>
3613 * src/io-png.c (image_save): Added PNG saving function
3615 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
3616 image_save(GdkPixBuf *p, FILE *f, ...)
3619 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
3621 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3622 require extra libraries if we actually have those libraries.
3624 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3626 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
3627 * gdk_pixbufConf.sh.in: Added for gnome-config
3629 * configure.in: Modified to generate gdk_pixbufConf.sh
3631 1999-07-20 Mark Crichton <crichton@gimp.org>
3633 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3634 calculation needs to be done.
3636 1999-07-18 Larry Ewing <lewing@gimp.org>
3641 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3642 error cases but one or two in the common case. There are probably
3643 a few small ones left.
3645 1999-07-18 Mark Crichton <crichton@gimp.org>
3647 * configure.in: removed version.h.
3649 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3652 1999-07-17 Mark Crichton <crichton@gimp.org>
3654 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
3655 (gdk_pixbuf_rotate): Added pixbuf rotation code.
3656 (gdk_pixbuf_scale): Changed // comments to /* */
3658 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
3661 1999-07-16 Larry Ewing <lewing@gimp.org>
3663 * src/testpixbuf.c (expose_func): reverted the expose everything
3664 changes, I'm not sure why these went in.
3665 (config_func): bring this up to date with the new pixbuf_scale
3668 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3669 loading code so that poeple can diagnose problems better.
3671 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3672 no longer allocates a new pixbuf, which make things nicer for the
3673 rest of the code. Unfortunately there is still a problem with
3674 scaling rgba images.
3676 1999-07-16 Mark Crichton <crichton@gimp.org>
3678 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3679 calls gdk_pixbuf_scale. However, something is not working.
3680 N.B.: current pixmap is now stored in user_data with a key of
3683 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
