7 2003-07-18 Matthias Clasen <maclas@gmx.de>
9 * pixops/pixops.c (correct_total): Split correction into multiple pieces if no single weight is large

56 type. (#105324, Dom Lachowicz)
58 * io-gif.c (gif_get_extension): Reset block_count to 0 for all application extensions, otherwise the data blocks
59 of unknown extensions are not propertly skipped.
61 Second half of the fix for #106962, handle frames extending beyond the logical screen:

66 when operating on the composite pixbuf and when calling update_func.
67 (gif_init): Set the animation size to the logical screen size.

527 * pixops/pixops.c: Fix problem where when no alpha was
528 involved, we scaled rather than composited, but then
529 went ahead and composited anyways. (#76958, Patch
530 from Matthias Clasen). Needs to be merged to GNOME
533 2002-06-13 Matthias Clasen <maclas@gmx.de>
535 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
536 incrementally display incrementally loaded progressive jpegs.
538 2002-06-07 Federico Mena Quintero <federico@ximian.com>
541 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
542 starting at a specific memory location. We do this instead of
543 GINT32_FROM_LE() as the latter is simply dereferences a cast,
544 which doesn't work on platforms with alignment requirements.
547 2002-06-01 Matthias Clasen <maclas@gmx.de>
549 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
550 with a C comment - those seem to be not uncommon, e.g. the Gimp
551 produces them. (#82706)
553 * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
555 (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.
557 2002-05-22 Tor Lillqvist <tml@iki.fi>
559 * gdk-pixbuf-io.c (get_libdir): Use GTK_BINARY_VERSION (and not
560 GTK_VERSION) in the path to the loaders on Win32, too.
562 * Makefile.am: Pass GTK_BINARY_VERSION.
564 2002-05-22 Federico Mena Quintero <federico@ximian.com>
566 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
567 account!!! Fixes #82515.
569 [This bug is not present in the GNOME 1.4 branch as its XPM loader
570 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
571 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
573 [IMPORTANT: The comment above is to make my life easier when
574 merging stuff across branches. If you make changes to gdk-pixbuf
575 in either branch, please include a comment in the ChangeLog that
576 indicates whether this should be merged into the other branch.
579 2002-05-18 Matthias Clasen <maclas@gmx.de>

594 2002-05-07 Michael Natterer <mitch@gimp.org>
596 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
597 conditionally like the dynamic ones so --without-lib<foo> is
598 honored when building with --disable-modules. (#66867)
600 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
602 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to

606 2002-04-24 Matthias Clasen <maclas@gmx.de>
608 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
609 restriction from the description of png tEXt parameters.
611 * io-png.c (png_text_to_pixbuf_option):
612 (gdk_pixbuf__png_image_save): If libpng supports it,
613 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
615 2002-04-11 Matthias Clasen <maclas@gmx.de>
617 More fixes for #77807:
619 * io-tga.c (get_contiguous_pixbuf): Helper function to create
620 a pixbuf with a contiguous pixel array while being careful about
623 * io-tga.c (fill_in_context, get_image_pseudocolor,
624 get_image_truecolor, get_image_grayscale): Use
625 get_contiguous_pixbuf instead of manually allocating image
628 * io-xpm.c (pixbuf_create_from_xpm):
629 * io-pnm.c (gdk_pixbuf__pnm_image_load):
630 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
631 instead of manually allocating image storage.
633 2002-04-09 Matthias Clasen <maclas@gmx.de>
635 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
636 priv->image_module->module_name instead of image_type which may
639 2002-04-06 Matthias Clasen <maclas@gmx.de>
641 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
642 gdk_pixbuf_new instead of manually allocating image storage. This
643 gives us a good rowstride and overflow checks. (#77807)
645 2002-04-05 Matthias Clasen <maclas@gmx.de>
647 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
648 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable

656 2002-03-29 Matthias Clasen <maclas@gmx.de>
658 * io-png.c (png_simple_error_callback): libpng error handlers must
659 not return to their callers, thus longjmp out. This prevents
660 annoying stderr output from the default error handler.
662 2002-03-27 Matthias Clasen <maclas@gmx.de>
664 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
666 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
667 end_info. Also call png_read_end to check proper ending of the png
668 file and catch text chunks after the image data.
670 2002-03-27 Matthias Clasen <maclas@gmx.de>
672 * io-png.c (gdk_pixbuf__png_image_load,
673 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
674 instead of system malloc.
676 2002-03-26 Matthias Clasen <maclas@gmx.de>
678 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
680 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
681 context->buf on error.
683 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
684 stop_load even for short images to prevent memleaks.
686 2002-03-25 Matthias Clasen <maclas@gmx.de>
688 * io-png.c (setup_png_transformations): Changed signature to
689 return success and set a GError parameter, adjusted all callers.
690 Also work around a possible FPE in libpng and always check that
691 the new info is sane.
693 2002-03-23 Matthias Clasen <maclas@gmx.de>
695 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
696 context->updated_func is NULL during a nonincremental load.
697 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
699 2002-03-18 Matthias Clasen <maclas@gmx.de>
701 * io-tga.c: Fix assumptions on rowstride by manually allocating a
702 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
703 Support grayscale + alpha (which can be written, but not read (!)
706 2002-03-15 Matthias Clasen <maclas@gmx.de>
708 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
710 2002-03-13 Matthias Clasen <maclas@gmx.de>
712 * test-images.h: Add valid_ras_test and invalid_bmp_1.
714 * test-loaders.c (main): Add random tests for ras and pnm and an
715 invalid bmp which was a crasher until my 2002-03-12 commit.

720 * io-ras.c: Handle some errors.
722 2002-03-12 Sven Neumann <sven@gimp.org>
724 * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
725 calling memcpy(). Simpler and potentially faster. (#70332)
727 2002-03-12 Matthias Clasen <maclas@gmx.de>
729 * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
730 which could actually be reached by a proper error status return.
732 2002-03-05 Matthias Clasen <maclas@gmx.de>
734 * test-loaders.c, test-images.h: More random tests.
736 * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.

746 * gdk-pixbuf-io.c (_gdk_pixbuf_load_module): If we
747 can't load the module using the g_module_build_path()
748 filename, try loading it as a .la file.

751 rather than .libs, so we find the right .la files.
753 * test-loaders.c: Back out some accidental commits.
755 Sat Mar 2 21:28:03 2002 Owen Taylor <otaylor@redhat.com>

1076 * gdk-pixbuf.h, gdk-pixdata.c: Rename gdk_pixbuf_new_from_stream()
1077 back to gdk_pixbuf_new_from_inline(). Rework docs to try
1078 and be helpful for the common case. (#58308)
1080 2001-10-05 Sven Neumann <sven@gimp.org>
1082 * gdk-pixbuf/gdk-pixbuf-io.c
1083 * gdk-pixbuf/gdk-pixbuf-private.h
1084 * gdk-pixbuf/gdk-pixbuf.c
1085 * gdk-pixbuf/gdk-pixbuf.h
1086 * gdk-pixbuf/io-jpeg.c
1087 * gdk-pixbuf/io-png.c: changed GDK_PIXBUF_ERROR_BAD_OPTION_VALUE to
1088 GDK_PIXBUF_ERROR_BAD_OPTION to we can use it for bad keys too. Added
1089 new public API gdk_pixbuf_get_option() to retrieve key/value pairs
1090 set by an image loader. Added support for saving and reading PNG tEXt
1091 chunks in PNG images.
1093 Tue Oct 2 11:29:50 2001 Owen Taylor <otaylor@redhat.com>
1095 * gdk-pixdata.c (gdk_pixdata_to_csource): Fix indentation
1096 use a macro to make code a bit more readable.
1098 2001-10-02 Sven Neumann <sven@gimp.org>
1100 * gdk-pixdata.c: g_string_printfa => g_string_append_printf.
1102 Wed Sep 26 18:08:19 2001 Owen Taylor <otaylor@redhat.com>
1104 * Makefile.am (s-enum-types-h): Fix a typo in the include
1105 guards. (#61254, Skip Montaro)
1107 2001-09-21 Matthias Clasen <matthiasc@poet.de>
1109 * io-xpm.c (xpm_extract_color): Rewritten to handle
1110 xpm colormap entries more thoroughly. (#59939)
1112 2001-09-21 Hans Breuer <hans@breuer.org>
1114 * gdk-pixbuf.def : updated externals
1116 * makefile.msc : generate gdk-pixbuf-enum-types.[hc]
1118 Thu Sep 20 17:22:48 2001 Owen Taylor <otaylor@redhat.com>
1120 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
1121 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't
1122 work here since we are using the raw file descriptor. So, we call lseek()
1123 on the fileno(f) before using it. (#60840).
1125 2001-09-20 James Henstridge <james@daa.com.au>
1127 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
1128 so that flags types are registered as flags rather than enums (not
1129 that there are any flags here at the moment).
1131 Wed Sep 19 00:28:24 2001 Owen Taylor <otaylor@redhat.com>
1133 * Makefile.am (gdk_pixbuf_headers): Don't include
1134 gkd-pixbuf-features.h here since is in builddir
1135 and confuses autogen rules.
1137 * Makefile.am: Don't += variables before they have values,
1138 automake-1.5 doesn't like it.
1140 * Makefile.am: Fix srcdir != builddir for gdk-pixbuf-enum-types.c.
1142 * Makefile.am: The whitespace strikes back.
1144 2001-09-17 Matt Wilson <msw@redhat.com>
1146 * Makefile.am (libpixbufloader_xbm_la_LDFLAGS): removed duplicate
1147 LDFLAGS definition, use the -avoid-version one.
1148 (libpixbufloader_tga_la_LDFLAGS): likewise
1150 Mon Sep 17 11:49:02 2001 Owen Taylor <otaylor@redhat.com>
1152 * pixops/*: Mirror GdkInterpType to PixopsInterpType
1153 to avoid including gdk-pixbuf headers.
1155 2001-09-16 James Henstridge <james@daa.com.au>
1157 * .cvsignore: add generated files to ignore list.
1159 * gdk-pixbuf.h: include gdk-pixbuf-enum-types.h
1161 * Makefile.am: add rules to build gdk-pixbuf-enum-types.[ch]
1163 Fri Sep 14 23:22:12 2001 Matthias Clasen <matthiasc@poet.de>
1165 * io-pnm.c (pnm_read_header): Use GDK_PIXBUF_ERROR_CORRUPT_IMAGE,
1166 not GDK_PIXBUF_ERROR_HEADER_CORRUPT. (#58308)
1168 Fri Sep 14 22:53:45 2001 Matthias Clasen <matthiasc@poet.de>
1170 * io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load): Handle
1171 out-of-memory situation better.
1173 * io-pnm.c: Robustness fixes for pnm loader
1175 * io-gif.c: Make gif loader survive TEST_RANDOMLY_MODIFY
1177 * io-xpm.c (parse_color): detect very long color strings
1179 All of the above from Matthias Clasen <matthiasc@poet.de>,
1180 the remaining from Soeren Sandmann <sandmann@daimi.au.dk>.
1182 * test-images.h: add tests:
1183 - four valid ppm's, eight invalid (matthiasc@poet.de)
1184 - one invalid xpm (matthiasc@poet.de)
1185 - one valid tga, one invalid (sandmann@daimi.au.dk)
1186 - one invalid tiff (sandmann@daimi.au.dk
1188 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
1190 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
1191 fail - detect it when it happens
1193 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
1196 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
1199 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
1201 * Makefile.am: don't used BUILT_SOURCES to build marshal
1202 files, as in conjunction with stamp files, this can
1203 lead to endless rebuilding loops.
1205 Tue Sep 4 00:22:07 2001 Owen Taylor <otaylor@redhat.com>
1207 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1
1209 Tue Sep 4 03:09:52 2001 Tim Janik <timj@gtk.org>
1211 * gdk-pixbuf-csource.1: new file, manual page for
1212 the publically installed gdk-pixbuf-csource utility.
1214 Thu Aug 30 08:30:03 2001 Matthias Clasen <matthiasc@poet.de>
1216 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Propagate
1217 errors from gdk_pixbuf_loader_load_module.
1219 Thu Aug 30 08:27:37 2001 Matthias Clasen <matthiasc@poet.de>
1221 * io-png.c (png_row_callback): Check that row_num is valid.
1223 Tue Aug 28 21:05:26 2001 Matthias Clasen <matthiasc@poet.de>
1225 * io-bmp.c (OneLine): Emit area_updated signal with proper
1226 area information. (#52002)
1228 Tue Aug 28 20:03:43 2001 Matthias Clasen <matthiasc@poet.de>
1230 * test-loaders.c (test_loader): Catch errors at close time.
1231 * test-loaders.c (main): Remove C++ comments.
1233 2001-08-21 Matthias Clasen <matthiasc@poet.de>
1235 * Makefile.am, gdk-pixbuf-io.c, pixbufloader_tga.def,
1236 io-tga.c: Add tga loader, patch by Nicola Girardi. (#56067)
1238 2001-08-20 Matthias Clasen <matthiasc@poet.de>
1240 * test-images.h, test-loaders.c: Add ico and wbmp tests.
1241 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): Fail with a suitable
1242 error if buffer allocation fails.
1243 * io-ico.c: Make .ICO loader more robust.
1244 All of these are due to sandmann@daimi.au.dk (#50187)
1246 2001-08-19 Sven Neumann <sven@gimp.org>
1248 * pixops/pixops.c: applied some simple but effective optimizations
1249 to pixops_composite_nearest() and pixops_composite_color_nearest().
1251 2001-08-07 Sven Neumann <sven@gimp.org>
1253 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
1254 function, so that's what I did.
1256 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
1258 * gdk-pixdata.c: Fix a typo.
1260 2001-07-30 Hans Breuer <hans@breuer.org>
1262 * pixops/makefile.msc : new file
1263 * makefile.msc : use it to complete the build
1265 2001-07-20 Hans Breuer <hans@breuer.org>
1267 * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
1268 pointer increment out of the macro, because at least one
1269 compiler (msvc 5.0) gets confused otherwise (applies the
1272 * gdk_pixbuf.def : updated exports
1274 * makefile.msc : reflect gdk-pixbuf-csource changes
1276 2001-07-17 Darin Adler <darin@bentspoon.com>
1278 * gdk-pixbuf-csource.c: Add missing <stdlib.h> include.
1279 * io-png.c: (setup_png_transformations): Add ifdef so we compile
1280 without warnings with G_DISABLE_CHECKS on.
1281 * io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
1283 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
1284 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
1285 unused locals and add an initial value to quiet the compiler's
1286 unintialized variable warning.
1287 * pixops/pixops.c: Put an ifdef around some dead code.
1289 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
1291 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
1292 over to the new include flags AC_SUBST(). (Problem
1293 pointed out by Mikael Hermansson.)
1295 2001-06-29 Havoc Pennington <hp@redhat.com>
1297 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): fix for
1300 Thu Jun 28 21:54:19 2001 Owen Taylor <otaylor@redhat.com>
1302 * make-inline-pixbuf.c test-gdk-pixbuf.c test-loaders.c
1303 gdk-pixbuf-csource.c: Fix args to g_type_init ().
1305 2001-06-28 Havoc Pennington <hp@pobox.com>
1307 * gdk-pixdata.c: <string.h>
1309 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
1310 also leaking memory here from g_strdup_printf?)
1312 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
1314 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
1316 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
1317 instead from gdk_pixbuf_new_from_inline().
1319 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
1320 installed API for applications that need to serialize/deserialize
1321 on their own (gimp, BEAST).
1323 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
1324 program that can dump images in CSource format and Pixbuf
1325 stream format. supports RLE encoding, MACRO formatting etc...
1328 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
1330 * Makefile.am: Actually update timestamps, so rules don't
1333 2001-06-11 Havoc Pennington <hp@redhat.com>
1335 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
1336 already includes top_builddir
1338 2001-06-08 Havoc Pennington <hp@redhat.com>
1340 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
1341 bogus g_return_if_fail
1343 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
1344 likely timeout resolution, set it to an arbitrarily-chosen short
1346 Fixes bug #55953 from warmenhoven@yahoo.com
1348 2001-06-07 Havoc Pennington <hp@redhat.com>
1350 * Makefile.am: use Owen's new way of doing stampfiles/generated
1353 2001-06-07 Havoc Pennington <hp@redhat.com>
1355 * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path
1357 2001-06-05 Havoc Pennington <hp@redhat.com>
1359 * test-loaders.c (main): use putenv not setenv, reported by
1362 2001-05-08 Havoc Pennington <hp@redhat.com>
1364 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1365 and fix behavior to still subst color if the original image
1368 2001-06-04 Havoc Pennington <hp@redhat.com>
1370 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1373 2001-06-01 Havoc Pennington <hp@redhat.com>
1375 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1376 Makes things a bit more robust, and adds test-loaders.c
1377 which is good for finding further robustness bugs to fix.
1379 * io-tiff.c: Try to work around libtiff suckiness a bit;
1380 put a giant thread lock on the whole loader,
1381 paranoically check both whether error handlers were called and
1382 also whether functions return false. Handle case where width or
1383 height is 0. Various cleanups.
1385 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1387 (png_error_callback): apparently libpng expects you to longjmp out
1390 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1391 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1393 (gif_get_lzw): check for out-of-memory
1394 (gif_prepare_lzw): catch/report an error
1395 (new_context): use try_malloc, since GifContext is nearly 70K
1396 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1397 so we don't crash later.
1399 * Makefile.am: Add test-loaders
1401 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1404 2001-05-29 Darin Adler <darin@eazel.com>
1406 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1408 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1410 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1411 fix up bmp decoder to:
1412 - adds 16 bpp bmp support (bug #53884)
1413 - adds OS/2 1.x format bmp support (bug #54964)
1414 - adds 4 bpp RLE compressed bmp support
1415 - adds 1 bpp colormap support
1416 - fixes negative height (top down) bmp support
1418 2001-05-25 Hans Breuer <hans@breuer.org>
1420 * gdk_pixbuf.def : reflect Havoc's recent api change
1422 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1424 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1425 excess $(GLIB_LIBS).
1427 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1429 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1431 2001-05-04 Havoc Pennington <hp@redhat.com>
1433 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1434 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1437 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1438 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1439 confusion of using "src" instead of "p".
1440 (pixops_composite_color_nearest): Use a more accurate (and
1441 correct, to begin with) compositing method. This cures checks
1442 showing through on images with no alpha.
1444 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1447 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1449 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1450 area_updated signal to use signed ints. Removed animation-related
1453 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1456 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1457 all the pesky details. Remove old frame-based API. Make
1458 GdkPixbufAnimation an abstract base class, derived by the loaders.
1460 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1462 * Makefile.am (LDADDS): Add $(MATH_LIB).
1464 2001-04-18 Havoc Pennington <hp@redhat.com>
1466 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1469 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1471 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1472 so we don't try to get <gtk/gtkobject.h> from standard search
1475 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1476 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1477 take gdk-pixbuf-marshal.h out of _la sources.
1479 2001-03-19 Tor Lillqvist <tml@iki.fi>
1481 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1483 * gdk_pixbuf.def: Update.
1485 * pixbufloader_*.def: Just export the fill_vtable functions now.
1487 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1489 * make-inline-pixbuf.c (main): Added logic to remove output when
1492 2001-03-14 Havoc Pennington <hp@redhat.com>
1494 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1495 from gdk-pixbuf-marshal.h, fixes parallel makes.
1497 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1499 * test-gdk-pixbuf.c: fixed includes.
1501 2001-02-18 Havoc Pennington <hp@pobox.com>
1503 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1504 (gdk_pixbuf_get_named_module): prepend underscore
1505 (gdk_pixbuf_get_module): prepend underscore
1507 2001-02-19 Havoc Pennington <hp@redhat.com>
1509 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1511 2001-02-17 Havoc Pennington <hp@pobox.com>
1513 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1515 2001-02-07 Alexander Larsson <alexl@redhat.com>
1517 * io-xpm.c (free_buffer):
1518 Use g_free, since the buffer is allocated with g_try_alloc().
1520 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1522 * gdk-pixbuf-data.c: Fixes a minor typo.
1524 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1526 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1527 we finally need the gobject->gruntime rename.
1529 * *.c: scratched calls to g_type_init(), there's simply no point in
1530 doing that, use gtk_init().
1532 2001-02-01 Havoc Pennington <hp@pobox.com>
1534 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1535 in struct to "priv" for C++
1537 2001-01-31 Havoc Pennington <hp@pobox.com>
1539 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1541 2001-01-26 Havoc Pennington <hp@redhat.com>
1543 * gdk-pixbuf-io.c (mname): fix included modules case.
1545 2001-01-22 Havoc Pennington <hp@redhat.com>
1547 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1548 from gdk_pixbuf_load_module
1550 2001-01-22 Havoc Pennington <hp@redhat.com>
1552 * Makefile.am: Add built marshaller files to support
1553 GdkPixbufLoader signals
1555 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1556 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1557 module location, rather than acting as a fallback, because we are
1558 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1560 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1562 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1563 from gtk, and add error to close(), because stop_load may do
1564 parsing of the image.
1566 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1568 * io-*.c: make individual operations static, and add fill_vtable
1569 functions which are exported. Fix the collection of type warnings
1570 that surfaced, including a number of functions that didn't
1571 properly take a GError and some that weren't
1572 const-correct. Involved adding error handling for a few loaders.
1574 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1576 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1577 a function that fills in the GdkPixbufModule vtable, instead of
1578 looking up all the image functions individually; this means we
1579 can get type safety within modules for the loader functions.
1580 Also it means you don't have to keep the statically compiled and
1581 GModule versions in sync.
1583 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1585 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1587 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1589 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1592 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1594 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1597 2001-01-20 John Harper <jsh@eazel.com>
1599 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1600 collision between Xlib's RdBitF.c and io-tiff.c
1602 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1605 [ merged from stable gdk-pixbuf module. Untested, but it
1606 compiles, and works fine in the stable module ]
1608 2001-01-18 Tor Lillqvist <tml@iki.fi>
1610 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1611 g_win32_get_package_installation_subdirectory() function. No need
1612 to include windows.h.
1613 (gtk_win32_get_installation_directory): Remove this then.
1615 2001-01-01 Havoc Pennington <hp@redhat.com>
1617 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
1618 @LIBTOOL_EXPORT_OPTIONS@

1626 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1627 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1628 (gdk_pixbuf_frame_copy): new function
1629 (gdk_pixbuf_frame_free): new function
1630 (gdk_pixbuf_frame_get_type): new function

1640 say "save" since it's used for loading
1642 2000-11-11 Hans Breuer <Hans@Breuer.Org>
1644 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1645 contained image handlers (!USE_G_MODULE). Files to save should
1646 be opened in binary mode, fopen(s, "wb").
1648 * io-xpm.c : added HAVE_UNISTD_H condition
1650 2000-11-11 Tor Lillqvist <tml@iki.fi>
1652 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1654 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1655 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1656 mktemp() and open()).
1658 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1660 2000-11-01 Havoc Pennington <hp@pobox.com>
1662 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1663 a pixbuf pointing to a subregion of another pixbuf.
1665 2000-10-16 Tor Lillqvist <tml@iki.fi>
1667 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1669 2000-10-16 Havoc Pennington <hp@redhat.com>
1671 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1672 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1673 add error reporting here also
1675 * make-inline-pixbuf.c (main): use GError
1677 * io-xpm.c: include unistd.h
1679 * gdk-pixbuf-util.c: include string.h
1681 * io-*.c: add error reporting
1683 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
1686 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
1688 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1691 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1692 a G_FILE_ERROR if we fail to write or close the file.
1694 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1695 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1696 the GError naming rules. Add GError** to load functions.
1698 2000-10-06 Havoc Pennington <hp@redhat.com>
1700 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1702 2000-10-06 Havoc Pennington <hp@redhat.com>

1730 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
1732 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
1733 last nights code was still "broken". Should now properly handle
1734 all error conditions gracefully.
1736 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
1738 * gdk-pixbuf/io-pnm.c: Rewrote.
1740 2000-09-09 Federico Mena Quintero <federico@helixcode.com>
1742 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
1743 the correct dest offset.
1745 2000-08-25 Federico Mena Quintero <federico@helixcode.com>
1747 * gdk-pixbuf/io-xpm.c: #include <unistd.h>
1749 2000-08-05 Larry Ewing <lewing@helixcode.com>
1751 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
1753 * gdk-pixbuf/io-xpm.c: same as above.
1755 2000-07-26 Michael Meeks <michael@helixcode.com>
1757 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
1760 2000-07-21 Larry Ewing <lewing@helixcode.com>
1762 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
1763 xpm at least supports the progressive interface like the one in
1764 io-tiff.c. This should be reimplemented as an actual progressive
1767 2000-07-19 Jonathan Blandford <jrb@redhat.com>
1769 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
1770 make it look better.
1771 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
1772 meeks to handle errors better.
1774 2000-10-07 Tor Lillqvist <tml@iki.fi>
1777 * pixbufloader_jpeg.def
1778 * pixbufloader_png.def: Add new entry points.

1782 2000-10-06 Havoc Pennington <hp@redhat.com>
1784 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
1785 consistent with gdk_pixbuf_loader_new_with_type().
1786 Return runtime error if a module is missing.
1788 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
1790 2000-10-05 Havoc Pennington <hp@redhat.com>
1792 Pixbuf saving, patch from David Welton.
1794 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
1795 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
1797 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf
1799 * io-png.c (gdk_pixbuf__png_image_save): PNG save routine.
1801 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): JPEG save routine.
1803 * gdk-pixbuf-io.c (gdk_pixbuf_save):
1804 (gdk_pixbuf_savev): Implement pixbuf saving routines
1806 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
1809 * gdk-pixbuf.h: Add public save routines; add pixbuf error
1812 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
1814 2000-10-05 Dan Winship <danw@helixcode.com>
1816 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
1817 all three of these files are the JPEG image loader. (From
1820 2000-10-03 Tor Lillqvist <tml@iki.fi>
1822 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
1823 gdk-pixbuf's version number in the rule for makefile.mingw itself.
1825 * gdk_pixbuf.def: Add new entry points.
1827 2000-09-26 Havoc Pennington <hp@redhat.com>
1829 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
1830 function here, instead of putting it in a private GTK+ file.
1832 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
1833 enum here for the known formats of inlined pixbufs.
1834 Also, #define our file magic here.
1836 2000-06-23 Havoc Pennington <hp@redhat.com>
1838 * make-inline-pixbuf.c: Small program that creates C variable
1839 declarations of inline pixbuf data. This can be read
1840 by gdk_pixbuf_new_from_inline.
1842 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
1843 inline pixbuf data and create a pixbuf from it.
1845 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1847 2000-09-07 Tor Lillqvist <tml@iki.fi>
1849 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1852 2000-08-12 Tor Lillqvist <tml@iki.fi>
1854 * gdk_pixbuf.def: Add missing entry point.
1856 2000-08-10 Havoc Pennington <hp@redhat.com>
1858 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1859 (s/pixbuf_/pixbufloader_)
1861 2000-08-02 Tor Lillqvist <tml@iki.fi>
1867 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1869 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1870 one. Fix names of DLLs to have '-' instead of '_'.
1872 2000-07-31 Elliot Lee <sopwith@redhat.com>
1873 * io-wbmp.c: Some bug fixes - now tested to work.
1875 2000-07-27 Elliot Lee <sopwith@redhat.com>
1877 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1878 gdk_pixbuf_get_named_module() function to facilitate above change
1879 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1880 Implement loader for WBMP format.
1881 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1883 2000-07-23 Tor Lillqvist <tml@iki.fi>
1888 * pixops/makefile.mingw.in
1889 * pixbuf_*.def: New files.
1892 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1894 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1895 New function, to get the GTK+ installation directory from
1896 the Windows Registry, where the installation program
1897 for whatever software includes GTK+ has stored it.
1899 Used to avoid having hardcoding the directory where to look for
1900 loaders. This function is needed by gtk, too, so it should
1901 really be just in one place. Maybe a small static library
1902 one level up from here?
1904 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1905 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1906 Open file in binary mode. This *is* standard C. (No-op on Unix,
1909 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1911 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1912 mktemp() and open().
1913 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1915 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1916 pseudo-op. Conditionalise on __MINGW32__, but probably
1917 should conditionalise on Gas version instead? Or could we
1918 do without .type on all systems?
1920 * pixops/timescale.c: Use g_get_current_time()
1921 instead of gettimeofday().
1923 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1925 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1927 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1929 * gdk-pixbuf.c: Add <string.h> include.
1931 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1933 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1934 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1935 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1936 use g_object_new() instead of g_type_create_instance() which
1937 is a private function for fundamental type implementations.
1939 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1941 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1942 soname scheme for gdk-pixbuf.
1944 2000-06-21 Havoc Pennington <hp@pobox.com>
1946 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1947 (i.e. derivation is not allowed, and there are no virtual methods
1949 (gdk_pixbuf_preinit): Call g_type_init() here.
1950 (gdk_pixbuf_init): Add a user-friendly init function, for users
1951 of standalone gdk-pixbuf
1953 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1954 way GdkPixbufAnimation was done.
1956 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1957 gdk_pixbuf_finalize() from API, since these are broken and don't
1958 make sense with new GObject stuff.
1960 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1962 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1963 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1966 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1968 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1969 so I needed something to warm my thighs. Running plain infinite
1970 loops on your laptop to make it hot is not very much fun. A demo
1971 of the gdk-pixbuf scaling functions is way better, and looks
1974 * configure.in (AC_OUTPUT): Added the demo Makefile.
1976 * Makefile.am (SUBDIRS): Added the demo directory.
1978 2000-06-09 Larry Ewing <lewing@helixcode.com>
1980 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1981 setjmp for the png error handler. It seems setting the error
1982 handling functions does not avoid the jump, and so not calling
1983 setjmp was causing the incremental loader to jump into lala land.
1984 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1985 not sure this one is actually required but the docs say it must be
1986 set for every call to a png_* function.
1987 Also changed the comment to reflect the fact that setting the
1988 error handlers does _not_ avoid the longjmp.
1990 2000-06-06 Larry Ewing <lewing@helixcode.com>
1992 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1993 take frame offest into account when trying to calculate the
1994 animation bbox. Also set the width to the width not the height.
1995 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1996 calculate bbox because now we finally have all the offset
1997 information for each frame.
1999 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
2001 * configure.in: add some gtk parameters to the
2002 GDK_PIXBUF_LIBĂƒĂ¯Â¿Â½Â²S and GDK_PIXBUG_INCLUDEDIR vars. One more
2003 fight in my crusade for strange prefix compile...
2005 2000-05-30 Not Zed <NotZed@HelixCode.com>
2007 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
2008 Initialise the error handler exit routine to our own. Note this
2009 means that every function that accesses the jpeg lib on this
2010 object MUST do a setjmp.
2011 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
2012 lib for handling fatal error.
2013 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
2014 your applications dont quit if there's a jpeg error!
2016 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
2018 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
2019 from Frank de Lange <frank@unternet.org>.
2021 2000-05-09 Darin Adler <darin@eazel.com>
2023 * gdk-pixbuf/test-gdk-pixbuf.c:
2024 Fixed includes to get rid of accidental GNOME dependency.
2026 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
2027 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
2029 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
2031 * configure.in: Bumped version number to 0.8.0.
2033 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
2034 file was not being distributed.
2036 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
2038 2000-05-09 Darin Adler <darin@eazel.com>
2040 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
2041 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
2042 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
2043 formats to 32-bit formats to re-use the high bits of the color values
2044 so that white maps to full white.
2046 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
2048 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
2049 detailed information about the structure and algorithms
2050 of pixops so people can fix it instead of breaking it.
2052 2000-05-04 Darin Adler <darin@eazel.com>
2054 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
2055 (composite_pixel), (composite_line):
2056 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
2057 Now that Owen explained the algorithm, I think I implemented it
2058 right for the cases where the destination pixbuf is not opaque.
2059 The test does seem to confirm it.
2061 2000-05-04 Darin Adler <darin@eazel.com>
2063 * gdk-pixbuf/.cvsignore:
2064 * gdk-pixbuf/Makefile.am:
2065 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
2066 (load_pixel), (simple_composite_test_one),
2067 (simple_composite_test_one_type), (simple_composite_test), (main):
2068 Added some tests of composite to highlight problems in the old
2069 implementation. These tests run without any user interaction.
2070 Just do "make check".
2072 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
2073 (composite_pixel), (composite_line): Fix composite to do a textbook
2074 "A over B" composite. This was clearly the intent, and it was easy
2075 to fix the code to do it. (Note to those that read my earlier tries
2076 at a patch; this version fixes typos that were present in all
2077 my patch attempts. I checked the final version by adding more tests.)
2079 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
2081 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
2082 offset y coordinate accordining to render_y0.
2084 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
2087 2000-04-22 James Henstridge <james@daa.com.au>
2089 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
2090 package to the devel package. The only file installed in bin is
2091 gdk-pixbuf-config, which belongs in -devel. This should allow having
2092 multiple versions of the main gdk-pixbuf package installed.
2094 2000-04-17 Karl Eichwalder <ke@suse.de>
2096 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
2097 Reported by Jens Finke.
2099 2000-04-14 Tomasz KĂƒĂ¯Â¿Â½Â³opczko <kloczek@pld.org.pl>
2101 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
2102 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
2104 2000-04-13 James Henstridge <james@daa.com.au>
2106 * configure.in: when performing the configure check to see if
2107 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
2108 rather than the other way round. Also, call AC_MSG_RESULT in the
2109 even that dynamic modules were not supported.
2111 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
2113 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
2114 hook to the last unref operation.
2116 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
2117 function to set the last unref handler for a pixbuf.
2118 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
2119 It calls the pixbuf's destroy notification function and frees the
2120 GdkPixbuf structure itself.
2121 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
2124 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
2125 for the last unref handler and its user data.
2127 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
2128 g_new0() to allocate the pixbuf.
2130 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
2131 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
2132 was not specifying the `frame' argument.
2134 * gdk-pixbuf/gdk-pixbuf-animation.c

2153 update the libtool version number for libgnomecanvaspixbuf as
2155 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
2156 as well, or the old ones won't work with the new stuff. Also,
2157 renamed the modules as follows.

2160 modules are called "libpixbufloader-<format>.so" instead of
2161 "libpixbuf-<format>.so". They needed renaming so that the new
2162 loaders won't overwrite the old ones; even with the versioning
2163 stuff, the new .so symlink to the .so.1.0.0 would overwrite the

2666 (gif_get_lzw): remove memory_leak
2668 * doc/tmpl/gdk-pixbuf-loader.sgml: much longer long description
2671 2000-01-05 Owen Taylor <otaylor@redhat.com>
2673 * gdk-pixbuf/pixops/pixops.c (pixops_process): Fix computation of end of run indices.

2676 (Pointed out by Tomas Ogren)
2678 2000-01-05 Mark Crichton <crichton@gimp.org>
2680 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_eat_header_write):

2732 code that will eventually migrate into libart.
2734 * configure.in acconfig.h: Add checks for MMX compiler support
2736 * gdk-pixbuf/gdk-pixbuf.h gdk-pixbuf/gdk-pixbuf-scale.c:
2737 Nice wrapper routines for the code in pixops that operate
2738 on pixbufs instead of raw data.
2740 * gdk-pixbuf/testpixbuf-scale: Test program for scaling
2743 2000-01-05 Jonathan Blandford <jrb@redhat.com>
2745 * doc/tmpl/animation.sgml: Documentation changes.
2747 2000-01-01 Federico Mena Quintero <federico@helixcode.com>
2749 * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
2750 counting to animations. A web browser may want to share a single
2751 copy of an animated GIF if it appears multiple times in a web
2754 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
2755 animation functions here.
2756 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
2757 animation if the loader does not support multiframe loading and
2758 the single-frame load returned NULL. Check that the filename is
2759 not NULL. Updated inline documentation.
2760 (gdk_pixbuf_animation_ref): New function.
2761 (gdk_pixbuf_animation_unref): New function.
2762 Removed gdk_pixbuf_animation_destroy() in favor of reference
2765 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
2766 Prettified. Made ref_count assertion more paranoid. Check that
2767 the filename is not NULL.
2768 (gdk_pixbuf_get_module): Use guchar * and guint for buffer and
2770 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
2773 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
2774 with a reference count of 1.
2776 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
2777 gdk-pixbuf-animation.c.
2779 * doc/tmpl/animation.sgml: Populated. It is still missing a
2780 description of the overlay modes.
2782 * doc/gdk-pixbuf-sections.txt: Added the animation section. Moved
2783 the canvas item section to the end, as it will be moved later to
2786 * doc/gdk-pixbuf.sgml: Added the animation section.
2788 * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
2790 1999-12-26 Peter Teichman <pat@gnu.org>
2792 * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add
2793 $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker.
2794 This closes bug #4676.
2796 1999-12-23 Havoc Pennington <hp@pobox.com>
2798 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
2799 set to NULL here (specifically context->animation) was not being
2800 set to NULL. use g_new0() to alloc the struct.
2802 1999-12-20 Jonathan Blandford <jrb@redhat.com>
2804 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2805 correctly. Progressive loading needs some work, but that all
2806 needs doing from the gdk-pixbuf-loader end, not here.
2808 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2810 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2811 moved the file here. It seems natural to put this function here,
2812 as that's where the gdk_pixbuf_new_from_file function is, but it's
2813 still a little convoluted. The source files might be played with
2816 1999-12-14 Jonathan Blandford <jrb@redhat.com>
2818 * gdk-pixbuf/gdk-pixbuf-loader.c
2819 (gdk_pixbuf_loader_get_animation): Gets the animation from the
2822 1999-12-16 Federico Mena Quintero <federico@redhat.com>
2824 * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
2825 before using the GdkPixbuf rendering functions. Thanks to Joe
2826 Shaw <joe@off.net> for pointing this out.
2828 1999-12-13 Federico Mena Quintero <federico@redhat.com>
2830 * gdk-pixbuf/gnome-canvas-pixbuf.c
2831 (gnome_canvas_pixbuf_class_init): Renamed arguments to
2832 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
2833 consistency with the new canvas.
2834 (PixbufPrivate): Do the same renaming in the structure fields, for
2837 * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.
2839 1999-12-12 Federico Mena Quintero <federico@redhat.com>
2841 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
2842 conditional to see whether to link $(GNOME_LIBS) or not.
2844 1999-12-10 Jonathan Blandford <jrb@redhat.com>
2846 * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API.
2848 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
2849 make a warning go away.
2851 * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations.
2853 * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for
2856 1999-12-09 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2858 * gdk-pixbuf/gdk-pixbuf.h: Enable gdk_pixbuf_get_from_drawable()
2861 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
2862 Filled in body of function.
2863 (rgbconvert): Added GdkColormap parameter, and to all conversion
2865 (convert_real_slow): New function - should convert ANY visual/data
2866 format properly, but it aint fast. Used as a fallback when an
2867 optimised routine wont match.
2868 (rgbconvert): Do very specific tests on the data format to verify
2869 properly if the optimised version will do, otherwise use the
2870 fallback function for all other data formats.
2872 * gdk-pixbuf/Makefile.am: Re-enabled building of
2873 textpixbuf-drawable.
2875 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
2876 gdk_pixbuf_get_from_drawable().
2878 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
2880 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
2881 bug on two occasions.
2882 * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu
2883 function to the generic glib one.
2885 1999-12-08 Federico Mena Quintero <federico@redhat.com>
2887 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2888 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2889 checks and API definition. The body needs filling in and it needs
2890 to do the Right Thing(tm) for pixmaps plus the given colormap and
2891 windows and their own colormaps.
2893 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2894 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
2896 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
2898 * doc/tmpl/from-drawables.sgml: Populated.
2900 * doc/gdk-pixbuf.sgml: Added the from-drawables section.
2902 * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml.
2904 * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs
2907 1999-12-07 Federico Mena Quintero <federico@redhat.com>

2910 reference counting for GdkPixbuf structures.
2912 1999-12-07 Martin Baulig <martin@home-of-linux.org>
2914 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
2915 include $(GNOME_LIBS) here.
2917 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2919 Added missing "include <string.h>" to:
2920 * gdk-pixbuf/io-ras.c
2921 * gdk-pixbuf/io-bmp.c
2922 * gdk-pixbuf/io-ico.c
2924 1999-12-06 Federico Mena Quintero <federico@redhat.com>
2926 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
2929 1999-12-05 Federico Mena Quintero <federico@redhat.com>
2931 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2932 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2933 want, send me a patch to do the conditional stuff properly.
2934 Otherwise, please read the GNOME Programming Guidelines,
2935 especially the "CVS policies" section.
2937 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
2939 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
2941 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2943 * gdk-pixbuf/io-ico.c: Bug in palet-size
2946 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
2948 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
2949 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
2951 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
2953 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
2956 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
2957 (Windows Cursor files). These are identical to .ICO files,
2958 except for the signature and 2 extra fields for the hotspot.
2960 1999-12-03 Federico Mena Quintero <federico@redhat.com>
2962 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):
2963 Removed unused variable `item'.
2965 1999-12-03 Jonathan Blandford <jrb@redhat.com>
2967 * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
2968 explain this function better.
2970 1999-12-02 Federico Mena Quintero <federico@redhat.com>
2972 Source files moved from src/ to gdk-pixbuf/, to be consistent with
2975 * doc/Makefile.am: Modified for the new source directory.
2977 * configure.in: Likewise.
2979 * Makefile.am: Likewise.
2981 * autogen.sh: Likewise.
2983 * gdk-pixbuf/Makefile.am: Likewise.
2985 1999-12-02 Federico Mena Quintero <federico@redhat.com>

3047 1999-11-29 Owen Taylor <otaylor@redhat.com>
3049 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
3050 Keep the mask around until after we draw ... since
3051 the GC changes aren't flushed to the X server until we
3052 draw, destroying it before that may result in BadPixmap
3055 1999-11-30 Havoc Pennington <hp@pobox.com>
3057 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
3059 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
3061 1999-11-29 Federico Mena Quintero <federico@redhat.com>
3063 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
3064 should be made conditional, not blindly commented out.
3066 1999-11-29 Jonathan Blandford <jrb@redhat.com>
3068 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
3069 handle .ico files. Cool.

3073 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
3076 1999-11-24 James Henstridge <james@daa.com.au>
3078 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
3079 top builddir rather than src. This still builds fine, and does not
3080 get gtk-doc into an infinite loop when trying to find all the source
3083 1999-11-23 Jonathan Blandford <jrb@redhat.com>
3085 * Removed #PRAGMA } from headers. Also, make compile if you don't
3086 have it installed, already.
3088 1999-11-22 Federico Mena Quintero <federico@redhat.com>
3090 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
3091 temporary buffer to the size of the interesction of the bounding
3092 box and the expose area, not the whole expose area. This speeds
3095 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
3096 not paint black on the mask, since we already cleared it in a
3097 single gdk_draw_rectangle() operation.
3099 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
3101 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
3103 1999-11-22 Havoc Pennington <hp@pobox.com>
3105 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
3106 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
3107 dependencies to LIBADD variables for loadable modules. Necessary
3108 for a Java dynamic loading thing to be able to figure it out.
3110 1999-11-22 Havoc Pennington <hp@pobox.com>
3112 * src/io-png.c (image_load_increment): Call the update_area
3113 callback depending on the number of rows loaded in this increment.
3115 * src/testpixbuf.c (main): slow down the progressive load demo
3117 1999-11-16 Havoc Pennington <hp@pobox.com>
3119 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
3121 1999-11-22 Jonathan Blandford <jrb@redhat.com>
3123 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
3124 for srcdir != buildir != . Beats me why; I can't figure it out.
3125 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
3127 1999-11-21 Jonathan Blandford <jrb@redhat.com>
3129 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
3130 <arjan@fenrus.demon.nl>
3132 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
3134 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
3135 Rework/reorder of the code. Each case has been separated into
3136 another function; its big but it should be quick.
3137 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
3138 opaque alpha information. Not all depths/formats have been
3139 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
3141 1999-11-17 Larry Ewing <lewing@gimp.org>
3143 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
3144 implement the bounds method correctly.
3145 (compute_viewport_affine): compute the affine need to fit the
3146 image within the viewport given by the args.
3147 (compute_render_affine): call compute_viewport_affine.
3149 1999-11-16 Havoc Pennington <hp@pobox.com>
3151 * src/gdk-pixbuf-drawable.h: Use includes from the current
3152 directory, not the system directory.
3154 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
3156 * src/testpixbuf-drawable.c: use includes from the current directory
3157 rather then from the system include directory as gdk-pixbuf
3158 includes are not yet installed when this is compiled.
3160 1999-11-13 Cody Russell <bratsche@dfw.net>
3161 * src/testpixbuf-drawable.c: Added a test program for drawable
3164 * src/Makefile.am: Build testpixbuf-drawable.
3166 1999-11-12 Cody Russell <bratsche@dfw.net>
3168 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.

3174 * doc/gdk-pixbuf.signals: Put in the real names of signal
3177 * src/gdk-pixbuf-loader.c: Improved documentation comments.
3179 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3181 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
3184 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
3185 correctly. Patch from Arjan to do so.
3187 1999-11-10 Michael Fulbright <drmike@redhat.com>
3189 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
3192 * src/testpixbuf.c: Added final queued draw when done loading image.
3194 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3196 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
3199 1999-11-10 Federico Mena Quintero <federico@redhat.com>
3201 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
3204 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3206 * src/io-png.c: Fixed some incompatible pointer initializations.
3208 * src/io-jpeg.c (image_load_increment): Remove unused variable.
3210 1999-11-09 Michael Fulbright <drmike@redhat.com>
3212 * src/testpixbuf.c: Fixed it to use timeout to read from file
3213 for progressive loading. Set TBF_KBPS=n, where n is the number of
3214 kilobytes/second to simulate in downloading. n has to be an integer.
3216 * src/io-jpeg.c: Slight cosmetic cleanup.
3218 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
3219 PBM loading has a similar problem and will address tomorrow.
3221 1999-11-09 Havoc Pennington <hp@pobox.com>
3223 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
3224 gdk-pixbuf-drawable stuff.
3226 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3228 * configure.in: Bumped version number to 0.4.
3230 1999-11-09 Michael Fulbright <drmike@redhat.com>
3232 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
3233 all types of PNM files now.
3235 * src/io-jpeg.c (image_load_increment): Figured out problem with
3236 loading Progressive JPEG's progressively (say that 10 times fast).
3237 Currently for Progressive JPEG's the entire image is loaded before
3238 it is displayed. libjpeg supports a fancier mechanism which I may
3241 With these changes all JPEG formats appear to load properly for me.
3243 1999-11-08 Jonathan Blandford <jrb@redhat.com>
3245 * src/io-ras.c (image_load_increment): Final patch from Arjan.
3246 Seems to do progressive loading.
3248 1999-11-08 Michael Fulbright <drmike@redhat.com>
3250 * src/io-pnm.c image_load (): Fixed so we do not create a separate
3251 pixel buffer when reading in image - we reuse the pixel data in
3252 the GdkPixbuf structure instead.
3254 1999-11-08 Michael Fulbright <drmike@redhat.com>
3256 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
3257 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
3258 I can't seem to find a utility to convert into this format.
3259 Next is to add progressive loading support for the PNM format.
3261 1999-11-07 Federico Mena Quintero <federico@redhat.com>
3263 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
3264 of the width, height, x, and y setting and pixels arguments.
3266 1999-11-05 Jonathan Blandford <jrb@redhat.com>
3268 * src/io-ras.c (image_load): third patch. Now it seems to load.
3270 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
3271 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
3273 * src/io-ras.c (image_load): new file from Arjan van de Ven
3274 <arjan@fenrus.demon.nl> to begin the ras loader.
3276 1999-11-05 Federico Mena Quintero <federico@redhat.com>
3278 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
3279 for internal use only.
3281 * doc/gdk-pixbuf.sgml: Likewise.
3283 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
3285 1999-11-05 Michael Fulbright <drmike@redhat.com>
3287 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
3288 files from a file. Next step is support for ASCII files, and
3289 then incremental loading.
3291 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3293 * Makefile.am: Added doc to SUBDIRS.
3295 1999-11-04 Michael Fulbright <drmike@redhat.com>
3297 * src/io-jpeg.c: Prettied up code slightly.
3298 * src/io-pnm.c: Start of pnm loader (from file and progressively).
3299 Doesn't do much yet (will finish tomorrow).
3300 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
3302 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3304 * doc/tmpl/rendering.sgml: Populated.
3306 * doc/Makefile.am: Added the template files.
3308 1999-11-04 Havoc Pennington <hp@pobox.com>
3310 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
3311 docs, explain what a dither offset is for.
3312 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3313 this function vs. gdk_pixbuf_render_to_drawable().
3315 1999-11-04 Havoc Pennington <hp@pobox.com>
3317 * configure.in: Use libart-config correctly; find gnome-config
3318 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3321 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3324 Patch untested in the inside-gnome-libs case, I need to commit
3325 then check out to the gnome-libs I'm using.
3327 1999-11-04 Michael Fulbright <drmike@redhat.com>
3329 * src/io-jpeg.c (image_begin_load): Add update_func callback.
3330 * src/io-jpeg.c (image_load_increment): Call updated callback when
3331 new graphic data decoded.
3333 1999-11-04 Jonathan Blandford <jrb@redhat.com>
3335 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_update): handle the
3337 * src/io-png.c (image_begin_load): add a update_func callback.
3338 * src/io-gif.c (image_begin_load): add a update_func callback.
3339 (gif_get_lzw): added the update_func ability

3343 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3345 * doc/tmpl/gdk-pixbuf.sgml: Populated.
3347 * doc/tmpl/refcounting.sgml: Populated.
3349 * doc/tmpl/file-loading.sgml: Populated.
3351 * src/gdk-pixbuf.c: Added documentation comments.
3353 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Added
3354 documentation comments.
3356 * doc/: Finished integrating the documentation framework.
3358 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3360 * configure.in: Removed libgif stuff now that we do not depend on it.
3361 Added the necessary cruft for gtk-doc.
3363 * src/Makefile.am: Unconditionally build the GIF loader.
3365 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3367 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
3368 Added a lot of comments to the file.
3370 * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
3373 1999-11-03 Michael Fulbright <drmike@redhat.com>
3375 * src/io-jpeg.c (image_load_increment): Further removal of
3376 bugginess in local buffering code. Handles grayscale jpegs
3379 * src/io-jpeg.c (image_load_stop): Was freeing local context
3380 for jpeg library before calling jpeg_decompres_finish ().
3382 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3384 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
3386 (gif_get_lzw): set the transparency to the right val.
3388 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3390 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
3391 Initiailize the x and y fields.
3392 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
3393 (PixbufPrivate): Renamed need_size_update to need_xform_update.
3394 (recompute_bounding_box): Do not use temporary values.
3396 1999-11-03 Jonathan Blandford <jrb@redhat.com>

3401 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): remove
3402 unneeded x,y,h,w vars.
3404 1999-11-03 Larry Ewing <lewing@gimp.org>
3406 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
3407 render_affine calculation for x,y offsets.
3408 (gnome_canvas_pixbuf_set_arg): add x,y args.
3409 (gnome_canvas_pixbuf_get_arg): add x,y args.
3410 (recompute_bounding_box): simply code using ArtDrect and the
3411 render_affine. Removed compute_xform_vectors as it was no longer
3414 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3416 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
3417 doofus. Return a distance, not a boolean, for opaque images.
3419 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
3420 rounding of bounding box coordinates.
3421 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
3422 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
3424 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3426 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
3428 1999-11-03 Michael Fulbright <drmike@redhat.com>
3430 * src/io-jpg.c (image_load_increment): Fixed code which moved
3431 buffer around as new data comes in to work properly. JPEG progressive
3432 loading should be working now except for grayscale JPEG's, which I
3433 will look into next.
3435 1999-11-03 <sopwith@redhat.com>
3436 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
3437 Also put dot printing back in.
3439 1999-11-03 <jrb@redhat.com>
3441 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
3444 1999-11-02 Cody Russell <bratsche@dfw.net>
3445 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
3446 if part of the requested image is offscreen, rather than clipping
3449 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3451 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
3452 for interlacing and progressive loading.
3454 1999-11-02 Cody Russell <bratsche@dfw.net>
3455 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
3456 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
3458 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3460 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
3461 It's a little slow though. )-:
3463 1999-11-02 Elliot Lee <sopwith@redhat.com>
3464 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
3465 write/load_increment operations const-correct.
3467 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3469 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
3470 Implemented the ::point() method. We do a simple containment test
3471 instead of a full distance calculation since the canvas is going
3472 to change to that scheme, anyways.
3474 1999-11-02 Elliot Lee <sopwith@redhat.com>
3476 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
3477 that are read from the input file.
3479 1999-11-02 Larry Ewing <lewing@gimp.org>
3481 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
3483 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
3486 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3488 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3489 affine computation code from ::draw() to here, since it is needed
3490 by ::point() as well.
3492 1999-11-02 Elliot Lee <sopwith@redhat.com>
3494 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3495 three functions, and eliminate duplication of code from write()
3496 and close(). Also fix bug where the 128-byte header was being
3499 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3500 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3501 bounding box computation.
3503 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3505 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3506 Drawing affines seem to work. Bounding box is fubared. ::point()
3507 is not implemented. This is a work in progress.
3509 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3512 * configure.in: Sigh. We need to link in libgnomeui for the
3513 canvas stuff. This mess will disappear when gdk-pixbuf gets
3514 folded into gnome-libs.
3516 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3518 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3519 the right size, at a minimum, even if the image is squished and
3521 (ReadImage): lets get the offset right. This will let transparent
3524 1999-10-29 Michael Fulbright <drmike@redhat.com>
3526 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3527 image width was not a multiple of 4 - always use the
3528 gdk_pixbuf rowstride to increment pointers!
3530 1999-10-29 Michael Fulbright <drmike@redhat.com>
3532 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3533 Currently does not handle either progressive jpeg files (jpeg
3534 files with multiple scans at different quality settings), but
3535 I plan on adding this support soon. These are fairly rare in
3536 my experience, so it shouldn't slow people down too much.
3537 Grayscale jpegs also don't work but that should be easy to fix.
3539 1999-10-29 Michael Fulbright <drmike@redhat.com>
3541 * src/testpixbuf.c: Added title to windows so you can identify
3542 progressive and file windows.
3544 1999-10-29 Michael Fulbright <drmike@redhat.com>
3546 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3547 load the image handler when we determine the image type.
3549 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3550 previously static function load_image_handler () to
3551 a public function gdk_pixbuf_load_module (). It is needed in
3552 gdk-pixbuf-loader.c to load image handler modules. This function
3553 is different from gdk_pixbuf_get_module (), which only returns
3554 a reference to the required handler, because it actually loads
3555 the handler into memory. Both actions should possibly be combined
3556 in a convenience function since one w/o the other doesn't seem to
3559 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3561 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
3564 1999-10-28 Federico Mena Quintero <federico@redhat.com>
3566 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3567 function to render a portion of a pixbuf to a drawable. Ignores
3568 alpha information and takes in a GC.
3569 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3570 portion of a pixbuf to a drawable. It automatically creates a GC
3571 and a clipping mask for alpha pixbufs.
3573 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3575 * src/gdk-pixbuf.h: turned convenience macros into convenience
3576 functions so some error checking could be added.
3578 * src/io-tiff.c (image_load_increment): started work on the tiff
3579 non-incremental loader.
3580 (image_begin_load): Finished the incremental loader.
3582 * src/io-gif.c (image_load_increment): started work on the gif
3585 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
3587 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3589 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3590 function to threshold a pixbuf's alpha channel into a bitmap.
3592 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3593 contemplate future extensions to ArtPixBuf's formats.
3595 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3597 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3598 macros to fetch the ArtPixBuf's fields.
3600 1999-10-27 Havoc Pennington <hp@pobox.com>
3602 * src/testpixbuf.c (main): Display the progressive load
3604 * src/io-png.c (setup_png_transformations): Break transformation
3605 code into separate function
3606 (png_info_callback): Use setup_png_transformations
3608 1999-10-27 Havoc Pennington <hp@pobox.com>
3610 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3611 properly whether the XPM module has already been loaded
3612 (gdk_pixbuf_new_from_file): Check properly if loader module
3613 was already loaded (was checking if load symbol was present
3614 in order to decide whether to re-load; should check module !=
3615 NULL, then load != NULL)
3616 (image_handler_load): Check in present working directory,
3617 makes it easier to debug for now
3618 (file_formats): This array initializer was seriously on crack,
3619 was assigning a function pointer to a GModule*
3621 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
3623 1999-10-27 Havoc Pennington <hp@pobox.com>

3638 class destroy function.
3639 (gdk_pixbuf_loader_new): Documented.
3640 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3642 (gdk_pixbuf_loader_write): Use size_t for count.
3644 1999-10-27 Michael Fulbright <drmike@redhat.com>
3646 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3647 logic so we only try to close loader if it wasn't previously closed.
3649 1999-10-27 Michael Fulbright <drmike@redhat.com>
3651 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of
3652 pixbuf_loader properly initialized.
3654 * src/testpixbuf.c: Made sure we cleanup pixbuf_loader properly
3657 1999-10-26 Jonathan Blandford <jrb@redhat.com>

3675 1999-10-25 Federico Mena Quintero <federico@redhat.com>
3677 * configure.in (CFLAGS): Patch from Uwe Koloska
3678 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3680 1999-10-22 Havoc Pennington <hp@pobox.com>
3682 * src/io-xpm.c (mem_buffer): Clean up stupid
3683 increment-inside-array-dereference thing
3685 * src/testpixbuf.c: Add XPM data tests.
3687 * src/io-xpm.c: Make the XPM data buffer const, fix const
3688 correctness throughout the code.
3690 1999-10-22 Havoc Pennington <hp@pobox.com>
3692 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

3700 function, loads pixbuf from xpm data
3701 (image_handler_load): Add g_return_if_fail() to ensure the same
3702 module isn't loaded twice. Add g_module_symbol() to scan for XPM
3705 1999-10-22 Federico Mena Quintero <federico@redhat.com>
3707 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3708 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
3709 buffers; the rows can be read in directly into the main pixel
3712 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3714 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
3716 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3718 * configure.in: Bumped version number to 0.3.
3720 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
3721 version number for the library.
3723 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3725 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
3726 all memory management of the buffer is done by libart.
3728 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
3729 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
3731 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
3732 terms of the libart functions. Removed the old code.
3734 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
3735 symbols. Saving will not be implemented in GdkPixbuf.
3737 * src/io-gif.c: Removed the saving stub.
3738 (image_load): Fixed memory management to fail gracefully if we run
3739 out of memory while loading the image. Close the gif file when we
3740 are done. This still needs more error handling for the DGif
3743 * src/io-jpeg.c (image_load): Some robustness fixes.
3745 * src/io-png.c: Removed the saving stuff.

3756 * autogen.sh: use subautogen.sh
3758 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3760 * src/*: Reindented to use the GNOME Indentation. Renamed
3761 GdkPixBuf to GdkPixbuf, for consistency with the function names
3762 (and it is also easier to type) :-)
3764 1999-10-18 Havoc Pennington <hp@pobox.com>
3766 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
3768 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS

3778 comment out testpixbuf for now
3780 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3782 * configure.in: Use $GTK_LIBS as the extra libs when checking for
3783 libgif/libungif, as they need the X libraries. Fixes bug #2472.
3785 1999-10-10 Cody Russell <bratsche@dfw.net>
3786 * src/gdk-pixbuf-drawable.c: core function now determines whether
3787 the requested geometry is on screen or not, and if some is not
3788 then the request is clamped to geometry that is on the screen.
3790 Changed 'pixbuf' to 'art_pixbuf' in core function.
3792 1999-10-08 Michael Fulbright <drmike@redhat.com>
3794 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

3797 if no filename given to test program.
3799 1999-10-07 Cody Russell <bratsche@dfw.net>
3800 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed

3871 * src/gdk-pixbuf-io.c: Likewise.
3873 Sat Jul 31 19:19:47 CEST 1999

3876 * src/io-png.c: Fixed two obvious C syntax bugs
3878 1999-07-29 Mark Crichton <crichton@gimp.org>
3880 * src/io-png.c (image_save): Added PNG saving function

3886 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
3888 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3889 require extra libraries if we actually have those libraries.
3891 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3893 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
3894 * gdk_pixbufConf.sh.in: Added for gnome-config
3896 * configure.in: Modified to generate gdk_pixbufConf.sh
3898 1999-07-20 Mark Crichton <crichton@gimp.org>
3900 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3901 calculation needs to be done.
3903 1999-07-18 Larry Ewing <lewing@gimp.org>
3908 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3909 error cases but one or two in the common case. There are probably
3910 a few small ones left.
3912 1999-07-18 Mark Crichton <crichton@gimp.org>
3914 * configure.in: removed version.h.
3916 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3919 1999-07-17 Mark Crichton <crichton@gimp.org>

3930 * src/testpixbuf.c (expose_func): reverted the expose everything
3931 changes, I'm not sure why these went in.
3932 (config_func): bring this up to date with the new pixbuf_scale
3935 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3936 loading code so that poeple can diagnose problems better.
3938 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3939 no longer allocates a new pixbuf, which make things nicer for the
3940 rest of the code. Unfortunately there is still a problem with
3941 scaling rgba images.
3943 1999-07-16 Mark Crichton <crichton@gimp.org>
3945 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3946 calls gdk_pixbuf_scale. However, something is not working.
3947 N.B.: current pixmap is now stored in user_data with a key of
3950 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
3951 Something is still borked, however.

3959 that you can load multiple files given the file names
3961 1999-07-14 Larry Ewing <lewing@gimp.org>
3963 * src/testpixbuf.c (expose_func): added an almost proper expose
3964 handler for testpixbuf
3966 1999-07-13 Mark Crichton <crichton@gimp.org>
3968 * configure.in: Fixed GIF check. Replaced " with '
3969 * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale
3971 1999-07-13 Mark Crichton <crichton@gimp.org>
3973 * configure.in: I am a bonehead. Added gif-lib check.
