536 the "put" routine. (Fixes #87384)
537 (gdk_pixbuf__tiff_image_stop_load): Don't call TIFFClose too
540 2002-07-02 Matthias Clasen <maclas@gmx.de>
542 Miscellaneous bmp loader fixes (#85448, #86286, #86287):
544 * io-bmp.c (grow_buffer): New function to avoid crashes
545 on unchecked reallocs.
546 (DecodeHeader, DecodeColormap, decode_bitmasks,
547 DoCompressed): Use grow_buffer instead of g_realloc
548 throughout. Change signatures where necessary to pass the
550 (OneLine16): Fix loading of 16bpp BI_RGB bmps.
551 (DoCompressed): Rewritten to properly support BI_RLE4 and
554 Support for compressed ras images (#84994):
556 * io-ras.c (RAS2State): Error on unsupported ras variations.
557 (OneLine8): Fix colormap indexing.
558 (OneLine): Call updated_func with proper region.
559 (DoCompressed): New function, handles compressed ras data.
560 (gdk_pixbuf__ras_image_load_increment): Handle compressed ras
563 Better colorspace support for the jpeg loader (#61211):
565 * io-jpeg.c (convert_cmyk_to_rgb): New function.
566 (gdk_pixbuf__jpeg_image_load,
567 gdk_pixbuf__jpeg_image_load_increment): Allocate a pixbuf with
568 alpha for 4-channel jpegs and call convert_cmyk_to_rgb for these.
570 All of this needs to be merged to GNOME 1.4 gdk-pixbuf.
572 2002-06-28 Sven Neumann <sven@gimp.org>
574 * gdk-pixbuf-csource.c (print_blurb): converted a Tab to spaces.
576 Thu Jun 13 18:11:11 2002 Owen Taylor <otaylor@redhat.com>
578 * pixops/pixops.c: Fix problem where when no alpha was
579 involved, we scaled rather than composited, but then
580 went ahead and composited anyways. (#76958, Patch
581 from Matthias Clasen). Needs to be merged to GNOME
584 2002-06-13 Matthias Clasen <maclas@gmx.de>
586 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
587 incrementally display incrementally loaded progressive jpegs.
589 2002-06-07 Federico Mena Quintero <federico@ximian.com>
592 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
593 starting at a specific memory location. We do this instead of
594 GINT32_FROM_LE() as the latter is simply dereferences a cast,
595 which doesn't work on platforms with alignment requirements.
598 2002-06-01 Matthias Clasen <maclas@gmx.de>
600 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
601 with a C comment - those seem to be not uncommon, e.g. the Gimp
602 produces them. (#82706)
604 * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
606 (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.
608 2002-05-22 Tor Lillqvist <tml@iki.fi>
610 * gdk-pixbuf-io.c (get_libdir): Use GTK_BINARY_VERSION (and not
611 GTK_VERSION) in the path to the loaders on Win32, too.
613 * Makefile.am: Pass GTK_BINARY_VERSION.
615 2002-05-22 Federico Mena Quintero <federico@ximian.com>
617 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
618 account!!! Fixes #82515.
620 [This bug is not present in the GNOME 1.4 branch as its XPM loader
621 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
622 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
624 [IMPORTANT: The comment above is to make my life easier when
625 merging stuff across branches. If you make changes to gdk-pixbuf
626 in either branch, please include a comment in the ChangeLog that
627 indicates whether this should be merged into the other branch.
630 2002-05-18 Matthias Clasen <maclas@gmx.de>

645 2002-05-07 Michael Natterer <mitch@gimp.org>
647 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
648 conditionally like the dynamic ones so --without-lib<foo> is
649 honored when building with --disable-modules. (#66867)
651 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
653 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to
655 * test-loaders.c, test-images.h: remove
657 2002-04-24 Matthias Clasen <maclas@gmx.de>
659 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
660 restriction from the description of png tEXt parameters.
662 * io-png.c (png_text_to_pixbuf_option):
663 (gdk_pixbuf__png_image_save): If libpng supports it,
664 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
666 2002-04-11 Matthias Clasen <maclas@gmx.de>
668 More fixes for #77807:
670 * io-tga.c (get_contiguous_pixbuf): Helper function to create
671 a pixbuf with a contiguous pixel array while being careful about
674 * io-tga.c (fill_in_context, get_image_pseudocolor,
675 get_image_truecolor, get_image_grayscale): Use
676 get_contiguous_pixbuf instead of manually allocating image
679 * io-xpm.c (pixbuf_create_from_xpm):
680 * io-pnm.c (gdk_pixbuf__pnm_image_load):
681 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
682 instead of manually allocating image storage.
684 2002-04-09 Matthias Clasen <maclas@gmx.de>
686 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
687 priv->image_module->module_name instead of image_type which may
690 2002-04-06 Matthias Clasen <maclas@gmx.de>
692 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
693 gdk_pixbuf_new instead of manually allocating image storage. This
694 gives us a good rowstride and overflow checks. (#77807)
696 2002-04-05 Matthias Clasen <maclas@gmx.de>
698 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
699 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable
700 put functions instead of TIFFRGBAImage. And check image dimensions

707 2002-03-29 Matthias Clasen <maclas@gmx.de>
709 * io-png.c (png_simple_error_callback): libpng error handlers must
710 not return to their callers, thus longjmp out. This prevents
711 annoying stderr output from the default error handler.
713 2002-03-27 Matthias Clasen <maclas@gmx.de>
715 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
717 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
718 end_info. Also call png_read_end to check proper ending of the png
719 file and catch text chunks after the image data.
721 2002-03-27 Matthias Clasen <maclas@gmx.de>
723 * io-png.c (gdk_pixbuf__png_image_load,
724 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
725 instead of system malloc.
727 2002-03-26 Matthias Clasen <maclas@gmx.de>
729 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
731 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
732 context->buf on error.
734 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
735 stop_load even for short images to prevent memleaks.
737 2002-03-25 Matthias Clasen <maclas@gmx.de>
739 * io-png.c (setup_png_transformations): Changed signature to
740 return success and set a GError parameter, adjusted all callers.
741 Also work around a possible FPE in libpng and always check that
742 the new info is sane.
744 2002-03-23 Matthias Clasen <maclas@gmx.de>
746 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
747 context->updated_func is NULL during a nonincremental load.
748 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
750 2002-03-18 Matthias Clasen <maclas@gmx.de>
752 * io-tga.c: Fix assumptions on rowstride by manually allocating a
753 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
754 Support grayscale + alpha (which can be written, but not read (!)
757 2002-03-15 Matthias Clasen <maclas@gmx.de>
759 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
761 2002-03-13 Matthias Clasen <maclas@gmx.de>
763 * test-images.h: Add valid_ras_test and invalid_bmp_1.
765 * test-loaders.c (main): Add random tests for ras and pnm and an
766 invalid bmp which was a crasher until my 2002-03-12 commit.
768 * io-pnm.c (gdk_pixbuf__pnm_image_load_increment): Don't unref the
771 * io-ras.c: Handle some errors.
773 2002-03-12 Sven Neumann <sven@gimp.org>
775 * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
776 calling memcpy(). Simpler and potentially faster. (#70332)
778 2002-03-12 Matthias Clasen <maclas@gmx.de>
780 * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
781 which could actually be reached by a proper error status return.
783 2002-03-05 Matthias Clasen <maclas@gmx.de>
785 * test-loaders.c, test-images.h: More random tests.
787 * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.

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

802 rather than .libs, so we find the right .la files.
804 * test-loaders.c: Back out some accidental commits.
806 Sat Mar 2 21:28:03 2002 Owen Taylor <otaylor@redhat.com>
808 * gdk-pixbuf.c (gdk_pixbuf_new): Bullet-proof against integer

848 * test-images.h (tiff1_test_3), test-loaders.c (main): Add a
849 (#ifdef 0'ed) test provoking a segfault in TIFFReadDirectory().

1094 2001-10-29 Tor Lillqvist <tml@iki.fi>
1096 * Makefile.am: Use -no-undefined on Win32. Make
1097 libgdk_pixbuf_1_3_la_OBJECTS depend on
1098 gdk-pixbuf-marshal.c. Install import libraries.
1100 * gdk_pixbuf.def: Update.
1102 * gdk-pixbuf-io.c: (Win32) Use G_WIN32_DLLMAIN_FOR_DLL_NAME, saves
1103 the actual DLL name of libgdk_pixbuf.
1104 (get_libdir): Use it instead of guessing.
1106 * io-xbm.c (gdk_pixbuf__xbm_image_begin_load): Use
1107 g_file_open_tmp() insread of mkstemp().
1109 2001-10-18 Matthias Clasen <matthiasc@poet.de>
1111 * io-xbm.c (gdk_pixbuf__xbm_image_load_real): Don't dereference
1112 context when it may be NULL. (#62344)
1114 2001-10-16 Matthias Clasen <matthiasc@poet.de>
1116 * gdk-pixdata.c, gdk-pixdata.h: Documentation.
1118 * gdk-pixbuf-csource.1: Spelling fixes.
1120 Wed Oct 10 11:52:17 2001 Owen Taylor <otaylor@redhat.com>
1122 * gdk-pixdata.c gdk-pixbuf.h: Get rid of
1123 GDK_PIXBUF_ERROR_HEADER/PIXEL_CORRUPT and use CORRUPT_IMAGE.
1124 Get rid fo GD_PIXBUF_ERROR_UNKNOWN_FORMAT and use the
1125 existing UKNOWN_TYPE error. (#58308)
1127 * gdk-pixbuf.h, gdk-pixdata.c: Rename gdk_pixbuf_new_from_stream()
1128 back to gdk_pixbuf_new_from_inline(). Rework docs to try
1129 and be helpful for the common case. (#58308)
1131 2001-10-05 Sven Neumann <sven@gimp.org>
1133 * gdk-pixbuf/gdk-pixbuf-io.c
1134 * gdk-pixbuf/gdk-pixbuf-private.h
1135 * gdk-pixbuf/gdk-pixbuf.c
1136 * gdk-pixbuf/gdk-pixbuf.h
1137 * gdk-pixbuf/io-jpeg.c
1138 * gdk-pixbuf/io-png.c: changed GDK_PIXBUF_ERROR_BAD_OPTION_VALUE to
1139 GDK_PIXBUF_ERROR_BAD_OPTION to we can use it for bad keys too. Added
1140 new public API gdk_pixbuf_get_option() to retrieve key/value pairs
1141 set by an image loader. Added support for saving and reading PNG tEXt
1142 chunks in PNG images.
1144 Tue Oct 2 11:29:50 2001 Owen Taylor <otaylor@redhat.com>
1146 * gdk-pixdata.c (gdk_pixdata_to_csource): Fix indentation
1147 use a macro to make code a bit more readable.
1149 2001-10-02 Sven Neumann <sven@gimp.org>
1151 * gdk-pixdata.c: g_string_printfa => g_string_append_printf.
1153 Wed Sep 26 18:08:19 2001 Owen Taylor <otaylor@redhat.com>
1155 * Makefile.am (s-enum-types-h): Fix a typo in the include
1156 guards. (#61254, Skip Montaro)
1158 2001-09-21 Matthias Clasen <matthiasc@poet.de>
1160 * io-xpm.c (xpm_extract_color): Rewritten to handle
1161 xpm colormap entries more thoroughly. (#59939)
1163 2001-09-21 Hans Breuer <hans@breuer.org>
1165 * gdk-pixbuf.def : updated externals
1167 * makefile.msc : generate gdk-pixbuf-enum-types.[hc]
1169 Thu Sep 20 17:22:48 2001 Owen Taylor <otaylor@redhat.com>
1171 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
1172 works in some on-demand way, so the fseek
1173 gdk_pixbuf_new_from_file() doesn't work here since we are using
1174 the raw file descriptor. So, we call lseek() on the fileno(f)
1175 before using it. (#60840).
1177 2001-09-20 James Henstridge <james@daa.com.au>
1179 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
1180 so that flags types are registered as flags rather than enums (not
1181 that there are any flags here at the moment).
1183 Wed Sep 19 00:28:24 2001 Owen Taylor <otaylor@redhat.com>
1185 * Makefile.am (gdk_pixbuf_headers): Don't include
1186 gkd-pixbuf-features.h here since is in builddir
1187 and confuses autogen rules.
1189 * Makefile.am: Don't += variables before they have values,
1190 automake-1.5 doesn't like it.
1192 * Makefile.am: Fix srcdir != builddir for gdk-pixbuf-enum-types.c.
1194 * Makefile.am: The whitespace strikes back.
1196 2001-09-17 Matt Wilson <msw@redhat.com>
1198 * Makefile.am (libpixbufloader_xbm_la_LDFLAGS): removed duplicate
1199 LDFLAGS definition, use the -avoid-version one.
1200 (libpixbufloader_tga_la_LDFLAGS): likewise
1202 Mon Sep 17 11:49:02 2001 Owen Taylor <otaylor@redhat.com>
1204 * pixops/*: Mirror GdkInterpType to PixopsInterpType
1205 to avoid including gdk-pixbuf headers.
1207 2001-09-16 James Henstridge <james@daa.com.au>
1209 * .cvsignore: add generated files to ignore list.
1211 * gdk-pixbuf.h: include gdk-pixbuf-enum-types.h
1213 * Makefile.am: add rules to build gdk-pixbuf-enum-types.[ch]
1215 Fri Sep 14 23:22:12 2001 Matthias Clasen <matthiasc@poet.de>
1217 * io-pnm.c (pnm_read_header): Use GDK_PIXBUF_ERROR_CORRUPT_IMAGE,
1218 not GDK_PIXBUF_ERROR_HEADER_CORRUPT. (#58308)
1220 Fri Sep 14 22:53:45 2001 Matthias Clasen <matthiasc@poet.de>
1222 * io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load): Handle
1223 out-of-memory situation better.
1225 * io-pnm.c: Robustness fixes for pnm loader
1227 * io-gif.c: Make gif loader survive TEST_RANDOMLY_MODIFY
1229 * io-xpm.c (parse_color): detect very long color strings
1231 All of the above from Matthias Clasen <matthiasc@poet.de>,
1232 the remaining from Soeren Sandmann <sandmann@daimi.au.dk>.
1234 * test-images.h: add tests:
1235 - four valid ppm's, eight invalid (matthiasc@poet.de)
1236 - one invalid xpm (matthiasc@poet.de)
1237 - one valid tga, one invalid (sandmann@daimi.au.dk)
1238 - one invalid tiff (sandmann@daimi.au.dk
1240 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
1242 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
1243 fail - detect it when it happens
1245 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
1248 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
1251 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
1253 * Makefile.am: don't used BUILT_SOURCES to build marshal
1254 files, as in conjunction with stamp files, this can
1255 lead to endless rebuilding loops.
1257 Tue Sep 4 00:22:07 2001 Owen Taylor <otaylor@redhat.com>
1259 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1
1261 Tue Sep 4 03:09:52 2001 Tim Janik <timj@gtk.org>
1263 * gdk-pixbuf-csource.1: new file, manual page for
1264 the publically installed gdk-pixbuf-csource utility.
1266 Thu Aug 30 08:30:03 2001 Matthias Clasen <matthiasc@poet.de>
1268 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Propagate
1269 errors from gdk_pixbuf_loader_load_module.
1271 Thu Aug 30 08:27:37 2001 Matthias Clasen <matthiasc@poet.de>
1273 * io-png.c (png_row_callback): Check that row_num is valid.
1275 Tue Aug 28 21:05:26 2001 Matthias Clasen <matthiasc@poet.de>
1277 * io-bmp.c (OneLine): Emit area_updated signal with proper
1278 area information. (#52002)
1280 Tue Aug 28 20:03:43 2001 Matthias Clasen <matthiasc@poet.de>
1282 * test-loaders.c (test_loader): Catch errors at close time.
1283 * test-loaders.c (main): Remove C++ comments.
1285 2001-08-21 Matthias Clasen <matthiasc@poet.de>
1287 * Makefile.am, gdk-pixbuf-io.c, pixbufloader_tga.def,
1288 io-tga.c: Add tga loader, patch by Nicola Girardi. (#56067)
1290 2001-08-20 Matthias Clasen <matthiasc@poet.de>
1292 * test-images.h, test-loaders.c: Add ico and wbmp tests.
1293 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): Fail with a suitable
1294 error if buffer allocation fails.
1295 * io-ico.c: Make .ICO loader more robust.
1296 All of these are due to sandmann@daimi.au.dk (#50187)
1298 2001-08-19 Sven Neumann <sven@gimp.org>
1300 * pixops/pixops.c: applied some simple but effective optimizations
1301 to pixops_composite_nearest() and pixops_composite_color_nearest().
1303 2001-08-07 Sven Neumann <sven@gimp.org>
1305 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
1306 function, so that's what I did.
1308 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
1310 * gdk-pixdata.c: Fix a typo.
1312 2001-07-30 Hans Breuer <hans@breuer.org>
1314 * pixops/makefile.msc : new file
1315 * makefile.msc : use it to complete the build
1317 2001-07-20 Hans Breuer <hans@breuer.org>
1319 * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
1320 pointer increment out of the macro, because at least one
1321 compiler (msvc 5.0) gets confused otherwise (applies the
1324 * gdk_pixbuf.def : updated exports
1326 * makefile.msc : reflect gdk-pixbuf-csource changes
1328 2001-07-17 Darin Adler <darin@bentspoon.com>
1330 * gdk-pixbuf-csource.c: Add missing <stdlib.h> include.
1331 * io-png.c: (setup_png_transformations): Add ifdef so we compile
1332 without warnings with G_DISABLE_CHECKS on.
1333 * io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
1335 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
1336 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
1337 unused locals and add an initial value to quiet the compiler's
1338 unintialized variable warning.
1339 * pixops/pixops.c: Put an ifdef around some dead code.
1341 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
1343 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
1344 over to the new include flags AC_SUBST(). (Problem
1345 pointed out by Mikael Hermansson.)
1347 2001-06-29 Havoc Pennington <hp@redhat.com>
1349 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): fix for
1352 Thu Jun 28 21:54:19 2001 Owen Taylor <otaylor@redhat.com>
1354 * make-inline-pixbuf.c test-gdk-pixbuf.c test-loaders.c
1355 gdk-pixbuf-csource.c: Fix args to g_type_init ().
1357 2001-06-28 Havoc Pennington <hp@pobox.com>
1359 * gdk-pixdata.c: <string.h>
1361 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
1362 also leaking memory here from g_strdup_printf?)
1364 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
1366 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
1368 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
1369 instead from gdk_pixbuf_new_from_inline().
1371 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
1372 installed API for applications that need to serialize/deserialize
1373 on their own (gimp, BEAST).
1375 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
1376 program that can dump images in CSource format and Pixbuf
1377 stream format. supports RLE encoding, MACRO formatting etc...
1380 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
1382 * Makefile.am: Actually update timestamps, so rules don't
1385 2001-06-11 Havoc Pennington <hp@redhat.com>
1387 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
1388 already includes top_builddir
1390 2001-06-08 Havoc Pennington <hp@redhat.com>
1392 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
1393 bogus g_return_if_fail
1395 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
1396 likely timeout resolution, set it to an arbitrarily-chosen short
1398 Fixes bug #55953 from warmenhoven@yahoo.com
1400 2001-06-07 Havoc Pennington <hp@redhat.com>
1402 * Makefile.am: use Owen's new way of doing stampfiles/generated
1405 2001-06-07 Havoc Pennington <hp@redhat.com>

1409 2001-06-05 Havoc Pennington <hp@redhat.com>
1411 * test-loaders.c (main): use putenv not setenv, reported by
1414 2001-05-08 Havoc Pennington <hp@redhat.com>
1416 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1417 and fix behavior to still subst color if the original image
1420 2001-06-04 Havoc Pennington <hp@redhat.com>
1422 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1425 2001-06-01 Havoc Pennington <hp@redhat.com>
1427 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1428 Makes things a bit more robust, and adds test-loaders.c
1429 which is good for finding further robustness bugs to fix.
1431 * io-tiff.c: Try to work around libtiff suckiness a bit;
1432 put a giant thread lock on the whole loader,
1433 paranoically check both whether error handlers were called and
1434 also whether functions return false. Handle case where width or
1435 height is 0. Various cleanups.
1437 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1439 (png_error_callback): apparently libpng expects you to longjmp out
1442 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1443 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1445 (gif_get_lzw): check for out-of-memory
1446 (gif_prepare_lzw): catch/report an error
1447 (new_context): use try_malloc, since GifContext is nearly 70K
1448 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1449 so we don't crash later.
1451 * Makefile.am: Add test-loaders
1453 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1456 2001-05-29 Darin Adler <darin@eazel.com>
1458 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1460 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1462 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1463 fix up bmp decoder to:
1464 - adds 16 bpp bmp support (bug #53884)
1465 - adds OS/2 1.x format bmp support (bug #54964)
1466 - adds 4 bpp RLE compressed bmp support
1467 - adds 1 bpp colormap support
1468 - fixes negative height (top down) bmp support
1470 2001-05-25 Hans Breuer <hans@breuer.org>
1472 * gdk_pixbuf.def : reflect Havoc's recent api change
1474 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1476 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1477 excess $(GLIB_LIBS).
1479 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1481 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1483 2001-05-04 Havoc Pennington <hp@redhat.com>
1485 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1486 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1489 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1490 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1491 confusion of using "src" instead of "p".
1492 (pixops_composite_color_nearest): Use a more accurate (and
1493 correct, to begin with) compositing method. This cures checks
1494 showing through on images with no alpha.
1496 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1499 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1501 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1502 area_updated signal to use signed ints. Removed animation-related
1505 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1508 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1509 all the pesky details. Remove old frame-based API. Make
1510 GdkPixbufAnimation an abstract base class, derived by the loaders.
1512 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1514 * Makefile.am (LDADDS): Add $(MATH_LIB).
1516 2001-04-18 Havoc Pennington <hp@redhat.com>
1518 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1521 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1523 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1524 so we don't try to get <gtk/gtkobject.h> from standard search
1527 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1528 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1529 take gdk-pixbuf-marshal.h out of _la sources.
1531 2001-03-19 Tor Lillqvist <tml@iki.fi>
1533 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1535 * gdk_pixbuf.def: Update.
1537 * pixbufloader_*.def: Just export the fill_vtable functions now.
1539 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1541 * make-inline-pixbuf.c (main): Added logic to remove output when
1544 2001-03-14 Havoc Pennington <hp@redhat.com>
1546 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1547 from gdk-pixbuf-marshal.h, fixes parallel makes.
1549 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1551 * test-gdk-pixbuf.c: fixed includes.
1553 2001-02-18 Havoc Pennington <hp@pobox.com>
1555 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1556 (gdk_pixbuf_get_named_module): prepend underscore
1557 (gdk_pixbuf_get_module): prepend underscore
1559 2001-02-19 Havoc Pennington <hp@redhat.com>
1561 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1563 2001-02-17 Havoc Pennington <hp@pobox.com>
1565 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1567 2001-02-07 Alexander Larsson <alexl@redhat.com>
1569 * io-xpm.c (free_buffer):
1570 Use g_free, since the buffer is allocated with g_try_alloc().
1572 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1574 * gdk-pixbuf-data.c: Fixes a minor typo.
1576 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1578 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1579 we finally need the gobject->gruntime rename.
1581 * *.c: scratched calls to g_type_init(), there's simply no point in
1582 doing that, use gtk_init().
1584 2001-02-01 Havoc Pennington <hp@pobox.com>
1586 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1587 in struct to "priv" for C++
1589 2001-01-31 Havoc Pennington <hp@pobox.com>
1591 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1593 2001-01-26 Havoc Pennington <hp@redhat.com>
1595 * gdk-pixbuf-io.c (mname): fix included modules case.
1597 2001-01-22 Havoc Pennington <hp@redhat.com>
1599 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1600 from gdk_pixbuf_load_module
1602 2001-01-22 Havoc Pennington <hp@redhat.com>
1604 * Makefile.am: Add built marshaller files to support
1605 GdkPixbufLoader signals
1607 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1608 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1609 module location, rather than acting as a fallback, because we are
1610 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1612 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1614 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1615 from gtk, and add error to close(), because stop_load may do
1616 parsing of the image.
1618 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1620 * io-*.c: make individual operations static, and add fill_vtable
1621 functions which are exported. Fix the collection of type warnings
1622 that surfaced, including a number of functions that didn't
1623 properly take a GError and some that weren't
1624 const-correct. Involved adding error handling for a few loaders.
1626 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1628 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1629 a function that fills in the GdkPixbufModule vtable, instead of
1630 looking up all the image functions individually; this means we
1631 can get type safety within modules for the loader functions.
1632 Also it means you don't have to keep the statically compiled and
1633 GModule versions in sync.
1635 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1637 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1639 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1641 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1644 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1646 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1649 2001-01-20 John Harper <jsh@eazel.com>
1651 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1652 collision between Xlib's RdBitF.c and io-tiff.c
1654 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1657 [ merged from stable gdk-pixbuf module. Untested, but it
1658 compiles, and works fine in the stable module ]
1660 2001-01-18 Tor Lillqvist <tml@iki.fi>
1662 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1663 g_win32_get_package_installation_subdirectory() function. No need
1664 to include windows.h.
1665 (gtk_win32_get_installation_directory): Remove this then.
1667 2001-01-01 Havoc Pennington <hp@redhat.com>
1669 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
1670 @LIBTOOL_EXPORT_OPTIONS@
1672 2000-12-30 Tor Lillqvist <tml@iki.fi>
1674 * gdk_pixbuf.def: Update.
1676 2000-12-16 Havoc Pennington <hp@pobox.com>
1678 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1679 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1680 (gdk_pixbuf_frame_copy): new function
1681 (gdk_pixbuf_frame_free): new function
1682 (gdk_pixbuf_frame_get_type): new function
1683 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
1685 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
1687 * Makefile.am: Add -avoid-version for all modules.
1689 2000-11-13 Havoc Pennington <hp@redhat.com>
1691 * io-png.c (png_simple_error_callback): fix error message to not
1692 say "save" since it's used for loading
1694 2000-11-11 Hans Breuer <Hans@Breuer.Org>
1696 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1697 contained image handlers (!USE_G_MODULE). Files to save should
1698 be opened in binary mode, fopen(s, "wb").
1700 * io-xpm.c : added HAVE_UNISTD_H condition
1702 2000-11-11 Tor Lillqvist <tml@iki.fi>
1704 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1706 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1707 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1708 mktemp() and open()).
1710 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1712 2000-11-01 Havoc Pennington <hp@pobox.com>
1714 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1715 a pixbuf pointing to a subregion of another pixbuf.
1717 2000-10-16 Tor Lillqvist <tml@iki.fi>
1719 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1721 2000-10-16 Havoc Pennington <hp@redhat.com>
1723 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1724 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1725 add error reporting here also
1727 * make-inline-pixbuf.c (main): use GError
1729 * io-xpm.c: include unistd.h
1731 * gdk-pixbuf-util.c: include string.h
1733 * io-*.c: add error reporting
1735 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
1738 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
1740 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1743 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1744 a G_FILE_ERROR if we fail to write or close the file.
1746 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1747 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1748 the GError naming rules. Add GError** to load functions.
1750 2000-10-06 Havoc Pennington <hp@redhat.com>
1752 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1754 2000-10-06 Havoc Pennington <hp@redhat.com>

1782 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
1784 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
1785 last nights code was still "broken". Should now properly handle
1786 all error conditions gracefully.
1788 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
1790 * gdk-pixbuf/io-pnm.c: Rewrote.
1792 2000-09-09 Federico Mena Quintero <federico@helixcode.com>
1794 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
1795 the correct dest offset.
1797 2000-08-25 Federico Mena Quintero <federico@helixcode.com>
1799 * gdk-pixbuf/io-xpm.c: #include <unistd.h>
1801 2000-08-05 Larry Ewing <lewing@helixcode.com>
1803 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
1805 * gdk-pixbuf/io-xpm.c: same as above.
1807 2000-07-26 Michael Meeks <michael@helixcode.com>
1809 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
1812 2000-07-21 Larry Ewing <lewing@helixcode.com>
1814 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
1815 xpm at least supports the progressive interface like the one in
1816 io-tiff.c. This should be reimplemented as an actual progressive
1819 2000-07-19 Jonathan Blandford <jrb@redhat.com>
1821 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
1822 make it look better.
1823 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
1824 meeks to handle errors better.
1826 2000-10-07 Tor Lillqvist <tml@iki.fi>
1829 * pixbufloader_jpeg.def
1830 * pixbufloader_png.def: Add new entry points.
1832 * makefile.mingw.in: Use libintl.
1834 2000-10-06 Havoc Pennington <hp@redhat.com>
1836 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
1837 consistent with gdk_pixbuf_loader_new_with_type().
1838 Return runtime error if a module is missing.
1840 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
1842 2000-10-05 Havoc Pennington <hp@redhat.com>
1844 Pixbuf saving, patch from David Welton.
1846 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
1847 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
1849 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf
1851 * io-png.c (gdk_pixbuf__png_image_save): PNG save routine.
1853 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): JPEG save routine.
1855 * gdk-pixbuf-io.c (gdk_pixbuf_save):
1856 (gdk_pixbuf_savev): Implement pixbuf saving routines
1858 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
1861 * gdk-pixbuf.h: Add public save routines; add pixbuf error
1864 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
1866 2000-10-05 Dan Winship <danw@helixcode.com>
1868 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
1869 all three of these files are the JPEG image loader. (From
1872 2000-10-03 Tor Lillqvist <tml@iki.fi>
1874 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
1875 gdk-pixbuf's version number in the rule for makefile.mingw itself.
1877 * gdk_pixbuf.def: Add new entry points.
1879 2000-09-26 Havoc Pennington <hp@redhat.com>
1881 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
1882 function here, instead of putting it in a private GTK+ file.
1884 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
1885 enum here for the known formats of inlined pixbufs.
1886 Also, #define our file magic here.
1888 2000-06-23 Havoc Pennington <hp@redhat.com>
1890 * make-inline-pixbuf.c: Small program that creates C variable
1891 declarations of inline pixbuf data. This can be read
1892 by gdk_pixbuf_new_from_inline.
1894 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
1895 inline pixbuf data and create a pixbuf from it.
1897 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1899 2000-09-07 Tor Lillqvist <tml@iki.fi>
1901 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1904 2000-08-12 Tor Lillqvist <tml@iki.fi>
1906 * gdk_pixbuf.def: Add missing entry point.
1908 2000-08-10 Havoc Pennington <hp@redhat.com>
1910 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1911 (s/pixbuf_/pixbufloader_)
1913 2000-08-02 Tor Lillqvist <tml@iki.fi>
1919 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1921 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1922 one. Fix names of DLLs to have '-' instead of '_'.
1924 2000-07-31 Elliot Lee <sopwith@redhat.com>
1925 * io-wbmp.c: Some bug fixes - now tested to work.
1927 2000-07-27 Elliot Lee <sopwith@redhat.com>
1929 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1930 gdk_pixbuf_get_named_module() function to facilitate above change
1931 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1932 Implement loader for WBMP format.
1933 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1935 2000-07-23 Tor Lillqvist <tml@iki.fi>
1940 * pixops/makefile.mingw.in
1941 * pixbuf_*.def: New files.
1944 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1946 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1947 New function, to get the GTK+ installation directory from
1948 the Windows Registry, where the installation program
1949 for whatever software includes GTK+ has stored it.
1951 Used to avoid having hardcoding the directory where to look for
1952 loaders. This function is needed by gtk, too, so it should
1953 really be just in one place. Maybe a small static library
1954 one level up from here?
1956 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1957 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1958 Open file in binary mode. This *is* standard C. (No-op on Unix,
1961 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1963 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1964 mktemp() and open().
1965 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1967 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1968 pseudo-op. Conditionalise on __MINGW32__, but probably
1969 should conditionalise on Gas version instead? Or could we
1970 do without .type on all systems?
1972 * pixops/timescale.c: Use g_get_current_time()
1973 instead of gettimeofday().
1975 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1977 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1979 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1981 * gdk-pixbuf.c: Add <string.h> include.
1983 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1985 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1986 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1987 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1988 use g_object_new() instead of g_type_create_instance() which
1989 is a private function for fundamental type implementations.
1991 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1993 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1994 soname scheme for gdk-pixbuf.
1996 2000-06-21 Havoc Pennington <hp@pobox.com>
1998 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1999 (i.e. derivation is not allowed, and there are no virtual methods
2001 (gdk_pixbuf_preinit): Call g_type_init() here.
2002 (gdk_pixbuf_init): Add a user-friendly init function, for users
2003 of standalone gdk-pixbuf
2005 * gdk-pixbuf-animation.c: Convert to GObject, in the same
2006 way GdkPixbufAnimation was done.
2008 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
2009 gdk_pixbuf_finalize() from API, since these are broken and don't
2010 make sense with new GObject stuff.
2012 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
2014 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
2015 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
2018 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
2020 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
2021 so I needed something to warm my thighs. Running plain infinite
2022 loops on your laptop to make it hot is not very much fun. A demo
2023 of the gdk-pixbuf scaling functions is way better, and looks
2026 * configure.in (AC_OUTPUT): Added the demo Makefile.
2028 * Makefile.am (SUBDIRS): Added the demo directory.
2030 2000-06-09 Larry Ewing <lewing@helixcode.com>
2032 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
2033 setjmp for the png error handler. It seems setting the error
2034 handling functions does not avoid the jump, and so not calling
2035 setjmp was causing the incremental loader to jump into lala land.
2036 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
2037 not sure this one is actually required but the docs say it must be
2038 set for every call to a png_* function.
2039 Also changed the comment to reflect the fact that setting the
2040 error handlers does _not_ avoid the longjmp.
2042 2000-06-06 Larry Ewing <lewing@helixcode.com>
2044 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
2045 take frame offest into account when trying to calculate the
2046 animation bbox. Also set the width to the width not the height.
2047 (gdk_pixbuf_loader_animation_done): cycle over the frames to
2048 calculate bbox because now we finally have all the offset
2049 information for each frame.
2051 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
2053 * configure.in: add some gtk parameters to the
2054 GDK_PIXBUF_LIBĂƒĂ¯Â¿Â½Â²S and GDK_PIXBUG_INCLUDEDIR vars. One more
2055 fight in my crusade for strange prefix compile...
2057 2000-05-30 Not Zed <NotZed@HelixCode.com>
2059 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
2060 Initialise the error handler exit routine to our own. Note this
2061 means that every function that accesses the jpeg lib on this
2062 object MUST do a setjmp.
2063 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
2064 lib for handling fatal error.
2065 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
2066 your applications dont quit if there's a jpeg error!
2068 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
2070 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
2071 from Frank de Lange <frank@unternet.org>.
2073 2000-05-09 Darin Adler <darin@eazel.com>
2075 * gdk-pixbuf/test-gdk-pixbuf.c:
2076 Fixed includes to get rid of accidental GNOME dependency.
2078 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
2079 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
2081 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
2083 * configure.in: Bumped version number to 0.8.0.
2085 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
2086 file was not being distributed.
2088 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
2090 2000-05-09 Darin Adler <darin@eazel.com>
2092 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
2093 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
2094 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
2095 formats to 32-bit formats to re-use the high bits of the color values
2096 so that white maps to full white.
2098 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
2100 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
2101 detailed information about the structure and algorithms
2102 of pixops so people can fix it instead of breaking it.
2104 2000-05-04 Darin Adler <darin@eazel.com>
2106 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
2107 (composite_pixel), (composite_line):
2108 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
2109 Now that Owen explained the algorithm, I think I implemented it
2110 right for the cases where the destination pixbuf is not opaque.
2111 The test does seem to confirm it.
2113 2000-05-04 Darin Adler <darin@eazel.com>
2115 * gdk-pixbuf/.cvsignore:
2116 * gdk-pixbuf/Makefile.am:
2117 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
2118 (load_pixel), (simple_composite_test_one),
2119 (simple_composite_test_one_type), (simple_composite_test), (main):
2120 Added some tests of composite to highlight problems in the old
2121 implementation. These tests run without any user interaction.
2122 Just do "make check".
2124 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
2125 (composite_pixel), (composite_line): Fix composite to do a textbook
2126 "A over B" composite. This was clearly the intent, and it was easy
2127 to fix the code to do it. (Note to those that read my earlier tries
2128 at a patch; this version fixes typos that were present in all
2129 my patch attempts. I checked the final version by adding more tests.)
2131 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
2133 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
2134 offset y coordinate accordining to render_y0.
2136 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
2139 2000-04-22 James Henstridge <james@daa.com.au>
2141 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
2142 package to the devel package. The only file installed in bin is
2143 gdk-pixbuf-config, which belongs in -devel. This should allow having
2144 multiple versions of the main gdk-pixbuf package installed.
2146 2000-04-17 Karl Eichwalder <ke@suse.de>
2148 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
2149 Reported by Jens Finke.

2153 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
2154 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
2156 2000-04-13 James Henstridge <james@daa.com.au>
2158 * configure.in: when performing the configure check to see if
2159 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
2160 rather than the other way round. Also, call AC_MSG_RESULT in the
2161 even that dynamic modules were not supported.
2163 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
2165 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
2166 hook to the last unref operation.
2168 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
2169 function to set the last unref handler for a pixbuf.
2170 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
2171 It calls the pixbuf's destroy notification function and frees the
2172 GdkPixbuf structure itself.
2173 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
2176 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
2177 for the last unref handler and its user data.
2179 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
2180 g_new0() to allocate the pixbuf.
2182 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
2183 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
2184 was not specifying the `frame' argument.
2186 * gdk-pixbuf/gdk-pixbuf-animation.c
2187 (gdk_pixbuf_animation_get_width): Fixed docstring.
2188 (gdk_pixbuf_animation_get_height): Likewise.
2189 (gdk_pixbuf_animation_get_num_frames): Likewise.
2190 (gdk_pixbuf_animation_get_frames): Likewise.

2195 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
2197 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
2199 * doc/tmpl/refcounting.sgml: Updated with the information about
2200 the last unref handler.
2202 * doc/tmpl/*.sgml: Markup tweaks.
2204 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
2205 update the libtool version number for libgnomecanvaspixbuf as
2207 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
2208 as well, or the old ones won't work with the new stuff. Also,
2209 renamed the modules as follows.
2211 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
2212 modules are called "libpixbufloader-<format>.so" instead of
2213 "libpixbuf-<format>.so". They needed renaming so that the new
2214 loaders won't overwrite the old ones; even with the versioning
2215 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
2218 2000-04-12 Paolo Molaro <lupus@debian.org>
2220 * .cvsignore, src/.cvsignore: shut up cvs.
2222 2000-04-11 Federico Mena Quintero <federico@helixcode.com>

2265 (gdk_pixbuf_frame_get_action): New accessor.
2267 * gdk-pixbuf/gdk-pixbuf-render.c
2268 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
2269 mask rectangle for pixbufs without an alpha channel, set the
2270 *mask_return to NULL.
2272 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
2274 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
2276 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some

2301 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
2302 the version number of the libtool library to indicate that this
2303 definitely is not compatible with the old usage. I know you love

2721 * doc/tmpl/gdk-pixbuf-loader.sgml: much longer long description
2724 2000-01-05 Owen Taylor <otaylor@redhat.com>
2726 * gdk-pixbuf/pixops/pixops.c (pixops_process): Fix computation of
2729 * gdk-pixbuf/pixops/pixops.c: Fix double increments when

2732 2000-01-05 Mark Crichton <crichton@gimp.org>
2734 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_eat_header_write):

2794 * gdk-pixbuf/testpixbuf-scale: Test program for scaling
2797 2000-01-05 Jonathan Blandford <jrb@redhat.com>

2803 * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
2804 counting to animations. A web browser may want to share a single
2805 copy of an animated GIF if it appears multiple times in a web
2808 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
2809 animation functions here.
2810 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
2811 animation if the loader does not support multiframe loading and
2812 the single-frame load returned NULL. Check that the filename is
2813 not NULL. Updated inline documentation.
2814 (gdk_pixbuf_animation_ref): New function.
2815 (gdk_pixbuf_animation_unref): New function.
2816 Removed gdk_pixbuf_animation_destroy() in favor of reference
2819 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
2820 Prettified. Made ref_count assertion more paranoid. Check that
2821 the filename is not NULL.
2822 (gdk_pixbuf_get_module): Use guchar * and guint for buffer and
2824 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
2827 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
2828 with a reference count of 1.
2830 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
2831 gdk-pixbuf-animation.c.
2833 * doc/tmpl/animation.sgml: Populated. It is still missing a
2834 description of the overlay modes.
2836 * doc/gdk-pixbuf-sections.txt: Added the animation section. Moved
2837 the canvas item section to the end, as it will be moved later to
2840 * doc/gdk-pixbuf.sgml: Added the animation section.
2842 * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
2844 1999-12-26 Peter Teichman <pat@gnu.org>
2846 * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add
2847 $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker.
2848 This closes bug #4676.
2850 1999-12-23 Havoc Pennington <hp@pobox.com>
2852 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
2853 set to NULL here (specifically context->animation) was not being
2854 set to NULL. use g_new0() to alloc the struct.
2856 1999-12-20 Jonathan Blandford <jrb@redhat.com>
2858 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2859 correctly. Progressive loading needs some work, but that all
2860 needs doing from the gdk-pixbuf-loader end, not here.
2862 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2864 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2865 moved the file here. It seems natural to put this function here,
2866 as that's where the gdk_pixbuf_new_from_file function is, but it's
2867 still a little convoluted. The source files might be played with
2870 1999-12-14 Jonathan Blandford <jrb@redhat.com>
2872 * gdk-pixbuf/gdk-pixbuf-loader.c
2873 (gdk_pixbuf_loader_get_animation): Gets the animation from the
2876 1999-12-16 Federico Mena Quintero <federico@redhat.com>
2878 * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
2879 before using the GdkPixbuf rendering functions. Thanks to Joe
2880 Shaw <joe@off.net> for pointing this out.
2882 1999-12-13 Federico Mena Quintero <federico@redhat.com>
2884 * gdk-pixbuf/gnome-canvas-pixbuf.c
2885 (gnome_canvas_pixbuf_class_init): Renamed arguments to
2886 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
2887 consistency with the new canvas.
2888 (PixbufPrivate): Do the same renaming in the structure fields, for
2891 * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.
2893 1999-12-12 Federico Mena Quintero <federico@redhat.com>
2895 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
2896 conditional to see whether to link $(GNOME_LIBS) or not.
2898 1999-12-10 Jonathan Blandford <jrb@redhat.com>
2900 * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API.
2902 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
2903 make a warning go away.
2905 * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations.
2907 * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for

2916 Filled in body of function.
2917 (rgbconvert): Added GdkColormap parameter, and to all conversion
2919 (convert_real_slow): New function - should convert ANY visual/data
2920 format properly, but it aint fast. Used as a fallback when an
2921 optimised routine wont match.
2922 (rgbconvert): Do very specific tests on the data format to verify
2923 properly if the optimised version will do, otherwise use the
2924 fallback function for all other data formats.
2926 * gdk-pixbuf/Makefile.am: Re-enabled building of
2927 textpixbuf-drawable.
2929 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
2930 gdk_pixbuf_get_from_drawable().
2932 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
2934 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
2935 bug on two occasions.
2936 * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu
2937 function to the generic glib one.
2939 1999-12-08 Federico Mena Quintero <federico@redhat.com>
2941 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2942 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2943 checks and API definition. The body needs filling in and it needs
2944 to do the Right Thing(tm) for pixmaps plus the given colormap and
2945 windows and their own colormaps.
2947 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2948 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
2950 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
2952 * doc/tmpl/from-drawables.sgml: Populated.
2954 * doc/gdk-pixbuf.sgml: Added the from-drawables section.
2956 * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml.
2958 * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs
2961 1999-12-07 Federico Mena Quintero <federico@redhat.com>
2963 * doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about
2964 reference counting for GdkPixbuf structures.
2966 1999-12-07 Martin Baulig <martin@home-of-linux.org>
2968 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
2969 include $(GNOME_LIBS) here.
2971 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2973 Added missing "include <string.h>" to:
2974 * gdk-pixbuf/io-ras.c
2975 * gdk-pixbuf/io-bmp.c
2976 * gdk-pixbuf/io-ico.c
2978 1999-12-06 Federico Mena Quintero <federico@redhat.com>
2980 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
2983 1999-12-05 Federico Mena Quintero <federico@redhat.com>
2985 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2986 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2987 want, send me a patch to do the conditional stuff properly.
2988 Otherwise, please read the GNOME Programming Guidelines,
2989 especially the "CVS policies" section.
2991 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
2993 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
2995 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2997 * gdk-pixbuf/io-ico.c: Bug in palet-size
3000 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
3002 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
3003 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
3005 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
3007 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
3010 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
3011 (Windows Cursor files). These are identical to .ICO files,
3012 except for the signature and 2 extra fields for the hotspot.
3014 1999-12-03 Federico Mena Quintero <federico@redhat.com>
3016 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):
3017 Removed unused variable `item'.
3019 1999-12-03 Jonathan Blandford <jrb@redhat.com>
3021 * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
3022 explain this function better.
3024 1999-12-02 Federico Mena Quintero <federico@redhat.com>
3026 Source files moved from src/ to gdk-pixbuf/, to be consistent with
3029 * doc/Makefile.am: Modified for the new source directory.
3031 * configure.in: Likewise.
3033 * Makefile.am: Likewise.
3035 * autogen.sh: Likewise.
3037 * gdk-pixbuf/Makefile.am: Likewise.
3039 1999-12-02 Federico Mena Quintero <federico@redhat.com>

3099 * doc/tmpl/util.sgml: Documentation for the utility functions.
3101 1999-11-29 Owen Taylor <otaylor@redhat.com>
3103 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
3104 Keep the mask around until after we draw ... since
3105 the GC changes aren't flushed to the X server until we
3106 draw, destroying it before that may result in BadPixmap
3109 1999-11-30 Havoc Pennington <hp@pobox.com>
3111 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
3113 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
3115 1999-11-29 Federico Mena Quintero <federico@redhat.com>
3117 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
3118 should be made conditional, not blindly commented out.
3120 1999-11-29 Jonathan Blandford <jrb@redhat.com>
3122 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
3123 handle .ico files. Cool.
3125 1999-11-24 Jonathan Blandford <jrb@redhat.com>
3127 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
3130 1999-11-24 James Henstridge <james@daa.com.au>
3132 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
3133 top builddir rather than src. This still builds fine, and does not
3134 get gtk-doc into an infinite loop when trying to find all the source
3137 1999-11-23 Jonathan Blandford <jrb@redhat.com>
3139 * Removed #PRAGMA } from headers. Also, make compile if you don't
3140 have it installed, already.
3142 1999-11-22 Federico Mena Quintero <federico@redhat.com>
3144 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
3145 temporary buffer to the size of the interesction of the bounding
3146 box and the expose area, not the whole expose area. This speeds
3149 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
3150 not paint black on the mask, since we already cleared it in a
3151 single gdk_draw_rectangle() operation.
3153 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
3155 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
3157 1999-11-22 Havoc Pennington <hp@pobox.com>
3159 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
3160 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
3161 dependencies to LIBADD variables for loadable modules. Necessary
3162 for a Java dynamic loading thing to be able to figure it out.
3164 1999-11-22 Havoc Pennington <hp@pobox.com>
3166 * src/io-png.c (image_load_increment): Call the update_area
3167 callback depending on the number of rows loaded in this increment.
3169 * src/testpixbuf.c (main): slow down the progressive load demo
3171 1999-11-16 Havoc Pennington <hp@pobox.com>
3173 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
3175 1999-11-22 Jonathan Blandford <jrb@redhat.com>
3177 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
3178 for srcdir != buildir != . Beats me why; I can't figure it out.
3179 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
3181 1999-11-21 Jonathan Blandford <jrb@redhat.com>
3183 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
3184 <arjan@fenrus.demon.nl>
3186 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
3188 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
3189 Rework/reorder of the code. Each case has been separated into
3190 another function; its big but it should be quick.
3191 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
3192 opaque alpha information. Not all depths/formats have been
3193 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
3195 1999-11-17 Larry Ewing <lewing@gimp.org>
3197 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
3198 implement the bounds method correctly.
3199 (compute_viewport_affine): compute the affine need to fit the
3200 image within the viewport given by the args.
3201 (compute_render_affine): call compute_viewport_affine.
3203 1999-11-16 Havoc Pennington <hp@pobox.com>
3205 * src/gdk-pixbuf-drawable.h: Use includes from the current
3206 directory, not the system directory.
3208 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
3210 * src/testpixbuf-drawable.c: use includes from the current directory
3211 rather then from the system include directory as gdk-pixbuf
3212 includes are not yet installed when this is compiled.
3214 1999-11-13 Cody Russell <bratsche@dfw.net>
3215 * src/testpixbuf-drawable.c: Added a test program for drawable
3218 * src/Makefile.am: Build testpixbuf-drawable.
3220 1999-11-12 Cody Russell <bratsche@dfw.net>
3222 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.

3233 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3235 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
3238 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
3239 correctly. Patch from Arjan to do so.
3241 1999-11-10 Michael Fulbright <drmike@redhat.com>
3243 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
3246 * src/testpixbuf.c: Added final queued draw when done loading image.
3248 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3250 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
3253 1999-11-10 Federico Mena Quintero <federico@redhat.com>

3260 * src/io-png.c: Fixed some incompatible pointer initializations.
3262 * src/io-jpeg.c (image_load_increment): Remove unused variable.
3264 1999-11-09 Michael Fulbright <drmike@redhat.com>
3266 * src/testpixbuf.c: Fixed it to use timeout to read from file
3267 for progressive loading. Set TBF_KBPS=n, where n is the number of
3268 kilobytes/second to simulate in downloading. n has to be an integer.
3270 * src/io-jpeg.c: Slight cosmetic cleanup.
3272 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
3273 PBM loading has a similar problem and will address tomorrow.
3275 1999-11-09 Havoc Pennington <hp@pobox.com>
3277 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
3278 gdk-pixbuf-drawable stuff.
3280 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3282 * configure.in: Bumped version number to 0.4.
3284 1999-11-09 Michael Fulbright <drmike@redhat.com>
3286 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
3287 all types of PNM files now.
3289 * src/io-jpeg.c (image_load_increment): Figured out problem with
3290 loading Progressive JPEG's progressively (say that 10 times fast).
3291 Currently for Progressive JPEG's the entire image is loaded before
3292 it is displayed. libjpeg supports a fancier mechanism which I may
3295 With these changes all JPEG formats appear to load properly for me.
3297 1999-11-08 Jonathan Blandford <jrb@redhat.com>
3299 * src/io-ras.c (image_load_increment): Final patch from Arjan.
3300 Seems to do progressive loading.
3302 1999-11-08 Michael Fulbright <drmike@redhat.com>
3304 * src/io-pnm.c image_load (): Fixed so we do not create a separate
3305 pixel buffer when reading in image - we reuse the pixel data in
3306 the GdkPixbuf structure instead.
3308 1999-11-08 Michael Fulbright <drmike@redhat.com>
3310 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
3311 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
3312 I can't seem to find a utility to convert into this format.
3313 Next is to add progressive loading support for the PNM format.
3315 1999-11-07 Federico Mena Quintero <federico@redhat.com>
3317 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
3318 of the width, height, x, and y setting and pixels arguments.
3320 1999-11-05 Jonathan Blandford <jrb@redhat.com>
3322 * src/io-ras.c (image_load): third patch. Now it seems to load.
3324 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
3325 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
3327 * src/io-ras.c (image_load): new file from Arjan van de Ven
3328 <arjan@fenrus.demon.nl> to begin the ras loader.
3330 1999-11-05 Federico Mena Quintero <federico@redhat.com>
3332 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
3333 for internal use only.
3335 * doc/gdk-pixbuf.sgml: Likewise.
3337 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
3339 1999-11-05 Michael Fulbright <drmike@redhat.com>
3341 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
3342 files from a file. Next step is support for ASCII files, and
3343 then incremental loading.
3345 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3347 * Makefile.am: Added doc to SUBDIRS.
3349 1999-11-04 Michael Fulbright <drmike@redhat.com>
3351 * src/io-jpeg.c: Prettied up code slightly.
3352 * src/io-pnm.c: Start of pnm loader (from file and progressively).
3353 Doesn't do much yet (will finish tomorrow).
3354 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
3356 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3358 * doc/tmpl/rendering.sgml: Populated.
3360 * doc/Makefile.am: Added the template files.
3362 1999-11-04 Havoc Pennington <hp@pobox.com>
3364 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
3365 docs, explain what a dither offset is for.
3366 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3367 this function vs. gdk_pixbuf_render_to_drawable().
3369 1999-11-04 Havoc Pennington <hp@pobox.com>
3371 * configure.in: Use libart-config correctly; find gnome-config
3372 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3375 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3378 Patch untested in the inside-gnome-libs case, I need to commit
3379 then check out to the gnome-libs I'm using.
3381 1999-11-04 Michael Fulbright <drmike@redhat.com>
3383 * src/io-jpeg.c (image_begin_load): Add update_func callback.
3384 * src/io-jpeg.c (image_load_increment): Call updated callback when
3385 new graphic data decoded.
3387 1999-11-04 Jonathan Blandford <jrb@redhat.com>
3389 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_update): handle the
3391 * src/io-png.c (image_begin_load): add a update_func callback.
3392 * src/io-gif.c (image_begin_load): add a update_func callback.
3393 (gif_get_lzw): added the update_func ability

3397 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3399 * doc/tmpl/gdk-pixbuf.sgml: Populated.
3401 * doc/tmpl/refcounting.sgml: Populated.
3403 * doc/tmpl/file-loading.sgml: Populated.
3405 * src/gdk-pixbuf.c: Added documentation comments.
3407 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Added
3408 documentation comments.
3410 * doc/: Finished integrating the documentation framework.
3412 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3414 * configure.in: Removed libgif stuff now that we do not depend on it.
3415 Added the necessary cruft for gtk-doc.
3417 * src/Makefile.am: Unconditionally build the GIF loader.
3419 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3421 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
3422 Added a lot of comments to the file.
3424 * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
3427 1999-11-03 Michael Fulbright <drmike@redhat.com>
3429 * src/io-jpeg.c (image_load_increment): Further removal of
3430 bugginess in local buffering code. Handles grayscale jpegs
3433 * src/io-jpeg.c (image_load_stop): Was freeing local context
3434 for jpeg library before calling jpeg_decompres_finish ().
3436 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3438 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
3440 (gif_get_lzw): set the transparency to the right val.
3442 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3444 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
3445 Initiailize the x and y fields.
3446 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
3447 (PixbufPrivate): Renamed need_size_update to need_xform_update.
3448 (recompute_bounding_box): Do not use temporary values.
3450 1999-11-03 Jonathan Blandford <jrb@redhat.com>

3455 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): remove
3456 unneeded x,y,h,w vars.
3458 1999-11-03 Larry Ewing <lewing@gimp.org>
3460 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
3461 render_affine calculation for x,y offsets.
3462 (gnome_canvas_pixbuf_set_arg): add x,y args.
3463 (gnome_canvas_pixbuf_get_arg): add x,y args.
3464 (recompute_bounding_box): simply code using ArtDrect and the
3465 render_affine. Removed compute_xform_vectors as it was no longer
3468 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3470 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
3471 doofus. Return a distance, not a boolean, for opaque images.
3473 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
3474 rounding of bounding box coordinates.
3475 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
3476 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
3478 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3480 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
3482 1999-11-03 Michael Fulbright <drmike@redhat.com>
3484 * src/io-jpg.c (image_load_increment): Fixed code which moved
3485 buffer around as new data comes in to work properly. JPEG progressive
3486 loading should be working now except for grayscale JPEG's, which I
3487 will look into next.
3489 1999-11-03 <sopwith@redhat.com>
3490 * src/testpixbuf.c: A GtkFunction needs to return a value for
3491 deterministic behaviour. Also put dot printing back in.
3493 1999-11-03 <jrb@redhat.com>
3495 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
3498 1999-11-02 Cody Russell <bratsche@dfw.net>
3499 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
3500 if part of the requested image is offscreen, rather than clipping
3503 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3505 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
3506 for interlacing and progressive loading.
3508 1999-11-02 Cody Russell <bratsche@dfw.net>
3509 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
3510 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
3512 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3514 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
3515 It's a little slow though. )-:
3517 1999-11-02 Elliot Lee <sopwith@redhat.com>
3518 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the
3519 arguments to the write/load_increment operations const-correct.
3521 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3523 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
3524 Implemented the ::point() method. We do a simple containment test
3525 instead of a full distance calculation since the canvas is going
3526 to change to that scheme, anyways.
3528 1999-11-02 Elliot Lee <sopwith@redhat.com>
3530 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size
3531 of the chunks that are read from the input file.
3533 1999-11-02 Larry Ewing <lewing@gimp.org>
3535 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
3537 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
3540 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3542 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3543 affine computation code from ::draw() to here, since it is needed
3544 by ::point() as well.
3546 1999-11-02 Elliot Lee <sopwith@redhat.com>
3548 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3549 three functions, and eliminate duplication of code from write()
3550 and close(). Also fix bug where the 128-byte header was being
3553 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3554 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3555 bounding box computation.
3557 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3559 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3560 Drawing affines seem to work. Bounding box is fubared. ::point()
3561 is not implemented. This is a work in progress.
3563 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3566 * configure.in: Sigh. We need to link in libgnomeui for the
3567 canvas stuff. This mess will disappear when gdk-pixbuf gets
3568 folded into gnome-libs.
3570 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3572 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3573 the right size, at a minimum, even if the image is squished and
3575 (ReadImage): lets get the offset right. This will let transparent
3578 1999-10-29 Michael Fulbright <drmike@redhat.com>
3580 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3581 image width was not a multiple of 4 - always use the
3582 gdk_pixbuf rowstride to increment pointers!
3584 1999-10-29 Michael Fulbright <drmike@redhat.com>
3586 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3587 Currently does not handle either progressive jpeg files (jpeg
3588 files with multiple scans at different quality settings), but
3589 I plan on adding this support soon. These are fairly rare in
3590 my experience, so it shouldn't slow people down too much.
3591 Grayscale jpegs also don't work but that should be easy to fix.
3593 1999-10-29 Michael Fulbright <drmike@redhat.com>
3595 * src/testpixbuf.c: Added title to windows so you can identify
3596 progressive and file windows.
3598 1999-10-29 Michael Fulbright <drmike@redhat.com>
3600 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3601 load the image handler when we determine the image type.
3603 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3604 previously static function load_image_handler () to
3605 a public function gdk_pixbuf_load_module (). It is needed in
3606 gdk-pixbuf-loader.c to load image handler modules. This function
3607 is different from gdk_pixbuf_get_module (), which only returns
3608 a reference to the required handler, because it actually loads
3609 the handler into memory. Both actions should possibly be combined
3610 in a convenience function since one w/o the other doesn't seem to
3613 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3615 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
3618 1999-10-28 Federico Mena Quintero <federico@redhat.com>
3620 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3621 function to render a portion of a pixbuf to a drawable. Ignores
3622 alpha information and takes in a GC.
3623 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3624 portion of a pixbuf to a drawable. It automatically creates a GC
3625 and a clipping mask for alpha pixbufs.
3627 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3629 * src/gdk-pixbuf.h: turned convenience macros into convenience
3630 functions so some error checking could be added.
3632 * src/io-tiff.c (image_load_increment): started work on the tiff
3633 non-incremental loader.
3634 (image_begin_load): Finished the incremental loader.
3636 * src/io-gif.c (image_load_increment): started work on the gif
3639 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
3641 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3643 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3644 function to threshold a pixbuf's alpha channel into a bitmap.
3646 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3647 contemplate future extensions to ArtPixBuf's formats.
3649 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3651 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3652 macros to fetch the ArtPixBuf's fields.
3654 1999-10-27 Havoc Pennington <hp@pobox.com>
3656 * src/testpixbuf.c (main): Display the progressive load
3658 * src/io-png.c (setup_png_transformations): Break transformation
3659 code into separate function
3660 (png_info_callback): Use setup_png_transformations
3662 1999-10-27 Havoc Pennington <hp@pobox.com>
3664 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3665 properly whether the XPM module has already been loaded
3666 (gdk_pixbuf_new_from_file): Check properly if loader module
3667 was already loaded (was checking if load symbol was present
3668 in order to decide whether to re-load; should check module !=
3669 NULL, then load != NULL)
3670 (image_handler_load): Check in present working directory,
3671 makes it easier to debug for now
3672 (file_formats): This array initializer was seriously on crack,
3673 was assigning a function pointer to a GModule*
3675 * src/testpixbuf.c (main): Change type of pixbuf_loader to
3678 1999-10-27 Havoc Pennington <hp@pobox.com>

3686 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
3687 GdkPixbufLoader, not a GtkObject.
3688 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
3689 (gdk_pixbuf_loader_get_type): Documented.
3690 (gdk_pixbuf_loader_class_init): Initialize the parent class

3693 class destroy function.
3694 (gdk_pixbuf_loader_new): Documented.
3695 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3697 (gdk_pixbuf_loader_write): Use size_t for count.
3699 1999-10-27 Michael Fulbright <drmike@redhat.com>
3701 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3702 logic so we only try to close loader if it wasn't previously closed.
3704 1999-10-27 Michael Fulbright <drmike@redhat.com>
3706 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of
3707 pixbuf_loader properly initialized.
3709 * src/testpixbuf.c: Made sure we cleanup pixbuf_loader properly
3712 1999-10-26 Jonathan Blandford <jrb@redhat.com>
3714 * src/gdk-pixbuf-io.c (image_handler_load): load the vtable fully.
3716 * src/gdk-pixbuf-loader.c: Finished initial cut at the object.

3730 1999-10-25 Federico Mena Quintero <federico@redhat.com>
3732 * configure.in (CFLAGS): Patch from Uwe Koloska
3733 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3735 1999-10-22 Havoc Pennington <hp@pobox.com>
3737 * src/io-xpm.c (mem_buffer): Clean up stupid
3738 increment-inside-array-dereference thing
3740 * src/testpixbuf.c: Add XPM data tests.
3742 * src/io-xpm.c: Make the XPM data buffer const, fix const
3743 correctness throughout the code.
3745 1999-10-22 Havoc Pennington <hp@pobox.com>
3747 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

3757 module isn't loaded twice. Add g_module_symbol() to scan for XPM
3760 1999-10-22 Federico Mena Quintero <federico@redhat.com>
3762 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3763 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
3764 buffers; the rows can be read in directly into the main pixel
3767 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3769 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
3771 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3773 * configure.in: Bumped version number to 0.3.
3775 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
3776 version number for the library.
3778 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3780 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
3781 all memory management of the buffer is done by libart.
3783 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
3784 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
3786 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
3787 terms of the libart functions. Removed the old code.
3789 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
3790 symbols. Saving will not be implemented in GdkPixbuf.
3792 * src/io-gif.c: Removed the saving stub.
3793 (image_load): Fixed memory management to fail gracefully if we run
3794 out of memory while loading the image. Close the gif file when we
3795 are done. This still needs more error handling for the DGif
3798 * src/io-jpeg.c (image_load): Some robustness fixes.
3800 * src/io-png.c: Removed the saving stuff.
3801 (image_load): Some memory management fixes.
3803 * src/io-tiff.c (image_load): Ditto.
3805 * src/io-xpm.c (pixbuf_create_from_xpm): Ditto.
3807 1999-10-18 Havoc Pennington <hp@pobox.com>
3809 * subautogen.sh: New name for macros/autogen.sh
3811 * autogen.sh: use subautogen.sh
3813 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3815 * src/*: Reindented to use the GNOME Indentation. Renamed
3816 GdkPixBuf to GdkPixbuf, for consistency with the function names
3817 (and it is also easier to type) :-)
3819 1999-10-18 Havoc Pennington <hp@pobox.com>
3821 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
3823 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
3825 1999-10-18 Havoc Pennington <hp@pobox.com>
3827 * Makefile.am (SUBDIRS): Remove "macros"
3829 * configure.in: Don't use GNOME_INIT, handle case where we are
3830 inside gnome-libs. AM_PATH_GTK for the GIF test
3832 * src/Makefile.am: Change flags to work without libgnomeui,
3833 comment out testpixbuf for now
3835 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3837 * configure.in: Use $GTK_LIBS as the extra libs when checking for
3838 libgif/libungif, as they need the X libraries. Fixes bug #2472.
3840 1999-10-10 Cody Russell <bratsche@dfw.net>
3841 * src/gdk-pixbuf-drawable.c: core function now determines whether
3842 the requested geometry is on screen or not, and if some is not
3843 then the request is clamped to geometry that is on the screen.
3845 Changed 'pixbuf' to 'art_pixbuf' in core function.
3847 1999-10-08 Michael Fulbright <drmike@redhat.com>
3849 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.
3851 * src/testpifbuf: Changed test program to display cdrom from rgb data
3852 if no filename given to test program.
3854 1999-10-07 Cody Russell <bratsche@dfw.net>
3855 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
3856 them, but I wrote them).
3858 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
3861 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
3862 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.
3864 * src/gdk-pixbuf-drawable.c: Added #include "gdk-pixbuf-drawable.h"
3867 * src/gdk-pixbuf-drawable.[ch]: Changed functions to return
3868 GdkPixBuf* instead of ArtPixBuf*.
3870 1999-09-22 Michael Meeks <michael@nuclecu.unam.mx>
3872 * src/gdk-pixbuf.c (gdk_pixbuf_new): created.

3875 * src/gdk-pixbuf.h (struct _GdkPixBuf): Re-organise struct, + add
3876 GdkPixBufUnrefFunc + gdk_pixbuf_new.
3878 * src/io-jpeg.c (image_load): clean to use gdk_pixbuf_new.
3880 * src/io-xpm.c (_pixbuf_create_from_xpm): ditto.
3882 * src/io-tiff.c (image_load): ditto + fix leak
3884 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
3885 crashes this module ( add warning :-)
3887 * src/io-bmp.c (image_load): ditto.
3889 * src/io-gif.c (image_load): ditto.
3891 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
3893 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
3894 it doesn't crash scaling with alpha.
3896 1999-09-17 Federico Mena Quintero <federico@redhat.com>
3898 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
3900 * src/io-gif.c (image_load): Likewise.
3902 * src/io-jpeg.c (image_load): Likewise.
3904 * src/io-png.c (image_load): Likewise.

3908 * src/io-xpm.c (_pixbuf_create_from_xpm): Likewise.
3910 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_image): Added an assertion
3911 for the ref_count to be != 0.
3913 * src/gdk-pixbuf.c (gdk_pixbuf_ref): Be more paranoid with sanity
3915 (gdk_pixbuf_unref): Fix incorrect sanity check and comparison.
3917 1999-08-09 Federico Mena Quintero <federico@nuclecu.unam.mx>
3919 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
3920 to unallocated memory (row_ptr), and fixed its type as well. Take
3921 into account the ArtPixbuf's rowstride when assigning the row
3924 * src/gdk-pixbuf.c: Fixup includes.
3926 * src/gdk-pixbuf-io.c: Likewise.
3928 Sat Jul 31 19:19:47 CEST 1999
3930 * src/gdk-pixbuf-io.c:
3931 * src/io-png.c: Fixed two obvious C syntax bugs
3933 1999-07-29 Mark Crichton <crichton@gimp.org>
3935 * src/io-png.c (image_save): Added PNG saving function
3937 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
3938 image_save(GdkPixBuf *p, FILE *f, ...)
3941 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
3943 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3944 require extra libraries if we actually have those libraries.
3946 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3948 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
3949 * gdk_pixbufConf.sh.in: Added for gnome-config
3951 * configure.in: Modified to generate gdk_pixbufConf.sh
3953 1999-07-20 Mark Crichton <crichton@gimp.org>
3955 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3956 calculation needs to be done.
3958 1999-07-18 Larry Ewing <lewing@gimp.org>
3963 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3964 error cases but one or two in the common case. There are probably
3965 a few small ones left.
3967 1999-07-18 Mark Crichton <crichton@gimp.org>
3969 * configure.in: removed version.h.
3971 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3974 1999-07-17 Mark Crichton <crichton@gimp.org>
3976 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
3977 (gdk_pixbuf_rotate): Added pixbuf rotation code.
3978 (gdk_pixbuf_scale): Changed // comments to /* */
3980 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
3983 1999-07-16 Larry Ewing <lewing@gimp.org>
3985 * src/testpixbuf.c (expose_func): reverted the expose everything
3986 changes, I'm not sure why these went in.
3987 (config_func): bring this up to date with the new pixbuf_scale
3990 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3991 loading code so that poeple can diagnose problems better.
3993 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3994 no longer allocates a new pixbuf, which make things nicer for the
3995 rest of the code. Unfortunately there is still a problem with
3996 scaling rgba images.
3998 1999-07-16 Mark Crichton <crichton@gimp.org>
4000 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
4001 calls gdk_pixbuf_scale. However, something is not working.
4002 N.B.: current pixmap is now stored in user_data with a key of
4005 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
4006 Something is still borked, however.
4008 1999-07-15 Larry Ewing <lewing@gimp.org>
4010 * src/io-jpeg.c (image_load): add raph@gimp.org's fix to the jpeg
4013 * src/testpixbuf.c (main): fix up the file routines a little so
4014 that you can load multiple files given the file names
4016 1999-07-14 Larry Ewing <lewing@gimp.org>
4018 * src/testpixbuf.c (expose_func): added an almost proper expose
4019 handler for testpixbuf
4021 1999-07-13 Mark Crichton <crichton@gimp.org>
4023 * configure.in: Fixed GIF check. Replaced " with '
4024 * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale
4026 1999-07-13 Mark Crichton <crichton@gimp.org>
4028 * configure.in: I am a bonehead. Added gif-lib check.
