536 2002-07-06 Matthias Clasen <maclas@gmx.de>
538 * io-tiff.c (tiff_set_error): Handle global_error == NULL
540 (tiff_image_parse): Don't trust TIFFRGBAImageBegin to set
541 the "put" routine. (Fixes #87384)
542 (gdk_pixbuf__tiff_image_stop_load): Don't call TIFFClose too
545 2002-07-02 Matthias Clasen <maclas@gmx.de>
547 Miscellaneous bmp loader fixes (#85448, #86286, #86287):
549 * io-bmp.c (grow_buffer): New function to avoid crashes
550 on unchecked reallocs.
551 (DecodeHeader, DecodeColormap, decode_bitmasks,
552 DoCompressed): Use grow_buffer instead of g_realloc
553 throughout. Change signatures where necessary to pass the
555 (OneLine16): Fix loading of 16bpp BI_RGB bmps.
556 (DoCompressed): Rewritten to properly support BI_RLE4 and
559 Support for compressed ras images (#84994):
561 * io-ras.c (RAS2State): Error on unsupported ras variations.
562 (OneLine8): Fix colormap indexing.
563 (OneLine): Call updated_func with proper region.
564 (DoCompressed): New function, handles compressed ras data.
565 (gdk_pixbuf__ras_image_load_increment): Handle compressed ras
568 Better colorspace support for the jpeg loader (#61211):
570 * io-jpeg.c (convert_cmyk_to_rgb): New function.
571 (gdk_pixbuf__jpeg_image_load,
572 gdk_pixbuf__jpeg_image_load_increment): Allocate a pixbuf with
573 alpha for 4-channel jpegs and call convert_cmyk_to_rgb for these.
575 All of this needs to be merged to GNOME 1.4 gdk-pixbuf.
577 2002-06-28 Sven Neumann <sven@gimp.org>
579 * gdk-pixbuf-csource.c (print_blurb): converted a Tab to spaces.
581 Thu Jun 13 18:11:11 2002 Owen Taylor <otaylor@redhat.com>
583 * pixops/pixops.c: Fix problem where when no alpha was
584 involved, we scaled rather than composited, but then
585 went ahead and composited anyways. (#76958, Patch
586 from Matthias Clasen). Needs to be merged to GNOME
589 2002-06-13 Matthias Clasen <maclas@gmx.de>
591 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
592 incrementally display incrementally loaded progressive jpegs.
594 2002-06-07 Federico Mena Quintero <federico@ximian.com>
597 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
598 starting at a specific memory location. We do this instead of
599 GINT32_FROM_LE() as the latter is simply dereferences a cast,
600 which doesn't work on platforms with alignment requirements.
603 2002-06-01 Matthias Clasen <maclas@gmx.de>
605 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
606 with a C comment - those seem to be not uncommon, e.g. the Gimp
607 produces them. (#82706)
609 * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
611 (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.
613 2002-05-22 Tor Lillqvist <tml@iki.fi>
615 * gdk-pixbuf-io.c (get_libdir): Use GTK_BINARY_VERSION (and not
616 GTK_VERSION) in the path to the loaders on Win32, too.
618 * Makefile.am: Pass GTK_BINARY_VERSION.
620 2002-05-22 Federico Mena Quintero <federico@ximian.com>
622 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
623 account!!! Fixes #82515.
625 [This bug is not present in the GNOME 1.4 branch as its XPM loader
626 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
627 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
629 [IMPORTANT: The comment above is to make my life easier when
630 merging stuff across branches. If you make changes to gdk-pixbuf
631 in either branch, please include a comment in the ChangeLog that
632 indicates whether this should be merged into the other branch.
635 2002-05-18 Matthias Clasen <maclas@gmx.de>

650 2002-05-07 Michael Natterer <mitch@gimp.org>
652 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
653 conditionally like the dynamic ones so --without-lib<foo> is
654 honored when building with --disable-modules. (#66867)
656 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
658 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to
660 * test-loaders.c, test-images.h: remove
662 2002-04-24 Matthias Clasen <maclas@gmx.de>
664 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
665 restriction from the description of png tEXt parameters.
667 * io-png.c (png_text_to_pixbuf_option):
668 (gdk_pixbuf__png_image_save): If libpng supports it,
669 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
671 2002-04-11 Matthias Clasen <maclas@gmx.de>
673 More fixes for #77807:
675 * io-tga.c (get_contiguous_pixbuf): Helper function to create
676 a pixbuf with a contiguous pixel array while being careful about
679 * io-tga.c (fill_in_context, get_image_pseudocolor,
680 get_image_truecolor, get_image_grayscale): Use
681 get_contiguous_pixbuf instead of manually allocating image
684 * io-xpm.c (pixbuf_create_from_xpm):
685 * io-pnm.c (gdk_pixbuf__pnm_image_load):
686 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
687 instead of manually allocating image storage.
689 2002-04-09 Matthias Clasen <maclas@gmx.de>
691 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
692 priv->image_module->module_name instead of image_type which may
695 2002-04-06 Matthias Clasen <maclas@gmx.de>
697 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
698 gdk_pixbuf_new instead of manually allocating image storage. This
699 gives us a good rowstride and overflow checks. (#77807)
701 2002-04-05 Matthias Clasen <maclas@gmx.de>
703 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
704 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable

712 2002-03-29 Matthias Clasen <maclas@gmx.de>
714 * io-png.c (png_simple_error_callback): libpng error handlers must
715 not return to their callers, thus longjmp out. This prevents
716 annoying stderr output from the default error handler.
718 2002-03-27 Matthias Clasen <maclas@gmx.de>
720 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
722 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
723 end_info. Also call png_read_end to check proper ending of the png
724 file and catch text chunks after the image data.
726 2002-03-27 Matthias Clasen <maclas@gmx.de>
728 * io-png.c (gdk_pixbuf__png_image_load,
729 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
730 instead of system malloc.
732 2002-03-26 Matthias Clasen <maclas@gmx.de>
734 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
736 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
737 context->buf on error.
739 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
740 stop_load even for short images to prevent memleaks.
742 2002-03-25 Matthias Clasen <maclas@gmx.de>
744 * io-png.c (setup_png_transformations): Changed signature to
745 return success and set a GError parameter, adjusted all callers.
746 Also work around a possible FPE in libpng and always check that
747 the new info is sane.
749 2002-03-23 Matthias Clasen <maclas@gmx.de>
751 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
752 context->updated_func is NULL during a nonincremental load.
753 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
755 2002-03-18 Matthias Clasen <maclas@gmx.de>
757 * io-tga.c: Fix assumptions on rowstride by manually allocating a
758 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
759 Support grayscale + alpha (which can be written, but not read (!)
762 2002-03-15 Matthias Clasen <maclas@gmx.de>
764 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
766 2002-03-13 Matthias Clasen <maclas@gmx.de>
768 * test-images.h: Add valid_ras_test and invalid_bmp_1.
770 * test-loaders.c (main): Add random tests for ras and pnm and an
771 invalid bmp which was a crasher until my 2002-03-12 commit.
773 * io-pnm.c (gdk_pixbuf__pnm_image_load_increment): Don't unref the
776 * io-ras.c: Handle some errors.
778 2002-03-12 Sven Neumann <sven@gimp.org>
780 * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
781 calling memcpy(). Simpler and potentially faster. (#70332)
783 2002-03-12 Matthias Clasen <maclas@gmx.de>
785 * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
786 which could actually be reached by a proper error status return.
788 2002-03-05 Matthias Clasen <maclas@gmx.de>
790 * test-loaders.c, test-images.h: More random tests.
792 * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.

802 * gdk-pixbuf-io.c (_gdk_pixbuf_load_module): If we
803 can't load the module using the g_module_build_path()
804 filename, try loading it as a .la file.
806 * test-loaders.c: Look for modules in current directory
807 rather than .libs, so we find the right .la files.
809 * test-loaders.c: Back out some accidental commits.
811 Sat Mar 2 21:28:03 2002 Owen Taylor <otaylor@redhat.com>
813 * gdk-pixbuf.c (gdk_pixbuf_new): Bullet-proof against integer

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

1095 2001-11-03 Sebastian Wilhelmi <wilhelmi@ira.uka.de>
1097 * gdk-pixbuf-loader.c, gdk-pixbuf-scale.c: Documentation fixes.
1099 2001-10-29 Tor Lillqvist <tml@iki.fi>
1101 * Makefile.am: Use -no-undefined on Win32. Make
1102 libgdk_pixbuf_1_3_la_OBJECTS depend on
1103 gdk-pixbuf-marshal.c. Install import libraries.
1105 * gdk_pixbuf.def: Update.
1107 * gdk-pixbuf-io.c: (Win32) Use G_WIN32_DLLMAIN_FOR_DLL_NAME, saves
1108 the actual DLL name of libgdk_pixbuf.
1109 (get_libdir): Use it instead of guessing.
1111 * io-xbm.c (gdk_pixbuf__xbm_image_begin_load): Use
1112 g_file_open_tmp() insread of mkstemp().
1114 2001-10-18 Matthias Clasen <matthiasc@poet.de>
1116 * io-xbm.c (gdk_pixbuf__xbm_image_load_real): Don't dereference
1117 context when it may be NULL. (#62344)
1119 2001-10-16 Matthias Clasen <matthiasc@poet.de>
1121 * gdk-pixdata.c, gdk-pixdata.h: Documentation.
1123 * gdk-pixbuf-csource.1: Spelling fixes.
1125 Wed Oct 10 11:52:17 2001 Owen Taylor <otaylor@redhat.com>
1127 * gdk-pixdata.c gdk-pixbuf.h: Get rid of
1128 GDK_PIXBUF_ERROR_HEADER/PIXEL_CORRUPT and use CORRUPT_IMAGE.
1129 Get rid fo GD_PIXBUF_ERROR_UNKNOWN_FORMAT and use the
1130 existing UKNOWN_TYPE error. (#58308)
1132 * gdk-pixbuf.h, gdk-pixdata.c: Rename gdk_pixbuf_new_from_stream()
1133 back to gdk_pixbuf_new_from_inline(). Rework docs to try
1134 and be helpful for the common case. (#58308)
1136 2001-10-05 Sven Neumann <sven@gimp.org>
1138 * gdk-pixbuf/gdk-pixbuf-io.c
1139 * gdk-pixbuf/gdk-pixbuf-private.h
1140 * gdk-pixbuf/gdk-pixbuf.c
1141 * gdk-pixbuf/gdk-pixbuf.h
1142 * gdk-pixbuf/io-jpeg.c
1143 * gdk-pixbuf/io-png.c: changed GDK_PIXBUF_ERROR_BAD_OPTION_VALUE to
1144 GDK_PIXBUF_ERROR_BAD_OPTION to we can use it for bad keys too. Added
1145 new public API gdk_pixbuf_get_option() to retrieve key/value pairs
1146 set by an image loader. Added support for saving and reading PNG tEXt
1147 chunks in PNG images.
1149 Tue Oct 2 11:29:50 2001 Owen Taylor <otaylor@redhat.com>
1151 * gdk-pixdata.c (gdk_pixdata_to_csource): Fix indentation
1152 use a macro to make code a bit more readable.
1154 2001-10-02 Sven Neumann <sven@gimp.org>
1156 * gdk-pixdata.c: g_string_printfa => g_string_append_printf.
1158 Wed Sep 26 18:08:19 2001 Owen Taylor <otaylor@redhat.com>
1160 * Makefile.am (s-enum-types-h): Fix a typo in the include
1161 guards. (#61254, Skip Montaro)
1163 2001-09-21 Matthias Clasen <matthiasc@poet.de>
1165 * io-xpm.c (xpm_extract_color): Rewritten to handle
1166 xpm colormap entries more thoroughly. (#59939)
1168 2001-09-21 Hans Breuer <hans@breuer.org>
1170 * gdk-pixbuf.def : updated externals
1172 * makefile.msc : generate gdk-pixbuf-enum-types.[hc]
1174 Thu Sep 20 17:22:48 2001 Owen Taylor <otaylor@redhat.com>
1176 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
1177 works in some on-demand way, so the fseek
1178 gdk_pixbuf_new_from_file() doesn't work here since we are using
1179 the raw file descriptor. So, we call lseek() on the fileno(f)
1180 before using it. (#60840).
1182 2001-09-20 James Henstridge <james@daa.com.au>
1184 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
1185 so that flags types are registered as flags rather than enums (not
1186 that there are any flags here at the moment).
1188 Wed Sep 19 00:28:24 2001 Owen Taylor <otaylor@redhat.com>
1190 * Makefile.am (gdk_pixbuf_headers): Don't include
1191 gkd-pixbuf-features.h here since is in builddir
1192 and confuses autogen rules.
1194 * Makefile.am: Don't += variables before they have values,
1195 automake-1.5 doesn't like it.
1197 * Makefile.am: Fix srcdir != builddir for gdk-pixbuf-enum-types.c.
1199 * Makefile.am: The whitespace strikes back.
1201 2001-09-17 Matt Wilson <msw@redhat.com>
1203 * Makefile.am (libpixbufloader_xbm_la_LDFLAGS): removed duplicate
1204 LDFLAGS definition, use the -avoid-version one.
1205 (libpixbufloader_tga_la_LDFLAGS): likewise
1207 Mon Sep 17 11:49:02 2001 Owen Taylor <otaylor@redhat.com>
1209 * pixops/*: Mirror GdkInterpType to PixopsInterpType
1210 to avoid including gdk-pixbuf headers.
1212 2001-09-16 James Henstridge <james@daa.com.au>
1214 * .cvsignore: add generated files to ignore list.
1216 * gdk-pixbuf.h: include gdk-pixbuf-enum-types.h
1218 * Makefile.am: add rules to build gdk-pixbuf-enum-types.[ch]
1220 Fri Sep 14 23:22:12 2001 Matthias Clasen <matthiasc@poet.de>
1222 * io-pnm.c (pnm_read_header): Use GDK_PIXBUF_ERROR_CORRUPT_IMAGE,
1223 not GDK_PIXBUF_ERROR_HEADER_CORRUPT. (#58308)
1225 Fri Sep 14 22:53:45 2001 Matthias Clasen <matthiasc@poet.de>
1227 * io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load): Handle
1228 out-of-memory situation better.
1230 * io-pnm.c: Robustness fixes for pnm loader
1232 * io-gif.c: Make gif loader survive TEST_RANDOMLY_MODIFY
1234 * io-xpm.c (parse_color): detect very long color strings
1236 All of the above from Matthias Clasen <matthiasc@poet.de>,
1237 the remaining from Soeren Sandmann <sandmann@daimi.au.dk>.
1239 * test-images.h: add tests:
1240 - four valid ppm's, eight invalid (matthiasc@poet.de)
1241 - one invalid xpm (matthiasc@poet.de)
1242 - one valid tga, one invalid (sandmann@daimi.au.dk)
1243 - one invalid tiff (sandmann@daimi.au.dk
1245 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
1247 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
1248 fail - detect it when it happens
1250 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
1253 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
1256 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
1258 * Makefile.am: don't used BUILT_SOURCES to build marshal
1259 files, as in conjunction with stamp files, this can
1260 lead to endless rebuilding loops.
1262 Tue Sep 4 00:22:07 2001 Owen Taylor <otaylor@redhat.com>
1264 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1
1266 Tue Sep 4 03:09:52 2001 Tim Janik <timj@gtk.org>
1268 * gdk-pixbuf-csource.1: new file, manual page for
1269 the publically installed gdk-pixbuf-csource utility.
1271 Thu Aug 30 08:30:03 2001 Matthias Clasen <matthiasc@poet.de>
1273 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Propagate
1274 errors from gdk_pixbuf_loader_load_module.
1276 Thu Aug 30 08:27:37 2001 Matthias Clasen <matthiasc@poet.de>
1278 * io-png.c (png_row_callback): Check that row_num is valid.
1280 Tue Aug 28 21:05:26 2001 Matthias Clasen <matthiasc@poet.de>
1282 * io-bmp.c (OneLine): Emit area_updated signal with proper
1283 area information. (#52002)
1285 Tue Aug 28 20:03:43 2001 Matthias Clasen <matthiasc@poet.de>
1287 * test-loaders.c (test_loader): Catch errors at close time.
1288 * test-loaders.c (main): Remove C++ comments.
1290 2001-08-21 Matthias Clasen <matthiasc@poet.de>
1292 * Makefile.am, gdk-pixbuf-io.c, pixbufloader_tga.def,
1293 io-tga.c: Add tga loader, patch by Nicola Girardi. (#56067)
1295 2001-08-20 Matthias Clasen <matthiasc@poet.de>
1297 * test-images.h, test-loaders.c: Add ico and wbmp tests.
1298 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): Fail with a suitable
1299 error if buffer allocation fails.
1300 * io-ico.c: Make .ICO loader more robust.
1301 All of these are due to sandmann@daimi.au.dk (#50187)
1303 2001-08-19 Sven Neumann <sven@gimp.org>
1305 * pixops/pixops.c: applied some simple but effective optimizations
1306 to pixops_composite_nearest() and pixops_composite_color_nearest().
1308 2001-08-07 Sven Neumann <sven@gimp.org>
1310 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
1311 function, so that's what I did.
1313 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
1315 * gdk-pixdata.c: Fix a typo.
1317 2001-07-30 Hans Breuer <hans@breuer.org>
1319 * pixops/makefile.msc : new file
1320 * makefile.msc : use it to complete the build
1322 2001-07-20 Hans Breuer <hans@breuer.org>
1324 * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
1325 pointer increment out of the macro, because at least one
1326 compiler (msvc 5.0) gets confused otherwise (applies the
1329 * gdk_pixbuf.def : updated exports
1331 * makefile.msc : reflect gdk-pixbuf-csource changes
1333 2001-07-17 Darin Adler <darin@bentspoon.com>
1335 * gdk-pixbuf-csource.c: Add missing <stdlib.h> include.
1336 * io-png.c: (setup_png_transformations): Add ifdef so we compile
1337 without warnings with G_DISABLE_CHECKS on.
1338 * io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
1340 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
1341 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
1342 unused locals and add an initial value to quiet the compiler's
1343 unintialized variable warning.
1344 * pixops/pixops.c: Put an ifdef around some dead code.
1346 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
1348 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
1349 over to the new include flags AC_SUBST(). (Problem
1350 pointed out by Mikael Hermansson.)
1352 2001-06-29 Havoc Pennington <hp@redhat.com>
1354 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): fix for
1357 Thu Jun 28 21:54:19 2001 Owen Taylor <otaylor@redhat.com>
1359 * make-inline-pixbuf.c test-gdk-pixbuf.c test-loaders.c
1360 gdk-pixbuf-csource.c: Fix args to g_type_init ().
1362 2001-06-28 Havoc Pennington <hp@pobox.com>
1364 * gdk-pixdata.c: <string.h>
1366 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
1367 also leaking memory here from g_strdup_printf?)
1369 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
1371 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
1373 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
1374 instead from gdk_pixbuf_new_from_inline().
1376 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
1377 installed API for applications that need to serialize/deserialize
1378 on their own (gimp, BEAST).
1380 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
1381 program that can dump images in CSource format and Pixbuf
1382 stream format. supports RLE encoding, MACRO formatting etc...
1385 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
1387 * Makefile.am: Actually update timestamps, so rules don't
1390 2001-06-11 Havoc Pennington <hp@redhat.com>
1392 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
1393 already includes top_builddir
1395 2001-06-08 Havoc Pennington <hp@redhat.com>
1397 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
1398 bogus g_return_if_fail
1400 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
1401 likely timeout resolution, set it to an arbitrarily-chosen short
1403 Fixes bug #55953 from warmenhoven@yahoo.com
1405 2001-06-07 Havoc Pennington <hp@redhat.com>
1407 * Makefile.am: use Owen's new way of doing stampfiles/generated
1410 2001-06-07 Havoc Pennington <hp@redhat.com>

1414 2001-06-05 Havoc Pennington <hp@redhat.com>
1416 * test-loaders.c (main): use putenv not setenv, reported by
1419 2001-05-08 Havoc Pennington <hp@redhat.com>
1421 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1422 and fix behavior to still subst color if the original image
1425 2001-06-04 Havoc Pennington <hp@redhat.com>
1427 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1430 2001-06-01 Havoc Pennington <hp@redhat.com>
1432 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1433 Makes things a bit more robust, and adds test-loaders.c
1434 which is good for finding further robustness bugs to fix.
1436 * io-tiff.c: Try to work around libtiff suckiness a bit;
1437 put a giant thread lock on the whole loader,
1438 paranoically check both whether error handlers were called and
1439 also whether functions return false. Handle case where width or
1440 height is 0. Various cleanups.
1442 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1444 (png_error_callback): apparently libpng expects you to longjmp out
1447 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1448 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1450 (gif_get_lzw): check for out-of-memory
1451 (gif_prepare_lzw): catch/report an error
1452 (new_context): use try_malloc, since GifContext is nearly 70K
1453 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1454 so we don't crash later.
1456 * Makefile.am: Add test-loaders
1458 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1461 2001-05-29 Darin Adler <darin@eazel.com>
1463 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1465 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1467 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1468 fix up bmp decoder to:
1469 - adds 16 bpp bmp support (bug #53884)
1470 - adds OS/2 1.x format bmp support (bug #54964)
1471 - adds 4 bpp RLE compressed bmp support
1472 - adds 1 bpp colormap support
1473 - fixes negative height (top down) bmp support
1475 2001-05-25 Hans Breuer <hans@breuer.org>
1477 * gdk_pixbuf.def : reflect Havoc's recent api change
1479 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1481 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1482 excess $(GLIB_LIBS).
1484 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1486 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1488 2001-05-04 Havoc Pennington <hp@redhat.com>
1490 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1491 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1494 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1495 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1496 confusion of using "src" instead of "p".
1497 (pixops_composite_color_nearest): Use a more accurate (and
1498 correct, to begin with) compositing method. This cures checks
1499 showing through on images with no alpha.
1501 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1504 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1506 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1507 area_updated signal to use signed ints. Removed animation-related
1510 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1513 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1514 all the pesky details. Remove old frame-based API. Make
1515 GdkPixbufAnimation an abstract base class, derived by the loaders.
1517 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1519 * Makefile.am (LDADDS): Add $(MATH_LIB).
1521 2001-04-18 Havoc Pennington <hp@redhat.com>
1523 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1526 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1528 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1529 so we don't try to get <gtk/gtkobject.h> from standard search
1532 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1533 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1534 take gdk-pixbuf-marshal.h out of _la sources.
1536 2001-03-19 Tor Lillqvist <tml@iki.fi>
1538 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1540 * gdk_pixbuf.def: Update.
1542 * pixbufloader_*.def: Just export the fill_vtable functions now.
1544 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1546 * make-inline-pixbuf.c (main): Added logic to remove output when
1549 2001-03-14 Havoc Pennington <hp@redhat.com>
1551 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1552 from gdk-pixbuf-marshal.h, fixes parallel makes.
1554 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1556 * test-gdk-pixbuf.c: fixed includes.
1558 2001-02-18 Havoc Pennington <hp@pobox.com>
1560 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1561 (gdk_pixbuf_get_named_module): prepend underscore
1562 (gdk_pixbuf_get_module): prepend underscore
1564 2001-02-19 Havoc Pennington <hp@redhat.com>
1566 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1568 2001-02-17 Havoc Pennington <hp@pobox.com>
1570 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1572 2001-02-07 Alexander Larsson <alexl@redhat.com>
1574 * io-xpm.c (free_buffer):
1575 Use g_free, since the buffer is allocated with g_try_alloc().
1577 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1579 * gdk-pixbuf-data.c: Fixes a minor typo.
1581 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1583 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1584 we finally need the gobject->gruntime rename.
1586 * *.c: scratched calls to g_type_init(), there's simply no point in
1587 doing that, use gtk_init().
1589 2001-02-01 Havoc Pennington <hp@pobox.com>
1591 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1592 in struct to "priv" for C++
1594 2001-01-31 Havoc Pennington <hp@pobox.com>
1596 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1598 2001-01-26 Havoc Pennington <hp@redhat.com>
1600 * gdk-pixbuf-io.c (mname): fix included modules case.
1602 2001-01-22 Havoc Pennington <hp@redhat.com>
1604 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1605 from gdk_pixbuf_load_module
1607 2001-01-22 Havoc Pennington <hp@redhat.com>
1609 * Makefile.am: Add built marshaller files to support
1610 GdkPixbufLoader signals
1612 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1613 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1614 module location, rather than acting as a fallback, because we are
1615 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1617 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1619 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1620 from gtk, and add error to close(), because stop_load may do
1621 parsing of the image.
1623 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1625 * io-*.c: make individual operations static, and add fill_vtable
1626 functions which are exported. Fix the collection of type warnings
1627 that surfaced, including a number of functions that didn't
1628 properly take a GError and some that weren't
1629 const-correct. Involved adding error handling for a few loaders.
1631 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1633 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1634 a function that fills in the GdkPixbufModule vtable, instead of
1635 looking up all the image functions individually; this means we
1636 can get type safety within modules for the loader functions.
1637 Also it means you don't have to keep the statically compiled and
1638 GModule versions in sync.
1640 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1642 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1644 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1646 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1649 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1651 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1654 2001-01-20 John Harper <jsh@eazel.com>
1656 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1657 collision between Xlib's RdBitF.c and io-tiff.c
1659 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1662 [ merged from stable gdk-pixbuf module. Untested, but it
1663 compiles, and works fine in the stable module ]
1665 2001-01-18 Tor Lillqvist <tml@iki.fi>
1667 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1668 g_win32_get_package_installation_subdirectory() function. No need
1669 to include windows.h.
1670 (gtk_win32_get_installation_directory): Remove this then.
1672 2001-01-01 Havoc Pennington <hp@redhat.com>
1674 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
1675 @LIBTOOL_EXPORT_OPTIONS@
1677 2000-12-30 Tor Lillqvist <tml@iki.fi>
1679 * gdk_pixbuf.def: Update.
1681 2000-12-16 Havoc Pennington <hp@pobox.com>
1683 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1684 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1685 (gdk_pixbuf_frame_copy): new function
1686 (gdk_pixbuf_frame_free): new function
1687 (gdk_pixbuf_frame_get_type): new function
1688 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
1690 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
1692 * Makefile.am: Add -avoid-version for all modules.
1694 2000-11-13 Havoc Pennington <hp@redhat.com>
1696 * io-png.c (png_simple_error_callback): fix error message to not
1697 say "save" since it's used for loading
1699 2000-11-11 Hans Breuer <Hans@Breuer.Org>
1701 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1702 contained image handlers (!USE_G_MODULE). Files to save should
1703 be opened in binary mode, fopen(s, "wb").
1705 * io-xpm.c : added HAVE_UNISTD_H condition
1707 2000-11-11 Tor Lillqvist <tml@iki.fi>
1709 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1711 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1712 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1713 mktemp() and open()).
1715 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1717 2000-11-01 Havoc Pennington <hp@pobox.com>
1719 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1720 a pixbuf pointing to a subregion of another pixbuf.
1722 2000-10-16 Tor Lillqvist <tml@iki.fi>
1724 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1726 2000-10-16 Havoc Pennington <hp@redhat.com>
1728 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1729 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1730 add error reporting here also
1732 * make-inline-pixbuf.c (main): use GError
1734 * io-xpm.c: include unistd.h
1736 * gdk-pixbuf-util.c: include string.h
1738 * io-*.c: add error reporting
1740 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
1743 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
1745 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1748 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1749 a G_FILE_ERROR if we fail to write or close the file.
1751 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1752 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1753 the GError naming rules. Add GError** to load functions.
1755 2000-10-06 Havoc Pennington <hp@redhat.com>
1757 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1759 2000-10-06 Havoc Pennington <hp@redhat.com>

1787 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
1789 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
1790 last nights code was still "broken". Should now properly handle
1791 all error conditions gracefully.
1793 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
1795 * gdk-pixbuf/io-pnm.c: Rewrote.
1797 2000-09-09 Federico Mena Quintero <federico@helixcode.com>
1799 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
1800 the correct dest offset.
1802 2000-08-25 Federico Mena Quintero <federico@helixcode.com>
1804 * gdk-pixbuf/io-xpm.c: #include <unistd.h>
1806 2000-08-05 Larry Ewing <lewing@helixcode.com>
1808 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.

1812 2000-07-26 Michael Meeks <michael@helixcode.com>
1814 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
1817 2000-07-21 Larry Ewing <lewing@helixcode.com>
1819 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
1820 xpm at least supports the progressive interface like the one in
1821 io-tiff.c. This should be reimplemented as an actual progressive
1824 2000-07-19 Jonathan Blandford <jrb@redhat.com>
1826 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
1827 make it look better.
1828 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
1829 meeks to handle errors better.
1831 2000-10-07 Tor Lillqvist <tml@iki.fi>
1834 * pixbufloader_jpeg.def
1835 * pixbufloader_png.def: Add new entry points.
1837 * makefile.mingw.in: Use libintl.
1839 2000-10-06 Havoc Pennington <hp@redhat.com>
1841 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
1842 consistent with gdk_pixbuf_loader_new_with_type().
1843 Return runtime error if a module is missing.
1845 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
1847 2000-10-05 Havoc Pennington <hp@redhat.com>
1849 Pixbuf saving, patch from David Welton.
1851 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
1852 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
1854 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf
1856 * io-png.c (gdk_pixbuf__png_image_save): PNG save routine.
1858 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): JPEG save routine.
1860 * gdk-pixbuf-io.c (gdk_pixbuf_save):
1861 (gdk_pixbuf_savev): Implement pixbuf saving routines
1863 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
1866 * gdk-pixbuf.h: Add public save routines; add pixbuf error
1869 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
1871 2000-10-05 Dan Winship <danw@helixcode.com>
1873 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
1874 all three of these files are the JPEG image loader. (From
1877 2000-10-03 Tor Lillqvist <tml@iki.fi>
1879 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
1880 gdk-pixbuf's version number in the rule for makefile.mingw itself.
1882 * gdk_pixbuf.def: Add new entry points.
1884 2000-09-26 Havoc Pennington <hp@redhat.com>
1886 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
1887 function here, instead of putting it in a private GTK+ file.
1889 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
1890 enum here for the known formats of inlined pixbufs.
1891 Also, #define our file magic here.
1893 2000-06-23 Havoc Pennington <hp@redhat.com>
1895 * make-inline-pixbuf.c: Small program that creates C variable
1896 declarations of inline pixbuf data. This can be read
1897 by gdk_pixbuf_new_from_inline.
1899 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
1900 inline pixbuf data and create a pixbuf from it.
1902 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1904 2000-09-07 Tor Lillqvist <tml@iki.fi>
1906 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1909 2000-08-12 Tor Lillqvist <tml@iki.fi>
1911 * gdk_pixbuf.def: Add missing entry point.
1913 2000-08-10 Havoc Pennington <hp@redhat.com>
1915 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1916 (s/pixbuf_/pixbufloader_)
1918 2000-08-02 Tor Lillqvist <tml@iki.fi>
1924 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1926 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1927 one. Fix names of DLLs to have '-' instead of '_'.
1929 2000-07-31 Elliot Lee <sopwith@redhat.com>
1930 * io-wbmp.c: Some bug fixes - now tested to work.
1932 2000-07-27 Elliot Lee <sopwith@redhat.com>
1934 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1935 gdk_pixbuf_get_named_module() function to facilitate above change
1936 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1937 Implement loader for WBMP format.
1938 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1940 2000-07-23 Tor Lillqvist <tml@iki.fi>
1945 * pixops/makefile.mingw.in
1946 * pixbuf_*.def: New files.
1949 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1951 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1952 New function, to get the GTK+ installation directory from
1953 the Windows Registry, where the installation program
1954 for whatever software includes GTK+ has stored it.
1956 Used to avoid having hardcoding the directory where to look for
1957 loaders. This function is needed by gtk, too, so it should
1958 really be just in one place. Maybe a small static library
1959 one level up from here?
1961 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1962 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1963 Open file in binary mode. This *is* standard C. (No-op on Unix,
1966 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1968 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1969 mktemp() and open().
1970 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1972 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1973 pseudo-op. Conditionalise on __MINGW32__, but probably
1974 should conditionalise on Gas version instead? Or could we
1975 do without .type on all systems?
1977 * pixops/timescale.c: Use g_get_current_time()
1978 instead of gettimeofday().
1980 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1982 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1984 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1986 * gdk-pixbuf.c: Add <string.h> include.
1988 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1990 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1991 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1992 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1993 use g_object_new() instead of g_type_create_instance() which
1994 is a private function for fundamental type implementations.
1996 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1998 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1999 soname scheme for gdk-pixbuf.
2001 2000-06-21 Havoc Pennington <hp@pobox.com>
2003 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
2004 (i.e. derivation is not allowed, and there are no virtual methods
2006 (gdk_pixbuf_preinit): Call g_type_init() here.
2007 (gdk_pixbuf_init): Add a user-friendly init function, for users
2008 of standalone gdk-pixbuf
2010 * gdk-pixbuf-animation.c: Convert to GObject, in the same
2011 way GdkPixbufAnimation was done.
2013 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
2014 gdk_pixbuf_finalize() from API, since these are broken and don't
2015 make sense with new GObject stuff.
2017 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
2019 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
2020 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
2023 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
2025 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
2026 so I needed something to warm my thighs. Running plain infinite
2027 loops on your laptop to make it hot is not very much fun. A demo
2028 of the gdk-pixbuf scaling functions is way better, and looks
2031 * configure.in (AC_OUTPUT): Added the demo Makefile.
2033 * Makefile.am (SUBDIRS): Added the demo directory.
2035 2000-06-09 Larry Ewing <lewing@helixcode.com>
2037 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
2038 setjmp for the png error handler. It seems setting the error
2039 handling functions does not avoid the jump, and so not calling
2040 setjmp was causing the incremental loader to jump into lala land.
2041 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
2042 not sure this one is actually required but the docs say it must be
2043 set for every call to a png_* function.
2044 Also changed the comment to reflect the fact that setting the
2045 error handlers does _not_ avoid the longjmp.
2047 2000-06-06 Larry Ewing <lewing@helixcode.com>
2049 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
2050 take frame offest into account when trying to calculate the
2051 animation bbox. Also set the width to the width not the height.
2052 (gdk_pixbuf_loader_animation_done): cycle over the frames to
2053 calculate bbox because now we finally have all the offset
2054 information for each frame.
2056 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
2058 * configure.in: add some gtk parameters to the
2059 GDK_PIXBUF_LIBĂƒĂ¯Â¿Â½Â²S and GDK_PIXBUG_INCLUDEDIR vars. One more
2060 fight in my crusade for strange prefix compile...
2062 2000-05-30 Not Zed <NotZed@HelixCode.com>
2064 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
2065 Initialise the error handler exit routine to our own. Note this
2066 means that every function that accesses the jpeg lib on this
2067 object MUST do a setjmp.
2068 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
2069 lib for handling fatal error.
2070 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
2071 your applications dont quit if there's a jpeg error!
2073 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
2075 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
2076 from Frank de Lange <frank@unternet.org>.
2078 2000-05-09 Darin Adler <darin@eazel.com>
2080 * gdk-pixbuf/test-gdk-pixbuf.c:
2081 Fixed includes to get rid of accidental GNOME dependency.
2083 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
2084 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
2086 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
2088 * configure.in: Bumped version number to 0.8.0.
2090 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
2091 file was not being distributed.
2093 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
2095 2000-05-09 Darin Adler <darin@eazel.com>
2097 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
2098 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
2099 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
2100 formats to 32-bit formats to re-use the high bits of the color values
2101 so that white maps to full white.
2103 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
2105 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
2106 detailed information about the structure and algorithms
2107 of pixops so people can fix it instead of breaking it.
2109 2000-05-04 Darin Adler <darin@eazel.com>
2111 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
2112 (composite_pixel), (composite_line):
2113 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
2114 Now that Owen explained the algorithm, I think I implemented it
2115 right for the cases where the destination pixbuf is not opaque.
2116 The test does seem to confirm it.
2118 2000-05-04 Darin Adler <darin@eazel.com>
2120 * gdk-pixbuf/.cvsignore:
2121 * gdk-pixbuf/Makefile.am:
2122 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
2123 (load_pixel), (simple_composite_test_one),
2124 (simple_composite_test_one_type), (simple_composite_test), (main):
2125 Added some tests of composite to highlight problems in the old
2126 implementation. These tests run without any user interaction.
2127 Just do "make check".
2129 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
2130 (composite_pixel), (composite_line): Fix composite to do a textbook
2131 "A over B" composite. This was clearly the intent, and it was easy
2132 to fix the code to do it. (Note to those that read my earlier tries
2133 at a patch; this version fixes typos that were present in all
2134 my patch attempts. I checked the final version by adding more tests.)
2136 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
2138 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
2139 offset y coordinate accordining to render_y0.
2141 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
2144 2000-04-22 James Henstridge <james@daa.com.au>
2146 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
2147 package to the devel package. The only file installed in bin is
2148 gdk-pixbuf-config, which belongs in -devel. This should allow having
2149 multiple versions of the main gdk-pixbuf package installed.
2151 2000-04-17 Karl Eichwalder <ke@suse.de>
2153 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
2154 Reported by Jens Finke.
2156 2000-04-14 Tomasz KĂƒĂ¯Â¿Â½Â³opczko <kloczek@pld.org.pl>
2158 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
2159 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
2161 2000-04-13 James Henstridge <james@daa.com.au>
2163 * configure.in: when performing the configure check to see if
2164 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
2165 rather than the other way round. Also, call AC_MSG_RESULT in the
2166 even that dynamic modules were not supported.
2168 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
2170 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
2171 hook to the last unref operation.
2173 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
2174 function to set the last unref handler for a pixbuf.
2175 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
2176 It calls the pixbuf's destroy notification function and frees the
2177 GdkPixbuf structure itself.
2178 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
2181 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
2182 for the last unref handler and its user data.
2184 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
2185 g_new0() to allocate the pixbuf.
2187 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
2188 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
2189 was not specifying the `frame' argument.
2191 * gdk-pixbuf/gdk-pixbuf-animation.c
2192 (gdk_pixbuf_animation_get_width): Fixed docstring.
2193 (gdk_pixbuf_animation_get_height): Likewise.

2202 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
2204 * doc/tmpl/refcounting.sgml: Updated with the information about
2205 the last unref handler.
2207 * doc/tmpl/*.sgml: Markup tweaks.
2209 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
2210 update the libtool version number for libgnomecanvaspixbuf as
2212 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
2213 as well, or the old ones won't work with the new stuff. Also,
2214 renamed the modules as follows.
2216 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
2217 modules are called "libpixbufloader-<format>.so" instead of
2218 "libpixbuf-<format>.so". They needed renaming so that the new
2219 loaders won't overwrite the old ones; even with the versioning
2220 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
2223 2000-04-12 Paolo Molaro <lupus@debian.org>
2225 * .cvsignore, src/.cvsignore: shut up cvs.
2227 2000-04-11 Federico Mena Quintero <federico@helixcode.com>

2272 * gdk-pixbuf/gdk-pixbuf-render.c
2273 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
2274 mask rectangle for pixbufs without an alpha channel, set the
2275 *mask_return to NULL.
2277 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
2279 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
2281 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some

2306 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
2307 the version number of the libtool library to indicate that this
2308 definitely is not compatible with the old usage. I know you love

2661 * gdk-pixbuf/gdk-pixbuf-render.c
2662 (gdk_pixbuf_render_pixmap_and_mask): Renamed from
2663 gdk_pixbuf_render_pixmap(). Do not create the mask if it is not
2664 needed, and do not use a clipping mask when rendering the pixmap.
2665 Tweaked documentation a little.

2676 checks more stringent. Removed "gint" abominations. Made
2677 documentation consistent with the rest of the functions.

2737 2000-01-05 Mark Crichton <crichton@gimp.org>
2739 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_eat_header_write):

2799 * gdk-pixbuf/testpixbuf-scale: Test program for scaling
2802 2000-01-05 Jonathan Blandford <jrb@redhat.com>

2808 * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
2809 counting to animations. A web browser may want to share a single
2810 copy of an animated GIF if it appears multiple times in a web
2813 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
2814 animation functions here.
2815 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
2816 animation if the loader does not support multiframe loading and
2817 the single-frame load returned NULL. Check that the filename is
2818 not NULL. Updated inline documentation.
2819 (gdk_pixbuf_animation_ref): New function.
2820 (gdk_pixbuf_animation_unref): New function.
2821 Removed gdk_pixbuf_animation_destroy() in favor of reference
2824 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
2825 Prettified. Made ref_count assertion more paranoid. Check that
2826 the filename is not NULL.
2827 (gdk_pixbuf_get_module): Use guchar * and guint for buffer and
2829 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
2832 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
2833 with a reference count of 1.
2835 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
2836 gdk-pixbuf-animation.c.
2838 * doc/tmpl/animation.sgml: Populated. It is still missing a
2839 description of the overlay modes.
2841 * doc/gdk-pixbuf-sections.txt: Added the animation section. Moved
2842 the canvas item section to the end, as it will be moved later to
2845 * doc/gdk-pixbuf.sgml: Added the animation section.
2847 * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
2849 1999-12-26 Peter Teichman <pat@gnu.org>
2851 * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add
2852 $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker.
2853 This closes bug #4676.
2855 1999-12-23 Havoc Pennington <hp@pobox.com>
2857 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
2858 set to NULL here (specifically context->animation) was not being
2859 set to NULL. use g_new0() to alloc the struct.
2861 1999-12-20 Jonathan Blandford <jrb@redhat.com>
2863 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2864 correctly. Progressive loading needs some work, but that all
2865 needs doing from the gdk-pixbuf-loader end, not here.
2867 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2869 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2870 moved the file here. It seems natural to put this function here,
2871 as that's where the gdk_pixbuf_new_from_file function is, but it's
2872 still a little convoluted. The source files might be played with
2875 1999-12-14 Jonathan Blandford <jrb@redhat.com>
2877 * gdk-pixbuf/gdk-pixbuf-loader.c
2878 (gdk_pixbuf_loader_get_animation): Gets the animation from the

2883 * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
2884 before using the GdkPixbuf rendering functions. Thanks to Joe
2885 Shaw <joe@off.net> for pointing this out.
2887 1999-12-13 Federico Mena Quintero <federico@redhat.com>
2889 * gdk-pixbuf/gnome-canvas-pixbuf.c
2890 (gnome_canvas_pixbuf_class_init): Renamed arguments to
2891 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
2892 consistency with the new canvas.
2893 (PixbufPrivate): Do the same renaming in the structure fields, for
2896 * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.
2898 1999-12-12 Federico Mena Quintero <federico@redhat.com>
2900 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
2901 conditional to see whether to link $(GNOME_LIBS) or not.
2903 1999-12-10 Jonathan Blandford <jrb@redhat.com>
2905 * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API.
2907 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
2908 make a warning go away.
2910 * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations.
2912 * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for

2921 Filled in body of function.
2922 (rgbconvert): Added GdkColormap parameter, and to all conversion
2924 (convert_real_slow): New function - should convert ANY visual/data
2925 format properly, but it aint fast. Used as a fallback when an
2926 optimised routine wont match.
2927 (rgbconvert): Do very specific tests on the data format to verify
2928 properly if the optimised version will do, otherwise use the
2929 fallback function for all other data formats.
2931 * gdk-pixbuf/Makefile.am: Re-enabled building of
2932 textpixbuf-drawable.
2934 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
2935 gdk_pixbuf_get_from_drawable().
2937 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
2939 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
2940 bug on two occasions.
2941 * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu
2942 function to the generic glib one.
2944 1999-12-08 Federico Mena Quintero <federico@redhat.com>
2946 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2947 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2948 checks and API definition. The body needs filling in and it needs
2949 to do the Right Thing(tm) for pixmaps plus the given colormap and
2950 windows and their own colormaps.
2952 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2953 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
2955 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
2957 * doc/tmpl/from-drawables.sgml: Populated.
2959 * doc/gdk-pixbuf.sgml: Added the from-drawables section.
2961 * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml.
2963 * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs
2966 1999-12-07 Federico Mena Quintero <federico@redhat.com>
2968 * doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about
2969 reference counting for GdkPixbuf structures.
2971 1999-12-07 Martin Baulig <martin@home-of-linux.org>
2973 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
2974 include $(GNOME_LIBS) here.
2976 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2978 Added missing "include <string.h>" to:
2979 * gdk-pixbuf/io-ras.c
2980 * gdk-pixbuf/io-bmp.c
2981 * gdk-pixbuf/io-ico.c
2983 1999-12-06 Federico Mena Quintero <federico@redhat.com>
2985 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
2988 1999-12-05 Federico Mena Quintero <federico@redhat.com>
2990 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2991 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2992 want, send me a patch to do the conditional stuff properly.
2993 Otherwise, please read the GNOME Programming Guidelines,
2994 especially the "CVS policies" section.
2996 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
2998 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
3000 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
3002 * gdk-pixbuf/io-ico.c: Bug in palet-size
3005 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
3007 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
3008 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
3010 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
3012 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
3015 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
3016 (Windows Cursor files). These are identical to .ICO files,
3017 except for the signature and 2 extra fields for the hotspot.
3019 1999-12-03 Federico Mena Quintero <federico@redhat.com>
3021 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):
3022 Removed unused variable `item'.
3024 1999-12-03 Jonathan Blandford <jrb@redhat.com>
3026 * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
3027 explain this function better.
3029 1999-12-02 Federico Mena Quintero <federico@redhat.com>
3031 Source files moved from src/ to gdk-pixbuf/, to be consistent with
3034 * doc/Makefile.am: Modified for the new source directory.
3036 * configure.in: Likewise.
3038 * Makefile.am: Likewise.
3040 * autogen.sh: Likewise.
3042 * gdk-pixbuf/Makefile.am: Likewise.
3044 1999-12-02 Federico Mena Quintero <federico@redhat.com>

3093 * src/gdk-pixbuf-util.c: New file with utility and convenience
3094 functions for pixbufs.
3096 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c.

3104 * doc/tmpl/util.sgml: Documentation for the utility functions.
3106 1999-11-29 Owen Taylor <otaylor@redhat.com>
3108 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
3109 Keep the mask around until after we draw ... since
3110 the GC changes aren't flushed to the X server until we
3111 draw, destroying it before that may result in BadPixmap
3114 1999-11-30 Havoc Pennington <hp@pobox.com>
3116 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
3118 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
3120 1999-11-29 Federico Mena Quintero <federico@redhat.com>
3122 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
3123 should be made conditional, not blindly commented out.
3125 1999-11-29 Jonathan Blandford <jrb@redhat.com>
3127 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
3128 handle .ico files. Cool.
3130 1999-11-24 Jonathan Blandford <jrb@redhat.com>
3132 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
3135 1999-11-24 James Henstridge <james@daa.com.au>
3137 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
3138 top builddir rather than src. This still builds fine, and does not
3139 get gtk-doc into an infinite loop when trying to find all the source
3142 1999-11-23 Jonathan Blandford <jrb@redhat.com>
3144 * Removed #PRAGMA } from headers. Also, make compile if you don't
3145 have it installed, already.
3147 1999-11-22 Federico Mena Quintero <federico@redhat.com>
3149 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
3150 temporary buffer to the size of the interesction of the bounding
3151 box and the expose area, not the whole expose area. This speeds
3154 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
3155 not paint black on the mask, since we already cleared it in a
3156 single gdk_draw_rectangle() operation.
3158 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
3160 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
3162 1999-11-22 Havoc Pennington <hp@pobox.com>
3164 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
3165 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
3166 dependencies to LIBADD variables for loadable modules. Necessary
3167 for a Java dynamic loading thing to be able to figure it out.
3169 1999-11-22 Havoc Pennington <hp@pobox.com>
3171 * src/io-png.c (image_load_increment): Call the update_area
3172 callback depending on the number of rows loaded in this increment.
3174 * src/testpixbuf.c (main): slow down the progressive load demo
3176 1999-11-16 Havoc Pennington <hp@pobox.com>
3178 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
3180 1999-11-22 Jonathan Blandford <jrb@redhat.com>
3182 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
3183 for srcdir != buildir != . Beats me why; I can't figure it out.
3184 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
3186 1999-11-21 Jonathan Blandford <jrb@redhat.com>
3188 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
3189 <arjan@fenrus.demon.nl>
3191 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
3193 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
3194 Rework/reorder of the code. Each case has been separated into
3195 another function; its big but it should be quick.
3196 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
3197 opaque alpha information. Not all depths/formats have been
3198 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
3200 1999-11-17 Larry Ewing <lewing@gimp.org>
3202 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
3203 implement the bounds method correctly.
3204 (compute_viewport_affine): compute the affine need to fit the
3205 image within the viewport given by the args.
3206 (compute_render_affine): call compute_viewport_affine.
3208 1999-11-16 Havoc Pennington <hp@pobox.com>
3210 * src/gdk-pixbuf-drawable.h: Use includes from the current
3211 directory, not the system directory.
3213 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
3215 * src/testpixbuf-drawable.c: use includes from the current directory
3216 rather then from the system include directory as gdk-pixbuf
3217 includes are not yet installed when this is compiled.
3219 1999-11-13 Cody Russell <bratsche@dfw.net>
3220 * src/testpixbuf-drawable.c: Added a test program for drawable
3223 * src/Makefile.am: Build testpixbuf-drawable.
3225 1999-11-12 Cody Russell <bratsche@dfw.net>
3227 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.

3238 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3240 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
3243 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
3244 correctly. Patch from Arjan to do so.
3246 1999-11-10 Michael Fulbright <drmike@redhat.com>
3248 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
3251 * src/testpixbuf.c: Added final queued draw when done loading image.
3253 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3255 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
3258 1999-11-10 Federico Mena Quintero <federico@redhat.com>

3265 * src/io-png.c: Fixed some incompatible pointer initializations.
3267 * src/io-jpeg.c (image_load_increment): Remove unused variable.
3269 1999-11-09 Michael Fulbright <drmike@redhat.com>
3271 * src/testpixbuf.c: Fixed it to use timeout to read from file
3272 for progressive loading. Set TBF_KBPS=n, where n is the number of
3273 kilobytes/second to simulate in downloading. n has to be an integer.
3275 * src/io-jpeg.c: Slight cosmetic cleanup.
3277 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
3278 PBM loading has a similar problem and will address tomorrow.
3280 1999-11-09 Havoc Pennington <hp@pobox.com>
3282 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
3283 gdk-pixbuf-drawable stuff.
3285 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3287 * configure.in: Bumped version number to 0.4.
3289 1999-11-09 Michael Fulbright <drmike@redhat.com>
3291 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
3292 all types of PNM files now.
3294 * src/io-jpeg.c (image_load_increment): Figured out problem with
3295 loading Progressive JPEG's progressively (say that 10 times fast).
3296 Currently for Progressive JPEG's the entire image is loaded before
3297 it is displayed. libjpeg supports a fancier mechanism which I may
3300 With these changes all JPEG formats appear to load properly for me.
3302 1999-11-08 Jonathan Blandford <jrb@redhat.com>
3304 * src/io-ras.c (image_load_increment): Final patch from Arjan.
3305 Seems to do progressive loading.
3307 1999-11-08 Michael Fulbright <drmike@redhat.com>
3309 * src/io-pnm.c image_load (): Fixed so we do not create a separate
3310 pixel buffer when reading in image - we reuse the pixel data in
3311 the GdkPixbuf structure instead.
3313 1999-11-08 Michael Fulbright <drmike@redhat.com>
3315 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
3316 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
3317 I can't seem to find a utility to convert into this format.
3318 Next is to add progressive loading support for the PNM format.
3320 1999-11-07 Federico Mena Quintero <federico@redhat.com>
3322 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
3323 of the width, height, x, and y setting and pixels arguments.
3325 1999-11-05 Jonathan Blandford <jrb@redhat.com>
3327 * src/io-ras.c (image_load): third patch. Now it seems to load.
3329 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
3330 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
3332 * src/io-ras.c (image_load): new file from Arjan van de Ven
3333 <arjan@fenrus.demon.nl> to begin the ras loader.
3335 1999-11-05 Federico Mena Quintero <federico@redhat.com>
3337 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
3338 for internal use only.
3340 * doc/gdk-pixbuf.sgml: Likewise.
3342 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
3344 1999-11-05 Michael Fulbright <drmike@redhat.com>
3346 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
3347 files from a file. Next step is support for ASCII files, and
3348 then incremental loading.
3350 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3352 * Makefile.am: Added doc to SUBDIRS.
3354 1999-11-04 Michael Fulbright <drmike@redhat.com>
3356 * src/io-jpeg.c: Prettied up code slightly.
3357 * src/io-pnm.c: Start of pnm loader (from file and progressively).
3358 Doesn't do much yet (will finish tomorrow).
3359 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
3361 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3363 * doc/tmpl/rendering.sgml: Populated.
3365 * doc/Makefile.am: Added the template files.
3367 1999-11-04 Havoc Pennington <hp@pobox.com>
3369 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
3370 docs, explain what a dither offset is for.
3371 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3372 this function vs. gdk_pixbuf_render_to_drawable().
3374 1999-11-04 Havoc Pennington <hp@pobox.com>
3376 * configure.in: Use libart-config correctly; find gnome-config
3377 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3380 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3383 Patch untested in the inside-gnome-libs case, I need to commit
3384 then check out to the gnome-libs I'm using.
3386 1999-11-04 Michael Fulbright <drmike@redhat.com>
3388 * src/io-jpeg.c (image_begin_load): Add update_func callback.
3389 * src/io-jpeg.c (image_load_increment): Call updated callback when
3390 new graphic data decoded.
3392 1999-11-04 Jonathan Blandford <jrb@redhat.com>
3394 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_update): handle the
3396 * src/io-png.c (image_begin_load): add a update_func callback.
3397 * src/io-gif.c (image_begin_load): add a update_func callback.
3398 (gif_get_lzw): added the update_func ability

3402 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3404 * doc/tmpl/gdk-pixbuf.sgml: Populated.
3406 * doc/tmpl/refcounting.sgml: Populated.
3408 * doc/tmpl/file-loading.sgml: Populated.
3410 * src/gdk-pixbuf.c: Added documentation comments.
3412 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Added
3413 documentation comments.
3415 * doc/: Finished integrating the documentation framework.
3417 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3419 * configure.in: Removed libgif stuff now that we do not depend on it.
3420 Added the necessary cruft for gtk-doc.
3422 * src/Makefile.am: Unconditionally build the GIF loader.
3424 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3426 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
3427 Added a lot of comments to the file.
3429 * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
3432 1999-11-03 Michael Fulbright <drmike@redhat.com>
3434 * src/io-jpeg.c (image_load_increment): Further removal of
3435 bugginess in local buffering code. Handles grayscale jpegs
3438 * src/io-jpeg.c (image_load_stop): Was freeing local context
3439 for jpeg library before calling jpeg_decompres_finish ().
3441 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3443 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
3445 (gif_get_lzw): set the transparency to the right val.
3447 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3449 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
3450 Initiailize the x and y fields.
3451 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
3452 (PixbufPrivate): Renamed need_size_update to need_xform_update.
3453 (recompute_bounding_box): Do not use temporary values.
3455 1999-11-03 Jonathan Blandford <jrb@redhat.com>

3460 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): remove
3461 unneeded x,y,h,w vars.
3463 1999-11-03 Larry Ewing <lewing@gimp.org>
3465 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
3466 render_affine calculation for x,y offsets.
3467 (gnome_canvas_pixbuf_set_arg): add x,y args.
3468 (gnome_canvas_pixbuf_get_arg): add x,y args.
3469 (recompute_bounding_box): simply code using ArtDrect and the
3470 render_affine. Removed compute_xform_vectors as it was no longer
3473 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3475 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
3476 doofus. Return a distance, not a boolean, for opaque images.
3478 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
3479 rounding of bounding box coordinates.
3480 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
3481 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
3483 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3485 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
3487 1999-11-03 Michael Fulbright <drmike@redhat.com>
3489 * src/io-jpg.c (image_load_increment): Fixed code which moved
3490 buffer around as new data comes in to work properly. JPEG progressive
3491 loading should be working now except for grayscale JPEG's, which I
3492 will look into next.
3494 1999-11-03 <sopwith@redhat.com>
3495 * src/testpixbuf.c: A GtkFunction needs to return a value for
3496 deterministic behaviour. Also put dot printing back in.
3498 1999-11-03 <jrb@redhat.com>
3500 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
3503 1999-11-02 Cody Russell <bratsche@dfw.net>
3504 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
3505 if part of the requested image is offscreen, rather than clipping
3508 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3510 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
3511 for interlacing and progressive loading.
3513 1999-11-02 Cody Russell <bratsche@dfw.net>
3514 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
3515 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
3517 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3519 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
3520 It's a little slow though. )-:
3522 1999-11-02 Elliot Lee <sopwith@redhat.com>
3523 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the
3524 arguments to the write/load_increment operations const-correct.
3526 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3528 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
3529 Implemented the ::point() method. We do a simple containment test
3530 instead of a full distance calculation since the canvas is going
3531 to change to that scheme, anyways.
3533 1999-11-02 Elliot Lee <sopwith@redhat.com>
3535 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size
3536 of the chunks that are read from the input file.
3538 1999-11-02 Larry Ewing <lewing@gimp.org>
3540 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
3542 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
3545 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3547 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3548 affine computation code from ::draw() to here, since it is needed
3549 by ::point() as well.
3551 1999-11-02 Elliot Lee <sopwith@redhat.com>
3553 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3554 three functions, and eliminate duplication of code from write()
3555 and close(). Also fix bug where the 128-byte header was being
3558 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3559 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3560 bounding box computation.
3562 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3564 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3565 Drawing affines seem to work. Bounding box is fubared. ::point()
3566 is not implemented. This is a work in progress.
3568 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3571 * configure.in: Sigh. We need to link in libgnomeui for the
3572 canvas stuff. This mess will disappear when gdk-pixbuf gets
3573 folded into gnome-libs.
3575 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3577 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3578 the right size, at a minimum, even if the image is squished and
3580 (ReadImage): lets get the offset right. This will let transparent
3583 1999-10-29 Michael Fulbright <drmike@redhat.com>
3585 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3586 image width was not a multiple of 4 - always use the
3587 gdk_pixbuf rowstride to increment pointers!
3589 1999-10-29 Michael Fulbright <drmike@redhat.com>
3591 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3592 Currently does not handle either progressive jpeg files (jpeg
3593 files with multiple scans at different quality settings), but
3594 I plan on adding this support soon. These are fairly rare in
3595 my experience, so it shouldn't slow people down too much.
3596 Grayscale jpegs also don't work but that should be easy to fix.
3598 1999-10-29 Michael Fulbright <drmike@redhat.com>
3600 * src/testpixbuf.c: Added title to windows so you can identify
3601 progressive and file windows.
3603 1999-10-29 Michael Fulbright <drmike@redhat.com>
3605 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3606 load the image handler when we determine the image type.
3608 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3609 previously static function load_image_handler () to
3610 a public function gdk_pixbuf_load_module (). It is needed in
3611 gdk-pixbuf-loader.c to load image handler modules. This function
3612 is different from gdk_pixbuf_get_module (), which only returns
3613 a reference to the required handler, because it actually loads
3614 the handler into memory. Both actions should possibly be combined
3615 in a convenience function since one w/o the other doesn't seem to
3618 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3620 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
3623 1999-10-28 Federico Mena Quintero <federico@redhat.com>
3625 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3626 function to render a portion of a pixbuf to a drawable. Ignores
3627 alpha information and takes in a GC.
3628 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3629 portion of a pixbuf to a drawable. It automatically creates a GC
3630 and a clipping mask for alpha pixbufs.
3632 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3634 * src/gdk-pixbuf.h: turned convenience macros into convenience
3635 functions so some error checking could be added.
3637 * src/io-tiff.c (image_load_increment): started work on the tiff
3638 non-incremental loader.
3639 (image_begin_load): Finished the incremental loader.
3641 * src/io-gif.c (image_load_increment): started work on the gif
3644 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
3646 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3648 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3649 function to threshold a pixbuf's alpha channel into a bitmap.
3651 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3652 contemplate future extensions to ArtPixBuf's formats.
3654 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3656 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3657 macros to fetch the ArtPixBuf's fields.
3659 1999-10-27 Havoc Pennington <hp@pobox.com>
3661 * src/testpixbuf.c (main): Display the progressive load
3663 * src/io-png.c (setup_png_transformations): Break transformation
3664 code into separate function
3665 (png_info_callback): Use setup_png_transformations
3667 1999-10-27 Havoc Pennington <hp@pobox.com>
3669 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3670 properly whether the XPM module has already been loaded
3671 (gdk_pixbuf_new_from_file): Check properly if loader module
3672 was already loaded (was checking if load symbol was present
3673 in order to decide whether to re-load; should check module !=
3674 NULL, then load != NULL)
3675 (image_handler_load): Check in present working directory,
3676 makes it easier to debug for now
3677 (file_formats): This array initializer was seriously on crack,
3678 was assigning a function pointer to a GModule*
3680 * src/testpixbuf.c (main): Change type of pixbuf_loader to
3683 1999-10-27 Havoc Pennington <hp@pobox.com>
3685 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_finalize):
3686 Fix typo that prevented compilation

3691 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
3692 GdkPixbufLoader, not a GtkObject.
3693 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
3694 (gdk_pixbuf_loader_get_type): Documented.
3695 (gdk_pixbuf_loader_class_init): Initialize the parent class
3697 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
3698 class destroy function.
3699 (gdk_pixbuf_loader_new): Documented.
3700 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3702 (gdk_pixbuf_loader_write): Use size_t for count.
3704 1999-10-27 Michael Fulbright <drmike@redhat.com>
3706 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3707 logic so we only try to close loader if it wasn't previously closed.
3709 1999-10-27 Michael Fulbright <drmike@redhat.com>
3711 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of
3712 pixbuf_loader properly initialized.
3714 * src/testpixbuf.c: Made sure we cleanup pixbuf_loader properly
3717 1999-10-26 Jonathan Blandford <jrb@redhat.com>
3719 * src/gdk-pixbuf-io.c (image_handler_load): load the vtable fully.
3721 * src/gdk-pixbuf-loader.c: Finished initial cut at the object.

3735 1999-10-25 Federico Mena Quintero <federico@redhat.com>
3737 * configure.in (CFLAGS): Patch from Uwe Koloska
3738 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3740 1999-10-22 Havoc Pennington <hp@pobox.com>
3742 * src/io-xpm.c (mem_buffer): Clean up stupid
3743 increment-inside-array-dereference thing
3745 * src/testpixbuf.c: Add XPM data tests.
3747 * src/io-xpm.c: Make the XPM data buffer const, fix const
3748 correctness throughout the code.
3750 1999-10-22 Havoc Pennington <hp@pobox.com>
3752 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

3760 function, loads pixbuf from xpm data
3761 (image_handler_load): Add g_return_if_fail() to ensure the same
3762 module isn't loaded twice. Add g_module_symbol() to scan for XPM
3765 1999-10-22 Federico Mena Quintero <federico@redhat.com>
3767 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3768 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
3769 buffers; the rows can be read in directly into the main pixel
3772 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3774 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
3776 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3778 * configure.in: Bumped version number to 0.3.
3780 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
3781 version number for the library.
3783 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3785 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
3786 all memory management of the buffer is done by libart.
3788 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
3789 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
3791 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
3792 terms of the libart functions. Removed the old code.
3794 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
3795 symbols. Saving will not be implemented in GdkPixbuf.
3797 * src/io-gif.c: Removed the saving stub.
3798 (image_load): Fixed memory management to fail gracefully if we run
3799 out of memory while loading the image. Close the gif file when we
3800 are done. This still needs more error handling for the DGif
3803 * src/io-jpeg.c (image_load): Some robustness fixes.
3805 * src/io-png.c: Removed the saving stuff.
3806 (image_load): Some memory management fixes.
3808 * src/io-tiff.c (image_load): Ditto.
3810 * src/io-xpm.c (pixbuf_create_from_xpm): Ditto.
3812 1999-10-18 Havoc Pennington <hp@pobox.com>
3814 * subautogen.sh: New name for macros/autogen.sh
3816 * autogen.sh: use subautogen.sh
3818 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3820 * src/*: Reindented to use the GNOME Indentation. Renamed
3821 GdkPixBuf to GdkPixbuf, for consistency with the function names
3822 (and it is also easier to type) :-)
3824 1999-10-18 Havoc Pennington <hp@pobox.com>
3826 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
3828 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
3830 1999-10-18 Havoc Pennington <hp@pobox.com>
3832 * Makefile.am (SUBDIRS): Remove "macros"
3834 * configure.in: Don't use GNOME_INIT, handle case where we are
3835 inside gnome-libs. AM_PATH_GTK for the GIF test
3837 * src/Makefile.am: Change flags to work without libgnomeui,
3838 comment out testpixbuf for now
3840 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3842 * configure.in: Use $GTK_LIBS as the extra libs when checking for
3843 libgif/libungif, as they need the X libraries. Fixes bug #2472.
3845 1999-10-10 Cody Russell <bratsche@dfw.net>
3846 * src/gdk-pixbuf-drawable.c: core function now determines whether
3847 the requested geometry is on screen or not, and if some is not
3848 then the request is clamped to geometry that is on the screen.
3850 Changed 'pixbuf' to 'art_pixbuf' in core function.
3852 1999-10-08 Michael Fulbright <drmike@redhat.com>
3854 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.
3856 * src/testpifbuf: Changed test program to display cdrom from rgb data
3857 if no filename given to test program.
3859 1999-10-07 Cody Russell <bratsche@dfw.net>
3860 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
3861 them, but I wrote them).
3863 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
3866 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
3867 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.
3869 * src/gdk-pixbuf-drawable.c: Added #include "gdk-pixbuf-drawable.h"
3872 * src/gdk-pixbuf-drawable.[ch]: Changed functions to return
3873 GdkPixBuf* instead of ArtPixBuf*.

3881 GdkPixBufUnrefFunc + gdk_pixbuf_new.
3883 * src/io-jpeg.c (image_load): clean to use gdk_pixbuf_new.
3885 * src/io-xpm.c (_pixbuf_create_from_xpm): ditto.
3887 * src/io-tiff.c (image_load): ditto + fix leak
3889 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
3890 crashes this module ( add warning :-)
3892 * src/io-bmp.c (image_load): ditto.
3894 * src/io-gif.c (image_load): ditto.
3896 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
3898 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
3899 it doesn't crash scaling with alpha.
3901 1999-09-17 Federico Mena Quintero <federico@redhat.com>
3903 * src/io-bmp.c (image_load): Set the initial ref_count to 1.

3922 1999-08-09 Federico Mena Quintero <federico@nuclecu.unam.mx>
3924 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
3925 to unallocated memory (row_ptr), and fixed its type as well. Take
3926 into account the ArtPixbuf's rowstride when assigning the row
3929 * src/gdk-pixbuf.c: Fixup includes.
3931 * src/gdk-pixbuf-io.c: Likewise.
3933 Sat Jul 31 19:19:47 CEST 1999
3935 * src/gdk-pixbuf-io.c:
3936 * src/io-png.c: Fixed two obvious C syntax bugs
3938 1999-07-29 Mark Crichton <crichton@gimp.org>
3940 * src/io-png.c (image_save): Added PNG saving function
3942 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
3943 image_save(GdkPixBuf *p, FILE *f, ...)
3946 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
3948 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3949 require extra libraries if we actually have those libraries.
3951 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3953 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
3954 * gdk_pixbufConf.sh.in: Added for gnome-config
3956 * configure.in: Modified to generate gdk_pixbufConf.sh
3958 1999-07-20 Mark Crichton <crichton@gimp.org>
3960 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3961 calculation needs to be done.
3963 1999-07-18 Larry Ewing <lewing@gimp.org>
3968 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3969 error cases but one or two in the common case. There are probably
3970 a few small ones left.
3972 1999-07-18 Mark Crichton <crichton@gimp.org>
3974 * configure.in: removed version.h.
3976 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3979 1999-07-17 Mark Crichton <crichton@gimp.org>
3981 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
3982 (gdk_pixbuf_rotate): Added pixbuf rotation code.
3983 (gdk_pixbuf_scale): Changed // comments to /* */

3988 1999-07-16 Larry Ewing <lewing@gimp.org>
3990 * src/testpixbuf.c (expose_func): reverted the expose everything
3991 changes, I'm not sure why these went in.
3992 (config_func): bring this up to date with the new pixbuf_scale
3995 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3996 loading code so that poeple can diagnose problems better.
3998 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3999 no longer allocates a new pixbuf, which make things nicer for the
4000 rest of the code. Unfortunately there is still a problem with
4001 scaling rgba images.
4003 1999-07-16 Mark Crichton <crichton@gimp.org>
4005 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
4006 calls gdk_pixbuf_scale. However, something is not working.
4007 N.B.: current pixmap is now stored in user_data with a key of
4010 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
4011 Something is still borked, however.
4013 1999-07-15 Larry Ewing <lewing@gimp.org>
4015 * src/io-jpeg.c (image_load): add raph@gimp.org's fix to the jpeg
4018 * src/testpixbuf.c (main): fix up the file routines a little so
4019 that you can load multiple files given the file names
4021 1999-07-14 Larry Ewing <lewing@gimp.org>
4023 * src/testpixbuf.c (expose_func): added an almost proper expose
4024 handler for testpixbuf
4026 1999-07-13 Mark Crichton <crichton@gimp.org>
4028 * configure.in: Fixed GIF check. Replaced " with '

4031 1999-07-13 Mark Crichton <crichton@gimp.org>
4033 * configure.in: I am a bonehead. Added gif-lib check.
