524 from Matthias Clasen). Needs to be merged to GNOME
527 2002-06-13 Matthias Clasen <maclas@gmx.de>
529 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
530 incrementally display incrementally loaded progressive jpegs.
532 2002-06-07 Federico Mena Quintero <federico@ximian.com>
535 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
536 starting at a specific memory location. We do this instead of
537 GINT32_FROM_LE() as the latter is simply dereferences a cast,
538 which doesn't work on platforms with alignment requirements.
541 2002-06-01 Matthias Clasen <maclas@gmx.de>
543 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
544 with a C comment - those seem to be not uncommon, e.g. the Gimp
545 produces them. (#82706)
547 * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
549 (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.
551 2002-05-22 Tor Lillqvist <tml@iki.fi>
553 * gdk-pixbuf-io.c (get_libdir): Use GTK_BINARY_VERSION (and not
554 GTK_VERSION) in the path to the loaders on Win32, too.
556 * Makefile.am: Pass GTK_BINARY_VERSION.
558 2002-05-22 Federico Mena Quintero <federico@ximian.com>
560 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
561 account!!! Fixes #82515.
563 [This bug is not present in the GNOME 1.4 branch as its XPM loader
564 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
565 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
567 [IMPORTANT: The comment above is to make my life easier when
568 merging stuff across branches. If you make changes to gdk-pixbuf
569 in either branch, please include a comment in the ChangeLog that
570 indicates whether this should be merged into the other branch.
573 2002-05-18 Matthias Clasen <maclas@gmx.de>

588 2002-05-07 Michael Natterer <mitch@gimp.org>
590 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
591 conditionally like the dynamic ones so --without-lib<foo> is
592 honored when building with --disable-modules. (#66867)
594 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
596 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to
598 * test-loaders.c, test-images.h: remove
600 2002-04-24 Matthias Clasen <maclas@gmx.de>
602 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
603 restriction from the description of png tEXt parameters.
605 * io-png.c (png_text_to_pixbuf_option):
606 (gdk_pixbuf__png_image_save): If libpng supports it,
607 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
609 2002-04-11 Matthias Clasen <maclas@gmx.de>
611 More fixes for #77807:
613 * io-tga.c (get_contiguous_pixbuf): Helper function to create
614 a pixbuf with a contiguous pixel array while being careful about
617 * io-tga.c (fill_in_context, get_image_pseudocolor,
618 get_image_truecolor, get_image_grayscale): Use
619 get_contiguous_pixbuf instead of manually allocating image
622 * io-xpm.c (pixbuf_create_from_xpm):
623 * io-pnm.c (gdk_pixbuf__pnm_image_load):
624 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
625 instead of manually allocating image storage.
627 2002-04-09 Matthias Clasen <maclas@gmx.de>
629 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
630 priv->image_module->module_name instead of image_type which may
633 2002-04-06 Matthias Clasen <maclas@gmx.de>
635 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
636 gdk_pixbuf_new instead of manually allocating image storage. This
637 gives us a good rowstride and overflow checks. (#77807)
639 2002-04-05 Matthias Clasen <maclas@gmx.de>
641 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
642 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable
643 put functions instead of TIFFRGBAImage. And check image dimensions

650 2002-03-29 Matthias Clasen <maclas@gmx.de>
652 * io-png.c (png_simple_error_callback): libpng error handlers must
653 not return to their callers, thus longjmp out. This prevents
654 annoying stderr output from the default error handler.
656 2002-03-27 Matthias Clasen <maclas@gmx.de>
658 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
660 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
661 end_info. Also call png_read_end to check proper ending of the png
662 file and catch text chunks after the image data.
664 2002-03-27 Matthias Clasen <maclas@gmx.de>
666 * io-png.c (gdk_pixbuf__png_image_load,
667 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
668 instead of system malloc.
670 2002-03-26 Matthias Clasen <maclas@gmx.de>
672 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
674 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
675 context->buf on error.
677 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
678 stop_load even for short images to prevent memleaks.
680 2002-03-25 Matthias Clasen <maclas@gmx.de>
682 * io-png.c (setup_png_transformations): Changed signature to
683 return success and set a GError parameter, adjusted all callers.
684 Also work around a possible FPE in libpng and always check that
685 the new info is sane.
687 2002-03-23 Matthias Clasen <maclas@gmx.de>
689 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
690 context->updated_func is NULL during a nonincremental load.
691 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
693 2002-03-18 Matthias Clasen <maclas@gmx.de>
695 * io-tga.c: Fix assumptions on rowstride by manually allocating a
696 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
697 Support grayscale + alpha (which can be written, but not read (!)
700 2002-03-15 Matthias Clasen <maclas@gmx.de>
702 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
704 2002-03-13 Matthias Clasen <maclas@gmx.de>
706 * test-images.h: Add valid_ras_test and invalid_bmp_1.
708 * test-loaders.c (main): Add random tests for ras and pnm and an
709 invalid bmp which was a crasher until my 2002-03-12 commit.
711 * io-pnm.c (gdk_pixbuf__pnm_image_load_increment): Don't unref the
714 * io-ras.c: Handle some errors.
716 2002-03-12 Sven Neumann <sven@gimp.org>
718 * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
719 calling memcpy(). Simpler and potentially faster. (#70332)
721 2002-03-12 Matthias Clasen <maclas@gmx.de>
723 * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
724 which could actually be reached by a proper error status return.
726 2002-03-05 Matthias Clasen <maclas@gmx.de>
728 * test-loaders.c, test-images.h: More random tests.
730 * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.

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

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

1079 * gdk-pixbuf/gdk-pixbuf.h
1080 * gdk-pixbuf/io-jpeg.c
1081 * gdk-pixbuf/io-png.c: changed GDK_PIXBUF_ERROR_BAD_OPTION_VALUE to
1082 GDK_PIXBUF_ERROR_BAD_OPTION to we can use it for bad keys too. Added
1083 new public API gdk_pixbuf_get_option() to retrieve key/value pairs
1084 set by an image loader. Added support for saving and reading PNG tEXt
1085 chunks in PNG images.
1087 Tue Oct 2 11:29:50 2001 Owen Taylor <otaylor@redhat.com>
1089 * gdk-pixdata.c (gdk_pixdata_to_csource): Fix indentation
1090 use a macro to make code a bit more readable.
1092 2001-10-02 Sven Neumann <sven@gimp.org>
1094 * gdk-pixdata.c: g_string_printfa => g_string_append_printf.
1096 Wed Sep 26 18:08:19 2001 Owen Taylor <otaylor@redhat.com>
1098 * Makefile.am (s-enum-types-h): Fix a typo in the include
1099 guards. (#61254, Skip Montaro)
1101 2001-09-21 Matthias Clasen <matthiasc@poet.de>
1103 * io-xpm.c (xpm_extract_color): Rewritten to handle
1104 xpm colormap entries more thoroughly. (#59939)
1106 2001-09-21 Hans Breuer <hans@breuer.org>
1108 * gdk-pixbuf.def : updated externals
1110 * makefile.msc : generate gdk-pixbuf-enum-types.[hc]
1112 Thu Sep 20 17:22:48 2001 Owen Taylor <otaylor@redhat.com>
1114 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
1115 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't
1116 work here since we are using the raw file descriptor. So, we call lseek()
1117 on the fileno(f) before using it. (#60840).
1119 2001-09-20 James Henstridge <james@daa.com.au>
1121 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
1122 so that flags types are registered as flags rather than enums (not
1123 that there are any flags here at the moment).
1125 Wed Sep 19 00:28:24 2001 Owen Taylor <otaylor@redhat.com>
1127 * Makefile.am (gdk_pixbuf_headers): Don't include
1128 gkd-pixbuf-features.h here since is in builddir
1129 and confuses autogen rules.
1131 * Makefile.am: Don't += variables before they have values,
1132 automake-1.5 doesn't like it.
1134 * Makefile.am: Fix srcdir != builddir for gdk-pixbuf-enum-types.c.
1136 * Makefile.am: The whitespace strikes back.
1138 2001-09-17 Matt Wilson <msw@redhat.com>
1140 * Makefile.am (libpixbufloader_xbm_la_LDFLAGS): removed duplicate
1141 LDFLAGS definition, use the -avoid-version one.
1142 (libpixbufloader_tga_la_LDFLAGS): likewise
1144 Mon Sep 17 11:49:02 2001 Owen Taylor <otaylor@redhat.com>
1146 * pixops/*: Mirror GdkInterpType to PixopsInterpType
1147 to avoid including gdk-pixbuf headers.
1149 2001-09-16 James Henstridge <james@daa.com.au>
1151 * .cvsignore: add generated files to ignore list.
1153 * gdk-pixbuf.h: include gdk-pixbuf-enum-types.h
1155 * Makefile.am: add rules to build gdk-pixbuf-enum-types.[ch]
1157 Fri Sep 14 23:22:12 2001 Matthias Clasen <matthiasc@poet.de>
1159 * io-pnm.c (pnm_read_header): Use GDK_PIXBUF_ERROR_CORRUPT_IMAGE,
1160 not GDK_PIXBUF_ERROR_HEADER_CORRUPT. (#58308)
1162 Fri Sep 14 22:53:45 2001 Matthias Clasen <matthiasc@poet.de>
1164 * io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load): Handle
1165 out-of-memory situation better.
1167 * io-pnm.c: Robustness fixes for pnm loader
1169 * io-gif.c: Make gif loader survive TEST_RANDOMLY_MODIFY
1171 * io-xpm.c (parse_color): detect very long color strings
1173 All of the above from Matthias Clasen <matthiasc@poet.de>,
1174 the remaining from Soeren Sandmann <sandmann@daimi.au.dk>.
1176 * test-images.h: add tests:
1177 - four valid ppm's, eight invalid (matthiasc@poet.de)
1178 - one invalid xpm (matthiasc@poet.de)
1179 - one valid tga, one invalid (sandmann@daimi.au.dk)
1180 - one invalid tiff (sandmann@daimi.au.dk
1182 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
1184 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
1185 fail - detect it when it happens
1187 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
1190 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
1193 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
1195 * Makefile.am: don't used BUILT_SOURCES to build marshal
1196 files, as in conjunction with stamp files, this can
1197 lead to endless rebuilding loops.
1199 Tue Sep 4 00:22:07 2001 Owen Taylor <otaylor@redhat.com>
1201 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1
1203 Tue Sep 4 03:09:52 2001 Tim Janik <timj@gtk.org>
1205 * gdk-pixbuf-csource.1: new file, manual page for
1206 the publically installed gdk-pixbuf-csource utility.
1208 Thu Aug 30 08:30:03 2001 Matthias Clasen <matthiasc@poet.de>
1210 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Propagate
1211 errors from gdk_pixbuf_loader_load_module.
1213 Thu Aug 30 08:27:37 2001 Matthias Clasen <matthiasc@poet.de>
1215 * io-png.c (png_row_callback): Check that row_num is valid.
1217 Tue Aug 28 21:05:26 2001 Matthias Clasen <matthiasc@poet.de>
1219 * io-bmp.c (OneLine): Emit area_updated signal with proper
1220 area information. (#52002)
1222 Tue Aug 28 20:03:43 2001 Matthias Clasen <matthiasc@poet.de>
1224 * test-loaders.c (test_loader): Catch errors at close time.
1225 * test-loaders.c (main): Remove C++ comments.
1227 2001-08-21 Matthias Clasen <matthiasc@poet.de>
1229 * Makefile.am, gdk-pixbuf-io.c, pixbufloader_tga.def,
1230 io-tga.c: Add tga loader, patch by Nicola Girardi. (#56067)
1232 2001-08-20 Matthias Clasen <matthiasc@poet.de>
1234 * test-images.h, test-loaders.c: Add ico and wbmp tests.
1235 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): Fail with a suitable
1236 error if buffer allocation fails.
1237 * io-ico.c: Make .ICO loader more robust.
1238 All of these are due to sandmann@daimi.au.dk (#50187)
1240 2001-08-19 Sven Neumann <sven@gimp.org>
1242 * pixops/pixops.c: applied some simple but effective optimizations
1243 to pixops_composite_nearest() and pixops_composite_color_nearest().
1245 2001-08-07 Sven Neumann <sven@gimp.org>
1247 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
1248 function, so that's what I did.
1250 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
1252 * gdk-pixdata.c: Fix a typo.
1254 2001-07-30 Hans Breuer <hans@breuer.org>
1256 * pixops/makefile.msc : new file
1257 * makefile.msc : use it to complete the build
1259 2001-07-20 Hans Breuer <hans@breuer.org>
1261 * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
1262 pointer increment out of the macro, because at least one
1263 compiler (msvc 5.0) gets confused otherwise (applies the
1266 * gdk_pixbuf.def : updated exports
1268 * makefile.msc : reflect gdk-pixbuf-csource changes
1270 2001-07-17 Darin Adler <darin@bentspoon.com>
1272 * gdk-pixbuf-csource.c: Add missing <stdlib.h> include.
1273 * io-png.c: (setup_png_transformations): Add ifdef so we compile
1274 without warnings with G_DISABLE_CHECKS on.
1275 * io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
1277 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
1278 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
1279 unused locals and add an initial value to quiet the compiler's
1280 unintialized variable warning.
1281 * pixops/pixops.c: Put an ifdef around some dead code.
1283 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
1285 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
1286 over to the new include flags AC_SUBST(). (Problem
1287 pointed out by Mikael Hermansson.)
1289 2001-06-29 Havoc Pennington <hp@redhat.com>
1291 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): fix for
1294 Thu Jun 28 21:54:19 2001 Owen Taylor <otaylor@redhat.com>
1296 * make-inline-pixbuf.c test-gdk-pixbuf.c test-loaders.c
1297 gdk-pixbuf-csource.c: Fix args to g_type_init ().
1299 2001-06-28 Havoc Pennington <hp@pobox.com>
1301 * gdk-pixdata.c: <string.h>
1303 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
1304 also leaking memory here from g_strdup_printf?)
1306 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
1308 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
1310 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
1311 instead from gdk_pixbuf_new_from_inline().
1313 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
1314 installed API for applications that need to serialize/deserialize
1315 on their own (gimp, BEAST).
1317 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
1318 program that can dump images in CSource format and Pixbuf
1319 stream format. supports RLE encoding, MACRO formatting etc...
1322 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
1324 * Makefile.am: Actually update timestamps, so rules don't
1327 2001-06-11 Havoc Pennington <hp@redhat.com>
1329 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
1330 already includes top_builddir
1332 2001-06-08 Havoc Pennington <hp@redhat.com>
1334 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
1335 bogus g_return_if_fail
1337 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
1338 likely timeout resolution, set it to an arbitrarily-chosen short
1340 Fixes bug #55953 from warmenhoven@yahoo.com
1342 2001-06-07 Havoc Pennington <hp@redhat.com>
1344 * Makefile.am: use Owen's new way of doing stampfiles/generated
1347 2001-06-07 Havoc Pennington <hp@redhat.com>
1349 * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path
1351 2001-06-05 Havoc Pennington <hp@redhat.com>
1353 * test-loaders.c (main): use putenv not setenv, reported by
1356 2001-05-08 Havoc Pennington <hp@redhat.com>
1358 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1359 and fix behavior to still subst color if the original image
1362 2001-06-04 Havoc Pennington <hp@redhat.com>
1364 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1367 2001-06-01 Havoc Pennington <hp@redhat.com>
1369 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1370 Makes things a bit more robust, and adds test-loaders.c
1371 which is good for finding further robustness bugs to fix.
1373 * io-tiff.c: Try to work around libtiff suckiness a bit;
1374 put a giant thread lock on the whole loader,
1375 paranoically check both whether error handlers were called and
1376 also whether functions return false. Handle case where width or
1377 height is 0. Various cleanups.
1379 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1381 (png_error_callback): apparently libpng expects you to longjmp out
1384 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1385 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1387 (gif_get_lzw): check for out-of-memory
1388 (gif_prepare_lzw): catch/report an error
1389 (new_context): use try_malloc, since GifContext is nearly 70K
1390 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1391 so we don't crash later.
1393 * Makefile.am: Add test-loaders
1395 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1398 2001-05-29 Darin Adler <darin@eazel.com>
1400 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1402 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1404 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1405 fix up bmp decoder to:
1406 - adds 16 bpp bmp support (bug #53884)
1407 - adds OS/2 1.x format bmp support (bug #54964)
1408 - adds 4 bpp RLE compressed bmp support
1409 - adds 1 bpp colormap support
1410 - fixes negative height (top down) bmp support
1412 2001-05-25 Hans Breuer <hans@breuer.org>
1414 * gdk_pixbuf.def : reflect Havoc's recent api change
1416 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1418 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1419 excess $(GLIB_LIBS).
1421 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1423 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1425 2001-05-04 Havoc Pennington <hp@redhat.com>
1427 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1428 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1431 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1432 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1433 confusion of using "src" instead of "p".
1434 (pixops_composite_color_nearest): Use a more accurate (and
1435 correct, to begin with) compositing method. This cures checks
1436 showing through on images with no alpha.
1438 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1441 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1443 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1444 area_updated signal to use signed ints. Removed animation-related
1447 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1450 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1451 all the pesky details. Remove old frame-based API. Make
1452 GdkPixbufAnimation an abstract base class, derived by the loaders.
1454 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1456 * Makefile.am (LDADDS): Add $(MATH_LIB).
1458 2001-04-18 Havoc Pennington <hp@redhat.com>
1460 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1463 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1465 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1466 so we don't try to get <gtk/gtkobject.h> from standard search
1469 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1470 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1471 take gdk-pixbuf-marshal.h out of _la sources.
1473 2001-03-19 Tor Lillqvist <tml@iki.fi>
1475 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1477 * gdk_pixbuf.def: Update.
1479 * pixbufloader_*.def: Just export the fill_vtable functions now.
1481 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1483 * make-inline-pixbuf.c (main): Added logic to remove output when
1486 2001-03-14 Havoc Pennington <hp@redhat.com>
1488 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1489 from gdk-pixbuf-marshal.h, fixes parallel makes.
1491 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1493 * test-gdk-pixbuf.c: fixed includes.
1495 2001-02-18 Havoc Pennington <hp@pobox.com>
1497 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1498 (gdk_pixbuf_get_named_module): prepend underscore
1499 (gdk_pixbuf_get_module): prepend underscore
1501 2001-02-19 Havoc Pennington <hp@redhat.com>
1503 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1505 2001-02-17 Havoc Pennington <hp@pobox.com>
1507 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1509 2001-02-07 Alexander Larsson <alexl@redhat.com>
1511 * io-xpm.c (free_buffer):
1512 Use g_free, since the buffer is allocated with g_try_alloc().
1514 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1516 * gdk-pixbuf-data.c: Fixes a minor typo.
1518 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1520 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1521 we finally need the gobject->gruntime rename.
1523 * *.c: scratched calls to g_type_init(), there's simply no point in
1524 doing that, use gtk_init().
1526 2001-02-01 Havoc Pennington <hp@pobox.com>
1528 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1529 in struct to "priv" for C++
1531 2001-01-31 Havoc Pennington <hp@pobox.com>
1533 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1535 2001-01-26 Havoc Pennington <hp@redhat.com>
1537 * gdk-pixbuf-io.c (mname): fix included modules case.
1539 2001-01-22 Havoc Pennington <hp@redhat.com>
1541 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1542 from gdk_pixbuf_load_module
1544 2001-01-22 Havoc Pennington <hp@redhat.com>
1546 * Makefile.am: Add built marshaller files to support
1547 GdkPixbufLoader signals
1549 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1550 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1551 module location, rather than acting as a fallback, because we are
1552 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1554 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1556 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1557 from gtk, and add error to close(), because stop_load may do
1558 parsing of the image.
1560 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1562 * io-*.c: make individual operations static, and add fill_vtable
1563 functions which are exported. Fix the collection of type warnings
1564 that surfaced, including a number of functions that didn't
1565 properly take a GError and some that weren't
1566 const-correct. Involved adding error handling for a few loaders.
1568 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1570 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1571 a function that fills in the GdkPixbufModule vtable, instead of
1572 looking up all the image functions individually; this means we
1573 can get type safety within modules for the loader functions.
1574 Also it means you don't have to keep the statically compiled and
1575 GModule versions in sync.
1577 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1579 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1581 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1583 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1586 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1588 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1591 2001-01-20 John Harper <jsh@eazel.com>
1593 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1594 collision between Xlib's RdBitF.c and io-tiff.c
1596 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1599 [ merged from stable gdk-pixbuf module. Untested, but it
1600 compiles, and works fine in the stable module ]
1602 2001-01-18 Tor Lillqvist <tml@iki.fi>
1604 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1605 g_win32_get_package_installation_subdirectory() function. No need
1606 to include windows.h.

1620 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1621 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1622 (gdk_pixbuf_frame_copy): new function
1623 (gdk_pixbuf_frame_free): new function
1624 (gdk_pixbuf_frame_get_type): new function

1638 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1639 contained image handlers (!USE_G_MODULE). Files to save should
1640 be opened in binary mode, fopen(s, "wb").
1642 * io-xpm.c : added HAVE_UNISTD_H condition
1644 2000-11-11 Tor Lillqvist <tml@iki.fi>
1646 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1648 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1649 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1650 mktemp() and open()).
1652 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1654 2000-11-01 Havoc Pennington <hp@pobox.com>
1656 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1657 a pixbuf pointing to a subregion of another pixbuf.
1659 2000-10-16 Tor Lillqvist <tml@iki.fi>
1661 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1663 2000-10-16 Havoc Pennington <hp@redhat.com>
1665 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1666 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1667 add error reporting here also
1669 * make-inline-pixbuf.c (main): use GError
1671 * io-xpm.c: include unistd.h
1673 * gdk-pixbuf-util.c: include string.h
1675 * io-*.c: add error reporting
1677 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
1680 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
1682 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1685 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1686 a G_FILE_ERROR if we fail to write or close the file.
1688 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1689 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1690 the GError naming rules. Add GError** to load functions.
1692 2000-10-06 Havoc Pennington <hp@redhat.com>
1694 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1696 2000-10-06 Havoc Pennington <hp@redhat.com>

1724 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
1726 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
1727 last nights code was still "broken". Should now properly handle
1728 all error conditions gracefully.
1730 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
1732 * gdk-pixbuf/io-pnm.c: Rewrote.
1734 2000-09-09 Federico Mena Quintero <federico@helixcode.com>
1736 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
1737 the correct dest offset.
1739 2000-08-25 Federico Mena Quintero <federico@helixcode.com>
1741 * gdk-pixbuf/io-xpm.c: #include <unistd.h>
1743 2000-08-05 Larry Ewing <lewing@helixcode.com>
1745 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.

1749 2000-07-26 Michael Meeks <michael@helixcode.com>
1751 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
1754 2000-07-21 Larry Ewing <lewing@helixcode.com>
1756 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
1757 xpm at least supports the progressive interface like the one in
1758 io-tiff.c. This should be reimplemented as an actual progressive
1761 2000-07-19 Jonathan Blandford <jrb@redhat.com>
1763 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
1764 make it look better.
1765 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
1766 meeks to handle errors better.
1768 2000-10-07 Tor Lillqvist <tml@iki.fi>
1771 * pixbufloader_jpeg.def
1772 * pixbufloader_png.def: Add new entry points.

1776 2000-10-06 Havoc Pennington <hp@redhat.com>
1778 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
1779 consistent with gdk_pixbuf_loader_new_with_type().
1780 Return runtime error if a module is missing.
1782 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
1784 2000-10-05 Havoc Pennington <hp@redhat.com>
1786 Pixbuf saving, patch from David Welton.
1788 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
1789 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h

1793 * io-png.c (gdk_pixbuf__png_image_save): PNG save routine.
1795 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): JPEG save routine.
1797 * gdk-pixbuf-io.c (gdk_pixbuf_save):
1798 (gdk_pixbuf_savev): Implement pixbuf saving routines
1800 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
1803 * gdk-pixbuf.h: Add public save routines; add pixbuf error
1806 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
1808 2000-10-05 Dan Winship <danw@helixcode.com>
1810 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
1811 all three of these files are the JPEG image loader. (From
1814 2000-10-03 Tor Lillqvist <tml@iki.fi>
1816 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
1817 gdk-pixbuf's version number in the rule for makefile.mingw itself.
1819 * gdk_pixbuf.def: Add new entry points.
1821 2000-09-26 Havoc Pennington <hp@redhat.com>
1823 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
1824 function here, instead of putting it in a private GTK+ file.
1826 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
1827 enum here for the known formats of inlined pixbufs.
1828 Also, #define our file magic here.
1830 2000-06-23 Havoc Pennington <hp@redhat.com>
1832 * make-inline-pixbuf.c: Small program that creates C variable
1833 declarations of inline pixbuf data. This can be read
1834 by gdk_pixbuf_new_from_inline.
1836 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
1837 inline pixbuf data and create a pixbuf from it.
1839 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1841 2000-09-07 Tor Lillqvist <tml@iki.fi>
1843 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1846 2000-08-12 Tor Lillqvist <tml@iki.fi>
1848 * gdk_pixbuf.def: Add missing entry point.
1850 2000-08-10 Havoc Pennington <hp@redhat.com>
1852 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1853 (s/pixbuf_/pixbufloader_)
1855 2000-08-02 Tor Lillqvist <tml@iki.fi>
1861 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1863 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1864 one. Fix names of DLLs to have '-' instead of '_'.
1866 2000-07-31 Elliot Lee <sopwith@redhat.com>
1867 * io-wbmp.c: Some bug fixes - now tested to work.
1869 2000-07-27 Elliot Lee <sopwith@redhat.com>
1871 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1872 gdk_pixbuf_get_named_module() function to facilitate above change
1873 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1874 Implement loader for WBMP format.
1875 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1877 2000-07-23 Tor Lillqvist <tml@iki.fi>
1882 * pixops/makefile.mingw.in
1883 * pixbuf_*.def: New files.
1886 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1888 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1889 New function, to get the GTK+ installation directory from
1890 the Windows Registry, where the installation program
1891 for whatever software includes GTK+ has stored it.
1893 Used to avoid having hardcoding the directory where to look for
1894 loaders. This function is needed by gtk, too, so it should
1895 really be just in one place. Maybe a small static library
1896 one level up from here?
1898 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1899 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1900 Open file in binary mode. This *is* standard C. (No-op on Unix,
1903 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1905 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1906 mktemp() and open().
1907 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1909 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1910 pseudo-op. Conditionalise on __MINGW32__, but probably
1911 should conditionalise on Gas version instead? Or could we
1912 do without .type on all systems?
1914 * pixops/timescale.c: Use g_get_current_time()
1915 instead of gettimeofday().
1917 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1919 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1921 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1923 * gdk-pixbuf.c: Add <string.h> include.
1925 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1927 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1928 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1929 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1930 use g_object_new() instead of g_type_create_instance() which
1931 is a private function for fundamental type implementations.
1933 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1935 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1936 soname scheme for gdk-pixbuf.
1938 2000-06-21 Havoc Pennington <hp@pobox.com>
1940 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1941 (i.e. derivation is not allowed, and there are no virtual methods
1943 (gdk_pixbuf_preinit): Call g_type_init() here.
1944 (gdk_pixbuf_init): Add a user-friendly init function, for users
1945 of standalone gdk-pixbuf
1947 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1948 way GdkPixbufAnimation was done.
1950 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1951 gdk_pixbuf_finalize() from API, since these are broken and don't
1952 make sense with new GObject stuff.
1954 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1956 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1957 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1960 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1962 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1963 so I needed something to warm my thighs. Running plain infinite
1964 loops on your laptop to make it hot is not very much fun. A demo
1965 of the gdk-pixbuf scaling functions is way better, and looks
1968 * configure.in (AC_OUTPUT): Added the demo Makefile.
1970 * Makefile.am (SUBDIRS): Added the demo directory.
1972 2000-06-09 Larry Ewing <lewing@helixcode.com>
1974 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1975 setjmp for the png error handler. It seems setting the error
1976 handling functions does not avoid the jump, and so not calling
1977 setjmp was causing the incremental loader to jump into lala land.
1978 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1979 not sure this one is actually required but the docs say it must be
1980 set for every call to a png_* function.
1981 Also changed the comment to reflect the fact that setting the
1982 error handlers does _not_ avoid the longjmp.
1984 2000-06-06 Larry Ewing <lewing@helixcode.com>
1986 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1987 take frame offest into account when trying to calculate the
1988 animation bbox. Also set the width to the width not the height.
1989 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1990 calculate bbox because now we finally have all the offset
1991 information for each frame.
1993 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1995 * configure.in: add some gtk parameters to the
1996 GDK_PIXBUF_LIBĂƒĂ¯Â¿Â½Â²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1997 fight in my crusade for strange prefix compile...
1999 2000-05-30 Not Zed <NotZed@HelixCode.com>
2001 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
2002 Initialise the error handler exit routine to our own. Note this
2003 means that every function that accesses the jpeg lib on this
2004 object MUST do a setjmp.
2005 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
2006 lib for handling fatal error.
2007 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
2008 your applications dont quit if there's a jpeg error!
2010 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
2012 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
2013 from Frank de Lange <frank@unternet.org>.
2015 2000-05-09 Darin Adler <darin@eazel.com>
2017 * gdk-pixbuf/test-gdk-pixbuf.c:
2018 Fixed includes to get rid of accidental GNOME dependency.
2020 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
2021 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
2023 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
2025 * configure.in: Bumped version number to 0.8.0.
2027 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
2028 file was not being distributed.
2030 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
2032 2000-05-09 Darin Adler <darin@eazel.com>
2034 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
2035 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
2036 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
2037 formats to 32-bit formats to re-use the high bits of the color values
2038 so that white maps to full white.
2040 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
2042 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
2043 detailed information about the structure and algorithms
2044 of pixops so people can fix it instead of breaking it.
2046 2000-05-04 Darin Adler <darin@eazel.com>
2048 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
2049 (composite_pixel), (composite_line):
2050 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
2051 Now that Owen explained the algorithm, I think I implemented it
2052 right for the cases where the destination pixbuf is not opaque.
2053 The test does seem to confirm it.
2055 2000-05-04 Darin Adler <darin@eazel.com>
2057 * gdk-pixbuf/.cvsignore:
2058 * gdk-pixbuf/Makefile.am:
2059 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
2060 (load_pixel), (simple_composite_test_one),
2061 (simple_composite_test_one_type), (simple_composite_test), (main):
2062 Added some tests of composite to highlight problems in the old
2063 implementation. These tests run without any user interaction.
2064 Just do "make check".
2066 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
2067 (composite_pixel), (composite_line): Fix composite to do a textbook
2068 "A over B" composite. This was clearly the intent, and it was easy
2069 to fix the code to do it. (Note to those that read my earlier tries
2070 at a patch; this version fixes typos that were present in all
2071 my patch attempts. I checked the final version by adding more tests.)
2073 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
2075 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
2076 offset y coordinate accordining to render_y0.
2078 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
2081 2000-04-22 James Henstridge <james@daa.com.au>
2083 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
2084 package to the devel package. The only file installed in bin is
2085 gdk-pixbuf-config, which belongs in -devel. This should allow having
2086 multiple versions of the main gdk-pixbuf package installed.
2088 2000-04-17 Karl Eichwalder <ke@suse.de>
2090 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
2091 Reported by Jens Finke.
2093 2000-04-14 Tomasz KĂƒĂ¯Â¿Â½Â³opczko <kloczek@pld.org.pl>
2095 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
2096 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
2098 2000-04-13 James Henstridge <james@daa.com.au>
2100 * configure.in: when performing the configure check to see if
2101 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
2102 rather than the other way round. Also, call AC_MSG_RESULT in the
2103 even that dynamic modules were not supported.
2105 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
2107 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
2108 hook to the last unref operation.
2110 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
2111 function to set the last unref handler for a pixbuf.
2112 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
2113 It calls the pixbuf's destroy notification function and frees the
2114 GdkPixbuf structure itself.
2115 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
2118 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
2119 for the last unref handler and its user data.
2121 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
2122 g_new0() to allocate the pixbuf.
2124 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
2125 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
2126 was not specifying the `frame' argument.
2128 * gdk-pixbuf/gdk-pixbuf-animation.c
2129 (gdk_pixbuf_animation_get_width): Fixed docstring.
2130 (gdk_pixbuf_animation_get_height): Likewise.
2131 (gdk_pixbuf_animation_get_num_frames): Likewise.
2132 (gdk_pixbuf_animation_get_frames): Likewise.

2147 update the libtool version number for libgnomecanvaspixbuf as
2149 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
2150 as well, or the old ones won't work with the new stuff. Also,
2151 renamed the modules as follows.
2153 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
2154 modules are called "libpixbufloader-<format>.so" instead of
2155 "libpixbuf-<format>.so". They needed renaming so that the new
2156 loaders won't overwrite the old ones; even with the versioning
2157 stuff, the new .so symlink to the .so.1.0.0 would overwrite the

2660 (gif_get_lzw): remove memory_leak
2662 * doc/tmpl/gdk-pixbuf-loader.sgml: much longer long description
2665 2000-01-05 Owen Taylor <otaylor@redhat.com>
2667 * gdk-pixbuf/pixops/pixops.c (pixops_process): Fix computation of end of run indices.

2723 2000-01-05 Owen Taylor <otaylor@redhat.com>
2725 * gdk-pixbuf/pixops/: Directory full of pixel data scaling
2726 code that will eventually migrate into libart.
2728 * configure.in acconfig.h: Add checks for MMX compiler support
2730 * gdk-pixbuf/gdk-pixbuf.h gdk-pixbuf/gdk-pixbuf-scale.c:
2731 Nice wrapper routines for the code in pixops that operate
2732 on pixbufs instead of raw data.
2734 * gdk-pixbuf/testpixbuf-scale: Test program for scaling
2737 2000-01-05 Jonathan Blandford <jrb@redhat.com>
2739 * doc/tmpl/animation.sgml: Documentation changes.
2741 2000-01-01 Federico Mena Quintero <federico@helixcode.com>
2743 * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
2744 counting to animations. A web browser may want to share a single
2745 copy of an animated GIF if it appears multiple times in a web
2748 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
2749 animation functions here.
2750 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
2751 animation if the loader does not support multiframe loading and
2752 the single-frame load returned NULL. Check that the filename is
2753 not NULL. Updated inline documentation.
2754 (gdk_pixbuf_animation_ref): New function.
2755 (gdk_pixbuf_animation_unref): New function.
2756 Removed gdk_pixbuf_animation_destroy() in favor of reference
2759 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
2760 Prettified. Made ref_count assertion more paranoid. Check that
2761 the filename is not NULL.
2762 (gdk_pixbuf_get_module): Use guchar * and guint for buffer and
2764 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
2767 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
2768 with a reference count of 1.
2770 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
2771 gdk-pixbuf-animation.c.
2773 * doc/tmpl/animation.sgml: Populated. It is still missing a
2774 description of the overlay modes.
2776 * doc/gdk-pixbuf-sections.txt: Added the animation section. Moved
2777 the canvas item section to the end, as it will be moved later to
2780 * doc/gdk-pixbuf.sgml: Added the animation section.
2782 * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
2784 1999-12-26 Peter Teichman <pat@gnu.org>
2786 * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add
2787 $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker.
2788 This closes bug #4676.
2790 1999-12-23 Havoc Pennington <hp@pobox.com>
2792 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
2793 set to NULL here (specifically context->animation) was not being
2794 set to NULL. use g_new0() to alloc the struct.
2796 1999-12-20 Jonathan Blandford <jrb@redhat.com>
2798 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2799 correctly. Progressive loading needs some work, but that all
2800 needs doing from the gdk-pixbuf-loader end, not here.
2802 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2804 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2805 moved the file here. It seems natural to put this function here,
2806 as that's where the gdk_pixbuf_new_from_file function is, but it's
2807 still a little convoluted. The source files might be played with
2810 1999-12-14 Jonathan Blandford <jrb@redhat.com>
2812 * gdk-pixbuf/gdk-pixbuf-loader.c
2813 (gdk_pixbuf_loader_get_animation): Gets the animation from the
2816 1999-12-16 Federico Mena Quintero <federico@redhat.com>
2818 * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
2819 before using the GdkPixbuf rendering functions. Thanks to Joe
2820 Shaw <joe@off.net> for pointing this out.
2822 1999-12-13 Federico Mena Quintero <federico@redhat.com>
2824 * gdk-pixbuf/gnome-canvas-pixbuf.c
2825 (gnome_canvas_pixbuf_class_init): Renamed arguments to
2826 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
2827 consistency with the new canvas.
2828 (PixbufPrivate): Do the same renaming in the structure fields, for
2831 * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.
2833 1999-12-12 Federico Mena Quintero <federico@redhat.com>
2835 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
2836 conditional to see whether to link $(GNOME_LIBS) or not.
2838 1999-12-10 Jonathan Blandford <jrb@redhat.com>
2840 * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API.
2842 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
2843 make a warning go away.
2845 * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations.
2847 * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for
2850 1999-12-09 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2852 * gdk-pixbuf/gdk-pixbuf.h: Enable gdk_pixbuf_get_from_drawable()
2855 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
2856 Filled in body of function.
2857 (rgbconvert): Added GdkColormap parameter, and to all conversion
2859 (convert_real_slow): New function - should convert ANY visual/data
2860 format properly, but it aint fast. Used as a fallback when an
2861 optimised routine wont match.
2862 (rgbconvert): Do very specific tests on the data format to verify
2863 properly if the optimised version will do, otherwise use the
2864 fallback function for all other data formats.
2866 * gdk-pixbuf/Makefile.am: Re-enabled building of
2867 textpixbuf-drawable.
2869 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
2870 gdk_pixbuf_get_from_drawable().
2872 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
2874 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
2875 bug on two occasions.
2876 * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu
2877 function to the generic glib one.
2879 1999-12-08 Federico Mena Quintero <federico@redhat.com>
2881 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2882 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2883 checks and API definition. The body needs filling in and it needs
2884 to do the Right Thing(tm) for pixmaps plus the given colormap and
2885 windows and their own colormaps.
2887 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2888 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
2890 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
2892 * doc/tmpl/from-drawables.sgml: Populated.
2894 * doc/gdk-pixbuf.sgml: Added the from-drawables section.
2896 * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml.
2898 * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs

2903 * doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about
2904 reference counting for GdkPixbuf structures.
2906 1999-12-07 Martin Baulig <martin@home-of-linux.org>
2908 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
2909 include $(GNOME_LIBS) here.
2911 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2913 Added missing "include <string.h>" to:
2914 * gdk-pixbuf/io-ras.c
2915 * gdk-pixbuf/io-bmp.c
2916 * gdk-pixbuf/io-ico.c
2918 1999-12-06 Federico Mena Quintero <federico@redhat.com>
2920 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
2923 1999-12-05 Federico Mena Quintero <federico@redhat.com>
2925 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2926 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2927 want, send me a patch to do the conditional stuff properly.
2928 Otherwise, please read the GNOME Programming Guidelines,
2929 especially the "CVS policies" section.
2931 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
2933 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
2935 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2937 * gdk-pixbuf/io-ico.c: Bug in palet-size
2940 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
2942 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
2943 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
2945 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
2947 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
2950 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
2951 (Windows Cursor files). These are identical to .ICO files,
2952 except for the signature and 2 extra fields for the hotspot.
2954 1999-12-03 Federico Mena Quintero <federico@redhat.com>
2956 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):
2957 Removed unused variable `item'.
2959 1999-12-03 Jonathan Blandford <jrb@redhat.com>
2961 * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
2962 explain this function better.
2964 1999-12-02 Federico Mena Quintero <federico@redhat.com>
2966 Source files moved from src/ to gdk-pixbuf/, to be consistent with
2969 * doc/Makefile.am: Modified for the new source directory.
2971 * configure.in: Likewise.
2973 * Makefile.am: Likewise.
2975 * autogen.sh: Likewise.
2977 * gdk-pixbuf/Makefile.am: Likewise.
2979 1999-12-02 Federico Mena Quintero <federico@redhat.com>

3039 * doc/tmpl/util.sgml: Documentation for the utility functions.
3041 1999-11-29 Owen Taylor <otaylor@redhat.com>
3043 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
3044 Keep the mask around until after we draw ... since
3045 the GC changes aren't flushed to the X server until we
3046 draw, destroying it before that may result in BadPixmap
3049 1999-11-30 Havoc Pennington <hp@pobox.com>
3051 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
3053 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
3055 1999-11-29 Federico Mena Quintero <federico@redhat.com>
3057 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
3058 should be made conditional, not blindly commented out.
3060 1999-11-29 Jonathan Blandford <jrb@redhat.com>
3062 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
3063 handle .ico files. Cool.

3070 1999-11-24 James Henstridge <james@daa.com.au>
3072 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
3073 top builddir rather than src. This still builds fine, and does not
3074 get gtk-doc into an infinite loop when trying to find all the source
3077 1999-11-23 Jonathan Blandford <jrb@redhat.com>
3079 * Removed #PRAGMA } from headers. Also, make compile if you don't
3080 have it installed, already.
3082 1999-11-22 Federico Mena Quintero <federico@redhat.com>
3084 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
3085 temporary buffer to the size of the interesction of the bounding
3086 box and the expose area, not the whole expose area. This speeds
3089 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
3090 not paint black on the mask, since we already cleared it in a
3091 single gdk_draw_rectangle() operation.
3093 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
3095 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
3097 1999-11-22 Havoc Pennington <hp@pobox.com>
3099 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
3100 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
3101 dependencies to LIBADD variables for loadable modules. Necessary
3102 for a Java dynamic loading thing to be able to figure it out.
3104 1999-11-22 Havoc Pennington <hp@pobox.com>
3106 * src/io-png.c (image_load_increment): Call the update_area
3107 callback depending on the number of rows loaded in this increment.
3109 * src/testpixbuf.c (main): slow down the progressive load demo
3111 1999-11-16 Havoc Pennington <hp@pobox.com>
3113 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
3115 1999-11-22 Jonathan Blandford <jrb@redhat.com>
3117 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
3118 for srcdir != buildir != . Beats me why; I can't figure it out.
3119 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
3121 1999-11-21 Jonathan Blandford <jrb@redhat.com>
3123 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
3124 <arjan@fenrus.demon.nl>
3126 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
3128 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
3129 Rework/reorder of the code. Each case has been separated into
3130 another function; its big but it should be quick.
3131 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
3132 opaque alpha information. Not all depths/formats have been
3133 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
3135 1999-11-17 Larry Ewing <lewing@gimp.org>
3137 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
3138 implement the bounds method correctly.
3139 (compute_viewport_affine): compute the affine need to fit the
3140 image within the viewport given by the args.
3141 (compute_render_affine): call compute_viewport_affine.
3143 1999-11-16 Havoc Pennington <hp@pobox.com>
3145 * src/gdk-pixbuf-drawable.h: Use includes from the current
3146 directory, not the system directory.
3148 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
3150 * src/testpixbuf-drawable.c: use includes from the current directory
3151 rather then from the system include directory as gdk-pixbuf
3152 includes are not yet installed when this is compiled.
3154 1999-11-13 Cody Russell <bratsche@dfw.net>
3155 * src/testpixbuf-drawable.c: Added a test program for drawable
3158 * src/Makefile.am: Build testpixbuf-drawable.
3160 1999-11-12 Cody Russell <bratsche@dfw.net>

3173 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3175 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
3178 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
3179 correctly. Patch from Arjan to do so.
3181 1999-11-10 Michael Fulbright <drmike@redhat.com>
3183 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
3186 * src/testpixbuf.c: Added final queued draw when done loading image.
3188 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3190 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
3193 1999-11-10 Federico Mena Quintero <federico@redhat.com>
3195 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
3198 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3200 * src/io-png.c: Fixed some incompatible pointer initializations.
3202 * src/io-jpeg.c (image_load_increment): Remove unused variable.
3204 1999-11-09 Michael Fulbright <drmike@redhat.com>
3206 * src/testpixbuf.c: Fixed it to use timeout to read from file
3207 for progressive loading. Set TBF_KBPS=n, where n is the number of
3208 kilobytes/second to simulate in downloading. n has to be an integer.
3210 * src/io-jpeg.c: Slight cosmetic cleanup.
3212 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
3213 PBM loading has a similar problem and will address tomorrow.
3215 1999-11-09 Havoc Pennington <hp@pobox.com>
3217 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
3218 gdk-pixbuf-drawable stuff.
3220 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3222 * configure.in: Bumped version number to 0.4.
3224 1999-11-09 Michael Fulbright <drmike@redhat.com>
3226 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
3227 all types of PNM files now.
3229 * src/io-jpeg.c (image_load_increment): Figured out problem with
3230 loading Progressive JPEG's progressively (say that 10 times fast).
3231 Currently for Progressive JPEG's the entire image is loaded before
3232 it is displayed. libjpeg supports a fancier mechanism which I may
3235 With these changes all JPEG formats appear to load properly for me.
3237 1999-11-08 Jonathan Blandford <jrb@redhat.com>
3239 * src/io-ras.c (image_load_increment): Final patch from Arjan.
3240 Seems to do progressive loading.
3242 1999-11-08 Michael Fulbright <drmike@redhat.com>
3244 * src/io-pnm.c image_load (): Fixed so we do not create a separate
3245 pixel buffer when reading in image - we reuse the pixel data in
3246 the GdkPixbuf structure instead.
3248 1999-11-08 Michael Fulbright <drmike@redhat.com>
3250 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
3251 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
3252 I can't seem to find a utility to convert into this format.
3253 Next is to add progressive loading support for the PNM format.
3255 1999-11-07 Federico Mena Quintero <federico@redhat.com>
3257 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
3258 of the width, height, x, and y setting and pixels arguments.
3260 1999-11-05 Jonathan Blandford <jrb@redhat.com>
3262 * src/io-ras.c (image_load): third patch. Now it seems to load.

3265 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
3267 * src/io-ras.c (image_load): new file from Arjan van de Ven
3268 <arjan@fenrus.demon.nl> to begin the ras loader.
3270 1999-11-05 Federico Mena Quintero <federico@redhat.com>
3272 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
3273 for internal use only.
3275 * doc/gdk-pixbuf.sgml: Likewise.
3277 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
3279 1999-11-05 Michael Fulbright <drmike@redhat.com>
3281 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
3282 files from a file. Next step is support for ASCII files, and
3283 then incremental loading.
3285 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3287 * Makefile.am: Added doc to SUBDIRS.
3289 1999-11-04 Michael Fulbright <drmike@redhat.com>
3291 * src/io-jpeg.c: Prettied up code slightly.
3292 * src/io-pnm.c: Start of pnm loader (from file and progressively).
3293 Doesn't do much yet (will finish tomorrow).
3294 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
3296 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3298 * doc/tmpl/rendering.sgml: Populated.
3300 * doc/Makefile.am: Added the template files.
3302 1999-11-04 Havoc Pennington <hp@pobox.com>
3304 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
3305 docs, explain what a dither offset is for.
3306 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3307 this function vs. gdk_pixbuf_render_to_drawable().
3309 1999-11-04 Havoc Pennington <hp@pobox.com>
3311 * configure.in: Use libart-config correctly; find gnome-config
3312 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3315 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3318 Patch untested in the inside-gnome-libs case, I need to commit
3319 then check out to the gnome-libs I'm using.
3321 1999-11-04 Michael Fulbright <drmike@redhat.com>
3323 * src/io-jpeg.c (image_begin_load): Add update_func callback.
3324 * src/io-jpeg.c (image_load_increment): Call updated callback when
3325 new graphic data decoded.
3327 1999-11-04 Jonathan Blandford <jrb@redhat.com>
3329 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_update): handle the

3337 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3339 * doc/tmpl/gdk-pixbuf.sgml: Populated.
3341 * doc/tmpl/refcounting.sgml: Populated.
3343 * doc/tmpl/file-loading.sgml: Populated.
3345 * src/gdk-pixbuf.c: Added documentation comments.
3347 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Added
3348 documentation comments.
3350 * doc/: Finished integrating the documentation framework.
3352 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3354 * configure.in: Removed libgif stuff now that we do not depend on it.
3355 Added the necessary cruft for gtk-doc.
3357 * src/Makefile.am: Unconditionally build the GIF loader.
3359 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3361 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
3362 Added a lot of comments to the file.
3364 * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
3367 1999-11-03 Michael Fulbright <drmike@redhat.com>
3369 * src/io-jpeg.c (image_load_increment): Further removal of
3370 bugginess in local buffering code. Handles grayscale jpegs
3373 * src/io-jpeg.c (image_load_stop): Was freeing local context
3374 for jpeg library before calling jpeg_decompres_finish ().
3376 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3378 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
3380 (gif_get_lzw): set the transparency to the right val.
3382 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3384 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
3385 Initiailize the x and y fields.
3386 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
3387 (PixbufPrivate): Renamed need_size_update to need_xform_update.
3388 (recompute_bounding_box): Do not use temporary values.
3390 1999-11-03 Jonathan Blandford <jrb@redhat.com>

3395 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): remove
3396 unneeded x,y,h,w vars.
3398 1999-11-03 Larry Ewing <lewing@gimp.org>
3400 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
3401 render_affine calculation for x,y offsets.
3402 (gnome_canvas_pixbuf_set_arg): add x,y args.
3403 (gnome_canvas_pixbuf_get_arg): add x,y args.
3404 (recompute_bounding_box): simply code using ArtDrect and the
3405 render_affine. Removed compute_xform_vectors as it was no longer
3408 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3410 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
3411 doofus. Return a distance, not a boolean, for opaque images.
3413 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
3414 rounding of bounding box coordinates.
3415 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
3416 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
3418 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3420 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
3422 1999-11-03 Michael Fulbright <drmike@redhat.com>
3424 * src/io-jpg.c (image_load_increment): Fixed code which moved
3425 buffer around as new data comes in to work properly. JPEG progressive
3426 loading should be working now except for grayscale JPEG's, which I
3427 will look into next.
3429 1999-11-03 <sopwith@redhat.com>
3430 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
3431 Also put dot printing back in.
3433 1999-11-03 <jrb@redhat.com>
3435 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
3438 1999-11-02 Cody Russell <bratsche@dfw.net>
3439 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
3440 if part of the requested image is offscreen, rather than clipping
3443 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3445 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
3446 for interlacing and progressive loading.
3448 1999-11-02 Cody Russell <bratsche@dfw.net>
3449 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
3450 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
3452 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3454 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
3455 It's a little slow though. )-:
3457 1999-11-02 Elliot Lee <sopwith@redhat.com>
3458 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
3459 write/load_increment operations const-correct.
3461 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3463 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
3464 Implemented the ::point() method. We do a simple containment test
3465 instead of a full distance calculation since the canvas is going
3466 to change to that scheme, anyways.
3468 1999-11-02 Elliot Lee <sopwith@redhat.com>
3470 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
3471 that are read from the input file.
3473 1999-11-02 Larry Ewing <lewing@gimp.org>
3475 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
3477 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
3480 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3482 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3483 affine computation code from ::draw() to here, since it is needed
3484 by ::point() as well.
3486 1999-11-02 Elliot Lee <sopwith@redhat.com>
3488 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3489 three functions, and eliminate duplication of code from write()
3490 and close(). Also fix bug where the 128-byte header was being
3493 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3494 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3495 bounding box computation.
3497 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3499 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3500 Drawing affines seem to work. Bounding box is fubared. ::point()
3501 is not implemented. This is a work in progress.
3503 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3506 * configure.in: Sigh. We need to link in libgnomeui for the
3507 canvas stuff. This mess will disappear when gdk-pixbuf gets
3508 folded into gnome-libs.
3510 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3512 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3513 the right size, at a minimum, even if the image is squished and
3515 (ReadImage): lets get the offset right. This will let transparent
3518 1999-10-29 Michael Fulbright <drmike@redhat.com>
3520 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3521 image width was not a multiple of 4 - always use the
3522 gdk_pixbuf rowstride to increment pointers!
3524 1999-10-29 Michael Fulbright <drmike@redhat.com>
3526 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3527 Currently does not handle either progressive jpeg files (jpeg
3528 files with multiple scans at different quality settings), but
3529 I plan on adding this support soon. These are fairly rare in
3530 my experience, so it shouldn't slow people down too much.
3531 Grayscale jpegs also don't work but that should be easy to fix.
3533 1999-10-29 Michael Fulbright <drmike@redhat.com>
3535 * src/testpixbuf.c: Added title to windows so you can identify
3536 progressive and file windows.
3538 1999-10-29 Michael Fulbright <drmike@redhat.com>
3540 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3541 load the image handler when we determine the image type.
3543 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3544 previously static function load_image_handler () to
3545 a public function gdk_pixbuf_load_module (). It is needed in
3546 gdk-pixbuf-loader.c to load image handler modules. This function
3547 is different from gdk_pixbuf_get_module (), which only returns
3548 a reference to the required handler, because it actually loads
3549 the handler into memory. Both actions should possibly be combined
3550 in a convenience function since one w/o the other doesn't seem to
3553 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3555 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
3558 1999-10-28 Federico Mena Quintero <federico@redhat.com>
3560 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3561 function to render a portion of a pixbuf to a drawable. Ignores
3562 alpha information and takes in a GC.
3563 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3564 portion of a pixbuf to a drawable. It automatically creates a GC
3565 and a clipping mask for alpha pixbufs.
3567 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3569 * src/gdk-pixbuf.h: turned convenience macros into convenience
3570 functions so some error checking could be added.
3572 * src/io-tiff.c (image_load_increment): started work on the tiff
3573 non-incremental loader.
3574 (image_begin_load): Finished the incremental loader.
3576 * src/io-gif.c (image_load_increment): started work on the gif
3579 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
3581 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3583 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3584 function to threshold a pixbuf's alpha channel into a bitmap.
3586 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3587 contemplate future extensions to ArtPixBuf's formats.
3589 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3591 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3592 macros to fetch the ArtPixBuf's fields.
3594 1999-10-27 Havoc Pennington <hp@pobox.com>
3596 * src/testpixbuf.c (main): Display the progressive load
3598 * src/io-png.c (setup_png_transformations): Break transformation
3599 code into separate function
3600 (png_info_callback): Use setup_png_transformations
3602 1999-10-27 Havoc Pennington <hp@pobox.com>
3604 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3605 properly whether the XPM module has already been loaded
3606 (gdk_pixbuf_new_from_file): Check properly if loader module
3607 was already loaded (was checking if load symbol was present
3608 in order to decide whether to re-load; should check module !=
3609 NULL, then load != NULL)
3610 (image_handler_load): Check in present working directory,
3611 makes it easier to debug for now
3612 (file_formats): This array initializer was seriously on crack,
3613 was assigning a function pointer to a GModule*
3615 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
3617 1999-10-27 Havoc Pennington <hp@pobox.com>

3632 class destroy function.
3633 (gdk_pixbuf_loader_new): Documented.
3634 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3636 (gdk_pixbuf_loader_write): Use size_t for count.
3638 1999-10-27 Michael Fulbright <drmike@redhat.com>
3640 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3641 logic so we only try to close loader if it wasn't previously closed.
3643 1999-10-27 Michael Fulbright <drmike@redhat.com>
3645 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of
3646 pixbuf_loader properly initialized.
3648 * src/testpixbuf.c: Made sure we cleanup pixbuf_loader properly
3651 1999-10-26 Jonathan Blandford <jrb@redhat.com>

3672 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3674 1999-10-22 Havoc Pennington <hp@pobox.com>
3676 * src/io-xpm.c (mem_buffer): Clean up stupid
3677 increment-inside-array-dereference thing
3679 * src/testpixbuf.c: Add XPM data tests.
3681 * src/io-xpm.c: Make the XPM data buffer const, fix const
3682 correctness throughout the code.
3684 1999-10-22 Havoc Pennington <hp@pobox.com>
3686 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

3701 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3702 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
3703 buffers; the rows can be read in directly into the main pixel
3706 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3708 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
3710 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3712 * configure.in: Bumped version number to 0.3.
3714 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
3715 version number for the library.
3717 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3719 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
3720 all memory management of the buffer is done by libart.

3726 terms of the libart functions. Removed the old code.
3728 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
3729 symbols. Saving will not be implemented in GdkPixbuf.
3731 * src/io-gif.c: Removed the saving stub.
3732 (image_load): Fixed memory management to fail gracefully if we run
3733 out of memory while loading the image. Close the gif file when we
3734 are done. This still needs more error handling for the DGif
3737 * src/io-jpeg.c (image_load): Some robustness fixes.
3739 * src/io-png.c: Removed the saving stuff.
3740 (image_load): Some memory management fixes.

3750 * autogen.sh: use subautogen.sh
3752 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3754 * src/*: Reindented to use the GNOME Indentation. Renamed
3755 GdkPixBuf to GdkPixbuf, for consistency with the function names
3756 (and it is also easier to type) :-)
3758 1999-10-18 Havoc Pennington <hp@pobox.com>
3760 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
3762 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
3764 1999-10-18 Havoc Pennington <hp@pobox.com>
3766 * Makefile.am (SUBDIRS): Remove "macros"
3768 * configure.in: Don't use GNOME_INIT, handle case where we are
3769 inside gnome-libs. AM_PATH_GTK for the GIF test

3772 comment out testpixbuf for now
3774 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3776 * configure.in: Use $GTK_LIBS as the extra libs when checking for
3777 libgif/libungif, as they need the X libraries. Fixes bug #2472.
3779 1999-10-10 Cody Russell <bratsche@dfw.net>
3780 * src/gdk-pixbuf-drawable.c: core function now determines whether
3781 the requested geometry is on screen or not, and if some is not
3782 then the request is clamped to geometry that is on the screen.
3784 Changed 'pixbuf' to 'art_pixbuf' in core function.
3786 1999-10-08 Michael Fulbright <drmike@redhat.com>
3788 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

3791 if no filename given to test program.
3793 1999-10-07 Cody Russell <bratsche@dfw.net>
3794 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
3795 them, but I wrote them).

3865 * src/gdk-pixbuf-io.c: Likewise.
3867 Sat Jul 31 19:19:47 CEST 1999

3882 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3883 require extra libraries if we actually have those libraries.
3885 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3887 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes

3890 * configure.in: Modified to generate gdk_pixbufConf.sh
3892 1999-07-20 Mark Crichton <crichton@gimp.org>
3894 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3895 calculation needs to be done.
3897 1999-07-18 Larry Ewing <lewing@gimp.org>
3902 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3903 error cases but one or two in the common case. There are probably
3904 a few small ones left.
3906 1999-07-18 Mark Crichton <crichton@gimp.org>
3908 * configure.in: removed version.h.
3910 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3913 1999-07-17 Mark Crichton <crichton@gimp.org>

3924 * src/testpixbuf.c (expose_func): reverted the expose everything
3925 changes, I'm not sure why these went in.
3926 (config_func): bring this up to date with the new pixbuf_scale
3929 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3930 loading code so that poeple can diagnose problems better.
3932 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3933 no longer allocates a new pixbuf, which make things nicer for the
3934 rest of the code. Unfortunately there is still a problem with
3935 scaling rgba images.
3937 1999-07-16 Mark Crichton <crichton@gimp.org>
3939 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3940 calls gdk_pixbuf_scale. However, something is not working.
3941 N.B.: current pixmap is now stored in user_data with a key of
3944 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
3945 Something is still borked, however.

3953 that you can load multiple files given the file names
3955 1999-07-14 Larry Ewing <lewing@gimp.org>
3957 * src/testpixbuf.c (expose_func): added an almost proper expose
3958 handler for testpixbuf
3960 1999-07-13 Mark Crichton <crichton@gimp.org>
3962 * configure.in: Fixed GIF check. Replaced " with '
3963 * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale
3965 1999-07-13 Mark Crichton <crichton@gimp.org>
3967 * configure.in: I am a bonehead. Added gif-lib check.
