3 * gdk-pixbuf-io.c (format_check): Interpret patterns where
4 the first byte of the mask is '*' as unanchored. (#311011)
5 (gdk_pixbuf_new_from_file): Use the first 256 bytes for
6 sniffing the file format.
8 2005-07-15 Matthias Clasen <mclasen@redhat.com>
10 * === Released 2.7.3 ===
12 2005-07-12 Matthias Clasen <mclasen@redhat.com>
15 * pixops/*: Add copyright and license information.
17 2005-07-09 Tor Lillqvist <tml@novell.com>
19 * Makefile.am: Don't use the scripts in build/win32 to compile the
20 rc file into a resource object file. (This means we lose the
21 build number increment magic, but I doubt it was that useful
22 anyway.) Instead use windres directly. To pass the normal .o file
23 produced by windres through libtool, which would want a .lo file,
24 pass it directly to the linker using a -Wl option.
26 * gdk_pixbuf.rc.in: Replace BUILDNUMBER with 0.

40 (#309258, Mark McLoughlin)
42 2005-06-26 Tor Lillqvist <tml@novell.com>
44 * Makefile.am: Current GNU tools do understand the PRIVATE
45 keyword, so no need to remove those entries from the import
46 library. libtool installs the .dll.a import library itself, so no
47 need to do it here. Do install the .def file.
49 2005-06-22 Matthias Clasen <mclasen@redhat.com>

89 * io-png.c: allow to specify the PNG compression level by passing
90 a "compression" parameter to the PNG save function (bug #305337).
92 * gdk-pixbuf-io.c (gdk_pixbuf_save): document the new parameter.
94 2005-04-09 Matthias Clasen <mclasen@redhat.com>

122 2005-03-27 Matthias Clasen <mclasen@redhat.com>

148 * gdk-pixbuf.symbols: Group symbols by header and source file.
149 * /makegdkpixbufalias.pl: Protect definitions by the same
150 preprocessor symbols used to guard the headers. Move
151 the alias declarations to a separate file which is
152 produced when calling makegdkpixbufalias.pl -def
153 * Makefile.am (gdk-pixbuf-aliasdef.c): Add a rule to generate
155 * *.c: Include gdk-pixbuf-alias.h after the other headers,
156 include gdk-pixbuf-aliasdef.c at the bottom.
158 2005-03-10 Tor Lillqvist <tml@novell.com>
162 * gdk-pixbuf.symbols: Implement DLL ABI stablility for

305 * gdk-pixbuf-animation.c: Like in GLib, for DLL ABI stability on
306 Windows, add binary compatibility versions of functions that take
307 file names as arguments. They use the system codepage, not GLib

344 to be consistent with all the other error_quark functions.
345 (technically they are const, but since these are called only
346 in error paths, giving the compiler better optimization
347 opportunities doesn't matter much)

369 lock was actually taken.
371 * queryloaders.c (query_module): Set vtable->module before
372 calling fill_vtable(), since gdk-pixbuf-io.c does does the
373 same and modules may rely on it. (#158177, Dan Winship)

810 * gdk-pixbuf-io.c: removed unnecessary G_OBJECT() cast checks.
812 * io-jpeg.c: make the return type for to_callback_empty_output_buffer
813 "boolean", which should be defined by the jpeg headers. The right

898 even if the module can't make use of the scaling information. If
899 size_func returns 0, don't allocate a pixbuf and return, if
900 necessary with an error.

939 Sun Nov 9 23:07:05 2003 Matthias Clasen <maclas@gmx.de>
941 * gdk-pixbuf-io.c (_gdk_pixbuf_generic_image_load): If neither

1025 single-image ICOs are produced, but the code for multi-image ICOs
1026 is already in place. The saver understands the options "depth"
1027 (can be "32", "24" or "16") and "x_hot"/"y_hot" for hotspot

1529 All of this needs to be merged to GNOME 1.4 gdk-pixbuf.
1531 2002-06-28 Sven Neumann <sven@gimp.org>

1538 involved, we scaled rather than composited, but then
1539 went ahead and composited anyways. (#76958, Patch
1540 from Matthias Clasen). Needs to be merged to GNOME
1543 2002-06-13 Matthias Clasen <maclas@gmx.de>
1545 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
1546 incrementally display incrementally loaded progressive jpegs.
1548 2002-06-07 Federico Mena Quintero <federico@ximian.com>
1550 * io-bmp.c (lsb_32):
1551 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
1552 starting at a specific memory location. We do this instead of
1553 GINT32_FROM_LE() as the latter is simply dereferences a cast,
1554 which doesn't work on platforms with alignment requirements.
1557 2002-06-01 Matthias Clasen <maclas@gmx.de>
1559 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting

1574 2002-05-22 Federico Mena Quintero <federico@ximian.com>
1576 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
1577 account!!! Fixes #82515.
1579 [This bug is not present in the GNOME 1.4 branch as its XPM loader
1580 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
1581 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
1583 [IMPORTANT: The comment above is to make my life easier when
1584 merging stuff across branches. If you make changes to gdk-pixbuf
1585 in either branch, please include a comment in the ChangeLog that
1586 indicates whether this should be merged into the other branch.

1604 2002-05-07 Michael Natterer <mitch@gimp.org>
1606 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
1607 conditionally like the dynamic ones so --without-lib<foo> is
1608 honored when building with --disable-modules. (#66867)
1610 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
1612 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to

1618 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
1619 restriction from the description of png tEXt parameters.
1621 * io-png.c (png_text_to_pixbuf_option):
1622 (gdk_pixbuf__png_image_save): If libpng supports it,
1623 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)

1627 More fixes for #77807:
1629 * io-tga.c (get_contiguous_pixbuf): Helper function to create
1630 a pixbuf with a contiguous pixel array while being careful about
1633 * io-tga.c (fill_in_context, get_image_pseudocolor,
1634 get_image_truecolor, get_image_grayscale): Use
1635 get_contiguous_pixbuf instead of manually allocating image
1638 * io-xpm.c (pixbuf_create_from_xpm):
1639 * io-pnm.c (gdk_pixbuf__pnm_image_load):
1640 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
1641 instead of manually allocating image storage.
1643 2002-04-09 Matthias Clasen <maclas@gmx.de>
1645 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
1646 priv->image_module->module_name instead of image_type which may
1649 2002-04-06 Matthias Clasen <maclas@gmx.de>
1651 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
1652 gdk_pixbuf_new instead of manually allocating image storage. This
1653 gives us a good rowstride and overflow checks. (#77807)
1655 2002-04-05 Matthias Clasen <maclas@gmx.de>
1657 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
1658 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable
1659 put functions instead of TIFFRGBAImage. And check image dimensions
1662 2002-04-03 Matthias Clasen <maclas@gmx.de>
1664 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_type): Fix a doc typo.
1666 2002-03-29 Matthias Clasen <maclas@gmx.de>
1668 * io-png.c (png_simple_error_callback): libpng error handlers must
1669 not return to their callers, thus longjmp out. This prevents
1670 annoying stderr output from the default error handler.
1672 2002-03-27 Matthias Clasen <maclas@gmx.de>
1674 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
1676 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
1677 end_info. Also call png_read_end to check proper ending of the png
1678 file and catch text chunks after the image data.
1680 2002-03-27 Matthias Clasen <maclas@gmx.de>
1682 * io-png.c (gdk_pixbuf__png_image_load,
1683 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
1684 instead of system malloc.
1686 2002-03-26 Matthias Clasen <maclas@gmx.de>
1688 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
1690 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
1691 context->buf on error.
1693 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
1694 stop_load even for short images to prevent memleaks.
1696 2002-03-25 Matthias Clasen <maclas@gmx.de>
1698 * io-png.c (setup_png_transformations): Changed signature to
1699 return success and set a GError parameter, adjusted all callers.
1700 Also work around a possible FPE in libpng and always check that
1701 the new info is sane.
1703 2002-03-23 Matthias Clasen <maclas@gmx.de>
1705 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
1706 context->updated_func is NULL during a nonincremental load.
1707 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
1709 2002-03-18 Matthias Clasen <maclas@gmx.de>
1711 * io-tga.c: Fix assumptions on rowstride by manually allocating a
1712 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
1713 Support grayscale + alpha (which can be written, but not read (!)
1716 2002-03-15 Matthias Clasen <maclas@gmx.de>
1718 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
1720 2002-03-13 Matthias Clasen <maclas@gmx.de>
1722 * test-images.h: Add valid_ras_test and invalid_bmp_1.
1724 * test-loaders.c (main): Add random tests for ras and pnm and an
1725 invalid bmp which was a crasher until my 2002-03-12 commit.
1727 * io-pnm.c (gdk_pixbuf__pnm_image_load_increment): Don't unref the
1730 * io-ras.c: Handle some errors.
1732 2002-03-12 Sven Neumann <sven@gimp.org>
1734 * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
1735 calling memcpy(). Simpler and potentially faster. (#70332)
1737 2002-03-12 Matthias Clasen <maclas@gmx.de>
1739 * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
1740 which could actually be reached by a proper error status return.
1742 2002-03-05 Matthias Clasen <maclas@gmx.de>
1744 * test-loaders.c, test-images.h: More random tests.
1746 * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.

1754 Sat Mar 2 22:11:10 2002 Owen Taylor <otaylor@redhat.com>
1756 * gdk-pixbuf-io.c (_gdk_pixbuf_load_module): If we
1757 can't load the module using the g_module_build_path()
1758 filename, try loading it as a .la file.
1760 * test-loaders.c: Look for modules in current directory
1761 rather than .libs, so we find the right .la files.
1763 * test-loaders.c: Back out some accidental commits.
1765 Sat Mar 2 21:28:03 2002 Owen Taylor <otaylor@redhat.com>

1803 bilinear_make_weights): Use correct_total.
1805 2002-02-10 Matthias Clasen <maclas@gmx.de>
1807 * test-images.h (tiff1_test_3), test-loaders.c (main): Add a

1816 beyond the end of buffer if width % 8 != 0.
1818 * io-tga.c (try_preload): Enforce that ctx->hdr->type is one of
1819 the supported types, otherwise parse_data_for_row () will not make

2086 * gdk-pixbuf.h, gdk-pixdata.c: Rename gdk_pixbuf_new_from_stream()
2087 back to gdk_pixbuf_new_from_inline(). Rework docs to try

2092 * gdk-pixbuf/gdk-pixbuf-io.c
2093 * gdk-pixbuf/gdk-pixbuf-private.h
2094 * gdk-pixbuf/gdk-pixbuf.c
2095 * gdk-pixbuf/gdk-pixbuf.h
2096 * gdk-pixbuf/io-jpeg.c
2097 * gdk-pixbuf/io-png.c: changed GDK_PIXBUF_ERROR_BAD_OPTION_VALUE to
2098 GDK_PIXBUF_ERROR_BAD_OPTION to we can use it for bad keys too. Added
2099 new public API gdk_pixbuf_get_option() to retrieve key/value pairs
2100 set by an image loader. Added support for saving and reading PNG tEXt
2101 chunks in PNG images.
2103 Tue Oct 2 11:29:50 2001 Owen Taylor <otaylor@redhat.com>
2105 * gdk-pixdata.c (gdk_pixdata_to_csource): Fix indentation
2106 use a macro to make code a bit more readable.
2108 2001-10-02 Sven Neumann <sven@gimp.org>
2110 * gdk-pixdata.c: g_string_printfa => g_string_append_printf.

2128 Thu Sep 20 17:22:48 2001 Owen Taylor <otaylor@redhat.com>
2130 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
2131 works in some on-demand way, so the fseek
2132 gdk_pixbuf_new_from_file() doesn't work here since we are using
2133 the raw file descriptor. So, we call lseek() on the fileno(f)
2134 before using it. (#60840).
2136 2001-09-20 James Henstridge <james@daa.com.au>
2138 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
2139 so that flags types are registered as flags rather than enums (not
2140 that there are any flags here at the moment).
2142 Wed Sep 19 00:28:24 2001 Owen Taylor <otaylor@redhat.com>
2144 * Makefile.am (gdk_pixbuf_headers): Don't include
2145 gkd-pixbuf-features.h here since is in builddir
2146 and confuses autogen rules.
2148 * Makefile.am: Don't += variables before they have values,
2149 automake-1.5 doesn't like it.
2151 * Makefile.am: Fix srcdir != builddir for gdk-pixbuf-enum-types.c.
2153 * Makefile.am: The whitespace strikes back.
2155 2001-09-17 Matt Wilson <msw@redhat.com>
2157 * Makefile.am (libpixbufloader_xbm_la_LDFLAGS): removed duplicate
2158 LDFLAGS definition, use the -avoid-version one.

2174 Fri Sep 14 23:22:12 2001 Matthias Clasen <matthiasc@poet.de>
2176 * io-pnm.c (pnm_read_header): Use GDK_PIXBUF_ERROR_CORRUPT_IMAGE,
2177 not GDK_PIXBUF_ERROR_HEADER_CORRUPT. (#58308)
2179 Fri Sep 14 22:53:45 2001 Matthias Clasen <matthiasc@poet.de>
2181 * io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load): Handle
2182 out-of-memory situation better.
2184 * io-pnm.c: Robustness fixes for pnm loader
2186 * io-gif.c: Make gif loader survive TEST_RANDOMLY_MODIFY
2188 * io-xpm.c (parse_color): detect very long color strings
2190 All of the above from Matthias Clasen <matthiasc@poet.de>,
2191 the remaining from Soeren Sandmann <sandmann@daimi.au.dk>.
2193 * test-images.h: add tests:
2194 - four valid ppm's, eight invalid (matthiasc@poet.de)
2195 - one invalid xpm (matthiasc@poet.de)
2196 - one valid tga, one invalid (sandmann@daimi.au.dk)
2197 - one invalid tiff (sandmann@daimi.au.dk
2199 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
2201 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
2202 fail - detect it when it happens
2204 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
2207 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
2210 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
2212 * Makefile.am: don't used BUILT_SOURCES to build marshal
2213 files, as in conjunction with stamp files, this can
2214 lead to endless rebuilding loops.
2216 Tue Sep 4 00:22:07 2001 Owen Taylor <otaylor@redhat.com>
2218 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1
2220 Tue Sep 4 03:09:52 2001 Tim Janik <timj@gtk.org>
2222 * gdk-pixbuf-csource.1: new file, manual page for
2223 the publically installed gdk-pixbuf-csource utility.
2225 Thu Aug 30 08:30:03 2001 Matthias Clasen <matthiasc@poet.de>
2227 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Propagate

2244 2001-08-21 Matthias Clasen <matthiasc@poet.de>
2246 * Makefile.am, gdk-pixbuf-io.c, pixbufloader_tga.def,
2247 io-tga.c: Add tga loader, patch by Nicola Girardi. (#56067)
2249 2001-08-20 Matthias Clasen <matthiasc@poet.de>
2251 * test-images.h, test-loaders.c: Add ico and wbmp tests.
2252 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): Fail with a suitable
2253 error if buffer allocation fails.
2254 * io-ico.c: Make .ICO loader more robust.
2255 All of these are due to sandmann@daimi.au.dk (#50187)
2257 2001-08-19 Sven Neumann <sven@gimp.org>
2259 * pixops/pixops.c: applied some simple but effective optimizations
2260 to pixops_composite_nearest() and pixops_composite_color_nearest().
2262 2001-08-07 Sven Neumann <sven@gimp.org>
2264 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
2265 function, so that's what I did.
2267 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
2269 * gdk-pixdata.c: Fix a typo.
2271 2001-07-30 Hans Breuer <hans@breuer.org>
2273 * pixops/makefile.msc : new file
2274 * makefile.msc : use it to complete the build
2276 2001-07-20 Hans Breuer <hans@breuer.org>
2278 * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
2279 pointer increment out of the macro, because at least one
2280 compiler (msvc 5.0) gets confused otherwise (applies the
2283 * gdk_pixbuf.def : updated exports
2285 * makefile.msc : reflect gdk-pixbuf-csource changes
2287 2001-07-17 Darin Adler <darin@bentspoon.com>
2289 * gdk-pixbuf-csource.c: Add missing <stdlib.h> include.
2290 * io-png.c: (setup_png_transformations): Add ifdef so we compile
2291 without warnings with G_DISABLE_CHECKS on.
2292 * io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
2294 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
2295 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
2296 unused locals and add an initial value to quiet the compiler's
2297 unintialized variable warning.
2298 * pixops/pixops.c: Put an ifdef around some dead code.
2300 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
2302 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
2303 over to the new include flags AC_SUBST(). (Problem
2304 pointed out by Mikael Hermansson.)
2306 2001-06-29 Havoc Pennington <hp@redhat.com>
2308 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): fix for
2311 Thu Jun 28 21:54:19 2001 Owen Taylor <otaylor@redhat.com>
2313 * make-inline-pixbuf.c test-gdk-pixbuf.c test-loaders.c
2314 gdk-pixbuf-csource.c: Fix args to g_type_init ().
2316 2001-06-28 Havoc Pennington <hp@pobox.com>
2318 * gdk-pixdata.c: <string.h>
2320 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
2321 also leaking memory here from g_strdup_printf?)
2323 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
2325 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
2327 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
2328 instead from gdk_pixbuf_new_from_inline().
2330 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
2331 installed API for applications that need to serialize/deserialize
2332 on their own (gimp, BEAST).
2334 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
2335 program that can dump images in CSource format and Pixbuf
2336 stream format. supports RLE encoding, MACRO formatting etc...
2339 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
2341 * Makefile.am: Actually update timestamps, so rules don't
2344 2001-06-11 Havoc Pennington <hp@redhat.com>
2346 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
2347 already includes top_builddir
2349 2001-06-08 Havoc Pennington <hp@redhat.com>
2351 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
2352 bogus g_return_if_fail
2354 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
2355 likely timeout resolution, set it to an arbitrarily-chosen short
2357 Fixes bug #55953 from warmenhoven@yahoo.com
2359 2001-06-07 Havoc Pennington <hp@redhat.com>
2361 * Makefile.am: use Owen's new way of doing stampfiles/generated
2364 2001-06-07 Havoc Pennington <hp@redhat.com>
2366 * Makefile.am (gdk-pixbuf-marshal.c): fix up the glib-genmarshal path
2368 2001-06-05 Havoc Pennington <hp@redhat.com>
2370 * test-loaders.c (main): use putenv not setenv, reported by
2373 2001-05-08 Havoc Pennington <hp@redhat.com>
2375 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
2376 and fix behavior to still subst color if the original image
2379 2001-06-04 Havoc Pennington <hp@redhat.com>
2381 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
2384 2001-06-01 Havoc Pennington <hp@redhat.com>
2386 Apply patch from sandmann@daimi.au.dk, with some tweaks.
2387 Makes things a bit more robust, and adds test-loaders.c
2388 which is good for finding further robustness bugs to fix.
2390 * io-tiff.c: Try to work around libtiff suckiness a bit;
2391 put a giant thread lock on the whole loader,
2392 paranoically check both whether error handlers were called and
2393 also whether functions return false. Handle case where width or
2394 height is 0. Various cleanups.
2396 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
2398 (png_error_callback): apparently libpng expects you to longjmp out
2401 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
2402 (lzw_read_byte): change "Mail jrb if this fails" g_warning
2404 (gif_get_lzw): check for out-of-memory
2405 (gif_prepare_lzw): catch/report an error
2406 (new_context): use try_malloc, since GifContext is nearly 70K
2407 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
2408 so we don't crash later.
2410 * Makefile.am: Add test-loaders
2412 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
2415 2001-05-29 Darin Adler <darin@eazel.com>
2417 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
2419 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
2421 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
2422 fix up bmp decoder to:
2423 - adds 16 bpp bmp support (bug #53884)
2424 - adds OS/2 1.x format bmp support (bug #54964)
2425 - adds 4 bpp RLE compressed bmp support
2426 - adds 1 bpp colormap support
2427 - fixes negative height (top down) bmp support
2429 2001-05-25 Hans Breuer <hans@breuer.org>
2431 * gdk_pixbuf.def : reflect Havoc's recent api change
2433 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
2435 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
2436 excess $(GLIB_LIBS).
2438 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
2440 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
2442 2001-05-04 Havoc Pennington <hp@redhat.com>
2444 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
2445 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
2448 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
2449 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
2450 confusion of using "src" instead of "p".
2451 (pixops_composite_color_nearest): Use a more accurate (and
2452 correct, to begin with) compositing method. This cures checks
2453 showing through on images with no alpha.
2455 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
2458 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
2460 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
2461 area_updated signal to use signed ints. Removed animation-related
2464 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
2467 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
2468 all the pesky details. Remove old frame-based API. Make
2469 GdkPixbufAnimation an abstract base class, derived by the loaders.
2471 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
2473 * Makefile.am (LDADDS): Add $(MATH_LIB).
2475 2001-04-18 Havoc Pennington <hp@redhat.com>
2477 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
2480 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
2482 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
2483 so we don't try to get <gtk/gtkobject.h> from standard search
2486 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
2487 add gdk-pixbuf-marshal.list to EXTRA_DIST.
2488 take gdk-pixbuf-marshal.h out of _la sources.
2490 2001-03-19 Tor Lillqvist <tml@iki.fi>
2492 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
2494 * gdk_pixbuf.def: Update.
2496 * pixbufloader_*.def: Just export the fill_vtable functions now.
2498 2001-03-18 Mike Kestner <mkestner@ameritech.net>
2500 * make-inline-pixbuf.c (main): Added logic to remove output when
2503 2001-03-14 Havoc Pennington <hp@redhat.com>
2505 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
2506 from gdk-pixbuf-marshal.h, fixes parallel makes.
2508 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
2510 * test-gdk-pixbuf.c: fixed includes.
2512 2001-02-18 Havoc Pennington <hp@pobox.com>
2514 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
2515 (gdk_pixbuf_get_named_module): prepend underscore
2516 (gdk_pixbuf_get_module): prepend underscore
2518 2001-02-19 Havoc Pennington <hp@redhat.com>
2520 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
2522 2001-02-17 Havoc Pennington <hp@pobox.com>
2524 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
2526 2001-02-07 Alexander Larsson <alexl@redhat.com>
2528 * io-xpm.c (free_buffer):
2529 Use g_free, since the buffer is allocated with g_try_alloc().
2531 2001-02-06 Christophe Merlet <redfox@eikonex.org>
2533 * gdk-pixbuf-data.c: Fixes a minor typo.
2535 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
2537 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
2538 we finally need the gobject->gruntime rename.
2540 * *.c: scratched calls to g_type_init(), there's simply no point in
2541 doing that, use gtk_init().
2543 2001-02-01 Havoc Pennington <hp@pobox.com>
2545 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
2546 in struct to "priv" for C++
2548 2001-01-31 Havoc Pennington <hp@pobox.com>
2550 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
2552 2001-01-26 Havoc Pennington <hp@redhat.com>
2554 * gdk-pixbuf-io.c (mname): fix included modules case.
2556 2001-01-22 Havoc Pennington <hp@redhat.com>
2558 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
2559 from gdk_pixbuf_load_module
2561 2001-01-22 Havoc Pennington <hp@redhat.com>
2563 * Makefile.am: Add built marshaller files to support
2564 GdkPixbufLoader signals
2566 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
2567 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
2568 module location, rather than acting as a fallback, because we are
2569 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
2571 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
2573 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
2574 from gtk, and add error to close(), because stop_load may do
2575 parsing of the image.
2577 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
2579 * io-*.c: make individual operations static, and add fill_vtable
2580 functions which are exported. Fix the collection of type warnings
2581 that surfaced, including a number of functions that didn't
2582 properly take a GError and some that weren't
2583 const-correct. Involved adding error handling for a few loaders.
2585 * gdk-pixbuf-io.h: Add error reporting to stop_load function
2587 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
2588 a function that fills in the GdkPixbufModule vtable, instead of
2589 looking up all the image functions individually; this means we
2590 can get type safety within modules for the loader functions.
2591 Also it means you don't have to keep the statically compiled and
2592 GModule versions in sync.
2594 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
2596 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
2598 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
2600 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
2603 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
2605 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
2608 2001-01-20 John Harper <jsh@eazel.com>
2610 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
2611 collision between Xlib's RdBitF.c and io-tiff.c
2613 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
2616 [ merged from stable gdk-pixbuf module. Untested, but it
2617 compiles, and works fine in the stable module ]
2619 2001-01-18 Tor Lillqvist <tml@iki.fi>
2621 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
2622 g_win32_get_package_installation_subdirectory() function. No need
2623 to include windows.h.
2624 (gtk_win32_get_installation_directory): Remove this then.
2626 2001-01-01 Havoc Pennington <hp@redhat.com>
2628 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
2629 @LIBTOOL_EXPORT_OPTIONS@
2631 2000-12-30 Tor Lillqvist <tml@iki.fi>
2633 * gdk_pixbuf.def: Update.
2635 2000-12-16 Havoc Pennington <hp@pobox.com>
2637 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
2638 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
2639 (gdk_pixbuf_frame_copy): new function
2640 (gdk_pixbuf_frame_free): new function
2641 (gdk_pixbuf_frame_get_type): new function
2642 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
2644 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
2646 * Makefile.am: Add -avoid-version for all modules.
2648 2000-11-13 Havoc Pennington <hp@redhat.com>
2650 * io-png.c (png_simple_error_callback): fix error message to not
2651 say "save" since it's used for loading
2653 2000-11-11 Hans Breuer <Hans@Breuer.Org>
2655 * gdk-pixbuf-io.c : Fix all function prototype macros for self
2656 contained image handlers (!USE_G_MODULE). Files to save should
2657 be opened in binary mode, fopen(s, "wb").
2659 * io-xpm.c : added HAVE_UNISTD_H condition
2661 2000-11-11 Tor Lillqvist <tml@iki.fi>
2663 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
2665 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
2666 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
2667 mktemp() and open()).
2669 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
2671 2000-11-01 Havoc Pennington <hp@pobox.com>
2673 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
2674 a pixbuf pointing to a subregion of another pixbuf.
2676 2000-10-16 Tor Lillqvist <tml@iki.fi>
2678 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
2680 2000-10-16 Havoc Pennington <hp@redhat.com>
2682 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
2683 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
2684 add error reporting here also
2686 * make-inline-pixbuf.c (main): use GError
2688 * io-xpm.c: include unistd.h
2690 * gdk-pixbuf-util.c: include string.h
2692 * io-*.c: add error reporting
2694 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
2697 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
2699 * gdk-pixbuf-io.h: Add GError** to load_increment and load
2702 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
2703 a G_FILE_ERROR if we fail to write or close the file.
2705 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
2706 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
2707 the GError naming rules. Add GError** to load functions.
2709 2000-10-06 Havoc Pennington <hp@redhat.com>
2711 * gdk-pixbuf.h: add GdkPixbufAlphaMode
2713 2000-10-06 Havoc Pennington <hp@redhat.com>

2745 all error conditions gracefully.
2747 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
2749 * gdk-pixbuf/io-pnm.c: Rewrote.
2751 2000-09-09 Federico Mena Quintero <federico@helixcode.com>
2753 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute

2771 2000-07-21 Larry Ewing <lewing@helixcode.com>
2773 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
2774 xpm at least supports the progressive interface like the one in
2775 io-tiff.c. This should be reimplemented as an actual progressive
2778 2000-07-19 Jonathan Blandford <jrb@redhat.com>
2780 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
2781 make it look better.
2782 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
2783 meeks to handle errors better.
2785 2000-10-07 Tor Lillqvist <tml@iki.fi>
2788 * pixbufloader_jpeg.def
2789 * pixbufloader_png.def: Add new entry points.
2791 * makefile.mingw.in: Use libintl.
2793 2000-10-06 Havoc Pennington <hp@redhat.com>
2795 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
2796 consistent with gdk_pixbuf_loader_new_with_type().
2797 Return runtime error if a module is missing.
2799 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
2801 2000-10-05 Havoc Pennington <hp@redhat.com>
2803 Pixbuf saving, patch from David Welton.
2805 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
2806 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
2808 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf
2810 * io-png.c (gdk_pixbuf__png_image_save): PNG save routine.
2812 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): JPEG save routine.
2814 * gdk-pixbuf-io.c (gdk_pixbuf_save):
2815 (gdk_pixbuf_savev): Implement pixbuf saving routines
2817 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
2820 * gdk-pixbuf.h: Add public save routines; add pixbuf error
2823 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
2825 2000-10-05 Dan Winship <danw@helixcode.com>
2827 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
2828 all three of these files are the JPEG image loader. (From
2831 2000-10-03 Tor Lillqvist <tml@iki.fi>
2833 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
2834 gdk-pixbuf's version number in the rule for makefile.mingw itself.
2836 * gdk_pixbuf.def: Add new entry points.
2838 2000-09-26 Havoc Pennington <hp@redhat.com>
2840 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
2841 function here, instead of putting it in a private GTK+ file.
2843 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
2844 enum here for the known formats of inlined pixbufs.
2845 Also, #define our file magic here.
2847 2000-06-23 Havoc Pennington <hp@redhat.com>
2849 * make-inline-pixbuf.c: Small program that creates C variable
2850 declarations of inline pixbuf data. This can be read
2851 by gdk_pixbuf_new_from_inline.
2853 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
2854 inline pixbuf data and create a pixbuf from it.
2856 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
2858 2000-09-07 Tor Lillqvist <tml@iki.fi>
2860 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
2863 2000-08-12 Tor Lillqvist <tml@iki.fi>
2865 * gdk_pixbuf.def: Add missing entry point.
2867 2000-08-10 Havoc Pennington <hp@redhat.com>
2869 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
2870 (s/pixbuf_/pixbufloader_)
2872 2000-08-02 Tor Lillqvist <tml@iki.fi>
2878 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
2880 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
2881 one. Fix names of DLLs to have '-' instead of '_'.
2883 2000-07-31 Elliot Lee <sopwith@redhat.com>
2884 * io-wbmp.c: Some bug fixes - now tested to work.
2886 2000-07-27 Elliot Lee <sopwith@redhat.com>
2888 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
2889 gdk_pixbuf_get_named_module() function to facilitate above change
2890 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
2891 Implement loader for WBMP format.
2892 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
2894 2000-07-23 Tor Lillqvist <tml@iki.fi>
2899 * pixops/makefile.mingw.in
2900 * pixbuf_*.def: New files.
2903 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
2905 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
2906 New function, to get the GTK+ installation directory from
2907 the Windows Registry, where the installation program
2908 for whatever software includes GTK+ has stored it.
2910 Used to avoid having hardcoding the directory where to look for
2911 loaders. This function is needed by gtk, too, so it should
2912 really be just in one place. Maybe a small static library
2913 one level up from here?
2915 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
2916 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
2917 Open file in binary mode. This *is* standard C. (No-op on Unix,
2920 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
2922 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
2923 mktemp() and open().
2924 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
2926 * pixops/*.S: The Gas from mingw32 doesn't like the .type
2927 pseudo-op. Conditionalise on __MINGW32__, but probably
2928 should conditionalise on Gas version instead? Or could we
2929 do without .type on all systems?
2931 * pixops/timescale.c: Use g_get_current_time()
2932 instead of gettimeofday().
2934 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
2936 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
2938 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
2940 * gdk-pixbuf.c: Add <string.h> include.
2942 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
2944 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
2945 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
2946 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
2947 use g_object_new() instead of g_type_create_instance() which
2948 is a private function for fundamental type implementations.
2950 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
2952 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
2953 soname scheme for gdk-pixbuf.
2955 2000-06-21 Havoc Pennington <hp@pobox.com>
2957 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
2958 (i.e. derivation is not allowed, and there are no virtual methods
2960 (gdk_pixbuf_preinit): Call g_type_init() here.
2961 (gdk_pixbuf_init): Add a user-friendly init function, for users
2962 of standalone gdk-pixbuf
2964 * gdk-pixbuf-animation.c: Convert to GObject, in the same
2965 way GdkPixbufAnimation was done.
2967 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
2968 gdk_pixbuf_finalize() from API, since these are broken and don't
2969 make sense with new GObject stuff.
2971 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
2973 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
2974 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
2977 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
2979 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
2980 so I needed something to warm my thighs. Running plain infinite
2981 loops on your laptop to make it hot is not very much fun. A demo
2982 of the gdk-pixbuf scaling functions is way better, and looks
2985 * configure.in (AC_OUTPUT): Added the demo Makefile.
2987 * Makefile.am (SUBDIRS): Added the demo directory.
2989 2000-06-09 Larry Ewing <lewing@helixcode.com>
2991 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
2992 setjmp for the png error handler. It seems setting the error
2993 handling functions does not avoid the jump, and so not calling
2994 setjmp was causing the incremental loader to jump into lala land.
2995 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
2996 not sure this one is actually required but the docs say it must be
2997 set for every call to a png_* function.
2998 Also changed the comment to reflect the fact that setting the
2999 error handlers does _not_ avoid the longjmp.
3001 2000-06-06 Larry Ewing <lewing@helixcode.com>
3003 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
3004 take frame offest into account when trying to calculate the
3005 animation bbox. Also set the width to the width not the height.
3006 (gdk_pixbuf_loader_animation_done): cycle over the frames to
3007 calculate bbox because now we finally have all the offset
3008 information for each frame.
3010 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
3012 * configure.in: add some gtk parameters to the
3013 GDK_PIXBUF_LIBÃ�²S and GDK_PIXBUG_INCLUDEDIR vars. One more
3014 fight in my crusade for strange prefix compile...
3016 2000-05-30 Not Zed <NotZed@HelixCode.com>
3018 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
3019 Initialise the error handler exit routine to our own. Note this
3020 means that every function that accesses the jpeg lib on this
3021 object MUST do a setjmp.
3022 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
3023 lib for handling fatal error.
3024 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
3025 your applications dont quit if there's a jpeg error!
3027 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
3029 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
3030 from Frank de Lange <frank@unternet.org>.
3032 2000-05-09 Darin Adler <darin@eazel.com>
3034 * gdk-pixbuf/test-gdk-pixbuf.c:
3035 Fixed includes to get rid of accidental GNOME dependency.
3037 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
3038 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
3040 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
3042 * configure.in: Bumped version number to 0.8.0.
3044 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
3045 file was not being distributed.
3047 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
3049 2000-05-09 Darin Adler <darin@eazel.com>
3051 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
3052 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
3053 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
3054 formats to 32-bit formats to re-use the high bits of the color values
3055 so that white maps to full white.
3057 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
3059 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
3060 detailed information about the structure and algorithms
3061 of pixops so people can fix it instead of breaking it.
3063 2000-05-04 Darin Adler <darin@eazel.com>
3065 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
3066 (composite_pixel), (composite_line):
3067 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
3068 Now that Owen explained the algorithm, I think I implemented it
3069 right for the cases where the destination pixbuf is not opaque.
3070 The test does seem to confirm it.
3072 2000-05-04 Darin Adler <darin@eazel.com>
3074 * gdk-pixbuf/.cvsignore:
3075 * gdk-pixbuf/Makefile.am:
3076 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
3077 (load_pixel), (simple_composite_test_one),
3078 (simple_composite_test_one_type), (simple_composite_test), (main):
3079 Added some tests of composite to highlight problems in the old
3080 implementation. These tests run without any user interaction.
3081 Just do "make check".
3083 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
3084 (composite_pixel), (composite_line): Fix composite to do a textbook
3085 "A over B" composite. This was clearly the intent, and it was easy
3086 to fix the code to do it. (Note to those that read my earlier tries
3087 at a patch; this version fixes typos that were present in all
3088 my patch attempts. I checked the final version by adding more tests.)
3090 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
3092 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
3093 offset y coordinate accordining to render_y0.
3095 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
3098 2000-04-22 James Henstridge <james@daa.com.au>
3100 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
3101 package to the devel package. The only file installed in bin is
3102 gdk-pixbuf-config, which belongs in -devel. This should allow having
3103 multiple versions of the main gdk-pixbuf package installed.
3105 2000-04-17 Karl Eichwalder <ke@suse.de>
3107 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
3108 Reported by Jens Finke.
3110 2000-04-14 Tomasz KÃ�³opczko <kloczek@pld.org.pl>
3112 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
3113 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
3115 2000-04-13 James Henstridge <james@daa.com.au>
3117 * configure.in: when performing the configure check to see if
3118 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
3119 rather than the other way round. Also, call AC_MSG_RESULT in the
3120 even that dynamic modules were not supported.
3122 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
3124 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
3125 hook to the last unref operation.
3127 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
3128 function to set the last unref handler for a pixbuf.
3129 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
3130 It calls the pixbuf's destroy notification function and frees the
3131 GdkPixbuf structure itself.
3132 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
3135 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
3136 for the last unref handler and its user data.
3138 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
3139 g_new0() to allocate the pixbuf.
3141 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
3142 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
3143 was not specifying the `frame' argument.
3145 * gdk-pixbuf/gdk-pixbuf-animation.c
3146 (gdk_pixbuf_animation_get_width): Fixed docstring.
3147 (gdk_pixbuf_animation_get_height): Likewise.
3148 (gdk_pixbuf_animation_get_num_frames): Likewise.
3149 (gdk_pixbuf_animation_get_frames): Likewise.
3151 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
3154 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
3156 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
3158 * doc/tmpl/refcounting.sgml: Updated with the information about
3159 the last unref handler.
3161 * doc/tmpl/*.sgml: Markup tweaks.
3163 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
3164 update the libtool version number for libgnomecanvaspixbuf as
3166 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
3167 as well, or the old ones won't work with the new stuff. Also,
3168 renamed the modules as follows.
3170 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
3171 modules are called "libpixbufloader-<format>.so" instead of
3172 "libpixbuf-<format>.so". They needed renaming so that the new
3173 loaders won't overwrite the old ones; even with the versioning
3174 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
3177 2000-04-12 Paolo Molaro <lupus@debian.org>
3179 * .cvsignore, src/.cvsignore: shut up cvs.
3181 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
3183 Most of this patch is based on a patch by Havoc Pennington
3184 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
3185 remove the libart dependency.
3187 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
3188 (GdkColorspace): New enum that for now only contains
3190 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
3191 notification function.
3192 (GdkInterpType): New num with interpolation types.
3194 * *.[ch]: Replace the libart stuff with our own stuff.
3196 * pixops/*.[ch]: Likewise.
3198 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
3199 declarations of the GdkPixbuf structures.
3201 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
3203 (gdk_pixbuf_get_format): Constify.
3204 (gdk_pixbuf_get_n_channels): Constify.
3205 (gdk_pixbuf_get_has_alpha): Constify.
3206 (gdk_pixbuf_get_bits_per_sample): Constify.
3207 (gdk_pixbuf_get_pixels): Constify.
3208 (gdk_pixbuf_get_width): Constify.
3209 (gdk_pixbuf_get_height): Constify.
3210 (gdk_pixbuf_get_rowstride): Constify.
3212 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
3215 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
3216 bits_per_sample argument; currently only 8 bits per sample are

3732 * gdk-pixbuf/io-gif.c (image_begin_load): ditto
3734 2000-01-05 Owen Taylor <otaylor@redhat.com>
3736 * gdk-pixbuf/pixops/README: Added a README with a TODO
3737 and some explainations of the algorithms.
3739 * gdk-pixbuf/testpixbuf-scale.c: Set a background pixmap of None
3740 to reduce flashing when resizing.
3742 2000-01-05 Owen Taylor <otaylor@redhat.com>
3744 * gdk-pixbuf/pixops/: Directory full of pixel data scaling
3745 code that will eventually migrate into libart.
3747 * configure.in acconfig.h: Add checks for MMX compiler support
3749 * gdk-pixbuf/gdk-pixbuf.h gdk-pixbuf/gdk-pixbuf-scale.c:
3750 Nice wrapper routines for the code in pixops that operate
3751 on pixbufs instead of raw data.
3753 * gdk-pixbuf/testpixbuf-scale: Test program for scaling
3756 2000-01-05 Jonathan Blandford <jrb@redhat.com>
3758 * doc/tmpl/animation.sgml: Documentation changes.
3760 2000-01-01 Federico Mena Quintero <federico@helixcode.com>
3762 * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
3763 counting to animations. A web browser may want to share a single
3764 copy of an animated GIF if it appears multiple times in a web
3767 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
3768 animation functions here.
3769 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
3770 animation if the loader does not support multiframe loading and
3771 the single-frame load returned NULL. Check that the filename is
3772 not NULL. Updated inline documentation.
3773 (gdk_pixbuf_animation_ref): New function.
3774 (gdk_pixbuf_animation_unref): New function.
3775 Removed gdk_pixbuf_animation_destroy() in favor of reference
3778 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
3779 Prettified. Made ref_count assertion more paranoid. Check that
3780 the filename is not NULL.
3781 (gdk_pixbuf_get_module): Use guchar * and guint for buffer and
3783 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
3786 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
3787 with a reference count of 1.
3789 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
3790 gdk-pixbuf-animation.c.
3792 * doc/tmpl/animation.sgml: Populated. It is still missing a
3793 description of the overlay modes.
3795 * doc/gdk-pixbuf-sections.txt: Added the animation section. Moved
3796 the canvas item section to the end, as it will be moved later to
3799 * doc/gdk-pixbuf.sgml: Added the animation section.
3801 * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
3803 1999-12-26 Peter Teichman <pat@gnu.org>
3805 * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add
3806 $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker.
3807 This closes bug #4676.
3809 1999-12-23 Havoc Pennington <hp@pobox.com>
3811 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
3812 set to NULL here (specifically context->animation) was not being
3813 set to NULL. use g_new0() to alloc the struct.
3815 1999-12-20 Jonathan Blandford <jrb@redhat.com>
3817 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
3818 correctly. Progressive loading needs some work, but that all
3819 needs doing from the gdk-pixbuf-loader end, not here.
3821 1999-12-17 Jonathan Blandford <jrb@redhat.com>
3823 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
3824 moved the file here. It seems natural to put this function here,
3825 as that's where the gdk_pixbuf_new_from_file function is, but it's
3826 still a little convoluted. The source files might be played with
3829 1999-12-14 Jonathan Blandford <jrb@redhat.com>
3831 * gdk-pixbuf/gdk-pixbuf-loader.c
3832 (gdk_pixbuf_loader_get_animation): Gets the animation from the
3835 1999-12-16 Federico Mena Quintero <federico@redhat.com>
3837 * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
3838 before using the GdkPixbuf rendering functions. Thanks to Joe
3839 Shaw <joe@off.net> for pointing this out.
3841 1999-12-13 Federico Mena Quintero <federico@redhat.com>
3843 * gdk-pixbuf/gnome-canvas-pixbuf.c
3844 (gnome_canvas_pixbuf_class_init): Renamed arguments to
3845 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
3846 consistency with the new canvas.
3847 (PixbufPrivate): Do the same renaming in the structure fields, for
3850 * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.
3852 1999-12-12 Federico Mena Quintero <federico@redhat.com>
3854 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
3855 conditional to see whether to link $(GNOME_LIBS) or not.
3857 1999-12-10 Jonathan Blandford <jrb@redhat.com>
3859 * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API.
3861 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
3862 make a warning go away.
3864 * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations.
3866 * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for
3869 1999-12-09 Michael Zucchi <zucchi@zedzone.mmc.com.au>
3871 * gdk-pixbuf/gdk-pixbuf.h: Enable gdk_pixbuf_get_from_drawable()
3874 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
3875 Filled in body of function.
3876 (rgbconvert): Added GdkColormap parameter, and to all conversion
3878 (convert_real_slow): New function - should convert ANY visual/data
3879 format properly, but it aint fast. Used as a fallback when an
3880 optimised routine wont match.
3881 (rgbconvert): Do very specific tests on the data format to verify
3882 properly if the optimised version will do, otherwise use the
3883 fallback function for all other data formats.
3885 * gdk-pixbuf/Makefile.am: Re-enabled building of
3886 textpixbuf-drawable.
3888 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
3889 gdk_pixbuf_get_from_drawable().
3891 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
3893 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
3894 bug on two occasions.
3895 * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu
3896 function to the generic glib one.
3898 1999-12-08 Federico Mena Quintero <federico@redhat.com>
3900 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
3901 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
3902 checks and API definition. The body needs filling in and it needs
3903 to do the Right Thing(tm) for pixmaps plus the given colormap and
3904 windows and their own colormaps.
3906 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
3907 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
3909 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
3911 * doc/tmpl/from-drawables.sgml: Populated.
3913 * doc/gdk-pixbuf.sgml: Added the from-drawables section.
3915 * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml.
3917 * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs
3920 1999-12-07 Federico Mena Quintero <federico@redhat.com>
3922 * doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about
3923 reference counting for GdkPixbuf structures.
3925 1999-12-07 Martin Baulig <martin@home-of-linux.org>
3927 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
3928 include $(GNOME_LIBS) here.
3930 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
3932 Added missing "include <string.h>" to:
3933 * gdk-pixbuf/io-ras.c
3934 * gdk-pixbuf/io-bmp.c
3935 * gdk-pixbuf/io-ico.c
3937 1999-12-06 Federico Mena Quintero <federico@redhat.com>
3939 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
3942 1999-12-05 Federico Mena Quintero <federico@redhat.com>
3944 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
3945 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
3946 want, send me a patch to do the conditional stuff properly.
3947 Otherwise, please read the GNOME Programming Guidelines,
3948 especially the "CVS policies" section.
3950 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
3952 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
3954 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
3956 * gdk-pixbuf/io-ico.c: Bug in palet-size
3959 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
3961 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
3962 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
3964 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
3966 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
3969 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
3970 (Windows Cursor files). These are identical to .ICO files,
3971 except for the signature and 2 extra fields for the hotspot.
3973 1999-12-03 Federico Mena Quintero <federico@redhat.com>
3975 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):
3976 Removed unused variable `item'.
3978 1999-12-03 Jonathan Blandford <jrb@redhat.com>
3980 * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
3981 explain this function better.
3983 1999-12-02 Federico Mena Quintero <federico@redhat.com>
3985 Source files moved from src/ to gdk-pixbuf/, to be consistent with
3988 * doc/Makefile.am: Modified for the new source directory.
3990 * configure.in: Likewise.
3992 * Makefile.am: Likewise.
3994 * autogen.sh: Likewise.
3996 * gdk-pixbuf/Makefile.am: Likewise.
3998 1999-12-02 Federico Mena Quintero <federico@redhat.com>
4000 * src/testpixbuf.c: #include <config.h>, and fix includes.
4002 * src/testpixbuf-drawable.c: #include <config.h>, and fix includes.

4012 * src/io-png.c: Fix includes.
4014 * src/io-ico.c: Fix includes, and do not include more stuff than needed.
4016 * src/io-gif.c: Fix includes, and do not include more stuff than needed.

4026 * src/gdk-pixbuf-render.c: Fix includes.
4028 * src/gdk-pixbuf-io.h: Fix includes.
4030 * src/gdk-pixbuf-drawable.c: Fix includes.
4032 * src/gdk-pixbuf-drawable.h: Use angle brackets for the gdk-pixbuf
4035 * src/gdk-pixbuf-data.c: Fix includes.
4037 * src/gdk-pixbuf-loader.c: #include <config.h>
4039 * src/gdk-pixbuf-loader.h: Use angle brackets for the gdk-pixbuf
4042 * src/Makefile.am: Commented out the gdk-pixbuf-drawable stuff,
4043 since it is not finished.
4045 * src/gdk-pixbuf.h: Removed unused transformation prototypes.
4047 * src/gdk-pixbuf-util.c: New file with utility and convenience
4048 functions for pixbufs.
4050 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c.
4052 * doc/gdk-pixbuf-sections.txt: Added section for utility functions.
4054 * doc/Makefile.am (tmpl_sources): Added tmpl/util.sgml.
4056 * doc/gdk-pixbuf.sgml: Added the utilities section.
4058 * doc/tmpl/util.sgml: Documentation for the utility functions.
4060 1999-11-29 Owen Taylor <otaylor@redhat.com>
4062 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
4063 Keep the mask around until after we draw ... since
4064 the GC changes aren't flushed to the X server until we
4065 draw, destroying it before that may result in BadPixmap
4068 1999-11-30 Havoc Pennington <hp@pobox.com>
4070 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
4072 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
4074 1999-11-29 Federico Mena Quintero <federico@redhat.com>
4076 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
4077 should be made conditional, not blindly commented out.
4079 1999-11-29 Jonathan Blandford <jrb@redhat.com>
4081 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
4082 handle .ico files. Cool.
4084 1999-11-24 Jonathan Blandford <jrb@redhat.com>
4086 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
4089 1999-11-24 James Henstridge <james@daa.com.au>
4091 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
4092 top builddir rather than src. This still builds fine, and does not
4093 get gtk-doc into an infinite loop when trying to find all the source
4096 1999-11-23 Jonathan Blandford <jrb@redhat.com>
4098 * Removed #PRAGMA } from headers. Also, make compile if you don't
4099 have it installed, already.
4101 1999-11-22 Federico Mena Quintero <federico@redhat.com>
4103 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
4104 temporary buffer to the size of the interesction of the bounding
4105 box and the expose area, not the whole expose area. This speeds
4108 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
4109 not paint black on the mask, since we already cleared it in a
4110 single gdk_draw_rectangle() operation.
4112 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
4114 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
4116 1999-11-22 Havoc Pennington <hp@pobox.com>
4118 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
4119 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
4120 dependencies to LIBADD variables for loadable modules. Necessary
4121 for a Java dynamic loading thing to be able to figure it out.
4123 1999-11-22 Havoc Pennington <hp@pobox.com>
4125 * src/io-png.c (image_load_increment): Call the update_area
4126 callback depending on the number of rows loaded in this increment.
4128 * src/testpixbuf.c (main): slow down the progressive load demo
4130 1999-11-16 Havoc Pennington <hp@pobox.com>
4132 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
4134 1999-11-22 Jonathan Blandford <jrb@redhat.com>
4136 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
4137 for srcdir != buildir != . Beats me why; I can't figure it out.
4138 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
4140 1999-11-21 Jonathan Blandford <jrb@redhat.com>
4142 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
4143 <arjan@fenrus.demon.nl>
4145 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
4147 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
4148 Rework/reorder of the code. Each case has been separated into
4149 another function; its big but it should be quick.
4150 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
4151 opaque alpha information. Not all depths/formats have been
4152 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
4154 1999-11-17 Larry Ewing <lewing@gimp.org>
4156 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
4157 implement the bounds method correctly.
4158 (compute_viewport_affine): compute the affine need to fit the
4159 image within the viewport given by the args.
4160 (compute_render_affine): call compute_viewport_affine.
4162 1999-11-16 Havoc Pennington <hp@pobox.com>
4164 * src/gdk-pixbuf-drawable.h: Use includes from the current
4165 directory, not the system directory.
4167 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
4169 * src/testpixbuf-drawable.c: use includes from the current directory
4170 rather then from the system include directory as gdk-pixbuf
4171 includes are not yet installed when this is compiled.
4173 1999-11-13 Cody Russell <bratsche@dfw.net>
4174 * src/testpixbuf-drawable.c: Added a test program for drawable
4177 * src/Makefile.am: Build testpixbuf-drawable.
4179 1999-11-12 Cody Russell <bratsche@dfw.net>
4181 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.
4183 1999-11-10 Federico Mena Quintero <federico@redhat.com>
4185 * doc/tmpl/gdk-pixbuf-loader.sgml: Populated.
4187 * doc/gdk-pixbuf.signals: Put in the real names of signal
4190 * src/gdk-pixbuf-loader.c: Improved documentation comments.
4192 1999-11-10 Jonathan Blandford <jrb@redhat.com>
4194 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
4197 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
4198 correctly. Patch from Arjan to do so.
4200 1999-11-10 Michael Fulbright <drmike@redhat.com>
4202 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
4205 * src/testpixbuf.c: Added final queued draw when done loading image.
4207 1999-11-10 Jonathan Blandford <jrb@redhat.com>
4209 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
4212 1999-11-10 Federico Mena Quintero <federico@redhat.com>
4214 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
4217 1999-11-09 Federico Mena Quintero <federico@redhat.com>
4219 * src/io-png.c: Fixed some incompatible pointer initializations.
4221 * src/io-jpeg.c (image_load_increment): Remove unused variable.
4223 1999-11-09 Michael Fulbright <drmike@redhat.com>
4225 * src/testpixbuf.c: Fixed it to use timeout to read from file
4226 for progressive loading. Set TBF_KBPS=n, where n is the number of
4227 kilobytes/second to simulate in downloading. n has to be an integer.
4229 * src/io-jpeg.c: Slight cosmetic cleanup.
4231 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
4232 PBM loading has a similar problem and will address tomorrow.
4234 1999-11-09 Havoc Pennington <hp@pobox.com>
4236 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
4237 gdk-pixbuf-drawable stuff.
4239 1999-11-09 Federico Mena Quintero <federico@redhat.com>
4241 * configure.in: Bumped version number to 0.4.
4243 1999-11-09 Michael Fulbright <drmike@redhat.com>
4245 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
4246 all types of PNM files now.
4248 * src/io-jpeg.c (image_load_increment): Figured out problem with
4249 loading Progressive JPEG's progressively (say that 10 times fast).
4250 Currently for Progressive JPEG's the entire image is loaded before
4251 it is displayed. libjpeg supports a fancier mechanism which I may
4254 With these changes all JPEG formats appear to load properly for me.
4256 1999-11-08 Jonathan Blandford <jrb@redhat.com>
4258 * src/io-ras.c (image_load_increment): Final patch from Arjan.
4259 Seems to do progressive loading.
4261 1999-11-08 Michael Fulbright <drmike@redhat.com>
4263 * src/io-pnm.c image_load (): Fixed so we do not create a separate
4264 pixel buffer when reading in image - we reuse the pixel data in
4265 the GdkPixbuf structure instead.
4267 1999-11-08 Michael Fulbright <drmike@redhat.com>
4269 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
4270 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
4271 I can't seem to find a utility to convert into this format.
4272 Next is to add progressive loading support for the PNM format.
4274 1999-11-07 Federico Mena Quintero <federico@redhat.com>
4276 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
4277 of the width, height, x, and y setting and pixels arguments.
4279 1999-11-05 Jonathan Blandford <jrb@redhat.com>
4281 * src/io-ras.c (image_load): third patch. Now it seems to load.
4283 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
4284 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
4286 * src/io-ras.c (image_load): new file from Arjan van de Ven
4287 <arjan@fenrus.demon.nl> to begin the ras loader.
4289 1999-11-05 Federico Mena Quintero <federico@redhat.com>
4291 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
4292 for internal use only.

4331 separately. Fix GNOME_LIBS to be correct in "no gnome installed
4334 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
4337 Patch untested in the inside-gnome-libs case, I need to commit
4338 then check out to the gnome-libs I'm using.
4340 1999-11-04 Michael Fulbright <drmike@redhat.com>
4342 * src/io-jpeg.c (image_begin_load): Add update_func callback.
4343 * src/io-jpeg.c (image_load_increment): Call updated callback when
4344 new graphic data decoded.
4346 1999-11-04 Jonathan Blandford <jrb@redhat.com>

4371 1999-11-03 Federico Mena Quintero <federico@redhat.com>
4373 * configure.in: Removed libgif stuff now that we do not depend on it.
4374 Added the necessary cruft for gtk-doc.
4376 * src/Makefile.am: Unconditionally build the GIF loader.
4378 1999-11-03 Jonathan Blandford <jrb@redhat.com>
4380 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.

4386 1999-11-03 Michael Fulbright <drmike@redhat.com>
4388 * src/io-jpeg.c (image_load_increment): Further removal of
4389 bugginess in local buffering code. Handles grayscale jpegs
4392 * src/io-jpeg.c (image_load_stop): Was freeing local context
4393 for jpeg library before calling jpeg_decompres_finish ().
4395 1999-11-03 Jonathan Blandford <jrb@redhat.com>
4397 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
4399 (gif_get_lzw): set the transparency to the right val.
4401 1999-11-03 Federico Mena Quintero <federico@redhat.com>
4403 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
4404 Initiailize the x and y fields.
4405 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
4406 (PixbufPrivate): Renamed need_size_update to need_xform_update.
4407 (recompute_bounding_box): Do not use temporary values.
4409 1999-11-03 Jonathan Blandford <jrb@redhat.com>

4419 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
4420 render_affine calculation for x,y offsets.
4421 (gnome_canvas_pixbuf_set_arg): add x,y args.
4422 (gnome_canvas_pixbuf_get_arg): add x,y args.
4423 (recompute_bounding_box): simply code using ArtDrect and the
4424 render_affine. Removed compute_xform_vectors as it was no longer
4427 1999-11-03 Federico Mena Quintero <federico@redhat.com>
4429 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
4430 doofus. Return a distance, not a boolean, for opaque images.
4432 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
4433 rounding of bounding box coordinates.
4434 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
4435 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
4437 1999-11-03 Jonathan Blandford <jrb@redhat.com>
4439 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
4441 1999-11-03 Michael Fulbright <drmike@redhat.com>
4443 * src/io-jpg.c (image_load_increment): Fixed code which moved
4444 buffer around as new data comes in to work properly. JPEG progressive
4445 loading should be working now except for grayscale JPEG's, which I
4446 will look into next.
4448 1999-11-03 <sopwith@redhat.com>
4449 * src/testpixbuf.c: A GtkFunction needs to return a value for
4450 deterministic behaviour. Also put dot printing back in.
4452 1999-11-03 <jrb@redhat.com>
4454 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
4457 1999-11-02 Cody Russell <bratsche@dfw.net>
4458 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
4459 if part of the requested image is offscreen, rather than clipping
4462 1999-11-02 Jonathan Blandford <jrb@redhat.com>
4464 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
4465 for interlacing and progressive loading.
4467 1999-11-02 Cody Russell <bratsche@dfw.net>
4468 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
4469 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
4471 1999-11-02 Jonathan Blandford <jrb@redhat.com>
4473 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
4474 It's a little slow though. )-:
4476 1999-11-02 Elliot Lee <sopwith@redhat.com>
4477 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the
4478 arguments to the write/load_increment operations const-correct.
4480 1999-11-02 Federico Mena Quintero <federico@redhat.com>
4482 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
4483 Implemented the ::point() method. We do a simple containment test
4484 instead of a full distance calculation since the canvas is going
4485 to change to that scheme, anyways.
4487 1999-11-02 Elliot Lee <sopwith@redhat.com>
4489 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size
4490 of the chunks that are read from the input file.
4492 1999-11-02 Larry Ewing <lewing@gimp.org>
4494 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
4496 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
4499 1999-11-02 Federico Mena Quintero <federico@redhat.com>
4501 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
4502 affine computation code from ::draw() to here, since it is needed
4503 by ::point() as well.
4505 1999-11-02 Elliot Lee <sopwith@redhat.com>
4507 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
4508 three functions, and eliminate duplication of code from write()
4509 and close(). Also fix bug where the 128-byte header was being
4512 1999-11-01 Federico Mena Quintero <federico@redhat.com>
4513 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
4514 bounding box computation.
4516 1999-11-01 Federico Mena Quintero <federico@redhat.com>
4518 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
4519 Drawing affines seem to work. Bounding box is fubared. ::point()
4520 is not implemented. This is a work in progress.
4522 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
4525 * configure.in: Sigh. We need to link in libgnomeui for the
4526 canvas stuff. This mess will disappear when gdk-pixbuf gets
4527 folded into gnome-libs.
4529 1999-10-30 Jonathan Blandford <jrb@redhat.com>
4531 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
4532 the right size, at a minimum, even if the image is squished and
4534 (ReadImage): lets get the offset right. This will let transparent
4537 1999-10-29 Michael Fulbright <drmike@redhat.com>
4539 * src/io-jpeg.c: image_load_increment(): Fixed bug when
4540 image width was not a multiple of 4 - always use the
4541 gdk_pixbuf rowstride to increment pointers!
4543 1999-10-29 Michael Fulbright <drmike@redhat.com>
4545 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
4546 Currently does not handle either progressive jpeg files (jpeg
4547 files with multiple scans at different quality settings), but
4548 I plan on adding this support soon. These are fairly rare in
4549 my experience, so it shouldn't slow people down too much.
4550 Grayscale jpegs also don't work but that should be easy to fix.
4552 1999-10-29 Michael Fulbright <drmike@redhat.com>
4554 * src/testpixbuf.c: Added title to windows so you can identify
4555 progressive and file windows.
4557 1999-10-29 Michael Fulbright <drmike@redhat.com>
4559 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
4560 load the image handler when we determine the image type.
4562 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
4563 previously static function load_image_handler () to
4564 a public function gdk_pixbuf_load_module (). It is needed in
4565 gdk-pixbuf-loader.c to load image handler modules. This function
4566 is different from gdk_pixbuf_get_module (), which only returns
4567 a reference to the required handler, because it actually loads
4568 the handler into memory. Both actions should possibly be combined
4569 in a convenience function since one w/o the other doesn't seem to
4572 1999-10-28 Jonathan Blandford <jrb@redhat.com>
4574 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
4577 1999-10-28 Federico Mena Quintero <federico@redhat.com>
4579 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
4580 function to render a portion of a pixbuf to a drawable. Ignores
4581 alpha information and takes in a GC.
4582 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
4583 portion of a pixbuf to a drawable. It automatically creates a GC
4584 and a clipping mask for alpha pixbufs.
4586 1999-10-28 Jonathan Blandford <jrb@redhat.com>
4588 * src/gdk-pixbuf.h: turned convenience macros into convenience
4589 functions so some error checking could be added.
4591 * src/io-tiff.c (image_load_increment): started work on the tiff
4592 non-incremental loader.
4593 (image_begin_load): Finished the incremental loader.
4595 * src/io-gif.c (image_load_increment): started work on the gif

4600 1999-10-27 Federico Mena Quintero <federico@redhat.com>
4602 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
4603 function to threshold a pixbuf's alpha channel into a bitmap.
4605 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
4606 contemplate future extensions to ArtPixBuf's formats.
4608 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
4610 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
4611 macros to fetch the ArtPixBuf's fields.
4613 1999-10-27 Havoc Pennington <hp@pobox.com>
4615 * src/testpixbuf.c (main): Display the progressive load
4617 * src/io-png.c (setup_png_transformations): Break transformation
4618 code into separate function
4619 (png_info_callback): Use setup_png_transformations
4621 1999-10-27 Havoc Pennington <hp@pobox.com>
4623 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
4624 properly whether the XPM module has already been loaded
4625 (gdk_pixbuf_new_from_file): Check properly if loader module
4626 was already loaded (was checking if load symbol was present
4627 in order to decide whether to re-load; should check module !=
4628 NULL, then load != NULL)
4629 (image_handler_load): Check in present working directory,
4630 makes it easier to debug for now
4631 (file_formats): This array initializer was seriously on crack,
4632 was assigning a function pointer to a GModule*
4634 * src/testpixbuf.c (main): Change type of pixbuf_loader to
4637 1999-10-27 Havoc Pennington <hp@pobox.com>

4652 class destroy function.
4653 (gdk_pixbuf_loader_new): Documented.
4654 (gdk_pixbuf_loader_finalize): Call the parent class finalize
4656 (gdk_pixbuf_loader_write): Use size_t for count.
4658 1999-10-27 Michael Fulbright <drmike@redhat.com>
4660 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
4661 logic so we only try to close loader if it wasn't previously closed.
4663 1999-10-27 Michael Fulbright <drmike@redhat.com>
4665 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of

4692 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
4694 1999-10-22 Havoc Pennington <hp@pobox.com>
4696 * src/io-xpm.c (mem_buffer): Clean up stupid
4697 increment-inside-array-dereference thing
4699 * src/testpixbuf.c: Add XPM data tests.
4701 * src/io-xpm.c: Make the XPM data buffer const, fix const
4702 correctness throughout the code.
4704 1999-10-22 Havoc Pennington <hp@pobox.com>
4706 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

4714 function, loads pixbuf from xpm data
4715 (image_handler_load): Add g_return_if_fail() to ensure the same
4716 module isn't loaded twice. Add g_module_symbol() to scan for XPM

4721 * src/io-png.c (image_load): Patch from Kristian Hogsberg
4722 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
4723 buffers; the rows can be read in directly into the main pixel
4726 1999-10-20 Federico Mena Quintero <federico@redhat.com>
4728 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
4730 1999-10-20 Federico Mena Quintero <federico@redhat.com>
4732 * configure.in: Bumped version number to 0.3.
4734 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
4735 version number for the library.
4737 1999-10-20 Federico Mena Quintero <federico@redhat.com>
4739 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
4740 all memory management of the buffer is done by libart.

4749 symbols. Saving will not be implemented in GdkPixbuf.
4751 * src/io-gif.c: Removed the saving stub.
4752 (image_load): Fixed memory management to fail gracefully if we run
4753 out of memory while loading the image. Close the gif file when we
4754 are done. This still needs more error handling for the DGif
4757 * src/io-jpeg.c (image_load): Some robustness fixes.
4759 * src/io-png.c: Removed the saving stuff.
4760 (image_load): Some memory management fixes.

4772 1999-10-18 Federico Mena Quintero <federico@redhat.com>
4774 * src/*: Reindented to use the GNOME Indentation. Renamed
4775 GdkPixBuf to GdkPixbuf, for consistency with the function names
4776 (and it is also easier to type) :-)
4778 1999-10-18 Havoc Pennington <hp@pobox.com>
4780 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
4782 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
4784 1999-10-18 Havoc Pennington <hp@pobox.com>
4786 * Makefile.am (SUBDIRS): Remove "macros"
4788 * configure.in: Don't use GNOME_INIT, handle case where we are
4789 inside gnome-libs. AM_PATH_GTK for the GIF test

4792 comment out testpixbuf for now
4794 1999-10-18 Federico Mena Quintero <federico@redhat.com>
4796 * configure.in: Use $GTK_LIBS as the extra libs when checking for
4797 libgif/libungif, as they need the X libraries. Fixes bug #2472.
4799 1999-10-10 Cody Russell <bratsche@dfw.net>
4800 * src/gdk-pixbuf-drawable.c: core function now determines whether
4801 the requested geometry is on screen or not, and if some is not
4802 then the request is clamped to geometry that is on the screen.
4804 Changed 'pixbuf' to 'art_pixbuf' in core function.
4806 1999-10-08 Michael Fulbright <drmike@redhat.com>
4808 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

4813 1999-10-07 Cody Russell <bratsche@dfw.net>
4814 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
4815 them, but I wrote them).
4817 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
4820 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
4821 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

4846 * src/io-bmp.c (image_load): ditto.
4848 * src/io-gif.c (image_load): ditto.
4850 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
4852 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
4853 it doesn't crash scaling with alpha.
4855 1999-09-17 Federico Mena Quintero <federico@redhat.com>
4857 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
4859 * src/io-gif.c (image_load): Likewise.
4861 * src/io-jpeg.c (image_load): Likewise.

4867 * src/io-xpm.c (_pixbuf_create_from_xpm): Likewise.
4869 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_image): Added an assertion
4870 for the ref_count to be != 0.
4872 * src/gdk-pixbuf.c (gdk_pixbuf_ref): Be more paranoid with sanity
4874 (gdk_pixbuf_unref): Fix incorrect sanity check and comparison.
4876 1999-08-09 Federico Mena Quintero <federico@nuclecu.unam.mx>
4878 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
4879 to unallocated memory (row_ptr), and fixed its type as well. Take
4880 into account the ArtPixbuf's rowstride when assigning the row
4883 * src/gdk-pixbuf.c: Fixup includes.
4885 * src/gdk-pixbuf-io.c: Likewise.
4887 Sat Jul 31 19:19:47 CEST 1999
4889 * src/gdk-pixbuf-io.c:
4890 * src/io-png.c: Fixed two obvious C syntax bugs
4892 1999-07-29 Mark Crichton <crichton@gimp.org>
4894 * src/io-png.c (image_save): Added PNG saving function
4896 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
4897 image_save(GdkPixBuf *p, FILE *f, ...)
4900 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
4902 * src/Makefile.am (*_LIB): Only build the relevant loaders which
4903 require extra libraries if we actually have those libraries.
4905 1999-07-23 Richard Hestilow <hestgray@ionet.net>
4907 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
4908 * gdk_pixbufConf.sh.in: Added for gnome-config
4910 * configure.in: Modified to generate gdk_pixbufConf.sh
4912 1999-07-20 Mark Crichton <crichton@gimp.org>
4914 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
4915 calculation needs to be done.
4917 1999-07-18 Larry Ewing <lewing@gimp.org>
4922 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
4923 error cases but one or two in the common case. There are probably
4924 a few small ones left.
4926 1999-07-18 Mark Crichton <crichton@gimp.org>
4928 * configure.in: removed version.h.
4930 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
4933 1999-07-17 Mark Crichton <crichton@gimp.org>
4935 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
4936 (gdk_pixbuf_rotate): Added pixbuf rotation code.
4937 (gdk_pixbuf_scale): Changed // comments to /* */
4939 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
4942 1999-07-16 Larry Ewing <lewing@gimp.org>
4944 * src/testpixbuf.c (expose_func): reverted the expose everything
4945 changes, I'm not sure why these went in.
4946 (config_func): bring this up to date with the new pixbuf_scale
4949 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
4950 loading code so that poeple can diagnose problems better.
4952 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
4953 no longer allocates a new pixbuf, which make things nicer for the
4954 rest of the code. Unfortunately there is still a problem with
4955 scaling rgba images.
4957 1999-07-16 Mark Crichton <crichton@gimp.org>
4959 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
4960 calls gdk_pixbuf_scale. However, something is not working.
4961 N.B.: current pixmap is now stored in user_data with a key of
4964 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
4965 Something is still borked, however.
4967 1999-07-15 Larry Ewing <lewing@gimp.org>
4969 * src/io-jpeg.c (image_load): add raph@gimp.org's fix to the jpeg
4972 * src/testpixbuf.c (main): fix up the file routines a little so
4973 that you can load multiple files given the file names
4975 1999-07-14 Larry Ewing <lewing@gimp.org>
4977 * src/testpixbuf.c (expose_func): added an almost proper expose
4978 handler for testpixbuf
4980 1999-07-13 Mark Crichton <crichton@gimp.org>
4982 * configure.in: Fixed GIF check. Replaced " with '
4983 * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale
4985 1999-07-13 Mark Crichton <crichton@gimp.org>
4987 * configure.in: I am a bonehead. Added gif-lib check.
