306 find the nearest possible output size which libjpeg can produce
307 that is still larger than the desired size.
309 2002-07-06 Matthias Clasen <maclas@gmx.de>
311 * io-tiff.c (tiff_set_error): Handle global_error == NULL
313 (tiff_image_parse): Don't trust TIFFRGBAImageBegin to set

323 on unchecked reallocs.
324 (DecodeHeader, DecodeColormap, decode_bitmasks,

326 throughout. Change signatures where necessary to pass the
328 (OneLine16): Fix loading of 16bpp BI_RGB bmps.
329 (DoCompressed): Rewritten to properly support BI_RLE4 and
332 Support for compressed ras images (#84994):
334 * io-ras.c (RAS2State): Error on unsupported ras variations.
335 (OneLine8): Fix colormap indexing.

344 (gdk_pixbuf__jpeg_image_load,
345 gdk_pixbuf__jpeg_image_load_increment): Allocate a pixbuf with
346 alpha for 4-channel jpegs and call convert_cmyk_to_rgb for these.

350 2002-06-28 Sven Neumann <sven@gimp.org>
352 * gdk-pixbuf-csource.c (print_blurb): converted a Tab to spaces.
354 Thu Jun 13 18:11:11 2002 Owen Taylor <otaylor@redhat.com>
356 * pixops/pixops.c: Fix problem where when no alpha was
357 involved, we scaled rather than composited, but then
358 went ahead and composited anyways. (#76958, Patch
359 from Matthias Clasen). Needs to be merged to GNOME
362 2002-06-13 Matthias Clasen <maclas@gmx.de>
364 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
365 incrementally display incrementally loaded progressive jpegs.
367 2002-06-07 Federico Mena Quintero <federico@ximian.com>
370 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
371 starting at a specific memory location. We do this instead of
372 GINT32_FROM_LE() as the latter is simply dereferences a cast,
373 which doesn't work on platforms with alignment requirements.
376 2002-06-01 Matthias Clasen <maclas@gmx.de>
378 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
379 with a C comment - those seem to be not uncommon, e.g. the Gimp
380 produces them. (#82706)
382 * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
384 (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.
386 2002-05-22 Tor Lillqvist <tml@iki.fi>

391 * Makefile.am: Pass GTK_BINARY_VERSION.
393 2002-05-22 Federico Mena Quintero <federico@ximian.com>
395 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
396 account!!! Fixes #82515.
398 [This bug is not present in the GNOME 1.4 branch as its XPM loader
399 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
400 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
402 [IMPORTANT: The comment above is to make my life easier when
403 merging stuff across branches. If you make changes to gdk-pixbuf
404 in either branch, please include a comment in the ChangeLog that
405 indicates whether this should be merged into the other branch.

423 2002-05-07 Michael Natterer <mitch@gimp.org>
425 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
426 conditionally like the dynamic ones so --without-lib<foo> is
427 honored when building with --disable-modules. (#66867)
429 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
431 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to

437 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
438 restriction from the description of png tEXt parameters.
440 * io-png.c (png_text_to_pixbuf_option):
441 (gdk_pixbuf__png_image_save): If libpng supports it,
442 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
444 2002-04-11 Matthias Clasen <maclas@gmx.de>
446 More fixes for #77807:
448 * io-tga.c (get_contiguous_pixbuf): Helper function to create
449 a pixbuf with a contiguous pixel array while being careful about
452 * io-tga.c (fill_in_context, get_image_pseudocolor,

454 get_contiguous_pixbuf instead of manually allocating image
457 * io-xpm.c (pixbuf_create_from_xpm):
458 * io-pnm.c (gdk_pixbuf__pnm_image_load):
459 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
460 instead of manually allocating image storage.
462 2002-04-09 Matthias Clasen <maclas@gmx.de>
464 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
465 priv->image_module->module_name instead of image_type which may
468 2002-04-06 Matthias Clasen <maclas@gmx.de>
470 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
471 gdk_pixbuf_new instead of manually allocating image storage. This
472 gives us a good rowstride and overflow checks. (#77807)
474 2002-04-05 Matthias Clasen <maclas@gmx.de>
476 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
477 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable

485 2002-03-29 Matthias Clasen <maclas@gmx.de>
487 * io-png.c (png_simple_error_callback): libpng error handlers must
488 not return to their callers, thus longjmp out. This prevents
489 annoying stderr output from the default error handler.
491 2002-03-27 Matthias Clasen <maclas@gmx.de>
493 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
495 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
496 end_info. Also call png_read_end to check proper ending of the png
497 file and catch text chunks after the image data.
499 2002-03-27 Matthias Clasen <maclas@gmx.de>
501 * io-png.c (gdk_pixbuf__png_image_load,
502 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
503 instead of system malloc.
505 2002-03-26 Matthias Clasen <maclas@gmx.de>
507 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
509 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
510 context->buf on error.
512 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
513 stop_load even for short images to prevent memleaks.
515 2002-03-25 Matthias Clasen <maclas@gmx.de>
517 * io-png.c (setup_png_transformations): Changed signature to
518 return success and set a GError parameter, adjusted all callers.
519 Also work around a possible FPE in libpng and always check that
520 the new info is sane.
522 2002-03-23 Matthias Clasen <maclas@gmx.de>
524 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
525 context->updated_func is NULL during a nonincremental load.
526 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
528 2002-03-18 Matthias Clasen <maclas@gmx.de>
530 * io-tga.c: Fix assumptions on rowstride by manually allocating a
531 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
532 Support grayscale + alpha (which can be written, but not read (!)
535 2002-03-15 Matthias Clasen <maclas@gmx.de>
537 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
539 2002-03-13 Matthias Clasen <maclas@gmx.de>

947 Thu Sep 20 17:22:48 2001 Owen Taylor <otaylor@redhat.com>
949 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
950 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't
951 work here since we are using the raw file descriptor. So, we call lseek()
952 on the fileno(f) before using it. (#60840).

956 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,

973 2001-09-17 Matt Wilson <msw@redhat.com>

1012 - four valid ppm's, eight invalid (matthiasc@poet.de)
1013 - one invalid xpm (matthiasc@poet.de)
1014 - one valid tga, one invalid (sandmann@daimi.au.dk)
1015 - one invalid tiff (sandmann@daimi.au.dk
1017 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
1019 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
1020 fail - detect it when it happens

1028 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
1030 * Makefile.am: don't used BUILT_SOURCES to build marshal
1031 files, as in conjunction with stamp files, this can
1032 lead to endless rebuilding loops.

1036 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1

1077 * pixops/pixops.c: applied some simple but effective optimizations
1078 to pixops_composite_nearest() and pixops_composite_color_nearest().
1080 2001-08-07 Sven Neumann <sven@gimp.org>
1082 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
1083 function, so that's what I did.

1094 2001-07-20 Hans Breuer <hans@breuer.org>
1096 * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
1097 pointer increment out of the macro, because at least one
1098 compiler (msvc 5.0) gets confused otherwise (applies the
1101 * gdk_pixbuf.def : updated exports
1103 * makefile.msc : reflect gdk-pixbuf-csource changes

1110 * io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
1112 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
1113 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
1114 unused locals and add an initial value to quiet the compiler's
1115 unintialized variable warning.
1116 * pixops/pixops.c: Put an ifdef around some dead code.
1118 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
1120 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
1121 over to the new include flags AC_SUBST(). (Problem
1122 pointed out by Mikael Hermansson.)
1124 2001-06-29 Havoc Pennington <hp@redhat.com>
1126 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): fix for

1134 2001-06-28 Havoc Pennington <hp@pobox.com>
1136 * gdk-pixdata.c: <string.h>
1138 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
1139 also leaking memory here from g_strdup_printf?)
1141 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
1143 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
1145 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
1146 instead from gdk_pixbuf_new_from_inline().
1148 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
1149 installed API for applications that need to serialize/deserialize
1150 on their own (gimp, BEAST).
1152 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
1153 program that can dump images in CSource format and Pixbuf
1154 stream format. supports RLE encoding, MACRO formatting etc...
1157 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
1159 * Makefile.am: Actually update timestamps, so rules don't
1162 2001-06-11 Havoc Pennington <hp@redhat.com>
1164 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
1165 already includes top_builddir
1167 2001-06-08 Havoc Pennington <hp@redhat.com>
1169 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
1170 bogus g_return_if_fail
1172 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
1173 likely timeout resolution, set it to an arbitrarily-chosen short
1175 Fixes bug #55953 from warmenhoven@yahoo.com
1177 2001-06-07 Havoc Pennington <hp@redhat.com>
1179 * Makefile.am: use Owen's new way of doing stampfiles/generated
1182 2001-06-07 Havoc Pennington <hp@redhat.com>

1186 2001-06-05 Havoc Pennington <hp@redhat.com>
1188 * test-loaders.c (main): use putenv not setenv, reported by
1191 2001-05-08 Havoc Pennington <hp@redhat.com>
1193 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1194 and fix behavior to still subst color if the original image
1197 2001-06-04 Havoc Pennington <hp@redhat.com>
1199 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1202 2001-06-01 Havoc Pennington <hp@redhat.com>
1204 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1205 Makes things a bit more robust, and adds test-loaders.c
1206 which is good for finding further robustness bugs to fix.
1208 * io-tiff.c: Try to work around libtiff suckiness a bit;
1209 put a giant thread lock on the whole loader,
1210 paranoically check both whether error handlers were called and
1211 also whether functions return false. Handle case where width or
1212 height is 0. Various cleanups.
1214 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1216 (png_error_callback): apparently libpng expects you to longjmp out
1219 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1220 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1222 (gif_get_lzw): check for out-of-memory
1223 (gif_prepare_lzw): catch/report an error
1224 (new_context): use try_malloc, since GifContext is nearly 70K
1225 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1226 so we don't crash later.
1228 * Makefile.am: Add test-loaders
1230 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1233 2001-05-29 Darin Adler <darin@eazel.com>
1235 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1237 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1239 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1240 fix up bmp decoder to:
1241 - adds 16 bpp bmp support (bug #53884)
1242 - adds OS/2 1.x format bmp support (bug #54964)
1243 - adds 4 bpp RLE compressed bmp support
1244 - adds 1 bpp colormap support
1245 - fixes negative height (top down) bmp support
1247 2001-05-25 Hans Breuer <hans@breuer.org>
1249 * gdk_pixbuf.def : reflect Havoc's recent api change
1251 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1253 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1254 excess $(GLIB_LIBS).
1256 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1258 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1260 2001-05-04 Havoc Pennington <hp@redhat.com>
1262 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1263 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1266 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1267 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1268 confusion of using "src" instead of "p".
1269 (pixops_composite_color_nearest): Use a more accurate (and
1270 correct, to begin with) compositing method. This cures checks
1271 showing through on images with no alpha.
1273 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1276 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1278 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1279 area_updated signal to use signed ints. Removed animation-related
1282 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1285 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1286 all the pesky details. Remove old frame-based API. Make
1287 GdkPixbufAnimation an abstract base class, derived by the loaders.
1289 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1291 * Makefile.am (LDADDS): Add $(MATH_LIB).
1293 2001-04-18 Havoc Pennington <hp@redhat.com>
1295 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1298 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1300 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1301 so we don't try to get <gtk/gtkobject.h> from standard search
1304 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1305 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1306 take gdk-pixbuf-marshal.h out of _la sources.
1308 2001-03-19 Tor Lillqvist <tml@iki.fi>
1310 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1312 * gdk_pixbuf.def: Update.
1314 * pixbufloader_*.def: Just export the fill_vtable functions now.
1316 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1318 * make-inline-pixbuf.c (main): Added logic to remove output when
1321 2001-03-14 Havoc Pennington <hp@redhat.com>
1323 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1324 from gdk-pixbuf-marshal.h, fixes parallel makes.
1326 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1328 * test-gdk-pixbuf.c: fixed includes.
1330 2001-02-18 Havoc Pennington <hp@pobox.com>
1332 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1333 (gdk_pixbuf_get_named_module): prepend underscore
1334 (gdk_pixbuf_get_module): prepend underscore
1336 2001-02-19 Havoc Pennington <hp@redhat.com>
1338 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1340 2001-02-17 Havoc Pennington <hp@pobox.com>
1342 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1344 2001-02-07 Alexander Larsson <alexl@redhat.com>
1346 * io-xpm.c (free_buffer):
1347 Use g_free, since the buffer is allocated with g_try_alloc().
1349 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1351 * gdk-pixbuf-data.c: Fixes a minor typo.
1353 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1355 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1356 we finally need the gobject->gruntime rename.
1358 * *.c: scratched calls to g_type_init(), there's simply no point in
1359 doing that, use gtk_init().
1361 2001-02-01 Havoc Pennington <hp@pobox.com>
1363 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1364 in struct to "priv" for C++
1366 2001-01-31 Havoc Pennington <hp@pobox.com>
1368 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1370 2001-01-26 Havoc Pennington <hp@redhat.com>
1372 * gdk-pixbuf-io.c (mname): fix included modules case.
1374 2001-01-22 Havoc Pennington <hp@redhat.com>
1376 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1377 from gdk_pixbuf_load_module
1379 2001-01-22 Havoc Pennington <hp@redhat.com>
1381 * Makefile.am: Add built marshaller files to support
1382 GdkPixbufLoader signals
1384 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1385 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1386 module location, rather than acting as a fallback, because we are
1387 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1389 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1391 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1392 from gtk, and add error to close(), because stop_load may do
1393 parsing of the image.
1395 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1397 * io-*.c: make individual operations static, and add fill_vtable
1398 functions which are exported. Fix the collection of type warnings
1399 that surfaced, including a number of functions that didn't
1400 properly take a GError and some that weren't
1401 const-correct. Involved adding error handling for a few loaders.
1403 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1405 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1406 a function that fills in the GdkPixbufModule vtable, instead of
1407 looking up all the image functions individually; this means we
1408 can get type safety within modules for the loader functions.
1409 Also it means you don't have to keep the statically compiled and
1410 GModule versions in sync.
1412 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1414 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1416 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1418 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1421 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1423 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1426 2001-01-20 John Harper <jsh@eazel.com>
1428 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1429 collision between Xlib's RdBitF.c and io-tiff.c
1431 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1434 [ merged from stable gdk-pixbuf module. Untested, but it
1435 compiles, and works fine in the stable module ]
1437 2001-01-18 Tor Lillqvist <tml@iki.fi>
1439 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1440 g_win32_get_package_installation_subdirectory() function. No need
1441 to include windows.h.
1442 (gtk_win32_get_installation_directory): Remove this then.
1444 2001-01-01 Havoc Pennington <hp@redhat.com>
1446 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
1447 @LIBTOOL_EXPORT_OPTIONS@
1449 2000-12-30 Tor Lillqvist <tml@iki.fi>
1451 * gdk_pixbuf.def: Update.
1453 2000-12-16 Havoc Pennington <hp@pobox.com>
1455 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1456 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1457 (gdk_pixbuf_frame_copy): new function
1458 (gdk_pixbuf_frame_free): new function
1459 (gdk_pixbuf_frame_get_type): new function
1460 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
1462 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
1464 * Makefile.am: Add -avoid-version for all modules.
1466 2000-11-13 Havoc Pennington <hp@redhat.com>
1468 * io-png.c (png_simple_error_callback): fix error message to not
1469 say "save" since it's used for loading
1471 2000-11-11 Hans Breuer <Hans@Breuer.Org>
1473 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1474 contained image handlers (!USE_G_MODULE). Files to save should
1475 be opened in binary mode, fopen(s, "wb").
1477 * io-xpm.c : added HAVE_UNISTD_H condition
1479 2000-11-11 Tor Lillqvist <tml@iki.fi>
1481 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1483 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1484 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1485 mktemp() and open()).
1487 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1489 2000-11-01 Havoc Pennington <hp@pobox.com>
1491 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1492 a pixbuf pointing to a subregion of another pixbuf.
1494 2000-10-16 Tor Lillqvist <tml@iki.fi>
1496 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1498 2000-10-16 Havoc Pennington <hp@redhat.com>
1500 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1501 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1502 add error reporting here also
1504 * make-inline-pixbuf.c (main): use GError
1506 * io-xpm.c: include unistd.h
1508 * gdk-pixbuf-util.c: include string.h
1510 * io-*.c: add error reporting
1512 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
1515 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
1517 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1520 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1521 a G_FILE_ERROR if we fail to write or close the file.
1523 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1524 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1525 the GError naming rules. Add GError** to load functions.
1527 2000-10-06 Havoc Pennington <hp@redhat.com>
1529 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1531 2000-10-06 Havoc Pennington <hp@redhat.com>

1589 2000-07-21 Larry Ewing <lewing@helixcode.com>
1591 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
1592 xpm at least supports the progressive interface like the one in

1645 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
1646 all three of these files are the JPEG image loader. (From
1649 2000-10-03 Tor Lillqvist <tml@iki.fi>
1651 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
1652 gdk-pixbuf's version number in the rule for makefile.mingw itself.
1654 * gdk_pixbuf.def: Add new entry points.
1656 2000-09-26 Havoc Pennington <hp@redhat.com>
1658 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
1659 function here, instead of putting it in a private GTK+ file.
1661 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
1662 enum here for the known formats of inlined pixbufs.
1663 Also, #define our file magic here.
1665 2000-06-23 Havoc Pennington <hp@redhat.com>
1667 * make-inline-pixbuf.c: Small program that creates C variable
1668 declarations of inline pixbuf data. This can be read
1669 by gdk_pixbuf_new_from_inline.
1671 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
1672 inline pixbuf data and create a pixbuf from it.
1674 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1676 2000-09-07 Tor Lillqvist <tml@iki.fi>
1678 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1681 2000-08-12 Tor Lillqvist <tml@iki.fi>
1683 * gdk_pixbuf.def: Add missing entry point.
1685 2000-08-10 Havoc Pennington <hp@redhat.com>
1687 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1688 (s/pixbuf_/pixbufloader_)
1690 2000-08-02 Tor Lillqvist <tml@iki.fi>
1696 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1698 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1699 one. Fix names of DLLs to have '-' instead of '_'.
1701 2000-07-31 Elliot Lee <sopwith@redhat.com>
1702 * io-wbmp.c: Some bug fixes - now tested to work.
1704 2000-07-27 Elliot Lee <sopwith@redhat.com>
1706 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1707 gdk_pixbuf_get_named_module() function to facilitate above change
1708 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1709 Implement loader for WBMP format.
1710 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1712 2000-07-23 Tor Lillqvist <tml@iki.fi>
1717 * pixops/makefile.mingw.in
1718 * pixbuf_*.def: New files.
1721 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1723 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1724 New function, to get the GTK+ installation directory from
1725 the Windows Registry, where the installation program
1726 for whatever software includes GTK+ has stored it.
1728 Used to avoid having hardcoding the directory where to look for
1729 loaders. This function is needed by gtk, too, so it should
1730 really be just in one place. Maybe a small static library
1731 one level up from here?
1733 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1734 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1735 Open file in binary mode. This *is* standard C. (No-op on Unix,
1738 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1740 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1741 mktemp() and open().
1742 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1744 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1745 pseudo-op. Conditionalise on __MINGW32__, but probably
1746 should conditionalise on Gas version instead? Or could we
1747 do without .type on all systems?
1749 * pixops/timescale.c: Use g_get_current_time()
1750 instead of gettimeofday().
1752 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1754 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1756 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1758 * gdk-pixbuf.c: Add <string.h> include.
1760 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1762 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1763 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1764 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1765 use g_object_new() instead of g_type_create_instance() which
1766 is a private function for fundamental type implementations.
1768 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1770 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1771 soname scheme for gdk-pixbuf.
1773 2000-06-21 Havoc Pennington <hp@pobox.com>
1775 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1776 (i.e. derivation is not allowed, and there are no virtual methods
1778 (gdk_pixbuf_preinit): Call g_type_init() here.
1779 (gdk_pixbuf_init): Add a user-friendly init function, for users
1780 of standalone gdk-pixbuf
1782 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1783 way GdkPixbufAnimation was done.
1785 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1786 gdk_pixbuf_finalize() from API, since these are broken and don't
1787 make sense with new GObject stuff.
1789 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1791 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1792 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1795 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1797 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1798 so I needed something to warm my thighs. Running plain infinite
1799 loops on your laptop to make it hot is not very much fun. A demo
1800 of the gdk-pixbuf scaling functions is way better, and looks
1803 * configure.in (AC_OUTPUT): Added the demo Makefile.
1805 * Makefile.am (SUBDIRS): Added the demo directory.
1807 2000-06-09 Larry Ewing <lewing@helixcode.com>
1809 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1810 setjmp for the png error handler. It seems setting the error
1811 handling functions does not avoid the jump, and so not calling
1812 setjmp was causing the incremental loader to jump into lala land.
1813 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1814 not sure this one is actually required but the docs say it must be
1815 set for every call to a png_* function.
1816 Also changed the comment to reflect the fact that setting the
1817 error handlers does _not_ avoid the longjmp.
1819 2000-06-06 Larry Ewing <lewing@helixcode.com>
1821 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1822 take frame offest into account when trying to calculate the
1823 animation bbox. Also set the width to the width not the height.
1824 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1825 calculate bbox because now we finally have all the offset
1826 information for each frame.
1828 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1830 * configure.in: add some gtk parameters to the
1831 GDK_PIXBUF_LIBÃ�²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1832 fight in my crusade for strange prefix compile...
1834 2000-05-30 Not Zed <NotZed@HelixCode.com>
1836 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
1837 Initialise the error handler exit routine to our own. Note this
1838 means that every function that accesses the jpeg lib on this
1839 object MUST do a setjmp.
1840 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
1841 lib for handling fatal error.
1842 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
1843 your applications dont quit if there's a jpeg error!
1845 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
1847 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
1848 from Frank de Lange <frank@unternet.org>.
1850 2000-05-09 Darin Adler <darin@eazel.com>
1852 * gdk-pixbuf/test-gdk-pixbuf.c:
1853 Fixed includes to get rid of accidental GNOME dependency.
1855 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
1856 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
1858 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
1860 * configure.in: Bumped version number to 0.8.0.
1862 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
1863 file was not being distributed.
1865 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
1867 2000-05-09 Darin Adler <darin@eazel.com>
1869 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
1870 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
1871 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
1872 formats to 32-bit formats to re-use the high bits of the color values
1873 so that white maps to full white.
1875 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
1877 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
1878 detailed information about the structure and algorithms
1879 of pixops so people can fix it instead of breaking it.
1881 2000-05-04 Darin Adler <darin@eazel.com>
1883 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
1884 (composite_pixel), (composite_line):
1885 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
1886 Now that Owen explained the algorithm, I think I implemented it
1887 right for the cases where the destination pixbuf is not opaque.
1888 The test does seem to confirm it.
1890 2000-05-04 Darin Adler <darin@eazel.com>
1892 * gdk-pixbuf/.cvsignore:
1893 * gdk-pixbuf/Makefile.am:
1894 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
1895 (load_pixel), (simple_composite_test_one),
1896 (simple_composite_test_one_type), (simple_composite_test), (main):
1897 Added some tests of composite to highlight problems in the old
1898 implementation. These tests run without any user interaction.
1899 Just do "make check".
1901 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
1902 (composite_pixel), (composite_line): Fix composite to do a textbook
1903 "A over B" composite. This was clearly the intent, and it was easy
1904 to fix the code to do it. (Note to those that read my earlier tries
1905 at a patch; this version fixes typos that were present in all
1906 my patch attempts. I checked the final version by adding more tests.)
1908 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
1910 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
1911 offset y coordinate accordining to render_y0.
1913 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
1916 2000-04-22 James Henstridge <james@daa.com.au>
1918 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
1919 package to the devel package. The only file installed in bin is
1920 gdk-pixbuf-config, which belongs in -devel. This should allow having
1921 multiple versions of the main gdk-pixbuf package installed.
1923 2000-04-17 Karl Eichwalder <ke@suse.de>
1925 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
1926 Reported by Jens Finke.
1928 2000-04-14 Tomasz KÃ�³opczko <kloczek@pld.org.pl>
1930 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
1931 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
1933 2000-04-13 James Henstridge <james@daa.com.au>
1935 * configure.in: when performing the configure check to see if
1936 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
1937 rather than the other way round. Also, call AC_MSG_RESULT in the
1938 even that dynamic modules were not supported.
1940 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
1942 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
1943 hook to the last unref operation.
1945 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
1946 function to set the last unref handler for a pixbuf.
1947 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
1948 It calls the pixbuf's destroy notification function and frees the
1949 GdkPixbuf structure itself.
1950 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
1953 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
1954 for the last unref handler and its user data.
1956 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
1957 g_new0() to allocate the pixbuf.
1959 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
1960 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
1961 was not specifying the `frame' argument.
1963 * gdk-pixbuf/gdk-pixbuf-animation.c
1964 (gdk_pixbuf_animation_get_width): Fixed docstring.
1965 (gdk_pixbuf_animation_get_height): Likewise.
1966 (gdk_pixbuf_animation_get_num_frames): Likewise.
1967 (gdk_pixbuf_animation_get_frames): Likewise.
1969 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1972 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1974 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1976 * doc/tmpl/refcounting.sgml: Updated with the information about
1977 the last unref handler.
1979 * doc/tmpl/*.sgml: Markup tweaks.
1981 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1982 update the libtool version number for libgnomecanvaspixbuf as
1984 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
1985 as well, or the old ones won't work with the new stuff. Also,
1986 renamed the modules as follows.
1988 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
1989 modules are called "libpixbufloader-<format>.so" instead of
1990 "libpixbuf-<format>.so". They needed renaming so that the new
1991 loaders won't overwrite the old ones; even with the versioning
1992 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
1995 2000-04-12 Paolo Molaro <lupus@debian.org>
1997 * .cvsignore, src/.cvsignore: shut up cvs.
1999 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
2001 Most of this patch is based on a patch by Havoc Pennington
2002 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
2003 remove the libart dependency.
2005 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
2006 (GdkColorspace): New enum that for now only contains
2008 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
2009 notification function.
2010 (GdkInterpType): New num with interpolation types.
2012 * *.[ch]: Replace the libart stuff with our own stuff.
2014 * pixops/*.[ch]: Likewise.
2016 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
2017 declarations of the GdkPixbuf structures.
2019 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
2021 (gdk_pixbuf_get_format): Constify.
2022 (gdk_pixbuf_get_n_channels): Constify.

2026 (gdk_pixbuf_get_width): Constify.
2027 (gdk_pixbuf_get_height): Constify.
2028 (gdk_pixbuf_get_rowstride): Constify.
2030 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
2033 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
2034 bits_per_sample argument; currently only 8 bits per sample are
2037 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
2039 (gdk_pixbuf_frame_get_x_offset): New accessor.
2040 (gdk_pixbuf_frame_get_y_offset): New accessor.
2041 (gdk_pixbuf_frame_get_delay_time): New accessor.
2042 (gdk_pixbuf_frame_get_action): New accessor.
2044 * gdk-pixbuf/gdk-pixbuf-render.c
2045 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
2046 mask rectangle for pixbufs without an alpha channel, set the
2047 *mask_return to NULL.
2049 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
2051 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
2053 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
2054 preconditions. Maybe we should also check for the colorspace,
2055 bits per pixel, and such.
2056 (gdk_pixbuf_composite): Likewise.
2057 (gdk_pixbuf_composite_color): Likewise.
2058 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
2059 cannot allocate the new pixbuf.
2060 (gdk_pixbuf_composite_color_simple): Likewise.
2062 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
2063 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
2066 * gdk-pixbuf/io-bmp.c: Fix includes.
2068 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
2073 * configure.in: Removed checks for libart.
2075 * gdk-pixbuf/Makefile.am: Removed references to libart.
2076 (noinst_HEADERS): Added gdk-pixbuf-private.h.
2078 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
2079 the version number of the libtool library to indicate that this
2080 definitely is not compatible with the old usage. I know you love
2083 * configure.in: Bumped version number to 0.7.0.
2087 * gdk-pixbuf-config.in (--libs): We no longer require libart.
2089 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
2091 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
2093 2000-04-06 Jonathan Blandford <jrb@redhat.com>
2095 * gdk-pixbuf/testanimation.c (main): add more info to the
2096 testanimation frames.
2098 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
2100 * gdk-pixbuf/gdk-pixbuf-animation.c
2101 (gdk_pixbuf_animation_get_width): New accessor function.
2102 (gdk_pixbuf_animation_get_height): New accessor function.
2103 (gdk_pixbuf_animation_get_num_frames): New accessor function.
2104 (gdk_pixbuf_animation_get_frames): New accessor function.
2106 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
2108 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
2109 is private information, and the art_pixbuf will go away soon.
2111 2000-03-31 Mark Crichton <crichton@gimp.org>
2113 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
2114 and gdk_pixbuf_get_artpixbuf accessor functions.
2116 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
2118 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
2119 gboolean instead of int.
2121 2000-03-29 Radek Doulik <rodo@helixcode.com>
2123 * gdk-pixbuf/gdk-pixbuf-animation.c
2124 (gdk_pixbuf_animation_new_from_file): same as below
2126 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
2127 height in GdkPixbufAnimation
2129 2000-03-28 Radek Doulik <rodo@helixcode.com>
2131 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
2132 context->frame_done_func and context->anim_done_func to make
2133 progressive animation loading work
2135 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
2136 added priv->pixbuf = NULL as pixbuf is now in frame (and to make
2137 gdk_pixbuf_loader_prepare happy)
2138 (gdk_pixbuf_loader_frame_done): update animation bbox
2140 * gdk-pixbuf/gdk-pixbuf.h: added bbox size (width, height) to
2143 2000-03-27 Radek Doulik <rodo@helixcode.com>
2145 * gdk-pixbuf/io-gif.c (gif_get_lzw): use frame_len and frame_width
2146 instead of width and height
2148 2000-03-27 Owen Taylor <otaylor@redhat.com>
2150 * gdk-pixbuf/pixops/pixops.c: Fix problem with
2151 precendence of >> and & which was keeping composite_color
2152 from working with non-gray images.

2584 animation functions here.

2606 gdk-pixbuf-animation.c.
2608 * doc/tmpl/animation.sgml: Populated. It is still missing a

2633 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2634 correctly. Progressive loading needs some work, but that all
2635 needs doing from the gdk-pixbuf-loader end, not here.
2637 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2639 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2640 moved the file here. It seems natural to put this function here,
2641 as that's where the gdk_pixbuf_new_from_file function is, but it's
2642 still a little convoluted. The source files might be played with

2659 * gdk-pixbuf/gnome-canvas-pixbuf.c
2660 (gnome_canvas_pixbuf_class_init): Renamed arguments to
2661 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for

2691 Filled in body of function.
2692 (rgbconvert): Added GdkColormap parameter, and to all conversion
2694 (convert_real_slow): New function - should convert ANY visual/data
2695 format properly, but it aint fast. Used as a fallback when an
2696 optimised routine wont match.
2697 (rgbconvert): Do very specific tests on the data format to verify
2698 properly if the optimised version will do, otherwise use the
2699 fallback function for all other data formats.
2701 * gdk-pixbuf/Makefile.am: Re-enabled building of
2702 textpixbuf-drawable.
2704 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use

2716 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2717 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2718 checks and API definition. The body needs filling in and it needs
2719 to do the Right Thing(tm) for pixmaps plus the given colormap and
2720 windows and their own colormaps.
2722 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2723 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.

2739 reference counting for GdkPixbuf structures.
2741 1999-12-07 Martin Baulig <martin@home-of-linux.org>
2743 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
2744 include $(GNOME_LIBS) here.
2746 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2748 Added missing "include <string.h>" to:
2749 * gdk-pixbuf/io-ras.c

2760 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2761 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2762 want, send me a patch to do the conditional stuff properly.
2763 Otherwise, please read the GNOME Programming Guidelines,
2764 especially the "CVS policies" section.
2766 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
2768 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.

2775 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
2777 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
2778 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
2780 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
2782 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
2785 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
2786 (Windows Cursor files). These are identical to .ICO files,
2787 except for the signature and 2 extra fields for the hotspot.
2789 1999-12-03 Federico Mena Quintero <federico@redhat.com>
2791 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):

2797 explain this function better.
2799 1999-12-02 Federico Mena Quintero <federico@redhat.com>
2801 Source files moved from src/ to gdk-pixbuf/, to be consistent with

2876 1999-11-29 Owen Taylor <otaylor@redhat.com>
2878 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
2879 Keep the mask around until after we draw ... since
2880 the GC changes aren't flushed to the X server until we
2881 draw, destroying it before that may result in BadPixmap
2884 1999-11-30 Havoc Pennington <hp@pobox.com>
2886 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
2888 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
2890 1999-11-29 Federico Mena Quintero <federico@redhat.com>
2892 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
2893 should be made conditional, not blindly commented out.
2895 1999-11-29 Jonathan Blandford <jrb@redhat.com>
2897 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
2898 handle .ico files. Cool.
2900 1999-11-24 Jonathan Blandford <jrb@redhat.com>
2902 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
2905 1999-11-24 James Henstridge <james@daa.com.au>
2907 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
2908 top builddir rather than src. This still builds fine, and does not
2909 get gtk-doc into an infinite loop when trying to find all the source
2912 1999-11-23 Jonathan Blandford <jrb@redhat.com>
2914 * Removed #PRAGMA } from headers. Also, make compile if you don't
2915 have it installed, already.
2917 1999-11-22 Federico Mena Quintero <federico@redhat.com>
2919 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
2920 temporary buffer to the size of the interesction of the bounding
2921 box and the expose area, not the whole expose area. This speeds
2924 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
2925 not paint black on the mask, since we already cleared it in a
2926 single gdk_draw_rectangle() operation.
2928 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
2930 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
2932 1999-11-22 Havoc Pennington <hp@pobox.com>
2934 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
2935 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
2936 dependencies to LIBADD variables for loadable modules. Necessary
2937 for a Java dynamic loading thing to be able to figure it out.
2939 1999-11-22 Havoc Pennington <hp@pobox.com>
2941 * src/io-png.c (image_load_increment): Call the update_area
2942 callback depending on the number of rows loaded in this increment.
2944 * src/testpixbuf.c (main): slow down the progressive load demo
2946 1999-11-16 Havoc Pennington <hp@pobox.com>
2948 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
2950 1999-11-22 Jonathan Blandford <jrb@redhat.com>
2952 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
2953 for srcdir != buildir != . Beats me why; I can't figure it out.
2954 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
2956 1999-11-21 Jonathan Blandford <jrb@redhat.com>
2958 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
2959 <arjan@fenrus.demon.nl>
2961 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2963 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
2964 Rework/reorder of the code. Each case has been separated into
2965 another function; its big but it should be quick.
2966 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
2967 opaque alpha information. Not all depths/formats have been
2968 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
2970 1999-11-17 Larry Ewing <lewing@gimp.org>
2972 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2973 implement the bounds method correctly.
2974 (compute_viewport_affine): compute the affine need to fit the
2975 image within the viewport given by the args.
2976 (compute_render_affine): call compute_viewport_affine.
2978 1999-11-16 Havoc Pennington <hp@pobox.com>
2980 * src/gdk-pixbuf-drawable.h: Use includes from the current
2981 directory, not the system directory.
2983 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
2985 * src/testpixbuf-drawable.c: use includes from the current directory
2986 rather then from the system include directory as gdk-pixbuf
2987 includes are not yet installed when this is compiled.
2989 1999-11-13 Cody Russell <bratsche@dfw.net>
2990 * src/testpixbuf-drawable.c: Added a test program for drawable
2993 * src/Makefile.am: Build testpixbuf-drawable.

3010 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
3013 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
3014 correctly. Patch from Arjan to do so.
3016 1999-11-10 Michael Fulbright <drmike@redhat.com>
3018 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM

3028 1999-11-10 Federico Mena Quintero <federico@redhat.com>
3030 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
3033 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3035 * src/io-png.c: Fixed some incompatible pointer initializations.

3039 1999-11-09 Michael Fulbright <drmike@redhat.com>
3041 * src/testpixbuf.c: Fixed it to use timeout to read from file
3042 for progressive loading. Set TBF_KBPS=n, where n is the number of
3043 kilobytes/second to simulate in downloading. n has to be an integer.
3045 * src/io-jpeg.c: Slight cosmetic cleanup.
3047 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
3048 PBM loading has a similar problem and will address tomorrow.
3050 1999-11-09 Havoc Pennington <hp@pobox.com>
3052 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
3053 gdk-pixbuf-drawable stuff.
3055 1999-11-09 Federico Mena Quintero <federico@redhat.com>

3059 1999-11-09 Michael Fulbright <drmike@redhat.com>
3061 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
3062 all types of PNM files now.
3064 * src/io-jpeg.c (image_load_increment): Figured out problem with
3065 loading Progressive JPEG's progressively (say that 10 times fast).
3066 Currently for Progressive JPEG's the entire image is loaded before
3067 it is displayed. libjpeg supports a fancier mechanism which I may
3070 With these changes all JPEG formats appear to load properly for me.
3072 1999-11-08 Jonathan Blandford <jrb@redhat.com>
3074 * src/io-ras.c (image_load_increment): Final patch from Arjan.
3075 Seems to do progressive loading.
3077 1999-11-08 Michael Fulbright <drmike@redhat.com>
3079 * src/io-pnm.c image_load (): Fixed so we do not create a separate
3080 pixel buffer when reading in image - we reuse the pixel data in
3081 the GdkPixbuf structure instead.
3083 1999-11-08 Michael Fulbright <drmike@redhat.com>
3085 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
3086 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
3087 I can't seem to find a utility to convert into this format.
3088 Next is to add progressive loading support for the PNM format.
3090 1999-11-07 Federico Mena Quintero <federico@redhat.com>
3092 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation

3102 * src/io-ras.c (image_load): new file from Arjan van de Ven
3103 <arjan@fenrus.demon.nl> to begin the ras loader.
3105 1999-11-05 Federico Mena Quintero <federico@redhat.com>

3140 docs, explain what a dither offset is for.
3141 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3142 this function vs. gdk_pixbuf_render_to_drawable().
3144 1999-11-04 Havoc Pennington <hp@pobox.com>
3146 * configure.in: Use libart-config correctly; find gnome-config
3147 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3150 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3153 Patch untested in the inside-gnome-libs case, I need to commit
3154 then check out to the gnome-libs I'm using.

3237 (gnome_canvas_pixbuf_set_arg): add x,y args.
3238 (gnome_canvas_pixbuf_get_arg): add x,y args.
3239 (recompute_bounding_box): simply code using ArtDrect and the
3240 render_affine. Removed compute_xform_vectors as it was no longer
3243 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3245 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
3246 doofus. Return a distance, not a boolean, for opaque images.
3248 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
3249 rounding of bounding box coordinates.
3250 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
3251 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
3253 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3255 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
3257 1999-11-03 Michael Fulbright <drmike@redhat.com>
3259 * src/io-jpg.c (image_load_increment): Fixed code which moved
3260 buffer around as new data comes in to work properly. JPEG progressive
3261 loading should be working now except for grayscale JPEG's, which I
3262 will look into next.
3264 1999-11-03 <sopwith@redhat.com>
3265 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
3266 Also put dot printing back in.
3268 1999-11-03 <jrb@redhat.com>
3270 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
3273 1999-11-02 Cody Russell <bratsche@dfw.net>
3274 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
3275 if part of the requested image is offscreen, rather than clipping
3278 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3280 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
3281 for interlacing and progressive loading.
3283 1999-11-02 Cody Russell <bratsche@dfw.net>
3284 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
3285 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
3287 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3289 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
3290 It's a little slow though. )-:
3292 1999-11-02 Elliot Lee <sopwith@redhat.com>
3293 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
3294 write/load_increment operations const-correct.
3296 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3298 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
3299 Implemented the ::point() method. We do a simple containment test
3300 instead of a full distance calculation since the canvas is going
3301 to change to that scheme, anyways.
3303 1999-11-02 Elliot Lee <sopwith@redhat.com>
3305 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
3306 that are read from the input file.
3308 1999-11-02 Larry Ewing <lewing@gimp.org>
3310 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
3312 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
3315 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3317 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3318 affine computation code from ::draw() to here, since it is needed
3319 by ::point() as well.
3321 1999-11-02 Elliot Lee <sopwith@redhat.com>
3323 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3324 three functions, and eliminate duplication of code from write()
3325 and close(). Also fix bug where the 128-byte header was being
3328 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3329 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3330 bounding box computation.
3332 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3334 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3335 Drawing affines seem to work. Bounding box is fubared. ::point()
3336 is not implemented. This is a work in progress.
3338 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3341 * configure.in: Sigh. We need to link in libgnomeui for the
3342 canvas stuff. This mess will disappear when gdk-pixbuf gets
3343 folded into gnome-libs.
3345 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3347 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3348 the right size, at a minimum, even if the image is squished and
3350 (ReadImage): lets get the offset right. This will let transparent
3353 1999-10-29 Michael Fulbright <drmike@redhat.com>
3355 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3356 image width was not a multiple of 4 - always use the
3357 gdk_pixbuf rowstride to increment pointers!
3359 1999-10-29 Michael Fulbright <drmike@redhat.com>
3361 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3362 Currently does not handle either progressive jpeg files (jpeg
3363 files with multiple scans at different quality settings), but
3364 I plan on adding this support soon. These are fairly rare in
3365 my experience, so it shouldn't slow people down too much.
3366 Grayscale jpegs also don't work but that should be easy to fix.
3368 1999-10-29 Michael Fulbright <drmike@redhat.com>
3370 * src/testpixbuf.c: Added title to windows so you can identify
3371 progressive and file windows.
3373 1999-10-29 Michael Fulbright <drmike@redhat.com>
3375 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3376 load the image handler when we determine the image type.
3378 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3379 previously static function load_image_handler () to
3380 a public function gdk_pixbuf_load_module (). It is needed in
3381 gdk-pixbuf-loader.c to load image handler modules. This function
3382 is different from gdk_pixbuf_get_module (), which only returns
3383 a reference to the required handler, because it actually loads
3384 the handler into memory. Both actions should possibly be combined
3385 in a convenience function since one w/o the other doesn't seem to
3388 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3390 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
3393 1999-10-28 Federico Mena Quintero <federico@redhat.com>
3395 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3396 function to render a portion of a pixbuf to a drawable. Ignores
3397 alpha information and takes in a GC.
3398 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3399 portion of a pixbuf to a drawable. It automatically creates a GC
3400 and a clipping mask for alpha pixbufs.
3402 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3404 * src/gdk-pixbuf.h: turned convenience macros into convenience
3405 functions so some error checking could be added.
3407 * src/io-tiff.c (image_load_increment): started work on the tiff
3408 non-incremental loader.
3409 (image_begin_load): Finished the incremental loader.
3411 * src/io-gif.c (image_load_increment): started work on the gif
3414 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
3416 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3418 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3419 function to threshold a pixbuf's alpha channel into a bitmap.
3421 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3422 contemplate future extensions to ArtPixBuf's formats.
3424 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3426 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3427 macros to fetch the ArtPixBuf's fields.
3429 1999-10-27 Havoc Pennington <hp@pobox.com>
3431 * src/testpixbuf.c (main): Display the progressive load
3433 * src/io-png.c (setup_png_transformations): Break transformation
3434 code into separate function
3435 (png_info_callback): Use setup_png_transformations
3437 1999-10-27 Havoc Pennington <hp@pobox.com>
3439 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3440 properly whether the XPM module has already been loaded
3441 (gdk_pixbuf_new_from_file): Check properly if loader module
3442 was already loaded (was checking if load symbol was present
3443 in order to decide whether to re-load; should check module !=
3444 NULL, then load != NULL)
3445 (image_handler_load): Check in present working directory,
3446 makes it easier to debug for now
3447 (file_formats): This array initializer was seriously on crack,
3448 was assigning a function pointer to a GModule*
3450 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
3452 1999-10-27 Havoc Pennington <hp@pobox.com>
3454 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_finalize):
3455 Fix typo that prevented compilation
3456 (gdk_pixbuf_loader_destroy): ditto
3458 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3460 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
3461 GdkPixbufLoader, not a GtkObject.
3462 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
3463 (gdk_pixbuf_loader_get_type): Documented.
3464 (gdk_pixbuf_loader_class_init): Initialize the parent class
3466 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
3467 class destroy function.
3468 (gdk_pixbuf_loader_new): Documented.
3469 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3471 (gdk_pixbuf_loader_write): Use size_t for count.
3473 1999-10-27 Michael Fulbright <drmike@redhat.com>
3475 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3476 logic so we only try to close loader if it wasn't previously closed.
3478 1999-10-27 Michael Fulbright <drmike@redhat.com>
3480 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of
3481 pixbuf_loader properly initialized.
3483 * src/testpixbuf.c: Made sure we cleanup pixbuf_loader properly
3486 1999-10-26 Jonathan Blandford <jrb@redhat.com>
3488 * src/gdk-pixbuf-io.c (image_handler_load): load the vtable fully.
3490 * src/gdk-pixbuf-loader.c: Finished initial cut at the object.

3504 1999-10-25 Federico Mena Quintero <federico@redhat.com>
3506 * configure.in (CFLAGS): Patch from Uwe Koloska
3507 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3509 1999-10-22 Havoc Pennington <hp@pobox.com>
3511 * src/io-xpm.c (mem_buffer): Clean up stupid
3512 increment-inside-array-dereference thing
3514 * src/testpixbuf.c: Add XPM data tests.
3516 * src/io-xpm.c: Make the XPM data buffer const, fix const
3517 correctness throughout the code.
3519 1999-10-22 Havoc Pennington <hp@pobox.com>
3521 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()
3523 1999-10-22 Havoc Pennington <hp@pobox.com>
3525 * src/io-xpm.c (image_load_xpm_data): Export this symbol for
3526 loading an XPM from memory.

3529 function, loads pixbuf from xpm data
3530 (image_handler_load): Add g_return_if_fail() to ensure the same
3531 module isn't loaded twice. Add g_module_symbol() to scan for XPM
3534 1999-10-22 Federico Mena Quintero <federico@redhat.com>
3536 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3537 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
3538 buffers; the rows can be read in directly into the main pixel
3541 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3543 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
3545 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3547 * configure.in: Bumped version number to 0.3.
3549 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
3550 version number for the library.
3552 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3554 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
3555 all memory management of the buffer is done by libart.
3557 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
3558 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
3560 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
3561 terms of the libart functions. Removed the old code.
3563 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
3564 symbols. Saving will not be implemented in GdkPixbuf.
3566 * src/io-gif.c: Removed the saving stub.
3567 (image_load): Fixed memory management to fail gracefully if we run
3568 out of memory while loading the image. Close the gif file when we
3569 are done. This still needs more error handling for the DGif
3572 * src/io-jpeg.c (image_load): Some robustness fixes.
3574 * src/io-png.c: Removed the saving stuff.
3575 (image_load): Some memory management fixes.
3577 * src/io-tiff.c (image_load): Ditto.
3579 * src/io-xpm.c (pixbuf_create_from_xpm): Ditto.

3583 * subautogen.sh: New name for macros/autogen.sh
3585 * autogen.sh: use subautogen.sh
3587 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3589 * src/*: Reindented to use the GNOME Indentation. Renamed
3590 GdkPixBuf to GdkPixbuf, for consistency with the function names
3591 (and it is also easier to type) :-)
3593 1999-10-18 Havoc Pennington <hp@pobox.com>
3595 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
3597 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
3599 1999-10-18 Havoc Pennington <hp@pobox.com>
3601 * Makefile.am (SUBDIRS): Remove "macros"
3603 * configure.in: Don't use GNOME_INIT, handle case where we are
3604 inside gnome-libs. AM_PATH_GTK for the GIF test
3606 * src/Makefile.am: Change flags to work without libgnomeui,
3607 comment out testpixbuf for now
3609 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3611 * configure.in: Use $GTK_LIBS as the extra libs when checking for
3612 libgif/libungif, as they need the X libraries. Fixes bug #2472.
3614 1999-10-10 Cody Russell <bratsche@dfw.net>
3615 * src/gdk-pixbuf-drawable.c: core function now determines whether
3616 the requested geometry is on screen or not, and if some is not
3617 then the request is clamped to geometry that is on the screen.
3619 Changed 'pixbuf' to 'art_pixbuf' in core function.
3621 1999-10-08 Michael Fulbright <drmike@redhat.com>
3623 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.
3625 * src/testpifbuf: Changed test program to display cdrom from rgb data
3626 if no filename given to test program.
3628 1999-10-07 Cody Russell <bratsche@dfw.net>
3629 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
3630 them, but I wrote them).
3632 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
3635 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
3636 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.
3638 * src/gdk-pixbuf-drawable.c: Added #include "gdk-pixbuf-drawable.h"
3641 * src/gdk-pixbuf-drawable.[ch]: Changed functions to return
3642 GdkPixBuf* instead of ArtPixBuf*.
3644 1999-09-22 Michael Meeks <michael@nuclecu.unam.mx>

3650 GdkPixBufUnrefFunc + gdk_pixbuf_new.
3652 * src/io-jpeg.c (image_load): clean to use gdk_pixbuf_new.
3654 * src/io-xpm.c (_pixbuf_create_from_xpm): ditto.
3656 * src/io-tiff.c (image_load): ditto + fix leak
3658 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
3659 crashes this module ( add warning :-)
3661 * src/io-bmp.c (image_load): ditto.
3663 * src/io-gif.c (image_load): ditto.
3665 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
3667 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
3668 it doesn't crash scaling with alpha.
3670 1999-09-17 Federico Mena Quintero <federico@redhat.com>
3672 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
3674 * src/io-gif.c (image_load): Likewise.
3676 * src/io-jpeg.c (image_load): Likewise.
3678 * src/io-png.c (image_load): Likewise.
3680 * src/io-tiff.c (image_load): Likewise.
3682 * src/io-xpm.c (_pixbuf_create_from_xpm): Likewise.
3684 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_image): Added an assertion
3685 for the ref_count to be != 0.
3687 * src/gdk-pixbuf.c (gdk_pixbuf_ref): Be more paranoid with sanity
3689 (gdk_pixbuf_unref): Fix incorrect sanity check and comparison.
3691 1999-08-09 Federico Mena Quintero <federico@nuclecu.unam.mx>
3693 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
3694 to unallocated memory (row_ptr), and fixed its type as well. Take
3695 into account the ArtPixbuf's rowstride when assigning the row
3698 * src/gdk-pixbuf.c: Fixup includes.
3700 * src/gdk-pixbuf-io.c: Likewise.
3702 Sat Jul 31 19:19:47 CEST 1999
3704 * src/gdk-pixbuf-io.c:
3705 * src/io-png.c: Fixed two obvious C syntax bugs
3707 1999-07-29 Mark Crichton <crichton@gimp.org>
3709 * src/io-png.c (image_save): Added PNG saving function
3711 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
3712 image_save(GdkPixBuf *p, FILE *f, ...)
3715 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
3717 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3718 require extra libraries if we actually have those libraries.
3720 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3722 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
3723 * gdk_pixbufConf.sh.in: Added for gnome-config
3725 * configure.in: Modified to generate gdk_pixbufConf.sh
3727 1999-07-20 Mark Crichton <crichton@gimp.org>
3729 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3730 calculation needs to be done.
3732 1999-07-18 Larry Ewing <lewing@gimp.org>
3737 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3738 error cases but one or two in the common case. There are probably
3739 a few small ones left.
3741 1999-07-18 Mark Crichton <crichton@gimp.org>
3743 * configure.in: removed version.h.
3745 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3748 1999-07-17 Mark Crichton <crichton@gimp.org>
3750 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
3751 (gdk_pixbuf_rotate): Added pixbuf rotation code.
3752 (gdk_pixbuf_scale): Changed // comments to /* */
3754 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
3757 1999-07-16 Larry Ewing <lewing@gimp.org>
3759 * src/testpixbuf.c (expose_func): reverted the expose everything
3760 changes, I'm not sure why these went in.
3761 (config_func): bring this up to date with the new pixbuf_scale
3764 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3765 loading code so that poeple can diagnose problems better.
3767 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3768 no longer allocates a new pixbuf, which make things nicer for the
3769 rest of the code. Unfortunately there is still a problem with
3770 scaling rgba images.
3772 1999-07-16 Mark Crichton <crichton@gimp.org>
3774 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3775 calls gdk_pixbuf_scale. However, something is not working.
3776 N.B.: current pixmap is now stored in user_data with a key of
3779 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
