311 separate scaling is required.
312 (gdk_pixbuf_loader_load_module): Add size_func as first argument.
313 (gdk_pixbuf_loader_close): If necessary scale the image

321 (gdk_pixbuf__jpeg_image_load_increment): Call size_func, and
322 find the nearest possible output size which libjpeg can produce
323 that is still larger than the desired size.
325 2002-07-06 Matthias Clasen <maclas@gmx.de>
327 * io-tiff.c (tiff_set_error): Handle global_error == NULL
329 (tiff_image_parse): Don't trust TIFFRGBAImageBegin to set

342 throughout. Change signatures where necessary to pass the
344 (OneLine16): Fix loading of 16bpp BI_RGB bmps.
345 (DoCompressed): Rewritten to properly support BI_RLE4 and
348 Support for compressed ras images (#84994):
350 * io-ras.c (RAS2State): Error on unsupported ras variations.
351 (OneLine8): Fix colormap indexing.

360 (gdk_pixbuf__jpeg_image_load,
361 gdk_pixbuf__jpeg_image_load_increment): Allocate a pixbuf with

366 2002-06-28 Sven Neumann <sven@gimp.org>
368 * gdk-pixbuf-csource.c (print_blurb): converted a Tab to spaces.
370 Thu Jun 13 18:11:11 2002 Owen Taylor <otaylor@redhat.com>
372 * pixops/pixops.c: Fix problem where when no alpha was
373 involved, we scaled rather than composited, but then
374 went ahead and composited anyways. (#76958, Patch
375 from Matthias Clasen). Needs to be merged to GNOME
378 2002-06-13 Matthias Clasen <maclas@gmx.de>
380 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
381 incrementally display incrementally loaded progressive jpegs.
383 2002-06-07 Federico Mena Quintero <federico@ximian.com>
386 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
387 starting at a specific memory location. We do this instead of
388 GINT32_FROM_LE() as the latter is simply dereferences a cast,
389 which doesn't work on platforms with alignment requirements.
392 2002-06-01 Matthias Clasen <maclas@gmx.de>
394 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting
395 with a C comment - those seem to be not uncommon, e.g. the Gimp
396 produces them. (#82706)
398 * io-xbm.c (read_bitmap_file_data): Don't leak memory on certain
400 (gdk_pixbuf__xbm_image_load_real): Don't leak memory on valid inputs.
402 2002-05-22 Tor Lillqvist <tml@iki.fi>

407 * Makefile.am: Pass GTK_BINARY_VERSION.
409 2002-05-22 Federico Mena Quintero <federico@ximian.com>
411 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
412 account!!! Fixes #82515.
414 [This bug is not present in the GNOME 1.4 branch as its XPM loader
415 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
416 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
418 [IMPORTANT: The comment above is to make my life easier when
419 merging stuff across branches. If you make changes to gdk-pixbuf
420 in either branch, please include a comment in the ChangeLog that
421 indicates whether this should be merged into the other branch.
424 2002-05-18 Matthias Clasen <maclas@gmx.de>

439 2002-05-07 Michael Natterer <mitch@gimp.org>
441 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
442 conditionally like the dynamic ones so --without-lib<foo> is
443 honored when building with --disable-modules. (#66867)
445 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
447 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to
449 * test-loaders.c, test-images.h: remove
451 2002-04-24 Matthias Clasen <maclas@gmx.de>
453 * gdk-pixbuf-io.c (gdk_pixbuf_save): Remove the ISO8859-1
454 restriction from the description of png tEXt parameters.
456 * io-png.c (png_text_to_pixbuf_option):
457 (gdk_pixbuf__png_image_save): If libpng supports it,
458 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
460 2002-04-11 Matthias Clasen <maclas@gmx.de>
462 More fixes for #77807:
464 * io-tga.c (get_contiguous_pixbuf): Helper function to create
465 a pixbuf with a contiguous pixel array while being careful about
468 * io-tga.c (fill_in_context, get_image_pseudocolor,

470 get_contiguous_pixbuf instead of manually allocating image
473 * io-xpm.c (pixbuf_create_from_xpm):
474 * io-pnm.c (gdk_pixbuf__pnm_image_load):
475 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
476 instead of manually allocating image storage.
478 2002-04-09 Matthias Clasen <maclas@gmx.de>
480 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
481 priv->image_module->module_name instead of image_type which may
484 2002-04-06 Matthias Clasen <maclas@gmx.de>
486 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
487 gdk_pixbuf_new instead of manually allocating image storage. This
488 gives us a good rowstride and overflow checks. (#77807)
490 2002-04-05 Matthias Clasen <maclas@gmx.de>
492 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of
493 the image by using a TIFFRGBAImage{Begin,Get,End} with suitable

501 2002-03-29 Matthias Clasen <maclas@gmx.de>
503 * io-png.c (png_simple_error_callback): libpng error handlers must
504 not return to their callers, thus longjmp out. This prevents
505 annoying stderr output from the default error handler.
507 2002-03-27 Matthias Clasen <maclas@gmx.de>
509 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
511 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
512 end_info. Also call png_read_end to check proper ending of the png
513 file and catch text chunks after the image data.
515 2002-03-27 Matthias Clasen <maclas@gmx.de>
517 * io-png.c (gdk_pixbuf__png_image_load,
518 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
519 instead of system malloc.
521 2002-03-26 Matthias Clasen <maclas@gmx.de>
523 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
525 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
526 context->buf on error.
528 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
529 stop_load even for short images to prevent memleaks.
531 2002-03-25 Matthias Clasen <maclas@gmx.de>
533 * io-png.c (setup_png_transformations): Changed signature to
534 return success and set a GError parameter, adjusted all callers.
535 Also work around a possible FPE in libpng and always check that
536 the new info is sane.
538 2002-03-23 Matthias Clasen <maclas@gmx.de>

965 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
966 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't

1028 - four valid ppm's, eight invalid (matthiasc@poet.de)
1029 - one invalid xpm (matthiasc@poet.de)
1030 - one valid tga, one invalid (sandmann@daimi.au.dk)
1031 - one invalid tiff (sandmann@daimi.au.dk
1033 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
1035 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
1036 fail - detect it when it happens

1041 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
1044 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
1046 * Makefile.am: don't used BUILT_SOURCES to build marshal
1047 files, as in conjunction with stamp files, this can
1048 lead to endless rebuilding loops.

1086 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): Fail with a suitable
1087 error if buffer allocation fails.
1088 * io-ico.c: Make .ICO loader more robust.
1089 All of these are due to sandmann@daimi.au.dk (#50187)
1091 2001-08-19 Sven Neumann <sven@gimp.org>
1093 * pixops/pixops.c: applied some simple but effective optimizations
1094 to pixops_composite_nearest() and pixops_composite_color_nearest().
1096 2001-08-07 Sven Neumann <sven@gimp.org>
1098 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
1099 function, so that's what I did.
1101 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
1103 * gdk-pixdata.c: Fix a typo.
1105 2001-07-30 Hans Breuer <hans@breuer.org>

1110 2001-07-20 Hans Breuer <hans@breuer.org>
1112 * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
1113 pointer increment out of the macro, because at least one
1114 compiler (msvc 5.0) gets confused otherwise (applies the
1117 * gdk_pixbuf.def : updated exports
1119 * makefile.msc : reflect gdk-pixbuf-csource changes

1123 * gdk-pixbuf-csource.c: Add missing <stdlib.h> include.
1124 * io-png.c: (setup_png_transformations): Add ifdef so we compile
1125 without warnings with G_DISABLE_CHECKS on.
1126 * io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
1128 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
1129 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
1130 unused locals and add an initial value to quiet the compiler's
1131 unintialized variable warning.
1132 * pixops/pixops.c: Put an ifdef around some dead code.
1134 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
1136 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
1137 over to the new include flags AC_SUBST(). (Problem
1138 pointed out by Mikael Hermansson.)
1140 2001-06-29 Havoc Pennington <hp@redhat.com>
1142 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): fix for

1148 gdk-pixbuf-csource.c: Fix args to g_type_init ().
1150 2001-06-28 Havoc Pennington <hp@pobox.com>
1152 * gdk-pixdata.c: <string.h>
1154 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
1155 also leaking memory here from g_strdup_printf?)
1157 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
1159 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
1161 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
1162 instead from gdk_pixbuf_new_from_inline().
1164 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
1165 installed API for applications that need to serialize/deserialize
1166 on their own (gimp, BEAST).
1168 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
1169 program that can dump images in CSource format and Pixbuf
1170 stream format. supports RLE encoding, MACRO formatting etc...
1173 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
1175 * Makefile.am: Actually update timestamps, so rules don't
1178 2001-06-11 Havoc Pennington <hp@redhat.com>
1180 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
1181 already includes top_builddir
1183 2001-06-08 Havoc Pennington <hp@redhat.com>
1185 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
1186 bogus g_return_if_fail
1188 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
1189 likely timeout resolution, set it to an arbitrarily-chosen short
1191 Fixes bug #55953 from warmenhoven@yahoo.com
1193 2001-06-07 Havoc Pennington <hp@redhat.com>
1195 * Makefile.am: use Owen's new way of doing stampfiles/generated
1198 2001-06-07 Havoc Pennington <hp@redhat.com>

1202 2001-06-05 Havoc Pennington <hp@redhat.com>
1204 * test-loaders.c (main): use putenv not setenv, reported by
1207 2001-05-08 Havoc Pennington <hp@redhat.com>
1209 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1210 and fix behavior to still subst color if the original image
1213 2001-06-04 Havoc Pennington <hp@redhat.com>
1215 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1218 2001-06-01 Havoc Pennington <hp@redhat.com>
1220 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1221 Makes things a bit more robust, and adds test-loaders.c
1222 which is good for finding further robustness bugs to fix.
1224 * io-tiff.c: Try to work around libtiff suckiness a bit;
1225 put a giant thread lock on the whole loader,
1226 paranoically check both whether error handlers were called and
1227 also whether functions return false. Handle case where width or
1228 height is 0. Various cleanups.
1230 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1232 (png_error_callback): apparently libpng expects you to longjmp out
1235 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1236 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1238 (gif_get_lzw): check for out-of-memory
1239 (gif_prepare_lzw): catch/report an error
1240 (new_context): use try_malloc, since GifContext is nearly 70K
1241 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1242 so we don't crash later.
1244 * Makefile.am: Add test-loaders
1246 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1249 2001-05-29 Darin Adler <darin@eazel.com>
1251 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1253 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1255 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1256 fix up bmp decoder to:
1257 - adds 16 bpp bmp support (bug #53884)
1258 - adds OS/2 1.x format bmp support (bug #54964)
1259 - adds 4 bpp RLE compressed bmp support
1260 - adds 1 bpp colormap support
1261 - fixes negative height (top down) bmp support
1263 2001-05-25 Hans Breuer <hans@breuer.org>
1265 * gdk_pixbuf.def : reflect Havoc's recent api change
1267 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1269 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1270 excess $(GLIB_LIBS).
1272 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1274 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1276 2001-05-04 Havoc Pennington <hp@redhat.com>
1278 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1279 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1282 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1283 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1284 confusion of using "src" instead of "p".
1285 (pixops_composite_color_nearest): Use a more accurate (and
1286 correct, to begin with) compositing method. This cures checks
1287 showing through on images with no alpha.
1289 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1292 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1294 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1295 area_updated signal to use signed ints. Removed animation-related
1298 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1301 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1302 all the pesky details. Remove old frame-based API. Make
1303 GdkPixbufAnimation an abstract base class, derived by the loaders.
1305 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1307 * Makefile.am (LDADDS): Add $(MATH_LIB).
1309 2001-04-18 Havoc Pennington <hp@redhat.com>
1311 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1314 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1316 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1317 so we don't try to get <gtk/gtkobject.h> from standard search
1320 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1321 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1322 take gdk-pixbuf-marshal.h out of _la sources.
1324 2001-03-19 Tor Lillqvist <tml@iki.fi>
1326 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1328 * gdk_pixbuf.def: Update.
1330 * pixbufloader_*.def: Just export the fill_vtable functions now.
1332 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1334 * make-inline-pixbuf.c (main): Added logic to remove output when
1337 2001-03-14 Havoc Pennington <hp@redhat.com>
1339 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1340 from gdk-pixbuf-marshal.h, fixes parallel makes.
1342 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1344 * test-gdk-pixbuf.c: fixed includes.
1346 2001-02-18 Havoc Pennington <hp@pobox.com>
1348 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1349 (gdk_pixbuf_get_named_module): prepend underscore
1350 (gdk_pixbuf_get_module): prepend underscore
1352 2001-02-19 Havoc Pennington <hp@redhat.com>
1354 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1356 2001-02-17 Havoc Pennington <hp@pobox.com>
1358 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1360 2001-02-07 Alexander Larsson <alexl@redhat.com>
1362 * io-xpm.c (free_buffer):
1363 Use g_free, since the buffer is allocated with g_try_alloc().
1365 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1367 * gdk-pixbuf-data.c: Fixes a minor typo.
1369 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1371 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1372 we finally need the gobject->gruntime rename.
1374 * *.c: scratched calls to g_type_init(), there's simply no point in
1375 doing that, use gtk_init().
1377 2001-02-01 Havoc Pennington <hp@pobox.com>
1379 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1380 in struct to "priv" for C++
1382 2001-01-31 Havoc Pennington <hp@pobox.com>
1384 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1386 2001-01-26 Havoc Pennington <hp@redhat.com>
1388 * gdk-pixbuf-io.c (mname): fix included modules case.
1390 2001-01-22 Havoc Pennington <hp@redhat.com>
1392 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1393 from gdk_pixbuf_load_module
1395 2001-01-22 Havoc Pennington <hp@redhat.com>
1397 * Makefile.am: Add built marshaller files to support
1398 GdkPixbufLoader signals
1400 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1401 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1402 module location, rather than acting as a fallback, because we are
1403 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1405 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1407 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1408 from gtk, and add error to close(), because stop_load may do
1409 parsing of the image.
1411 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1413 * io-*.c: make individual operations static, and add fill_vtable
1414 functions which are exported. Fix the collection of type warnings
1415 that surfaced, including a number of functions that didn't
1416 properly take a GError and some that weren't
1417 const-correct. Involved adding error handling for a few loaders.
1419 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1421 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1422 a function that fills in the GdkPixbufModule vtable, instead of
1423 looking up all the image functions individually; this means we
1424 can get type safety within modules for the loader functions.
1425 Also it means you don't have to keep the statically compiled and
1426 GModule versions in sync.
1428 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1430 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1432 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1434 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1437 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1439 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1442 2001-01-20 John Harper <jsh@eazel.com>
1444 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1445 collision between Xlib's RdBitF.c and io-tiff.c
1447 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1450 [ merged from stable gdk-pixbuf module. Untested, but it
1451 compiles, and works fine in the stable module ]
1453 2001-01-18 Tor Lillqvist <tml@iki.fi>
1455 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1456 g_win32_get_package_installation_subdirectory() function. No need
1457 to include windows.h.
1458 (gtk_win32_get_installation_directory): Remove this then.
1460 2001-01-01 Havoc Pennington <hp@redhat.com>
1462 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
1463 @LIBTOOL_EXPORT_OPTIONS@
1465 2000-12-30 Tor Lillqvist <tml@iki.fi>
1467 * gdk_pixbuf.def: Update.
1469 2000-12-16 Havoc Pennington <hp@pobox.com>
1471 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1472 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1473 (gdk_pixbuf_frame_copy): new function
1474 (gdk_pixbuf_frame_free): new function
1475 (gdk_pixbuf_frame_get_type): new function
1476 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
1478 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
1480 * Makefile.am: Add -avoid-version for all modules.
1482 2000-11-13 Havoc Pennington <hp@redhat.com>
1484 * io-png.c (png_simple_error_callback): fix error message to not
1485 say "save" since it's used for loading
1487 2000-11-11 Hans Breuer <Hans@Breuer.Org>
1489 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1490 contained image handlers (!USE_G_MODULE). Files to save should
1491 be opened in binary mode, fopen(s, "wb").
1493 * io-xpm.c : added HAVE_UNISTD_H condition
1495 2000-11-11 Tor Lillqvist <tml@iki.fi>
1497 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1499 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1500 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1501 mktemp() and open()).
1503 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1505 2000-11-01 Havoc Pennington <hp@pobox.com>
1507 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1508 a pixbuf pointing to a subregion of another pixbuf.
1510 2000-10-16 Tor Lillqvist <tml@iki.fi>
1512 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1514 2000-10-16 Havoc Pennington <hp@redhat.com>
1516 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1517 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1518 add error reporting here also
1520 * make-inline-pixbuf.c (main): use GError
1522 * io-xpm.c: include unistd.h
1524 * gdk-pixbuf-util.c: include string.h
1526 * io-*.c: add error reporting
1528 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
1531 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
1533 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1536 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1537 a G_FILE_ERROR if we fail to write or close the file.
1539 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1540 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1541 the GError naming rules. Add GError** to load functions.
1543 2000-10-06 Havoc Pennington <hp@redhat.com>
1545 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1547 2000-10-06 Havoc Pennington <hp@redhat.com>

1605 2000-07-21 Larry Ewing <lewing@helixcode.com>
1607 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
1608 xpm at least supports the progressive interface like the one in
1609 io-tiff.c. This should be reimplemented as an actual progressive

1633 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
1635 2000-10-05 Havoc Pennington <hp@redhat.com>

1659 2000-10-05 Dan Winship <danw@helixcode.com>
1661 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
1662 all three of these files are the JPEG image loader. (From
1665 2000-10-03 Tor Lillqvist <tml@iki.fi>
1667 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
1668 gdk-pixbuf's version number in the rule for makefile.mingw itself.
1670 * gdk_pixbuf.def: Add new entry points.
1672 2000-09-26 Havoc Pennington <hp@redhat.com>
1674 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
1675 function here, instead of putting it in a private GTK+ file.
1677 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
1678 enum here for the known formats of inlined pixbufs.
1679 Also, #define our file magic here.
1681 2000-06-23 Havoc Pennington <hp@redhat.com>
1683 * make-inline-pixbuf.c: Small program that creates C variable
1684 declarations of inline pixbuf data. This can be read
1685 by gdk_pixbuf_new_from_inline.
1687 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
1688 inline pixbuf data and create a pixbuf from it.
1690 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1692 2000-09-07 Tor Lillqvist <tml@iki.fi>
1694 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1697 2000-08-12 Tor Lillqvist <tml@iki.fi>
1699 * gdk_pixbuf.def: Add missing entry point.
1701 2000-08-10 Havoc Pennington <hp@redhat.com>
1703 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1704 (s/pixbuf_/pixbufloader_)
1706 2000-08-02 Tor Lillqvist <tml@iki.fi>
1712 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1714 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1715 one. Fix names of DLLs to have '-' instead of '_'.
1717 2000-07-31 Elliot Lee <sopwith@redhat.com>
1718 * io-wbmp.c: Some bug fixes - now tested to work.
1720 2000-07-27 Elliot Lee <sopwith@redhat.com>
1722 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1723 gdk_pixbuf_get_named_module() function to facilitate above change
1724 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1725 Implement loader for WBMP format.
1726 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1728 2000-07-23 Tor Lillqvist <tml@iki.fi>
1733 * pixops/makefile.mingw.in
1734 * pixbuf_*.def: New files.
1737 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1739 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1740 New function, to get the GTK+ installation directory from
1741 the Windows Registry, where the installation program
1742 for whatever software includes GTK+ has stored it.
1744 Used to avoid having hardcoding the directory where to look for
1745 loaders. This function is needed by gtk, too, so it should
1746 really be just in one place. Maybe a small static library
1747 one level up from here?
1749 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1750 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1751 Open file in binary mode. This *is* standard C. (No-op on Unix,
1754 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1756 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1757 mktemp() and open().
1758 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1760 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1761 pseudo-op. Conditionalise on __MINGW32__, but probably
1762 should conditionalise on Gas version instead? Or could we
1763 do without .type on all systems?
1765 * pixops/timescale.c: Use g_get_current_time()
1766 instead of gettimeofday().
1768 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1770 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1772 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1774 * gdk-pixbuf.c: Add <string.h> include.
1776 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1778 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1779 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1780 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1781 use g_object_new() instead of g_type_create_instance() which
1782 is a private function for fundamental type implementations.
1784 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1786 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1787 soname scheme for gdk-pixbuf.
1789 2000-06-21 Havoc Pennington <hp@pobox.com>
1791 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1792 (i.e. derivation is not allowed, and there are no virtual methods
1794 (gdk_pixbuf_preinit): Call g_type_init() here.
1795 (gdk_pixbuf_init): Add a user-friendly init function, for users
1796 of standalone gdk-pixbuf
1798 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1799 way GdkPixbufAnimation was done.
1801 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1802 gdk_pixbuf_finalize() from API, since these are broken and don't
1803 make sense with new GObject stuff.
1805 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1807 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1808 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1811 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1813 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1814 so I needed something to warm my thighs. Running plain infinite
1815 loops on your laptop to make it hot is not very much fun. A demo
1816 of the gdk-pixbuf scaling functions is way better, and looks
1819 * configure.in (AC_OUTPUT): Added the demo Makefile.
1821 * Makefile.am (SUBDIRS): Added the demo directory.
1823 2000-06-09 Larry Ewing <lewing@helixcode.com>
1825 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1826 setjmp for the png error handler. It seems setting the error
1827 handling functions does not avoid the jump, and so not calling
1828 setjmp was causing the incremental loader to jump into lala land.
1829 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1830 not sure this one is actually required but the docs say it must be
1831 set for every call to a png_* function.
1832 Also changed the comment to reflect the fact that setting the
1833 error handlers does _not_ avoid the longjmp.
1835 2000-06-06 Larry Ewing <lewing@helixcode.com>
1837 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1838 take frame offest into account when trying to calculate the
1839 animation bbox. Also set the width to the width not the height.
1840 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1841 calculate bbox because now we finally have all the offset
1842 information for each frame.
1844 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1846 * configure.in: add some gtk parameters to the
1847 GDK_PIXBUF_LIBÃ�²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1848 fight in my crusade for strange prefix compile...
1850 2000-05-30 Not Zed <NotZed@HelixCode.com>
1852 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
1853 Initialise the error handler exit routine to our own. Note this
1854 means that every function that accesses the jpeg lib on this
1855 object MUST do a setjmp.
1856 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
1857 lib for handling fatal error.
1858 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
1859 your applications dont quit if there's a jpeg error!
1861 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
1863 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
1864 from Frank de Lange <frank@unternet.org>.
1866 2000-05-09 Darin Adler <darin@eazel.com>
1868 * gdk-pixbuf/test-gdk-pixbuf.c:
1869 Fixed includes to get rid of accidental GNOME dependency.
1871 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
1872 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
1874 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
1876 * configure.in: Bumped version number to 0.8.0.
1878 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
1879 file was not being distributed.
1881 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
1883 2000-05-09 Darin Adler <darin@eazel.com>
1885 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
1886 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
1887 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
1888 formats to 32-bit formats to re-use the high bits of the color values
1889 so that white maps to full white.
1891 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
1893 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
1894 detailed information about the structure and algorithms
1895 of pixops so people can fix it instead of breaking it.
1897 2000-05-04 Darin Adler <darin@eazel.com>
1899 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
1900 (composite_pixel), (composite_line):
1901 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
1902 Now that Owen explained the algorithm, I think I implemented it
1903 right for the cases where the destination pixbuf is not opaque.
1904 The test does seem to confirm it.
1906 2000-05-04 Darin Adler <darin@eazel.com>
1908 * gdk-pixbuf/.cvsignore:
1909 * gdk-pixbuf/Makefile.am:
1910 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
1911 (load_pixel), (simple_composite_test_one),
1912 (simple_composite_test_one_type), (simple_composite_test), (main):
1913 Added some tests of composite to highlight problems in the old
1914 implementation. These tests run without any user interaction.
1915 Just do "make check".
1917 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
1918 (composite_pixel), (composite_line): Fix composite to do a textbook
1919 "A over B" composite. This was clearly the intent, and it was easy
1920 to fix the code to do it. (Note to those that read my earlier tries
1921 at a patch; this version fixes typos that were present in all
1922 my patch attempts. I checked the final version by adding more tests.)
1924 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
1926 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
1927 offset y coordinate accordining to render_y0.
1929 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
1932 2000-04-22 James Henstridge <james@daa.com.au>
1934 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
1935 package to the devel package. The only file installed in bin is
1936 gdk-pixbuf-config, which belongs in -devel. This should allow having
1937 multiple versions of the main gdk-pixbuf package installed.
1939 2000-04-17 Karl Eichwalder <ke@suse.de>
1941 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
1942 Reported by Jens Finke.
1944 2000-04-14 Tomasz KÃ�³opczko <kloczek@pld.org.pl>
1946 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
1947 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
1949 2000-04-13 James Henstridge <james@daa.com.au>
1951 * configure.in: when performing the configure check to see if
1952 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
1953 rather than the other way round. Also, call AC_MSG_RESULT in the
1954 even that dynamic modules were not supported.
1956 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
1958 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
1959 hook to the last unref operation.
1961 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
1962 function to set the last unref handler for a pixbuf.
1963 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
1964 It calls the pixbuf's destroy notification function and frees the
1965 GdkPixbuf structure itself.
1966 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
1969 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
1970 for the last unref handler and its user data.
1972 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
1973 g_new0() to allocate the pixbuf.
1975 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
1976 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
1977 was not specifying the `frame' argument.
1979 * gdk-pixbuf/gdk-pixbuf-animation.c
1980 (gdk_pixbuf_animation_get_width): Fixed docstring.
1981 (gdk_pixbuf_animation_get_height): Likewise.
1982 (gdk_pixbuf_animation_get_num_frames): Likewise.
1983 (gdk_pixbuf_animation_get_frames): Likewise.
1985 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
1988 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
1990 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
1992 * doc/tmpl/refcounting.sgml: Updated with the information about
1993 the last unref handler.
1995 * doc/tmpl/*.sgml: Markup tweaks.
1997 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
1998 update the libtool version number for libgnomecanvaspixbuf as
2000 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
2001 as well, or the old ones won't work with the new stuff. Also,
2002 renamed the modules as follows.
2004 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
2005 modules are called "libpixbufloader-<format>.so" instead of
2006 "libpixbuf-<format>.so". They needed renaming so that the new
2007 loaders won't overwrite the old ones; even with the versioning
2008 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
2011 2000-04-12 Paolo Molaro <lupus@debian.org>
2013 * .cvsignore, src/.cvsignore: shut up cvs.
2015 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
2017 Most of this patch is based on a patch by Havoc Pennington
2018 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
2019 remove the libart dependency.
2021 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
2022 (GdkColorspace): New enum that for now only contains
2024 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
2025 notification function.
2026 (GdkInterpType): New num with interpolation types.
2028 * *.[ch]: Replace the libart stuff with our own stuff.
2030 * pixops/*.[ch]: Likewise.
2032 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
2033 declarations of the GdkPixbuf structures.
2035 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
2037 (gdk_pixbuf_get_format): Constify.

2046 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
2049 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
2050 bits_per_sample argument; currently only 8 bits per sample are
2053 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
2055 (gdk_pixbuf_frame_get_x_offset): New accessor.
2056 (gdk_pixbuf_frame_get_y_offset): New accessor.
2057 (gdk_pixbuf_frame_get_delay_time): New accessor.
2058 (gdk_pixbuf_frame_get_action): New accessor.
2060 * gdk-pixbuf/gdk-pixbuf-render.c
2061 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
2062 mask rectangle for pixbufs without an alpha channel, set the
2063 *mask_return to NULL.
2065 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
2067 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
2069 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
2070 preconditions. Maybe we should also check for the colorspace,
2071 bits per pixel, and such.
2072 (gdk_pixbuf_composite): Likewise.
2073 (gdk_pixbuf_composite_color): Likewise.
2074 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
2075 cannot allocate the new pixbuf.
2076 (gdk_pixbuf_composite_color_simple): Likewise.
2078 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
2079 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
2082 * gdk-pixbuf/io-bmp.c: Fix includes.
2084 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
2089 * configure.in: Removed checks for libart.
2091 * gdk-pixbuf/Makefile.am: Removed references to libart.
2092 (noinst_HEADERS): Added gdk-pixbuf-private.h.
2094 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
2095 the version number of the libtool library to indicate that this
2096 definitely is not compatible with the old usage. I know you love
2099 * configure.in: Bumped version number to 0.7.0.
2103 * gdk-pixbuf-config.in (--libs): We no longer require libart.
2105 * DEPENDS.libgdk_pixbuf: We no longer depend on libart.
2107 * gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
2109 2000-04-06 Jonathan Blandford <jrb@redhat.com>
2111 * gdk-pixbuf/testanimation.c (main): add more info to the
2112 testanimation frames.
2114 2000-04-04 Ettore Perazzoli <ettore@helixcode.com>
2116 * gdk-pixbuf/gdk-pixbuf-animation.c
2117 (gdk_pixbuf_animation_get_width): New accessor function.
2118 (gdk_pixbuf_animation_get_height): New accessor function.
2119 (gdk_pixbuf_animation_get_num_frames): New accessor function.
2120 (gdk_pixbuf_animation_get_frames): New accessor function.
2122 2000-04-01 Federico Mena Quintero <federico@helixcode.com>
2124 * gdk-pixbuf/gdk-pixbuf.c: Reverted Mark's change. The refcount
2125 is private information, and the art_pixbuf will go away soon.
2127 2000-03-31 Mark Crichton <crichton@gimp.org>
2129 * gdk-pixbuf/gdk-pixbuf.c: Added gdk_pixbuf_get_refcount
2130 and gdk_pixbuf_get_artpixbuf accessor functions.
2132 2000-03-29 Federico Mena Quintero <federico@helixcode.com>
2134 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_get_has_alpha): Return
2135 gboolean instead of int.
2137 2000-03-29 Radek Doulik <rodo@helixcode.com>
2139 * gdk-pixbuf/gdk-pixbuf-animation.c
2140 (gdk_pixbuf_animation_new_from_file): same as below
2142 * gdk-pixbuf/io-gif.c (gif_get_lzw): added update of width and
2143 height in GdkPixbufAnimation
2145 2000-03-28 Radek Doulik <rodo@helixcode.com>
2147 * gdk-pixbuf/io-gif.c (gif_get_lzw): test also for
2148 context->frame_done_func and context->anim_done_func to make
2149 progressive animation loading work
2151 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
2152 added priv->pixbuf = NULL as pixbuf is now in frame (and to make

2600 animation functions here.
2601 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
2602 animation if the loader does not support multiframe loading and

2615 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
2618 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
2619 with a reference count of 1.
2621 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
2622 gdk-pixbuf-animation.c.
2624 * doc/tmpl/animation.sgml: Populated. It is still missing a
2625 description of the overlay modes.

2643 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
2644 set to NULL here (specifically context->animation) was not being

2647 1999-12-20 Jonathan Blandford <jrb@redhat.com>
2649 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2650 correctly. Progressive loading needs some work, but that all
2651 needs doing from the gdk-pixbuf-loader end, not here.
2653 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2655 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2656 moved the file here. It seems natural to put this function here,
2657 as that's where the gdk_pixbuf_new_from_file function is, but it's
2658 still a little convoluted. The source files might be played with
2661 1999-12-14 Jonathan Blandford <jrb@redhat.com>

2671 Shaw <joe@off.net> for pointing this out.
2673 1999-12-13 Federico Mena Quintero <federico@redhat.com>
2675 * gdk-pixbuf/gnome-canvas-pixbuf.c
2676 (gnome_canvas_pixbuf_class_init): Renamed arguments to
2677 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
2678 consistency with the new canvas.
2679 (PixbufPrivate): Do the same renaming in the structure fields, for

2707 Filled in body of function.
2708 (rgbconvert): Added GdkColormap parameter, and to all conversion
2710 (convert_real_slow): New function - should convert ANY visual/data
2711 format properly, but it aint fast. Used as a fallback when an
2712 optimised routine wont match.
2713 (rgbconvert): Do very specific tests on the data format to verify
2714 properly if the optimised version will do, otherwise use the
2715 fallback function for all other data formats.
2717 * gdk-pixbuf/Makefile.am: Re-enabled building of
2718 textpixbuf-drawable.
2720 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use

2732 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2733 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2734 checks and API definition. The body needs filling in and it needs
2735 to do the Right Thing(tm) for pixmaps plus the given colormap and
2736 windows and their own colormaps.
2738 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for

2755 reference counting for GdkPixbuf structures.
2757 1999-12-07 Martin Baulig <martin@home-of-linux.org>
2759 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
2760 include $(GNOME_LIBS) here.
2762 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2764 Added missing "include <string.h>" to:

2776 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2777 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2778 want, send me a patch to do the conditional stuff properly.
2779 Otherwise, please read the GNOME Programming Guidelines,
2780 especially the "CVS policies" section.
2782 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
2784 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.

2794 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
2796 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
2798 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
2801 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files

2892 1999-11-29 Owen Taylor <otaylor@redhat.com>
2894 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
2895 Keep the mask around until after we draw ... since
2896 the GC changes aren't flushed to the X server until we
2897 draw, destroying it before that may result in BadPixmap
2900 1999-11-30 Havoc Pennington <hp@pobox.com>
2902 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
2904 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
2906 1999-11-29 Federico Mena Quintero <federico@redhat.com>
2908 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
2909 should be made conditional, not blindly commented out.
2911 1999-11-29 Jonathan Blandford <jrb@redhat.com>
2913 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
2914 handle .ico files. Cool.
2916 1999-11-24 Jonathan Blandford <jrb@redhat.com>
2918 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
2921 1999-11-24 James Henstridge <james@daa.com.au>
2923 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
2924 top builddir rather than src. This still builds fine, and does not
2925 get gtk-doc into an infinite loop when trying to find all the source
2928 1999-11-23 Jonathan Blandford <jrb@redhat.com>
2930 * Removed #PRAGMA } from headers. Also, make compile if you don't
2931 have it installed, already.
2933 1999-11-22 Federico Mena Quintero <federico@redhat.com>
2935 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
2936 temporary buffer to the size of the interesction of the bounding
2937 box and the expose area, not the whole expose area. This speeds
2940 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
2941 not paint black on the mask, since we already cleared it in a
2942 single gdk_draw_rectangle() operation.
2944 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
2946 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
2948 1999-11-22 Havoc Pennington <hp@pobox.com>
2950 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
2951 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
2952 dependencies to LIBADD variables for loadable modules. Necessary
2953 for a Java dynamic loading thing to be able to figure it out.
2955 1999-11-22 Havoc Pennington <hp@pobox.com>
2957 * src/io-png.c (image_load_increment): Call the update_area
2958 callback depending on the number of rows loaded in this increment.
2960 * src/testpixbuf.c (main): slow down the progressive load demo
2962 1999-11-16 Havoc Pennington <hp@pobox.com>
2964 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
2966 1999-11-22 Jonathan Blandford <jrb@redhat.com>
2968 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
2969 for srcdir != buildir != . Beats me why; I can't figure it out.
2970 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
2972 1999-11-21 Jonathan Blandford <jrb@redhat.com>
2974 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
2975 <arjan@fenrus.demon.nl>
2977 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2979 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
2980 Rework/reorder of the code. Each case has been separated into
2981 another function; its big but it should be quick.
2982 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
2983 opaque alpha information. Not all depths/formats have been
2984 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
2986 1999-11-17 Larry Ewing <lewing@gimp.org>
2988 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
2989 implement the bounds method correctly.
2990 (compute_viewport_affine): compute the affine need to fit the
2991 image within the viewport given by the args.
2992 (compute_render_affine): call compute_viewport_affine.
2994 1999-11-16 Havoc Pennington <hp@pobox.com>
2996 * src/gdk-pixbuf-drawable.h: Use includes from the current
2997 directory, not the system directory.
2999 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
3001 * src/testpixbuf-drawable.c: use includes from the current directory
3002 rather then from the system include directory as gdk-pixbuf
3003 includes are not yet installed when this is compiled.
3005 1999-11-13 Cody Russell <bratsche@dfw.net>
3006 * src/testpixbuf-drawable.c: Added a test program for drawable
3009 * src/Makefile.am: Build testpixbuf-drawable.

3029 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
3030 correctly. Patch from Arjan to do so.
3032 1999-11-10 Michael Fulbright <drmike@redhat.com>
3034 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM

3055 1999-11-09 Michael Fulbright <drmike@redhat.com>
3057 * src/testpixbuf.c: Fixed it to use timeout to read from file
3058 for progressive loading. Set TBF_KBPS=n, where n is the number of
3059 kilobytes/second to simulate in downloading. n has to be an integer.
3061 * src/io-jpeg.c: Slight cosmetic cleanup.
3063 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
3064 PBM loading has a similar problem and will address tomorrow.
3066 1999-11-09 Havoc Pennington <hp@pobox.com>
3068 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
3069 gdk-pixbuf-drawable stuff.
3071 1999-11-09 Federico Mena Quintero <federico@redhat.com>

3075 1999-11-09 Michael Fulbright <drmike@redhat.com>
3077 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
3078 all types of PNM files now.
3080 * src/io-jpeg.c (image_load_increment): Figured out problem with
3081 loading Progressive JPEG's progressively (say that 10 times fast).
3082 Currently for Progressive JPEG's the entire image is loaded before
3083 it is displayed. libjpeg supports a fancier mechanism which I may
3086 With these changes all JPEG formats appear to load properly for me.
3088 1999-11-08 Jonathan Blandford <jrb@redhat.com>
3090 * src/io-ras.c (image_load_increment): Final patch from Arjan.
3091 Seems to do progressive loading.
3093 1999-11-08 Michael Fulbright <drmike@redhat.com>
3095 * src/io-pnm.c image_load (): Fixed so we do not create a separate
3096 pixel buffer when reading in image - we reuse the pixel data in
3097 the GdkPixbuf structure instead.
3099 1999-11-08 Michael Fulbright <drmike@redhat.com>
3101 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
3102 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
3103 I can't seem to find a utility to convert into this format.
3104 Next is to add progressive loading support for the PNM format.
3106 1999-11-07 Federico Mena Quintero <federico@redhat.com>
3108 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation

3118 * src/io-ras.c (image_load): new file from Arjan van de Ven
3119 <arjan@fenrus.demon.nl> to begin the ras loader.
3121 1999-11-05 Federico Mena Quintero <federico@redhat.com>

3156 docs, explain what a dither offset is for.
3157 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3158 this function vs. gdk_pixbuf_render_to_drawable().
3160 1999-11-04 Havoc Pennington <hp@pobox.com>
3162 * configure.in: Use libart-config correctly; find gnome-config
3163 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3166 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3169 Patch untested in the inside-gnome-libs case, I need to commit
3170 then check out to the gnome-libs I'm using.

3237 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
3238 (PixbufPrivate): Renamed need_size_update to need_xform_update.
3239 (recompute_bounding_box): Do not use temporary values.
3241 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3243 * src/io-gif.c (set_gif_lzw_clear_code): new state. Fixes
3246 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): remove
3247 unneeded x,y,h,w vars.
3249 1999-11-03 Larry Ewing <lewing@gimp.org>
3251 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
3252 render_affine calculation for x,y offsets.
3253 (gnome_canvas_pixbuf_set_arg): add x,y args.
3254 (gnome_canvas_pixbuf_get_arg): add x,y args.
3255 (recompute_bounding_box): simply code using ArtDrect and the
3256 render_affine. Removed compute_xform_vectors as it was no longer
3259 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3261 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
3262 doofus. Return a distance, not a boolean, for opaque images.
3264 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
3265 rounding of bounding box coordinates.
3266 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
3267 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
3269 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3271 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
3273 1999-11-03 Michael Fulbright <drmike@redhat.com>
3275 * src/io-jpg.c (image_load_increment): Fixed code which moved
3276 buffer around as new data comes in to work properly. JPEG progressive
3277 loading should be working now except for grayscale JPEG's, which I
3278 will look into next.
3280 1999-11-03 <sopwith@redhat.com>
3281 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
3282 Also put dot printing back in.
3284 1999-11-03 <jrb@redhat.com>
3286 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
3289 1999-11-02 Cody Russell <bratsche@dfw.net>
3290 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
3291 if part of the requested image is offscreen, rather than clipping
3294 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3296 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
3297 for interlacing and progressive loading.
3299 1999-11-02 Cody Russell <bratsche@dfw.net>
3300 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
3301 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
3303 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3305 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
3306 It's a little slow though. )-:
3308 1999-11-02 Elliot Lee <sopwith@redhat.com>
3309 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
3310 write/load_increment operations const-correct.
3312 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3314 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
3315 Implemented the ::point() method. We do a simple containment test
3316 instead of a full distance calculation since the canvas is going
3317 to change to that scheme, anyways.
3319 1999-11-02 Elliot Lee <sopwith@redhat.com>
3321 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
3322 that are read from the input file.
3324 1999-11-02 Larry Ewing <lewing@gimp.org>
3326 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
3328 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
3331 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3333 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3334 affine computation code from ::draw() to here, since it is needed
3335 by ::point() as well.
3337 1999-11-02 Elliot Lee <sopwith@redhat.com>
3339 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3340 three functions, and eliminate duplication of code from write()
3341 and close(). Also fix bug where the 128-byte header was being
3344 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3345 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3346 bounding box computation.
3348 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3350 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3351 Drawing affines seem to work. Bounding box is fubared. ::point()
3352 is not implemented. This is a work in progress.
3354 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3357 * configure.in: Sigh. We need to link in libgnomeui for the
3358 canvas stuff. This mess will disappear when gdk-pixbuf gets
3359 folded into gnome-libs.
3361 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3363 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3364 the right size, at a minimum, even if the image is squished and
3366 (ReadImage): lets get the offset right. This will let transparent
3369 1999-10-29 Michael Fulbright <drmike@redhat.com>
3371 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3372 image width was not a multiple of 4 - always use the
3373 gdk_pixbuf rowstride to increment pointers!
3375 1999-10-29 Michael Fulbright <drmike@redhat.com>
3377 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3378 Currently does not handle either progressive jpeg files (jpeg
3379 files with multiple scans at different quality settings), but
3380 I plan on adding this support soon. These are fairly rare in
3381 my experience, so it shouldn't slow people down too much.
3382 Grayscale jpegs also don't work but that should be easy to fix.
3384 1999-10-29 Michael Fulbright <drmike@redhat.com>
3386 * src/testpixbuf.c: Added title to windows so you can identify
3387 progressive and file windows.
3389 1999-10-29 Michael Fulbright <drmike@redhat.com>
3391 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3392 load the image handler when we determine the image type.
3394 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3395 previously static function load_image_handler () to
3396 a public function gdk_pixbuf_load_module (). It is needed in
3397 gdk-pixbuf-loader.c to load image handler modules. This function
3398 is different from gdk_pixbuf_get_module (), which only returns
3399 a reference to the required handler, because it actually loads
3400 the handler into memory. Both actions should possibly be combined
3401 in a convenience function since one w/o the other doesn't seem to
3404 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3406 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
3409 1999-10-28 Federico Mena Quintero <federico@redhat.com>
3411 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3412 function to render a portion of a pixbuf to a drawable. Ignores
3413 alpha information and takes in a GC.
3414 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3415 portion of a pixbuf to a drawable. It automatically creates a GC
3416 and a clipping mask for alpha pixbufs.
3418 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3420 * src/gdk-pixbuf.h: turned convenience macros into convenience
3421 functions so some error checking could be added.
3423 * src/io-tiff.c (image_load_increment): started work on the tiff
3424 non-incremental loader.
3425 (image_begin_load): Finished the incremental loader.
3427 * src/io-gif.c (image_load_increment): started work on the gif
3430 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
3432 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3434 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3435 function to threshold a pixbuf's alpha channel into a bitmap.
3437 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3438 contemplate future extensions to ArtPixBuf's formats.
3440 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3442 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3443 macros to fetch the ArtPixBuf's fields.
3445 1999-10-27 Havoc Pennington <hp@pobox.com>
3447 * src/testpixbuf.c (main): Display the progressive load
3449 * src/io-png.c (setup_png_transformations): Break transformation
3450 code into separate function
3451 (png_info_callback): Use setup_png_transformations
3453 1999-10-27 Havoc Pennington <hp@pobox.com>
3455 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3456 properly whether the XPM module has already been loaded
3457 (gdk_pixbuf_new_from_file): Check properly if loader module
3458 was already loaded (was checking if load symbol was present
3459 in order to decide whether to re-load; should check module !=
3460 NULL, then load != NULL)
3461 (image_handler_load): Check in present working directory,
3462 makes it easier to debug for now
3463 (file_formats): This array initializer was seriously on crack,
3464 was assigning a function pointer to a GModule*
3466 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
3468 1999-10-27 Havoc Pennington <hp@pobox.com>

3476 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
3477 GdkPixbufLoader, not a GtkObject.
3478 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
3479 (gdk_pixbuf_loader_get_type): Documented.
3480 (gdk_pixbuf_loader_class_init): Initialize the parent class
3482 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
3483 class destroy function.
3484 (gdk_pixbuf_loader_new): Documented.
3485 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3487 (gdk_pixbuf_loader_write): Use size_t for count.
3489 1999-10-27 Michael Fulbright <drmike@redhat.com>
3491 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3492 logic so we only try to close loader if it wasn't previously closed.
3494 1999-10-27 Michael Fulbright <drmike@redhat.com>
3496 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of

3523 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3525 1999-10-22 Havoc Pennington <hp@pobox.com>
3527 * src/io-xpm.c (mem_buffer): Clean up stupid
3528 increment-inside-array-dereference thing
3530 * src/testpixbuf.c: Add XPM data tests.
3532 * src/io-xpm.c: Make the XPM data buffer const, fix const
3533 correctness throughout the code.
3535 1999-10-22 Havoc Pennington <hp@pobox.com>

3545 function, loads pixbuf from xpm data
3546 (image_handler_load): Add g_return_if_fail() to ensure the same
3547 module isn't loaded twice. Add g_module_symbol() to scan for XPM
3550 1999-10-22 Federico Mena Quintero <federico@redhat.com>
3552 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3553 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row

3559 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
3561 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3563 * configure.in: Bumped version number to 0.3.
3565 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool

3574 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
3576 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
3577 terms of the libart functions. Removed the old code.

3580 symbols. Saving will not be implemented in GdkPixbuf.
3582 * src/io-gif.c: Removed the saving stub.
3583 (image_load): Fixed memory management to fail gracefully if we run
3584 out of memory while loading the image. Close the gif file when we
3585 are done. This still needs more error handling for the DGif
3588 * src/io-jpeg.c (image_load): Some robustness fixes.
3590 * src/io-png.c: Removed the saving stuff.
3591 (image_load): Some memory management fixes.

3606 GdkPixBuf to GdkPixbuf, for consistency with the function names
3607 (and it is also easier to type) :-)
3609 1999-10-18 Havoc Pennington <hp@pobox.com>
3611 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
3613 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
3615 1999-10-18 Havoc Pennington <hp@pobox.com>

3623 comment out testpixbuf for now
3625 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3627 * configure.in: Use $GTK_LIBS as the extra libs when checking for
3628 libgif/libungif, as they need the X libraries. Fixes bug #2472.
3630 1999-10-10 Cody Russell <bratsche@dfw.net>
3631 * src/gdk-pixbuf-drawable.c: core function now determines whether
3632 the requested geometry is on screen or not, and if some is not
3633 then the request is clamped to geometry that is on the screen.
3635 Changed 'pixbuf' to 'art_pixbuf' in core function.
3637 1999-10-08 Michael Fulbright <drmike@redhat.com>
3639 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

3646 them, but I wrote them).
3648 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
3651 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
3652 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

3672 * src/io-tiff.c (image_load): ditto + fix leak
3674 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
3675 crashes this module ( add warning :-)
3677 * src/io-bmp.c (image_load): ditto.
3679 * src/io-gif.c (image_load): ditto.
3681 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
3683 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
3684 it doesn't crash scaling with alpha.
3686 1999-09-17 Federico Mena Quintero <federico@redhat.com>
3688 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
3690 * src/io-gif.c (image_load): Likewise.
3692 * src/io-jpeg.c (image_load): Likewise.
3694 * src/io-png.c (image_load): Likewise.

3725 * src/io-png.c (image_save): Added PNG saving function
3727 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's

3745 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3746 calculation needs to be done.
3748 1999-07-18 Larry Ewing <lewing@gimp.org>
3753 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3754 error cases but one or two in the common case. There are probably
3755 a few small ones left.
3757 1999-07-18 Mark Crichton <crichton@gimp.org>
3759 * configure.in: removed version.h.

3780 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3781 loading code so that poeple can diagnose problems better.
3783 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3784 no longer allocates a new pixbuf, which make things nicer for the
3785 rest of the code. Unfortunately there is still a problem with
3786 scaling rgba images.

3790 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3791 calls gdk_pixbuf_scale. However, something is not working.
3792 N.B.: current pixmap is now stored in user_data with a key of
3795 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
3796 Something is still borked, however.

3800 * src/io-jpeg.c (image_load): add raph@gimp.org's fix to the jpeg
3803 * src/testpixbuf.c (main): fix up the file routines a little so
3804 that you can load multiple files given the file names

3808 * src/testpixbuf.c (expose_func): added an almost proper expose
3809 handler for testpixbuf

3813 * configure.in: Fixed GIF check. Replaced " with '
3814 * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale
