405 throughout. Change signatures where necessary to pass the
407 (OneLine16): Fix loading of 16bpp BI_RGB bmps.
408 (DoCompressed): Rewritten to properly support BI_RLE4 and
411 Support for compressed ras images (#84994):

423 (gdk_pixbuf__jpeg_image_load,
424 gdk_pixbuf__jpeg_image_load_increment): Allocate a pixbuf with

433 Thu Jun 13 18:11:11 2002 Owen Taylor <otaylor@redhat.com>
435 * pixops/pixops.c: Fix problem where when no alpha was
436 involved, we scaled rather than composited, but then
437 went ahead and composited anyways. (#76958, Patch
438 from Matthias Clasen). Needs to be merged to GNOME
441 2002-06-13 Matthias Clasen <maclas@gmx.de>
443 * io-jpeg.c: Use libjpeg in buffered-image mode in order to
444 incrementally display incrementally loaded progressive jpegs.
446 2002-06-07 Federico Mena Quintero <federico@ximian.com>
449 (lsb_16): New functions to fetch 32 or 16-bit little-endian values
450 starting at a specific memory location. We do this instead of
451 GINT32_FROM_LE() as the latter is simply dereferences a cast,
452 which doesn't work on platforms with alignment requirements.
455 2002-06-01 Matthias Clasen <maclas@gmx.de>
457 * gdk-pixbuf-io.c (pixbuf_check_xbm): Accept xbms starting

472 2002-05-22 Federico Mena Quintero <federico@ximian.com>
474 * io-xpm.c (pixbuf_create_from_xpm): Ahem, take the rowstride into
475 account!!! Fixes #82515.
477 [This bug is not present in the GNOME 1.4 branch as its XPM loader
478 does not use gdk_pixbuf_new(); rather it malloc()s a buffer with
479 no row padding and then uses gdk_pixbuf_new_from_data() on it.]
481 [IMPORTANT: The comment above is to make my life easier when
482 merging stuff across branches. If you make changes to gdk-pixbuf
483 in either branch, please include a comment in the ChangeLog that
484 indicates whether this should be merged into the other branch.

502 2002-05-07 Michael Natterer <mitch@gimp.org>
504 * gdk-pixbuf/Makefile.am: build the static pixbuf loaders
505 conditionally like the dynamic ones so --without-lib<foo> is
506 honored when building with --disable-modules. (#66867)
508 Sun May 5 02:27:01 2002 Soeren Sandmann <sandmann@daimi.au.dk>
510 * Makefile.am (noinst_PROGRAMS): remove test-loaders (moved to

517 restriction from the description of png tEXt parameters.
519 * io-png.c (png_text_to_pixbuf_option):
520 (gdk_pixbuf__png_image_save): If libpng supports it,
521 store and retrieve non-ISO8859-1 text as UTF-8. (#76172)
523 2002-04-11 Matthias Clasen <maclas@gmx.de>

538 * io-jpeg.c (gdk_pixbuf__jpeg_image_load): Use gdk_pixbuf_new
539 instead of manually allocating image storage.

543 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): Use
544 priv->image_module->module_name instead of image_type which may
547 2002-04-06 Matthias Clasen <maclas@gmx.de>
549 * io-png.c (gdk_pixbuf__png_image_load): Restructured to use
550 gdk_pixbuf_new instead of manually allocating image storage. This
551 gives us a good rowstride and overflow checks. (#77807)
553 2002-04-05 Matthias Clasen <maclas@gmx.de>
555 * io-tiff.c (tiff_image_parse): Avoid allocating an extra copy of

564 2002-03-29 Matthias Clasen <maclas@gmx.de>
566 * io-png.c (png_simple_error_callback): libpng error handlers must
567 not return to their callers, thus longjmp out. This prevents
568 annoying stderr output from the default error handler.
570 2002-03-27 Matthias Clasen <maclas@gmx.de>
572 * io-png.c (gdk_pixbuf__png_image_stop_load): Don't leak info_ptr.
574 * io-png.c (gdk_pixbuf__png_image_load): Get rid of unused
575 end_info. Also call png_read_end to check proper ending of the png
576 file and catch text chunks after the image data.
578 2002-03-27 Matthias Clasen <maclas@gmx.de>
580 * io-png.c (gdk_pixbuf__png_image_load,
581 gdk_pixbuf__png_image_begin_load): Make libpng use g_malloc
582 instead of system malloc.

586 * io-tiff.c (tiff_image_parse): Don't leak pixbuf on error.
588 * io-gif.c (gdk_pixbuf__gif_image_load_increment): Don't leak
589 context->buf on error.
591 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): Make sure to call
592 stop_load even for short images to prevent memleaks.
594 2002-03-25 Matthias Clasen <maclas@gmx.de>
596 * io-png.c (setup_png_transformations): Changed signature to
597 return success and set a GError parameter, adjusted all callers.
598 Also work around a possible FPE in libpng and always check that
599 the new info is sane.
601 2002-03-23 Matthias Clasen <maclas@gmx.de>
603 * io-wbmp.c (gdk_pixbuf__wbmp_image_load_increment):
604 context->updated_func is NULL during a nonincremental load.
605 (gdk_pixbuf__wbmp_image_load): Stop reading after the first error.
607 2002-03-18 Matthias Clasen <maclas@gmx.de>
609 * io-tga.c: Fix assumptions on rowstride by manually allocating a
610 contiguous pixel buffer. Catch buffer overruns in RLE-modi.
611 Support grayscale + alpha (which can be written, but not read (!)
614 2002-03-15 Matthias Clasen <maclas@gmx.de>
616 * io-gif.c (gif_get_frame_info): Catch invalid frame dimensions.
618 2002-03-13 Matthias Clasen <maclas@gmx.de>
620 * test-images.h: Add valid_ras_test and invalid_bmp_1.
622 * test-loaders.c (main): Add random tests for ras and pnm and an
623 invalid bmp which was a crasher until my 2002-03-12 commit.
625 * io-pnm.c (gdk_pixbuf__pnm_image_load_increment): Don't unref the
628 * io-ras.c: Handle some errors.
630 2002-03-12 Sven Neumann <sven@gimp.org>
632 * gdk-pixbuf.c (gdk_pixbuf_fill): use sequential writes instead of
633 calling memcpy(). Simpler and potentially faster. (#70332)
635 2002-03-12 Matthias Clasen <maclas@gmx.de>
637 * io-bmp.c (DecodeHeader): Replace a g_assert_not_reached ()
638 which could actually be reached by a proper error status return.
640 2002-03-05 Matthias Clasen <maclas@gmx.de>
642 * test-loaders.c, test-images.h: More random tests.
644 * io-bmp.c (DecodeHeader): Fail gracefully on OOM here.

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

659 rather than .libs, so we find the right .la files.
661 * test-loaders.c: Back out some accidental commits.
663 Sat Mar 2 21:28:03 2002 Owen Taylor <otaylor@redhat.com>
665 * gdk-pixbuf.c (gdk_pixbuf_new): Bullet-proof against integer

1028 * io-tiff.c (gdk_pixbuf__tiff_image_load): On OSF, apparently fseek()
1029 works in some on-demand way, so the fseek gdk_pixbuf_new_from_file() doesn't
1030 work here since we are using the raw file descriptor. So, we call lseek()
1031 on the fileno(f) before using it. (#60840).

1035 * Makefile.am (gdk-pixbuf-enum-types.c): same change as in pango,
1036 so that flags types are registered as flags rather than enums (not

1087 All of the above from Matthias Clasen <matthiasc@poet.de>,
1088 the remaining from Soeren Sandmann <sandmann@daimi.au.dk>.
1090 * test-images.h: add tests:
1091 - four valid ppm's, eight invalid (matthiasc@poet.de)
1092 - one invalid xpm (matthiasc@poet.de)
1093 - one valid tga, one invalid (sandmann@daimi.au.dk)
1094 - one invalid tiff (sandmann@daimi.au.dk
1096 * test-loaders.c: enable tests for ppm, png, gif, tga, tiff, xpm
1098 * io-tiff.c (gdk_pixbuf__tiff_image_stop_load): TIFFClientOpen can
1099 fail - detect it when it happens
1101 * io-tga.c (gdk_pixbuf__tga_load_increment): Fail if there is too
1104 * gdk-pixbuf-io.c: moved wbmb check after ico check to avoid false
1107 Fri Sep 14 00:30:48 2001 Tim Janik <timj@gtk.org>
1109 * Makefile.am: don't used BUILT_SOURCES to build marshal
1110 files, as in conjunction with stamp files, this can
1111 lead to endless rebuilding loops.
1113 Tue Sep 4 00:22:07 2001 Owen Taylor <otaylor@redhat.com>
1115 * Makefile.am: Fix EXTRA_DIST for gdk-pixbuf-csource.1
1117 Tue Sep 4 03:09:52 2001 Tim Janik <timj@gtk.org>
1119 * gdk-pixbuf-csource.1: new file, manual page for

1141 2001-08-21 Matthias Clasen <matthiasc@poet.de>
1143 * Makefile.am, gdk-pixbuf-io.c, pixbufloader_tga.def,
1144 io-tga.c: Add tga loader, patch by Nicola Girardi. (#56067)
1146 2001-08-20 Matthias Clasen <matthiasc@poet.de>
1148 * test-images.h, test-loaders.c: Add ico and wbmp tests.
1149 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): Fail with a suitable
1150 error if buffer allocation fails.
1151 * io-ico.c: Make .ICO loader more robust.
1152 All of these are due to sandmann@daimi.au.dk (#50187)
1154 2001-08-19 Sven Neumann <sven@gimp.org>
1156 * pixops/pixops.c: applied some simple but effective optimizations
1157 to pixops_composite_nearest() and pixops_composite_color_nearest().
1159 2001-08-07 Sven Neumann <sven@gimp.org>
1161 * gdk-pixbuf.c (gdk_pixbuf_fill): a comment asked to optimize this
1162 function, so that's what I did.
1164 2001-08-06 Kjartan Maraas <kmaraas@gnome.org>
1166 * gdk-pixdata.c: Fix a typo.
1168 2001-07-30 Hans Breuer <hans@breuer.org>

1173 2001-07-20 Hans Breuer <hans@breuer.org>
1175 * gdk-pixdata.c : don't 'g_tohl (*istream++)', but move
1176 pointer increment out of the macro, because at least one
1177 compiler (msvc 5.0) gets confused otherwise (applies the
1180 * gdk_pixbuf.def : updated exports
1182 * makefile.msc : reflect gdk-pixbuf-csource changes

1186 * gdk-pixbuf-csource.c: Add missing <stdlib.h> include.
1187 * io-png.c: (setup_png_transformations): Add ifdef so we compile
1188 without warnings with G_DISABLE_CHECKS on.
1189 * io-pnm.c: (gdk_pixbuf__pnm_image_load_increment): Add a missing
1191 * io-wbmp.c: (getin), (get_mbi): Add a missing const.
1192 * io-xbm.c: (gdk_pixbuf__xbm_image_load_real): Get rid of some
1193 unused locals and add an initial value to quiet the compiler's
1194 unintialized variable warning.
1195 * pixops/pixops.c: Put an ifdef around some dead code.
1197 Thu Jul 5 10:17:15 2001 Owen Taylor <otaylor@redhat.com>
1199 * pixops/Makefile.am (noinst_LTLIBRARIES): Switch
1200 over to the new include flags AC_SUBST(). (Problem
1201 pointed out by Mikael Hermansson.)
1203 2001-06-29 Havoc Pennington <hp@redhat.com>
1205 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init): fix for
1208 Thu Jun 28 21:54:19 2001 Owen Taylor <otaylor@redhat.com>

1211 gdk-pixbuf-csource.c: Fix args to g_type_init ().
1213 2001-06-28 Havoc Pennington <hp@pobox.com>
1215 * gdk-pixdata.c: <string.h>
1217 * gdk-pixbuf-io.c (get_libdir): fix typo in dll name (aren't we
1218 also leaking memory here from g_strdup_printf?)
1220 Tue Jun 26 09:48:02 2001 Tim Janik <timj@gtk.org>
1222 * Makefile.am (noinst_PROGRAMS): get rid of make-inline-pixbuf
1224 * gdk-pixbuf-data.[hc]: provide gdk_pixbuf_new_from_stream()
1225 instead from gdk_pixbuf_new_from_inline().
1227 * gdk-pixdata.[hc]: auxillary GdkPixdata structure, public
1228 installed API for applications that need to serialize/deserialize
1229 on their own (gimp, BEAST).
1231 * gdk-pixbuf/gdk-pixbuf-csource.c: provide publically installed
1232 program that can dump images in CSource format and Pixbuf
1233 stream format. supports RLE encoding, MACRO formatting etc...
1236 Mon Jun 25 00:28:11 2001 Owen Taylor <otaylor@redhat.com>
1238 * Makefile.am: Actually update timestamps, so rules don't
1241 2001-06-11 Havoc Pennington <hp@redhat.com>
1243 * Makefile.am (stamp-gdk-pixbuf-marshal.c): glib_genmarshal
1244 already includes top_builddir
1246 2001-06-08 Havoc Pennington <hp@redhat.com>
1248 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_load_module): remove
1249 bogus g_return_if_fail
1251 * io-gif.c (gif_get_lzw): if delay time is 0 or smaller than
1252 likely timeout resolution, set it to an arbitrarily-chosen short
1254 Fixes bug #55953 from warmenhoven@yahoo.com
1256 2001-06-07 Havoc Pennington <hp@redhat.com>
1258 * Makefile.am: use Owen's new way of doing stampfiles/generated
1261 2001-06-07 Havoc Pennington <hp@redhat.com>

1265 2001-06-05 Havoc Pennington <hp@redhat.com>
1267 * test-loaders.c (main): use putenv not setenv, reported by
1270 2001-05-08 Havoc Pennington <hp@redhat.com>
1272 * gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): docs fixup,
1273 and fix behavior to still subst color if the original image
1276 2001-06-04 Havoc Pennington <hp@redhat.com>
1278 * io-pnm.c (pnm_skip_whitespace): patch from Szekeres Istvan,
1281 2001-06-01 Havoc Pennington <hp@redhat.com>
1283 Apply patch from sandmann@daimi.au.dk, with some tweaks.
1284 Makes things a bit more robust, and adds test-loaders.c
1285 which is good for finding further robustness bugs to fix.
1287 * io-tiff.c: Try to work around libtiff suckiness a bit;
1288 put a giant thread lock on the whole loader,
1289 paranoically check both whether error handlers were called and
1290 also whether functions return false. Handle case where width or
1291 height is 0. Various cleanups.
1293 * io-png.c (gdk_pixbuf__png_image_stop_load): only unref pixbuf
1295 (png_error_callback): apparently libpng expects you to longjmp out
1298 * io-gif.c (struct _GifContext): remove unused "pixbuf" field
1299 (lzw_read_byte): change "Mail jrb if this fails" g_warning
1301 (gif_get_lzw): check for out-of-memory
1302 (gif_prepare_lzw): catch/report an error
1303 (new_context): use try_malloc, since GifContext is nearly 70K
1304 (gdk_pixbuf__gif_image_load_increment): set context->buf to NULL
1305 so we don't crash later.
1307 * Makefile.am: Add test-loaders
1309 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): handle context ==
1312 2001-05-29 Darin Adler <darin@eazel.com>
1314 * gdk-pixbuf.h: Fix prototype to use "(void)" instead of "()".
1316 Mon May 28 14:21:35 2001 Jonathan Blandford <jrb@redhat.com>
1318 * io-bmp.c: Patch from Helmethead <hoshem@mel.comcen.com.au> to
1319 fix up bmp decoder to:
1320 - adds 16 bpp bmp support (bug #53884)
1321 - adds OS/2 1.x format bmp support (bug #54964)
1322 - adds 4 bpp RLE compressed bmp support
1323 - adds 1 bpp colormap support
1324 - fixes negative height (top down) bmp support
1326 2001-05-25 Hans Breuer <hans@breuer.org>
1328 * gdk_pixbuf.def : reflect Havoc's recent api change
1330 Sun May 20 12:53:49 2001 Owen Taylor <otaylor@redhat.com>
1332 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): Remove an
1333 excess $(GLIB_LIBS).
1335 Sun May 13 11:59:11 2001 Owen Taylor <otaylor@redhat.com>
1337 * Makefile.am: Make modules depend on libgdk_pixbuf.la.
1339 2001-05-04 Havoc Pennington <hp@redhat.com>
1341 * pixops/pixops.c (pixops_process): merge fix from stable: Patch
1342 from hoshem@mel.comcen.com.au to fix nonzero X offsets. Fixes
1345 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): merge
1346 from stable: Patch from OKADA Mitsuru <m-okada@fjb.co.jp> to fix
1347 confusion of using "src" instead of "p".
1348 (pixops_composite_color_nearest): Use a more accurate (and
1349 correct, to begin with) compositing method. This cures checks
1350 showing through on images with no alpha.
1352 * gdk-pixbuf.c (gdk_pixbuf_fill): fix bug that left some trailing
1355 * gdk-pixbuf-io.h: fix UpdatedNotifyFunc to use signed ints
1357 * gdk-pixbuf-loader.h (struct _GdkPixbufLoaderClass): Change
1358 area_updated signal to use signed ints. Removed animation-related
1361 * io-gif.c, io-gif-animation.h, io-gif-animation.c: Massive
1364 * gdk-pixbuf-animation.c: Add GdkPixbufAnimationIter to abstract
1365 all the pesky details. Remove old frame-based API. Make
1366 GdkPixbufAnimation an abstract base class, derived by the loaders.
1368 Sun Apr 22 15:51:32 2001 Owen Taylor <otaylor@redhat.com>
1370 * Makefile.am (LDADDS): Add $(MATH_LIB).
1372 2001-04-18 Havoc Pennington <hp@redhat.com>
1374 * gdk-pixbuf.c (gdk_pixbuf_fill): Function to fill pixbuf with a
1377 Wed Apr 4 01:41:02 2001 Tim Janik <timj@gtk.org>
1379 * pixops/Makefile.am (noinst_LTLIBRARIES): include $top_srcdir
1380 so we don't try to get <gtk/gtkobject.h> from standard search
1383 * Makefile.am (gdk-pixbuf-marshal.c): use deps from srcdir.
1384 add gdk-pixbuf-marshal.list to EXTRA_DIST.
1385 take gdk-pixbuf-marshal.h out of _la sources.
1387 2001-03-19 Tor Lillqvist <tml@iki.fi>
1389 * makefile.mingw.in: Handle gdk-pixbuf-marshal.c.
1391 * gdk_pixbuf.def: Update.
1393 * pixbufloader_*.def: Just export the fill_vtable functions now.
1395 2001-03-18 Mike Kestner <mkestner@ameritech.net>
1397 * make-inline-pixbuf.c (main): Added logic to remove output when
1400 2001-03-14 Havoc Pennington <hp@redhat.com>
1402 * Makefile.am (gdk-pixbuf-marshal.c): Use different temporary file
1403 from gdk-pixbuf-marshal.h, fixes parallel makes.
1405 Thu Mar 1 04:01:57 2001 Tim Janik <timj@gtk.org>
1407 * test-gdk-pixbuf.c: fixed includes.
1409 2001-02-18 Havoc Pennington <hp@pobox.com>
1411 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): prepend underscore
1412 (gdk_pixbuf_get_named_module): prepend underscore
1413 (gdk_pixbuf_get_module): prepend underscore
1415 2001-02-19 Havoc Pennington <hp@redhat.com>
1417 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): const fix
1419 2001-02-17 Havoc Pennington <hp@pobox.com>
1421 * gdk-pixbuf-loader.c (gdk_pixbuf_loader_new_with_type): docs
1423 2001-02-07 Alexander Larsson <alexl@redhat.com>
1425 * io-xpm.c (free_buffer):
1426 Use g_free, since the buffer is allocated with g_try_alloc().
1428 2001-02-06 Christophe Merlet <redfox@eikonex.org>
1430 * gdk-pixbuf-data.c: Fixes a minor typo.
1432 Sun Feb 4 07:59:57 2001 Tim Janik <timj@gtk.org>
1434 * gdk-pixbuf.h: DOH! don't include glib/gobject.h but glib-object.h,
1435 we finally need the gobject->gruntime rename.
1437 * *.c: scratched calls to g_type_init(), there's simply no point in
1438 doing that, use gtk_init().
1440 2001-02-01 Havoc Pennington <hp@pobox.com>
1442 * gdk-pixbuf-loader.c, gdk-pixbuf-loader.h: rename "private" field
1443 in struct to "priv" for C++
1445 2001-01-31 Havoc Pennington <hp@pobox.com>
1447 * gdk-pixbuf.c: include glib-object.h instead of gvaluetypes.h
1449 2001-01-26 Havoc Pennington <hp@redhat.com>
1451 * gdk-pixbuf-io.c (mname): fix included modules case.
1453 2001-01-22 Havoc Pennington <hp@redhat.com>
1455 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): check errors
1456 from gdk_pixbuf_load_module
1458 2001-01-22 Havoc Pennington <hp@redhat.com>
1460 * Makefile.am: Add built marshaller files to support
1461 GdkPixbufLoader signals
1463 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): have
1464 GDK_PIXBUF_MODULEDIR unconditionally replace the compiled-in
1465 module location, rather than acting as a fallback, because we are
1466 using GDK_PIXBUF_MODULEDIR to use gdk-pixbuf before installing it.
1468 * gdk-pixbuf.h: include gdk-pixbuf-loader.h
1470 * gdk-pixbuf-loader.h, gdk-pixbuf-loader.c: Move back over here
1471 from gtk, and add error to close(), because stop_load may do
1472 parsing of the image.
1474 * pixops/have_mmx.S (_pixops_have_mmx): add newline at end of file
1476 * io-*.c: make individual operations static, and add fill_vtable
1477 functions which are exported. Fix the collection of type warnings
1478 that surfaced, including a number of functions that didn't
1479 properly take a GError and some that weren't
1480 const-correct. Involved adding error handling for a few loaders.
1482 * gdk-pixbuf-io.h: Add error reporting to stop_load function
1484 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): change to just look up
1485 a function that fills in the GdkPixbufModule vtable, instead of
1486 looking up all the image functions individually; this means we
1487 can get type safety within modules for the loader functions.
1488 Also it means you don't have to keep the statically compiled and
1489 GModule versions in sync.
1491 * test-gdk-pixbuf.c (main): remove gdk_pixbuf_init()
1493 * make-inline-pixbuf.c (main): remove call to gdk_pixbuf_init()
1495 * gdk-pixbuf.h: nuke gdk_pixbuf_init()
1497 * gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_type): g_type_init
1500 * gdk-pixbuf.c (gdk_pixbuf_get_type): g_type_init () here
1502 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_get_type):
1505 2001-01-20 John Harper <jsh@eazel.com>
1507 * io-xbm.c: new pixbuf loader, for X bitmap files. Basically a
1508 collision between Xlib's RdBitF.c and io-tiff.c
1510 * gdk-pixbuf-io.c, Makefile.am, pixbufloader_xbm.def: added
1513 [ merged from stable gdk-pixbuf module. Untested, but it
1514 compiles, and works fine in the stable module ]
1516 2001-01-18 Tor Lillqvist <tml@iki.fi>
1518 * gdk-pixbuf-io.c (get_libdir): (Win32) Use the new
1519 g_win32_get_package_installation_subdirectory() function. No need
1520 to include windows.h.
1521 (gtk_win32_get_installation_directory): Remove this then.
1523 2001-01-01 Havoc Pennington <hp@redhat.com>
1525 * Makefile.am (libgdk_pixbuf_1_3_la_LDFLAGS): add
1526 @LIBTOOL_EXPORT_OPTIONS@
1528 2000-12-30 Tor Lillqvist <tml@iki.fi>
1530 * gdk_pixbuf.def: Update.
1532 2000-12-16 Havoc Pennington <hp@pobox.com>
1534 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): ref
1535 the pixbuf in the frame, so we can use gdk_pixbuf_frame_free
1536 (gdk_pixbuf_frame_copy): new function
1537 (gdk_pixbuf_frame_free): new function
1538 (gdk_pixbuf_frame_get_type): new function
1539 (GDK_TYPE_PIXBUF_FRAME): macro to get type for GdkPixbufFrame
1541 Tue Nov 14 11:51:26 2000 Owen Taylor <otaylor@redhat.com>
1543 * Makefile.am: Add -avoid-version for all modules.
1545 2000-11-13 Havoc Pennington <hp@redhat.com>
1547 * io-png.c (png_simple_error_callback): fix error message to not
1548 say "save" since it's used for loading
1550 2000-11-11 Hans Breuer <Hans@Breuer.Org>
1552 * gdk-pixbuf-io.c : Fix all function prototype macros for self
1553 contained image handlers (!USE_G_MODULE). Files to save should
1554 be opened in binary mode, fopen(s, "wb").
1556 * io-xpm.c : added HAVE_UNISTD_H condition
1558 2000-11-11 Tor Lillqvist <tml@iki.fi>
1560 * gdk_pixbuf.def: Add gdk_pixbuf_new_subpixbuf.
1562 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): Use
1563 g_file_open_tmp() (just added to GLib) instead of mkstemp() (or
1564 mktemp() and open()).
1566 * io-xpm.c (gdk_pixbuf__xpm_image_begin_load): Ditto.
1568 2000-11-01 Havoc Pennington <hp@pobox.com>
1570 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
1571 a pixbuf pointing to a subregion of another pixbuf.
1573 2000-10-16 Tor Lillqvist <tml@iki.fi>
1575 * gdk-pixbuf-io.c: Define also m_save (for the non-gmodule case).
1577 2000-10-16 Havoc Pennington <hp@redhat.com>
1579 * gdk-pixbuf-io.c (gdk_pixbuf_get_module)
1580 (gdk_pixbuf_get_named_module) (gdk_pixbuf_load_module):
1581 add error reporting here also
1583 * make-inline-pixbuf.c (main): use GError

1587 * gdk-pixbuf-util.c: include string.h
1589 * io-*.c: add error reporting
1591 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
1594 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
1596 * gdk-pixbuf-io.h: Add GError** to load_increment and load
1599 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return
1600 a G_FILE_ERROR if we fail to write or close the file.
1602 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
1603 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
1604 the GError naming rules. Add GError** to load functions.
1606 2000-10-06 Havoc Pennington <hp@redhat.com>
1608 * gdk-pixbuf.h: add GdkPixbufAlphaMode
1610 2000-10-06 Havoc Pennington <hp@redhat.com>

1633 (gif_get_next_step): return 0 here, sync from 1.0
1635 * gdk-pixbuf-util.c: sync email address change for Cody
1638 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
1640 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because
1641 last nights code was still "broken". Should now properly handle
1642 all error conditions gracefully.
1644 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
1646 * gdk-pixbuf/io-pnm.c: Rewrote.
1648 2000-09-09 Federico Mena Quintero <federico@helixcode.com>
1650 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute
1651 the correct dest offset.
1653 2000-08-25 Federico Mena Quintero <federico@helixcode.com>
1655 * gdk-pixbuf/io-xpm.c: #include <unistd.h>
1657 2000-08-05 Larry Ewing <lewing@helixcode.com>
1659 * gdk-pixbuf/io-tiff.c: stop leaking context->tempname.
1661 * gdk-pixbuf/io-xpm.c: same as above.
1663 2000-07-26 Michael Meeks <michael@helixcode.com>
1665 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make
1668 2000-07-21 Larry Ewing <lewing@helixcode.com>
1670 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
1671 xpm at least supports the progressive interface like the one in
1672 io-tiff.c. This should be reimplemented as an actual progressive
1675 2000-07-19 Jonathan Blandford <jrb@redhat.com>
1677 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
1678 make it look better.
1679 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael
1680 meeks to handle errors better.
1682 2000-10-07 Tor Lillqvist <tml@iki.fi>
1685 * pixbufloader_jpeg.def
1686 * pixbufloader_png.def: Add new entry points.
1688 * makefile.mingw.in: Use libintl.
1690 2000-10-06 Havoc Pennington <hp@redhat.com>
1692 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
1693 consistent with gdk_pixbuf_loader_new_with_type().
1694 Return runtime error if a module is missing.
1696 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
1698 2000-10-05 Havoc Pennington <hp@redhat.com>
1700 Pixbuf saving, patch from David Welton.
1702 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
1703 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
1705 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf
1707 * io-png.c (gdk_pixbuf__png_image_save): PNG save routine.
1709 * io-jpeg.c (gdk_pixbuf__jpeg_image_save): JPEG save routine.
1711 * gdk-pixbuf-io.c (gdk_pixbuf_save):
1712 (gdk_pixbuf_savev): Implement pixbuf saving routines
1714 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
1717 * gdk-pixbuf.h: Add public save routines; add pixbuf error
1720 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
1722 2000-10-05 Dan Winship <danw@helixcode.com>
1724 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
1725 all three of these files are the JPEG image loader. (From
1728 2000-10-03 Tor Lillqvist <tml@iki.fi>
1730 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
1731 gdk-pixbuf's version number in the rule for makefile.mingw itself.
1733 * gdk_pixbuf.def: Add new entry points.
1735 2000-09-26 Havoc Pennington <hp@redhat.com>
1737 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
1738 function here, instead of putting it in a private GTK+ file.
1740 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
1741 enum here for the known formats of inlined pixbufs.
1742 Also, #define our file magic here.
1744 2000-06-23 Havoc Pennington <hp@redhat.com>
1746 * make-inline-pixbuf.c: Small program that creates C variable
1747 declarations of inline pixbuf data. This can be read
1748 by gdk_pixbuf_new_from_inline.
1750 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
1751 inline pixbuf data and create a pixbuf from it.
1753 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
1755 2000-09-07 Tor Lillqvist <tml@iki.fi>
1757 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
1760 2000-08-12 Tor Lillqvist <tml@iki.fi>
1762 * gdk_pixbuf.def: Add missing entry point.
1764 2000-08-10 Havoc Pennington <hp@redhat.com>
1766 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
1767 (s/pixbuf_/pixbufloader_)
1769 2000-08-02 Tor Lillqvist <tml@iki.fi>
1775 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
1777 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
1778 one. Fix names of DLLs to have '-' instead of '_'.
1780 2000-07-31 Elliot Lee <sopwith@redhat.com>
1781 * io-wbmp.c: Some bug fixes - now tested to work.
1783 2000-07-27 Elliot Lee <sopwith@redhat.com>
1785 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add
1786 gdk_pixbuf_get_named_module() function to facilitate above change
1787 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile:
1788 Implement loader for WBMP format.
1789 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
1791 2000-07-23 Tor Lillqvist <tml@iki.fi>
1796 * pixops/makefile.mingw.in
1797 * pixbuf_*.def: New files.
1800 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
1802 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
1803 New function, to get the GTK+ installation directory from
1804 the Windows Registry, where the installation program
1805 for whatever software includes GTK+ has stored it.
1807 Used to avoid having hardcoding the directory where to look for
1808 loaders. This function is needed by gtk, too, so it should
1809 really be just in one place. Maybe a small static library
1810 one level up from here?
1812 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
1813 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1814 Open file in binary mode. This *is* standard C. (No-op on Unix,
1817 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
1819 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
1820 mktemp() and open().
1821 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
1823 * pixops/*.S: The Gas from mingw32 doesn't like the .type
1824 pseudo-op. Conditionalise on __MINGW32__, but probably
1825 should conditionalise on Gas version instead? Or could we
1826 do without .type on all systems?
1828 * pixops/timescale.c: Use g_get_current_time()
1829 instead of gettimeofday().
1831 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
1833 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
1835 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
1837 * gdk-pixbuf.c: Add <string.h> include.
1839 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
1841 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
1842 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
1843 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
1844 use g_object_new() instead of g_type_create_instance() which
1845 is a private function for fundamental type implementations.
1847 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
1849 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
1850 soname scheme for gdk-pixbuf.
1852 2000-06-21 Havoc Pennington <hp@pobox.com>
1854 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
1855 (i.e. derivation is not allowed, and there are no virtual methods
1857 (gdk_pixbuf_preinit): Call g_type_init() here.
1858 (gdk_pixbuf_init): Add a user-friendly init function, for users
1859 of standalone gdk-pixbuf
1861 * gdk-pixbuf-animation.c: Convert to GObject, in the same
1862 way GdkPixbufAnimation was done.
1864 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
1865 gdk_pixbuf_finalize() from API, since these are broken and don't
1866 make sense with new GObject stuff.
1868 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
1870 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
1871 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
1874 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
1876 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
1877 so I needed something to warm my thighs. Running plain infinite
1878 loops on your laptop to make it hot is not very much fun. A demo
1879 of the gdk-pixbuf scaling functions is way better, and looks
1882 * configure.in (AC_OUTPUT): Added the demo Makefile.
1884 * Makefile.am (SUBDIRS): Added the demo directory.
1886 2000-06-09 Larry Ewing <lewing@helixcode.com>
1888 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
1889 setjmp for the png error handler. It seems setting the error
1890 handling functions does not avoid the jump, and so not calling
1891 setjmp was causing the incremental loader to jump into lala land.
1892 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
1893 not sure this one is actually required but the docs say it must be
1894 set for every call to a png_* function.
1895 Also changed the comment to reflect the fact that setting the
1896 error handlers does _not_ avoid the longjmp.
1898 2000-06-06 Larry Ewing <lewing@helixcode.com>
1900 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
1901 take frame offest into account when trying to calculate the
1902 animation bbox. Also set the width to the width not the height.
1903 (gdk_pixbuf_loader_animation_done): cycle over the frames to
1904 calculate bbox because now we finally have all the offset
1905 information for each frame.
1907 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
1909 * configure.in: add some gtk parameters to the
1910 GDK_PIXBUF_LIBÃ�²S and GDK_PIXBUG_INCLUDEDIR vars. One more
1911 fight in my crusade for strange prefix compile...
1913 2000-05-30 Not Zed <NotZed@HelixCode.com>
1915 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
1916 Initialise the error handler exit routine to our own. Note this
1917 means that every function that accesses the jpeg lib on this
1918 object MUST do a setjmp.
1919 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
1920 lib for handling fatal error.
1921 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
1922 your applications dont quit if there's a jpeg error!
1924 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
1926 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
1927 from Frank de Lange <frank@unternet.org>.
1929 2000-05-09 Darin Adler <darin@eazel.com>
1931 * gdk-pixbuf/test-gdk-pixbuf.c:
1932 Fixed includes to get rid of accidental GNOME dependency.
1934 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
1935 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
1937 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
1939 * configure.in: Bumped version number to 0.8.0.
1941 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
1942 file was not being distributed.
1944 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
1946 2000-05-09 Darin Adler <darin@eazel.com>
1948 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
1949 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
1950 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
1951 formats to 32-bit formats to re-use the high bits of the color values
1952 so that white maps to full white.
1954 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
1956 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
1957 detailed information about the structure and algorithms
1958 of pixops so people can fix it instead of breaking it.
1960 2000-05-04 Darin Adler <darin@eazel.com>
1962 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
1963 (composite_pixel), (composite_line):
1964 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
1965 Now that Owen explained the algorithm, I think I implemented it
1966 right for the cases where the destination pixbuf is not opaque.
1967 The test does seem to confirm it.
1969 2000-05-04 Darin Adler <darin@eazel.com>
1971 * gdk-pixbuf/.cvsignore:
1972 * gdk-pixbuf/Makefile.am:
1973 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
1974 (load_pixel), (simple_composite_test_one),
1975 (simple_composite_test_one_type), (simple_composite_test), (main):
1976 Added some tests of composite to highlight problems in the old
1977 implementation. These tests run without any user interaction.
1978 Just do "make check".
1980 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
1981 (composite_pixel), (composite_line): Fix composite to do a textbook
1982 "A over B" composite. This was clearly the intent, and it was easy
1983 to fix the code to do it. (Note to those that read my earlier tries
1984 at a patch; this version fixes typos that were present in all
1985 my patch attempts. I checked the final version by adding more tests.)
1987 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
1989 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
1990 offset y coordinate accordining to render_y0.
1992 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
1995 2000-04-22 James Henstridge <james@daa.com.au>
1997 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
1998 package to the devel package. The only file installed in bin is
1999 gdk-pixbuf-config, which belongs in -devel. This should allow having
2000 multiple versions of the main gdk-pixbuf package installed.
2002 2000-04-17 Karl Eichwalder <ke@suse.de>
2004 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
2005 Reported by Jens Finke.
2007 2000-04-14 Tomasz KÃ�³opczko <kloczek@pld.org.pl>
2009 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
2010 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
2012 2000-04-13 James Henstridge <james@daa.com.au>
2014 * configure.in: when performing the configure check to see if
2015 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
2016 rather than the other way round. Also, call AC_MSG_RESULT in the
2017 even that dynamic modules were not supported.
2019 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
2021 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
2022 hook to the last unref operation.
2024 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
2025 function to set the last unref handler for a pixbuf.
2026 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
2027 It calls the pixbuf's destroy notification function and frees the
2028 GdkPixbuf structure itself.
2029 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
2032 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
2033 for the last unref handler and its user data.
2035 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
2036 g_new0() to allocate the pixbuf.
2038 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
2039 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
2040 was not specifying the `frame' argument.
2042 * gdk-pixbuf/gdk-pixbuf-animation.c
2043 (gdk_pixbuf_animation_get_width): Fixed docstring.
2044 (gdk_pixbuf_animation_get_height): Likewise.
2045 (gdk_pixbuf_animation_get_num_frames): Likewise.
2046 (gdk_pixbuf_animation_get_frames): Likewise.
2048 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
2051 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
2053 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
2055 * doc/tmpl/refcounting.sgml: Updated with the information about
2056 the last unref handler.
2058 * doc/tmpl/*.sgml: Markup tweaks.
2060 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
2061 update the libtool version number for libgnomecanvaspixbuf as
2063 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
2064 as well, or the old ones won't work with the new stuff. Also,
2065 renamed the modules as follows.
2067 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
2068 modules are called "libpixbufloader-<format>.so" instead of
2069 "libpixbuf-<format>.so". They needed renaming so that the new
2070 loaders won't overwrite the old ones; even with the versioning
2071 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
2074 2000-04-12 Paolo Molaro <lupus@debian.org>
2076 * .cvsignore, src/.cvsignore: shut up cvs.
2078 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
2080 Most of this patch is based on a patch by Havoc Pennington
2081 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
2082 remove the libart dependency.
2084 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
2085 (GdkColorspace): New enum that for now only contains
2087 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
2088 notification function.
2089 (GdkInterpType): New num with interpolation types.
2091 * *.[ch]: Replace the libart stuff with our own stuff.
2093 * pixops/*.[ch]: Likewise.
2095 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
2096 declarations of the GdkPixbuf structures.
2098 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
2100 (gdk_pixbuf_get_format): Constify.
2101 (gdk_pixbuf_get_n_channels): Constify.
2102 (gdk_pixbuf_get_has_alpha): Constify.
2103 (gdk_pixbuf_get_bits_per_sample): Constify.
2104 (gdk_pixbuf_get_pixels): Constify.
2105 (gdk_pixbuf_get_width): Constify.
2106 (gdk_pixbuf_get_height): Constify.
2107 (gdk_pixbuf_get_rowstride): Constify.
2109 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
2112 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
2113 bits_per_sample argument; currently only 8 bits per sample are
2116 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
2118 (gdk_pixbuf_frame_get_x_offset): New accessor.
2119 (gdk_pixbuf_frame_get_y_offset): New accessor.
2120 (gdk_pixbuf_frame_get_delay_time): New accessor.
2121 (gdk_pixbuf_frame_get_action): New accessor.
2123 * gdk-pixbuf/gdk-pixbuf-render.c
2124 (gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
2125 mask rectangle for pixbufs without an alpha channel, set the
2126 *mask_return to NULL.
2128 * gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
2130 * gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
2132 * gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
2133 preconditions. Maybe we should also check for the colorspace,
2134 bits per pixel, and such.
2135 (gdk_pixbuf_composite): Likewise.
2136 (gdk_pixbuf_composite_color): Likewise.
2137 (gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
2138 cannot allocate the new pixbuf.
2139 (gdk_pixbuf_composite_color_simple): Likewise.
2141 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
2142 Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
2145 * gdk-pixbuf/io-bmp.c: Fix includes.
2147 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in

2667 not NULL. Updated inline documentation.
2668 (gdk_pixbuf_animation_ref): New function.
2669 (gdk_pixbuf_animation_unref): New function.
2670 Removed gdk_pixbuf_animation_destroy() in favor of reference
2673 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
2674 Prettified. Made ref_count assertion more paranoid. Check that
2675 the filename is not NULL.
2676 (gdk_pixbuf_get_module): Use guchar * and guint for buffer and
2678 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
2681 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
2682 with a reference count of 1.
2684 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
2685 gdk-pixbuf-animation.c.
2687 * doc/tmpl/animation.sgml: Populated. It is still missing a
2688 description of the overlay modes.
2690 * doc/gdk-pixbuf-sections.txt: Added the animation section. Moved
2691 the canvas item section to the end, as it will be moved later to
2694 * doc/gdk-pixbuf.sgml: Added the animation section.
2696 * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
2698 1999-12-26 Peter Teichman <pat@gnu.org>
2700 * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add
2701 $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker.
2702 This closes bug #4676.
2704 1999-12-23 Havoc Pennington <hp@pobox.com>
2706 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
2707 set to NULL here (specifically context->animation) was not being
2708 set to NULL. use g_new0() to alloc the struct.
2710 1999-12-20 Jonathan Blandford <jrb@redhat.com>
2712 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
2713 correctly. Progressive loading needs some work, but that all
2714 needs doing from the gdk-pixbuf-loader end, not here.
2716 1999-12-17 Jonathan Blandford <jrb@redhat.com>
2718 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
2719 moved the file here. It seems natural to put this function here,
2720 as that's where the gdk_pixbuf_new_from_file function is, but it's
2721 still a little convoluted. The source files might be played with
2724 1999-12-14 Jonathan Blandford <jrb@redhat.com>
2726 * gdk-pixbuf/gdk-pixbuf-loader.c
2727 (gdk_pixbuf_loader_get_animation): Gets the animation from the
2730 1999-12-16 Federico Mena Quintero <federico@redhat.com>
2732 * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
2733 before using the GdkPixbuf rendering functions. Thanks to Joe
2734 Shaw <joe@off.net> for pointing this out.
2736 1999-12-13 Federico Mena Quintero <federico@redhat.com>
2738 * gdk-pixbuf/gnome-canvas-pixbuf.c
2739 (gnome_canvas_pixbuf_class_init): Renamed arguments to
2740 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
2741 consistency with the new canvas.
2742 (PixbufPrivate): Do the same renaming in the structure fields, for
2745 * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.
2747 1999-12-12 Federico Mena Quintero <federico@redhat.com>
2749 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
2750 conditional to see whether to link $(GNOME_LIBS) or not.
2752 1999-12-10 Jonathan Blandford <jrb@redhat.com>
2754 * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API.
2756 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
2757 make a warning go away.
2759 * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations.
2761 * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for
2764 1999-12-09 Michael Zucchi <zucchi@zedzone.mmc.com.au>
2766 * gdk-pixbuf/gdk-pixbuf.h: Enable gdk_pixbuf_get_from_drawable()
2769 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
2770 Filled in body of function.
2771 (rgbconvert): Added GdkColormap parameter, and to all conversion
2773 (convert_real_slow): New function - should convert ANY visual/data
2774 format properly, but it aint fast. Used as a fallback when an
2775 optimised routine wont match.
2776 (rgbconvert): Do very specific tests on the data format to verify
2777 properly if the optimised version will do, otherwise use the
2778 fallback function for all other data formats.
2780 * gdk-pixbuf/Makefile.am: Re-enabled building of
2781 textpixbuf-drawable.
2783 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
2784 gdk_pixbuf_get_from_drawable().
2786 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
2788 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
2789 bug on two occasions.
2790 * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu
2791 function to the generic glib one.
2793 1999-12-08 Federico Mena Quintero <federico@redhat.com>
2795 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
2796 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
2797 checks and API definition. The body needs filling in and it needs
2798 to do the Right Thing(tm) for pixmaps plus the given colormap and
2799 windows and their own colormaps.
2801 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
2802 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
2804 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
2806 * doc/tmpl/from-drawables.sgml: Populated.
2808 * doc/gdk-pixbuf.sgml: Added the from-drawables section.
2810 * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml.
2812 * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs
2815 1999-12-07 Federico Mena Quintero <federico@redhat.com>
2817 * doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about
2818 reference counting for GdkPixbuf structures.
2820 1999-12-07 Martin Baulig <martin@home-of-linux.org>
2822 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
2823 include $(GNOME_LIBS) here.
2825 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2827 Added missing "include <string.h>" to:
2828 * gdk-pixbuf/io-ras.c
2829 * gdk-pixbuf/io-bmp.c
2830 * gdk-pixbuf/io-ico.c
2832 1999-12-06 Federico Mena Quintero <federico@redhat.com>
2834 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
2837 1999-12-05 Federico Mena Quintero <federico@redhat.com>
2839 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
2840 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
2841 want, send me a patch to do the conditional stuff properly.
2842 Otherwise, please read the GNOME Programming Guidelines,
2843 especially the "CVS policies" section.
2845 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
2847 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
2849 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
2851 * gdk-pixbuf/io-ico.c: Bug in palet-size
2854 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
2856 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
2857 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
2859 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
2861 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
2864 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
2865 (Windows Cursor files). These are identical to .ICO files,
2866 except for the signature and 2 extra fields for the hotspot.
2868 1999-12-03 Federico Mena Quintero <federico@redhat.com>
2870 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):
2871 Removed unused variable `item'.
2873 1999-12-03 Jonathan Blandford <jrb@redhat.com>
2875 * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
2876 explain this function better.
2878 1999-12-02 Federico Mena Quintero <federico@redhat.com>
2880 Source files moved from src/ to gdk-pixbuf/, to be consistent with
2883 * doc/Makefile.am: Modified for the new source directory.
2885 * configure.in: Likewise.
2887 * Makefile.am: Likewise.
2889 * autogen.sh: Likewise.
2891 * gdk-pixbuf/Makefile.am: Likewise.
2893 1999-12-02 Federico Mena Quintero <federico@redhat.com>
2895 * src/testpixbuf.c: #include <config.h>, and fix includes.
2897 * src/testpixbuf-drawable.c: #include <config.h>, and fix includes.

2907 * src/io-png.c: Fix includes.
2909 * src/io-ico.c: Fix includes, and do not include more stuff than needed.
2911 * src/io-gif.c: Fix includes, and do not include more stuff than needed.
2913 * src/io-bmp.c: Fix includes, and do not include more stuff than needed.

2921 * src/gdk-pixbuf-render.c: Fix includes.
2923 * src/gdk-pixbuf-io.h: Fix includes.
2925 * src/gdk-pixbuf-drawable.c: Fix includes.
2927 * src/gdk-pixbuf-drawable.h: Use angle brackets for the gdk-pixbuf
2930 * src/gdk-pixbuf-data.c: Fix includes.
2932 * src/gdk-pixbuf-loader.c: #include <config.h>
2934 * src/gdk-pixbuf-loader.h: Use angle brackets for the gdk-pixbuf
2937 * src/Makefile.am: Commented out the gdk-pixbuf-drawable stuff,
2938 since it is not finished.

2942 * src/gdk-pixbuf-util.c: New file with utility and convenience
2943 functions for pixbufs.
2945 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c.
2947 * doc/gdk-pixbuf-sections.txt: Added section for utility functions.
2949 * doc/Makefile.am (tmpl_sources): Added tmpl/util.sgml.
2951 * doc/gdk-pixbuf.sgml: Added the utilities section.
2953 * doc/tmpl/util.sgml: Documentation for the utility functions.
2955 1999-11-29 Owen Taylor <otaylor@redhat.com>
2957 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
2958 Keep the mask around until after we draw ... since
2959 the GC changes aren't flushed to the X server until we
2960 draw, destroying it before that may result in BadPixmap
2963 1999-11-30 Havoc Pennington <hp@pobox.com>
2965 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
2967 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
2969 1999-11-29 Federico Mena Quintero <federico@redhat.com>
2971 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
2972 should be made conditional, not blindly commented out.
2974 1999-11-29 Jonathan Blandford <jrb@redhat.com>
2976 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
2977 handle .ico files. Cool.
2979 1999-11-24 Jonathan Blandford <jrb@redhat.com>
2981 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
2984 1999-11-24 James Henstridge <james@daa.com.au>
2986 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
2987 top builddir rather than src. This still builds fine, and does not
2988 get gtk-doc into an infinite loop when trying to find all the source
2991 1999-11-23 Jonathan Blandford <jrb@redhat.com>
2993 * Removed #PRAGMA } from headers. Also, make compile if you don't
2994 have it installed, already.
2996 1999-11-22 Federico Mena Quintero <federico@redhat.com>
2998 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
2999 temporary buffer to the size of the interesction of the bounding
3000 box and the expose area, not the whole expose area. This speeds
3003 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
3004 not paint black on the mask, since we already cleared it in a
3005 single gdk_draw_rectangle() operation.
3007 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
3009 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
3011 1999-11-22 Havoc Pennington <hp@pobox.com>
3013 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
3014 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
3015 dependencies to LIBADD variables for loadable modules. Necessary
3016 for a Java dynamic loading thing to be able to figure it out.
3018 1999-11-22 Havoc Pennington <hp@pobox.com>
3020 * src/io-png.c (image_load_increment): Call the update_area
3021 callback depending on the number of rows loaded in this increment.
3023 * src/testpixbuf.c (main): slow down the progressive load demo
3025 1999-11-16 Havoc Pennington <hp@pobox.com>
3027 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
3029 1999-11-22 Jonathan Blandford <jrb@redhat.com>
3031 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
3032 for srcdir != buildir != . Beats me why; I can't figure it out.
3033 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
3035 1999-11-21 Jonathan Blandford <jrb@redhat.com>
3037 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
3038 <arjan@fenrus.demon.nl>
3040 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
3042 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
3043 Rework/reorder of the code. Each case has been separated into
3044 another function; its big but it should be quick.
3045 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
3046 opaque alpha information. Not all depths/formats have been
3047 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
3049 1999-11-17 Larry Ewing <lewing@gimp.org>
3051 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
3052 implement the bounds method correctly.
3053 (compute_viewport_affine): compute the affine need to fit the
3054 image within the viewport given by the args.
3055 (compute_render_affine): call compute_viewport_affine.
3057 1999-11-16 Havoc Pennington <hp@pobox.com>
3059 * src/gdk-pixbuf-drawable.h: Use includes from the current
3060 directory, not the system directory.
3062 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
3064 * src/testpixbuf-drawable.c: use includes from the current directory
3065 rather then from the system include directory as gdk-pixbuf
3066 includes are not yet installed when this is compiled.
3068 1999-11-13 Cody Russell <bratsche@dfw.net>
3069 * src/testpixbuf-drawable.c: Added a test program for drawable
3072 * src/Makefile.am: Build testpixbuf-drawable.
3074 1999-11-12 Cody Russell <bratsche@dfw.net>
3076 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.
3078 1999-11-10 Federico Mena Quintero <federico@redhat.com>
3080 * doc/tmpl/gdk-pixbuf-loader.sgml: Populated.
3082 * doc/gdk-pixbuf.signals: Put in the real names of signal
3085 * src/gdk-pixbuf-loader.c: Improved documentation comments.
3087 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3089 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
3092 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
3093 correctly. Patch from Arjan to do so.
3095 1999-11-10 Michael Fulbright <drmike@redhat.com>
3097 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
3100 * src/testpixbuf.c: Added final queued draw when done loading image.
3102 1999-11-10 Jonathan Blandford <jrb@redhat.com>
3104 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
3107 1999-11-10 Federico Mena Quintero <federico@redhat.com>
3109 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
3112 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3114 * src/io-png.c: Fixed some incompatible pointer initializations.
3116 * src/io-jpeg.c (image_load_increment): Remove unused variable.
3118 1999-11-09 Michael Fulbright <drmike@redhat.com>
3120 * src/testpixbuf.c: Fixed it to use timeout to read from file
3121 for progressive loading. Set TBF_KBPS=n, where n is the number of
3122 kilobytes/second to simulate in downloading. n has to be an integer.
3124 * src/io-jpeg.c: Slight cosmetic cleanup.
3126 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
3127 PBM loading has a similar problem and will address tomorrow.
3129 1999-11-09 Havoc Pennington <hp@pobox.com>
3131 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
3132 gdk-pixbuf-drawable stuff.
3134 1999-11-09 Federico Mena Quintero <federico@redhat.com>
3136 * configure.in: Bumped version number to 0.4.
3138 1999-11-09 Michael Fulbright <drmike@redhat.com>
3140 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
3141 all types of PNM files now.
3143 * src/io-jpeg.c (image_load_increment): Figured out problem with
3144 loading Progressive JPEG's progressively (say that 10 times fast).
3145 Currently for Progressive JPEG's the entire image is loaded before
3146 it is displayed. libjpeg supports a fancier mechanism which I may
3149 With these changes all JPEG formats appear to load properly for me.
3151 1999-11-08 Jonathan Blandford <jrb@redhat.com>
3153 * src/io-ras.c (image_load_increment): Final patch from Arjan.
3154 Seems to do progressive loading.
3156 1999-11-08 Michael Fulbright <drmike@redhat.com>
3158 * src/io-pnm.c image_load (): Fixed so we do not create a separate
3159 pixel buffer when reading in image - we reuse the pixel data in
3160 the GdkPixbuf structure instead.
3162 1999-11-08 Michael Fulbright <drmike@redhat.com>
3164 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
3165 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
3166 I can't seem to find a utility to convert into this format.
3167 Next is to add progressive loading support for the PNM format.
3169 1999-11-07 Federico Mena Quintero <federico@redhat.com>
3171 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
3172 of the width, height, x, and y setting and pixels arguments.
3174 1999-11-05 Jonathan Blandford <jrb@redhat.com>
3176 * src/io-ras.c (image_load): third patch. Now it seems to load.
3178 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
3179 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
3181 * src/io-ras.c (image_load): new file from Arjan van de Ven
3182 <arjan@fenrus.demon.nl> to begin the ras loader.
3184 1999-11-05 Federico Mena Quintero <federico@redhat.com>
3186 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
3187 for internal use only.
3189 * doc/gdk-pixbuf.sgml: Likewise.
3191 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
3193 1999-11-05 Michael Fulbright <drmike@redhat.com>
3195 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
3196 files from a file. Next step is support for ASCII files, and
3197 then incremental loading.
3199 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3201 * Makefile.am: Added doc to SUBDIRS.
3203 1999-11-04 Michael Fulbright <drmike@redhat.com>
3205 * src/io-jpeg.c: Prettied up code slightly.
3206 * src/io-pnm.c: Start of pnm loader (from file and progressively).
3207 Doesn't do much yet (will finish tomorrow).
3208 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.
3210 1999-11-04 Federico Mena Quintero <federico@redhat.com>
3212 * doc/tmpl/rendering.sgml: Populated.
3214 * doc/Makefile.am: Added the template files.
3216 1999-11-04 Havoc Pennington <hp@pobox.com>
3218 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): In
3219 docs, explain what a dither offset is for.
3220 (gdk_pixbuf_render_to_drawable_alpha): Explain why you would use
3221 this function vs. gdk_pixbuf_render_to_drawable().
3223 1999-11-04 Havoc Pennington <hp@pobox.com>
3225 * configure.in: Use libart-config correctly; find gnome-config
3226 separately. Fix GNOME_LIBS to be correct in "no gnome installed
3229 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
3232 Patch untested in the inside-gnome-libs case, I need to commit
3233 then check out to the gnome-libs I'm using.
3235 1999-11-04 Michael Fulbright <drmike@redhat.com>
3237 * src/io-jpeg.c (image_begin_load): Add update_func callback.

3273 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3275 * src/io-gif.c (gif_read): renamed ReadOK to gif_read.
3276 Added a lot of comments to the file.
3278 * src/Makefile.am (libpixbuf_gif_la_LIBADD): Remove dependency on
3281 1999-11-03 Michael Fulbright <drmike@redhat.com>
3283 * src/io-jpeg.c (image_load_increment): Further removal of
3284 bugginess in local buffering code. Handles grayscale jpegs
3287 * src/io-jpeg.c (image_load_stop): Was freeing local context
3288 for jpeg library before calling jpeg_decompres_finish ().
3290 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3292 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
3294 (gif_get_lzw): set the transparency to the right val.
3296 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3298 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
3299 Initiailize the x and y fields.
3300 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
3301 (PixbufPrivate): Renamed need_size_update to need_xform_update.
3302 (recompute_bounding_box): Do not use temporary values.
3304 1999-11-03 Jonathan Blandford <jrb@redhat.com>

3312 1999-11-03 Larry Ewing <lewing@gimp.org>
3314 * src/gnome-canvas-pixbuf.c (compute_render_affine): adjust
3315 render_affine calculation for x,y offsets.
3316 (gnome_canvas_pixbuf_set_arg): add x,y args.
3317 (gnome_canvas_pixbuf_get_arg): add x,y args.
3318 (recompute_bounding_box): simply code using ArtDrect and the
3319 render_affine. Removed compute_xform_vectors as it was no longer
3322 1999-11-03 Federico Mena Quintero <federico@redhat.com>
3324 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
3325 doofus. Return a distance, not a boolean, for opaque images.
3327 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
3328 rounding of bounding box coordinates.
3329 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
3330 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
3332 1999-11-03 Jonathan Blandford <jrb@redhat.com>
3334 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
3336 1999-11-03 Michael Fulbright <drmike@redhat.com>
3338 * src/io-jpg.c (image_load_increment): Fixed code which moved
3339 buffer around as new data comes in to work properly. JPEG progressive
3340 loading should be working now except for grayscale JPEG's, which I
3341 will look into next.
3343 1999-11-03 <sopwith@redhat.com>
3344 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
3345 Also put dot printing back in.
3347 1999-11-03 <jrb@redhat.com>
3349 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
3352 1999-11-02 Cody Russell <bratsche@dfw.net>
3353 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
3354 if part of the requested image is offscreen, rather than clipping
3357 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3359 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
3360 for interlacing and progressive loading.
3362 1999-11-02 Cody Russell <bratsche@dfw.net>
3363 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
3364 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
3366 1999-11-02 Jonathan Blandford <jrb@redhat.com>
3368 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
3369 It's a little slow though. )-:
3371 1999-11-02 Elliot Lee <sopwith@redhat.com>
3372 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
3373 write/load_increment operations const-correct.
3375 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3377 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
3378 Implemented the ::point() method. We do a simple containment test
3379 instead of a full distance calculation since the canvas is going
3380 to change to that scheme, anyways.
3382 1999-11-02 Elliot Lee <sopwith@redhat.com>
3384 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
3385 that are read from the input file.
3387 1999-11-02 Larry Ewing <lewing@gimp.org>
3389 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
3391 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
3394 1999-11-02 Federico Mena Quintero <federico@redhat.com>
3396 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
3397 affine computation code from ::draw() to here, since it is needed
3398 by ::point() as well.
3400 1999-11-02 Elliot Lee <sopwith@redhat.com>
3402 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
3403 three functions, and eliminate duplication of code from write()
3404 and close(). Also fix bug where the 128-byte header was being
3407 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3408 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
3409 bounding box computation.
3411 1999-11-01 Federico Mena Quintero <federico@redhat.com>
3413 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
3414 Drawing affines seem to work. Bounding box is fubared. ::point()
3415 is not implemented. This is a work in progress.
3417 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
3420 * configure.in: Sigh. We need to link in libgnomeui for the
3421 canvas stuff. This mess will disappear when gdk-pixbuf gets
3422 folded into gnome-libs.
3424 1999-10-30 Jonathan Blandford <jrb@redhat.com>
3426 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
3427 the right size, at a minimum, even if the image is squished and
3429 (ReadImage): lets get the offset right. This will let transparent
3432 1999-10-29 Michael Fulbright <drmike@redhat.com>
3434 * src/io-jpeg.c: image_load_increment(): Fixed bug when
3435 image width was not a multiple of 4 - always use the
3436 gdk_pixbuf rowstride to increment pointers!
3438 1999-10-29 Michael Fulbright <drmike@redhat.com>
3440 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
3441 Currently does not handle either progressive jpeg files (jpeg
3442 files with multiple scans at different quality settings), but
3443 I plan on adding this support soon. These are fairly rare in
3444 my experience, so it shouldn't slow people down too much.
3445 Grayscale jpegs also don't work but that should be easy to fix.
3447 1999-10-29 Michael Fulbright <drmike@redhat.com>
3449 * src/testpixbuf.c: Added title to windows so you can identify
3450 progressive and file windows.
3452 1999-10-29 Michael Fulbright <drmike@redhat.com>
3454 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
3455 load the image handler when we determine the image type.
3457 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
3458 previously static function load_image_handler () to
3459 a public function gdk_pixbuf_load_module (). It is needed in
3460 gdk-pixbuf-loader.c to load image handler modules. This function
3461 is different from gdk_pixbuf_get_module (), which only returns
3462 a reference to the required handler, because it actually loads
3463 the handler into memory. Both actions should possibly be combined
3464 in a convenience function since one w/o the other doesn't seem to
3467 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3469 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
3472 1999-10-28 Federico Mena Quintero <federico@redhat.com>
3474 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
3475 function to render a portion of a pixbuf to a drawable. Ignores
3476 alpha information and takes in a GC.
3477 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
3478 portion of a pixbuf to a drawable. It automatically creates a GC
3479 and a clipping mask for alpha pixbufs.
3481 1999-10-28 Jonathan Blandford <jrb@redhat.com>
3483 * src/gdk-pixbuf.h: turned convenience macros into convenience
3484 functions so some error checking could be added.
3486 * src/io-tiff.c (image_load_increment): started work on the tiff
3487 non-incremental loader.
3488 (image_begin_load): Finished the incremental loader.
3490 * src/io-gif.c (image_load_increment): started work on the gif
3493 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
3495 1999-10-27 Federico Mena Quintero <federico@redhat.com>
3497 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
3498 function to threshold a pixbuf's alpha channel into a bitmap.
3500 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
3501 contemplate future extensions to ArtPixBuf's formats.
3503 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
3505 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
3506 macros to fetch the ArtPixBuf's fields.
3508 1999-10-27 Havoc Pennington <hp@pobox.com>
3510 * src/testpixbuf.c (main): Display the progressive load
3512 * src/io-png.c (setup_png_transformations): Break transformation
3513 code into separate function
3514 (png_info_callback): Use setup_png_transformations
3516 1999-10-27 Havoc Pennington <hp@pobox.com>
3518 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
3519 properly whether the XPM module has already been loaded
3520 (gdk_pixbuf_new_from_file): Check properly if loader module
3521 was already loaded (was checking if load symbol was present
3522 in order to decide whether to re-load; should check module !=
3523 NULL, then load != NULL)
3524 (image_handler_load): Check in present working directory,
3525 makes it easier to debug for now
3526 (file_formats): This array initializer was seriously on crack,
3527 was assigning a function pointer to a GModule*
3529 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
3531 1999-10-27 Havoc Pennington <hp@pobox.com>

3539 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_new): Return a
3540 GdkPixbufLoader, not a GtkObject.
3541 (gtk_marshal_NONE__INT_INT_INT_INT): Made static.
3542 (gdk_pixbuf_loader_get_type): Documented.
3543 (gdk_pixbuf_loader_class_init): Initialize the parent class
3545 (gdk_pixbuf_loader_destroy): Added sanity checks. Call the parent
3546 class destroy function.
3547 (gdk_pixbuf_loader_new): Documented.
3548 (gdk_pixbuf_loader_finalize): Call the parent class finalize
3550 (gdk_pixbuf_loader_write): Use size_t for count.
3552 1999-10-27 Michael Fulbright <drmike@redhat.com>
3554 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
3555 logic so we only try to close loader if it wasn't previously closed.
3557 1999-10-27 Michael Fulbright <drmike@redhat.com>
3559 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of
3560 pixbuf_loader properly initialized.
3562 * src/testpixbuf.c: Made sure we cleanup pixbuf_loader properly
3565 1999-10-26 Jonathan Blandford <jrb@redhat.com>
3567 * src/gdk-pixbuf-io.c (image_handler_load): load the vtable fully.
3569 * src/gdk-pixbuf-loader.c: Finished initial cut at the object.

3583 1999-10-25 Federico Mena Quintero <federico@redhat.com>
3585 * configure.in (CFLAGS): Patch from Uwe Koloska
3586 <koloska@Rcs1.urz.tu-dresden.de> to fix a stupid typo of mine.
3588 1999-10-22 Havoc Pennington <hp@pobox.com>
3590 * src/io-xpm.c (mem_buffer): Clean up stupid
3591 increment-inside-array-dereference thing
3593 * src/testpixbuf.c: Add XPM data tests.
3595 * src/io-xpm.c: Make the XPM data buffer const, fix const
3596 correctness throughout the code.
3598 1999-10-22 Havoc Pennington <hp@pobox.com>
3600 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()
3602 1999-10-22 Havoc Pennington <hp@pobox.com>
3604 * src/io-xpm.c (image_load_xpm_data): Export this symbol for
3605 loading an XPM from memory.

3608 function, loads pixbuf from xpm data
3609 (image_handler_load): Add g_return_if_fail() to ensure the same
3610 module isn't loaded twice. Add g_module_symbol() to scan for XPM
3613 1999-10-22 Federico Mena Quintero <federico@redhat.com>
3615 * src/io-png.c (image_load): Patch from Kristian Hogsberg
3616 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
3617 buffers; the rows can be read in directly into the main pixel
3620 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3622 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
3624 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3626 * configure.in: Bumped version number to 0.3.
3628 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
3629 version number for the library.
3631 1999-10-20 Federico Mena Quintero <federico@redhat.com>
3633 * src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
3634 all memory management of the buffer is done by libart.
3636 * src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
3637 Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
3639 * src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
3640 terms of the libart functions. Removed the old code.
3642 * src/gdk-pixbuf-io.c (image_handler_load): Removed the save
3643 symbols. Saving will not be implemented in GdkPixbuf.
3645 * src/io-gif.c: Removed the saving stub.
3646 (image_load): Fixed memory management to fail gracefully if we run
3647 out of memory while loading the image. Close the gif file when we
3648 are done. This still needs more error handling for the DGif
3651 * src/io-jpeg.c (image_load): Some robustness fixes.
3653 * src/io-png.c: Removed the saving stuff.
3654 (image_load): Some memory management fixes.

3666 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3668 * src/*: Reindented to use the GNOME Indentation. Renamed
3669 GdkPixBuf to GdkPixbuf, for consistency with the function names
3670 (and it is also easier to type) :-)
3672 1999-10-18 Havoc Pennington <hp@pobox.com>
3674 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
3676 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
3678 1999-10-18 Havoc Pennington <hp@pobox.com>
3680 * Makefile.am (SUBDIRS): Remove "macros"
3682 * configure.in: Don't use GNOME_INIT, handle case where we are
3683 inside gnome-libs. AM_PATH_GTK for the GIF test

3686 comment out testpixbuf for now
3688 1999-10-18 Federico Mena Quintero <federico@redhat.com>
3690 * configure.in: Use $GTK_LIBS as the extra libs when checking for
3691 libgif/libungif, as they need the X libraries. Fixes bug #2472.
3693 1999-10-10 Cody Russell <bratsche@dfw.net>
3694 * src/gdk-pixbuf-drawable.c: core function now determines whether
3695 the requested geometry is on screen or not, and if some is not
3696 then the request is clamped to geometry that is on the screen.
3698 Changed 'pixbuf' to 'art_pixbuf' in core function.
3700 1999-10-08 Michael Fulbright <drmike@redhat.com>
3702 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.
3704 * src/testpifbuf: Changed test program to display cdrom from rgb data
3705 if no filename given to test program.
3707 1999-10-07 Cody Russell <bratsche@dfw.net>
3708 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
3709 them, but I wrote them).
3711 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
3714 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
3715 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.
3717 * src/gdk-pixbuf-drawable.c: Added #include "gdk-pixbuf-drawable.h"
3720 * src/gdk-pixbuf-drawable.[ch]: Changed functions to return
3721 GdkPixBuf* instead of ArtPixBuf*.
3723 1999-09-22 Michael Meeks <michael@nuclecu.unam.mx>
3725 * src/gdk-pixbuf.c (gdk_pixbuf_new): created.
3726 (gdk_pixbuf_scale): use gdk_pixbuf_new + return a new scaled image.
3728 * src/gdk-pixbuf.h (struct _GdkPixBuf): Re-organise struct, + add
3729 GdkPixBufUnrefFunc + gdk_pixbuf_new.
3731 * src/io-jpeg.c (image_load): clean to use gdk_pixbuf_new.
3733 * src/io-xpm.c (_pixbuf_create_from_xpm): ditto.
3735 * src/io-tiff.c (image_load): ditto + fix leak
3737 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
3738 crashes this module ( add warning :-)
3740 * src/io-bmp.c (image_load): ditto.
3742 * src/io-gif.c (image_load): ditto.
3744 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
3746 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
3747 it doesn't crash scaling with alpha.
3749 1999-09-17 Federico Mena Quintero <federico@redhat.com>
3751 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
3753 * src/io-gif.c (image_load): Likewise.
3755 * src/io-jpeg.c (image_load): Likewise.
3757 * src/io-png.c (image_load): Likewise.
3759 * src/io-tiff.c (image_load): Likewise.
3761 * src/io-xpm.c (_pixbuf_create_from_xpm): Likewise.
3763 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_image): Added an assertion
3764 for the ref_count to be != 0.
3766 * src/gdk-pixbuf.c (gdk_pixbuf_ref): Be more paranoid with sanity

3770 1999-08-09 Federico Mena Quintero <federico@nuclecu.unam.mx>
3772 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
3773 to unallocated memory (row_ptr), and fixed its type as well. Take
3774 into account the ArtPixbuf's rowstride when assigning the row
3777 * src/gdk-pixbuf.c: Fixup includes.
3779 * src/gdk-pixbuf-io.c: Likewise.
3781 Sat Jul 31 19:19:47 CEST 1999
3783 * src/gdk-pixbuf-io.c:
3784 * src/io-png.c: Fixed two obvious C syntax bugs
3786 1999-07-29 Mark Crichton <crichton@gimp.org>
3788 * src/io-png.c (image_save): Added PNG saving function
3790 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
3791 image_save(GdkPixBuf *p, FILE *f, ...)
3794 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
3796 * src/Makefile.am (*_LIB): Only build the relevant loaders which
3797 require extra libraries if we actually have those libraries.
3799 1999-07-23 Richard Hestilow <hestgray@ionet.net>
3801 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
3802 * gdk_pixbufConf.sh.in: Added for gnome-config
3804 * configure.in: Modified to generate gdk_pixbufConf.sh
3806 1999-07-20 Mark Crichton <crichton@gimp.org>
3808 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
3809 calculation needs to be done.
3811 1999-07-18 Larry Ewing <lewing@gimp.org>
3816 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
3817 error cases but one or two in the common case. There are probably
3818 a few small ones left.
3820 1999-07-18 Mark Crichton <crichton@gimp.org>
3822 * configure.in: removed version.h.
3824 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
3827 1999-07-17 Mark Crichton <crichton@gimp.org>
3829 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
3830 (gdk_pixbuf_rotate): Added pixbuf rotation code.
3831 (gdk_pixbuf_scale): Changed // comments to /* */
3833 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
3836 1999-07-16 Larry Ewing <lewing@gimp.org>
3838 * src/testpixbuf.c (expose_func): reverted the expose everything
3839 changes, I'm not sure why these went in.
3840 (config_func): bring this up to date with the new pixbuf_scale
3843 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
3844 loading code so that poeple can diagnose problems better.
3846 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
3847 no longer allocates a new pixbuf, which make things nicer for the
3848 rest of the code. Unfortunately there is still a problem with
3849 scaling rgba images.
3851 1999-07-16 Mark Crichton <crichton@gimp.org>
3853 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
3854 calls gdk_pixbuf_scale. However, something is not working.
3855 N.B.: current pixmap is now stored in user_data with a key of
3858 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
3859 Something is still borked, however.
3861 1999-07-15 Larry Ewing <lewing@gimp.org>
3863 * src/io-jpeg.c (image_load): add raph@gimp.org's fix to the jpeg
3866 * src/testpixbuf.c (main): fix up the file routines a little so
3867 that you can load multiple files given the file names
3869 1999-07-14 Larry Ewing <lewing@gimp.org>
3871 * src/testpixbuf.c (expose_func): added an almost proper expose
3872 handler for testpixbuf
3874 1999-07-13 Mark Crichton <crichton@gimp.org>
3876 * configure.in: Fixed GIF check. Replaced " with '
3877 * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale
3879 1999-07-13 Mark Crichton <crichton@gimp.org>
3881 * configure.in: I am a bonehead. Added gif-lib check.
