11 2000-11-01 Havoc Pennington <hp@pobox.com>
13 * gdk-pixbuf.c (gdk_pixbuf_new_subpixbuf): New function to create
14 a pixbuf pointing to a subregion of another pixbuf.
16 2000-10-16 Tor Lillqvist <tml@iki.fi>

30 * gdk-pixbuf-util.c: include string.h
32 * io-*.c: add error reporting
34 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file): add
37 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file): Add error reporting
39 * gdk-pixbuf-io.h: Add GError** to load_increment and load
42 * gdk-pixbuf-io.c (gdk_pixbuf_save) (gdk_pixbuf_savev): return

45 * gdk-pixbuf.h: remove GDK_PIXBUF_ERROR_IO, instead we'll use
46 G_FILE_ERROR_*. Rename enum to GdkPixbufError, properly following
47 the GError naming rules. Add GError** to load functions.
49 2000-10-06 Havoc Pennington <hp@redhat.com>
51 * gdk-pixbuf.h: add GdkPixbufAlphaMode
53 2000-10-06 Havoc Pennington <hp@redhat.com>

81 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com>
83 * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because

85 all error conditions gracefully.
87 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com>
89 * gdk-pixbuf/io-pnm.c: Rewrote.

111 2000-07-21 Larry Ewing <lewing@helixcode.com>
113 * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that
114 xpm at least supports the progressive interface like the one in
115 io-tiff.c. This should be reimplemented as an actual progressive
118 2000-07-19 Jonathan Blandford <jrb@redhat.com>
120 * demo/pixbuf-demo.c (update_timeout): changed scaling level to
122 * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael

133 2000-10-06 Havoc Pennington <hp@redhat.com>
135 * gdk-pixbuf-io.c (gdk_pixbuf_save): s/format/type/g to be
136 consistent with gdk_pixbuf_loader_new_with_type().
137 Return runtime error if a module is missing.
139 * gdk-pixbuf.h: add GDK_PIXBUF_ERROR_UNKNOWN_TYPE
141 2000-10-05 Havoc Pennington <hp@redhat.com>
143 Pixbuf saving, patch from David Welton.
145 * Makefile.am (GDK_PIXBUF_LIBS): add INTLLIBS
146 (libgdk_pixbuf_1_3_la_SOURCES): add gdk-pixbuf-i18n.h
148 * gdk-pixbuf-i18n.h: Add _() to gdk-pixbuf

155 (gdk_pixbuf_savev): Implement pixbuf saving routines
157 * gdk-pixbuf.c (gdk_pixbuf_error_quark): pixbuf error quark
160 * gdk-pixbuf.h: Add public save routines; add pixbuf error
163 * gdk-pixbuf-io.h: Add save function to GdkPixbufModule
165 2000-10-05 Dan Winship <danw@helixcode.com>
167 * io-png.c, io-tiff.c, io-xpm.c: Fix comments to not claim that
168 all three of these files are the JPEG image loader. (From
171 2000-10-03 Tor Lillqvist <tml@iki.fi>
173 * makefile.mingw.in: Add rule for make-inline-pixbuf. Use
174 gdk-pixbuf's version number in the rule for makefile.mingw itself.
176 * gdk_pixbuf.def: Add new entry points.
178 2000-09-26 Havoc Pennington <hp@redhat.com>
180 * gdk-pixbuf-util.c (gdk_pixbuf_saturate_and_pixelate): Add this
181 function here, instead of putting it in a private GTK+ file.
183 * gdk-pixbuf-private.h (GdkPixbufInlineFormat): include an
184 enum here for the known formats of inlined pixbufs.
185 Also, #define our file magic here.
187 2000-06-23 Havoc Pennington <hp@redhat.com>
189 * make-inline-pixbuf.c: Small program that creates C variable
190 declarations of inline pixbuf data. This can be read
191 by gdk_pixbuf_new_from_inline.
193 * gdk-pixbuf.h (gdk_pixbuf_new_from_inline): New function to read
194 inline pixbuf data and create a pixbuf from it.
196 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_inline): implement here
198 2000-09-07 Tor Lillqvist <tml@iki.fi>
200 * makefile.mingw.in: Use own version number for gdk-pixbuf DLLs,
203 2000-08-12 Tor Lillqvist <tml@iki.fi>
205 * gdk_pixbuf.def: Add missing entry point.
207 2000-08-10 Havoc Pennington <hp@redhat.com>
209 * Makefile.am (EXTRA_DIST): The *.def files had the wrong names
210 (s/pixbuf_/pixbufloader_)
212 2000-08-02 Tor Lillqvist <tml@iki.fi>
218 * io-wbmp.c: Conditionalise inclusion of <unistd.h>.
220 * makefile.mingw.in: List loaders alphabetically. Add the wbmp
221 one. Fix names of DLLs to have '-' instead of '_'.
223 2000-07-31 Elliot Lee <sopwith@redhat.com>
224 * io-wbmp.c: Some bug fixes - now tested to work.
226 2000-07-27 Elliot Lee <sopwith@redhat.com>
228 * gdk-pixbuf-io.h, gdk-pixbuf-io.c: Add gdk_pixbuf_get_named_module() function to facilitate above change
229 * io-wbmp.c, pixbufloader_wbmp.defs, gdk-pixbuf-io.c, Makefile: Implement loader for WBMP format.
230 * io-bmp.c: Don't malloc a temporary buffer - use stack instead.
232 2000-07-23 Tor Lillqvist <tml@iki.fi>
237 * pixops/makefile.mingw.in
238 * pixbuf_*.def: New files.
241 * pixops/Makefile.am: Add them. Add rule to generate makefile.mingw.
243 * gdk-pixbuf-io.c (gtk_win32_get_installation_directory):
244 New function, to get the GTK+ installation directory from
245 the Windows Registry, where the installation program
246 for whatever software includes GTK+ has stored it.
248 Used to avoid having hardcoding the directory where to look for
249 loaders. This function is needed by gtk, too, so it should
250 really be just in one place. Maybe a small static library
251 one level up from here?
253 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file)
254 * gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
255 Open file in binary mode. This *is* standard C. (No-op on Unix,
258 * io-jpeg.c: If we don't HAVE_SIGSETJMP, use normal setjmp().
260 * io-tiff.c: Use g_get_tmp_dir(). If we don't HAVE_MKSTEMP, use
262 (gdk_pixbuf__tiff_image_stop_load): g_free() also the tempname.
264 * pixops/*.S: The Gas from mingw32 doesn't like the .type
265 pseudo-op. Conditionalise on __MINGW32__, but probably
266 should conditionalise on Gas version instead? Or could we
267 do without .type on all systems?
269 * pixops/timescale.c: Use g_get_current_time()
270 instead of gettimeofday().
272 Sat Jul 22 10:57:22 2000 Owen Taylor <otaylor@redhat.com>
274 * Makefile.am (test_gdk_pixbuf_LDADD): Remove -lgmodule
276 Tue Jul 11 11:26:42 2000 Owen Taylor <otaylor@redhat.com>
278 * gdk-pixbuf.c: Add <string.h> include.
280 Tue Jul 11 06:20:14 2000 Tim Janik <timj@gtk.org>
282 * io-gif.c (gdk_pixbuf__gif_image_load_animation):
283 * gdk-pixbuf-data.c (gdk_pixbuf_new_from_data):
284 * gdk-pixbuf-animation.c (gdk_pixbuf_animation_new_from_file):
285 use g_object_new() instead of g_type_create_instance() which
286 is a private function for fundamental type implementations.
288 Thu Jul 6 11:49:47 2000 Owen Taylor <otaylor@redhat.com>
290 * Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use GTK+ version
291 soname scheme for gdk-pixbuf.
293 2000-06-21 Havoc Pennington <hp@pobox.com>
295 * gdk-pixbuf.c: Convert GdkPixbuf to GObject, leaving it opaque
296 (i.e. derivation is not allowed, and there are no virtual methods
298 (gdk_pixbuf_preinit): Call g_type_init() here.
299 (gdk_pixbuf_init): Add a user-friendly init function, for users
300 of standalone gdk-pixbuf
302 * gdk-pixbuf-animation.c: Convert to GObject, in the same
303 way GdkPixbufAnimation was done.
305 * gdk-pixbuf.h: Remove gdk_pixbuf_set_unref_handler() and
306 gdk_pixbuf_finalize() from API, since these are broken and don't
307 make sense with new GObject stuff.
309 Wed Jun 21 16:02:48 2000 Owen Taylor <otaylor@redhat.com>
311 * gdk-pixbuf-io.c (gdk_pixbuf_load_module): Add feature to
312 support a GDK_PIXBUF_MODULEDIR env variable as a secondary
315 2000-06-10 Federico Mena Quintero <federico@helixcode.com>
317 * demo/pixbuf-demo.c: It was cold and rainy this Saturday morning,
318 so I needed something to warm my thighs. Running plain infinite
319 loops on your laptop to make it hot is not very much fun. A demo
320 of the gdk-pixbuf scaling functions is way better, and looks
323 * configure.in (AC_OUTPUT): Added the demo Makefile.
325 * Makefile.am (SUBDIRS): Added the demo directory.
327 2000-06-09 Larry Ewing <lewing@helixcode.com>
329 * gdk-pixbuf/io-png.c (gdk_pixbuf__png_image_load_increment):
330 setjmp for the png error handler. It seems setting the error
331 handling functions does not avoid the jump, and so not calling
332 setjmp was causing the incremental loader to jump into lala land.
333 (gdk_pixbuf__png_image_begin_load): setjmp for error handling, I'm
334 not sure this one is actually required but the docs say it must be
335 set for every call to a png_* function.
336 Also changed the comment to reflect the fact that setting the
337 error handlers does _not_ avoid the longjmp.
339 2000-06-06 Larry Ewing <lewing@helixcode.com>
341 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_frame_done):
342 take frame offest into account when trying to calculate the
343 animation bbox. Also set the width to the width not the height.
344 (gdk_pixbuf_loader_animation_done): cycle over the frames to
345 calculate bbox because now we finally have all the offset
346 information for each frame.
348 2000-06-05 Mathieu Lacage <mathieu@gnome.org>
350 * configure.in: add some gtk parameters to the
351 GDK_PIXBUF_LIB²S and GDK_PIXBUG_INCLUDEDIR vars. One more
352 fight in my crusade for strange prefix compile...
354 2000-05-30 Not Zed <NotZed@HelixCode.com>
356 * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_begin_load):
357 Initialise the error handler exit routine to our own. Note this
358 means that every function that accesses the jpeg lib on this
359 object MUST do a setjmp.
360 (gdk_pixbuf__jpeg_image_stop_load): setjmp before accessing jpeg
361 lib for handling fatal error.
362 (gdk_pixbuf__jpeg_image_load_increment): And here too. So now
363 your applications dont quit if there's a jpeg error!
365 2000-05-30 Federico Mena Quintero <federico@helixcode.com>
367 * gdk-pixbuf.spec.in: Include all the loader libraries. Patch
368 from Frank de Lange <frank@unternet.org>.
370 2000-05-09 Darin Adler <darin@eazel.com>
372 * gdk-pixbuf/test-gdk-pixbuf.c:
373 Fixed includes to get rid of accidental GNOME dependency.
375 2000-05-26 Cody Russell <car0969@gamma2.uta.edu>
376 * Makefile.am: Added gdk-pixbuf.spec to EXTRA_DIST
378 2000-05-22 Federico Mena Quintero <federico@helixcode.com>
380 * configure.in: Bumped version number to 0.8.0.
382 * doc/Makefile.am (content_files): The toplevel gdk-pixbuf.sgml
383 file was not being distributed.
385 * gdk-pixbuf/pixops/Makefile.am (EXTRA_DIST): Added DETAILS.
387 2000-05-09 Darin Adler <darin@eazel.com>
389 * gdk-pixbuf/gdk-pixbuf-drawable.c: (rgb565lsb), (rgb565msb),
390 (rgb565alsb), (rgb565amsb), (rgb555lsb), (rgb555msb), (rgb555alsb),
391 (rgb555amsb), (convert_real_slow): Change all conversion from 16-bit
392 formats to 32-bit formats to re-use the high bits of the color values
393 so that white maps to full white.
395 Fri May 5 12:16:32 2000 Owen Taylor <otaylor@redhat.com>
397 * gdk-pixbuf/pixops/DETAILS: Add beginnings of file with
398 detailed information about the structure and algorithms
399 of pixops so people can fix it instead of breaking it.
401 2000-05-04 Darin Adler <darin@eazel.com>
403 * gdk-pixbuf/pixops/pixops.c: (pixops_composite_nearest),
404 (composite_pixel), (composite_line):
405 * gdk-pixbuf/test-gdk-pixbuf.c: (simple_composite_test_one_type):
406 Now that Owen explained the algorithm, I think I implemented it
407 right for the cases where the destination pixbuf is not opaque.
408 The test does seem to confirm it.
410 2000-05-04 Darin Adler <darin@eazel.com>
412 * gdk-pixbuf/.cvsignore:
413 * gdk-pixbuf/Makefile.am:
414 * gdk-pixbuf/test-gdk-pixbuf.c (store_pixel), (fill_with_pixel),
415 (load_pixel), (simple_composite_test_one),
416 (simple_composite_test_one_type), (simple_composite_test), (main):
417 Added some tests of composite to highlight problems in the old
418 implementation. These tests run without any user interaction.
419 Just do "make check".
421 * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest),
422 (composite_pixel), (composite_line): Fix composite to do a textbook
423 "A over B" composite. This was clearly the intent, and it was easy
424 to fix the code to do it. (Note to those that read my earlier tries
425 at a patch; this version fixes typos that were present in all
426 my patch attempts. I checked the final version by adding more tests.)
428 2000-04-22 05:27:43 2000 Owen Taylor <otaylor@redhat.com>
430 * gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Properly
431 offset y coordinate accordining to render_y0.
433 * gdk-pixbuf/gdk-pixbuf-scale.c: Properly handle nonzero
436 2000-04-22 James Henstridge <james@daa.com.au>
438 * gdk-pixbuf.spec.in (%files): moved %{prefix}/bin/* from the main
439 package to the devel package. The only file installed in bin is
440 gdk-pixbuf-config, which belongs in -devel. This should allow having
441 multiple versions of the main gdk-pixbuf package installed.
443 2000-04-17 Karl Eichwalder <ke@suse.de>
445 * gdk-pixbuf/Makefile.am (INCLUDES): Add $(GNOME_CFLAGS).
446 Reported by Jens Finke.
448 2000-04-14 Tomasz K³opczko <kloczek@pld.org.pl>
450 * gdk-pixbuf/pixops/makefile.am: $(LIBART_CFLAGS) replaced by
451 $(GTK_CFLAGS) - now gdk-pixbuf compiles correctly.
453 2000-04-13 James Henstridge <james@daa.com.au>
455 * configure.in: when performing the configure check to see if
456 gmodule works, set CFLAGS to GLIB_CFLAGS and LIBS to GLIB_LIBS,
457 rather than the other way round. Also, call AC_MSG_RESULT in the
458 even that dynamic modules were not supported.
460 2000-04-12 Federico Mena Quintero <federico@helixcode.com>
462 This comes from an excellent idea by Tim Janik (timj@gtk.org) to
463 hook to the last unref operation.
465 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
466 function to set the last unref handler for a pixbuf.
467 (gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
468 It calls the pixbuf's destroy notification function and frees the
469 GdkPixbuf structure itself.
470 (gdk_pixbuf_unref): Use the last unref function of the pixbuf if
473 * gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
474 for the last unref handler and its user data.
476 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
477 g_new0() to allocate the pixbuf.
479 * gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
480 Fixed the call to gtk_signal_new() for the "frame_done" signal; it
481 was not specifying the `frame' argument.
483 * gdk-pixbuf/gdk-pixbuf-animation.c
484 (gdk_pixbuf_animation_get_width): Fixed docstring.
485 (gdk_pixbuf_animation_get_height): Likewise.
486 (gdk_pixbuf_animation_get_num_frames): Likewise.
487 (gdk_pixbuf_animation_get_frames): Likewise.
489 * doc/gdk-pixbuf-sections.txt: Updated with the new functions and
492 * doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
494 * doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
496 * doc/tmpl/refcounting.sgml: Updated with the information about
497 the last unref handler.
499 * doc/tmpl/*.sgml: Markup tweaks.
501 * gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
502 update the libtool version number for libgnomecanvaspixbuf as
504 (libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
505 as well, or the old ones won't work with the new stuff. Also,
506 renamed the modules as follows.
508 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
509 modules are called "libpixbufloader-<format>.so" instead of
510 "libpixbuf-<format>.so". They needed renaming so that the new
511 loaders won't overwrite the old ones; even with the versioning
512 stuff, the new .so symlink to the .so.1.0.0 would overwrite the
515 2000-04-12 Paolo Molaro <lupus@debian.org>
517 * .cvsignore, src/.cvsignore: shut up cvs.
519 2000-04-11 Federico Mena Quintero <federico@helixcode.com>
521 Most of this patch is based on a patch by Havoc Pennington
522 (hp@redhat.com) to make GdkPixbuf's structures opaque and to
523 remove the libart dependency.
525 * gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
526 (GdkColorspace): New enum that for now only contains
528 (GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
529 notification function.
530 (GdkInterpType): New num with interpolation types.
532 * *.[ch]: Replace the libart stuff with our own stuff.
534 * pixops/*.[ch]: Likewise.
536 * gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
537 declarations of the GdkPixbuf structures.
539 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
541 (gdk_pixbuf_get_format): Constify.
542 (gdk_pixbuf_get_n_channels): Constify.
543 (gdk_pixbuf_get_has_alpha): Constify.
544 (gdk_pixbuf_get_bits_per_sample): Constify.
545 (gdk_pixbuf_get_pixels): Constify.
546 (gdk_pixbuf_get_width): Constify.
547 (gdk_pixbuf_get_height): Constify.
548 (gdk_pixbuf_get_rowstride): Constify.
550 * gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
553 * gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
554 bits_per_sample argument; currently only 8 bits per sample are
557 * gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):

1092 2000-01-05 Jonathan Blandford <jrb@redhat.com>
1094 * doc/tmpl/animation.sgml: Documentation changes.
1096 2000-01-01 Federico Mena Quintero <federico@helixcode.com>
1098 * gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
1099 counting to animations. A web browser may want to share a single
1100 copy of an animated GIF if it appears multiple times in a web
1103 * gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
1104 animation functions here.
1105 (gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
1106 animation if the loader does not support multiframe loading and
1107 the single-frame load returned NULL. Check that the filename is
1108 not NULL. Updated inline documentation.
1109 (gdk_pixbuf_animation_ref): New function.
1110 (gdk_pixbuf_animation_unref): New function.
1111 Removed gdk_pixbuf_animation_destroy() in favor of reference
1114 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
1115 Prettified. Made ref_count assertion more paranoid. Check that
1116 the filename is not NULL.
1117 (gdk_pixbuf_get_module): Use guchar * and guint for buffer and
1119 (gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
1122 * gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
1123 with a reference count of 1.
1125 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
1126 gdk-pixbuf-animation.c.
1128 * doc/tmpl/animation.sgml: Populated. It is still missing a
1129 description of the overlay modes.
1131 * doc/gdk-pixbuf-sections.txt: Added the animation section. Moved
1132 the canvas item section to the end, as it will be moved later to
1135 * doc/gdk-pixbuf.sgml: Added the animation section.
1137 * doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
1139 1999-12-26 Peter Teichman <pat@gnu.org>
1141 * gdk-pixbuf/Makefile.am (libpixbuf_tiff_la_LIBADD): add
1142 $(LIBTIFF) to libpixbuf_tiff_la_LIBADD, proxying for mmarker.
1143 This closes bug #4676.
1145 1999-12-23 Havoc Pennington <hp@pobox.com>
1147 * gdk-pixbuf/io-gif.c (image_load): Stuff that should have been
1148 set to NULL here (specifically context->animation) was not being
1149 set to NULL. use g_new0() to alloc the struct.
1151 1999-12-20 Jonathan Blandford <jrb@redhat.com>
1153 * gdk-pixbuf/io-gif.c: finished work to make animated gifs load
1154 correctly. Progressive loading needs some work, but that all
1155 needs doing from the gdk-pixbuf-loader end, not here.
1157 1999-12-17 Jonathan Blandford <jrb@redhat.com>
1159 * gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
1160 moved the file here. It seems natural to put this function here,
1161 as that's where the gdk_pixbuf_new_from_file function is, but it's
1162 still a little convoluted. The source files might be played with
1165 1999-12-14 Jonathan Blandford <jrb@redhat.com>
1167 * gdk-pixbuf/gdk-pixbuf-loader.c
1168 (gdk_pixbuf_loader_get_animation): Gets the animation from the
1171 1999-12-16 Federico Mena Quintero <federico@redhat.com>
1173 * doc/tmpl/rendering.sgml: Added notice about initializing GdkRGB
1174 before using the GdkPixbuf rendering functions. Thanks to Joe
1175 Shaw <joe@off.net> for pointing this out.
1177 1999-12-13 Federico Mena Quintero <federico@redhat.com>
1179 * gdk-pixbuf/gnome-canvas-pixbuf.c
1180 (gnome_canvas_pixbuf_class_init): Renamed arguments to
1181 width_in_pixels, height_in_pixels, x_in_pixels, y_in_pixels, for
1182 consistency with the new canvas.
1183 (PixbufPrivate): Do the same renaming in the structure fields, for
1186 * doc/tmpl/gnome-canvas-pixbuf.sgml: Updated for new argument names.
1188 1999-12-12 Federico Mena Quintero <federico@redhat.com>
1190 * gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Use a
1191 conditional to see whether to link $(GNOME_LIBS) or not.
1193 1999-12-10 Jonathan Blandford <jrb@redhat.com>
1195 * gdk-pixbuf/gdk-pixbuf-io.h: thinking about the new loading API.
1197 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
1198 make a warning go away.
1200 * gdk-pixbuf/gdk-pixbuf.h: added new prototypes for animations.
1202 * gdk-pixbuf/gdk-pixbuf-loader.h: added new prototypes for
1205 1999-12-09 Michael Zucchi <zucchi@zedzone.mmc.com.au>
1207 * gdk-pixbuf/gdk-pixbuf.h: Enable gdk_pixbuf_get_from_drawable()
1210 * gdk-pixbuf/gdk-pixbuf-drawable.c (gdk_pixbuf_get_from_drawable):
1211 Filled in body of function.
1212 (rgbconvert): Added GdkColormap parameter, and to all conversion
1214 (convert_real_slow): New function - should convert ANY visual/data
1215 format properly, but it aint fast. Used as a fallback when an
1216 optimised routine wont match.
1217 (rgbconvert): Do very specific tests on the data format to verify
1218 properly if the optimised version will do, otherwise use the
1219 fallback function for all other data formats.
1221 * gdk-pixbuf/Makefile.am: Re-enabled building of
1222 textpixbuf-drawable.
1224 * gdk-pixbuf/testpixbuf-drawable.c (main): Changed to use
1225 gdk_pixbuf_get_from_drawable().
1227 1999-12-08 Arjan van de Ven <arjan@fenrus.demon.nl>
1229 * gdk-pixbuf/gdk-pixbuf-drawable.c : Fixed the red/green/red
1230 bug on two occasions.
1231 * gdk-pixbuf/io-ras.c: Changed from the custom be32_to_cpu
1232 function to the generic glib one.
1234 1999-12-08 Federico Mena Quintero <federico@redhat.com>
1236 * gdk-pixbuf/gdk-pixbuf-drawable.c: Fix includes.
1237 (gdk_pixbuf_get_from_drawable): Implemented the zillion sanity
1238 checks and API definition. The body needs filling in and it needs
1239 to do the Right Thing(tm) for pixmaps plus the given colormap and
1240 windows and their own colormaps.
1242 * gdk-pixbuf/gdk-pixbuf.h: Added prototype for
1243 gdk_pixbuf_get_from_drawable(). Killed gdk-pixbuf-drawable.h.
1245 * gdk-pixbuf/Makefile.am: Re-added the gdk-pixbuf-drawable sources.
1247 * doc/tmpl/from-drawables.sgml: Populated.
1249 * doc/gdk-pixbuf.sgml: Added the from-drawables section.
1251 * doc/Makefile.am (tmpl_sources): Added tmpl/from-drawables.sgml.
1253 * doc/gdk-pixbuf-sections.txt: Added a section for getting pixbufs
1256 1999-12-07 Federico Mena Quintero <federico@redhat.com>
1258 * doc/tmpl/gnome-canvas-pixbuf.sgml: Added clarification about
1259 reference counting for GdkPixbuf structures.
1261 1999-12-07 Martin Baulig <martin@home-of-linux.org>
1263 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Conditionally
1264 include $(GNOME_LIBS) here.
1266 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
1268 Added missing "include <string.h>" to:
1269 * gdk-pixbuf/io-ras.c
1270 * gdk-pixbuf/io-bmp.c
1271 * gdk-pixbuf/io-ico.c
1273 1999-12-06 Federico Mena Quintero <federico@redhat.com>
1275 * gdk-pixbuf/gdk-pixbuf-io.c (file_formats): Patch from Arjan to
1278 1999-12-05 Federico Mena Quintero <federico@redhat.com>
1280 * gdk-pixbuf/Makefile.am (testpixbuf_LDADD): Add back
1281 $(GNOME_LIBS). This must compile outside of gnome-libs. If you
1282 want, send me a patch to do the conditional stuff properly.
1283 Otherwise, please read the GNOME Programming Guidelines,
1284 especially the "CVS policies" section.
1286 1999-12-05 Jaka Mocnik <jaka.mocnik@kiss.uni-lj.si>
1288 * gdk-pixbuf/Makefile.am: removed GNOME_LIBS from testpixbuf_LDADD.
1290 1999-12-05 Arjan van de Ven <arjan@fenrus.demon.nl>
1292 * gdk-pixbuf/io-ico.c: Bug in palet-size
1295 1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
1297 * gdk-pixbuf/io-bmp.c: Major cleanup, added support for
1298 32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
1300 * gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
1302 * gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
1305 * gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
1306 (Windows Cursor files). These are identical to .ICO files,
1307 except for the signature and 2 extra fields for the hotspot.
1309 1999-12-03 Federico Mena Quintero <federico@redhat.com>
1311 * gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_get_arg):
1312 Removed unused variable `item'.
1314 1999-12-03 Jonathan Blandford <jrb@redhat.com>
1316 * gdk-pixbuf/io-gif.c (gif_fill_in_lines): added a comment to
1317 explain this function better.
1319 1999-12-02 Federico Mena Quintero <federico@redhat.com>
1321 Source files moved from src/ to gdk-pixbuf/, to be consistent with
1324 * doc/Makefile.am: Modified for the new source directory.
1326 * configure.in: Likewise.
1328 * Makefile.am: Likewise.
1330 * autogen.sh: Likewise.
1332 * gdk-pixbuf/Makefile.am: Likewise.
1334 1999-12-02 Federico Mena Quintero <federico@redhat.com>
1336 * src/testpixbuf.c: #include <config.h>, and fix includes.
1338 * src/testpixbuf-drawable.c: #include <config.h>, and fix includes.

1346 * src/io-pnm.c: Fix inlcudes, and do not include more stuff than needed.
1348 * src/io-png.c: Fix includes.
1350 * src/io-ico.c: Fix includes, and do not include more stuff than needed.
1352 * src/io-gif.c: Fix includes, and do not include more stuff than needed.
1354 * src/io-bmp.c: Fix includes, and do not include more stuff than needed.

1362 * src/gdk-pixbuf-render.c: Fix includes.
1364 * src/gdk-pixbuf-io.h: Fix includes.
1366 * src/gdk-pixbuf-drawable.c: Fix includes.
1368 * src/gdk-pixbuf-drawable.h: Use angle brackets for the gdk-pixbuf
1371 * src/gdk-pixbuf-data.c: Fix includes.
1373 * src/gdk-pixbuf-loader.c: #include <config.h>
1375 * src/gdk-pixbuf-loader.h: Use angle brackets for the gdk-pixbuf
1378 * src/Makefile.am: Commented out the gdk-pixbuf-drawable stuff,
1379 since it is not finished.
1381 * src/gdk-pixbuf.h: Removed unused transformation prototypes.
1383 * src/gdk-pixbuf-util.c: New file with utility and convenience
1384 functions for pixbufs.
1386 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): Added gdk-pixbuf-util.c.
1388 * doc/gdk-pixbuf-sections.txt: Added section for utility functions.
1390 * doc/Makefile.am (tmpl_sources): Added tmpl/util.sgml.
1392 * doc/gdk-pixbuf.sgml: Added the utilities section.
1394 * doc/tmpl/util.sgml: Documentation for the utility functions.
1396 1999-11-29 Owen Taylor <otaylor@redhat.com>
1398 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable_alpha):
1399 Keep the mask around until after we draw ... since
1400 the GC changes aren't flushed to the X server until we
1401 draw, destroying it before that may result in BadPixmap
1404 1999-11-30 Havoc Pennington <hp@pobox.com>
1406 * configure.in: Add AM_CONDITIONAL for inside gnome-libs
1408 * src/Makefile.am: conditionalize GnomeCanvasPixbuf
1410 1999-11-29 Federico Mena Quintero <federico@redhat.com>
1412 * src/Makefile.am: Uncomment the GnomeCanvasPixbuf sources. This
1413 should be made conditional, not blindly commented out.
1415 1999-11-29 Jonathan Blandford <jrb@redhat.com>
1417 * src/Makefile.am (ICO_LIB): Added another loader from Arjan to
1418 handle .ico files. Cool.
1420 1999-11-24 Jonathan Blandford <jrb@redhat.com>
1422 * src/io-bmp.c (OneLine24): new patch from Arjan to handle
1425 1999-11-24 James Henstridge <james@daa.com.au>
1427 * configure.in (AC_OUTPUT): altered hack to place the symlink in the
1428 top builddir rather than src. This still builds fine, and does not
1429 get gtk-doc into an infinite loop when trying to find all the source
1432 1999-11-23 Jonathan Blandford <jrb@redhat.com>
1434 * Removed #PRAGMA } from headers. Also, make compile if you don't
1435 have it installed, already.
1437 1999-11-22 Federico Mena Quintero <federico@redhat.com>
1439 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_draw): Create the
1440 temporary buffer to the size of the interesction of the bounding
1441 box and the expose area, not the whole expose area. This speeds
1444 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): Do
1445 not paint black on the mask, since we already cleared it in a
1446 single gdk_draw_rectangle() operation.
1448 1999-11-22 Raja R Harinath <harinath@cs.umn.edu>
1450 * configure.in (GDK_PIXBUF_DIR): Fix for srcdir != builddir.
1452 1999-11-22 Havoc Pennington <hp@pobox.com>
1454 * src/Makefile.am (GDK_PIXBUF_LIBS): Patch from Paul Fisher
1455 <pnfisher@redhat.com> adds all -lgdk-pixbuf and all other
1456 dependencies to LIBADD variables for loadable modules. Necessary
1457 for a Java dynamic loading thing to be able to figure it out.
1459 1999-11-22 Havoc Pennington <hp@pobox.com>
1461 * src/io-png.c (image_load_increment): Call the update_area
1462 callback depending on the number of rows loaded in this increment.
1464 * src/testpixbuf.c (main): slow down the progressive load demo
1466 1999-11-16 Havoc Pennington <hp@pobox.com>
1468 * src/gdk-pixbuf-drawable.h: Get the quotes right on the #include
1470 1999-11-22 Jonathan Blandford <jrb@redhat.com>
1472 * configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
1473 for srcdir != buildir != . Beats me why; I can't figure it out.
1474 AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
1476 1999-11-21 Jonathan Blandford <jrb@redhat.com>
1478 * src/gdk-pixbuf-io.c: added io-bmp from Arjan
1479 <arjan@fenrus.demon.nl>
1481 1999-11-20 Michael Zucchi <zucchi@zedzone.mmc.com.au>
1483 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core):
1484 Rework/reorder of the code. Each case has been separated into
1485 another function; its big but it should be quick.
1486 gdk_pixbuf_rgba_from_drawable() will now return a pixbuf with
1487 opaque alpha information. Not all depths/formats have been
1488 tested, but 8, 15/16 and 24 (alinged 32) should work ok.
1490 1999-11-17 Larry Ewing <lewing@gimp.org>
1492 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_bounds):
1493 implement the bounds method correctly.
1494 (compute_viewport_affine): compute the affine need to fit the
1495 image within the viewport given by the args.
1496 (compute_render_affine): call compute_viewport_affine.
1498 1999-11-16 Havoc Pennington <hp@pobox.com>
1500 * src/gdk-pixbuf-drawable.h: Use includes from the current
1501 directory, not the system directory.
1503 Mon Nov 15 17:18:28 1999 George Lebl <jirka@5z.com>
1505 * src/testpixbuf-drawable.c: use includes from the current directory
1506 rather then from the system include directory as gdk-pixbuf
1507 includes are not yet installed when this is compiled.
1509 1999-11-13 Cody Russell <bratsche@dfw.net>
1510 * src/testpixbuf-drawable.c: Added a test program for drawable
1513 * src/Makefile.am: Build testpixbuf-drawable.
1515 1999-11-12 Cody Russell <bratsche@dfw.net>
1517 * src/gdk-pixbuf-drawable.c: Merged in Michael Zucchi's changes.
1519 1999-11-10 Federico Mena Quintero <federico@redhat.com>
1521 * doc/tmpl/gdk-pixbuf-loader.sgml: Populated.
1523 * doc/gdk-pixbuf.signals: Put in the real names of signal
1526 * src/gdk-pixbuf-loader.c: Improved documentation comments.
1528 1999-11-10 Jonathan Blandford <jrb@redhat.com>
1530 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_close): emit the
1533 * src/io-ras.c (OneLineMapped_file): Now can handle indexing
1534 correctly. Patch from Arjan to do so.
1536 1999-11-10 Michael Fulbright <drmike@redhat.com>
1538 * src/io-pnm.c (pnm_ascii_read_scanline): Fixed loading of ASCII PNM
1541 * src/testpixbuf.c: Added final queued draw when done loading image.
1543 1999-11-10 Jonathan Blandford <jrb@redhat.com>
1545 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_module): removed spurious
1548 1999-11-10 Federico Mena Quintero <federico@redhat.com>
1550 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Added
1553 1999-11-09 Federico Mena Quintero <federico@redhat.com>
1555 * src/io-png.c: Fixed some incompatible pointer initializations.
1557 * src/io-jpeg.c (image_load_increment): Remove unused variable.
1559 1999-11-09 Michael Fulbright <drmike@redhat.com>
1561 * src/testpixbuf.c: Fixed it to use timeout to read from file
1562 for progressive loading. Set TBF_KBPS=n, where n is the number of
1563 kilobytes/second to simulate in downloading. n has to be an integer.
1565 * src/io-jpeg.c: Slight cosmetic cleanup.
1567 * src/io-pnm.c: Fixed raw PNM loading bug. Also discovered that ASCII
1568 PBM loading has a similar problem and will address tomorrow.
1570 1999-11-09 Havoc Pennington <hp@pobox.com>
1572 * src/Makefile.am (libgdk_pixbuf_la_SOURCES): build the
1573 gdk-pixbuf-drawable stuff.
1575 1999-11-09 Federico Mena Quintero <federico@redhat.com>
1577 * configure.in: Bumped version number to 0.4.
1579 1999-11-09 Michael Fulbright <drmike@redhat.com>
1581 * src/io-pnm.c : Finished progressive PNM loading code. Should handle
1582 all types of PNM files now.
1584 * src/io-jpeg.c (image_load_increment): Figured out problem with
1585 loading Progressive JPEG's progressively (say that 10 times fast).
1586 Currently for Progressive JPEG's the entire image is loaded before
1587 it is displayed. libjpeg supports a fancier mechanism which I may
1590 With these changes all JPEG formats appear to load properly for me.
1592 1999-11-08 Jonathan Blandford <jrb@redhat.com>
1594 * src/io-ras.c (image_load_increment): Final patch from Arjan.
1595 Seems to do progressive loading.
1597 1999-11-08 Michael Fulbright <drmike@redhat.com>
1599 * src/io-pnm.c image_load (): Fixed so we do not create a separate
1600 pixel buffer when reading in image - we reuse the pixel data in
1601 the GdkPixbuf structure instead.
1603 1999-11-08 Michael Fulbright <drmike@redhat.com>
1605 * src/io-pnm.c pnm_read_ascii_scanline (): Added support for
1606 ASCII PNM files. Note I haven't tested loaded ASCII PBM files because
1607 I can't seem to find a utility to convert into this format.
1608 Next is to add progressive loading support for the PNM format.
1610 1999-11-07 Federico Mena Quintero <federico@redhat.com>
1612 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished detailed explanation
1613 of the width, height, x, and y setting and pixels arguments.
1615 1999-11-05 Jonathan Blandford <jrb@redhat.com>
1617 * src/io-ras.c (image_load): third patch. Now it seems to load.
1619 * src/gdk-pixbuf-io.c: second patch Arjan van de Ven
1620 <arjan@fenrus.demon.nl> to autodetect/load the sunras files.
1622 * src/io-ras.c (image_load): new file from Arjan van de Ven
1623 <arjan@fenrus.demon.nl> to begin the ras loader.
1625 1999-11-05 Federico Mena Quintero <federico@redhat.com>
1627 * doc/gdk-pixbuf-sections.txt: Removed gdk-pixbuf-io, since it is
1628 for internal use only.
1630 * doc/gdk-pixbuf.sgml: Likewise.
1632 * doc/tmpl/gnome-canvas-pixbuf.sgml: Finished docs.
1634 1999-11-05 Michael Fulbright <drmike@redhat.com>
1636 * src/io-pnm.c: Implemented support for reading raw PBM/PGM/PPM
1637 files from a file. Next step is support for ASCII files, and
1638 then incremental loading.
1640 1999-11-04 Federico Mena Quintero <federico@redhat.com>
1642 * Makefile.am: Added doc to SUBDIRS.
1644 1999-11-04 Michael Fulbright <drmike@redhat.com>
1646 * src/io-jpeg.c: Prettied up code slightly.
1647 * src/io-pnm.c: Start of pnm loader (from file and progressively).
1648 Doesn't do much yet (will finish tomorrow).
1649 * src/gdk-pixbuf-io.c: Added pnm to structure of known types.

1667 separately. Fix GNOME_LIBS to be correct in "no gnome installed
1670 * src/Makefile.am: Link to GNOME_LIBS instead of a hardcoded
1673 Patch untested in the inside-gnome-libs case, I need to commit
1674 then check out to the gnome-libs I'm using.
1676 1999-11-04 Michael Fulbright <drmike@redhat.com>
1678 * src/io-jpeg.c (image_begin_load): Add update_func callback.

1722 1999-11-03 Michael Fulbright <drmike@redhat.com>
1724 * src/io-jpeg.c (image_load_increment): Further removal of
1725 bugginess in local buffering code. Handles grayscale jpegs
1728 * src/io-jpeg.c (image_load_stop): Was freeing local context
1729 for jpeg library before calling jpeg_decompres_finish ().
1731 1999-11-03 Jonathan Blandford <jrb@redhat.com>
1733 * src/io-gif.c (image_load_increment): now handle arbitrary buffer
1735 (gif_get_lzw): set the transparency to the right val.
1737 1999-11-03 Federico Mena Quintero <federico@redhat.com>
1739 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_init):
1740 Initiailize the x and y fields.
1741 (gnome_canvas_pixbuf_destroy): Queue a redraw upon destruction.
1742 (PixbufPrivate): Renamed need_size_update to need_xform_update.

1763 1999-11-03 Federico Mena Quintero <federico@redhat.com>
1765 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point): I'm a
1766 doofus. Return a distance, not a boolean, for opaque images.
1768 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Do proper
1769 rounding of bounding box coordinates.
1770 (gnome_canvas_pixbuf_bounds): Implemented the ::bounds() method.
1771 (gnome_canvas_pixbuf_draw): Use the correct alpha threshold value.
1773 1999-11-03 Jonathan Blandford <jrb@redhat.com>
1775 * src/io-gif.c (gif_prepare_lzw): s/lwz/lzw/g
1777 1999-11-03 Michael Fulbright <drmike@redhat.com>
1779 * src/io-jpg.c (image_load_increment): Fixed code which moved
1780 buffer around as new data comes in to work properly. JPEG progressive
1781 loading should be working now except for grayscale JPEG's, which I
1782 will look into next.
1784 1999-11-03 <sopwith@redhat.com>
1785 * src/testpixbuf.c: A GtkFunction needs to return a value for deterministic behaviour.
1786 Also put dot printing back in.
1788 1999-11-03 <jrb@redhat.com>
1790 * src/io-gif.c (gif_get_extension): Read 'til the next empty block
1793 1999-11-02 Cody Russell <bratsche@dfw.net>
1794 * src/gdk-pixbuf-drawable.c: Changed the behavior to return NULL
1795 if part of the requested image is offscreen, rather than clipping
1798 1999-11-02 Jonathan Blandford <jrb@redhat.com>
1800 * src/io-gif.c (gif_fill_in_lines): Fill in the gif's blank areas
1801 for interlacing and progressive loading.
1803 1999-11-02 Cody Russell <bratsche@dfw.net>
1804 * src/gdk-pixbuf-drawable.c (gdk_pixbuf_from_drawable_core): Now
1805 calls gdk_pixbuf_new_from_art_pixbuf() instead of gdk_pixbuf_new().
1807 1999-11-02 Jonathan Blandford <jrb@redhat.com>
1809 * src/io-gif.c (gif_main_loop): Now progressive gif loading works!
1810 It's a little slow though. )-:
1812 1999-11-02 Elliot Lee <sopwith@redhat.com>
1813 * src/gdk-pixbuf-loader.[ch], src/gdk-pixbuf-io.h: Make the arguments to the
1814 write/load_increment operations const-correct.
1816 1999-11-02 Federico Mena Quintero <federico@redhat.com>
1818 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_point):
1819 Implemented the ::point() method. We do a simple containment test
1820 instead of a full distance calculation since the canvas is going
1821 to change to that scheme, anyways.
1823 1999-11-02 Elliot Lee <sopwith@redhat.com>
1825 * src/testpixbuf.c: Allow using $TBF_READLEN to specify the size of the chunks
1826 that are read from the input file.
1828 1999-11-02 Larry Ewing <lewing@gimp.org>
1830 * src/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render): add aa
1832 (gnome_canvas_pixbuf_class_init): add gnome_canvas_pixbuf_render
1835 1999-11-02 Federico Mena Quintero <federico@redhat.com>
1837 * src/gnome-canvas-pixbuf.c (compute_render_affine): Moved the
1838 affine computation code from ::draw() to here, since it is needed
1839 by ::point() as well.
1841 1999-11-02 Elliot Lee <sopwith@redhat.com>
1843 * src/gdk-pixbuf-loader.c: Reorganize gdk_pixbuf_loader_write into
1844 three functions, and eliminate duplication of code from write()
1845 and close(). Also fix bug where the 128-byte header was being
1848 1999-11-01 Federico Mena Quintero <federico@redhat.com>
1849 * src/gnome-canvas-pixbuf.c (recompute_bounding_box): Fixed
1850 bounding box computation.
1852 1999-11-01 Federico Mena Quintero <federico@redhat.com>
1854 * src/gnome-canvas-pixbuf.c: Start of the pixbuf canvas item.
1855 Drawing affines seem to work. Bounding box is fubared. ::point()
1856 is not implemented. This is a work in progress.
1858 * src/Makefile.am: Added gnome-canvas-pixbuf.[ch] to the list of
1861 * configure.in: Sigh. We need to link in libgnomeui for the
1862 canvas stuff. This mess will disappear when gdk-pixbuf gets
1863 folded into gnome-libs.
1865 1999-10-30 Jonathan Blandford <jrb@redhat.com>
1867 * src/io-gif.c: Some more work. Now it generates a gdk_pixbuf of
1868 the right size, at a minimum, even if the image is squished and
1870 (ReadImage): lets get the offset right. This will let transparent
1873 1999-10-29 Michael Fulbright <drmike@redhat.com>
1875 * src/io-jpeg.c: image_load_increment(): Fixed bug when
1876 image width was not a multiple of 4 - always use the
1877 gdk_pixbuf rowstride to increment pointers!
1879 1999-10-29 Michael Fulbright <drmike@redhat.com>
1881 * src/io-jpeg.c: Added first cut at progressive jpeg loading.
1882 Currently does not handle either progressive jpeg files (jpeg
1883 files with multiple scans at different quality settings), but
1884 I plan on adding this support soon. These are fairly rare in
1885 my experience, so it shouldn't slow people down too much.
1886 Grayscale jpegs also don't work but that should be easy to fix.
1888 1999-10-29 Michael Fulbright <drmike@redhat.com>
1890 * src/testpixbuf.c: Added title to windows so you can identify
1891 progressive and file windows.
1893 1999-10-29 Michael Fulbright <drmike@redhat.com>
1895 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
1896 load the image handler when we determine the image type.
1898 * src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
1899 previously static function load_image_handler () to
1900 a public function gdk_pixbuf_load_module (). It is needed in
1901 gdk-pixbuf-loader.c to load image handler modules. This function
1902 is different from gdk_pixbuf_get_module (), which only returns
1903 a reference to the required handler, because it actually loads
1904 the handler into memory. Both actions should possibly be combined
1905 in a convenience function since one w/o the other doesn't seem to
1908 1999-10-28 Jonathan Blandford <jrb@redhat.com>
1910 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): don't send a
1913 1999-10-28 Federico Mena Quintero <federico@redhat.com>
1915 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_to_drawable): New
1916 function to render a portion of a pixbuf to a drawable. Ignores
1917 alpha information and takes in a GC.
1918 (gdk_pixbuf_render_to_drawable_alpha): New function to render a
1919 portion of a pixbuf to a drawable. It automatically creates a GC
1920 and a clipping mask for alpha pixbufs.
1922 1999-10-28 Jonathan Blandford <jrb@redhat.com>
1924 * src/gdk-pixbuf.h: turned convenience macros into convenience
1925 functions so some error checking could be added.
1927 * src/io-tiff.c (image_load_increment): started work on the tiff
1928 non-incremental loader.
1929 (image_begin_load): Finished the incremental loader.
1931 * src/io-gif.c (image_load_increment): started work on the gif
1934 * src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
1936 1999-10-27 Federico Mena Quintero <federico@redhat.com>
1938 * src/gdk-pixbuf-render.c (gdk_pixbuf_render_threshold_alpha): New
1939 function to threshold a pixbuf's alpha channel into a bitmap.
1941 * src/gdk-pixbuf.c (gdk_pixbuf_new): Fixed so that it will
1942 contemplate future extensions to ArtPixBuf's formats.
1944 * src/io-png.c (png_info_callback): Use the new API of gdk_pixbuf_new().
1946 * src/gdk-pixbuf.h (gdk_pixbuf_get_height): Added some convenience
1947 macros to fetch the ArtPixBuf's fields.
1949 1999-10-27 Havoc Pennington <hp@pobox.com>
1951 * src/testpixbuf.c (main): Display the progressive load
1953 * src/io-png.c (setup_png_transformations): Break transformation
1954 code into separate function
1955 (png_info_callback): Use setup_png_transformations
1957 1999-10-27 Havoc Pennington <hp@pobox.com>
1959 * src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
1960 properly whether the XPM module has already been loaded
1961 (gdk_pixbuf_new_from_file): Check properly if loader module
1962 was already loaded (was checking if load symbol was present
1963 in order to decide whether to re-load; should check module !=
1964 NULL, then load != NULL)
1965 (image_handler_load): Check in present working directory,
1966 makes it easier to debug for now
1967 (file_formats): This array initializer was seriously on crack,
1968 was assigning a function pointer to a GModule*
1970 * src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
1972 1999-10-27 Havoc Pennington <hp@pobox.com>

1987 class destroy function.
1988 (gdk_pixbuf_loader_new): Documented.
1989 (gdk_pixbuf_loader_finalize): Call the parent class finalize
1991 (gdk_pixbuf_loader_write): Use size_t for count.
1993 1999-10-27 Michael Fulbright <drmike@redhat.com>
1995 * src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_destroy): Fixed
1996 logic so we only try to close loader if it wasn't previously closed.
1998 1999-10-27 Michael Fulbright <drmike@redhat.com>
2000 * src/gdk-pixbuf-loader.c: Made sure image_loader struct member of

2029 1999-10-22 Havoc Pennington <hp@pobox.com>
2031 * src/io-xpm.c (mem_buffer): Clean up stupid
2032 increment-inside-array-dereference thing
2034 * src/testpixbuf.c: Add XPM data tests.
2036 * src/io-xpm.c: Make the XPM data buffer const, fix const
2037 correctness throughout the code.
2039 1999-10-22 Havoc Pennington <hp@pobox.com>
2041 * src/gdk-pixbuf.h: Export gdk_pixbuf_new_from_xpm_data()

2056 * src/io-png.c (image_load): Patch from Kristian Hogsberg
2057 Kristensen <hogsberg@daimi.au.dk> to avoid allocating extra row
2058 buffers; the rows can be read in directly into the main pixel
2061 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2063 * src/gdk-pixbuf-io.c (image_handler_load): Free path.
2065 1999-10-20 Federico Mena Quintero <federico@redhat.com>
2067 * configure.in: Bumped version number to 0.3.
2069 * src/Makefile.am (lbgdk_pixbuf_la_LDFLAGS): Added a libtool
2070 version number for the library.
2072 1999-10-20 Federico Mena Quintero <federico@redhat.com>

2084 symbols. Saving will not be implemented in GdkPixbuf.
2086 * src/io-gif.c: Removed the saving stub.
2087 (image_load): Fixed memory management to fail gracefully if we run
2088 out of memory while loading the image. Close the gif file when we
2089 are done. This still needs more error handling for the DGif
2092 * src/io-jpeg.c (image_load): Some robustness fixes.
2094 * src/io-png.c: Removed the saving stuff.
2095 (image_load): Some memory management fixes.

2107 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2109 * src/*: Reindented to use the GNOME Indentation. Renamed
2110 GdkPixBuf to GdkPixbuf, for consistency with the function names
2111 (and it is also easier to type) :-)
2113 1999-10-18 Havoc Pennington <hp@pobox.com>
2115 * configure.in: Use AM_PATH_GLIB instead of glib-config directly
2117 * src/Makefile.am: Re-enable testpixbuf with GTK_CFLAGS/GTK_LIBS
2119 1999-10-18 Havoc Pennington <hp@pobox.com>
2121 * Makefile.am (SUBDIRS): Remove "macros"

2127 comment out testpixbuf for now
2129 1999-10-18 Federico Mena Quintero <federico@redhat.com>
2131 * configure.in: Use $GTK_LIBS as the extra libs when checking for
2132 libgif/libungif, as they need the X libraries. Fixes bug #2472.
2134 1999-10-10 Cody Russell <bratsche@dfw.net>
2135 * src/gdk-pixbuf-drawable.c: core function now determines whether
2136 the requested geometry is on screen or not, and if some is not
2137 then the request is clamped to geometry that is on the screen.
2139 Changed 'pixbuf' to 'art_pixbuf' in core function.
2141 1999-10-08 Michael Fulbright <drmike@redhat.com>
2143 * src/gdk-pixbuf-data.c: Added to load rgb data from const data.

2148 1999-10-07 Cody Russell <bratsche@dfw.net>
2149 * src/gdk-pixbuf-drawable.[ch]: Added. (Actually, Miguel committed
2150 them, but I wrote them).
2152 * src/gdk-pixbuf-drawable.h: Added a missing ; so things will now
2155 * src/Makefile.am: Added gdk-pixbuf-drawable.[ch] to
2156 libgdk_pixbuf_la_SOURCES and libgdk_pixbufinclude_HEADERS.

2170 GdkPixBufUnrefFunc + gdk_pixbuf_new.
2172 * src/io-jpeg.c (image_load): clean to use gdk_pixbuf_new.
2174 * src/io-xpm.c (_pixbuf_create_from_xpm): ditto.
2176 * src/io-tiff.c (image_load): ditto + fix leak
2178 * src/io-png.c (image_load): ditto + add more exit points; monitor.png
2179 crashes this module ( add warning :-)
2181 * src/io-bmp.c (image_load): ditto.
2183 * src/io-gif.c (image_load): ditto.
2185 1999-09-18 Michael Meeks <michael@nuclecu.unam.mx>
2187 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Hack rgba support in so
2188 it doesn't crash scaling with alpha.
2190 1999-09-17 Federico Mena Quintero <federico@redhat.com>
2192 * src/io-bmp.c (image_load): Set the initial ref_count to 1.
2194 * src/io-gif.c (image_load): Likewise.
2196 * src/io-jpeg.c (image_load): Likewise.
2198 * src/io-png.c (image_load): Likewise.

2202 * src/io-xpm.c (_pixbuf_create_from_xpm): Likewise.
2204 * src/gdk-pixbuf-io.c (gdk_pixbuf_load_image): Added an assertion
2205 for the ref_count to be != 0.
2207 * src/gdk-pixbuf.c (gdk_pixbuf_ref): Be more paranoid with sanity
2209 (gdk_pixbuf_unref): Fix incorrect sanity check and comparison.
2211 1999-08-09 Federico Mena Quintero <federico@nuclecu.unam.mx>
2213 * src/io-png.c (image_save): Fixed compiler warnings. Fixed write
2214 to unallocated memory (row_ptr), and fixed its type as well. Take
2215 into account the ArtPixbuf's rowstride when assigning the row
2218 * src/gdk-pixbuf.c: Fixup includes.
2220 * src/gdk-pixbuf-io.c: Likewise.
2222 Sat Jul 31 19:19:47 CEST 1999
2224 * src/gdk-pixbuf-io.c:
2225 * src/io-png.c: Fixed two obvious C syntax bugs
2227 1999-07-29 Mark Crichton <crichton@gimp.org>
2229 * src/io-png.c (image_save): Added PNG saving function
2231 * src/gdk-pixbuf-io.c: Changed image_save function format. Now it's
2232 image_save(GdkPixBuf *p, FILE *f, ...)
2235 1999-07-26 Michael Zucchi <mzucchi@denr.sa.gov.au>
2237 * src/Makefile.am (*_LIB): Only build the relevant loaders which
2238 require extra libraries if we actually have those libraries.
2240 1999-07-23 Richard Hestilow <hestgray@ionet.net>
2242 * src/gdk-pixbuf.h: Include glib.h as it uses g* datatypes
2243 * gdk_pixbufConf.sh.in: Added for gnome-config
2245 * configure.in: Modified to generate gdk_pixbufConf.sh
2247 1999-07-20 Mark Crichton <crichton@gimp.org>
2249 * src/gdk-pixbuf.c (gdk_pixbuf_rotate): Fixed rotation. Now a bbox
2250 calculation needs to be done.
2252 1999-07-18 Larry Ewing <lewing@gimp.org>
2257 * src/io-jpeg.c: Fix a few memory leaks in the, most of them in
2258 error cases but one or two in the common case. There are probably
2259 a few small ones left.
2261 1999-07-18 Mark Crichton <crichton@gimp.org>
2263 * configure.in: removed version.h.
2265 * src/gdk-pixbuf-io.c (pixbuf_check_tiff): Minor readability
2268 1999-07-17 Mark Crichton <crichton@gimp.org>
2270 * src/gdk-pixbuf.c: Removed gdk_pixbuf_free, redundant code.
2271 (gdk_pixbuf_rotate): Added pixbuf rotation code.
2272 (gdk_pixbuf_scale): Changed // comments to /* */
2274 * src/gdk-pixbuf.h (gdk_pixbuf_destroy): Added gdk_pixbuf_destroy
2277 1999-07-16 Larry Ewing <lewing@gimp.org>
2279 * src/testpixbuf.c (expose_func): reverted the expose everything
2280 changes, I'm not sure why these went in.
2281 (config_func): bring this up to date with the new pixbuf_scale
2284 * src/gdk-pixbuf-io.c: added a couple of warnings to the module
2285 loading code so that poeple can diagnose problems better.
2287 * src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
2288 no longer allocates a new pixbuf, which make things nicer for the
2289 rest of the code. Unfortunately there is still a problem with
2290 scaling rgba images.
2292 1999-07-16 Mark Crichton <crichton@gimp.org>
2294 * src/testpixbuf.c (config_func): ConfigureEvent handler. This
2295 calls gdk_pixbuf_scale. However, something is not working.
2296 N.B.: current pixmap is now stored in user_data with a key of
2299 * src/gdk-pixbuf.c (gdk_pixbuf_scale): Implemented scaling function.
2300 Something is still borked, however.
2302 1999-07-15 Larry Ewing <lewing@gimp.org>
2304 * src/io-jpeg.c (image_load): add raph@gimp.org's fix to the jpeg
2307 * src/testpixbuf.c (main): fix up the file routines a little so
2308 that you can load multiple files given the file names
2310 1999-07-14 Larry Ewing <lewing@gimp.org>
2312 * src/testpixbuf.c (expose_func): added an almost proper expose
2313 handler for testpixbuf
2315 1999-07-13 Mark Crichton <crichton@gimp.org>
2317 * configure.in: Fixed GIF check. Replaced " with '
2318 * src/gdk-pixbuf.c: More (minor) work on gdk_pixbuf_scale
2320 1999-07-13 Mark Crichton <crichton@gimp.org>
2322 * configure.in: I am a bonehead. Added gif-lib check.
