This comes from an excellent idea by Tim Janik (timj@gtk.org) to
hook to the last unref operation.
* gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_set_last_unref_handler): New
function to set the last unref handler for a pixbuf.
(gdk_pixbuf_finalize): New function to actually finalize a pixbuf.
It calls the pixbuf's destroy notification function and frees the
GdkPixbuf structure itself.
(gdk_pixbuf_unref): Use the last unref function of the pixbuf if
available.
* gdk-pixbuf/gdk-pixbuf-private.h (struct _GdkPixbuf): New fields
for the last unref handler and its user data.
* gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Use
g_new0() to allocate the pixbuf.
* gdk-pixbuf/gdk-pixbuf-loader.c (gdk_pixbuf_loader_class_init):
Fixed the call to gtk_signal_new() for the "frame_done" signal; it
was not specifying the `frame' argument.
* gdk-pixbuf/gdk-pixbuf-animation.c
(gdk_pixbuf_animation_get_width): Fixed docstring.
(gdk_pixbuf_animation_get_height): Likewise.
(gdk_pixbuf_animation_get_num_frames): Likewise.
(gdk_pixbuf_animation_get_frames): Likewise.
* doc/gdk-pixbuf-sections.txt: Updated with the new functions and
types.
* doc/tmpl/gdk-pixbuf.sgml: Added the description for GdkColorspace.
* doc/tmpl/scaling.sgml: Added the description for GdkInterpType.
* doc/tmpl/refcounting.sgml: Updated with the information about
the last unref handler.
* doc/tmpl/*.sgml: Markup tweaks.
* gdk-pixbuf/Makefile.am (libgnomecanvaspixbuf_la_LDFLAGS): Sigh,
update the libtool version number for libgnomecanvaspixbuf as
well.
(libpixbufloader_*_la_LDFLAGS): The loaders need to be versioned
as well, or the old ones won't work with the new stuff. Also,
renamed the modules as follows.
* gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_load_module): Now the
modules are called "libpixbufloader-<format>.so" instead of
"libpixbuf-<format>.so". They needed renaming so that the new
loaders won't overwrite the old ones; even with the versioning
stuff, the new .so symlink to the .so.1.0.0 would overwrite the
old real .so file.
2000-04-11 Federico Mena Quintero <federico@helixcode.com>
Most of this patch is based on a patch by Havoc Pennington
(hp@redhat.com) to make GdkPixbuf's structures opaque and to
remove the libart dependency.
* gdk-pixbuf/gdk-pixbuf.h: Removed the public structures.
(GdkColorspace): New enum that for now only contains
GDK_COLORSPACE_RGB.
(GdkPixbufDestroyNotify): New type for the pixbuf's pixels destroy
notification function.
(GdkInterpType): New num with interpolation types.
* *.[ch]: Replace the libart stuff with our own stuff.
* pixops/*.[ch]: Likewise.
* gdk-pixbuf/gdk-pixbuf-private.h: New file with the private
declarations of the GdkPixbuf structures.
* gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_new_from_art_pixbuf):
Removed function.
(gdk_pixbuf_get_format): Constify.
(gdk_pixbuf_get_n_channels): Constify.
(gdk_pixbuf_get_has_alpha): Constify.
(gdk_pixbuf_get_bits_per_sample): Constify.
(gdk_pixbuf_get_pixels): Constify.
(gdk_pixbuf_get_width): Constify.
(gdk_pixbuf_get_height): Constify.
(gdk_pixbuf_get_rowstride): Constify.
* gdk-pixbuf/gdk-pixbuf.c (gdk_pixbuf_copy): New function to copy
a pixbuf.
* gdk-pixbuf/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Added a
bits_per_sample argument; currently only 8 bits per sample are
supported.
* gdk-pixbuf/gdk-pixbuf-animation.c (gdk_pixbuf_frame_get_pixbuf):
New accessor.
(gdk_pixbuf_frame_get_x_offset): New accessor.
(gdk_pixbuf_frame_get_y_offset): New accessor.
(gdk_pixbuf_frame_get_delay_time): New accessor.
(gdk_pixbuf_frame_get_action): New accessor.
* gdk-pixbuf/gdk-pixbuf-render.c
(gdk_pixbuf_render_pixmap_and_mask): Instead of returning a solid
mask rectangle for pixbufs without an alpha channel, set the
*mask_return to NULL.
* gdk-pixbuf/gdk-pixbuf-util.c (gdk_pixbuf_add_alpha): Constify.
* gdk-pixbuf/gdk-pixbuf-scale.c: Fix includes.
* gdk-pixbuf/gdk-pixbuf-scale.c (gdk_pixbuf_scale): Added some
preconditions. Maybe we should also check for the colorspace,
bits per pixel, and such.
(gdk_pixbuf_composite): Likewise.
(gdk_pixbuf_composite_color): Likewise.
(gdk_pixbuf_scale_simple): Likewise, and fail gracefully if we
cannot allocate the new pixbuf.
(gdk_pixbuf_composite_color_simple): Likewise.
* gdk-pixbuf/gnome-canvas-pixbuf.c (gnome_canvas_pixbuf_render):
Use art_rgb_rgba_affine() or art_rgb_affine() since we no longer
have an ArtPixBuf.
* gdk-pixbuf/io-bmp.c: Fix includes.
* gdk-pixbuf/pixops/pixops.c (pixops_scale_nearest): Fixed cast in
an lvalue.
* TODO: Populated.

* gdk-pixbuf/Makefile.am: Removed references to libart.
(noinst_HEADERS): Added gdk-pixbuf-private.h.
* gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_LDFLAGS): Incremented
the version number of the libtool library to indicate that this
definitely is not compatible with the old usage. I know you love
me. I know you do.
* configure.in: Bumped version number to 0.7.0.
* README: Updated.
* gdk-pixbuf-config.in (--libs): We no longer require libart.
* DEPENDS.libgdk_pixbuf: We no longer depend on libart.
* gdk-pixbuf.spec.in: Updated, but I don't guarantee anything.
2000-01-01 Federico Mena Quintero <federico@helixcode.com>
* gdk-pixbuf/gdk-pixbuf.h (GdkPixbufAnimation): Added reference
counting to animations. A web browser may want to share a single
copy of an animated GIF if it appears multiple times in a web
page, for example.
* gdk-pixbuf/gdk-pixbuf-animation.c: New file. Moved the
animation functions here.
(gdk_pixbuf_animation_new_from_file): Prettified. Return a NULL
animation if the loader does not support multiframe loading and
the single-frame load returned NULL. Check that the filename is
not NULL. Updated inline documentation.
(gdk_pixbuf_animation_ref): New function.
(gdk_pixbuf_animation_unref): New function.
Removed gdk_pixbuf_animation_destroy() in favor of reference
counting.
* gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_new_from_file):
Prettified. Made ref_count assertion more paranoid. Check that
the filename is not NULL.
(gdk_pixbuf_get_module): Use guchar * and guint for buffer and
size, respectively.
(gdk_pixbuf_new_from_xpm_data): Changed the "data" argument to
const char **.
* gdk-pixbuf/io-gif.c (image_load_animation): Create the animation
with a reference count of 1.
* gdk-pixbuf/Makefile.am (libgdk_pixbuf_la_SOURCES): Added
gdk-pixbuf-animation.c.
* doc/tmpl/animation.sgml: Populated. It is still missing a
description of the overlay modes.
* doc/gdk-pixbuf-sections.txt: Added the animation section. Moved
the canvas item section to the end, as it will be moved later to
gnome-libs.
* doc/gdk-pixbuf.sgml: Added the animation section.
* doc/Makefile.am (tmpl_sources): Added tmpl/animation.sgml.
1999-12-20 Jonathan Blandford <jrb@redhat.com>
* gdk-pixbuf/io-gif.c: finished work to make animated gifs load
correctly. Progressive loading needs some work, but that all
needs doing from the gdk-pixbuf-loader end, not here.
1999-12-17 Jonathan Blandford <jrb@redhat.com>
* gdk-pixbuf/gdk-pixbuf-io.c (gdk_pixbuf_animation_new_from_file):
moved the file here. It seems natural to put this function here,
as that's where the gdk_pixbuf_new_from_file function is, but it's
still a little convoluted. The source files might be played with
in a bit.
1999-12-04 Arjan van de Ven <arjan@fenrus.demon.nl>
* gdk-pixbuf/io-bmp.c: Major cleanup, added support for
32 bpp and 4 bpp (uncompressed) images, fixed 1bpp.
* gdk-pixbuf/io-ras.c: Minor cleanup, ran through lclint
* gdk-pixbuf/io-ico.c: Minor cleanup, fixed 1bpp icons,
ran through lclint.
* gdk-pixbuf/gdk-pixbuf-io.c: Added detection of .CUR files
(Windows Cursor files). These are identical to .ICO files,
except for the signature and 2 extra fields for the hotspot.
1999-11-22 Jonathan Blandford <jrb@redhat.com>
* configure.in (GDK_PIXBUF_DIR): make the symlink. Does not work
for srcdir != buildir != . Beats me why; I can't figure it out.
AC_OUTPUT_COMMANDS doesn't seem to let me substitute it correctly.
1999-11-10 Federico Mena Quintero <federico@redhat.com>
* doc/tmpl/gdk-pixbuf-loader.sgml: Populated.
* doc/gdk-pixbuf.signals: Put in the real names of signal
arguments.
* src/gdk-pixbuf-loader.c: Improved documentation comments.
1999-11-05 Jonathan Blandford <jrb@redhat.com>
* src/gdk-pixbuf-io.c: second patch Arjan van de Ven
<arjan@fenrus.demon.nl> to autodetect/load the sunras files.
999-11-04 Michael Fulbright <drmike@redhat.com>
* src/io-jpeg.c: Prettied up code slightly.
* src/io-pnm.c: Start of pnm loader (from file and progressively).
Doesn't do much yet (will finish tomorrow).
* src/gdk-pixbuf-io.c: Added pnm to structure of known types.
1999-10-29 Michael Fulbright <drmike@redhat.com>
* src/gdk-pixbuf-loader.c (gdk_pixbuf_loader_write): Actually
load the image handler when we determine the image type.
* src/gdk-pixbuf-io.[ch] (gdk_pixbuf_load_module): Changed the
previously static function load_image_handler () to
a public function gdk_pixbuf_load_module (). It is needed in
gdk-pixbuf-loader.c to load image handler modules. This function
is different from gdk_pixbuf_get_module (), which only returns
a reference to the required handler, because it actually loads
the handler into memory. Both actions should possibly be combined
in a convenience function since one w/o the other doesn't seem to
make much sense.
1999-10-28 Jonathan Blandford <jrb@redhat.com>
* src/io-tiff.c (image_load_increment): started work on the tiff
non-incremental loader.
* src/io-gif.c (image_load_increment): started work on the gif
incremental loader.
* src/gdk-pixbuf-io.h: Changed ModuleType to GdkPixbufModule.
1999-10-27 Havoc Pennington <hp@pobox.com>
* src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): Check
properly whether the XPM module has already been loaded
(gdk_pixbuf_new_from_file): Check properly if loader module
was already loaded (was checking if load symbol was present
in order to decide whether to re-load; should check module !=
NULL, then load != NULL)
(image_handler_load): Check in present working directory,
makes it easier to debug for now
(file_formats): This array initializer was seriously on crack,
was assigning a function pointer to a GModule*
* src/testpixbuf.c (main): Change type of pixbuf_loader to GdkPixbufLoader*
* src/io-png.c: Progressive loading stuff compiles, untested.
1999-10-22 Havoc Pennington <hp@pobox.com>
* src/io-xpm.c (image_load_xpm_data): Export this symbol for
loading an XPM from memory.
* src/gdk-pixbuf-io.c (gdk_pixbuf_new_from_xpm_data): New
function, loads pixbuf from xpm data
(image_handler_load): Add g_return_if_fail() to ensure the same
module isn't loaded twice. Add g_module_symbol() to scan for XPM
loader function.
1999-10-20 Federico Mena Quintero <federico@redhat.com>
* src/gdk-pixbuf.h (GdkPixbuf): Removed the unref_fn field. Now
all memory management of the buffer is done by libart.
* src/gdk-pixbuf.c (gdk_pixbuf_unref): Do destruction here.
Removed gdk_pixbuf_destroy, gdk_pixbuf_duplicate.
* src/gdk-pixbuf-data.c (gdk_pixbuf_new_from_data): Implemented in
terms of the libart functions. Removed the old code.
* src/gdk-pixbuf-io.c (image_handler_load): Removed the save
symbols. Saving will not be implemented in GdkPixbuf.
* src/io-gif.c: Removed the saving stub.
(image_load): Fixed memory management to fail gracefully if we run
out of memory while loading the image. Close the gif file when we
are done. This still needs more error handling for the DGif
functions.
* src/io-jpeg.c (image_load): Some robustness fixes.
* src/io-png.c: Removed the saving stuff.
(image_load): Some memory management fixes.
* src/io-tiff.c (image_load): Ditto.
* src/io-xpm.c (pixbuf_create_from_xpm): Ditto.
1999-08-09 Federico Mena Quintero <federico@nuclecu.unam.mx>
* src/io-png.c (image_save): Fixed compiler warnings. Fixed write
to unallocated memory (row_ptr), and fixed its type as well. Take
into account the ArtPixbuf's rowstride when assigning the row
pointers.
* src/gdk-pixbuf.c: Fixup includes.
* src/gdk-pixbuf-io.c: Likewise.
Ok minor changes.
No longer make a version.h, and cleaned up some code here and there, and added
a quickie dirty-hack rotation function. However, it rotates at the origin.
Is this what we want? Or do we want a rotate w.r.t. the center of the pixbuf?
Anyone.
Mark
1999-07-16 Larry Ewing <lewing@gimp.org>
* src/testpixbuf.c (expose_func): reverted the expose everything
changes, I'm not sure why these went in.
(config_func): bring this up to date with the new pixbuf_scale
semantics.
* src/gdk-pixbuf-io.c: added a couple of warnings to the module
loading code so that poeple can diagnose problems better.
* src/gdk-pixbuf.c (gdk_pixbux_scale): fix the borkedness, also it
no longer allocates a new pixbuf, which make things nicer for the
rest of the code. Unfortunately there is still a problem with
scaling rgba images.
Massive update...
gdk-pixbuf-io.c: Fixed to compile and run in a very crippled state.
io-bpm.c: Rough start on a WIN/OS2 BMP loader
testpixbuf.c: Really crude test program for gdk-pixbuf
io-gif.c: Fixed some boneheaded uninitalized variables causing the
loader to choke
