2000-10-06 Havoc Pennington <hp@redhat.com> * Makefile.am (SRC_SUBDIRS): contrib subdir * gdk/gdkpixbuf.h: Move GdkPixbufAlphaMode to gdk-pixbuf library, so it can be used in Xlib version * demos/testpixbuf.c (update_timeout): error checking from 1.0 tree * gtk/gdk-pixbuf-loader.c (gdk_pixbuf_loader_get_pixbuf): Sync change from 1.0 tree that returns first frame of animation if the loaded file is an animation. * contrib: add new directory to hold stuff that comes with GTK+ but isn't really part of GTK+ (for now, gdk-pixbuf-xlib) * configure.in: add contrib/* 2000-10-06 Havoc Pennington <hp@redhat.com> * gdk-pixbuf.h: add GdkPixbufAlphaMode 2000-10-06 Havoc Pennington <hp@redhat.com> This entry is a summary of the merged-in changes from 1.0. Relevant original ChangeLog entries are spliced in after this entry; the files they refer to are from the 1.0 gdk-pixbuf sources. * pixops/pixops.c (pixops_composite_nearest): sync a small fix from 1.0 * io-xpm.c (xpm_seek_string): add fscanf error check from 1.0 Add progressive loader from 1.0 * io-tiff.c (gdk_pixbuf__tiff_image_begin_load): mem leak fixes from 1.0 tree * io-pnm.c: new version from 1.0 tree * io-jpeg.c (gdk_pixbuf__jpeg_image_load): sync from 1.0, use malloc not g_malloc * io-gif.c (lzw_read_byte): sync from 1.0, change a g_error to g_warning (gif_get_next_step): return 0 here, sync from 1.0 * gdk-pixbuf-util.c: sync email address change for Cody Russell 2000-09-11 Jeffrey Stedfast <fejj@helixcode.com> * gdk-pixbuf/io-pnm.c: Pretty much totally rewrote again because last nights code was still "broken". Should now properly handle all error conditions gracefully. 2000-09-10 Jeffrey Stedfast <fejj@helixcode.com> * gdk-pixbuf/io-pnm.c: Rewrote. 2000-09-09 Federico Mena Quintero <federico@helixcode.com> * gdk-pixbuf/pixops/pixops.c (pixops_composite_nearest): Compute the correct dest offset. 2000-08-25 Federico Mena Quintero <federico@helixcode.com> * gdk-pixbuf/io-xpm.c: #include <unistd.h> 2000-08-05 Larry Ewing <lewing@helixcode.com> * gdk-pixbuf/io-tiff.c: stop leaking context->tempname. * gdk-pixbuf/io-xpm.c: same as above. 2000-07-26 Michael Meeks <michael@helixcode.com> * gdk-pixbuf/io-jpeg.c (gdk_pixbuf__jpeg_image_load): make g_malloc a malloc. 2000-07-21 Larry Ewing <lewing@helixcode.com> * gdk-pixbuf/io-xpm.c: add a fake progressive loader so that xpm at least supports the progressive interface like the one in io-tiff.c. This should be reimplemented as an actual progressive loader. 2000-07-19 Jonathan Blandford <jrb@redhat.com> * demo/pixbuf-demo.c (update_timeout): changed scaling level to make it look better. * gdk-pixbuf/testpixbuf.c (update_timeout): Patch from michael meeks to handle errors better.

Animations as multi-frame structures.

<para>
|
|
The &gdk-pixbuf; library provides a simple mechanism to load and
|
|
represent animations, primarily animated GIF files. Animations
|
|
are represented as lists of #GdkPixbufFrame structures. Each
|
|
frame structure contains a #GdkPixbuf structure and information
|
|
about the frame's overlay mode and duration.
|

|
<!-- ##### ENUM GdkPixbufFrameAction ##### -->
|
|
<para>
|
|
Each animation frame can have several things happen to it when the
|
|
next frame is displayed. The #GdkPixbufFrameAction determines
|
|
this. These are essentially the overlay modes supported by GIF
|
|
animations.
|
|
</para>
|
|
|
|
@GDK_PIXBUF_FRAME_RETAIN: The previous image should remain displayed,
|
|
and will potentially be occluded by the new frame.
|
|
@GDK_PIXBUF_FRAME_DISPOSE: The animation will be reverted to the state
|
|
before the frame was shown.
|
|
@GDK_PIXBUF_FRAME_REVERT: The animation will be reverted to the first
|
|
frame.

<!-- ##### STRUCT GdkPixbufFrame ##### -->
|
|
<para>
|
|
This structure describes a frame in a #GdkPixbufAnimation. Each
|
|
frame consists of a #GdkPixbuf, an offset of the frame within the
|
|
animation's bounding box, a duration, and an overlay mode or
|
|
action.
