<!-- ##### SECTION Title ##### -->
Animations
<!-- ##### SECTION Short_Description ##### -->
Animations as multi-frame structures.
<!-- ##### SECTION Long_Description ##### -->
<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.
</para>
<!-- ##### SECTION See_Also ##### -->
<para>
#GdkPixbufLoader
</para>
<!-- ##### 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.
</para>
