Animations

<!-- ##### SECTION Short_Description ##### -->

Animations as multi-frame structures.

<!-- ##### SECTION Long_Description ##### -->
|
|
<para>
|
|
The <application>gdk-pixbuf</application> 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>

|
<!-- ##### 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.
