34 | The <application>Gdk Pixbuf</application> package is a toolkit for image

35 | loading and pixel buffer manipulation. It is used by
|
---|
36 | <application>GTK+ 2</application> and <application>GTK+ 3</application> to
|
---|
37 | load and manipulate images. In the past it was distributed as part of
|

38 | <application>GTK+ 2</application> but it was split off into a separate
|
---|
39 | package in preparation for the change to <application>GTK+ 3</application>.
