| 31 | The <application>Gdk Pixbuf</application> package is a toolkit for image

| 33 | <application>GTK+ 2</application> and <application>GTK+ 3</application> to
|

| 34 | load and manipulate images. In the past it was distributed as part of

| 35 | <application>GTK+ 2</application> but it was split off into a separate
|
|---|
| 36 | package in preparation for the change to <application>GTK+ 3</application>.
