Hi Tim,

It's enough to use gtk_image_viewer_set_image() once to a pixbuf that
is handled by your application. You may then change that pixbuf() through
your own code, and then just call gtk_image_viewer_redraw() to have it 
render your changes. 

You may want to have a look at my image viewer giv for an example of a program
using the gtk_image_viewer(). The sources are also at gnome cvs, as
well as at:
