Hi,
maybe adding a callback to a window signal and redraw the image could be an option?

take a look at http://zetcode.com/tutorials/gtktutorial/gtkevents/

gtk_widget_add_events(GTK_WIDGET(window), GDK_CONFIGURE);

"The event mask of the widget determines, what kind of event will a particular widget receive.
Some event are preconfigured, other events have to be added to the event mask.
The gtk_widget_add_events() adds a GDK_CONFIGURE event type to the mask.
The GDK_CONFIGURE event type accounts for all size, position and stack order events."

 g_signal_connect(G_OBJECT(window), "configure-event",
     G_CALLBACK(your_callback), NULL);


Just an idea.

Ciao,
