What kinds of things are you drawing on 'map'? If it's stuff like circles and lines, or other pixmaps, you know, any sort of basic vector graphics or image compositing, you probably want to replace the entire thing with a GtkDrawingArea that uses the cairo drawing API natively. > What I can't seem to figure out from the documentation is how to replace the > gtk_image_get_pixmap() function.
