In fact you don't need PyGTK you can use cairo or PIL to do the job. If however you are using PyGTK anyway or are also going to use the image within PyGTK, the basic procedure is:
- load a pixbuf with the image from a file using gtk.gdk.pixbuf_new_from_file() - create a pixmap of the same size using gtk.gdk.Pixmap() or gtk.gdk.Pixbuf.render_pixmap_and_mask() - draw the pixbuf image on the pixmap using gtk.gdk.Drawable.draw_pixbuf() (not needed if render_pixmap_and_mask was used) - draw your text, lines, etc. in the pixmap using either the cairo or gtk methods - transfer the pixmap to the pixbuf using gtk.gdk.Pixbuf.get_from_drawable() - write out the image using gtk.gdk.Pixbuf.save() John _______________________________________________ pygtk mailing list pygtk@daa.com.au http://www.daa.com.au/mailman/listinfo/pygtk Read the PyGTK FAQ: http://faq.pygtk.org/
