I found a description of how to use a WCK drawing interface to draw into a PIL image. (http://effbot.org/zone/pil-draw-wck.htm) but I'm not sure how to use that class (SimpleDraw) to allow me to use existing WCK code. Should I use it as a "mix in" to overwrite base methods via inheritance? class MyClass(SimpleDraw, Widget): pass -- http://mail.python.org/mailman/listinfo/python-list
