Hi Sarah and Ben,
ok, I wasn't very clear:
- I want to PAINT, not DRAW by script; using graphics is not possible
because there would be too many objects, making scrolling and dragging
too slow, so I want to create a "background" picture instead. I don't
find out how use the paint tools in a script.
- at times I want to repaint portions of the picture (because I don't
have graphic objects); it would be easy if I had soemthing like a
cliptrect which helps me limit the painting to just that portion.
The second is not so essential because I can replace cliptrect with a
bit of thinking. But the painting thing is a pure mystery to me, still.
