how to do a zoom in/out with wxpython? what are the very basics for this purpose? I googled this, but could not find much, thanks!!

Answer 1

Instead of zoom, perhaps 'scaling' is what you're looking for:

Answer 2

You should look at FloatCanvas or FloatCanvas2. I know one of them has a zooming (and maybe panning) feature. You can get ideas about drawing rectangles from Whyteboard. Here's a few links:
