Drawing a grid on a picture

[Jive Dadson]

Hello folks. I know precisely zero about image processing. I want to
draw a grid of lines one or two pixels wide on a picture (.jpg, .png, or
whatever). [I want to transfer a sketch of the picture to a canvas (for
oil painting), using the "grid method."]

I figure this is probably a very easy thing to do, but I can't seem to
find the documentation I need. It all seems to assume you already know
something. I have wxPython installed. I also have the wxPython demo.
The section "Using Images/Image" looked promising. It just shows how to
read a picture and display it as a bitmap.

Can someone show me how, or point me in the right direction?

Thanks a lot.

I also found a reference to something called PIL. Maybe that's the
ticket. If so, where can I find it (with documentation)? Thanks.

The will likely do what you want. And you can find it the same way that
you would find anything online i.e. with google. But here is the link:

Just google for PIL and Python.

Thanks Brian and Sybren. PIL did the trick. Real easy.
