PIL can be used with any number of the various GUI toolkits available
for Python. Here's some info about using it with wxPython:

What is it you want to do with them? wxPython can load and display PNGs
with alpha, but there is no way to create them with wxPython, and I
don't know if you can put them on top of each other

You might want to also take a look at wxArt2d. Sadly, however, it not
yet been wrapped for use with Python.

Well, I think you get at least two copies of the data: one to make the
string, and then another one to make the wx.image. It would be nice to
just pass a pointer to the data buffer right through to wx.Image.

why not pass the data to numpy, then convert -- that will be a lot easier.

The latest version of PIL supports this directly, you can do:

I still don't think so: explanation below.
By the way, there is another problem with your example -- I get an

I do agree that it's not ideal like this, but not bad, once you expect it.

HI folks,
I'm creating, then drawing to, a "P" paletted image.
I like how ImageDraw will let you set the colors as you drawm and it
will automaticaly get added to teh palette.
However, I can't see how to initialize the image with a given
background (fill) color:

not really -- this list os for more general image processing tools

There must be an OpenCV list somewhere.
If not, I'd try the scipy list, I expect there are users on there
