Any suggestions to speed this up

Your suggestion worked with a slight tweak to the code.
def buildBitmap2(rawData, w, h):
im = Image.fromstring("L", (w, h), rawData)
im = im.convert("RGB")
file = cStringIO.StringIO()
return wxBitmapFromImage(wxImageFromStream(file) )
On my home computer, my frame rate went from 7fps to 27fps.
I had glanced at PIL earlier in the week and did not think it would
work. Your post gave me some confidence that it would, so I looked
into it a little more. PIL looks to be quite cool.
I tried getting your second suggestion with the Dibs to work, but I
can't seem to make them work with wxWindows. I can't get access to
the underlying device context handle.
I also tried playing around with Array('c') and numarray. Iterating
over these sequences was no faster than with list. At least, it did
not change the frame rate.
