you can actually do this:
inimage = Image.open('palette.bmp')
outimage = Image.open('convert.bmp')
outim = outimage.convert('P')
outim.palette = inimage.palette
outim.save('converted.bmp')
the only problam with this is that it doesn't do it very well. I decided
to read every pixel in the file to convert, and used my own algorithm to
convert the colors.
I'll let you know how i get on :-)
