I'm confused by the behavior of the paste() method. I'm trying to
paste a PNG image onto a background generated by Image,new().
It appears to me from the manual that if flag.png is a 30x30 image,
the following sequence of operations
im = Image.new("P", (60, 60))
flag = Image.open("flag.png")
im.paste(flag, (15, 15))
ought to leave the flag pasted onto the middle of a black background.
It doesn't. All I see is black.
PIL 1.1.3, Python 2.3a0, Red Hat 8.0.
While we're att it, how do I generate a new image that is transparent?
Or set a transparency color on an existing image? Setting the
'transparency' memeber of an image's info dict doesn't seem to do it.
What am I doing wrong?
