Hi
I've encountered some problems whilst using PIL and trying to produce a
gif file with transparency.

the above image is a double box 20x20 pixels in size.
I wanted to set the top right and bottom left corner to transparent.
in my code I have:
im = Image.open("doublebox.gif")
im.info['transparency']=im.getpixel((19,0))
the resulting im.info shows
'transparency': 0}
then I did
im.save("mybox.gif")
and when I displayed it in netscape, the transparency did not work.
so I opened up image again using:
im = Image.open("mybox.gif")
>> im.info
{'version': 'GIF87a', 'background': 0}
and the transparency is gone....
anyone knows how to set transparencies at all??????
need help... URGENT
