Re: vertical text?

I understood Keith as wishing for an image with transparent background.
After creation, all pixels of a photo image are transparent, but
setting them to a color of course finishes that.

I think the transparency solution is a change to the imgrot90 code,
back to nested pixel-by-pixel loops, and setting only those which are
not in a specified background color. Pixel-by-pixel loops are slower
than setting a list of lists all in one go, but the small size of text
images may help bear the pain :^)
