Linda,

Your answer is simpler than mine for the rectangular question. But Leitzel
then came back with the same problem on a round image. Is there an easier way
to handle that case than what I came up with?

I spotted a Photoshop tutorial that included using the single-pixel
selection...but that's still on a horizontal or vertical line. *dreams*
Wouldnt' it be cool to be able to make a single-pixel selection (or one of
arbitrary width, I guess) along a vector path?

Thanks!

Lorraine
