Hi Dave

Thanks for the reply.  Let me research this a bit more.  I chose
.png because it seems more suitable for displaying a text image
i.e. black/white with anti-alias.   I think I found a bug in
ImageMagick and have pulled down the latest version.  I
still need to build and verify the problem.

What I mean by "offset by" is that when I run identify on
the file or try to look at it in gimp, ident gives me
something like "500x700+30+50" and gimp shows the image
offset in the canvas.  With jpeg's the image looks like
you would expect: identify gives "500x700+0+0" and the image
is centered in the canvas in gimp.

For jpegs -- which I guess everybody uses -- things look fine.
