Bitmaps - PCB registration

Well, I can produce a registration target in BMP for you, but I'll have to
spend the same 10 minutes that you'd hve to spend. Normally, the things
look like a circle with a centered crosshair over it. What's also
frequently seen is a mounting hole sized to accomodate a dowel pin to keep
the panels aligned for routing. That's just a mounting hole drilled in the
center of strategically placed alignment targets.

If I send you a BMP image of a target, can you size it with your software,
or do you need several sizes?
