Does anyone have a good method for determining the area (square pixels) of a
Macintosh polygon?  The method I'm going to use would be to copy it to a
blank offscreen bitmap, then scan through the bits looking for an edge, then
count bits until I hit the next edge.

Any better ways (or a fast algorithm to do the above??)

Thanks,

Owen
