Interesting. You could straighten out the angles of the rect and think of (say) the top and right edges as a single line: o---+---+---+---+---o---+---+---o Each of o's is a corner, and each of the +'s marks off a multiple of the HCF. So what you want is for the dash to be tweaked in such a way that all three o's are in the middle of some segment. Sounds fun -- good luck! --Andy _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
