this is what LiveCode does not like: ... from rect a,b,c,d... Try this: ... put a & "," & b & "," & c & "," & d into tRect export snapshot from rect tRect of img "LargeBitmap" of cd "BitMapStore" of stack "FullSizeBitMap" to img "TestImage" of cd 1 of stack "Test" ... > TIA > > Graham > > PS If anyone knows any other way of non-destructively copying a part of an > image without munging the clipboard, I'd be more than happy to use it. That's what I would like to know, too, as long as fiddling with "imagedata" is not involved ;-) Best Klaus -- Klaus Major http://www.major-k.de kl...@major.on-rev.com _______________________________________________ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
