oops! that's what I get for testing with a square bitmap! Thanks for the report -- I've put that demo in SVN, so I"ll fix it there. > Thanks heaps for that code though, did exactly what I > wanted.

It's because when you pan, you move the buffer bitmap. It doesn't actually draw right away, 'cause often the drawing can't keep up with the mouse movement. Yes, it does look a bit weird in this case, I hope it's OK. -Chris -- Christopher Barker, Ph.D. Oceanographer Emergency Response Division NOAA/NOS/OR&R (206) 526-6959 voice 7600 Sand Point Way NE (206) 526-6329 fax Seattle, WA 98115 (206) 526-6317 main reception [email protected] _______________________________________________ FloatCanvas mailing list [email protected] http://paulmcnett.com/cgi-bin/mailman/listinfo/floatcanvas
