Hello, 1. The Think C profiler indicates Line(1,1) is nearly twice as fast as Line(0,0) or Line(1,0) or (0,1). I am curious as to why, but what is the fastest way to draw a single pixel, ie. Point(x,y)? 2. After doing alot of drawing, I wish to put part of the screen on the clipboard. Is it true that I can turn a pixel map into a PICT format by CopyBits inside OpenPicture() and ClosePicture(). Since I have successfully implemented an offscreen GrafPort with its own PixMap for window updating, I can CopyBits to it -- simple, but all I get is an empty rectangle. The size of the Picture after the CopyBits is also too small to hold the PixMap. Any suggestions? Thanks in advance. ------------------- Brian Rasnow Caltech 216-76, Pasadena CA 91125 (818) 356-6818 rasnow@bek-mc.cns.caltech.edu rasnow@caltech.bitnet Peacenet: rasnow -------------------
