Is there a way to associate transfer modes with DrawPicture the way you can with CopyBits? Specifically, I want to be able to draw a PICT of, say, a doughnut, where the doughnut is colored and the doughnut hole is white, on top of a blue rectangle, and have the doughnut hole be blue when I'm done. (The equivalent, I think, of calling CopyBits with the mode transparent + patCopy.) DrawPicture seems to ignore the current PenMode (as well it should) but when I tried to substitute my own QDProc for StdBits (on the theory that the PICT consisted of one giant CopyBits call) my QDProc never got called! I guess I could draw the PICT in its own offscreen port and then CopyBits that to the screen with the right transfer mode, but I'm dealing with 24-bit PICTs and really can't afford to take the space the extra port would need. Any suggestions?? Thanks. Eric Baumgartner * ebaum@dartmouth.edu Interactive Media Lab * - When in danger or in doubt, Dartmouth Medical School * run in circles, scream and shout.
