[comp.sys.mac.programmer] Memory Map of Screen -- HELP

rudd@bgsuvax.UUCP (Michael Rudd) (06/17/88)

	I'm looking for some information on how the Macintosh 
	does it's screen mapping.

	I am writing programs using Borland's Turbo Pascal and am trying
	to simply light one pixel on the screen.

	Currently the only way I seem to be able to do this is by saying
	
		MoveTo(x,y);
		LineTo(x,y);

	because there isn't a toolbox routine that I can find to light
	one pixel. This becomes slow if many pixels are going to be
	lit.  What I would like to know is if there is some way I can
	access the screen map and turn a pixel on myself without using
	a toolbox routine.

	Any suggestions would be greatly appreciated.
