[comp.sys.amiga.tech] overscan drawing.

dak%ritcv@cs.rit.edu (340 Ok) (02/06/90)

hello,

	I have written a program that converts RGB8 files from Turbo
Silver to HAM images.  The problem is that when the image is overscan,
I need to be able to write the pixels to the left and above the normal
viewing area.  I open a screen at the overscan resolution and then a
window on that screen.  Using WritePixel(rp, x, y) to draw on the screen,
the coords (0,0) put a dot in the upper left corner of the normal
viewing area.  I wish to put a dot in the extreme upper left of the screen
in the overscan area.  HOW CAN I DO THIS?  (I have an A1000/LUCAS w/2meg
Starboard2 and Lattice 5.0)
 
			Thanks!
