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!
