Or, on a more general note (usefull for all kinds of situations):
use the following psuedocode:
// works for a square bitmap, rectangles are left as an exercise!
for (i = 0; i < width; i+= 2) {
WinEraseLine(x + i, y, x + width - 1, y + width - 1 + i);
WinEraseLine(x, y + i, x + width - 1 + i, y + width -1);
}
