Rule 2: If a contour falls exactly on a pixel's center, that pixel is turned on. Rule 5: If a scan line between two adjacent pixel centers (either vertical or horizontal) is intersected by both an on-Transition contour and an off-Transition contour and neither of the pixels was already turned on by rules 1 and 2, turn on the pixel which is closer to the midpoint between the on-Transition contour and off-Transition contour. This is "Smart" dropout control. """
