    Abstract: The method for line patterning may include receiving line data for a first line. The line data for the first line may include an original starting point and an original endpoint. The first line may be divided into one or more line segments, which may include generating a new starting point and a new endpoint for one or more of the one or more line segments. The new line segments may then be rasterized from the new endpoint to the new starting point. In other words, each line segment may be rasterized from right to left, thus avoiding problems associated with multiple consecutive accesses of pixel addresses in the pixel buffer. The original or intended line pattern of the line is preserved since the zeros and ones are drawn or rendered in their appropriate locations as if they were being drawn left to right, even though they are actually rasterized from right to left.
