Abstract
A method of rendering at least part of an image from an at least one external source into a two-dimensional memory array having integer x and y pixel coordinates based upon a set of integer coordinates of an outline of the rendered image. The method includes the steps of forming a parallelogram defined by a parallel series of effect lines forming an angle e with either the x or y axis of the memory array and bounded on opposing ends of the scan lines by a scan axis, the parallelogram surrounding at least part of the two-dimensional memory array and rendering the image from the at least one external source into the memory array while moving unidirectionally along the effect lines and scan axis using the outline coordinates as transition points for selection and non-selection of the image.
