Open the CIPO recordAbstract From the Canadian patent
A method and apparatus for providing a faster graphical representation of lines to be displayed from their endpoint data either uses the natural symmetry of the line or imposes a forced symmetry upon the line to reduce the processing time required for generating each of the points representing the line. The order in which the endpoints are provided to the apparatus does not change the resulting representation. An interactive process starting at centers of, a partitioned line incrementally determines the positions of the pixels which best, within the concept of the invention fit, the actual line being represented.
