Abstract
A method for determining crossing points of two overlapping figure outlines, where the figure is represented by a closed outline description format that includes a data array of points on the outline, includes the following steps: (1) prepare a memory space for storing a background value corresponding to the point data array and a foreground value corresponding to the point data inside the outline; (2) read the stored values in the memory space along the point data on the outline of the figure; (3) from P1 to P2, if the corresponding values stored in memory change from the foreground value to the background value then let point P2 be an out-crossing point; (4) from P1 to P2, if the corresponding values stored in memory change from the background value to the foreground value then let point P2 be an in-crossing point.
