Abstract:
1. A page description data processing apparatus comprising: an object confirming computing unit which confirms whether or not page description data contains an object for stroking a path; an operator confirming computing unit which, if the page description data contains the object for stroking the path, confirms whether or not a dotted line pattern determining operator for determining a dotted line pattern that is formed along the path within the object and has a periodic repetition of line elements and gaps is contained within the object; a line element start point position estimator computing unit which, if the dotted line pattern determining operator for determining the dotted line pattern is contained within the object, estimates the position of a start point of each of the line elements formed along the path based on a path construction operator for constructing the path and the dotted line pattern determining operator; and a path end point position changer computing unit which, if the distance between an end point of the path and the start point of one of the line elements closest to the end point of the path is equal to or less than a prescribed threshold value, changes the position of the end point of the path to another position along the path in order to increase the distance, while maintaining a phase of the periodic repetition at a start point of the path, wherein the path end point position changer computing unit determines the prescribed threshold value depending on a resolution utilized during rasterization of the page description data.
