Abstract: <P>PROBLEM TO BE SOLVED: To solve the problem that the divided processing of a curved line being described in a page description language on a straight line approximation involves extremely many segments, requires an extremely large operation cost for the acquisition of the line width in a device space for each segment, and enables no performance, and to perform a line drawing of a high speed and a high picture quality.  <P>SOLUTION: At the time of a line formation, the width of the line on the device space for an overall path is calculated. When all segments of the path are normal lines, or all segments are fine lines can be determined, the attribute of each segment is set by omitting the operation for each segment. Thus, the judgement for being the normal line or fine line attribute can quickly and accurately be performed. A thickening process is applied for each segment of the path which is constituted of a series of segments, and the outer shape of the line is formed. Then, by coloring the inside of the outer shape, a line image having a thicker size is formed.  <P>COPYRIGHT: (C)2008,JPO&INPIT
