Abstract
An image processing device which is designed to trace a pixel line in a pixel line data and provide a polygonal line data. The image processing device is provided with a pixel line tracing means for forming a tracing dot data by tracing one pixel after another in the pixel line, a tracing direction selecting means for selecting a direction substantially coinciding in a branch direction with the pixel line tracing direction on the basis of the tracing dot data obtained so far by judging the branch direction nearby a pixel at the branch point when the pixel line tracing means detects the pixel at the branch point by tracing, and a polygonal line processing unit for forming a polygonal line data by selecting a pixel line tracing direction by the tracing direction means, causing the pixel line tracing means to continue the tracing of the pixel line in substantially the same direction over the branch point, and forming a tracing dot line. The image processing device permits an effective processing of polygonal lines in the image processing.
