Image-processing device

Abstract

The present invention provides for an image-processing device capable of printing oblique lines with an angle of approximately 45 degrees and constant width at any time to obtain a printed image of superior quality. The line-work path information whose coordinate position has been specified by a path processing section 3 is passed to a path control section 4, which stores and controls the path information. When there is an oblique line in the path information to be printed, a 45-degree line determining section 5 judges whether or not the oblique line has an angle within a given range of approximately 45 degrees relative to a horizontal axis or a vertical axis, and once determined as such, the determining section 5 passes the path information to a 45-degree line approximating section 6. The 45-degree line approximating section 6 secures and fixes all the path information of oblique lines received to a 45-degree oblique line and thereafter passes it to a line-drawing processing section 7. In this manner, all oblique lines determined to have angles within the prescribed range of approximately 45 degrees relative to the horizontal axis or the vertical axis are drawn as 45-degree oblique lines.
