DATA CONVERSION DEVICE AND METHOD, AND PROGRAM USING THE METHOD

摘要

PROBLEM TO BE SOLVED: To provide a data conversion device and method capable of converting diagram data to drawing data such as run length data capable of drawing a line image with stable line width by a prescribed output machine, and a program using this method. SOLUTION: This data conversion device 1 performs the replacement (adsorption processing) of the start point and end point of a locus vector by the intersection of the scanning line and sub-scanning line of the closest main scanning direction (step S12). The locus vector is replaced by an adsorption locus vector substituted by the intersection of the closest scanning lines. The data conversion device 1 then converts adsorption CAD data to run length data in relation to two or more scanning lines responding to the resolution of a laser plotter 4 (step S16). Accordingly, a stable exposure line width can be obtained to the line width of the CAD data can be obtained in the exposure by the laser plotter 4.
