<p>PROBLEM TO BE SOLVED: To make a shape of a diagram after being rasterized similar to a shape of a diagram indicated by original data.SOLUTION: A vector data processor 12 comprises: an attenuation part 301; a core line acquisition part 302; and an overlapping part 303. Object diagrams which are processing objects include a linear diagram having width. The attenuation part 301 performs processing to object vector data 231 for acquiring attenuated data 232 obtained by attenuating the object diagram indicated by the object vector data 231. The core line acquisition part 302 performs processing to the object vector data 231, for acquiring core line data 233 indicating a core line of the object diagram. The overlapping part 303 creates data which instructs recording of a synthetic diagram obtained by overlapping the attenuated diagram and the core line. By overlapping the attenuated diagram and the core line, line break due to attenuation can be prevented and the object diagram can be attenuated. As the result, a shape of diagram after being rasterized is made similar to a shape of diagram indicated by original data.</p> |
