<P>PROBLEM TO BE SOLVED: To solve a problem that when logical operation processing is specified in a plotting instruction in a method for realizing color processing of each pixel by using attribute information or the like in each pixel as additional information in developing the plotting instruction on a bit map, the additional information cannot be accurately prepared. <P>SOLUTION: In developing an inputted plotting instruction on a bit map, the logical operation processing specified by the plotting instruction is analyzed by a source, a pattern and a logical operation code which are objects of logical operation, additional information operation corresponding to each pixel on the bit map is prepared on the basis of the analysis results and the additional information of each pixel is prepared on the basis of the additional information operation. Consequently output image data of high quality can be prepared by applying image processing based on the additional information to the bit map. <P>COPYRIGHT: (C)2007,JPO&INPIT |
