PROBLEM TO BE SOLVED: To provide a plotting information processing device capable of reducing the amount of data in the conversion of a plotting command containing ROP processing into intermediate data and outputting at high speed. SOLUTION: A command is produced and stored in a print command storage part 15. When a plotting command analyzing part 13 judges that an inputted plotting command is a command requiring the ROP processing, a print command extracting part 17 extracts a print command in a destination region from the print command storage part 15, and converts it into raster data in a resterizing part 18. An ROP processing part 19 conducts ROP processing according to the processing command requiring the ROP processing. A color information judging part judges whether a result is monochromatic or not, and if monochromatic expression is possible, the raster data of an ROP processing result is annulled, and the color information of the plotting command requiring the ROP processing is altered. Thereby, increase of the amount of data caused by the ROP processing is suppressed and the high speed processing is made possible. |
