(3) The intermediate language data are generated from the next PDL data, and whether or not total data size of the intermediate language data becomes equal to or above a predetermined value is judged when YES in (2). (4) The intermediate language data are generated from the next PDL data when NO in (3). (5) Multi-level BMP data are generated from the intermediate language data and the intermediate language data are eliminated when YES in (3). (6) The multi-level BMP data are compressed. (7) The multi-level BMP data are generated from the intermediate language data when NO in (2). <P>COPYRIGHT: (C)2010,JPO&INPIT |
