Abstract:
An image processor for forming an image in a band-by-band manner, comprising:a data format conversion means for converting input image data of a first data format into image data of a second data format, said input data of the first data format including coordinate data of end points of respective vectors constituting an image and various modifying information which contains at least a line width, and the second data format holding said various modifying information, which contains said at least a line width, still independently of said coordinate data of end points and reducing data amount compared to said first data format;a storage means for storing an entirety of said image data of the second data format obtained by said data format conversion means;an intermediate code production means for producing intermediate codes of a third data format, which include coordinate data constituting contours of the respective vectors on which said various modifying information has been reflected, in the band-by-band manner based on said image data of the second data format; anda raster data production means for converting, in the band-by-band manner, said intermediate codes of the third data format into corresponding raster data of a fourth data format.
