  • Patent number: 10762401
    Abstract: A method for generating bitmap image data of a page includes acquiring print data of a page including compressed images, and performing rendering of bands included in the page based on the print data to generate the bitmap image data. The performing of the rendering performs rendering at least two of the bands concurrently. The performing of the rendering includes decompressing the compressed images, and using the decompressed images for corresponding bands of the bands to generate the bitmap image data. The decompressing decompresses, into a same memory area in a decompression buffer, at least two compressed images used for different bands, so that one of the two compressed images is decompressed into the same memory area and another of the two compressed images is decompressed, after rendering of a last band for which the one of the two compressed images is lastly used is finished, into the same memory area.

  • Patent number: 9824305
    Abstract: An image processing apparatus performing a rasterization process with a scanline method interprets a received printing job and generates objects. In an objecting combining process, the reception objects are spooled, the generated objects are interpreted, and it is subsequently determined whether or not the objects are vertically long objects to be combined into a single object. If the objects are determined to be the vertically long objects, an object combining process is performed to render the vertically long objects respectively in a longitudinal direction to form the single object.
