摘要:
Disclosed is an image forming system (1) provided with: a controller (2) which comprises a list creation means (21) for creating a display list, a decompression means (23) for decompressing image data that has been compressed, a drawing means (22) for performing drawing from image data, and a print data creation means (25) for creating print data; and a rasterization accelerator (3) which comprises a second drawing means (31) for performing drawing in accordance with the display list, and compression means (32, 33, 34) for compressing image data drawn by the second drawing means, wherein the rasterization accelerator is provided with a determination means (35) for determining from display list information whether or not image data is compressed and for determining the compression method employed when compression is performed by the compression means, the determination means (35) being provided for the purpose of allowing optimal compression in accordance with the type and volume of image data and for the purpose of compressing image data to the greatest extent possible in order to reduce transmission time to a controller.
摘要:
Disclosed is an image-forming apparatus (1) equipped with a conversion means (21) for converting a page code language into a render command; a first rendering means (31) for rendering the render command using a hardware processing means (3); a second rendering means (22) for rendering the render command using a software processing means (2); a storage means (33) for storing information related to the render command that renders using the first rendering means; a reading means (26) for reading information related to the stored render command; judgment means (27) for judging whether to render the render command using either rendering means based on information related to the read render command; and a control means (28) for rendering the render command with the judged rendering mean. Objects are to suppress expansion of a hardware circuit size and to increase flexibility without requiring a change of software to correspond to a change of hardware.
