A method is disclosed. The method includes intersecting a clip polygon with a source image, determining destination coordinates of the clip polygon, rasterizing the clip polygon, determining a bounding box, dividing the bounding box into a plurality of logical destination tiles, processing the destination tiles to determine coordinates of source tiles corresponding to each of the destination tiles and performing rotation processing of the source tiles, wherein each tile is processed independently.

An image processing apparatus which performs image processing for print processing, including: a pseudo halftone processing unit configured to perform pseudo halftone processing by dithering with respect to an input image, and generate a halftone image constituted by plural dots, and a threshold matrix holding unit configured to hold a threshold matrix used for the pseudo halftone processing, wherein in the threshold matrix, thresholds are arranged such that the halftone image has a density region in which dots to be formed depending on a density of the input image are not rotational symmetric on a 90 basis, and orientations of the dots differ from each other in the density region.

An object of the invention is to solve low productivity of foil-stamping printing due to frequent replacement of foil rolls when the positions of sizes of foil objects are different in a plurality of jobs. A grouping unit groups jobs on the basis of a foil roll which can be attached to a foil stamping device and foil object information. A job sorting unit sorts the grouped jobs on the basis of a sorting policy by group. A foil-stamping print data transmitting unit transmits foil-stamping print data including the foil object, which is extracted from print data to a foil stamping device. A foil roll replacement information output unit outputs foil roll replacement information indicating a timing that a foil roll is replaced.
