Abstract:
1. An image processing apparatus which sends attribute information to a selection unit configured to determine based on the attribute information whether to print with only a black coloring material or to print with a plurality of coloring materials, the image processing apparatus comprising: a determination unit configured to make a determination to perform processing for changing the attribute information of compressed data, whose rendering color is monochrome and which is compressed by a compression format for compressing a monochromatic image, from an attribute which is printed with a plurality of coloring materials to an attribute which is printed with only a black coloring material; a change unit configured to perform the processing for changing the attribute information of the compressed data based on the determination made by the determination unit before the attribute information is sent to the selection unit; a region determination unit configured to determine what kind of region a pre-compression region of the compressed data was, wherein the determination unit is configured to make a determination to perform the processing for changing the compressed data when it is determined by the region determination unit that in the pre-compression region the attribute information is generated as an attribute which is printed by only a black coloring material, and wherein the determination unit is configured to make a determination not to perform the processing for changing the attribute information of the compressed data when it is determined by the region determination unit that in the pre-compression region the attribute information is generated as an attribute which is printed by a plurality of coloring materials, wherein the region determination unit is configured to determine whether the compressed data is overlaying another compressed data, and when it is determined that the compressed data is overlaying another compressed data, determine that in the pre-compression region the attribute information is generated as an attribute which is printed by the plurality of coloring materials, and when it is determined that the compressed data is not overlaying another compressed data, determine that in the pre-compression region the attribute information is generated as an attribute which is printed by only a black coloring material.
