Image processing apparatus and image processing method that perform, in units of band areas, rasterization based on second intermediate data stored in a first memory area and compressed raster data stored in a second memory area
An image processing method of performing rasterization of a page in units of band area includes, among other things, performing, in units of band areas, rasterization based on second intermediate data stored in a first memory area for storing intermediate data and compressed raster data stored in a second memory area. The rasterization of the plurality of band areas is performed in parallel. In addition, the performing of the rasterization based on the second intermediate data and the compressed raster data includes selectively decompressing, in units of predetermined areas, a piece of the compressed raster data stored in the second memory area, in accordance with which band areas, of a plurality of band areas, are to be subject to the rasterization.
