Abstract:
1. An image processing apparatus comprising: intermediate data generation means for generating intermediate data in which information relating to a gamut mapping algorithm is added for each object described by a description language including at least an α blending; rendering means for performing a rendering of the intermediate data into bitmap data for each object and for adding the information relating to the gamut mapping algorithm to each pixel of the bitmap data; and color space compression means for performing, according to the information relating to the gamut mapping algorithm added to each pixel, color space compression from each pixel of the bitmap data into color space data of a printer, wherein the α blending is performed between an object of a first color space and an object of a second color space different from the first color space, and wherein the color space compression of the α blended object is performed according to information relating to a gamut mapping algorithm for the α blending.
