Abstract:
1. A method for performing color management of color image data using a device transform, the method comprising the steps of: generating an identifier key based on contents of a color measurement profile for a color device, the color measurement profile containing measurement data corresponding to the color device; determining if a device transform corresponding to the identifier key is present in a device transform cache disposed in a persistent memory; loading, in the case that it is determined that a device transform corresponding to the identifier key is present in the device transform cache, the device transform into a program-accessible transient memory; generating, in the case that it is determined that a device transform corresponding to the identifier key is not present in the device transform cache, a device transform based on the measurement data in the color measurement profile, and storing the generated device transform in the device transform cache in correspondence with the identifier key; and transforming the color image data based on the device transform loaded in the program-accessible transient memory.
