Patent abstract
A method of converting between color spaces where color components are cached when they are well-defined after color space conversion. When the components become undefined after conversion, the cached values are used instead of using an arbitrary default value. The resulting color editing system is “robust” in that it matches users' expectations, shielding them from surprising glitches introduced by the user of the arbitrary values for undefined color components.
