摘要
Method of mapping source colors from a source color device having an actual source gamut that is represented by a source convex GBD (gamut boundary descriptor) and a source non-convex GBD into target colors for a target color device having an actual target gamut that is represented by a a target convex GBM and a target non-convex GBD, comprising, 1 - if the source color to map is located outside the source non-convex GBD, a pre-mapping step that maps the source color into the source non-convex GBD, 2 - if the mapped target color is located outside the target non-convex GBD, a post-mapping step that maps the target color into the target non-convex GBD. This method allows precise gamut mapping while allowing also for simple geometrical operations using convex gamuts.
