Abstract:
1. A method for rendering an image described in a page description language, the image description including at least one vector graphic object each vector object being associated with a respective color and a respective original colorant recipe for emulating the respective color, wherein the method compensates for spatial variation in a color rendering performance of an associated rendering device, the method comprising: determining the original colorant recipe of at least one selected vector graphic object of the at least one vector object; determining at least one respective intended rendering location in image rendering space of the at least one selected vector graphic object; measuring the spatial variation in the color rendering performance of the associated rendering device related to rendering the color of the at least one selected vector graphic object, thereby generating spatial variation information associated with rendering the respective at least one respective color of the at least one selected vector graphic object; determining respective location specific compensation information for the at least one respective intended rendering location from the spatial variation information and the at least one respective intended rendering location; generating at least one respective transformed colorant recipe from the at least one respective original colorant recipe and the at least one respective location specific compensation information; replacing the respective original colorant recipe of the at least one selected vector graphic object with the at least one respective transformed colorant recipe; and rendering the image including the at least one selected vector graphic object and the associated at least one respective transformed colorant recipe at the at least one respective intended rendering location using the associated rendering device.
