Abstract:
A method of labeling image object data in a digital imaging device on a per-pixel basis by a print engine of the imaging device, the method comprising the steps ofreceiving first page description language data into the digital imaging device; executing the first page description language data in the digital imaging device to set a first transfer function procedure of a transform matrix to thereafter generate a first predetermined tag value in pixels of image objects when the image objects are rendered to a frame buffer by the transform matrix; receiving, into the imaging device, first image object data to be rendered to the frame buffer, the first image object data being of a first image object type; executing a first paint operator associated with the first image object data; and, rendering the first image object data using the transform matrix to generate a first set of pixel display values in the frame buffer of the imaging device representative of said first image object data, each of the first set of pixel display values containing at least one first identifier bit corresponding to said first predetermined tag value to relate the first image object data to the first image object type.
