An imaging system that provides a facility for converting highly functional complex graphical primitives that cannot be directly imaged by a less functional page description languages (PDL) such as PostScript or PCL into a plurality of less complex graphical primitives that can be directly imaged by a PDL. Some of these highly functional complex objects are three dimensional objects, high order curves, non regular areas, sampled three dimensional surfaces, off-centered pens, color blending and user programmable three dimensional shaders. These graphical objects are examined by a device handler, the characteristics of the object compared with the capabilities of the PDL of the device and if required the graphical object is transformed into a plurality of simpler objects that can be imaged by the PDL. Depending on the complexity of the graphical primitive, this transformation either creates a pixelmap of the image that is sent to the device at the device's resolution, or the transformation creates a plurality of graphic primitives supported by the device's PDL. Regardless, the desired complex image is printed, and the developer of an application program is able to utilize complex graphical primitives to develop an image that will be presented on a device irrespective of the limitations inherent in the device's actual PDL.
