Resolution independent user interface design
Graphical user interface material map objects are specified by a collection of attribute-value pairs, the collection of which comprises a complete description of the material map and may be used by a rendering engine to create a visual representation of the material map at any resolution. That is, material map representations in accordance with the invention are resolution independent. Another benefit of representing material maps in accordance with the invention is that they may be encrypted to prevent unauthorized inspection or use.
