Abstract: A method and system for encoding an operation in a graphics image. The method and system encode the operation as a graphically encoded object that is drawn as part of the graphics image. When rendering the graphics image, the method and system locate the graphically encoded object and perform the operation corresponding to the graphically encoded object. In a preferred embodiment, the graphically encoded object is a polygon of an uncommon color. In the preferred embodiment, the operation performed is to replace the graphically encoded object with a replacement object of the same size and shape as the graphically encoded object. In the preferred embodiment, the graphics image is represented by a metafile that includes plural metafile records. The preferred embodiment enumerates each metafile record to determine whether the record corresponds to the graphically encoded object. If so, then the operation corresponding to the metafile record is performed.
