The present invention provides a method and apparatus for encoding applications in an image. One embodiment of the method includes forming a first image that encodes information indicative of a map relating one or more pixel patterns to functionality implemented by a processor-based device. The first image is formed so that the processor-based device can decode the information to generate the map. The method also includes forming a second image that includes the pixel pattern(s). The second image is formed so that the processor-based device can detect the pixel pattern(s) and implement the functionality using the map.
