On demand techniques for using data associated with a digital image suitable for rasterization at any resolution
View Patent ↗A mechanism that allows an image object to maintain state information that provides on-demand rasterization of its content to meet the needs of a specific application or output device is described. A modified resultant proxy image is linked with its original content such that the ability to access the original content is preserved. In this way, on-demand rasterization is available at any time based on requirements of a specific application or a specific device. More particularly, an image processing command set formed into an edit list is associated with the modified resultant proxy image that links it to its original content.

14. A method as recited in claim 13 , wherein the edit list includes instructions describing how the digital image is to be re-rasterized.
15. A method as recited in claim 1 , wherein the forwarding comprises:
wirelessly transmitting the image object and the associated state information file to the second node from the first node.
16. A method as recited in claim 15 , wherein the first node is coupled to the second node by way of a server node that directs the transmitting.
