ABSTRACT:
The present invention provides methods and apparatus for a computer network system to provide compact and efficient representations of graphics commands on drawing/displaying lines, circles, etc. The methods and apparatus exploit the redundancies and/or relations of the information in drawing/displaying lines, circles, etc. and allow for fewer bytes and faster transmission rate (e.g., more graphics primitives per second) to a client tier (e.g., to a thin client appliance and/or a display on the desktop appliance). For example, one embodiment of the present invention uses commands that take advantage of the structure of spans created by drawing commands to send a base fill command, followed by fills whose locations and size are expressed as deltas with respect to each previous fill in the list. The deltas may comprise a difference between two commands, a difference between a command and another difference, a difference between two differences, and/or a plurality of differences. The differences and/or deltas may be determined by any number of relationships, such as additions and/or subtractions.
