Patent ID: 7800636

Claim:
A system for causing a portion of graphical material to be magnified and displayed, the system comprising: a memory storage; and a processing unit coupled to the memory storage, the processing unit being operative to: determine scaling parameters comprising source identification, scale, target identification, and display type, wherein the source identification, the scale, the target identification, and the display type comprise elements in determining a magnification and display of the portion of the graphical material corresponding to a magnification source specified by the source identification parameter; receive an indication that the magnification source has changed in one of content and position; and transmit the scaling parameters to an external graphics engine, wherein the external graphics engine is operative to generate and cause to be displayed a scaled output corresponding to the changed portion scaled in accordance with the transmitted scaling parameters, wherein the external graphics engine comprises: a component scaler for scaling the selected portion of the output display to create the scaled portion in accordance with the transmitted scaling parameters, and an image compositor for combining the output display and the scaled portion in a specified target area of the output display identified by the target identification parameter.
