Method and system for manipulating wide-angle images

摘要

A method and system in a data processing system having a display device for efficiently managing the display of an image. The image includes a number of segments, wherein only a portion of the segments may be simultaneously displayed within the display device at a selected resolution. The method and system of the present invention provides a substantially circular control icon having a defined periphery. One or more of the segments within the image may be associated with selected points along the defined periphery. A rotatable pointer element rotatable about a point within the substantially circular control icon is also provided. The portion of the segments displayed within the display device is selectively altered in response to a rotation of the rotatable pointer element. The display of the image also may be altered in response to movement of a slider or some other control element within the rotatable pointer element.
