Method and apparatus for highlighting graphical objects
First Claim
1. A method for highlighting a selected object on a display, the method comprising:
- rasterizing base graphic data to provide a base graphic raster, the base graphic raster comprising at least one graphic object including a selected graphic object to be highlighted;
providing selection graphic data including a graphic object corresponding to the selected graphic object;
rasterizing the selection graphic data to yield a selection graphic raster; and
, compositing the base graphic raster and the selection graphic raster to yield an output graphic raster for display.

Abstract
Methods and apparatus are provided for highlighting one or more selected objects in a raster image. A rasterizer renders base graphics data containing a plurality of graphic objects to produce a base graphic raster. When a user selects object(s), selection graphic data is generated. The selection graphic data includes a selected graphic object corresponding to the object(s) to be highlighted in the base graphic data. The rasterizer renders the selection graphics data to yield a selection graphic raster. The selection graphic raster and the base graphic raster are composited to yield a graphic raster for display wherein the selected object(s) are highlighted.
