Abstract
A method for creating a scalable graphic image for display by a pixel-oriented display device. A pixel-based design of the desired graphic image is created and thereafter separated into constituent parts. A geometric descriptor is created for each constituent part. These geometric descriptors are then hinted to ensure that the constituent parts represented by these descriptors can be overlaid or combined to form a display of the desired graphic image for various point sizes. The hinted geometric descriptors for the graphic image are stored in a font file that can be accepted by a rasterizer. In response to a request to display a graphic image, the rasterizer reads the corresponding hinted geometric descriptors from the font file and generates character bitmaps defining the pixels to be illuminated to display the constituent parts. This allows the scaling of the displayed graphic image at different sizes based upon the particular requirements of the user.
