''SVDI+Raster'' is a Virtual Device Interface (VDI) which includes raster primitives for imaging applications. The raster functionality of SVDI+Raster provides a high degree of device-independence, while still allowing the user to customize image output for particular devices. Raster images can be mapped into arbitrary viewports, with various options available for specifying how the ''logical'' image data are to be mapped onto actual device pixels. Output primitives allow the user to pass image data as streams of individual pixels or as streams of pixel-runs for data compression. An extra benefit of the VDI+Raster is the capability to merge vector and raster graphics. The raster functions form an isolated part of the VDI which can easily be adapted to other general graphics interfaces. 9 refs.
