Abstract
A circuit is provided which accepts digital position information from a graphics generator. This information serves as an input to a look-up table to determine whether the position information would cause any portion of a symbol from the graphics generator to be inside a clipping boundary, which boundary frames higher priority symbology. If this is found to be the case, the circuit excludes or clips the symbol portion that would otherwise interfere with the higher priority symbology.
