Abstract
A font processing system includes font pattern storage for defining a font pattern and font pattern access parameter storage for storing parameters for making access to the font pattern storage. Address calculation is made on the basis of the font pattern access parameter and a pattern code supplied from outside to indicate a font pattern. The font pattern processing system includes a pattern drawing attribute indicator for indicating the attributes of pattern drawing by the font pattern data thus read out. The present invention processes predetermined font data at a high speed inside a font data processor on the basis of the pattern code and can easily accomplish diversification of font patterns.
