ABSTRACT:
A data processing apparatus for processing a batch of outline data representative of outlines of characters each consisting of at least one stroke, each outline consisting of two or more straight and/or curved segments, the apparatus including an outline data memory storing the outline data. Each segment of the character outline is represented by coordinate data sets representative of coordinate values defining the segment, and attribute flag data indicative of whether the segment is a straight line or a curved line. The outline data memory includes a first storage area storing a plurality of groups of coordinate data sets for respective different outlines (such as regular and boldface outlines) of each character which define respective different stroke widths of the character, and a second storage area storing a common groups of attribute flags which is commonly used for the plurality of groups of coordinate data sets.
