Abstract
The invention method and apparatus employs font metrics data related to font bitmaps for characters of a desired font. Position offsets of pieces in composite characters are read from the font metrics data and are converted to the appropriate pixel offset to adjust the bitmaps of subject compressed font characters. The adjusted bitmaps of the different pieces of a subject composite character are combined to form a working bitmap which represents each piece of the composite character in full size in the subject font. Screen display of composite characters decompressed to full-size is supported by the formed working bitmaps.
