Abstract
A computerized system inputs fonted text and outputs corresponding fonted text containing new, automatically created, font descriptions. The new font descriptions make the output a portable document which can be rendered at any magnification by a machine of any output resolution, even if that machine does do not have access to the pre-defined font descriptions associated with the original input text. The system creates the portable document by accessing the pre-defined font descriptions of each character-font shape in the input text and generating new font descriptions which describe those shapes in a new font description language. Preferably the system findspoints on the outlines of each character-font shape which are a function of the shape itself, rather than how its pre-defined description describes that shape. The system bases the segmentation of the new font description on such description-independent points. Once created, the portable document can be rendered on the computer or printer generating it or a computer or printer receiving the document over a network or on mass storage media. In some embodiments, the computer viewing the portable document determines whether can ac…
