Abstract:

A large plurality of electronically-stored fonts are managed and selected for use in a particular presentation (printing, display) of a document represented by electrical signals by either an explicit or implicit method. A new font by either selecting a completely defined font or by selecting predetermined characteristics of font graphics, such as italics, bold, point size, and the like which enable an implicit selection of a completely defined font. Such defined characteristics are interpreted by an automatic machine to complete font definitions for use by a document presentation device. A begin font command can specify a plurality of internal fonts with the order of specification indicating priority of selection for use in document presentation. Whether or not a specified internal font results in a defined font being activated is selectable by font definitions embedded with a received-text-data stream representing text/graphics to be presented. Such combination yields a presentation device and font independency to the unformatted input-text-data stream.
