Estimating the term…
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.
The method of managing a large plurality of electronic fonts in a text-processing system having a computer and data storage, each said font having a plurality of symbol-representing font symbol-representing data suitable for creating visual images of the represented symbols, respectively, said represented symbols all having a plurality of typeface attributes common to all represented symbols in a font the fonts being in families of fonts;
The machine-implemented method of selecting electronic fonts for use in presenting text and graphics, storing a large plurality of electronic font objects each of which includes a plurality of graphics-representing signals for graphics presentable by a plurality of graphics presentation devices, each of said stored graphics signals being addressable by a respective symbol ID, storing a large plurality of code pages each of which has two sections, a first section storing a plurality of code points corresponding to coded representations of text and graphics within a text stream expected to be received and a second section containing a plurality of symbol IDs, one for each of said code points in said first section whereby a code point can address a stored graphic in any one of said font electronic objects via such code page;
In a document preparation system having a programmable digital computer, input means coupled to said programmable digital computer for supplying input text and graphics digital signals thereto for being converted into a visual document, output means coupled to said programmable digital computer for receiving formatted graphic and text signals therefrom for creating the visual document using said supplied input text and graphic signals as an indication of the informational content of the document, data storage means coupled to said programmable digital computer for storing programs of instructions for enabling said programmable digital computer to format the supplied text and graphic signals for visual presentation in the document, a large plurality of electronic font sets of electronic font-generating signals stored in said data storage means for enabling said output means to create graphic characters in accordance with said supplied text and graphic signals, the said graphic characters being indentifiable within any of said electronic font sets by the supplied text and graphic signals and having a shape and characteristic in accordance with said stored electronic font-generating signals of the respective electronic font sets;
