  • Patent number: 6151032
    Abstract: A method, computer system and computer-readable medium for generating an outline font of Asian language characters. The Asian language characters are defined by basic strokes. The basic strokes are identified by a plurality of key points and at least one width value. The computer system includes memory and a processor coupled to at least one output device. The processor retrieves a set of basic stroke defined characters and identifies a set of similar glyphs in the retrieved set of characters. Each glyph includes a set of basic strokes. The processor selects topographically representative glyphs from each identified set of similar glyphs, determines the intersecting points of the plurality of overlapping basic strokes for each selected glyph, generates outline data for each selected glyph according to the determined intersecting points and stores the generated outline data in memory. The processor also renders a character selected for display on an output device according to the stored generated outline data.

  • Patent number: 5852448
    Abstract: A method and apparatus for producing a stroked-based font defined by a stroke representation displayable on high or low-resolution output device. The stroke representation includes defining a basic stroke with key points and width values as its primary parameters and feature points and curve ratios stored in a predefined curve level tree type data structure as its secondary parameters. Curve ratios are retrieved from the curve level table according to resolution level of the output device. Also, hinting information for certain key points provides for a better displayed stroke in low resolution space. Hinting information is activated according to predefined data associated with the curve level table. A CAD tool allows a font designer to easily select the parameters for the design of basic strokes and stroke shapes. The CAD tool presents a real-time display of sample characters at various bitmap sizes during font creation.

  • Patent number: 4990903
    Abstract: A method and apparatus for high resolution character generation using a character generating apparatus having a first central processing unit with memory and input and output devices for processing and outputting character information, and a second central processing unit with different memory units and circuit arrangement electrically coupled with the first central processing unit for receiving character information and outputting processed character data information to produce resultant characters in various forms. The method includes the steps of preparing a character pattern description information for Chinese characters for being input into the character generating apparatus, and constructing a stroke table, a radical table and a specific symbol table for Chinese characters and other language letters for being stored in different memory units of the second central processing unit.
