  • Patent number: 6266070
    Abstract: A character pattern generator includes: an input section for inputting an input information that contains a character code, a character style, and a character size of a character pattern to be generated; a character information storing section for storing, for each character code, a character information containing a stroke configuration information composed of skeleton coordinate data of strokes constituting the character pattern; a bit map font generating section for reading, from the character information storing section, the stroke configuration information contained in the character information based on the input information input by the input section and for generating a bit map font based on the skeleton coordinate data of the stroke configuration information that has been read; and an output section for outputting, as a character pattern, the bit map font generated by the bit map font generating section.

  • Patent number: 6011561
    Abstract: A character generator is formed by a microcomputer and has a structure in which character structure information including radical structure information representing a kind and a position/size of a radical of kanji or like characters and each stroke information other than the radical is stored for each character code and for each typeface in a ROM. Each stroke information of the radical based on the radical structure information is stored for each typeface in the ROM. and contour information corresponding to the stroke information is stored for each typeface in the ROM. A CPU sequentially reads and positions the stroke information such as the radical corresponding to the typeface, and assigns the contour information to generate a character pattern. Consequently, a data capacity can be reduced to generate, according to the kind of the typeface, a character pattern of high quality which takes a stroke shape of the radical and a balance thereof into consideration.

  • Patent number: 5870107
    Abstract: A character and symbol pattern generator includes a skeleton data storage device for storing beforehand, for every skeleton pattern. Skeleton data includes coordinate data of each skeleton point at which changes occur at least in the stroke direction of skeleton pattern for forming characters and symbols, two thickness data which represent lengths of two thickness segments of a stroke on the start and end points of the skeleton pattern, and two angle data which represent angles of the two thickness segments with respect to the stroke direction or the horizontal direction. An input device is used to designate the kind and size of the character and symbol. A thickness data calculating device calculates thickness data of each skeleton point from the two thickness data of the start and end points and the coordinate data of each skeleton point.

  • Patent number: 5867172
    Abstract: A character generating device which is capable of creating a clear thickened or thinned (wider or narrower) character by eliminating an improper portion of an outline of a character. According to a character code input from an input portion, a CPU obtains outline font data for one character from a font data storage and transfers the data into a RAM. On the basis of the character code input from the input portion, the CPU searches a head address of a memory storing data for a required character and transfers the data from the address into the RAM. A character thickness processing portion performs character thickening or thinning operations on each point sequence composing each outline of the outline-font character and a point-sequence transferring portion determines, by use of functions or a table, a correct destination and transfers thereto the improper point-sequence on the thick or thin processed outline of the outline-font character.

  • Patent number: 5850228
    Abstract: A character pattern generating apparatus includes a memory and a CPU. The memory stores, in advance, character skeleton data representing the skeleton shapes of characters and element outline data representing the outline shapes of the elements constituting the characters for each character style. The CPU obtains outline shape data corresponding to one constituent element in character skeleton data from the element outline data, extracts therefrom element skeleton data for the constituent element, transforms the extracted element skeleton data based on the character skeleton data, and modifies the outline shape data in accordance with the transformation so as to generate a character pattern by using the modified outline data. The character pattern generating apparatus of the present invention generates multiple kinds of high quality fonts involving no design restrictions in a smaller number of steps.

  • Patent number: 5771035
    Abstract: A character generation device that easily implements a multiple-font system without increasing the data amount is provided. Character data of a basic font is stored in a character data storage while paste component data is stored in a paste component data storage. A shape recognizer determines a length and an angle of a process-target element as well as an angle of a stroke to which the process-target element belongs, by referring to a font attribute storage based on a font code and character number specified from a keyboard. A paste component data modifier performs scaling up/down processing and rotation processing with the selected paste component data by referring to the font attribute storage. A data synthesizer generates character data that paste components, subjected to the scaling up/down process and the rotation process, are applied onto the process-target element.

  • Patent number: 5633991
    Abstract: A method and device for generating a character line of uniform width throughout character size conversion includes predetermining an offset value corresponding to a target line width; adjusting a line width of each character part to the target value without consideration of respective line widths; obtaining coordinate data by reading coordinates of a dot sequence of each character part; reading an offset value corresponding to a character size after coordinate transformation on the basis of the read-out coordinate data. A reference point for a character part from the coordinate data is selected and coordinates of the dot sequence of the character part are transformed to a specified size. A character part font is generated using the transformed dot sequence and superimposing a character part font onto another character part for plotting a character.
