  • Patent number: 5452380
    Abstract: In a method and system for imaging a text by using a different font than that designated when formatting or by changing a character size, a row area width a character sequence width and a total blank width at imaging are calculated based on row area information for arranging rows of the text, character sequence information of words of each row, character size information for layouting and character size information for imaging, the total blank width is substantially evenly divided to calculate a word interval. A starting word is positioned at a right edge of the row area and other words are positioned with the word interval to determine the character sequence position for imaging, and the rows are outputted. Thus, the word interval is properly adjusted, no words are split and natural imaging is attained.

  • Patent number: 4975836
    Abstract: A virtual machine system has a processor operating as a base machine which includes a plurality of groups of registers, such as data registers, address registers and instruction address registers which are selected according to identification data identifying individual virtual machines. A respective group of registers is allotted to each virtual machine and to the virtual machine monitor in the system. A status register file is provided to effect selective access to a respective one of a plurality of status registers in the system in accordance with a virtual machine number. An interrupt processing portion is provided comparing the value of an interrupt mask level of the status word of a corresponding virtual machine with an externally generated interrupt level to control interrupt processing.

  • Patent number: 4931953
    Abstract: A line thickening method and system therefor, which holds skeleton line data of characters consisting of the kinds of lines relative to the types of shapes of lines comprising a character and sequence of coordinates of a plurality of points providing the end positions of the skeleton lines, the thickening process utilizes the kinds of lines of the end positions of the skeleton lines inside a character box for each character, and whenever necessary, one of a plurality of processes is selected for thickening, wherein thickening width data are previously stored for the right and left sides of the direction of each skeleton line viewing from one of the end positions of the skeleton line.

  • Patent number: 4897638
    Abstract: Skeleton pattern data and stroke thickness data are stored for each character composed of a plurality of strokes, and desired skeleton pattern data are converted into skeleton data enlarged or reduced by a scaling factor. Thickness data of the strokes after the scaling are generated based on the stroke thickness data and the scaling factor. An outline of each stroke of the character is generated based on the skeleton pattern data and the stroke thickness data to thereby generate outline pattern data of the character. When generating the outline pattern data based on the skeleton pattern data, a value different from the scaling factor for the skeleton pattern data is determined as a thickness scaling factor for the stroke of the character.

  • Patent number: 4748443
    Abstract: Method and apparatus for generating data for a skeleton pattern of a character and/or a painted character pattern are provided. A dot matrix pattern representative of a character pattern is stored in a memory and it is displayed on a display device, positions of a plurality of skeleton points for defining a skeleton line position of each of line segments on the displayed dot matrix pattern are specified on the display screen. Kinds of basic elements for the respective line segments are entered by an operator. Lines connecting the skeleton points of the respective line segments are superimposed on the dot matrix pattern as skeleton lines and they are displayed in a distinguishable form. A character outline pattern corresponding to the skeleton lines or a painted pattern thereof is generated based on the input skeleton point positions and the kinds of line segments.

  • Patent number: 4745561
    Abstract: The interactive character font pattern creation, editing and composition control device comprises transforming a printed font into a dot string data of "0", "1" on a drum scanner or the like, expanding the dot string data of font patterns loaded in a font pattern file to a storage to displaying on a display terminal. When a terminal user executes commands for noise deletion, automatic centering, translation, rotation, scaling/zooming, and creation of a revised font pattern through composing a plurality of font patterns to the font pattern given on a display screen, the device applies an operation according to the commands with an original font pattern expanded in the storage as input, loads it then in a storage for storing a current font pattern and displays the current font pattern on the display screen of the terminal.

  • Patent number: 4744050
    Abstract: Phrases in an input character string are registered in a table (phrase table), frequencies of occurrence of those phrases are counted and registered in the table, the phrases having high frequencies of occurrence are selected and macro codes therefor are determined, and those macro codes and the corresponding phrases are paired and registered in the macro table. A content of the macro table thus prepared may be displayed on a display screen. Thereafter, a user can enter a desired phrase by keying the corresponding macro code.
