  • Patent number: 9965871
    Abstract: An image encoded with character information can be created by binarizing an input image followed by connected component labeling, and then repeating the binarization and connected component labeling on an inverted version of the input image. This results in identification of connected components. Related connected components are arranged in a family tree in which successive generations of the connected components alternate between two tree layer classifications. One of the tree layer classifications is selected based on whether certain connected components define characters. A label image is created which includes labels for the connected components except for the connected components in the selected tree layer classification.

Each computer system also includes source code of a design with the names of source code elements and an encoding module that generates unique identifiers for the source code elements according to a specific encoding algorithm. The encoding module identifies each source code element included in the source code. For each source code element, the encoding module generates a unique identifier by applying the encoding algorithm to the name of the element. When electronic design information is going to be transmitted to another computer system and the electronic design information includes source code elements, the encoding module encodes the information by replacing each source code element with the unique identifier generated for the element.

  • Patent number: 8917276
    Abstract: A graphics or image rendering system, such as a map image rendering system, receives image data from an image database in the form of vector data that defines various image objects, such as roads, geographical boundaries, etc., and textures defining text strings to be displayed on the image to provide, for example, labels for the image objects. The imaging rendering system renders the images such that the individual characters of the text strings are placed on the image following a multi-segmented or curved line. This rendering system enables text strings to be placed on a map image so that the text follows the center line of a curved or angled road or other image feature without knowing the specifics of the curvature of the line along which the text will be placed when creating the texture that stores the text string information.

  • Patent number: 8643652
    Abstract: A font subset is received that includes one or more glyphs of a master font which has a master ordering that establishes an order of precedence on the glyphs of the master font. When the font subset is received, one or more glyphs already exist in a consecutive sequence in an extensible data structure. In response to receiving the font subset, at least one existing glyph is repositioned in the extensible data structure and each received glyph of the received font subset is positioned in the extensible data structure. The repositioning of the at least one existing glyph and the positioning of each received glyph jointly establish a new consecutive sequential ordering on the glyphs in the extensible data structure, such that the new consecutive sequential ordering preserves on the glyphs in the extensible data structure the order of precedence established by the master ordering.

  • Patent number: 8643651
    Abstract: The present invention discloses a type-setting method for a text image file, which comprises steps of: dividing the text image file into a plurality of character-string images along a first direction according to the reading sequence; dividing each character-string image into a plurality of independent and individual character images along a second direction; type-setting and line-feeding the independent and individual character images in light of the dimension of a reading interface. Thereby, the present invention efficiently shows text images according to the reading interface and provides the reading convenience without often dragging both the horizontal and vertical scrollbars to adjust the shown texts on the screen of the reading interface.

  • Patent number: 8502824
    Abstract: A method is used to control a liquid crystal panel to display a character having a tilted or curved stroke. The liquid crystal panel includes a plurality of original physical pixels arranged in a matrix array. The method includes dividing each original physical pixel into three color dots of red, green and blue, and forming a plurality of display units. Each display unit includes three horizontally consecutive color dots, and at least one of the plurality of display units includes color dots from two of the original physical pixels. The method includes constructing a clear lattice diagram including the plurality of display units for displaying the tilted or bended stroke, and driving the liquid crystal panel to display the character based on the clear lattice diagram. As such, in the clear lattice diagram, at least two of the display units are vertically adjacent to each other and are horizontally offset by one or two color dots with respect to each other.

  • Patent number: 8494278
    Abstract: A method and computer program product for recognizing handwriting. A handwritten character is captured as an image of black pixels and white pixels. The image is partitioned into segments, each of which having a pixel ratio of a total number of black pixels in the segment to a total number of black pixels in the image. A reference character has segments corresponding to the image segments. Each reference character segment has a value range of a pixel ratio of a total number of black pixels in the segment of the reference character to a total number of black pixels in the reference character. It is ascertained that the pixel ratio of more than a predetermined number of segments in the image are within the value range of the pixel ratio of the corresponding segments of the reference character, from which, the handwritten character is recognized as the reference character.

  • Patent number: 8416244
    Abstract: A graphics or image rendering system, such as a map image rendering system, receives image data from an image database in the form of vector data that defines various image objects, such as roads, geographical boundaries, etc., and textures defining text strings to be displayed on the image to provide, for example, labels for the image objects. The imaging rendering system renders the images such that the individual characters of the text strings are placed on the image following a multi-segmented or curved line.
