  • Patent number: 9373049
    Abstract: Techniques for determining whether touch-input gestures approximate straight lines and for animating a display with such gestures are described. Some techniques receive a gesture input through a display, define an oriented bounding box for the gesture, and determine whether the gesture approximates a straight line based on an amount of the gesture that is contained within the oriented bounding box. Other techniques determine a linear regression line for pixel locations comprising a gesture, determine distances of the pixel locations from the linear regression line, and render the set of pixel locations to the display based on the distances and a threshold. Further techniques record a gesture input through a display, determine a sequence of frame updates for the gesture, each frame update including a part of the gesture, and provide the frame updates for sequential updating of the display to effect an animation of the gesture on the display.

  • Patent number: 8495491
    Abstract: A method, system and apparatus for locale and operating platform independent font selection. In an operating platform having an operating platform configuration and an associated locale, a locale and operating platform independent font selection method can include parsing a pre-established font properties file to identify whether a desired font referenced in the font properties file supports at least one of the operating platform configuration and the associated locale. Consequently, if it is indicated within the font properties file that the desired font supports either or both of the operating platform configuration and the associated locale, the desired font can be utilized in the operating platform.

  • Patent number: 8199364
    Abstract: When a second detector determines that a character image has a halftone (YES in #1) and a third detector (48) determines that a font size of the character image is equal to or greater than a threshold value ? and equal to or smaller than a threshold value ? (YES in step #4), a fourth detector determines whether a presently focused pixel constitutes a particular portion of a character (step #5). When the fourth detector determines that the pixel data of the presently focused pixel constitutes the particular portion of the character (YES in step #5), the image processing section sets the pixel data to be subjected to a second screen processing which is performed at a higher gradation level (step #6).

    Abstract: Methods and apparatus, including computer program products, implementing and using techniques for rendering a glyph to make it more readable. In an implementation, a glyph associated with a font to be rendered at a size is received, and a set of initial density values is calculated to provide one density value for each of a set of device pixels to represent the glyph. An initial adjustment value is calculated for the glyph. For one or more of the device pixels in the set of device pixels, a length of an edge of the glyph that passes through the device pixel is calculated. For one or more of the device pixels, the initial density value is adjusted by a final adjustment value, the final adjustment value based upon the initial adjustment value and the length of the edge of the glyph passing through the device pixel.

  • Patent number: 7492366
    Abstract: A method and system for optimizing the horizontal spacing of superscripts and subscripts in open type font designs is disclosed. The system includes a module for vertically aligning and spacing characters and a module for horizontally aligning characters having differing baselines in accordance with cut-in information stored in font tables corresponding to each individual character in the font. This additional horizontal spacing adjustment capability provides for optimum placement of character glyphs having differing baselines, e.g., superscript or subscript. The method includes placing a first/next character on a baseline, retrieving a next adjacent character, determining whether a cut-in associated with one or both of the characters can be applied between the two characters, and then applying the appropriate cut-in. Ascertaining whether a cut-in may apply may be accomplished by evaluating relative positions of adjacent glyph bounding boxes.

  • Patent number: 7408555
    Abstract: Methods and apparatus implementing and using techniques for rendering a stroke (e.g., a line or glyph). An initial adjustment value can be calculated for the stroke, and an offset amount calculated based on the initial adjustment value, such that a minimum number of device pixels will be marked by the stroke after adjusting density values of device pixels representing the stroke. A high resolution representation of the stroke (e.g., a set of device pixels each having an initial density value) is rendered so that one or more edges of the stroke is offset from a device resolution grid by the offset amount. A length of an edge of the stroke that passes through a device pixel can be calculated, and the density value of the device pixel adjusted by a final adjustment value based on the initial adjustment value and the length of the edge of the stroke.

An image writing apparatus analyzes commands identical in information content to character string information to which an input instruction has been issued. The analyzed support commands are all written onto a nonvolatile memory through a card drive. On the other hand, an electrophotographic image processing apparatus searches a DPOF file on the nonvolatile memory for all commands through a card read drive. From among the searched commands, a command that the electrophotographic image processing apparatus can support is extracted as a target command for the electrophotographic image processing apparatus.

  • Patent number: 6717580
    Abstract: The invention provides basic 1-to-1 character case mapping information for Unicode characters while using only small amount of memory and at a reasonable speed. The presently preferred embodiment of the invention provides a technique that encodes the case mapping into a sequential list of <Minimum, Size, Gap, Offset> quadruple. Every quadruple represents a range of characters. The Minimum and Size values represent the boundary of the range. The Gap represents which characters in the range have the valid mapping. Thus, if the character Minimum is a multiple of the Gap, then the character has a mapping in the quadruple. Otherwise, the character does not have a mapping. If the character has a mapping, then the mapped value is the character plus the Offset.
