  • Patent number: 8814677
    Abstract: Techniques are described for providing a painting and thinning mechanic within a computer-generated environment (e.g., in a video game). The painting and thinning mechanic allows geometry within the computer-generated environment to be “painted” or “thinned.” Painting and thinning refers to a mechanic that involves making parts of the virtual environment visibly and collidably transparent (thinning) or visibly and collidably opaque (painting). The painting/thinning mechanic may be achieved using binary space partitioning (BSP) trees.

  • Patent number: 8819543
    Abstract: An object including at least one element is moved on a document in which the object is arranged in response to an instruction from a user. In addition, if the object is moved to a boundary between two pages, at least one element that is included in the object and that corresponds to a break position of the two pages is detected. Then, a position where the at least one detected element is arranged in the document is determined so that the element is arranged in either of the documents of the two pages and an image corresponding to the document is output. In the above manner, it is possible to appropriately arranging elements in a document to output an image corresponding to the document having the elements appropriately arranged therein.

  • Patent number: 8031204
    Abstract: Systems and methods used for bilinear texture filtering may also be used to perform font filtering. Font data stored as a texture is read from memory in blocks that are coarsely aligned. Font alignment units may be used to provide a finely aligned region of the font data within a font filter footprint. The finely aligned region is then filtered using bilinear filtering to produce font coverage information representing a grayscale value for a pixel. Using existing bilinear filtering engines in conjunction with font alignment and sample units reduces the need for having a specific engine to perform each of the font filtering operations, possibly saving die area in a graphics system.

  • Patent number: 7970812
    Abstract: A system and method for redistributing space in ink-to-text conversions is described. In stylus-based computing systems, users often desire to convert ink from ink into text. Sometimes the conversion is made such that an interaction region is made too small for effective recognition correction or interaction. A system and procedure is described that adjusts the spacing of text to allow easier interaction with the recognition results.

  • Patent number: 7965422
    Abstract: A system facilitates printing of microtext. A processing component allows a user to create one or more microtext characters, wherein the characters are output as a data packet. An SRE code store receives and associates one or more SRE codes with the data packet, each SRE code is representative of a bit pattern, wherein the bit pattern is a grid of bits that are filled to create a particular pattern. A font bank receives the one or more SRE codes from the SRE code store and defines such codes via a font. A raster image processor receives the font from the font bank, decodes the font and outputs instructions to print the microtext.

  • Patent number: 7907141
    Abstract: A method and process provides structure recognition to a node-link diagram formed by a plurality of digital ink strokes drawn on a canvas of an electronic device by an input device. The method and process include grouping related strokes into multiple hypotheses reflecting structure interpretations of the strokes in a group. Confidence scores are computed for the multiple hypotheses based on local evidence regarding the strokes of the stroke groups and surrounding strokes. Constraints are applied among the hypotheses, and a collectively high scoring assignment of accept/reject values of the hypotheses are determined under the applied constraints. The hypotheses with collectively high scoring assignments are accepted as a representation of the node-link diagram, where structure information is provided to the strokes of the node-link diagram, making the node-link diagram electronically editable.
