Abstract: The principles of the present invention relate to rendering stroke pairs. A graphical object includes at least a first stroke and a second similarly oriented second stroke collectively representing a stroke pair. A calculated distance between the first stroke and the second stroke is constrained (e.g., to a center line between the strokes) to mitigate the possibility of rounding errors causing the represented stroke pair to be inappropriately rendered. After the stroke pair is constrained, controls points of the individual strokes can be adjusted so that the individual strokes are appropriately rendered at their respective constrained locations. The adjusted stroke pair is constrained between external reference points for appropriate rendering relative to other graphical objects. The graphical object, including the adjusted constrained stroke pair, is rendered at an output device.

The system may project the video images on a surface around the person and may move the projected video images on the surface based on a movement of the person. The projected video images may include computer-generated characters and/or virtual objects that react to the movement of a person.

Abstract: A method for creating a coordinated image display by designing a digital template for the image display. The template includes a number of openings for displaying digital images.

Third, each stroke/glyph forming the set of characters is redefined, with key points and/or width values of the stroke/glyph are adjusted according to predefined rules, to thereby form a redefined set of characters. Fourth, the redefined set of characters are rendered according to predefined rendering criteria.

Abstract: A multiple font management system and method in a printing device for activating multiple fonts is provided for enabling base font localization and font patching for print jobs to reduce the need to upload entire fonts in order to provide localized receipts or to provide corrections to partially-corrupted font tables. A font access level stores locations of activated base, localization and patch fonts and are referenced in an access order during character retrieval so as to apply retrieval priority to patches and localizations. A font storage level maintains multiple tier character indices for referencing character shape data in order to provide faster character searching through each of the multiple activated fonts than a single-level index.

Abstract: A method aligns a character to a sampling grid of an image. An original uniform width path that traces a skeleton of the character is specified by input pen commands having original coordinates. The width of the original path is rounded to a nearest integer to produce a hinted width. The original path is traversed using the input pen commands to identify segments of the path. The segments are stored in an array. Hinted coordinates are determined for each segment in the array. The array is sorted, and a directed acyclic graph (DAG) is constructed. Collisions between the segments are resolved using the sorted array, the DAG, and the width of the hinted path. The segments are fitted to the sampling grid, and the result is stored in output pen commands, thereby aligning the skeleton of the character to the sampling grid.

Abstract: Data tables that are required for the proper processing of font glyphs are automatically synthesized if they do not form part of an original font definition.

Therefore, the printing data can be precisely and easily prepared, without the work efficiency of a user being deteriorated.

Abstract: A method of rendering text on an output device using a pre-developed image of a custom font. An image file defines an image of a custom developed character set. The custom character set may be developed off-line using graphics development tools. Associated character information enables the location of specific characters within the image. When a text character is output to a display or other output device, a custom font module locates the text character within the image and defines a subimage that contains the text character. The subimage is rendered upon the output device, thereby producing an image of the text character.

When the in-operation flag is set as “ON” and a second object is within a predetermined distance from an input position of the pointing device, the second object is selected. When the in-operation flag is set as “OFF”, that is, when the player stops controlling the first object, the first object is caused to perform a process for exerting an effect on the second object having been selected.

Abstract: An information-processing device (such as an image-processing device) executes a boldface character generating process when it is judged that a character should be expressed in boldface type based on a drawing instruction inputted from outside and there exists no boldface form data of the character corresponding to font information comprised in the drawing instruction. In the boldface character-generating process, the information-processing device generates pattern data lacking at least one dot at each of the four corners and generates the boldface form data by enlarging the drawing area of bitmap data (generated from standard form data) based on the pattern data. The at least one missing dot at each of the four corners of the pattern data, allows edges of the generated boldface character to be expressed finely even when the boldface character is generated from a character having an oblique element (oblique line, curved line, etc.).

The glyph has an outline that has an outside path. In one aspect, a method includes identifying four extrema points of the outline, each being an intersection of two vectors obtained from the outline; and for each of the points, calculating a cross product of the two vectors intersecting at the point.

The winding order of the outside path is determined based on the cross products calculated. In a particular implementation, the method determines that the outside path is wound counter clockwise when three or four of the results are positive.
