摘要： The present invention provides for automatic placement of typographical features such as vertical stems or horizontal segments of a character on high contrast pixel sub-component boundaries as part of a rendering process that uses separately controllable pixel sub-components of pixels to represent different portions of the character. In order to identify the typographical features of the character that are to be aligned with high contrast pixel sub-component boundaries, topology of the character is analyzed at runtime. In display devices having vertical stripes of same-colored pixel sub-components, it has been found that character legibility is increased when the left edges of stems are aligned with high contrast boundaries between pixel sub-components. Processing time and resources are conserved by performing a partial, rather than a full, topological analysis of the character. For example, some font files include data structures that define the position of key control points associated with the character, thereby indicating where the stems or other typographical features are located, and the relationship between different typographical features.

摘要： 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.

摘要： The principles of the present invention relate to iteratively solving constraints in a font-hinting language. A computing system accesses a more complex constraint that can not be natively expressed based on the vocabulary of the font-hinting language, the more complex constraint constraining at least a portion of the outline. The computing system decomposes the more complex constraint into a plurality of simpler constraints that can be natively expressed based on the vocabulary of the font-hinting language. The computer system represents each of the simpler constraints in corresponding font-hinting language instructions that can be iteratively processed to at least approximate a solution to the more complex constraint. The font-hinting language instructions are iteratively processed at the computing system or another computing system to cause a graphical object to comply, within a specific tolerance, with the more complex constraint.

摘要： Methods and apparatus for utilizing pixel sub-components which form a pixel element of an LCD display as separate Red (R), Green (G), and Blue (B) luminous intensity values. R, G, and B luminous intensity level values are generated as part of a weighted scan conversion operation and are packed into 8 bit values thereby avoiding the need to store, transmit and process separate R, G and B luminous intensity values representing character glyphs. A look-up table including packed pixel values and processed pixel values is used to convert between glyphs represented by the packed pixel values and R, G, and B pixel sub-component values in a format used by the display. In various embodiments the processed pixel values represent the result of performing unpacking, gamma correction, color filtering and color palette selection operations using the packed pixel values as input.

摘要： Validating a signed program prior to execution time or an unsigned program at execution time. A program is validated by checking the input parameters to the instructions of the program to prevent errors associated with executing an instruction using an invalid input parameter. Both signed programs and unsigned programs are accommodated. A signed program is validated during the signing process, whereas an unsigned program is validated at execution time.
