摘要： A method and system for matching digital information flow to the human perception system. In various embodiments, multi-monitor (multimon) support is leveraged to take advantage of multiple windowing and window positioning to separate elements of different tasks into information planes (which are based on a concept of “triage and focus”). Triage watches the flow of incoming information and determines the nature of the information. Based on the nature of the information and principles of human perception, Focus (or defocus) displays the information where the information is best viewed.

摘要： Image data processing and image rendering methods and systems whereby images are displayed on display devices having pixels with separately controllable pixel sub-components. Images, such as text characters, are displayed on a display device with at least some features being rendered with sub-pixel precision. The displayed advance width of a character displayed with sub-pixel precision is compatible with the advance width of the character if it had instead been displayed with a conventional full pixel precision rendering process. Thus, characters are displayed with sub-pixel precision, resulting in improved resolution and readability, while the advance width and the corresponding size and spacing of the characters and the overall formatting of the document remains the same compared to documents and characters rendered using conventional full pixel precision processes. The sub-pixel precision rendering process also involves mapping spatially different sets of one or more samples of the image data to individual pixel sub-components rather than to full pixels.

摘要： Methods and apparatus for rendering and/or displaying images such as text using sub-pixel accuracy are described. In various embodiments, character advance width is determined using pixel precision while left side bearing and/or black body width is determined using sub-pixel precision. Such embodiments provide for characters with overall widths corresponding to pixel widths but with the character black bodies being positioned within the overall character space to a higher degree of position than when pixel precision is used. In other embodiments, sub-pixel precision is used for determining a character's overall width as well as left side bearing and black body width values. In such embodiments, black body starting points and left side bearing points are aligned with sub-pixel component boundaries. By treating R, G, B pixel element sub-components as independent luminous intensity sources and by using pixel sub-component accuracy for character width, spacing and positioning, overall image appearance is enhanced as compared to embodiments which use pixel precision for character width, spacing and positioning values.

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 systems are disclosed for utilizing an increased number of samples of image data, coupled with the separately controllable nature of RGB pixel sub-components, to generate images with increased resolution on a display device. such as a liquid crystal display. The methods include scaling, hinting, and scan conversion operations. The scaling operation involves scaling the image data by factors of one in the directions perpendicular and parallel to the RGB striping of the display device. Hinting includes placing the scaled image data on a grid that has grid points defined by the positions of the pixels of the display device, and rounding key points to the nearest full pixel boundary in the direction parallel to the striping and to the nearest fractional increment in the direction perpendicular to the striping. Scan conversion includes scaling the hinted image data by an overscaling factor in the direction perpendicular to the striping. The overscaling factor is equivalent to the denominator of the fractional increments of the grid. Scan conversion also includes generating, for each region of the image data, a number of samples that equals the overscaling factor and mapping spatially different sets of the samples to each of the pixel sub-components.

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： Optimizing objects output to a user. One method includes accessing a reference object of a character representing an idealized output. A different representation of the reference object is accessed. The reference object is compared to the representation of the reference object to generate an error metric. An optimization is applied to the representation of the reference object. The optimization is directed to causing the representation of the reference object to more closely approximate the reference object. Comparing objects and applying optimizations is repeated until an acceptable representation of the reference object is achieved. The acceptable representation of the reference object is displayed.
