摘要： Among other things, one or more techniques and/or systems are disclosed for rendering a glyph. Rendering data for the glyph can be received, such as size, shape, color, etc., along with first sub-pixel position for initially rendering the glyph on a display. A first rendering quality can be identified for the first sub-pixel position and second rendering quality can be identified for a second sub-pixel position, which may comprise an alternate rendering position. A sub-pixel position shift can be selected for the glyph based at least upon a comparison of the first and second rendering qualities. The sub-pixel position shift can comprise a difference between the first sub-pixel position and the second sub-pixel position, where the second rendering quality is selected/preferable over the first rendering quality. The glyph can be rendered by applying the selected sub-pixel position shift.

摘要： One or more techniques and/or systems are disclosed for reducing font execution instructions for a font, and thereby a file size for the font. The font execution instructions can be scanned (e.g., by examining tables) to identify one or more common instruction sets in the font execution instructions. A function can be defined for a common instruction set, and the instances or appearances of the common instruction set in the font execution instructions can be replaced with a call to the function. Because the call is generally smaller (e.g., comprises fewer lines of code) than the common instruction set it replaces, the number of execution instructions for the font is reduced.

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.
摘要翻译： 本发明的原理涉及渲染笔划对。 图形对象包括集体表示笔画对的至少第一笔划和第二类似地定向的第二笔划。 第一笔划和第二笔划之间的计算距离被约束（例如，到笔划之间的中心线），以减轻舍入误差的可能性，导致所表示的笔划对被不适当地呈现。 在限制冲程对之后，可以调整各个笔划的控制点，使得各个笔划在它们各自的约束位置适当地呈现。 经调整的笔划对被限制在外部参考点之间，用于相对于其他图形对象的适当渲染。 图形对象，包括经调整的约束笔划对，在输出设备处呈现。

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： The present invention relates to dropout control in which one or more samples are added to adjacent samples that fall within an image outline. The samples are used in sub-pixel rendering to compensate for unnaturally thin or faint object stems. Horizontal dropout control operations are provided to add samples to sets of horizontally adjacent samples such that each set of samples comprises a minimum number of samples. Vertical dropout control operations are provided to position samples such that the weighted anti-aliasing filtering will take sufficient account of the samples. In one embodiment, an associative table is utilized to calculate alternative patterns of samples. In another embodiment, the baseline of an object is used in the dropout control operations to reduce artifacts that can be created by the addition of samples in the vertical direction.

摘要： Methods and systems for selecting different anti-aliasing filters to be applied to objects of image data rendered with pixel sub-component precision based on the attributes of the objects of the graphics image. For example, when rendering a character traditional anti-aliasing applied in the direction parallel to the striping of the pixel sub-components is adapted to the unique requirements of different character font sizes such that a large amount of anti-aliasing is applied to large font sizes while a small amount of anti-aliasing is provided for characters at small font sizes. Displaced sampling is utilized to determine the alpha values for a plurality of vertical samples for each RGB pixel sub-component. The selected anti-aliasing filter is applied to the alpha values to determine the luminous intensity values of the RGB pixel sub-components.

摘要： The principles of the present invention relate to appropriately rendering a graphical object when a corresponding outline has excessive control points. A computer system identifies a point of junction between a first and second feature of the outline. The computer system accesses an excess control point included in the first or second feature of the outline. The computer system moves the excess control point in a first direction until the position of the excess control point in the first direction is essentially the same as the position of the point of junction in the first direction. The computer system moves the excess control point in a second direction until the position of the excess control point in the second direction is essentially the same as the position of the point of junction in the second direction, the second direction being different from the first direction.

摘要： A damper/strut that can provide variable damping and spring energy storage and dissipation. One embodiment includes an adjustable magnetorheological damper and a mechanically adjustable fluid spring in association with an internal accumulator. A combination of internal and external electromagnets generate the magnetic fields required to activate internally maintained magnetorheological material so that its apparent viscosity undergoes the desired change for a given disturbance. By controlling the strength of the magnetic fields generated in the device, the damping capacity and energy storage of the compressible liquid spring can be affected to provide a semi-active damper that can both dissipate and store energy. The proposed devices can be coupled with a sensor feedback and a control system to provide fast and accurate response force for a variety of engineering applications.
