摘要： Methods, systems, and computer program products for adding hinting instructions to a character in order to improve a character bitmap produced from an outline of the character at a certain size and output resolution when the character outline is scan converted. A character is retrieved to be output. A determination is made that the character belongs to a semantic character classifications, and hinting instructions that are associated with the semantic character classification are accessed. The hinting instructions preserve semantic meaning for the character while altering either stroke presence, stroke location, or both for at least one stroke of at least one feature of the character based on a reference character size and output resolution. If the actual character size and output resolution for the character is within a reference character size and output resolution for the hinting instructions, the hinting instructions are executed.

摘要： Mechanisms for rendering an object on a portion of a display that includes pixel sub-components for each pixel. The pixel sub-components are striped along a certain direction (e.g., vertically or horizontally). The computing system determines that the object has spatial frequency dominance a direction which happens to be parallel to the striping direction. The computing system then performs sub-component based sampling assuming that the striping direction is perpendicular to the actual striping direction. Then the object is rendered on the display. This may be performed for each object to be displayed. Counterintuitively, this improves the resolution of the character being displayed as compared to performing pixel sub-component based sampling assuming that the striping direction is the same as the actual striping direction.

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： 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 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： The principles of the present invention relate to dynamically determining directions of freedom for control points used to represent graphical objects such as text. A computing system identifies a first function that represents a first constraint, solutions to the first function indicating compliance with the first constraint. The computing system calculates, based on the location of a control point and the identified first function, that the control point does not comply with the first constraint. The computing system automatically determines a first direction of freedom in which the control point can be moved to comply with the first constraint such that movement of the control point in the first direction of freedom has a reduced likelihood of causing non-compliance with other constraints.

摘要： The principles of the present invention relate to appropriately rendering a graphical object when a corresponding outline lacks necessary control points. A computer system calculates the target width for a feature of the graphical object. The computer system calculates the position of a center line corresponding to the feature. The computer system rounds the calculated position of the center line to a grid position based on the calculated target width for the feature. The computer system adjusts the position of one or more control points of the feature to comply with the grid position of the center line.
