Abstract:
1. A method for snapping points of a visual element defined in accordance with a device-independent coordinate system to a device-dependent pixel grid to improve an anti-aliased rendering comprising the steps of: receiving a plurality of guidelines associated with the visual element, wherein each of the plurality of guidelines is defined in accordance with the device-independent coordinate system and is associated with an area of symmetry of the visual element; determining an offset required to align each of the guidelines with a nearest line in the pixel grid and storing each offset in association with its corresponding guideline in memory; snapping the points of the visual element to the pixel grid to create an adjusted image by accessing the memory to determine which guideline is closest to each of the points and then applying to each point the offset associated with the guideline that is closest thereto; and rendering the adjusted image on a display device.
