Abstract:
In a computer having a display device on which images are displayed, the display device having a plurality of pixels each having a plurality of separately controllable pixel sub-components of different colors, the pixel sub-components forming stripes on the display device, a method of rasterizing image data in preparation for rendering an image on the display device, the method comprising the steps of:scaling image data that is to be displayed on a display device by a first factor in the direction parallel to the stripes and by a second factor in the direction perpendicular to the stripes; adjusting selected data points of the scaled image data to grid points on a grid defined by the pixels of the display device, at least some if the grid points having fractional positions on the grid in the direction perpendicular to the stripes; scaling the hinted image data by an overscaling factor greater than one in the direction perpendicular to the stripes; and mapping spatially different sets of one or more samples of the image data to each of the pixel sub-components of the pixels.
