Abstract:
A method for rasterizing a text character, based on character information, to be rendered on a display device having pixels each having a plurality of separately controllable pixel sub-components of different colors, the method comprising steps of:scaling the character information corresponding to the text character in the horizontal direction based on a horizontal scale factor to define rows of source sub-pixels; and converting the rows of source sub-pixels to a bitmap image in which the pixel sub-components of the display device are to be treated as independent luminous intensity elements, wherein the step of converting the rows of source sub-pixels includes a step of accessing N-bit chunks of source sub-pixels, where N is an integer greater than one and wherein the N-bit chunks of source sub-pixels are offset by a left side bearing remainder that corresponds to the remainder of a left side bearing of the text character divided by the horizontal scale factor.
