Abstract:
1. In a processing device associated with a display device that has a plurality of pixels, each pixel having a plurality of separately controllable pixel sub-components, a method of rendering an image using an anti-aliasing filter selected from a plurality of anti-aliasing filters based on the font size of a character of the image, comprising the acts of: storing a data structure that defines a plurality of different anti-aliasing filters; identifying the attributes of an object of the image to be rendered; selecting, based on the identified attributes, an anti-aliasing filter from among the plurality of different anti-aliasing filters, wherein at least two of the plurality of different anti-aliasing filters operates by calculating a weighted sum of adjacent samples of image data that represents the image, wherein the amount of anti-aliasing provided by filters selected based on a relatively larger object body thickness is greater than the amount of anti-aliasing provided by filters selected based on relatively smaller object body thickness, wherein the number of adjacent samples, which are used by the anti-aliasing filters used to calculate the weighted sum, increases as the body of the object thickness corresponding to the anti-aliasing filters increases; and applying the selected anti-aliasing filter in a direction parallel to striping of the pixel sub-components.
