Method and apparatus for displaying anti-aliased text

摘要: The present invention provides a method and apparatus for displaying anti-aliased text. Text on computer display device typically contains "jaggy" edges (referred to as aliased text). of the smoothes such by blending text into color background is being rendered on. A mask or alpha channel created through which rendered. drawing at larger size (typically 4 times size) shrinking image down using an outline vector extraction method. used blend bitmap representation background. utilizes run-length compression encode data. Additionally, avoid need original bitmap, encodes information data, creating unique bitmap/mask hybrid. Due creation storage hybrid bitmap/mask, memory requirements are significantly decreased. Further, when rendering text, run length ability ignore/skip multiple pixels. Consequently, mixing with source
