Abstract
A method and apparatus for scaling graphics data is begins by retrieving a line segment of graphics data from a frame buffer, or memory, which stores the graphics data in lines. Once the line segment of a current line has been retrieved, a corresponding line segment of another line is retrieved from a line buffer. The two line segments are then blended together to produce blended pixel information. The blended pixel information is then scaled and subsequently stored to produce a resulting graphics output. After the corresponding line segment has been retrieved from the line buffer, it is overwritten with the currently retrieved line segment.
