Abstract
Methods and apparatus for managing a source image that is output in a rotated or skewed orientation to a raster buffer. The source image includes a plurality of source samples arranged in source rows having a source direction. The raster buffer is oriented in a destination space and receives the rotated or skewed image as a series of samples in rows defined by a destination direction. The raster buffer provides rows of samples to a rendering device for rendering scan lines for output on a raster device. The method includes determining an angle between the source direction and the destination direction and adjusting the organization of the source samples to align source samples in scan rows where each scan line can be rendered from the raster buffer using at most a predetermined small number of scan rows.
