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