Abstract
Apparatus, methods, and computer program products are disclosed that provides fast and accurate means of mapping one data space into another by precisely mapping grid points between the data spaces and then by performing a bilateral-bilinear interpolation to map the points bounded by the precisely mapped grid points. The precisely mapped grid points define boundary lines that bound a data region in a source: space. Each scan line mapped to the source space is dependent on the slopes of the bounding lines of the data region.
