Methods and systems for scaling and rotating an image in a single operation

摘要

A method of scaling and rotating an image includes generating a scaled and rotated pixel grid from a transformation operation applied to an input pixel grid. The input pixel grid comprises a plurality of pixels representing an original image, and the transformation may implement the simultaneous scaling and rotation of the input pixel grid. The respective values of a plurality of output pixels in the scaled and rotated pixel grid are then determined by interpolation.
