1. A computer-implemented method to perform image transformations in an imaging device, the method comprising: receiving one or more transformations of translation, rotation, scaling, and shear with at least one of: an affine composite transformation matrix; and discrete values obtained from a polar decomposition of a composite transformation matrix; applying the transformations to at least one of: an imaging subsystem in an image path of the imaging device, the transformations being image transformations; and a paper subsystem in a paper path of the imaging device, the transformations using discrete values.
