                                   FastPatternSampler

A fast-n-dirty pattern sampler using Python Imaging Library routines. Currently this sampler doesn't support user-specified scaling or cropping but rather simply scales and crops the image to fit the given matrix size without distorting the aspect ratio of the original picture.
