Class FastImageSampler

source code

A fast-n-dirty image sampler using Python Imaging Library routines. Currently this sampler doesn't support user-specified size_normalization 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.
