"""Provides implementations of basic image processing functions.
Implements basic image processing functions, such as reading/writing images,
cropping, finding the bounding box of a color and diffing images.
When numpy is present, image_util_numpy_impl is used for the implementation of
this interface. The old bitmap implementation (image_util_bitmap_impl) is used
as a fallback when numpy is not present."""
