Transformation

abstract class Transformation

An interface for making transformations to an image's pixel data.

NOTE: If ImageFetchResult.image or DecodeResult.image is not a BitmapDrawable, it will be converted to one. This will cause animated drawables to only draw the first frame of their animation.
