uCrop is an Android library that allows you to crop images for further use. Its key features include:

- scaling images

- rotating images

- changing crop aspect ratio

- supporting touch gestures: scroll (pan) image with one finger, rotate image with two fingers, pinch to zoom, double tap to zoom

- out-of-the-box Activity with functional design, neat widgets for more precise image rotation and scaling, and a set of pre-defined common aspect ratios (1:1, 4:3, 3:4, 2:3, 3:2, 16:9, 9:16 + aspect ratio of the original image).

uCrop has a builder-type interface for initialization and for setting a proper configuration in your app.

While the library itself requires a minimum of API level 10, the sample works with API level 15+.
