 #### Inverse
 
 We have briefly shown how this option is used in [our tutorial on image transformations](../tutorials/applying-transform-function-on-images.md). Let's take a deeper look at it.

 This is particularly useful for rotations, where corners of the image may extend beyond the original boundaries.
