Question: how to use center-crop, but not from the center , but from a different point?

[AndroidDeveloperLB]

Is there something similar to center-crop, yet I have the choice where to focus in terms of specific point/rectangle in the bitmap? I want to make sure a specific point/rectangle is shown while fitting&cropping. How can I do it? Currently the only similar thing that exists officially for ImageView is center-crop, but it's only to the center. What if the most important part in the image is at the bottom, instead? Or 10% (or 10px) from the bottom, etc... ? Or if there is a specific region in the bitmap that's most important?
