B4i Library SD: ImageCrop

This new library will allow you to make cuts on images in a square (rectangular), circle and ellipse.
Moreover, the image can be enlarged by the user, and rotated to obtain different cuts.
I have used XUI libraries, if I have time I convert it to Android.

The full version will be distributed to those making a donation. You can contact me in private.

I have attached in the first post, the demo version and an example.

In the future I will add a ring to rotate the image that will allow you to understand how many degrees you are rotating and a similar method for zooming
