How would I display a partial image on a canvas in the new UI system?

Hey!

So, I think my question covers it. I have some images that I am using for my UI that are using the new Unity UI system so… images put on a canvas. Occasionally I want to only display say… the left 25% of an image only, etc. How would I go about doing something like this?

Use the UI Mask. Check out this video for a tutorial.
