The only way I'm aware of will allow rectangular clips only: display your
source image in a group or a button, and then change the group's or button's
rect.  I believe there's no built-in way to create oval or irregular masks.

However, a more involved (read: painful) way to do this type of masking
would be to show your image in a separate window and mask the window.  On
MacOS you'll need the Odo WDEF and on Windows you'll need Tuviah Snyder's
external collection.  Like I said, major effort involved, but possible.
