The image object is a bitmap.

There is no direct polygonal masking in Rev like there is in SC, but in some
cases you can use a combination of inks and a group to achieve the same
effect.  You group the polygon graphic and image, and apply certain inks to
the polygon and the group itself.  The formula might change depending on the
background of card/stack, but that's one way to do it.
