Clicking the Mask button applies a clipping mask to the image in the shape and size of the
image. In this case, the image itself does not look any different.
Tip
You can also apply a clipping mask by choosing Object > Clipping Mask > Make.
- In the Layers panel, click the Locate Object button ( ) at the bottom of the panel.
Notice the <Clipping Path> and <Image> sublayers that are contained within the <Clip Group>
sublayer. The <Clipping Path> object is the clipping path (mask) that was created, and the
<Clip Group> is a set that contains the mask and the object that is masked (the cropped,
embedded image).
