Creating a mask effect in PowerPoint is easy, once you’ve located the Shape Combine command. You can add this command to the Ribbon or the Quick Access Toolbar.
Below, you see it being added to my toolbar.
Adding the Shape Combine Command to the Toolbar, alternately look for the Combine Shapes command as more options are available.The command will not be active until there are two shapes selected. Below, I’ve created a blue rectangle and a red oval. The oval shape will be cut out from the rectangle.
Blue rectangle with red oval positioned for the cut out. You may prefer to add the Combine Shapes command instead. More options are available as you can see below.
The result of the Shape Combine command, a rectangle with an oval “hole: in the center.
The result of the Combine Shapes CommandOnce the mask is created, you can dress it up. Below, I’ve changed the fill to an image of a leafy forest floor.
The forest floor has a hole in it. Now I can layer whatever image I wish (in this case a frog) under the mask. You can animate the layer underneath the mask. Can you image a wheel of creatures rotating into the viewpoint in the center of the mask? That would be great for a talk about ecology!
