After subtracting, make the resulting mask opaque again. But make it semi-transparent while you’re adding the smaller shape so you can see where to put that smaller shape. This technique is the same except that the large rectangle is opaque. I found 0.75 seconds to be about right.Įxample 2: Full mask (everything else is opaque) (In 2007, choose Animations tab> Custom Animation and then choose Add Effect.) You might want to change the timing to make it slower. If you don’t see it, click More Entrance Animations at the bottom of the list.

For example, click the Add Animations button and choose Zoom from the Entrance animations. With your lightbox selected, click the Animations tab and choose the animation you want.(Note that the feature is available in PowerPoint 2010 and later and is not easy to find in PowerPoint 2010 see the blog post for a link to more information about that.) For PowerPoint 2007, you can use the Set Transparent Color feature. I explain in an older tips on masks called Create Cutouts. I explain that feature in more detail here. On the Format tab, choose Merge Shapes, Subtract. Select the rectangle, then press Shift and select the oval.Then move and resize it so it covers the right area of the slide. As you did with the rectangle, make it semi-transparent if you need to see exactly what to cover. Draw an oval (or any shape) over the area you want to emphasize.I chose a medium gray, but you could use white.

In the Fill area, set the rectangle to about 50% transparency.
