Mask with PowerPoint: Part I

Published Sat, Apr 22 2006 20:04
If you have seen how Macromedia Flash masks objects and animating them using layers, you will know that it is not possible with PowerPoint. But are these masking effects really impossible with PowerPoint? The answer is no. There are several methods and workarounds that you can use to create the masking effects. Up till this point, if you are still unclear with what masking is, below shows some pictures of how masking works.

Figure 2: Glow mask a text in PowerPoint.

Figure 3: Masking a picture in PowerPoint.

This tutorial will be separated into several parts. Today, we will learn how to mask a text or WordArt in PowerPoint.

As shown in Figure 1, you want to mask a text. The initial background is black in color. Next, you see a white circle moving around the screen, revealing a text black in color. The solution is simple. The background is black, the text is black, and the circle is white. Still don't get it? We just need some ordering.

First, click Format > Background. Click on the dropdown field and set the background to black.
Next, draw a circle AutoShape and set the color to white.
Finally, make a textbox and type in some words.

Make sure that the ordering are right. The white circle must be at the back, while the text is at the front. This will create the masking effect as shown in Figure 1. How about background with gradient, picture, or texture?

Same method. But instead of making a textbox, create an WordArt this time round.
First, click Insert > Picture > WordArt.
Select the first style, and type some text. Click Ok.
Now select the WordArt you have created.
Click Format > WordArt.
Under the Fill section, click on the color dropdown field, and select Background. By doing so, the WordArt will follow the background on the slide.
Next, under Line section, click on the color dropdown field and set the line color to No Line.

Now, you can animate around on the AutoShape to create some interesting animations. Examples will be to add motion paths and grow/shrink (Emphasis) effects onto the AutoShape.
