Chapter 8 for photographs apply also to clip art. You can move, resize, increase or decrease brightness and contrast, rotate, and so on. But there are also some special modifications you can make that apply only to clip art and other vector images. The following sections explain them.
Recoloring an Image
One of the top complaints about clip art is that the colors are wrong. Maybe you've found the perfect drawing, but its colors clash with your presentation design? Not a problem. In most cases you can change any or all of its colors.
| Caution | You cannot recolor a raster graphic such as a scanned photo in PowerPoint. Re-coloring works only on vector graphics like clip art. Some third-party image-editing applications allow you to replace one color with another in a raster graphic, however. |
A piece of clip art consists of a series of lines and filled shapes, much like the AutoShapes from Chapter 7. Recoloring changes the colors of the lines and/or fills on a color-by-color basis.
To recolor a clip, do the following:
Select the clip that you want to recolor. If the Picture toolbar does not appear, display it.
On the Picture Toolbar, click the Recolor Picture button. The Recolor Picture dialog box appears showing all the colors used in the image (see Figure 9-12).
Choose Colors or Fills at the bottom of the dialog box. Colors (the default) shows all the colors in the image, both the lines and the fills. The Fills option, on the other hand, shows only the fill colors.
Click the checkbox next to one of the Original colors. Then, open the New drop-down list next to it, and select a color to change it to.
The preview will update automatically. Drag the dialog box out of the way as needed so you can see the change in the image on the slide itself.
Repeat steps 4 and 5 for each of the colors you want to change. If you change your mind about a color, deselect its checkbox to retain the original.
Click OK to finish.

Deconstructing and Editing a Clip
Have you ever wished you could open a clip art image in an image-editing program and make some small change to it? Well, you can. And what's more, you can do it without leaving PowerPoint.
Since clip art is composed of vector graphic lines and fills, you can literally take it apart piece by piece. Not only can you replace certain colors (as in the preceding section), but you can choose individual lines and shapes out of it to recolor, move, or otherwise modify.
To deconstruct a piece of clip art:
Select the clip, and then on the Drawing toolbar, choose Draw⇨Ungroup. A warning message appears that this is an imported graphic, not a drawing, offering to convert it to a Microsoft Office drawing.
Click Yes to convert the clip to a Microsoft Office drawing. It will still be grouped at this point.
Choose Draw⇨Ungroup again. This time the drawing is broken apart into lines and shapes, with each one having its own selection handles (see Figure 9-13).
Click away from the clip to deselect all the selected pieces, and then click once on the piece you want to work with.
Move it, resize it, change its color, or do any other editing to it desired, as you learned in Chapter 7. For example, in Figure 9-14, I've recolored a few of the parallelograms that represent windows on the building so that it looks like the "lights" are on for a few of the offices on the top floor.
When you are finished editing the clip, regroup it. To do so, click any of the individual components on the clip and then choose Draw⇨Regroup.
Figure 9-13: This clip comprises many tiny lines and shapes, each with its own round white selection handles and green rotation handle.
