SUMMARY
PowerPoint 98 supports transparency in bitmapped images. If you insert a bitmap into a slide, you can make one of its colors transparent. In addition, if your bitmap already has transparency, and it is in one of the following graphic formats, it appears transparent when you insert it into your slide:
 * CompuServe Graphics Interchange Format 89a (GIF)
 * Portable Network Graphics Format (PNG)

NOTE: If you insert a Tagged Image File Format (TIFF) or TARGA (TGA) image into a slide, PowerPoint ignores the transparency information.



MORE INFORMATION
To make part of your image transparent, use the set transparent color feature. To do this, follow these steps:
 * 1) On the Insert menu, point to Picture, and then click From File.
 * 2) Select the graphic file you want and then click Insert.
 * 3) If the Picture Toolbar does not appear, right-click the graphic and then click Show Picture Toolbar on the menu that appears.
 * 4) Click the Set Transparent Color button.
 * 5) Click a part of the graphic that is the color you want to make transparent.

This method is ideal for color images that were created by a graphics program or for black and white images that were scanned. It may not work well with color images that were scanned. These images often have very subtle color changes. For example, the apparently black background of a scanned picture of the Earth may actually consist of several colors of very dark gray. In this case, if you try to mask out the background, you may still see some dark streaks after you set the transparent color.
