Transparency
You can select one color in your picture to become transparent when that picture overlays another picture. The color you select for transparency becomes invisible, allowing you to see through those pixels to the lower picture.
To set transparency attributes:
1. Click Modify and then, in the Picture group, click the arrow next to 
Color.
Color.2. Click Transparency.
3. Click any of the following:
◦ Click On and select the picture.
If the picture has a transparency color, the color becomes invisible during overlay.
◦ Click Off and select the picture.
If that picture has a transparency color, the color does not become invisible (default setting).
◦ Click Color.
The Select Color dialog box opens. In the Color box, select a color and click OK. Select the picture to apply the selected transparency color to it.
 | Transparent picture attributes must be set by Creo Elements/Direct Drafting. Attributes from other programs such as those written in jpg, tiff, etc. are not supported. All imported files are opened as non transparent. |
