| <p> |
| The shapewipe element provides custom transitions on video streams |
| based on a grayscale bitmap. The state of the transition can be |
| controlled by the position property and an optional blended border |
| can be added by the border property. |
| </p> |
| <p> |
| Transition bitmaps can be downloaded from the |
| <a class="ulink" href="http://cinelerra.org/transitions.php" target="_top">Cinelerra transition</a> |
