# shapewipe

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.

Transition bitmaps can be downloaded from the Cinelerra pages here or here.

## Example launch line

     gst-launch-1.0 -v videotestsrc ! video/x-raw,format=AYUV,width=640,height=480 ! shapewipe position=0.5 name=shape ! videomixer name=mixer ! videoconvert ! autovideosink     filesrc location=mask.png ! typefind ! decodebin ! videoconvert ! videoscale ! queue ! shape.mask_sink    videotestsrc pattern=snow ! video/x-raw,format=AYUV,width=640,height=480 ! queue ! mixer.

This pipeline adds the transition from mask.png with position 0.5 to an SMPTE test screen and snow.
