How to clear overlay line

[Sandor]

I would like to clear a line drawn using IMAQ Overlay Line without clearing all overlays (using IMAQ Clear Overlay).  I tried using Overlay Line with the Transparent color (using the same line coordinates) and this did not work.  Anyone have any suggestions?

Thanks

A simple trick is to copy the overlay to another empty image, and to copy back this overlay to erase any posterior modification. The attached vi demonstrate this solution. An alternative would be to construct an array in witch all the additions to the overlay would be stored, and to redraw the overlay from scratch using this array.
