I use IC Imaging Control 3.0 with .NET 2005. In an overlay I draw in almost every new frame an ellipse at a different coordinate. Drawing the points works fine. My problem is, that the overlay from the previous frame should be deleted (not displayes anymore).

Is there a possibility?

Kind regards,
Silvan Zuppiger

Hi Silvan,

Yes, it is possible. Please refer to:

At least you may fill the entire Overlaybitmap with the dropout color or you simply redraw your drawings with the dropout colors before drawing them on a new position. Please refer to:
