An OverlayBitmap object contains the overlay data, methods and properties for drawing text and graphics on the live video stream.

Example

[C#]
OverlayBitmap ob = ICImagingControl1.OverlayBitmapAtPath[PathPositions.Device];
//   Enable the overlay bitmap for drawing.
ob.Enable = true;
//   Set magenta as the dropout color.
ob.DropOutColor = System.Drawing.Color.Magenta;
//   Fill the overlay bitmap with the dropout color.
ob.Fill(ob.DropOutColor);
//   Print some text in red.
ob.FontTransparent = true;
ob.DrawText(System.Drawing.Color.Red, 10, 10, "IC Imaging Control 2.0");
