Detailed Description

Supported arithmetic or logic pixel-wise operators.

Remarks:

(*) Not applicable for the BW1 images/ROIs.

(**) In the overlay image, black pixels (0 valued) are considered as transparent. If a C24 image is used as overlay, all pixels (but the black ones) will be copied to the destination image. If a BW8 image is used as overlay, all non-black pixels will be converted to the color defined by the OverlayColor parameter before copy to the destination image. The destination image is always a C24 image. If no source image is given (only overlay and destination), the destination image is considered as the source image.
