With the MaskCopyTool two images can be copied into each other with the help of a mask. Inside the mask (white pixels) the InputImage is used, outside the mask (black pixels) the so-called PasspartoutImage.


Instead of the PasspartoutImage, the result image can also be filled with a gray value constant (Background Constant). The Use Passpartout Image setting determines whether the PasspartoutImage or the gray value constant is to be used.
