The Blend options are similar to the commands in the Processing menu. They use the RGB values of the cutout and those of the result image. Select a blend option from the Blend Mode box.
(a) Blend Mode box
BlendPastes the cutout onto the result image.
AddAdds the RGB values of the corresponding pixels in the cutout and the result image. Values greater than 255 are clipped.
SubtractSubtracts the RGB values of pixels in the image from those of the cutout. Values less than 0 are clipped.
BlackPastes a black object in the shape of the cutout on the result image.
WhitePastes a white object in the shape of the cutout on the result image.
ColourPastes a coloured object in the shape of the cutout on the result image. The current colour is used for the object.
NAdd MinCompares the brightness values of corresponding pixels in the cutout and the result image, and uses the pixel with the smaller value in the tacked down cutout.
NAdd MaxCompares the brightness values of corresponding pixels in the cutout and the result image, and uses the pixel with the greater value in the tacked down cutout.
MultiplyMultiplies the RGB values of corresponding pixels in the cutout and the result image. The value is normalized by dividing the result by 255.
