Oh, that won't work. How about this:

s = Size(image, /Dimensions)
nelem = N_Elements(image)
image4 = [[[image4]],[[image4]],[[image4]]]

image4[mask1] = 255B
image4[mask1 + nelem] = 0B
image4[mask1 + (nelem*2)] = 0B

image4[mask3] = 0B
image4[mask3 + nelem] = 255B
image4[mask3 + (nelem*2)] = 0B

image4[mask2] = 0B
image4[mask2 + nelem] = 255B
image4[mask2 + (nelem*2)] = 255B
TV, image4, True=3

Cheers,

David
