The application probably works from a given image, to know what
shape of image you need, and to copy other properties. If the
given image stores integer data, perhaps the synthesised image
also does. And in integers the cosine function can take only
the values 1, 0 or -1. Just a wild, guess, what the data type
in the given image is.
