data(texmos2)
plot(as.raster(texmos2))

# the appearance of next one doesn't change because of normalization
x <- normalize(2 * texmos2)
plot(as.raster(x))
title(main = "Doubled pixel value with normalization", font.main = 1)

# the next one is saturated as expected
x <- clipping(2 * texmos2)
plot(as.raster(x))
title(main = "Doubled pixel value with clipping", font.main = 1)
