Normalise to MAX

Clicking the “Normalise to MAX” button normmax normalises the image so that the maximum of the image is 100 and the minimum is zero using the formula:

\[NZ = \cfrac {(Z - min)*100} {max - min}\]

Where max and min are the image maximum and minimum respectively. Z is the current pixel value and NZ is the new pixel value. Clicking the button again will remove the normalisation.
