| The histogram window is responsible for assigning transformations from image original values (in any range) to palette range [0, 255]. The histogram curve will adjust any value smaller than the "From:" limit to 0, and any value greater than the "To:" limit to 255. Any other values will be mapped using the histogram curve to the "Y" coordinate on the color palette on the left. | The histogram window is responsible for assigning transformations from image original values (in any range) to palette range [0, 255].
