Parameters

shiftAmount: Value that is used to shift the image data to the negative side.
minimumInput: The image minimum value. This value can be obtained MinMaxValuesCommand
maximumInput: The image maximum value. This value can be obtained MinMaxValuesCommand
minimumOutput: The minimum allowed value, which means that the image data values after applying the command will not be less than this value.
maximumOutput: The maximum allowed value, which means that the image data values after applying the command will not exceed this value.
