shiftAmount
Value that is used to shift the image data to the negative side.
minimumInput
The image minimum value. This value can be optained MinMaxValuesCommand
maximumInput
The image maximum value. This value can be optained 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 axceed this value.
Initializes a new ZeroToNegativeCommand class object with explicit parameters.
