public ZeroToNegativeCommand( 
   int shiftAmount,
   int minimumInput,
   int maximumInput,
   int minimumOutput,
   int maximumOutput
)

'Declaration
 
Public Function New( _
   ByVal shiftAmount As Integer, _
   ByVal minimumInput As Integer, _
   ByVal maximumInput As Integer, _
   ByVal minimumOutput As Integer, _
   ByVal maximumOutput As Integer _

'Usage
 
Dim shiftAmount As Integer
Dim minimumInput As Integer
Dim maximumInput As Integer
Dim minimumOutput As Integer
Dim maximumOutput As Integer
 
Dim instance As New ZeroToNegativeCommand(shiftAmount, minimumInput, maximumInput, minimumOutput, maximumOutput)

public ZeroToNegativeCommand( 
   int shiftAmount,
   int minimumInput,
   int maximumInput,
   int minimumOutput,
   int maximumOutput
)

function ZeroToNegativeCommand( 
   shiftAmount ,
   minimumInput ,
   maximumInput ,
   minimumOutput ,

)

public:
ZeroToNegativeCommand( 
   int shiftAmount,
   int minimumInput,
   int maximumInput,
   int minimumOutput,
   int maximumOutput
)

Parameters

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.
