public ShiftDataCommand( 
   int sourceLowBit,
   int sourceHighBit,
   int destinationLowBit,
   int destinationBitsPerPixel
)

'Declaration
 
Public Function New( _
   ByVal sourceLowBit As Integer, _
   ByVal sourceHighBit As Integer, _
   ByVal destinationLowBit As Integer, _
   ByVal destinationBitsPerPixel As Integer _
)

'Usage
 
Dim sourceLowBit As Integer
Dim sourceHighBit As Integer
Dim destinationLowBit As Integer
Dim destinationBitsPerPixel As Integer
 
Dim instance As New ShiftDataCommand(sourceLowBit, sourceHighBit, destinationLowBit, destinationBitsPerPixel)

public ShiftDataCommand( 
   int sourceLowBit,
   int sourceHighBit,
   int destinationLowBit,
   int destinationBitsPerPixel
)

function ShiftDataCommand( 
   sourceLowBit ,
   sourceHighBit ,
   destinationLowBit ,
   destinationBitsPerPixel 
)

public:
ShiftDataCommand( 
   int sourceLowBit,
   int sourceHighBit,
   int destinationLowBit,
   int destinationBitsPerPixel
)

Parameters

sourceLowBit: Position of the start bit that will construct the mask. The position is a zero-based number. This parameter accepts only positive values.
sourceHighBit: Position of the end bit. This is inclusive (it is part of the mask). The value should not be less than sourceLowBit. You can also pass -1, which is interpreted as "highest bit" (SourceImage->BitsPerPixel - 1). This parameter accepts only positive values.
destinationLowBit: The bit position where the selected mask will be copied into the destination image. This parameter accepts only positive values.
destinationBitsPerPixel: Bits per pixel for the destination image. The allowed values are 8, 12, or 16.
