public DynamicBinaryCommand( 
   int dimension,
   int localContrast
)

'Declaration
 
Public Function New( _
   ByVal dimension As Integer, _
   ByVal localContrast As Integer _
)

'Usage
 
Dim dimension As Integer
Dim localContrast As Integer
 
Dim instance As New DynamicBinaryCommand(dimension, localContrast)

public DynamicBinaryCommand( 
   int dimension,
   int localContrast
)

function DynamicBinaryCommand( 
   dimension ,
   localContrast 
)

public:
DynamicBinaryCommand( 
   int dimension,
   int localContrast
)

Parameters

dimension: Dimensions of the neighborhood used when evaluating each pixel (Dimension x Dimension), in pixels. This should be at least 1.
localContrast: Local contrast threshold. If the contrast of the area surrounding the pixel is less than the LocalContrast property, the pixel is converted to black or white using a global pre-calculated threshold. If the contrast of the area surrounding the pixel is higher than the LocalContrast property, the local threshold value is calculated and used. The range for the LocalContrast property is 0 to 255 for 8-bit, 0 to 4095 for 12-bit and 0 to 65535 for 16-bit.
