SpatialFilterCommand Constructor(int,int,int[])

Summary

Initializes a new SpatialFilterCommand class object with explicit parameters.

Syntax
C#
VB
Objective-C
C++
Java
public SpatialFilterCommand( 
   int divisor, 
   int bias, 
   int[] matrix 
) 
Public Function New( _ 
   ByVal divisor As Integer, _ 
   ByVal bias As Integer, _ 
   ByVal matrix() As Integer _ 
) 
- (instancetype)initWithDivisor:(NSInteger)divisor 
                           bias:(NSInteger)bias 
                         matrix:(nullable const int *)matrix 
                   matrixLength:(NSUInteger)matrixLength 
public SpatialFilterCommand( 
   int divisor,  
   int bias,  
   int[] matrix 
) 
public: 
SpatialFilterCommand(  
   int divisor, 
   int bias, 
   array<int>^ matrix 
) 

Parameters

divisor
Number used to divide the sum of weighted values.

bias
Number added to the weighted average.

matrix
The array of weighting factors. The factors apply to pixels in the neighborhood read left to right and top to bottom, as shown below:
