BinaryFilterCommand Constructor(bool,int[])

Summary

Initializes a new BinaryFilterCommand class object with the specified parameters.

Syntax

Objective-C

C++/CLI

Java

Python

public BinaryFilterCommand( 
   bool maximum, 
   int[] matrix 
)

- (instancetype)initWithMaximum:(BOOL)maximum matrix:(nullable NSArray<NSNumber *> *)matrix NS_DESIGNATED_INITIALIZER;

public BinaryFilterCommand( 
   boolean maximum, 
   int[] matrix 
);

public: 
BinaryFilterCommand(  
   bool maximum, 
   array<int>^ matrix 
)

__init__(self,maximum,matrix) # Overloaded constructor

Parameters

maximum
Value that represents the maximum value.

matrix
Array of filter coefficients.

Remarks

Set maximum to true to erode black objects and false to dilate black objects. The dimension value is the size of the rows and columns of the matrix.

Example

Runs the BinaryFilterCommand on an image to dilate black objects.
