EdgeCoefficient Property

Summary

Gets or sets the edge enhancement coefficient.

Syntax

Objective-C

C++/CLI

Java

Python

public int EdgeCoefficient { get; set; }

@property (nonatomic, assign) NSUInteger edgeCoefficient;

public int getEdgeCoefficient(); 
public void setEdgeCoefficient( 
   int intValue 
);

public: 
property int EdgeCoefficient { 
   int get(); 
   void set (    int ); 
}

EdgeCoefficient # get and set (MultiscaleEnhancementCommand)

Property Value

The edge enhancement coefficient. This value will be internally divided by 100. Pass -1 to use the default values (which is 170 interpreted as 1.7). This option will be used only if EdgeEnhancment is set in the Flags property. Any value (>= 0) is valid. A value of 100 will be interpreted as 1.0 and will keep the image's edges un-enhanced. Larger values will produce more visible edges. Smaller values will produce less visible edges. Practically, the enhancement levels out at 200000 (interpreted as 2000.0) - values bigger than that will not enhance the image's edges any more.
