MinimumOutput Property

Summary

Gets or sets the minimum allowed value.

Syntax

Objective-C

C++/CLI

Java

Python

public int MinimumOutput { get; set; }

@property (nonatomic, assign) NSInteger minimumOutput;

public int getMinimumOutput(); 
public void setMinimumOutput( 
   int intValue 
);

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

MinimumOutput # get and set (ZeroToNegativeCommand)

Property Value

The minimum allowed value, which means that the image data values after applying the command will not be less than this value.
