C++/CLI

Java

Python

public int StampHeight { get; set; }

@property (nonatomic, assign) NSUInteger stampHeight;

public int getStampHeight() 
public void setStampHeight(int value)

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

Property Value

The default value is 0

The height for the stamp image.

Remarks

The stamp size might be adjusted to fit inside the stamp width x height rectangle if CodecsSaveOptions.AdjustStampSize is set.
