Syntax
C#
Objective-C
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 ); 
} 
StampHeight # get and set (CodecsWebpSaveOptions) 

Property Value

The default value is 0

The height for the stamp image.

Remarks

The stamp is saved only if all the following are true:

If any of the above conditions are not met, the stamp is not saved.

The stamp size might be adjusted if CodecsSaveOptions.AdjustStampSize is set.
