Syntax
C#
Objective-C
C++/CLI
Java
Python
public int StampBitsPerPixel { get; set; } 
@property (nonatomic, assign) NSUInteger stampBitsPerPixel; 
public int getStampBitsPerPixel() 
public void setStampBitsPerPixel(int value) 
public: 
property int StampBitsPerPixel { 
   int get(); 
   void set (    int ); 
} 
StampBitsPerPixel # get and set (CodecsWebpSaveOptions) 

Property Value

The default value is 24.

The bit depth for the stamp image. Currently, the only value supported is 24.

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.
