StampHeight Property

Summary

Gets and sets the height for the stamp image.

Syntax

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:

CodecsWebpSaveOptions.SaveWithStamp = true
CodecsWebpSaveOptions.StampWidth > 0
StampHeight > 0
CodecsWebpSaveOptions.StampBitsPerPixel = 24

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.
