Angle Property

Summary
Gets or sets the rotation angle
Syntax
C#
Objective-C
C++/CLI
Java
Python
public int Angle { get; set; } 
@property (nonatomic, assign) NSInteger angle; 
public int getAngle(); 
public void setAngle( 
   int intValue 
); 
public: 
property int Angle { 
   int get(); 
   void set (    int ); 
} 
Angle # get and set (HighQualityRotateCommand) 

Property Value

Hundredths of degrees to rotate (+/-). This can be a number from 1 to 36,000. A positive value will rotate the image in a clockwise rotation, while a negative value will rotate the image in a counter-clockwise rotation.
