public int Angle {get;}

'Declaration

Public ReadOnly Property Angle As Integer

'Usage

Dim instance As DeskewCommand
Dim value As Integer
 
value = instance.Angle

public int Angle {get;}

@property (nonatomic, assign, readonly) NSInteger angle

public int getAngle()

 get_Angle();

public:
property int Angle {
   int get();
}

Property Value

Amount by which the method rotates the image. The amount of rotation is expressed in hundredths of degrees. For example, 500 means 5 degrees clockwise. Valid values range from -2000 through 2000.

Run the DeskewCommand on an image and straightens it.
