Summary

Amount by which the method rotates the image.

Syntax

Java

Objective-C

WinRT C#

C++

public int Angle {get;}

Public ReadOnly Property Angle As Integer

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.

Example

Run the DeskewCommand on an image and straightens it.
