Angle Property

Leadtools.ImageProcessing.Core Namespace > DeskewCommand Class : Angle Property



Amount by which the method rotates the image. Supported in Silverlight, Windows Phone 7

Syntax

Visual Basic (Declaration) 
Public ReadOnly Property Angle As Integer
Visual Basic (Usage)Copy Code
Dim instance As DeskewCommand
Dim value As Integer
 
value = instance.Angle
C# 
public int Angle {get;}
C++/CLI 
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.
