Angle Property
See Also  Example
Leadtools.ImageProcessing.Core Namespace > DeskewCheckCommand Class : Angle Property



Support for this function will be discontinued in the next major release of LEADTOOLS. Use DeskewCommand instead. Amount by which the command rotates the image.

Syntax

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

Return Value

Amount by which the command 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. The default value is 0.

Example

Run the DeskewCommand on an image and straightens it.
