public class ShearCommand : RasterCommand, IRasterCommand

'Declaration
 
Public Class ShearCommand 
   Inherits RasterCommand
   Implements IRasterCommand

'Usage
 
Dim instance As ShearCommand

public sealed class ShearCommand : IRasterCommand

function Leadtools.ImageProcessing.ShearCommand()

public ref class ShearCommand : public RasterCommand, IRasterCommand

You specify an angle of slant, horizontal or vertical shear, and the fill color for the created space. The following is a horizontal example:

Horizontal Shear

The angle is expressed in hundredths of degrees, with a limit of 4500 (45 degrees).
