public class ShearCommand : RasterCommand, IRasterCommand

'Declaration

Public Class ShearCommand 
   Inherits RasterCommand
   Implements IRasterCommand

'Usage

Dim instance As ShearCommand

public sealed class ShearCommand : IRasterCommand

@interface LTShearCommand : LTRasterCommand

public class ShearCommand extends RasterCommand

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).

This command supports signed/unsigned data images.

For more information, refer to Introduction to Image Processing With LEADTOOLS.

This example shears the image 15 degrees vertically, filling extra space with blue.
