public class TunnelCommand : Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

'Declaration
 
Public Class TunnelCommand 
   Inherits Leadtools.ImageProcessing.RasterCommand
   Implements Leadtools.ImageProcessing.IRasterCommand

'Usage
 
Dim instance As TunnelCommand

public sealed class TunnelCommand : Leadtools.ImageProcessing.IRasterCommand

function Leadtools.ImageProcessing.SpecialEffects.TunnelCommand()

public ref class TunnelCommand : public Leadtools.ImageProcessing.RasterCommand, Leadtools.ImageProcessing.IRasterCommand

This command shows the effect of placing images on tunnels along the Z-axis and bending them toward a specific point. These images may be placed above, below, to the left or to the right of the Z-axis. An external light source of the specified color and brightness may be shined on the images. The brightness may vary along the z-axis according to the BrightLength value.
Changing the camera center point, the rotation angle and the viewing screen Z-offset will simulate moving along the axis.
If the image has a region, the effect will be applied on the region dimensions only.
For an example, see the following figure:

The following figure shows the same image, after the effect has been applied:

To obtain this effect, the following settings were used with the command:
1. CenterPoint = new Leadtools.LeadPoint(320, 256)
2. ZValue = 0
3. Distance = 200
4. Radius = 200
5. Repeat = -1
6. RotationOffset = 75
7. Stretch = 25
8. StartBright = 0
9. EndBright = 100
10. BrightLength = 45
11. BrightColor = new Leadtools.RasterColor(255, 255, 255)
12. FillColor = new Leadtools.RasterColor(255, 255, 255)
13. Flags = TunnelCommandFlags.WidthAxis | TunnelCommandFlags.Color
This command supports 12- and 16-bit grayscale and 48- and 64-bit color images. Support for 12- and 16-bit grayscale and 48- and 64-bit color images is available only in the Document/Medical toolkits.
This command does not support signed data images.
This command does not support 32-bit grayscale images.
