Leadtools.ImageProcessing.SpecialEffects Namespace : PlaneBendCommand Class



Places the image on parallel planes along the Z-axis, and bends the planes toward the center point. This command is available in the Raster Pro and above toolkits.

Syntax

Visual Basic (Declaration)  
Public Class PlaneBendCommand 
   Inherits RasterCommand
   Implements IRasterCommand 
Visual Basic (Usage) Copy Code
Dim instance As PlaneBendCommand
C#  
public class PlaneBendCommand : RasterCommand, IRasterCommand 
C++/CLI  
public ref class PlaneBendCommand : public RasterCommand, IRasterCommand 

Example

Run the PlaneBendCommand on an image.

Remarks

  • This command shows the effect of placing images on planes 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 bright length value. The line of images may be bent toward a specific point by setting a bending value.
  • By changing the center point and the viewing screen Z-offset, you can 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 method:
    1. CenterPoint = new Point(640, 256)
    2. ZValue = 0
    3. Distance = 256
    4. PlaneOffset = 256
    5. Repeat = -1
    6. PyramidAngle = 0
    7. Stretch = 100
    8. BendFactor = 500
    9. StartBright = 0
    10. EndBright = 0
    11. BrightLength = 50
    12. BrightColor = new RasterColor(255, 255, 255)
    13. FillColor = new RasterColor(0, 0, 0)
    14. Flags = PlaneCommandFlags.Down | PlaneCommandFlags.Color
    15. This command does not support 32-bit grayscale images.
  • 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.
