PlaneBendCommand Class

Summary

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

Syntax

C#
VB
WinRT C#
C++
public class PlaneBendCommand : RasterCommand 
function Leadtools.ImageProcessing.SpecialEffects.PlaneBendCommand() 

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 Leadtools.LeadPoint(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 Leadtools.RasterColor(255, 255, 255)
    13. FillColor = new Leadtools.RasterColor(0, 0, 0)
    14. Flags = PlaneCommandFlags.Down | PlaneCommandFlags.Color
    15. This command does not support 32-bit grayscale images.
  • This command supports 12-bit and 16-bit grayscale and 48-bit and 64-bit color images. Support for 12-bit and 16-bit grayscale and 48-bit and 64-bit color images is available only in the Document/Medical toolkits.

  • This command does not support signed data images.

Example

Run the PlaneBendCommand on an image.

   // Prepare the command 
   PlaneBendCommand command = new PlaneBendCommand();
