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
C++
public class PlaneBendCommand : RasterCommand 
  
Public Class PlaneBendCommand  
   Inherits RasterCommand 
public ref class PlaneBendCommand : public RasterCommand   

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:

    planebend-before.jpg

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

    planebend-after.jpg

    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.

C#
VB
using Leadtools; 
using Leadtools.Codecs;

{ 
   // Load an image

   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   PlaneBendCommand command = new PlaneBendCommand(); 
   command.CenterPoint = new LeadPoint(image.Width / 2, image.Height / 2); 
   command.ZValue = 0; 
   command.Distance = image.Height; 
   command.PlaneOffset = image.Width / 2; 
   command.Repeat = -1; 
   command.PyramidAngle = 0; 
   command.Stretch = 100; 
   command.BendFactor = 400;
