Summary
Wraps the image along its radius on a 3D surface shaped by Curve. This command is available in the Imaging and above toolkits.
Syntax
C#
C++/CLI
Python
public class FreeRadialBendCommand : RasterCommand 
public ref class FreeRadialBendCommand : public RasterCommand   
class FreeRadialBendCommand(RasterCommand): 
Remarks
  • If the image has a region, the effect will be applied on the region only.
  • For an example, the following figure shows an image before the effect is applied.

    freeradbend-before.jpg

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

    freeradbend-after.jpg
  • 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 FreeRadialBendCommand on an image.

C#
using Leadtools; 
using Leadtools.Codecs; 
using Leadtools.ImageProcessing.SpecialEffects; 
using Leadtools.ImageProcessing.Effects; 
 
 
public void FreeRadialBendCommandExample() 
{ 
   // Load an image 
   RasterCodecs codecs = new RasterCodecs(); 
   codecs.ThrowExceptionsOnInvalidImages = true; 
 
   RasterImage image = codecs.Load(Path.Combine(LEAD_VARS.ImagesDir, "sample5.cmp")); 
 
   // Prepare the command 
   FreeRadialBendCommand command = new FreeRadialBendCommand(); 
   LeadPoint[] UserPoint = new LeadPoint[4]; 
   LeadPoint CenterPoint = new LeadPoint(image.Width / 2, image.Height / 2); 
   int[] Curve = new int[13]; 
 
   //Apply the filter

   UserPoint[0].Y = 0; 
   UserPoint[1].X = 3; 
   UserPoint[1].Y = 10; 
   UserPoint[2].X = 9; 
   UserPoint[2].Y = -10;

   UserPoint[3].Y = 0; 
 
   EffectsUtilities.GetCurvePoints(Curve, UserPoint, CurvePointsType.Linear); 
   for (int i = 0; i < Curve.Length; i++) 
      Curve[i] /= 50; 
   command.Flags = FreeRadialBendCommandFlags.Color | FreeRadialBendCommandFlags.Rotate; 
   command.CenterPoint = CenterPoint; 
   command.Scale = 200; 
   command.FillColor = new RasterColor(255, 0, 0); 
   command.Curve = Curve;
