<br>Hi Sutrisno,<br><br>What do you want to save in that .vtk file ?<br><br>1) A Surface ?<br>2) An image ?<br><br><br>If you want to save a surface, then you<br>must first extract an itkMesh out of the image.<br><br><br>
If you want to save an image, then you <br>can simply use itkImageFileWriter <br>You just need to provide a filename with <br>the extension ".vtk".<br><br><br> Regards,<br><br><br> Luis<br><br><br>

<br>Hi Sutrisno,<br><br>This is an understandable confusion.<br><br>The .vtk extension of the legacy VTK file format <br>is used for both files that store images and files<br>that store polydata.<br><br>When you use the .vtk extension for the output<br>
filename of any of the ITK image processing<br>examples, that resulting .vtk file will contain an <br>image, not a polydata.<br><br>That means that if you want to read it back with<br>VTK classes, you should use the vtkImageReader,<br>
and not the vtkPolyDataReader.<br><br>In fact, you may want to use the vtkImageReader2:<br><a rel="nofollow" href="http://www.vtk.org/doc/nightly/html/classvtkImageReader2.html" target="_blank">http://www.vtk.org/doc/nightly/html/classvtkImageReader2.html</a><br>
