[vtkusers] easy example

[Dominik Paul]

Helle there

does somebody have any very easy examples for dreactin an ImagaData and
showing it?

My example isnt running, that means the window shows nothing, just black

Dom

Example:

#include <vtkImageData.h>
#include <vtkImageViewer.h>
#include <iostream.h>
#include <vtktiffreader.h>
#include <vtkimagereader.h>




main()
{


 //vtkTiffReader* theReader = vtkTiffReader::New();
 vtkImageReader* theReader = vtkImageReader::New();
 theReader ->SetFileName("Testbild");

 void  SetFileName (const char *)
 vtkImageData* volume = vtkImageData::New();



  volume -> Print(cout);
  volume -> UpdateInformation();
  volume -> Update();
  volume -> Print(cout);

     vtkImageViewer* theViewer = vtkImageViewer::New();
  theViewer -> SetInput(volume);
  theViewer -> SetZSlice(2);
  theViewer -> Render();

  while (1)
  {
  theViewer -> SetInput(volume);
  theViewer -> SetZSlice(2);
  theViewer -> Render();

  int hallo;
  cin >> hallo;
  if (hallo == 1) break;
  }
}
