[Insight-users] itkVTKtoITKtoVTK modification

[Pieter Vos]

Hi,

Maybe I can help. I think you are forgetting to set up an input/output
object:

  //setup in/output
  itk::PNGImageIO::Pointer io;
  io = itk::PNGImageIO::New();

  //Read image
  itk::ImageFileReader<RGBImageType>::Pointer reader;
  reader = itk::ImageFileReader<RGBImageType>::New();
  reader->SetFileName( filename );
  reader->SetImageIO(io);

Also use the smartpointer in sted of the clean star.
You can look in the map /Insight/Testing/Code/IO
for more examples.
