Hi Caleb,
The code is here, very simple:
/*****************************************/
#include "itkImage.h"
#include "itkImageFileReader.h"
#include "itkImageToVTKImageFilter.h"
#include "vtkImageViewer.h"
#include "vtkRenderWindowInteractor.h"
int main(int argc, char **argv){
typedef itk::Image<unsigned short, 2> ImageType;
typedef itk::ImageFileReader<ImageType> ReaderType;
typedef itk::ImageToVTKImageFilter<ImageType> FilterType;
ReaderType::Pointer reader = ReaderType::New();
FilterType::Pointer connector = FilterType::New();
reader->SetFileName(argv[1]);
connector->SetInput(reader->GetOutput());
vtkImageViewer *viewer = vtkImageViewer::New();
vtkRenderWindowInteractor *renderWindowInteractor =
vtkRenderWindowInteractor::New();
viewer->SetupInteractor(renderWindowInteractor);
viewer->SetInput(connector->GetOutput());
viewer->Render();
viewer->SetColorWindow(2000);
viewer->SetColorLevel(1000);
renderWindowInteractor->Start();
return 0;
}
/**************************************************/
Best,
Cheng
