Hi,
I write the following code to use fltkVTKImageViewer
(InsightApplications/Auxiliary/vtkFltk)to show image:
#include "itkImage.h"
#include "itkDICOMImageIO2.h"
#include "itkImageFileReader.h"
#include "itkDICOMImageIO2Factory.h"
#include "fltkVTKImageViewer.h"
#include <config.h>
#include <FL/Fl.H>
int main(int argc, char **argv)
{
typedef float InputPixelType;
const unsigned int Dimension = 2;
typedef itk::Image< InputPixelType, Dimension > InputImageType;
itk::ObjectFactoryBase::RegisterFactory(itk::DICOMImageIO2Factory::New()
);
itk::DICOMImageIO2::Pointer DICOMImage =
itk::DICOMImageIO2::New();
itk::ImageFileReader<InputImageType>::Pointer fileReader =
itk::ImageFileReader<InputImageType>::New();
fileReader->SetImageIO(DICOMImage);
fileReader->SetFileName("f:\\test\\t1.dcm");
fileReader->UpdateLargestPossibleRegion();
typedef fltk::VTKImageViewer<InputImageType::PixelType>
ImageViewer;
ImageViewer::Pointer viewer = ImageViewer::New();
viewer->SetImage(fileReader->GetOutput());
viewer->Show();
Fl::run();
return 0;
}
it showed such mistake:

Error executing cl.exe.
It made me confused. In class fltkVTKImageViewer, it defines the member
of SetImage() and Show(). Why it found them in its parent class?
Thanks a lot !!
