[vtkusers] vtkDICOMImageReader and an extrange error,..

[Dongqing Chen]

Hello, Miguel:

  The C code patch has been tested just recently, it reads all the all the 
DICOM Image, and shows slice-by-slice an independent window.

  it works well for me. Hopefully it helps.

//-----------------------------------------------------------------------------------------------------------------------------------------
    vtkDICOMImageReader *reader = vtkDICOMImageReader::New();
    vtkImageViewer *viewer = vtkImageViewer::New();

     reader->SetDirectoryName(dirName);//change to the folder where your 
docom images are saved.

    viewer->SetInput(reader->GetOutput());
    reader->Update();

    double *dicom_range = reader->GetOutput()->GetScalarRange(); //max and 
mim CT number in Hounsfiled

    int num_slices = viewer->GetWholeZMax ();

     for (int i=0;i<=num_slices;i++)
     {

      int dicom_width=reader->GetWidth();
       int dicom_height=reader->GetHeight();
       double *dicom_spacing=reader->GetPixelSpacing();
       const char *dicom_patient_name=reader->GetPatientName();

    printf("-------------------------------------------------\n");
    printf("This Is Slice Number %d out of Total %d\n", i,num_slices);
    printf("Some Basic Info for Slice Number %d \n", i);
    printf("Weight=%d \n", dicom_width);
    printf("Height=%d \n", dicom_height);
    printf("Spatial Resoltion=[%5.3f,%5.3f,%5.3f]\n", 
dicom_spacing[0],dicom_spacing[1],dicom_spacing[2]);
    printf("-------------------------------------------------\n");


       viewer->SetZSlice(i);
       viewer->GetRenderer()->ResetCameraClippingRange();
       viewer->SetColorWindow(400);
       viewer->SetColorLevel(128);

       viewer->Render();
}

     printf("Max and Min Pixel Values for the Whole 
Dataset=[%9.3f,%9.3f]\n", dicom_range[1],dicom_range[0]);

     reader->Delete();
     viewer->Delete();
//----------------------------------------------------------------------------------------------------------------------------------
