[vtkusers] vtkDICOMImageReader broken in vtk 5.0 and up?

[Ben Fulton]

The bug appears to be in vtkDICOMImageReader::ExecuteData.  Apparently the
buffer returned by data->GetScalarPointer() is not large enough to hold the
copied image data when it is flipped, and the data in imgData is being
overwritten.  Could someone explain how this buffer size is determined?

Did anything come of this?  I'm trying to figure out how to use
vtkDICOMImageReader now, and getting crashes as well.  I based my code on an
old email from this list - maybe it's out of date now?


int main()
{
   vtkDICOMImageReader *reader = vtkDICOMImageReader::New();
   vtkImageViewer2     *viewer = vtkImageViewer2::New();

   viewer->SetInput(reader->GetOutput());
   reader->SetDirectoryName("C:\\VTK 5.0\\src\\sample\\study1");
   reader->Update();

   int VolData_Images = viewer->GetSliceMax ();

   for (int i=0;i<=VolData_Images;i++)
   {
     viewer->SetSlice(i);
     //for vtkImageViewer2 before r1.19
     viewer->GetRenderer()->ResetCameraClippingRange();
     viewer->Render();
   }
   reader->Delete();
   viewer->Delete();

   return 0;
}

Can you send me a sample data to reproduce the problem ?

Thanks
