// .NAME vtkGDCMImageWriter - write DICOM files
// .SECTION Description
// vtkGDCMImageWriter is a sink object that write DICOM files
// this writer is single threaded (see vtkGDCMThreadedImageReader2 for multi-thread)
//
// .SECTION Warning: vtkLookupTable from the vtkImageData object taken into account
// only if ImageFormat is set to VTK_LOOKUP_TABLE
//
// .SECTION NOTE We are not using the usual API SetFilePrefix / SetFilePattern,
// but instead a list of filenames: see SetFileNames and class gdcm::FilenameGenerator
//
// .SECTION Warning
// You need to specify the correct ImageFormat (taken from the reader)
// You need to explicitly specify the DirectionCosines (taken from the reader)
// Since VTK 5.4 vtkMedicalImageProperties has its own DirectionCosine (no 's')
// user need to make sure the vtkMatrix4x4 is compatible with the 6-vector DirectionCosine.
//
// .SECTION NOTE Shift/Scale are global to all DICOM frames (=files) written
// as 2D slice, therefore the shift/scale operation might not be optimized for
// all slices. This is not recommended for image with a large dynamic range.
//
// .SECTION See Also
