    00015 // .NAME vtkGDCMImageWriter - write DICOM files
    00016 // .SECTION Description
    00017 // vtkGDCMImageWriter is a sink object that write DICOM files
    00018 // this writer is single threaded (see vtkGDCMThreadedImageReader2 for multi-thread)
    00019 //
    00020 // .SECTION Warning: vtkLookupTable from the vtkImageData object taken into account
    00021 // only if ImageFormat is set to VTK_LOOKUP_TABLE
    00022 //
    00023 // .SECTION NOTE We are not using the usual API SetFilePrefix / SetFilePattern,
    00024 // but instead a list of filenames: see SetFileNames and class gdcm::FilenameGenerator
    00025 //
    00026 // .SECTION Warning
    00027 // You need to specify the correct ImageFormat (taken from the reader)
    00028 // You need to explicitely specify the DirectionCosines (taken from the reader)
    00029 // Since VTK 5.4 vtkMedicalImageProperties has its own DirectionCosine (no 's')
    00030 // user need to make sure the vtkMatrix4x4 is compatible with the 6-vector DirectionCosine.
    00031 //
    00032 // .SECTION NOTE Shift/Scale are global to all DICOM frames (=files) written
    00033 // as 2D slice, therefore the shift/scale operation might not be optimized for
    00034 // all slices. This is not recommended for image with a large dynamic range.
