-// This example illustrates how the vtkGdcmReader vtk class can be
-// used in order to:
-// * produce a simple (vtk based) Dicom image STACK VIEWER.
-// * dump the stack considered as a volume in a vtkStructuredPoints
-// vtk file: the vtk gdcm wrappers can be seen as a simple way to convert
-// a stack of Dicom images into a native vtk volume.
-//
+// This example illustrates how the vtkGdcmReader vtk class can
+// use the result of gdcm::SerieHelper constructor and check
+// the various Setters :
+// SerieHelper::SetOrderToReverse,
+// SerieHelper::SetUserLessThanFunction
+// SerieHelper::SetLoadMode
+// vtkGdcmReader::SetUserFunction
+// vtkGdcmReader::SetCoherentFileList
// Usage:
// * the Directory name that contains the Dicom images constituting the stack
-// should be given as command line argument,
+// should be given as command line argument (keyword : dirname=),
// * you can navigate through the stack by hitting any character key,
// * the produced vtk file is named "foo.vtk" (in the invocation directory).
