//===> Many users expect from vtkGdcmReader it 'orders' the images
-// (that's the job of gdcm::SerieHelper ...)
+// (that's the job of GDCM_NAME_SPACE::SerieHelper ...)
// When user *knows* the files with same Serie UID
// have same sizes, same 'pixel' type, same color convention, ...
// the right way to proceed is as follow :
//
-// gdcm::SerieHelper *sh= new gdcm::SerieHelper();
+// GDCM_NAME_SPACE::SerieHelper *sh= new GDCM_NAME_SPACE::SerieHelper();
// // if user wants *not* to load some parts of the file headers
// sh->SetLoadMode(loadMode);
+//
// // if user wants *not* to load some files
// sh->AddRestriction(group, element, value, operator);
// sh->AddRestriction( ...
//
// // if user wants to sort reverse order
// sh->SetSortOrderToReverse();
-// // here, we suppose only the first Coherent File List is of interest
-// gdcm::FileList *l = sh->GetFirstCoherentFileList();
+//
+// // here, we suppose only the first 'Serie' is of interest
+// // it's up to the user to decide !
+// GDCM_NAME_SPACE::FileList *l = sh->GetFirstSingleSerieUIDFileSet();
+//
// // if user is doesn't trust too much the files with same Serie UID
// if ( !sh->IsCoherent(l) )
// return; // not same sizes, same 'pixel' type -> stop
+//
+// // WARNING : all that follows works only with 'bona fide' Series
+// // (In some Series; there are more than one 'orientation'
+// // Don't expected to build a 'volume' with that!
+// //
+// // -> use sh->SplitOnOrientation(l)
+// // - or sh->SplitOnPosition(l), or SplitOnTagValue(l, gr, el) -
+// // depending on what you want to do
+// // and iterate on the various 'X Coherent File Sets'
+//
+// // if user *knows* he has to drop the 'duplicates' images
+// // (same Position)
+// sh->SetDropDuplicatePositions(true);
+//
+// // Sorting the list is mandatory
+// // a side effect is to compute ZSpacing for the file set
// sh->OrderFileList(l); // sort the list
//
// vtkGdcmReader *reader = vtkGdcmReader::New();
+//
// // if user wants to modify pixel order (Mirror, TopDown, 90°Rotate, ...)
// // he has to supply the function that does the job
// // (a *very* simple example is given in vtkgdcmSerieViewer.cxx)
// reader->SetUserFunction (userSuppliedFunction);
-// // to pass a 'Coherent File List' as produced by gdcm::SerieHelper
