+
and

+
+ to allow user to choose the 'Private Dictionary' he wants to work with.

+
+ -
+ PrintFile has now a new command line argument manager option :
+ dict=fullPathNamePrivateDictionaryFile
+ to allow user to see with no extra coding what differences
+ makes the use or not of a private Dicom Dictionary.
+ e.g. : use it as follow
+ PrintFile filein=myGEdicomFile.dcm
+ dict=/user/userName/gdcm/Dicts/GEMS-Advance.dic

+ void Document::AddForceLoadElement(uint16_t group, uint16_t elem);

+ MAX_SIZE_LOAD_ELEMENT_VALUE.
+

+ Many users expect from vtkGdcmReader it 'orders' the images
+ (that's the job of gdcm::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();
+ // 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( ...
+ sh->SetDirectory(directoryWithImages);
+
+ // if user *knows* how to order his files
+ sh->SetUserLessThanFunction(userSuppliedComparisonFunction);
+ // or/and
+ // if user wants to sort reverse order
+ sh->SetSortOrderToReverse();
+
+ // here, we suppose only the first 'Single SerieUID' Fileset is of interest
+ // Just iterate using sh->NextSingleSerieUIDFileSet()
+ // if you want to get all of them
+ gdcm::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, or not same 'pixel type' -> stop
+
+ sh->OrderFileList(l); // sort the list
+
+ vtkGdcmReader *reader = vtkGdcmReader::New();
+ // if user wants to modify pixel order (Mirror, TopDown, ...)
+ // 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 'Single SerieUID' Fileset as produced by gdcm::SerieHelper
+ reader->SetCoherentFileList(l);
+ reader->Update();
+
+ You can see a full example in vtk/vtkgdcmSerieViewer.cxx
+ e.g.
+
+ vtkgdcmSerieViewer dirname=Dentist mirror
+ vtkgdcmSerieViewer dirname=Dentist reverse
+ vtkgdcmSerieViewer dirname=Dentist reverse topdown
+
+
+
+ - vtkGdcmReader::SetUserFunction (userSuppliedFunction)
+ with :
+ void userSuppliedFunction(uint8_t *imageData, File *f);
+ allows user to reorganize the pixels of each image just after reading
+ it (to mirror, or topdown the image, for instance)
+ Note : uint8_t * doesn't mean it works only on 8 Bits images.
+
It's for prototyping. Feel free to cast it.
+
+ -
+ SerieHelper::SetUserLessThanFunction(userSuppliedComparisonFunction)
+
with :
+ bool userSuppliedComparisonFunction(File *, File *);
+ allows user -when he knows more about his files than gdcm does-
+ to give his own comparison function.
+ - SerieHelper::SetSortOrderToReverse allows user to ask
+ to sort the Files reverse order.
+
- SerieHelper::AddRestriction has now a new constructor
+ AddRestriction(group, element, value, operator);
+ allows user to exclude some files from the sorting, according to
+ any comparison operator
+ (GDCM_EQUAL, GDCM_DIFFERENT,
+ GDCM_GREATER, GDCM_GREATEROREQUAL,
+ GDCM_LESS, GDCM_LESSOREQUAL), not only on the
+ equality.
+
+ - AnonymizeNoLoad used with dirin=inputDirectoryName
+ anonymizes all the files within the given Directory.
+
+ User may also choose extra elements he wants to rub out:
+ rubout=listOfElementsToRubOut
+ with listOfElementsToRubOut : group1-elem1,group2-elem2,
+ ... (in hexa, no space within the list )
+
+ - gdcm::SerieHelper() has a new method
+ void AddGdcmFile(File *header), that allows aware user to
+ create a 'FileList' (actually a
+ std::vector< File* > ).
+ The FileList created this way will be the
+ 'first one' in the gdcm::FileHelper() (retrieve it with
+ FileList *GetFirstCoherentFileList() ).
+ It may be sorted using OrderFileList.
+ No 'coherence check' will be performed on this FileList
+ before sorting.
+ It may be passed to a vtkGdcmReader
+ (to avoid parsing twice the files)
+
+ - vtkGdcmReader can now get the result of
+ gdcm::SerieHelper (to avoid parsing twice the files)
+ Proceed as follow :
+
+ gdcmSerieHelper *sh = new gdcmSerieHelper();
+ sh->SetDirectory(myImageDirectory, true);
+ gdcmFileList *l = s->GetFirstCoherentFileList();
+ s->OrderFileList(l);
+
+ vtkGdcmReader *gr = new vtkGdcmReader();
+ gr->SetCoherentFileList(l);
+ gr->Update();
+
+ This works with a directory that contains only one 'Serie'
+ (same Serie UID for all the images).
+ If it contains more than one Serie, you'll have to loop
+ on the Series, using GetNextCoherentFileList();
+ It will be up to the user to delete the gdcm::File.
+
+ See vtkgdcmSerieViewer for an example.
