+ <LI> New Features
+ <UL>
+ <LI> Add the methods
+ <TT>gdcm::Dict:AddDict(std::string fullPathPrivateDictionaryFileName)</TT>
+ <br>and<br>
+ <TT>gdcm::Dict::RemoveDict(std::string fullPathPrivateDictionaryFileName)</TT>
+ <br>
+ to allow user to choose the 'Private Dictionary' he wants to work with.
+ <br>
+ One can dream about a better API;<br>
+ This one allow right now anybody to see very easyly if the use
+ of a given private dicom dictionary is of any help or not.
+ <br><br>
+ <LI>
+ <TT>PrintFile</TT> has now a new command line argument manager option :<br>
+ <TT>dict=fullPathNamePrivateDictionaryFile</TT><br>
+ to allow user to see with no extra coding what differences
+ makes the use or not of a private Dicom Dictionary.<br>
+ e.g. : use it as follow <br>
+ <TT>PrintFile filein=myGEdicomFile.dcm
+ dict=/user/userName/gdcm/Dicts/GEMS-Advance.dic</TT>
+ <br><br>
+ <LI>
+ (Not a great one ...)
+ Stupid method names : <br><TT>DicomDir::WriteDicomDir()</TT>
+ and <TT>DicomDir::AnonymizeDicomDir()</TT> <br>replaced by : <br>
+ <TT>DicomDir::Write()</TT>
+ and <TT>DicomDir::Anonymize()</TT>
+ <br><br>
+ <LI><TT>
+ void Document::AddForceLoadElement(uint16_t group, uint16_t elem);
+ </TT><br>
+ allows user to tell <TT>gdcm::Document</TT> Loader he wants
+ to force the loading of a given set of <TT>DocEntries</TT>,
+ even if their length exceeds the current
+ <TT>MAX_SIZE_LOAD_ELEMENT_VALUE</TT>.
+ <br><br>
+ <LI>
+ Many users expect from <TT>vtkGdcmReader</TT> it 'orders' the images
+ (that's the job of <TT>gdcm::SerieHelper</TT> ...)<br>
+ When user <b>knows</b> the files with same Serie UID
+ have same sizes, same 'pixel' type, same color convention, ...
+ the right way to proceed is as follow :
+ <pre>
+ 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();
+ </pre>
+ You can see a full example in <TT>vtk/vtkgdcmSerieViewer.cxx</TT><br>
+ e.g.<br>
+
+ <TT>vtkgdcmSerieViewer dirname=Dentist mirror</TT><br>
+ <TT>vtkgdcmSerieViewer dirname=Dentist reverse</TT><br>
+ <TT>vtkgdcmSerieViewer dirname=Dentist reverse topdown</TT><br>
+ </pre>
+ <br>
+
+ <LI> <TT>vtkGdcmReader::SetUserFunction (userSuppliedFunction)</TT><br>
+ with :<br>
+ <TT>void userSuppliedFunction(uint8_t *imageData, File *f);</TT><br>
+ allows user to reorganize the pixels of each image just after reading
+ it (to mirror, or topdown the image, for instance)<br>
+ Note : <TT>uint8_t *</TT> doesn't mean it works only on 8 Bits images.
+ <br> It's for prototyping. Feel free to cast it.
+ <br><br>
+ <LI> <TT>
+ SerieHelper::SetUserLessThanFunction(userSuppliedComparisonFunction)
+ </TT><br> with : <br>
+ <TT>bool userSuppliedComparisonFunction(File *, File *);</TT><br>
+ allows user -when he knows more about his files than gdcm does-
+ to give his own comparison function.
+ <LI> <TT>SerieHelper::SetSortOrderToReverse</TT> allows user to ask
+ to sort the Files reverse order.
+ <LI> <TT>SerieHelper::AddRestriction</TT> has now a new constructor<br>
+ <TT>AddRestriction(group, element, value, operator);</TT><br>
+ allows user to exclude some files from the sorting, according to
+ any comparison operator <br>
+ (<TT>GDCM_EQUAL</TT>, <TT>GDCM_DIFFERENT</TT>,
+ <TT>GDCM_GREATER</TT>, <TT>GDCM_GREATEROREQUAL</TT>,
+ <TT>GDCM_LESS</TT>, <TT>GDCM_LESSOREQUAL</TT>), not only on the
+ equality.
+ <br><br>
+ <LI> <TT>AnonymizeNoLoad</TT> used with <TT>dirin=inputDirectoryName</TT>
+ anonymizes all the files within the given Directory.
+ <br>
+ User may also choose extra elements he wants to rub out: <br>
+ <TT>rubout=listOfElementsToRubOut</TT><br>
+ with <tt>listOfElementsToRubOut : group1-elem1,group2-elem2,
+ ...</TT> (in hexa, no space within the list )
+ <br><br>
+ <LI> <TT>gdcm::SerieHelper()</TT> has a new method
+ <TT>void AddGdcmFile(File *header)</TT>, that allows aware user to
+ create a '<TT>FileList</TT>' (actually a
+ <TT>std::vector< File* > </TT>).<br>
+ The <TT>FileList</TT> created this way will be the
+ 'first one' in the <TT>gdcm::FileHelper()</TT> (retrieve it with
+ <TT>FileList *GetFirstCoherentFileList()</TT> ).<br>
+ It may be sorted using <TT>OrderFileList</TT>.<br>
+ No 'coherence check' will be performed on this <TT>FileList</TT>
+ before sorting.<br>
+ It may be passed to a <TT>vtkGdcmReader</TT>
+ (to avoid parsing twice the files)
+ <br><br>
+ <LI> <TT>vtkGdcmReader</TT> can now get the result of
+ <TT>gdcm::SerieHelper</TT> (to avoid parsing twice the files)<br>
+ Proceed as follow :<br>
+ <pre>
+ gdcmSerieHelper *sh = new gdcmSerieHelper();
+ sh->SetDirectory(myImageDirectory, true);
+ gdcmFileList *l = s->GetFirstCoherentFileList();
+ s->OrderFileList(l);
+
+ vtkGdcmReader *gr = new vtkGdcmReader();
+ gr->SetCoherentFileList(l);
+ gr->Update();
+ </pre>
+ This works with a directory that contains only one '<TT>Serie</TT>'
+ (same <TT>Serie UID</TT> for all the images).<br>
+ If it contains more than one <TT>Serie</TT>, you'll have to loop
+ on the Series, using <TT>GetNextCoherentFileList()</TT>;<br>
+ It will be up to the user to delete the <TT>gdcm::File</TT>.
+ <br><br>
+ See <TT>vtkgdcmSerieViewer</TT> for an example.
+ <br><br>
+ <LI> Both <TT>vtkgdcmViewer</TT> and <TT>vtkgdcmViewer2</TT>
+ are available to allow easy displaying of single/multiframe
+ GreyLevel/RGB/PaletteColor images<br><br>
+ <LI> <TT>DICOMDIR</TT> anonymiser (<TT>Load</TT> and <TT>Noload</TT> mode)
+ <br><br>
+ <LI> Because the <TT>gdcm::DicomDir::Load()</TT> method may be used
+ either for loading an already made <TT>DICOMDIR</TT> file or for
+ parsing all the dicom files with a given root directory we
+ syntaxically separated the operations: <br>
+ For loading an already made <TT>DICOMDIR</TT> file, use : <br>
+ <pre>
+ gdcm::DicomDir *d = new gdcm::DicomDir();
+ d->SetFileName(fileName);
+ d->Load( );
+ </pre>
+
+ For parsing all the dicom files within a given root directory, use :<br>
+ <pre>
+ gdcm::DicomDir *d = new gdcm::DicomDir();
+ d->SetDirectoryName(dirName);
+ d->Load( )
+ </pre>
+
+ <b>Don't</b> use any longer old deprecated style: <br>
+ <TT>
+ gdcm::DicomDir *d = new gdcm::DicomDir();<br>
+ d->SetParseDir(true); // </TT>or <TT>d->SetParseDir(false);<br>
+ d->Load( fileName );<br>
+ </TT>
+ <br>
+ <LI> User is now allowed to tell <TT>gdcm::Document</TT> constructor
+ he doesn't want to deal with <TT>SeqEntry</TT>
+ (every time it's possible, i.e for 'true length' Sequences) <br>
+ and/or he doesn't want to deal with <TT>Shadow groups</TT>
+ (every time it's possible i.e. when element <TT>0x0000</TT>
+ exists for this Group) <br>
