+ Documentation</a>
+ <LI> New Features
+
+ <UL>
+ <LI> To be able to use gdcm1.3.x and ITK, developer is now allowed to
+ choose his own namespace for gdcm at CMake time : see GDCM_NAME_SPACE
+ option.
+ <LI> JPEG and JPEG2000 compression writting are now available.
+ see Examples/WriteDicomAsJPEG.cxx and Examples/WriteDicomAsJPEG2000.cxx
+ <LI> To <i>try to</i> make gdcm images PACS usable, user is now allowed to
+ gdcm what kind of image he wants to write, using : <br>
+ <TT>void FileHelper::SetContentType (ImageContentType c);</TT> <br>
+ Four different types are identifyed (probabely more will be added) :
+ <UL>
+ <LI>
+ 1) user created ex nihilo his own image and wants to write it as a Dicom image.<br>
+ c : <TT>USER_OWN_IMAGE</TT>
+ <LI>
+ 2) user modified the pixels of an existing image, using mathematical operations.<br>
+ c : <TT>FILTERED_IMAGE</TT>
+ <LI>
+ 3) user created a new image, using existing images (eg MIP, MPR, cartography image)<br>
+ c : <TT>CREATED_IMAGE</TT>
+ <LI>
+ 4) user modified/added some tags *without processing* the pixels (anonymization, etc)<br>
+ c : <TT>UNMODIFIED_PIXELS_IMAGE</TT>
+ </UL>
+ <LI> Stupid difference between <TT>gdcm::ValEntry</TT>
+ and <TT>gdcm::BinEntry</TT> removed. <br>
+ Only <TT>gdcm::DataEntry</TT> exist, now.
+ Should have been considered as a 'Bug Fix'.<br>
+ Actually, it's an API breaking modification ...
+ <UL>
+ <LI>
+ <TT>std::string const &DataEntry::GetString() const</TT><br>
+ returns as a string (when possible) the value of the DataEntry
+ <LI>
+ <TT>void DataEntry::SetString(std::string const &value)</TT><br>
+ Sets the 'value' of a DataEntry, passed as a std::string
+ <LI>

+ Sets the value (non string) of the current Dicom DataEntry
+ <LI>
+ <TT>void DataEntry::CopyBinArea( uint8_t *area, uint32_t length )</TT><br>
+ Inserts the value (non string) into the current DataEntry
+ <LI>
+ <TT>void DataEntry::SetValue(const uint32_t &id, const double
+ &val)</TT><br>
+ Inserts the elementary (non string) value into the current
+ (multivaluated) DataEntry, at the <TT>id></TT> position.
+ <LI>
+ <TT>double DataEntry::GetValue(const uint32_t &id) const </TT><br>
+ returns, as a double one of the values (when entry is
+ multivaluated), identified by its index <TT>id</TT>.
+ </UL>
+ <LI>
+ <TT>DocEntrySet::GetEntryValue()</TT> replaced by
+ <TT>DocEntrySet::GetEntryString()</TT> <br>
+ <LI> SerieHelper : <br>
+ Add some methods, to split a 'SingleSerieUID' Fileset into
+ 'Extra Coherent' FileSets. <br>
+ They return a std::map of 'Filesets' (actually : std::vector
+ of gdcm::File*)<br>
+ The key is the 'Orientation', the 'Position'
+ or the value of a user choosen 'Tag' <br>
+ - <TT>XCoherentFileSetmap SplitOnOrientation(FileList *fileSet);
+ </TT><br>
+ - <TT>XCoherentFileSetmap SplitOnPosition(FileList *fileSet);
+ </TT> <br>
+ - <TT>XCoherentFileSetmap SplitOnTagValue(FileList *fileSet,
+ uint16_t group, uint16_t element);
+ </TT><br>
+ These methods must be called by user, depending on what he wants
+ to do, at application time.- *he* only knows what his Series
+ contain !-
+ <LI> To avoid memory leaks and seg faults the user intended classes
+ use now a Reference Counter.<br>
+ <UL>
+ <LI> <TT>new()</TT> and <TT>delete()</TT> are replaced by
+ <TT>New()</TT> and <TT>Delete()</TT>
+ <LI> <TT>Register()</TT> and <TT>Unregister()</TT> methods are
+ available.
+ <LI> --> Well ... People from ITK don't seem to agree too much with
+ that feature.<br>
+ They demand to be allowed to allocate gdcm objects in the stack as
+ well, not only in the heap.

+ Many users expect from <TT>vtkGdcmReader</TT> it 'orders' the images

+ 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 :

+ gdcm::SerieHelper *sh= new gdcm::SerieHelper();
+ // if user wants *not* to load some parts of the file headers

+
+ // if user wants *not* to load some files

+
+ // here, we suppose only the first 'Single SerieUID' Fileset is of interest

+ // if user is doesn't trust too much the files with same Serie UID

+ sh->OrderFileList(l); // sort the list
+
+ vtkGdcmReader *reader = vtkGdcmReader::New();

+ // 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>

+
+ <TT>vtkgdcmSerieViewer dirname=Dentist mirror</TT><br>
+ <TT>vtkgdcmSerieViewer dirname=Dentist reverse</TT><br>
+ <TT>vtkgdcmSerieViewer dirname=Dentist reverse topdown</TT><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

+ 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.

+ <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>

+ anonymizes all the files within the given Directory.
+ <br>

+ <TT>rubout=listOfElementsToRubOut</TT><br>
+ with <tt>listOfElementsToRubOut : group1-elem1,group2-elem2,
+ ...</TT> (in hexa, no space within the list )

+ <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

+ 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>

-For people who get this new release :
-
-We consider now that :
-- any dicom related file is a gdcm::Document.
-- a gdcm::Document can be :
- - a gdcm::File, if it contains pixel data,
- - a gdcm::DicomDir, if it contains only informations
- on the files in a given directory
-
-- in a gdcm::Document, there are gdcm::DocEntry, that can be :
- - gdcm::ContentEntry (any entry that has an actual value,
- *not* an embedded set of other gdcm::DocEntry)
- a gdcm::ContentEntry can be :
- - gdcm::ValEntry (whose value is std::string representable
- e.g. character values, or integers),
- - gdcm::BinEntry (whose value is not std::string representable
- e.g. color palettes, overlays, icons , ...)
- - gdcm::Sequence (no proper 'value', but a set of gdcm::SQItems,
- composed of a set of gdc::DocEntry, recursively)
-
-- in a gdcm::DicomDir, we only deal, hierarchically, with :
- - gdcmPatient
- - gdcmStudy
- - gdcmSerie
- - gdcmImage
