- Current Version + Current Version (CVS) : gdcm1.3.2

Missing Features +
Differences between gdcm 1.3.1 and gdcm 1.3.2 +
- Uncorrect reading/writting of JPEG/JPE2000 images when + BitsAllocated=16/BitsStored=8 +
- Uncorrect writing of JPEG/JPE2000 image with an 'Icon' Sequence +
- Uncorrect writting of JPE2000 multiframe images +
- Uncorrect writting of images with a DataElement belonging to group + 0002, inside a Sequence +
- Uncorrect re-writting of Implicit Value Representation images with + 'shadow groups' when Explicit Value Representation was asked + (unexpected swap to Implicit VR) +
+ If you experience troubles with gdcm-written images, check which + gdcm version was used (PrintFile filein=yourFileName.dcm) +
State of the art
- - gdcm UML Class Diagram current version. - + gdcm UML Class Diagram current version. +
- User Documentation +
- Developper + Documentation +
- New Features + +
  - 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. +
  - JPEG and JPEG2000 compression writting are now available. + see Examples/WriteDicomAsJPEG.cxx and Examples/WriteDicomAsJPEG2000.cxx +
  - To try to make gdcm images PACS usable, user is now allowed to + gdcm what kind of image he wants to write, using :
    + void FileHelper::SetContentType (ImageContentType c);
    + Four different types are identifyed (probabely more will be added) : +
    - + 1) user created ex nihilo his own image and wants to write it as a Dicom image.
      + c : USER_OWN_IMAGE +
    - + 2) user modified the pixels of an existing image, using mathematical operations.
      + c : FILTERED_IMAGE +
    - + 3) user created a new image, using existing images (eg MIP, MPR, cartography image)
      + c : CREATED_IMAGE +
    - + 4) user modified/added some tags *without processing* the pixels (anonymization, etc)
      + c : UNMODIFIED_PIXELS_IMAGE +
    +
  - Stupid difference between gdcm::ValEntry + and gdcm::BinEntry removed.
    + Only gdcm::DataEntry exist, now. + Should have been considered as a 'Bug Fix'.
    + Actually, it's an API breaking modification ... +
    - + std::string const &DataEntry::GetString() const
      + returns as a string (when possible) the value of the DataEntry +
    - + void DataEntry::SetString(std::string const &value)
      + Sets the 'value' of a DataEntry, passed as a std::string +
    - + void DataEntry::SetBinArea( uint8_t *area, bool self )
      + Sets the value (non string) of the current Dicom DataEntry +
    - + void DataEntry::CopyBinArea( uint8_t *area, uint32_t length )
      + Inserts the value (non string) into the current DataEntry +
    - + void DataEntry::SetValue(const uint32_t &id, const double + &val)
      + Inserts the elementary (non string) value into the current + (multivaluated) DataEntry, at the id> position. +
    - + double DataEntry::GetValue(const uint32_t &id) const
      + returns, as a double one of the values (when entry is + multivaluated), identified by its index id. +
    +
  - + DocEntrySet::GetEntryValue() replaced by + DocEntrySet::GetEntryString()
    +
  - SerieHelper :
    + Add some methods, to split a 'SingleSerieUID' Fileset into + 'Extra Coherent' FileSets.
    + They return a std::map of 'Filesets' (actually : std::vector + of gdcm::File*)
    + The key is the 'Orientation', the 'Position' + or the value of a user choosen 'Tag'
    + - XCoherentFileSetmap SplitOnOrientation(FileList *fileSet); +
    + - XCoherentFileSetmap SplitOnPosition(FileList *fileSet); +
    + - XCoherentFileSetmap SplitOnTagValue(FileList *fileSet, + uint16_t group, uint16_t element); +
    + These methods must be called by user, depending on what he wants + to do, at application time.- *he* only knows what his Series + contain !- +
  - To avoid memory leaks and seg faults the user intended classes + use now a Reference Counter.
    +
    - new() and delete() are replaced by + New() and Delete() +
    - Register() and Unregister() methods are + available. +
    - --> Well ... People from ITK don't seem to agree too much with + that feature.
      + They demand to be allowed to allocate gdcm objects in the stack as + well, not only in the heap. +

A.P.I. breaking modifications (since previous version : 1.0) -
- State of the art +
  - + gdcm 1.2 UML Class Diagram version + (same as 1.1) +
  - This is the Class Diagram of the version used within ITK. + (Hope we unify CVS version and ITK version, some day!) + + + +
    +
    + + Version 1.1 (September 14 2005) +
    +
  - State of the art +
    - + gdcm 1.1 UML Class Diagram version. +
    - User Documentation +
    - Developper + Documentation +
    - New Features +
      - Add the methods + gdcm::Dict:AddDict(std::string fullPathPrivateDictionaryFileName) +
        and
        + gdcm::Dict::RemoveDict(std::string fullPathPrivateDictionaryFileName) +
        + to allow user to choose the 'Private Dictionary' he wants to work with. +
        + One can dream about a better API;
        + 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. +
        
        +
      - + 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 +
      - + (Not a great one ...) + Stupid method names :
        DicomDir::WriteDicomDir() + and DicomDir::AnonymizeDicomDir()
        replaced by :
        + DicomDir::Write() + and DicomDir::Anonymize() +
        
        +
      - + void Document::AddForceLoadElement(uint16_t group, uint16_t elem); +
        + allows user to tell gdcm::Document Loader he wants + to force the loading of a given set of DocEntries, + even if their length exceeds the current + 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. +
        
        +
      - Both vtkgdcmViewer and vtkgdcmViewer2 + are available to allow easy displaying of single/multiframe + GreyLevel/RGB/PaletteColor images
        
        +
      - DICOMDIR anonymiser (Load and Noload mode) +
        
        +
      - Because the gdcm::DicomDir::Load() method may be used + either for loading an already made DICOMDIR file or for + parsing all the dicom files with a given root directory we + syntaxically separated the operations:
        + For loading an already made DICOMDIR file, use :
        +
        + gdcm::DicomDir *d = new gdcm::DicomDir(); + d->SetFileName(fileName); + d->Load( ); +
        + + For parsing all the dicom files within a given root directory, use :
        +
        + gdcm::DicomDir *d = new gdcm::DicomDir(); + d->SetDirectoryName(dirName); + d->Load( ) +
        + + Don't use any longer old deprecated style:
        + + gdcm::DicomDir *d = new gdcm::DicomDir(); + d->SetParseDir(true); //or d->SetParseDir(false); + d->Load( fileName ); + +
        +
      - User is now allowed to tell gdcm::Document constructor + he doesn't want to deal with SeqEntry + (every time it's possible, i.e for 'true length' Sequences)
        + and/or he doesn't want to deal with Shadow groups + (every time it's possible i.e. when element 0x0000 + exists for this Group)
        + or he doesn't want to deal with SeqEntry that belong to a + Shadow group (every time it's possible + -'true length' Sequence-)
        + use :
        +
        + gdcm::File *f = new gdcm::File(); + f->SetLoadMode(NO_SEQ); | depending on what + f->SetLoadMode(NO_SHADOW); | you want *not* + f->SetLoadMode(NO_SEQ | NO_SHADOW);| to load from the + f->SetLoadMode(NO_SHADOWSEQ); | target file + f->SetFileName(fileName); + f->Load( ); +
