Gdcm News

+ + + +

+ + Missing features +

+We know the following are missing; don't loose time looking for them ...
+We know they could be helpfull. We shall add them some day.
+Any contribution is welcome. +

Decoders +
- gdcm doesn't read yet JPEG-LS encoded files. +
  +
- gdcm doesn't read yet JPEG2000 encoded files. +
  +
- gdcm doesn't read yet MPEG2 encoded files. +
  +
+
Reader +
- Allow user to tell gdcm::Document constructor he just wants + to load a given list of DocEntries + (to save CPU time and RAM space) +
- Allow 'frame by frame' reading (should be helpfull for huge + multiframe images) +
- Allow subvolume selection / frames selection before reading. +
- Expose Read/Decompression mechanisms to allow user getting + information from DICOMDIR
  -or from his own Data Base- + and reading his images without parsing + the header, one more time. +
+
Writer +
- Allow user to tell the Writer he doesn't want to write down + SeqEntry (if any) +
- Allow user to tell the Writer he doesn't want to write down + Shadow groups (if any) +
- Allow user to tell the Writer which compression mode he wants
  + (Right now, no one is available) +
- Allow user to tell the Writer he wants to split a + Multiframe image into a serie of + Single frame images. +
- Allow user to tell the Writer he wants to agregate a + Serie of Single frame images into a + Multiframe image. +
+
Reader / Writer +
- Full Icon Image management (Read and Write) +
- Full Overlays management (Read and Write)
  + both for 'ACR-NEMA style' (using groups 0x6000 + and nexts) and 'DICOM V3 style' (using Sequences) +
+
DICOMDIR +
- DICOMDIR full management (not limited to + PATIENT/STUDY/SERIE/IMAGE) +
- Allow user to add an entry (belonging to the file header Dicom + entries)to the default entry list, before + making a DICOMDIR from a root directory +
- Allow user to add an entry of his owns (for instance an Icon + to each image, or to each Serie). +
+
SerieHelper +
- An accurate SerieHelper
  + Right now SerieHelper only works on 'bona fide Series', and + breaks on wrongly forged Series.
  + We are still looking for any heuristics... +
- A SerieHelper that would use the DICOMDIR (if any) + instead of parsing all the files within the Root Directory +
+
Other +
- 16-bits-LUT full Management +
- User friendly management of Rescale Slope and + Rescale Intercept +
- Allow parsing the Shadow groups against a user supplied + private Dicom Dictionary (pfff!...) +
+

+ +

+ + Current Version + +

+ +

State of the art +
- + gdcm UML Class Diagram current version. +
- +
+ +
New Features +
- Both vtkgdcmViewer and vtkgdcmViewer2 + are available to allow easy displaying of single/multiframe + GreyLevel/RGB/PaletteColor images +
- DICOMDIR anonymiser (Load and Noload mode) +
- User is now allowed to tell gdcm::Document constructor + he doesn't want to deal with SeqEntry + (every time it's possible)
  and/or he doesn't + want to deal with Shadow groups (every time it's + possible)
  + use :
  + gdcm::File *f = new gdcm::File(); + f->SetLoadMode(NO_SEQ | NO_SHADOW); + f->Load(fileName); + + instead of :
  + + gdcm::File *f = new gdcm::File(fileName);
  + (old style still available) + +
- User is now allowed to tell gdcm::DicomDir constructor + he doesn't want to deal with SeqEntry + (every time it's possible)
  and/or he doesn't + want to deal with Shadow groups (every time it's + possible)
  + use :
  + gdcm::DicomDir *dcmdir = new gdcm::DicomDir( ); + dcmdir->SetParseDir(true); + dcmdir->SetLoadMode(NO_SEQ | NO_SHADOW); + dcmdir->Load(dirName); + + instead of :
  + + gdcm::DicomDir *dcmdir = new gdcm::DicomDir(dirName, true);
  + (old style still available) +
- +
+ +
Bug fixes +
- The difference between MONOCHROME1 (low values = bright, + high values = dark) and MONOCHROME2 (low values = dark, + high values = bright) is now taken into account.
  + It's no longer up to the user to change the pixels value +
- Writing a 'True Dicom' image after reading an ACR-NEMA image + does not request any longer from the user to build up + 'manually' the Meta Elements group (Ox0002) +
- Old '24 Bits' ACR-NEMA are now correctly re-written + in DICOM V3 mode. +
- Element 0x0000 of Shadow groups is always forced to be a + ValEntry and its VR is forced to UL +
- +
+ +
A.P.I. breaking modifications (since previous version : 1.0) +
- NEVER more API breaking modifications !!! + +
+ +
Known bugs +
- Use of Implicit Value Representation writting mode may + causes troubles, when there are some SQ belonging to a + Shadow Group.
  + Better you use Explicit Value Representation writting mode ... +
+ +

+ + + + +

+ + Version 1.0 (Feb 14 2005) +

State of the art +
- + gdcm 1.0 UML Class Diagram version. +
- User Documentation" +
- Developper + Documentation" +
- Final check of the jpeg sub-library: all 'classical' jpeg + compressed Dicom files can be read
  +
- All the previously gdcm-breaker images are now readable
  +
- A huge number of memory leaks removed +
- Improvement of write process +
+ + +
A.P.I. breaking modifications (since previous version : 0.6) +
- Use of namespace : all the methods formerly named + className::gdcmXxx() are now named className::Xxx() +
  End user will have to call them as gdcm::className::Xxx() +
- a gdcm::Document is now specialized in : +
  - gdcm::DicomDir +
  - gdcm::File +
  +
- a gdcm::DicomElementSet is composed of a set of + gdcm::DicomDocEntry +
- a gdcm::DicomDocEntry can be : +
  - a gdcm::ContentEntry, specialized in : +
    - gdcm::ValEntry +
    - gdcm::BinEntry (no longer a specialization of + gdcm::ValEntry) +
    +
  - a gdcm::SeqEntry +
  +
- Removal of useless accessors GetXxxByname, SetXxxByname +
- Renaming of accessors GetXxxByNumber, SetXxxByNumber + as follow : +
  - GetEntryByNumber + + --> GetEntryValue +
  - GetEntryLengthByNumber --> GetEntryLength +
  - GetEntryOffsetByNumber --> GetEntryOffset +
  - GetEntryVRByNumber + --> GetEntryVR +
  - +
  - GetDocEntryByNumber + --> GetDocEntry +
  - GetValEntryByNumber + --> GetValEntry +
  - GetBinEntryByNumber + --> GetBinEntry +
  - GetSeqEntryByNumber + --> GetSeqEntry +

User Documentation" +
Developper Documentation" +
The new gdcmDocument class is a parent class of + gdcmHeader class and gdcmDicomDir class. +
Massive modifications in the Class Diagram : +
- any dicom related file is a gdcmDocument +
- a gdcmDocument can be : +
  - a gdcmHeader, if it contains pixel data +
  - a gdcmDicomDir, if it contains only informations + on the files in a given directory +
  + +
- a gdcmDocument is_a gdcmElementSet, + composed of a set of gdcmEntry separated into : +
  - gdcmValEntry
    + a specialization of gdcmValEntry, for 'non + std::string representable' values is + gdcmBinEntry +
  - gdcmSeqEntry (VR = SQ, i.e Dicom Sequences)
    + they are dealt as tree-like structures :
    + - a gdcmSeqEntry is considered as a set + of gdcmSQItem,
    + - a gdcmSQItem is_a gdcmElementSet, composed + of gdcmDocEntries, recursively

Improvement of the jpeg sub-library: jpeg + compressed Dicom files (lossless and lossy) + might be read (check-it out) +

Version 0.4 (February 6 2004)

gdcmFile class now enables acces to the data - i.e. the image[s] content. Previously only parsing of the - Dicom header was available through usage of gdcmHeader - class. -
a VTK plugin - of gdcm is now available through the vtkGdcmReader - vtk class (see it as a vtk wrapper of gdcm), which enables -
- Loading of a single image, -
- Loading of a stack of images from multiple Dicom files, -
- this class is wrapped for vtkPython (by using native vtk - wrappers). -
