21 We know the following are missing; don't loose time looking for them ...<br>
22 We know they could be helpfull. We shall add them some day.<br>
23 Any contribution is welcome.
26 <LI> gdcm doesn't read yet JPEG-LS and JPEG2000 encoded files.
27 <LI> Allow user to tell <TT>gdcm::Document</TT> constructor he just wants
28 to load a given list of <TT>DocEntries</TT> (to save CPU time and RAM
30 <LI> Allow user to tell the Writer he doesn't want to write down
31 <TT>SeqEntry</TT> (if any)
32 <LI> Allow user to tell the Writer he doesn't want to write down
33 <TT>Shadow groups</TT> (if any)
34 <LI> <TT>Icon Image</TT> management (Read and Write)
35 <LI> <TT>DICOMDIR</TT> full management (not limited to
36 <TT> PATIENT</TT>/<TT>STUDY</TT>/<TT>SERIE</TT>/<TT>IMAGE</TT>)
37 <LI> Allow user to add an Entry to the default entry list, before
38 making a <TT>DICOMDIR</TT> from a root directory
39 <LI> 16-bits-LUT full Management
40 <LI> User friendly management of <TT>Rescale Slope</TT> and
41 <TT>Rescale Intercept</TT>
42 <LI> Allow parsing the <TT>Shadow groups</TT> against a user supplied
43 private <TT>Dicom Dictionary</TT> (pfff!...)
44 <LI> An accurate <TT>SerieHelper</TT>
45 <LI> A <TT>SerieHelper</TT> that would use the <TT>DICOMDIR</TT> (if any)
46 instead of parsing all the files within the Root Directory

61 <a href="uml-gdcm.pdf">gdcm UML Class Diagram</a> current version.
67 <LI>Both <TT>vtkgdcmViewer</TT> and <TT>vtkgdcmViewer2</TT>
68 are available to allow easy displaying of single/multiframe
69 GreyLevel/RGB/PaletteColor images
70 <LI> <TT>DICOMDIR</TT> anonymiser (<TT>Load</TT> and <TT>Noload</TT> mode) <LI> User is now allowed to tell <TT>gdcm::Document</TT> constructor
71 he doesn't want to deal with <TT>SeqEntry</TT>
72 (every time it's possible) <br> and/or he doesn't
73 want to deal with <TT>Shadow groups</TT> (every time it's
76 gdcm::File *f = new gdcm::File();<br>
77 f->SetLoadMode(NO_SEQ | NO_SHADOW);<br>
78 f->Load(fileName);<br>
82 gdcm::File *f = new gdcm::File(fileName);</TT>
90 <LI> The difference between <TT>MONOCHROME1</TT> (low values = bright,
91 high values = dark) and <TT>MONOCHROME2</TT> (low values = dark,
92 high values = bright) is now taken into account.<br>
93 It's no longer up to the user to change the pixels value
94 <LI> Writing a 'True Dicom' image after reading an ACR-NEMA image
95 does not request any longer from the user to build up
96 'manually' the Meta Elements group (0002)
97 <LI> Old '24 Bits' ACR-NEMA are now correctly re-written in DICOM mode.
98 <LI> Element 0x0000 of <TT>Shadow groups</TT> is always forced to be a
99 <TT>ValEntry</TT> and its VR is forced to <TT>UL</TT>
103 <LI> A.P.I. breaking modifications (since previous version : <TT>1.0</TT>)
105 <LI> NEVER more API breaking modifications !!!

198 This version will be used by Insight Tool Kit
199 (<a href="http://www.itk.org">ITK</a> 2.0) at the beginning of 2005.<br>
200 It's not yet packaged ...<br><br>

202 <LI> <a href= "Doc0.6/html.developper/index.html">Developper Documentation"</a>
203 <LI> The new <TT>gdcmDocument</TT> class is a parent class of
204 <TT>gdcmHeader</TT> class and <TT>gdcmDicomDir</TT> class.
205 <LI> Massive modifications in the Class Diagram :
207 <LI> any dicom related file is a <TT>gdcmDocument</TT>
208 <LI> a <TT>gdcmDocument</TT> can be :
210 <LI> a <TT>gdcmHeader</TT>, if it contains pixel data
211 <LI> a <TT>gdcmDicomDir</TT>, if it contains only informations
212 on the files in a given directory
215 <LI> a <TT>gdcmDocument</TT> is_a <TT>gdcmElementSet</TT>,
216 composed of a set of <TT>gdcmEntry</TT> separated into :
218 <LI> <TT>gdcmValEntry</TT><br>
219 a specialization of <TT>gdcmValEntry</TT>, for 'non
220 <TT>std::string</TT> representable' values is
221 <TT>gdcmBinEntry</TT>
222 <LI> <TT>gdcmSeqEntry</TT> (VR = <TT>SQ</TT>, i.e Dicom Sequences)<br>
223 they are dealt as tree-like structures :<br>
224 - a <TT>gdcmSeqEntry</TT> is considered as a set
225 of <TT>gdcmSQItem</TT>,<br>
226 - a <TT>gdcmSQItem</TT> is_a <TT>gdcmElementSet</TT>, composed
227 of <TT>gdcmDocEntries</TT>, recursively <br>
230 <LI> Improvement of the jpeg sub-library: jpeg
231 compressed Dicom files (lossless and lossy)
232 might be read (check-it out)

247 <LI> Introduction of a jpeg sub-library: some very simple jpeg-lossy
248 compressed Dicom files might be working (check-it out).
249 <LI> And also, fewer memory leaks, cleaned-up stl usage (should work
250 with gcc-3.x), python disutil installer (see file setup.py)
251 supporting both Swig and vtk wrapping.
252 <LI> Introduction of a RLE (Run-Time Encoding) library
253 <LI> Color images (RGB or Palette Color) are dealt with
254 <LI> Confusing names <TT>gdcmPatient</TT>, <TT>gdcmStudy</TT>,
255 <TT>gdcmSerie</TT>, <TT>gdcmPatient</TT> changed to

268 <LI> <TT>gdcmFile</TT> class now enables acces to the data
269 i.e. the image[s] content. Previously only parsing of the
270 Dicom header was available through usage of <TT>gdcmHeader</TT>
272 <LI> a <A HREF="http://public.kitware.com/VTK/">VTK</A> plugin
273 of gdcm is now available through the <TT>vtkGdcmReader</TT>
274 vtk class (see it as a vtk wrapper of gdcm), which enables
276 <LI> Loading of a single image,
277 <LI> Loading of a stack of images from multiple Dicom files,
278 <LI> this class is wrapped for vtkPython (by using native vtk
281 <LI> Introduction of a jpeg sub-library: lossless-jpeg
282 compressed Dicom files work.
283 <LI> <TT>vtkgdcmViewer</TT> allows easy displaying of single/multiframe
284 GreyLevel/RGB/PaletteColor images
