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 doesn't
28 want to deal with <TT>SeqEntry</TT (every time it's possible)
29 <LI> Allow user to tell <TT>gdcm::Document</TT> constructor he doesn't
30 want to deal with <TT>Shadow groups</TT>
31 <LI> Allow user to tell <TT>gdcm::Document</TT> constructor he just wants
32 to load a given list of <TT>DocEntries</TT> (to save CPU time and RAM
34 <LI> Allow user to tell the Writer he doesn't want to write down
35 <TT>SeqEntry</TT> (if any)

56 <B>Current Version</B></A>
64 <a href="uml-gdcm.pdf">gdcm UML Class Diagram</a> current version.
70 <LI>Both <TT>vtkgdcmViewer</TT> and <TT>vtkgdcmViewer2</TT>
71 are available to allow easy displaying of single/multiframe
72 GreyLevel/RGB/PaletteColor images
77 <LI> The difference between <TT>MONOCHROME1</TT> (low values = bright,
78 high values = dark) and <TT>MONOCHROME2</TT> (low values = dark,
79 high values = bright) is now taken into account.<br>
80 It's no longer up to the user to change the pixels value
81 <LI> Writing a 'True Dicom' image after reading an ACR-NEMA image
82 does not request any longer from the user to build up
83 'manually' the Meta Elements group (0002)
84 <LI> Old '24 Bits' ACR-NEMA are now correctly re-written in DICOM mode.
88 <LI> A.P.I. breaking modifications (since previous version : <TT>1.0</TT>)
90 <LI> NEVER more API breaking modifications !!!

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

187 <LI> <a href= "Doc0.6/html.developper/index.html">Developper Documentation"</a>
188 <LI> The new <TT>gdcmDocument</TT> class is a parent class of
189 <TT>gdcmHeader</TT> class and <TT>gdcmDicomDir</TT> class.
190 <LI> Massive modifications in the Class Diagram :
192 <LI> any dicom related file is a <TT>gdcmDocument</TT>
193 <LI> a <TT>gdcmDocument</TT> can be :
195 <LI> a <TT>gdcmHeader</TT>, if it contains pixel data
196 <LI> a <TT>gdcmDicomDir</TT>, if it contains only informations
197 on the files in a given directory

206 <TT>gdcmBinEntry</TT>
207 <LI> <TT>gdcmSeqEntry</TT> (VR = <TT>SQ</TT>, i.e Dicom Sequences)<br>
208 they are dealt as tree-like structures :<br>
209 - a <TT>gdcmSeqEntry</TT> is considered as a set

232 <LI> Introduction of a jpeg sub-library: some very simple jpeg-lossy
233 compressed Dicom files might be working (check-it out).
234 <LI> And also, fewer memory leaks, cleaned-up stl usage (should work
235 with gcc-3.x), python disutil installer (see file setup.py)
236 supporting both Swig and vtk wrapping.

238 <LI> Color images (RGB or Palette Color) are dealt with
239 <LI> Confusing names <TT>gdcmPatient</TT>, <TT>gdcmStudy</TT>,
240 <TT>gdcmSerie</TT>, <TT>gdcmPatient</TT> changed to

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