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

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

172 <LI> <a href= "Doc0.6/html.developper/index.html">Developper Documentation"</a>
173 <LI> The new <TT>gdcmDocument</TT> class is a parent class of
174 <TT>gdcmHeader</TT> class and <TT>gdcmDicomDir</TT> class.
175 <LI> Massive modifications in the Class Diagram :
177 <LI> any dicom related file is a <TT>gdcmDocument</TT>
178 <LI> a <TT>gdcmDocument</TT> can be :
180 <LI> a <TT>gdcmHeader</TT>, if it contains pixel data
181 <LI> a <TT>gdcmDicomDir</TT>, if it contains only informations
182 on the files in a given directory
185 <LI> a <TT>gdcmDocument</TT> is_a <TT>gdcmElementSet</TT>,
186 composed of a set of <TT>gdcmEntry</TT> separated into :
188 <LI> <TT>gdcmValEntry</TT><br>
189 a specialization of <TT>gdcmValEntry</TT>, for 'non

191 <TT>gdcmBinEntry</TT>
192 <LI> <TT>gdcmSeqEntry</TT> (VR = <TT>SQ</TT>, i.e Dicom Sequences)<br>
193 they are dealt as tree-like structures :<br>
194 - a <TT>gdcmSeqEntry</TT> is considered as a set
195 of <TT>gdcmSQItem</TT>,<br>
196 - a <TT>gdcmSQItem</TT> is_a <TT>gdcmElementSet</TT>, composed
197 of <TT>gdcmDocEntries</TT>, recursively <br>

201 compressed Dicom files (lossless and lossy)
202 might be read (check-it out)

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

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