+ <UL>
+ <LI> To be able to use gdcm1.3.x and ITK, developer is now allowed to

+ option.
+ <LI> JPEG and JPEG2000 compression writting are now available.
+ see Examples/WriteDicomAsJPEG.cxx and Examples/WriteDicomAsJPEG2000.cxx
+ <LI> To <i>try to</i> make gdcm images PACS usable, user is now allowed to

+ <TT>void FileHelper::SetContentType (ImageContentType c);</TT> <br>

+ c : <TT>UNMODIFIED_PIXELS_IMAGE</TT>
+ </UL>
+ <LI> Stupid difference between <TT>gdcm::ValEntry</TT>
+ and <TT>gdcm::BinEntry</TT> removed. <br>
+ Only <TT>gdcm::DataEntry</TT> exist, now.
+ Should have been considered as a 'Bug Fix'.<br>
+ Actually, it's an API breaking modification ...
+ <UL>
+ <LI>

+ </UL>
+ <LI>
+ <TT>DocEntrySet::GetEntryValue()</TT> replaced by
+ <TT>DocEntrySet::GetEntryString()</TT> <br>
+ <LI> SerieHelper : <br>
+ Add some methods, to split a 'SingleSerieUID' Fileset into
+ 'Extra Coherent' FileSets. <br>
+ They return a std::map of 'Filesets' (actually : std::vector
+ of gdcm::File*)<br>
+ The key is the 'Orientation', the 'Position'

+ uint16_t group, uint16_t element);
+ </TT><br>
+ These methods must be called by user, depending on what he wants

+ contain !-
+ <LI> To avoid memory leaks and seg faults the user intended classes
+ use now a Reference Counter.<br>
+ <UL>
+ <LI> <TT>new()</TT> and <TT>delete()</TT> are replaced by
+ <TT>New()</TT> and <TT>Delete()</TT>
+ <LI> <TT>Register()</TT> and <TT>Unregister()</TT> methods are
+ available.
+ <LI> --> Well ... People from ITK don't seem to agree too much with
