21 <LI> Final check of the jpeg sub-library: all 'classical' jpeg
22 compressed Dicom files can be read<br>
23 All the previously gdcm-breaker images are now readable<br>
24 gdcm doesn't read yet JPEG-LS and JPEG2000 encoded files.
25 <LI> Use of <TT> namespace</TT> : all the methods formerly called
26 <TT>className::gdcmXxx()</TT> are now called <TT>className::Xxx()</TT>
27 <LI> Removal of accessors <TT>GetXxxByname</TT>, <TT>SetXxxByname</TT>
28 and <TT>GetXxxByNumber</TT>, <TT>SetXxxByNumber</TT>
29 replaced by <TT>GetXxx</TT>, <TT>SetXxx</TT>
30 <LI> a gdcm::Document is now specialized in gdcm::DicomDir and gdcm::File
31 <LI> A huge number of memory leaks removed
32 <LI> Improvement of write process
36 For people who get this new release :
38 We consider now that :
39 - any dicom related file is a gdcm::Document.
40 - a gdcm::Document can be :
41 - a gdcm::File, if it contains pixel data,
42 - a gdcm::DicomDir, if it contains only informations
43 on the files in a given directory
44 - in a gdcm::Document, there are gdcm::DocEntry, that can be :
45 - gdcm::ValEntry (whose value is std::string representable
46 i.e. character values, or integers),
47 - gdcm::BinEntry (whose value is not std::string representable
48 i.e. color palettes, overlays, icons , ...)
49 - gdcm::Sequence (no proper 'value', but a set of gdcm::SQItems,
50 composed of a set of gdc::DocEntry, recursively)
51 - in a gdcm::DicomDir, we only deal, hierachically, with :

71 <LI> The new <TT>gdcmDocument</TT> class is a parent class of
72 <TT>gdcmHeader</TT> class and <TT>gdcmDicomDir</TT> class.
73 <LI> Massive modifications in the Class Diagram :
75 <LI> Entries (<TT>gdcmEntry</TT>) are now separated into
76 <TT>ValEntry</TT> and <TT>SeqEntry</TT> (whose VR =

79 composed of a set of <TT>gdcmValEntry</TT>

81 <LI> a <TT>gdcmSeqEntry</TT> is considered as a set
82 of <TT>gdcmSQItem</TT>
83 <LI> Dicom Sequences (VR = <TT>SQ</TT>) are now dealt as tree-like
84 structures within <TT>gdcmSQItem</TT> class.<br>
85 they are considered as a set of <TT>gdcmSQItem</TT>s
86 <LI> a <TT>gdcmSQItem</TT> is_a <TT>gdcmElementSet</TT>
88 <LI> Improvement of the jpeg sub-library: jpeg
89 compressed Dicom files (lossless and lossy)
90 might be read (check-it out)
