19 <B>Missing features</B></A>
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.
27 <LI> gdcm doesn't read yet JPEG-LS and JPEG2000 encoded files.
28 <LI> gdcm doesn't read yet MPEG encoded files.
32 <LI> Allow user to tell <TT>gdcm::Document</TT> constructor he just wants
33 to load a given list of <TT>DocEntries</TT>
34 (to save CPU time and RAM space)
35 <LI> Allow 'frame by frame' reading (should be helpfull for huge multiframe
37 <LI> Expose Read/Decompression mechanisms to allow user getting
38 information from <tt>DICOMDIR</TT> <br> -or from his own Data Base-
39 and reading his images without parsing
40 the header, one more time.
44 <LI> Allow user to tell the Writer he doesn't want to write down
45 <TT>SeqEntry</TT> (if any)
46 <LI> Allow user to tell the Writer he doesn't want to write down
47 <TT>Shadow groups</TT> (if any)
48 <LI> Allow user to tell the Writer which compression mode he wants<br>
49 (Right now, no one is available)
53 <LI> Full <TT>Icon Image</TT> management (Read and Write)
54 <LI> Full <TT>Overlays</TT> management (Read and Write) <br>
55 both for '<TT>ACR-NEMA</TT> style' (using groups <TT>0x6000</TT>
56 and nexts) and '<TT>DICOM V3</TT> style' (using Sequences)
58 <LI> <TT>DICOMDIR</TT>
60 <LI> <TT>DICOMDIR</TT> full management (not limited to
61 <TT> PATIENT</TT>/<TT>STUDY</TT>/<TT>SERIE</TT>/<TT>IMAGE</TT>)
62 <LI> Allow user to add an entry (belonging to the file header Dicom
63 entries)to the default entry list, before
64 making a <TT>DICOMDIR</TT> from a root directory
65 <LI> Allow user to add an entry of his owns (for instance an <TT>Icon</TT>
66 to each image, or to each Serie.
71 <LI> An accurate <TT>SerieHelper</TT> <br>
72 Right now <TT>SerieHelper</TT> only works on 'bona fide Series', and
73 breaks on wrongly forged Series.<br>
74 We are still looking for any heuristics...
75 <LI> A <TT>SerieHelper</TT> that would use the <TT>DICOMDIR</TT> (if any)
76 instead of parsing all the files within the Root Directory
80 <LI> 16-bits-LUT full Management
81 <LI> User friendly management of <TT>Rescale Slope</TT> and
82 <TT>Rescale Intercept</TT>
83 <LI> Allow parsing the <TT>Shadow groups</TT> against a user supplied
84 private <TT>Dicom Dictionary</TT> (pfff!...)

107 GreyLevel/RGB/PaletteColor images
108 <LI> <TT>DICOMDIR</TT> anonymiser (<TT>Load</TT> and <TT>Noload</TT> mode)
109 <LI> User is now allowed to tell <TT>gdcm::Document</TT> constructor
110 he doesn't want to deal with <TT>SeqEntry</TT>
111 (every time it's possible) <br> and/or he doesn't
112 want to deal with <TT>Shadow groups</TT> (every time it's
115 gdcm::File *f = new gdcm::File();<br>

145 high values = dark) and <TT>MONOCHROME2</TT> (low values = dark,
146 high values = bright) is now taken into account.<br>
147 It's no longer up to the user to change the pixels value
148 <LI> Writing a 'True Dicom' image after reading an <TT>ACR-NEMA</TT> image
149 does not request any longer from the user to build up
150 'manually' the Meta Elements group (<TT>Ox0002</TT>)
151 <LI> Old '24 Bits' <TT>ACR-NEMA</TT> are now correctly re-written
152 in <TT>DICOM V3</TT> mode.
153 <LI> Element <TT>0x0000</TT> of <TT>Shadow groups</TT> is always forced to be a
154 <TT>ValEntry</TT> and its <TT>VR</TT> is forced to <TT>UL</TT>

262 <LI> any dicom related file is a <TT>gdcmDocument</TT>
263 <LI> a <TT>gdcmDocument</TT> can be :
265 <LI> a <TT>gdcmHeader</TT>, if it contains pixel data

278 they are dealt as tree-like structures :<br>

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

323 <LI> <TT>gdcmFile</TT> class now enables acces to the data

325 Dicom header was available through usage of <TT>gdcmHeader</TT>
327 <LI> a <A HREF="http://public.kitware.com/VTK/">VTK</A> plugin
328 of gdcm is now available through the <TT>vtkGdcmReader</TT>
329 vtk class (see it as a vtk wrapper of gdcm), which enables

332 <LI> Loading of a stack of images from multiple Dicom files,
333 <LI> this class is wrapped for vtkPython (by using native vtk
336 <LI> Introduction of a jpeg sub-library: lossless-jpeg
337 compressed Dicom files work.
