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 <TT>JPEG-LS</TT> encoded files.
29 We said '<TT>JPEG-LS</TT>', not Lossless Jpeg ...<br>
30 [<TT>JPEG-LS</TT> is the basis for new lossless/near-lossless compression
31 standard for continuous-tone images intended for <TT>JPEG2000</TT>.
32 The standard is based on the LOCO-I algorithm
33 (LOw COmplexity LOssless COmpression for Images)
34 developed at Hewlett-Packard Laboratories]
36 <LI> gdcm doesn't read yet all <TT>JPEG2000</TT> encoded files.
38 But we are working on it (a lot of troubles with Jasper).
39 Update: as of Oct 10 2005, we are currently investigating another library:
40 openjpeg. The problem still exist for this library but one of the author
41 is currently working on it:
42 http://www.openjpeg.org/forum/viewtopic.php?t=18
44 <LI> gdcm doesn't read yet <TT>MPEG2</TT> encoded files.
49 <LI> Allow user to tell <TT>gdcm::Document</TT> constructor he just wants
50 to load a given list of <TT>DocEntries</TT>
51 (to save CPU time and RAM space)
52 <LI> Allow 'frame by frame' reading (should be helpfull for huge
54 <LI> Allow subvolume selection / frames selection before reading.
55 <LI> Expose Read/Decompression mechanisms to allow user getting
56 information from <tt>DICOMDIR</TT> <br> -or from his own Data Base-
57 and reading his images without parsing
58 the header, one more time.
62 <LI> Allow user to tell the Writer he doesn't want to write down
63 <TT>SeqEntry</TT> (if any)
64 <LI> Allow user to tell the Writer he doesn't want to write down
65 <TT>Shadow groups</TT> (if any)
66 <LI> Allow user to tell the Writer which compression mode he wants<br>
67 (Right now, no one is available)
68 <LI> Allow user to tell the Writer he wants to split a
69 <TT>Multiframe</TT> image into a serie of
70 <TT>Single frame</TT> images.
71 <LI> Allow user to tell the Writer he wants to agregate a
72 Serie of <TT>Single frame</TT> images into a
73 <TT>Multiframe</TT> image.
77 <LI> Full <TT>Icon Image</TT> management (Read and Write)
78 <LI> Full <TT>Overlays</TT> management (Read and Write) <br>
79 both for '<TT>ACR-NEMA</TT> style' (using groups <TT>0x6000</TT>
80 and next) and '<TT>DICOM V3</TT> style' (using Sequences)
82 <LI> <TT>DICOMDIR</TT>
84 <LI> <TT>DICOMDIR</TT> full management (not limited to
85 <TT> PATIENT</TT>/<TT>STUDY</TT>/<TT>SERIE</TT>/<TT>IMAGE</TT>)
86 <LI> Allow user to add an entry (belonging to the file header Dicom
87 entries)to the default entry list, before
88 making a <TT>DICOMDIR</TT> from a root directory
89 <LI> Allow user to add an entry of his owns (for instance an <TT>Icon</TT>
90 to each image, or to each Serie).
95 <LI> An accurate <TT>SerieHelper</TT> <br>
96 Right now <TT>SerieHelper</TT> only works on 'bona fide Series', and
97 breaks on wrongly forged Series.<br>
98 We are still looking for any heuristics...
99 <LI> A <TT>SerieHelper</TT> that would use the <TT>DICOMDIR</TT> (if any)
100 instead of parsing all the files within the Root Directory
104 <LI> 16-bits-LUT full Management
105 <LI> User friendly management of <TT>Rescale Slope</TT> and
106 <TT>Rescale Intercept</TT>
107 <LI> Allow manual adjunction / automatic recognition (pfff!...)
108 of the private <TT>Dicom Dictionary</TT>
109 to be used to parse <TT>Shadow groups</TT> against.
110 <LI> User friendly way of anonymizing image when Patient's name is
111 carved in the Pixels :-(

136 Should have been considered as a 'Bug Fix'.<br>
137 Actually, it's an API breaking modification ...
138 <LI> SerieHelper : <br>
139 Add some methods, to split a 'SingleSerieUID' Fileset into
140 'Extra Coherent' FileSets. <br>
141 They return a std::map of 'Filesets' (actually : std::vector

159 and <TT>gdcm::BinEntry</TT> removed. <br>
160 Only <TT>gdcm::DataEntry</TT> exist, now. <br>
167 <LI> Implicit VR - Big Endian (G.E Private) Transfert Syntax 16 Bits
168 images are now read correctly.
169 <LI> File::GetZOrigin() returns accurate result in any case.
176 <LI> Use of <TT>Implicit Value Representation</TT> writting mode may

178 <TT>Shadow Group</TT>. <br>
179 Better you use <TT>Explicit Value Representation</TT> writting mode ...

208 <TT>gdcm::Dict:AddDict(std::string fullPathPrivateDictionaryFileName)</TT>
210 <TT>gdcm::Dict::RemoveDict(std::string fullPathPrivateDictionaryFileName)</TT>
212 to allow user to choose the 'Private Dictionary' he wants to work with.
214 One can dream about a better API;<br>
215 This one allow right now anybody to see very easyly if the use
216 of a given private dicom dictionary is of any help or not.
219 <TT>PrintFile</TT> has now a new command line argument manager option :<br>
220 <TT>dict=fullPathNamePrivateDictionaryFile</TT><br>
221 to allow user to see with no extra coding what differences
222 makes the use or not of a private Dicom Dictionary.<br>
223 e.g. : use it as follow <br>
224 <TT>PrintFile filein=myGEdicomFile.dcm
225 dict=/user/userName/gdcm/Dicts/GEMS-Advance.dic</TT>
228 (Not a great one ...)
229 Stupid method names : <br><TT>DicomDir::WriteDicomDir()</TT>
230 and <TT>DicomDir::AnonymizeDicomDir()</TT> <br>replaced by : <br>
231 <TT>DicomDir::Write()</TT>
232 and <TT>DicomDir::Anonymize()</TT>
235 void Document::AddForceLoadElement(uint16_t group, uint16_t elem);
237 allows user to tell <TT>gdcm::Document</TT> Loader he wants
238 to force the loading of a given set of <TT>DocEntries</TT>,
239 even if their length exceeds the current
240 <TT>MAX_SIZE_LOAD_ELEMENT_VALUE</TT>.
243 Many users expect from <TT>vtkGdcmReader</TT> it 'orders' the images
244 (that's the job of <TT>gdcm::SerieHelper</TT> ...)<br>
245 When user <b>knows</b> the files with same Serie UID
246 have same sizes, same 'pixel' type, same color convention, ...
247 the right way to proceed is as follow :
249 gdcm::SerieHelper *sh= new gdcm::SerieHelper();
250 // if user wants *not* to load some parts of the file headers
251 sh->SetLoadMode(loadMode);
253 // if user wants *not* to load some files
254 sh->AddRestriction(group, element, value, operator);
255 sh->AddRestriction( ...
256 sh->SetDirectory(directoryWithImages);
258 // if user *knows* how to order his files
259 sh->SetUserLessThanFunction(userSuppliedComparisonFunction);
261 // if user wants to sort reverse order
262 sh->SetSortOrderToReverse();
264 // here, we suppose only the first 'Single SerieUID' Fileset is of interest
265 // Just iterate using sh->NextSingleSerieUIDFileSet()
266 // if you want to get all of them
267 gdcm::FileList *l = sh->GetFirstSingleSerieUIDFileSet();
269 // if user is doesn't trust too much the files with same Serie UID
270 if ( !sh->IsCoherent(l) )
271 return; // not same sizes, or not same 'pixel type' -> stop
273 sh->OrderFileList(l); // sort the list
275 vtkGdcmReader *reader = vtkGdcmReader::New();
276 // if user wants to modify pixel order (Mirror, TopDown, ...)
277 // he has to supply the function that does the job
278 // (a *very* simple example is given in vtkgdcmSerieViewer.cxx)
279 reader->SetUserFunction (userSuppliedFunction);
281 // to pass a 'Single SerieUID' Fileset as produced by gdcm::SerieHelper
282 reader->SetCoherentFileList(l);
285 You can see a full example in <TT>vtk/vtkgdcmSerieViewer.cxx</TT><br>
288 <TT>vtkgdcmSerieViewer dirname=Dentist mirror</TT><br>
289 <TT>vtkgdcmSerieViewer dirname=Dentist reverse</TT><br>
290 <TT>vtkgdcmSerieViewer dirname=Dentist reverse topdown</TT><br>
294 <LI> <TT>vtkGdcmReader::SetUserFunction (userSuppliedFunction)</TT><br>
296 <TT>void userSuppliedFunction(uint8_t *imageData, File *f);</TT><br>
297 allows user to reorganize the pixels of each image just after reading
298 it (to mirror, or topdown the image, for instance)<br>
299 Note : <TT>uint8_t *</TT> doesn't mean it works only on 8 Bits images.
300 <br> It's for prototyping. Feel free to cast it.
303 SerieHelper::SetUserLessThanFunction(userSuppliedComparisonFunction)
304 </TT><br> with : <br>
305 <TT>bool userSuppliedComparisonFunction(File *, File *);</TT><br>
306 allows user -when he knows more about his files than gdcm does-
307 to give his own comparison function.
308 <LI> <TT>SerieHelper::SetSortOrderToReverse</TT> allows user to ask
309 to sort the Files reverse order.
310 <LI> <TT>SerieHelper::AddRestriction</TT> has now a new constructor<br>
311 <TT>AddRestriction(group, element, value, operator);</TT><br>
312 allows user to exclude some files from the sorting, according to
313 any comparison operator <br>
314 (<TT>GDCM_EQUAL</TT>, <TT>GDCM_DIFFERENT</TT>,
315 <TT>GDCM_GREATER</TT>, <TT>GDCM_GREATEROREQUAL</TT>,
316 <TT>GDCM_LESS</TT>, <TT>GDCM_LESSOREQUAL</TT>), not only on the
319 <LI> <TT>AnonymizeNoLoad</TT> used with <TT>dirin=inputDirectoryName</TT>
320 anonymizes all the files within the given Directory.
322 User may also choose extra elements he wants to rub out: <br>
323 <TT>rubout=listOfElementsToRubOut</TT><br>
324 with <tt>listOfElementsToRubOut : group1-elem1,group2-elem2,
325 ...</TT> (in hexa, no space within the list )
327 <LI> <TT>gdcm::SerieHelper()</TT> has a new method
328 <TT>void AddGdcmFile(File *header)</TT>, that allows aware user to
329 create a '<TT>FileList</TT>' (actually a
330 <TT>std::vector< File* > </TT>).<br>
331 The <TT>FileList</TT> created this way will be the
332 'first one' in the <TT>gdcm::FileHelper()</TT> (retrieve it with
333 <TT>FileList *GetFirstCoherentFileList()</TT> ).<br>
334 It may be sorted using <TT>OrderFileList</TT>.<br>
335 No 'coherence check' will be performed on this <TT>FileList</TT>
337 It may be passed to a <TT>vtkGdcmReader</TT>
338 (to avoid parsing twice the files)
340 <LI> <TT>vtkGdcmReader</TT> can now get the result of
341 <TT>gdcm::SerieHelper</TT> (to avoid parsing twice the files)<br>
342 Proceed as follow :<br>
344 gdcmSerieHelper *sh = new gdcmSerieHelper();
345 sh->SetDirectory(myImageDirectory, true);
346 gdcmFileList *l = s->GetFirstCoherentFileList();
349 vtkGdcmReader *gr = new vtkGdcmReader();
350 gr->SetCoherentFileList(l);
353 This works with a directory that contains only one '<TT>Serie</TT>'
354 (same <TT>Serie UID</TT> for all the images).<br>
355 If it contains more than one <TT>Serie</TT>, you'll have to loop
356 on the Series, using <TT>GetNextCoherentFileList()</TT>;<br>
357 It will be up to the user to delete the <TT>gdcm::File</TT>.
359 See <TT>vtkgdcmSerieViewer</TT> for an example.
361 <LI> Both <TT>vtkgdcmViewer</TT> and <TT>vtkgdcmViewer2</TT>
362 are available to allow easy displaying of single/multiframe
363 GreyLevel/RGB/PaletteColor images<br><br>
364 <LI> <TT>DICOMDIR</TT> anonymiser (<TT>Load</TT> and <TT>Noload</TT> mode)
366 <LI> Because the <TT>gdcm::DicomDir::Load()</TT> method may be used
367 either for loading an already made <TT>DICOMDIR</TT> file or for
368 parsing all the dicom files with a given root directory we
369 syntaxically separated the operations: <br>
370 For loading an already made <TT>DICOMDIR</TT> file, use : <br>
372 gdcm::DicomDir *d = new gdcm::DicomDir();
373 d->SetFileName(fileName);
377 For parsing all the dicom files within a given root directory, use :<br>
379 gdcm::DicomDir *d = new gdcm::DicomDir();
380 d->SetDirectoryName(dirName);
384 <b>Don't</b> use any longer old deprecated style: <br>
386 gdcm::DicomDir *d = new gdcm::DicomDir();<br>
387 d->SetParseDir(true); // </TT>or <TT>d->SetParseDir(false);<br>
388 d->Load( fileName );<br>
391 <LI> User is now allowed to tell <TT>gdcm::Document</TT> constructor
392 he doesn't want to deal with <TT>SeqEntry</TT>
393 (every time it's possible, i.e for 'true length' Sequences) <br>
394 and/or he doesn't want to deal with <TT>Shadow groups</TT>
395 (every time it's possible i.e. when element <TT>0x0000</TT>
396 exists for this Group) <br>
397 or he doesn't want to deal with <TT>SeqEntry</TT> that belong to a
398 <TT>Shadow group</TT> (every time it's possible
399 -'true length' Sequence-)<br>
402 gdcm::File *f = new gdcm::File();
403 f->SetLoadMode(NO_SEQ); | depending on what
404 f->SetLoadMode(NO_SHADOW); | you want *not*
405 f->SetLoadMode(NO_SEQ | NO_SHADOW);| to load from the
406 f->SetLoadMode(NO_SHADOWSEQ); | target file
407 f->SetFileName(fileName);
410 <b>Don't</b> use any longer old deprecated style: <br>
412 gdcm::File *f = new gdcm::File(fileName);</TT> <br>
414 <LI> User is now allowed to tell <TT>gdcm::DicomDir</TT> constructor
415 he doesn't want to deal with <TT>SeqEntry</TT>
416 (every time it's possible, i.e for 'true length' Sequences) <br>
417 and/or he doesn't want to deal with <TT>Shadow groups</TT>
418 (every time it's possible i.e. when element <TT>0x0000</TT>
419 exists for this Group) <br>
420 or he doesn't want to deal with <TT>SeqEntry</TT> that belong to a
421 <TT>Shadow group</TT> (every time it's possible
422 -'true length' Sequence-)<br>
423 when he parses all the Dicom files within a given directory.<br>
426 gdcm::DicomDir *f = new gdcm::DicomDir();
427 f->SetLoadMode(NO_SEQ); | depending on what
428 f->SetLoadMode(NO_SHADOW); | you want *not*
429 f->SetLoadMode(NO_SEQ | NO_SHADOW);| to load from the files
430 f->SetLoadMode(NO_SHADOWSEQ); | within the root directory
431 f->SetDirectoryName(rootDirectoryName);
434 <b>Don't</b> use any longer old deprecated style: <br>
436 gdcm::DicomDir *dcmdir = new gdcm::DicomDir(dirName, true);</TT><br>
442 <LI> No more trouble when the 'endianess' switches within Sequences.
443 <LI> No more trouble with 'no length Sequences' belonging to a
444 <TT>Shadow Group</TT> when they are 'Implicit VR'.
445 <LI> The difference between <TT>MONOCHROME1</TT> (low values = bright,
446 high values = dark) and <TT>MONOCHROME2</TT> (low values = dark,
447 high values = bright) is now taken into account.<br>
448 It's no longer up to the user to change the pixels value
449 <LI> Writing a 'True Dicom' image after reading an <TT>ACR-NEMA</TT> image
450 does not request any longer from the user to build up
451 'manually' the Meta Elements group (<TT>0x0002</TT>)
452 <LI> Old '24 Bits' <TT>ACR-NEMA</TT> are now correctly re-written
453 in <TT>DICOM V3</TT> mode.
454 <LI> Element <TT>0x0000</TT> of <TT>Shadow groups</TT> is always forced to be a
455 <TT>ValEntry</TT> and its <TT>VR</TT> is forced to <TT>UL</TT>
459 <LI> A.P.I. breaking modifications (since previous version : <TT>1.0</TT>)
