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>.<br>
107 (Well... Maybe it's up to the application to deal with it, not to
109 <LI> Allow manual adjunction / automatic recognition (pfff!...)
110 of the private <TT>Dicom Dictionary</TT>
111 to be used to parse <TT>Shadow groups</TT> against.
112 <LI> User friendly way of anonymizing image when Patient's name is
113 carved in the Pixels :-(

131 <LI> <a href= "DocCVS/html.developper/index.html">Developper
135 <LI> To <i>try to</i> make gdcm images PACS usable, user is now allowed to
136 gdcm what kind of image he wants to write, using : <br>
137 <TT>void FileHelper::SetContentType (ImageContentType c);</TT> <br>
138 Four different types are identify (probabely more will be added) :
141 1) user created ex nihilo his own image and wants to write it as a Dicom image.<br>
142 c : <TT>USER_OWN_IMAGE</TT>
144 2) user modified the pixels of an existing image, using mathematical operations.<br>
145 c : <TT>FILTERED_IMAGE</TT>
147 3) user created a new image, using existing images (eg MIP, MPR, cartography image)<br>
148 c : <TT>CREATED_IMAGE</TT>
150 4) user modified/added some tags *without processing* the pixels (anonymization, etc)<br>
151 c : <TT>UNMODIFIED_PIXELS_IMAGE</TT>
153 <LI> Stupid difference between <TT>gdcm::ValEntry</TT>
154 and <TT>gdcm::BinEntry</TT> removed. <br>
155 Only <TT>gdcm::DataEntry</TT> exist, now.
156 Should have been considered as a 'Bug Fix'.<br>
157 Actually, it's an API breaking modification ...
160 <TT>std::string const &DataEntry::GetString() const</TT><br>
161 returns as a string (when possible) the value of the DataEntry
163 <TT>void DataEntry::SetString(std::string const &value)</TT><br>
164 Sets the 'value' of a DataEntry, passed as a std::string
166 <TT>void DataEntry::SetBinArea( uint8_t *area, bool self ) </TT><br>
167 Sets the value (non string) of the current Dicom DataEntry
169 <TT>void DataEntry::CopyBinArea( uint8_t *area, uint32_t length )</TT><br>
170 Inserts the value (non string) into the current DataEntry
172 <TT>void DataEntry::SetValue(const uint32_t &id, const double
174 Inserts the elementary (non string) value into the current
175 (multivaluated) DataEntry, at the <TT>id></TT> position.
177 <TT>double DataEntry::GetValue(const uint32_t &id) const </TT><br>
178 returns, as a double one of the values (when entry is
179 multivaluated), identified by its index <TT>id</TT>.
182 <TT>DocEntrySet::GetEntryValue()</TT> replaced by
183 <TT>DocEntrySet::GetEntryString()</TT> <br>
184 <LI> SerieHelper : <br>
185 Add some methods, to split a 'SingleSerieUID' Fileset into
186 'Extra Coherent' FileSets. <br>
187 They return a std::map of 'Filesets' (actually : std::vector
189 The key is the 'Orientation', the 'Position'
190 or the value of a user choosen 'Tag' <br>
191 - <TT>XCoherentFileSetmap SplitOnOrientation(FileList *fileSet);
193 - <TT>XCoherentFileSetmap SplitOnPosition(FileList *fileSet);
195 - <TT>XCoherentFileSetmap SplitOnTagValue(FileList *fileSet,
196 uint16_t group, uint16_t element);
198 These methods must be called by user, depending on what he wants
199 to do, at application time.- *he* only knows what his Series
201 <LI> To avoid memory leaks and seg faults the user intended classes
202 use now a Reference Counter.<br>
204 <LI> <TT>new()</TT> and <TT>delete()</TT> are replaced by
205 <TT>New()</TT> and <TT>Delete()</TT>
206 <LI> <TT>Register()</TT> and <TT>Unregister()</TT> methods are
208 <LI> --> Well ... People from ITK don't seem to agree too much with
210 They demand to be allowed to allocate gdcm objects in the stack as
211 well, not only in the heap.
216 <LI> API breaking modifications (since previous version)
218 <LI> Stupid difference between <TT>gdcm::ValEntry</TT>

295 <LI> Implicit VR - Big Endian (G.E Private) Transfert Syntax 16 Bits
296 images are now read correctly.
297 <LI> File::GetZOrigin() returns accurate result in any case.
304 <LI> Use of <TT>Implicit Value Representation</TT> writting mode may
305 causes troubles, when there are some <TT>SQ</TT> belonging to a
306 <TT>Shadow Group</TT>. <br>
307 Better you use <TT>Explicit Value Representation</TT> writting mode ...
308 <LI> Troubles on 'Big endian' processors (i.e. Apple/Motorola, SunSparc

339 <TT>gdcm::Dict:AddDict(std::string fullPathPrivateDictionaryFileName)</TT>
341 <TT>gdcm::Dict::RemoveDict(std::string fullPathPrivateDictionaryFileName)</TT>
343 to allow user to choose the 'Private Dictionary' he wants to work with.
345 One can dream about a better API;<br>
346 This one allow right now anybody to see very easyly if the use
347 of a given private dicom dictionary is of any help or not.
350 <TT>PrintFile</TT> has now a new command line argument manager option :<br>
351 <TT>dict=fullPathNamePrivateDictionaryFile</TT><br>
352 to allow user to see with no extra coding what differences
353 makes the use or not of a private Dicom Dictionary.<br>
354 e.g. : use it as follow <br>
355 <TT>PrintFile filein=myGEdicomFile.dcm
356 dict=/user/userName/gdcm/Dicts/GEMS-Advance.dic</TT>
359 (Not a great one ...)
360 Stupid method names : <br><TT>DicomDir::WriteDicomDir()</TT>
361 and <TT>DicomDir::AnonymizeDicomDir()</TT> <br>replaced by : <br>
362 <TT>DicomDir::Write()</TT>
363 and <TT>DicomDir::Anonymize()</TT>
366 void Document::AddForceLoadElement(uint16_t group, uint16_t elem);
368 allows user to tell <TT>gdcm::Document</TT> Loader he wants
369 to force the loading of a given set of <TT>DocEntries</TT>,
370 even if their length exceeds the current
371 <TT>MAX_SIZE_LOAD_ELEMENT_VALUE</TT>.
374 Many users expect from <TT>vtkGdcmReader</TT> it 'orders' the images
375 (that's the job of <TT>gdcm::SerieHelper</TT> ...)<br>
376 When user <b>knows</b> the files with same Serie UID
377 have same sizes, same 'pixel' type, same color convention, ...
378 the right way to proceed is as follow :
380 gdcm::SerieHelper *sh= new gdcm::SerieHelper();
381 // if user wants *not* to load some parts of the file headers
382 sh->SetLoadMode(loadMode);
384 // if user wants *not* to load some files
385 sh->AddRestriction(group, element, value, operator);
386 sh->AddRestriction( ...
387 sh->SetDirectory(directoryWithImages);
389 // if user *knows* how to order his files
390 sh->SetUserLessThanFunction(userSuppliedComparisonFunction);
392 // if user wants to sort reverse order
393 sh->SetSortOrderToReverse();
395 // here, we suppose only the first 'Single SerieUID' Fileset is of interest
396 // Just iterate using sh->NextSingleSerieUIDFileSet()
397 // if you want to get all of them
398 gdcm::FileList *l = sh->GetFirstSingleSerieUIDFileSet();
400 // if user is doesn't trust too much the files with same Serie UID
401 if ( !sh->IsCoherent(l) )
402 return; // not same sizes, or not same 'pixel type' -> stop
404 sh->OrderFileList(l); // sort the list
406 vtkGdcmReader *reader = vtkGdcmReader::New();
407 // if user wants to modify pixel order (Mirror, TopDown, ...)
408 // he has to supply the function that does the job
409 // (a *very* simple example is given in vtkgdcmSerieViewer.cxx)
410 reader->SetUserFunction (userSuppliedFunction);
412 // to pass a 'Single SerieUID' Fileset as produced by gdcm::SerieHelper
413 reader->SetCoherentFileList(l);
416 You can see a full example in <TT>vtk/vtkgdcmSerieViewer.cxx</TT><br>
419 <TT>vtkgdcmSerieViewer dirname=Dentist mirror</TT><br>
420 <TT>vtkgdcmSerieViewer dirname=Dentist reverse</TT><br>
421 <TT>vtkgdcmSerieViewer dirname=Dentist reverse topdown</TT><br>
425 <LI> <TT>vtkGdcmReader::SetUserFunction (userSuppliedFunction)</TT><br>
427 <TT>void userSuppliedFunction(uint8_t *imageData, File *f);</TT><br>
428 allows user to reorganize the pixels of each image just after reading
429 it (to mirror, or topdown the image, for instance)<br>
430 Note : <TT>uint8_t *</TT> doesn't mean it works only on 8 Bits images.
431 <br> It's for prototyping. Feel free to cast it.
434 SerieHelper::SetUserLessThanFunction(userSuppliedComparisonFunction)
435 </TT><br> with : <br>
436 <TT>bool userSuppliedComparisonFunction(File *, File *);</TT><br>
437 allows user -when he knows more about his files than gdcm does-
438 to give his own comparison function.
439 <LI> <TT>SerieHelper::SetSortOrderToReverse</TT> allows user to ask
440 to sort the Files reverse order.
441 <LI> <TT>SerieHelper::AddRestriction</TT> has now a new constructor<br>
442 <TT>AddRestriction(group, element, value, operator);</TT><br>
443 allows user to exclude some files from the sorting, according to
444 any comparison operator <br>
445 (<TT>GDCM_EQUAL</TT>, <TT>GDCM_DIFFERENT</TT>,
446 <TT>GDCM_GREATER</TT>, <TT>GDCM_GREATEROREQUAL</TT>,
447 <TT>GDCM_LESS</TT>, <TT>GDCM_LESSOREQUAL</TT>), not only on the
450 <LI> <TT>AnonymizeNoLoad</TT> used with <TT>dirin=inputDirectoryName</TT>
451 anonymizes all the files within the given Directory.
453 User may also choose extra elements he wants to rub out: <br>
454 <TT>rubout=listOfElementsToRubOut</TT><br>
455 with <tt>listOfElementsToRubOut : group1-elem1,group2-elem2,
456 ...</TT> (in hexa, no space within the list )
458 <LI> <TT>gdcm::SerieHelper()</TT> has a new method
459 <TT>void AddGdcmFile(File *header)</TT>, that allows aware user to
460 create a '<TT>FileList</TT>' (actually a
461 <TT>std::vector< File* > </TT>).<br>
462 The <TT>FileList</TT> created this way will be the
463 'first one' in the <TT>gdcm::FileHelper()</TT> (retrieve it with
464 <TT>FileList *GetFirstCoherentFileList()</TT> ).<br>
465 It may be sorted using <TT>OrderFileList</TT>.<br>
466 No 'coherence check' will be performed on this <TT>FileList</TT>
468 It may be passed to a <TT>vtkGdcmReader</TT>
469 (to avoid parsing twice the files)
471 <LI> <TT>vtkGdcmReader</TT> can now get the result of
472 <TT>gdcm::SerieHelper</TT> (to avoid parsing twice the files)<br>
473 Proceed as follow :<br>
475 gdcmSerieHelper *sh = new gdcmSerieHelper();
476 sh->SetDirectory(myImageDirectory, true);
477 gdcmFileList *l = s->GetFirstCoherentFileList();
480 vtkGdcmReader *gr = new vtkGdcmReader();
481 gr->SetCoherentFileList(l);
484 This works with a directory that contains only one '<TT>Serie</TT>'
485 (same <TT>Serie UID</TT> for all the images).<br>
486 If it contains more than one <TT>Serie</TT>, you'll have to loop
487 on the Series, using <TT>GetNextCoherentFileList()</TT>;<br>
488 It will be up to the user to delete the <TT>gdcm::File</TT>.
490 See <TT>vtkgdcmSerieViewer</TT> for an example.
492 <LI> Both <TT>vtkgdcmViewer</TT> and <TT>vtkgdcmViewer2</TT>
493 are available to allow easy displaying of single/multiframe
494 GreyLevel/RGB/PaletteColor images<br><br>
495 <LI> <TT>DICOMDIR</TT> anonymiser (<TT>Load</TT> and <TT>Noload</TT> mode)
497 <LI> Because the <TT>gdcm::DicomDir::Load()</TT> method may be used
498 either for loading an already made <TT>DICOMDIR</TT> file or for
499 parsing all the dicom files with a given root directory we
500 syntaxically separated the operations: <br>
501 For loading an already made <TT>DICOMDIR</TT> file, use : <br>
503 gdcm::DicomDir *d = new gdcm::DicomDir();
504 d->SetFileName(fileName);
508 For parsing all the dicom files within a given root directory, use :<br>
510 gdcm::DicomDir *d = new gdcm::DicomDir();
511 d->SetDirectoryName(dirName);
515 <b>Don't</b> use any longer old deprecated style: <br>

518 d->SetParseDir(true); // </TT>or <TT>d->SetParseDir(false);<br>
519 d->Load( fileName );<br>

685 <LI> The new <TT>gdcmDocument</TT> class is a parent class of
686 <TT>gdcmHeader</TT> class and <TT>gdcmDicomDir</TT> class.
687 <LI> Massive modifications in the Class Diagram :
689 <LI> any dicom related file is a <TT>gdcmDocument</TT>
690 <LI> a <TT>gdcmDocument</TT> can be :
692 <LI> a <TT>gdcmHeader</TT>, if it contains pixel data
693 <LI> a <TT>gdcmDicomDir</TT>, if it contains only informations

703 <TT>gdcmBinEntry</TT>
704 <LI> <TT>gdcmSeqEntry</TT> (VR = <TT>SQ</TT>, i.e Dicom Sequences)<br>
705 they are dealt as tree-like structures :<br>
706 - a <TT>gdcmSeqEntry</TT> is considered as a set

712 <LI> Improvement of the jpeg sub-library: jpeg
713 compressed Dicom files (lossless and lossy)
714 might be read (check-it out)

730 compressed Dicom files might be working (check-it out).
731 <LI> And also, fewer memory leaks, cleaned-up stl usage (should work
732 with gcc-3.x), python disutil installer (see file setup.py)
733 supporting both Swig and vtk wrapping.
734 <LI> Introduction of a RLE (Run-Time Encoding) library
735 <LI> Color images (RGB or Palette Color) are dealt with
736 <LI> Confusing names <TT>gdcmPatient</TT>, <TT>gdcmStudy</TT>,
737 <TT>gdcmSerie</TT>, <TT>gdcmPatient</TT> changed to
