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 <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 <TT>MPEG2</TT> encoded files.
41 <LI> Allow user to tell <TT>gdcm::Document</TT> constructor he just wants
42 to load a given list of <TT>DocEntries</TT>
43 (to save CPU time and RAM space)
44 <LI> Allow 'frame by frame' reading (should be helpfull for huge
46 <LI> Allow subvolume selection / frames selection before reading.
47 <LI> Expose Read/Decompression mechanisms to allow user getting
48 information from <tt>DICOMDIR</TT> <br> -or from his own Data Base-
49 and reading his images without parsing
50 the header, one more time.
54 <LI> Allow user to tell the Writer he doesn't want to write down
55 <TT>SeqEntry</TT> (if any)
56 <LI> Allow user to tell the Writer he doesn't want to write down
57 <TT>Shadow groups</TT> (if any)
58 <LI> Allow user to tell the Writer he wants to split a
59 <TT>Multiframe</TT> image into a serie of
60 <TT>Single frame</TT> images.
61 <LI> Allow user to tell the Writer he wants to agregate a
62 Serie of <TT>Single frame</TT> images into a
63 <TT>Multiframe</TT> image.
67 <LI> Full <TT>Icon Image</TT> management (Read and Write)
68 <LI> Full <TT>Overlays</TT> management (Read and Write) <br>
69 both for '<TT>ACR-NEMA</TT> style' (using groups <TT>0x6000</TT>
70 and next) and '<TT>DICOM V3</TT> style' (using Sequences)
72 <LI> <TT>DICOMDIR</TT>
74 <LI> <TT>DICOMDIR</TT> full management (not limited to
75 <TT> PATIENT</TT>/<TT>STUDY</TT>/<TT>SERIE</TT>/<TT>IMAGE</TT>)
76 <LI> Allow user to add an entry (belonging to the file header Dicom
77 entries)to the default entry list, before
78 making a <TT>DICOMDIR</TT> from a root directory
79 <LI> Allow user to add an entry of his owns (for instance an <TT>Icon</TT>
80 to each image, or to each Serie).
85 <LI> An accurate <TT>SerieHelper</TT> <br>
86 Right now <TT>SerieHelper</TT> only works on 'bona fide Series', and
87 breaks on wrongly forged Series.<br>
88 We are still looking for any heuristics...
89 <LI> A <TT>SerieHelper</TT> that would use the <TT>DICOMDIR</TT> (if any)
90 instead of parsing all the files within the Root Directory
94 <LI> 16-bits-LUT full Management
95 <LI> User friendly management of <TT>Rescale Slope</TT> and
96 <TT>Rescale Intercept</TT>.<br>
97 (Well... Maybe it's up to the application to deal with it, not to
99 <LI> Allow manual adjunction / automatic recognition (pfff!...)
100 of the private <TT>Dicom Dictionary</TT>
101 to be used to parse <TT>Shadow groups</TT> against.
102 <LI> User friendly way of anonymizing image when Patient's name is
103 burnt-in within the Pixels :-( <br>
104 --> In many cases, the burnt-in Patient's name, etc
105 are actually stored as 'overlays'.<br>
106 'Normal' reading doesn't load those type of overlays.

124 <LI> <a href= "DocCVS/html.developper/index.html">Developper
129 <LI> To be able to use gdcm1.3.x and ITK, developer is now allowed to
130 choose his own namespace for gdcm at CMake time : see GDCM_NAME_SPACE
132 <LI> JPEG and JPEG2000 compression writting are now available.
133 see Examples/WriteDicomAsJPEG.cxx and Examples/WriteDicomAsJPEG2000.cxx
134 <LI> To <i>try to</i> make gdcm images PACS usable, user is now allowed to
135 gdcm what kind of image he wants to write, using : <br>
136 <TT>void FileHelper::SetContentType (ImageContentType c);</TT> <br>
137 Four different types are identifyed (probabely more will be added) :
140 1) user created ex nihilo his own image and wants to write it as a Dicom image.<br>
141 c : <TT>USER_OWN_IMAGE</TT>
143 2) user modified the pixels of an existing image, using mathematical operations.<br>
144 c : <TT>FILTERED_IMAGE</TT>
146 3) user created a new image, using existing images (eg MIP, MPR, cartography image)<br>
147 c : <TT>CREATED_IMAGE</TT>
149 4) user modified/added some tags *without processing* the pixels (anonymization, etc)<br>
150 c : <TT>UNMODIFIED_PIXELS_IMAGE</TT>
152 <LI> Stupid difference between <TT>gdcm::ValEntry</TT>
153 and <TT>gdcm::BinEntry</TT> removed. <br>
154 Only <TT>gdcm::DataEntry</TT> exist, now.
155 Should have been considered as a 'Bug Fix'.<br>
156 Actually, it's an API breaking modification ...
159 <TT>std::string const &DataEntry::GetString() const</TT><br>
160 returns as a string (when possible) the value of the DataEntry
162 <TT>void DataEntry::SetString(std::string const &value)</TT><br>
163 Sets the 'value' of a DataEntry, passed as a std::string
165 <TT>void DataEntry::SetBinArea( uint8_t *area, bool self ) </TT><br>
166 Sets the value (non string) of the current Dicom DataEntry
168 <TT>void DataEntry::CopyBinArea( uint8_t *area, uint32_t length )</TT><br>
169 Inserts the value (non string) into the current DataEntry
171 <TT>void DataEntry::SetValue(const uint32_t &id, const double
173 Inserts the elementary (non string) value into the current
174 (multivaluated) DataEntry, at the <TT>id></TT> position.
176 <TT>double DataEntry::GetValue(const uint32_t &id) const </TT><br>
177 returns, as a double one of the values (when entry is
178 multivaluated), identified by its index <TT>id</TT>.
181 <TT>DocEntrySet::GetEntryValue()</TT> replaced by
182 <TT>DocEntrySet::GetEntryString()</TT> <br>
183 <LI> SerieHelper : <br>
184 Add some methods, to split a 'SingleSerieUID' Fileset into
185 'Extra Coherent' FileSets. <br>
186 They return a std::map of 'Filesets' (actually : std::vector
188 The key is the 'Orientation', the 'Position'
189 or the value of a user choosen 'Tag' <br>
190 - <TT>XCoherentFileSetmap SplitOnOrientation(FileList *fileSet);
192 - <TT>XCoherentFileSetmap SplitOnPosition(FileList *fileSet);
194 - <TT>XCoherentFileSetmap SplitOnTagValue(FileList *fileSet,
195 uint16_t group, uint16_t element);
197 These methods must be called by user, depending on what he wants
198 to do, at application time.- *he* only knows what his Series
200 <LI> To avoid memory leaks and seg faults the user intended classes
201 use now a Reference Counter.<br>
203 <LI> <TT>new()</TT> and <TT>delete()</TT> are replaced by
204 <TT>New()</TT> and <TT>Delete()</TT>
205 <LI> <TT>Register()</TT> and <TT>Unregister()</TT> methods are
207 <LI> --> Well ... People from ITK don't seem to agree too much with
209 They demand to be allowed to allocate gdcm objects in the stack as
210 well, not only in the heap.
215 <LI> API breaking modifications (since previous version)
217 <LI> Stupid difference between <TT>gdcm::ValEntry</TT>

364 <TT>gdcm::Dict:AddDict(std::string fullPathPrivateDictionaryFileName)</TT>
366 <TT>gdcm::Dict::RemoveDict(std::string fullPathPrivateDictionaryFileName)</TT>
368 to allow user to choose the 'Private Dictionary' he wants to work with.
370 One can dream about a better API;<br>
371 This one allow right now anybody to see very easyly if the use
372 of a given private dicom dictionary is of any help or not.
375 <TT>PrintFile</TT> has now a new command line argument manager option :<br>
376 <TT>dict=fullPathNamePrivateDictionaryFile</TT><br>
377 to allow user to see with no extra coding what differences
378 makes the use or not of a private Dicom Dictionary.<br>
379 e.g. : use it as follow <br>
380 <TT>PrintFile filein=myGEdicomFile.dcm
381 dict=/user/userName/gdcm/Dicts/GEMS-Advance.dic</TT>
384 (Not a great one ...)
385 Stupid method names : <br><TT>DicomDir::WriteDicomDir()</TT>
386 and <TT>DicomDir::AnonymizeDicomDir()</TT> <br>replaced by : <br>
387 <TT>DicomDir::Write()</TT>
388 and <TT>DicomDir::Anonymize()</TT>
391 void Document::AddForceLoadElement(uint16_t group, uint16_t elem);
393 allows user to tell <TT>gdcm::Document</TT> Loader he wants
394 to force the loading of a given set of <TT>DocEntries</TT>,
395 even if their length exceeds the current
396 <TT>MAX_SIZE_LOAD_ELEMENT_VALUE</TT>.
399 Many users expect from <TT>vtkGdcmReader</TT> it 'orders' the images
400 (that's the job of <TT>gdcm::SerieHelper</TT> ...)<br>
401 When user <b>knows</b> the files with same Serie UID
402 have same sizes, same 'pixel' type, same color convention, ...
403 the right way to proceed is as follow :
405 gdcm::SerieHelper *sh= new gdcm::SerieHelper();
406 // if user wants *not* to load some parts of the file headers
407 sh->SetLoadMode(loadMode);
409 // if user wants *not* to load some files
410 sh->AddRestriction(group, element, value, operator);
411 sh->AddRestriction( ...
412 sh->SetDirectory(directoryWithImages);
414 // if user *knows* how to order his files
415 sh->SetUserLessThanFunction(userSuppliedComparisonFunction);
417 // if user wants to sort reverse order
418 sh->SetSortOrderToReverse();
420 // here, we suppose only the first 'Single SerieUID' Fileset is of interest
421 // Just iterate using sh->NextSingleSerieUIDFileSet()
422 // if you want to get all of them
423 gdcm::FileList *l = sh->GetFirstSingleSerieUIDFileSet();
425 // if user is doesn't trust too much the files with same Serie UID
426 if ( !sh->IsCoherent(l) )
427 return; // not same sizes, or not same 'pixel type' -> stop
429 sh->OrderFileList(l); // sort the list
431 vtkGdcmReader *reader = vtkGdcmReader::New();
432 // if user wants to modify pixel order (Mirror, TopDown, ...)
433 // he has to supply the function that does the job
434 // (a *very* simple example is given in vtkgdcmSerieViewer.cxx)
435 reader->SetUserFunction (userSuppliedFunction);
437 // to pass a 'Single SerieUID' Fileset as produced by gdcm::SerieHelper
438 reader->SetCoherentFileList(l);

445 <TT>vtkgdcmSerieViewer dirname=Dentist reverse</TT><br>

450 <LI> <TT>vtkGdcmReader::SetUserFunction (userSuppliedFunction)</TT><br>
452 <TT>void userSuppliedFunction(uint8_t *imageData, File *f);</TT><br>
453 allows user to reorganize the pixels of each image just after reading
454 it (to mirror, or topdown the image, for instance)<br>
455 Note : <TT>uint8_t *</TT> doesn't mean it works only on 8 Bits images.
456 <br> It's for prototyping. Feel free to cast it.
459 SerieHelper::SetUserLessThanFunction(userSuppliedComparisonFunction)
460 </TT><br> with : <br>
461 <TT>bool userSuppliedComparisonFunction(File *, File *);</TT><br>
462 allows user -when he knows more about his files than gdcm does-
463 to give his own comparison function.
464 <LI> <TT>SerieHelper::SetSortOrderToReverse</TT> allows user to ask
465 to sort the Files reverse order.
466 <LI> <TT>SerieHelper::AddRestriction</TT> has now a new constructor<br>
467 <TT>AddRestriction(group, element, value, operator);</TT><br>
468 allows user to exclude some files from the sorting, according to
469 any comparison operator <br>
470 (<TT>GDCM_EQUAL</TT>, <TT>GDCM_DIFFERENT</TT>,
471 <TT>GDCM_GREATER</TT>, <TT>GDCM_GREATEROREQUAL</TT>,

475 <LI> <TT>AnonymizeNoLoad</TT> used with <TT>dirin=inputDirectoryName</TT>
476 anonymizes all the files within the given Directory.
478 User may also choose extra elements he wants to rub out: <br>
479 <TT>rubout=listOfElementsToRubOut</TT><br>
480 with <tt>listOfElementsToRubOut : group1-elem1,group2-elem2,
481 ...</TT> (in hexa, no space within the list )
483 <LI> <TT>gdcm::SerieHelper()</TT> has a new method
484 <TT>void AddGdcmFile(File *header)</TT>, that allows aware user to
485 create a '<TT>FileList</TT>' (actually a
486 <TT>std::vector< File* > </TT>).<br>
487 The <TT>FileList</TT> created this way will be the
488 'first one' in the <TT>gdcm::FileHelper()</TT> (retrieve it with
489 <TT>FileList *GetFirstCoherentFileList()</TT> ).<br>
490 It may be sorted using <TT>OrderFileList</TT>.<br>
491 No 'coherence check' will be performed on this <TT>FileList</TT>
493 It may be passed to a <TT>vtkGdcmReader</TT>
494 (to avoid parsing twice the files)
496 <LI> <TT>vtkGdcmReader</TT> can now get the result of
497 <TT>gdcm::SerieHelper</TT> (to avoid parsing twice the files)<br>
498 Proceed as follow :<br>
500 gdcmSerieHelper *sh = new gdcmSerieHelper();
501 sh->SetDirectory(myImageDirectory, true);
502 gdcmFileList *l = s->GetFirstCoherentFileList();
505 vtkGdcmReader *gr = new vtkGdcmReader();
506 gr->SetCoherentFileList(l);
509 This works with a directory that contains only one '<TT>Serie</TT>'
510 (same <TT>Serie UID</TT> for all the images).<br>
511 If it contains more than one <TT>Serie</TT>, you'll have to loop
512 on the Series, using <TT>GetNextCoherentFileList()</TT>;<br>
513 It will be up to the user to delete the <TT>gdcm::File</TT>.
515 See <TT>vtkgdcmSerieViewer</TT> for an example.
517 <LI> Both <TT>vtkgdcmViewer</TT> and <TT>vtkgdcmViewer2</TT>
518 are available to allow easy displaying of single/multiframe
519 GreyLevel/RGB/PaletteColor images<br><br>
520 <LI> <TT>DICOMDIR</TT> anonymiser (<TT>Load</TT> and <TT>Noload</TT> mode)
522 <LI> Because the <TT>gdcm::DicomDir::Load()</TT> method may be used
523 either for loading an already made <TT>DICOMDIR</TT> file or for
524 parsing all the dicom files with a given root directory we
525 syntaxically separated the operations: <br>
526 For loading an already made <TT>DICOMDIR</TT> file, use : <br>
528 gdcm::DicomDir *d = new gdcm::DicomDir();
529 d->SetFileName(fileName);
533 For parsing all the dicom files within a given root directory, use :<br>
535 gdcm::DicomDir *d = new gdcm::DicomDir();
536 d->SetDirectoryName(dirName);
540 <b>Don't</b> use any longer old deprecated style: <br>
542 gdcm::DicomDir *d = new gdcm::DicomDir();<br>
543 d->SetParseDir(true); // </TT>or <TT>d->SetParseDir(false);<br>
544 d->Load( fileName );<br>

598 <LI> No more trouble when the 'endianess' switches within Sequences.
599 <LI> No more trouble with 'no length Sequences' belonging to a
600 <TT>Shadow Group</TT> when they are 'Implicit VR'.
601 <LI> The difference between <TT>MONOCHROME1</TT> (low values = bright,
602 high values = dark) and <TT>MONOCHROME2</TT> (low values = dark,
603 high values = bright) is now taken into account.<br>
604 It's no longer up to the user to change the pixels value
605 <LI> Writing a 'True Dicom' image after reading an <TT>ACR-NEMA</TT> image
606 does not request any longer from the user to build up
607 'manually' the Meta Elements group (<TT>0x0002</TT>)
608 <LI> Old '24 Bits' <TT>ACR-NEMA</TT> are now correctly re-written
609 in <TT>DICOM V3</TT> mode.
610 <LI> Element <TT>0x0000</TT> of <TT>Shadow groups</TT> is always forced to be a
611 <TT>ValEntry</TT> and its <TT>VR</TT> is forced to <TT>UL</TT>
615 <LI> A.P.I. breaking modifications (since previous version : <TT>1.0</TT>)

710 <LI> The new <TT>gdcmDocument</TT> class is a parent class of
711 <TT>gdcmHeader</TT> class and <TT>gdcmDicomDir</TT> class.
712 <LI> Massive modifications in the Class Diagram :
714 <LI> any dicom related file is a <TT>gdcmDocument</TT>
715 <LI> a <TT>gdcmDocument</TT> can be :
717 <LI> a <TT>gdcmHeader</TT>, if it contains pixel data
718 <LI> a <TT>gdcmDicomDir</TT>, if it contains only informations

722 <LI> a <TT>gdcmDocument</TT> is_a <TT>gdcmElementSet</TT>,
723 composed of a set of <TT>gdcmEntry</TT> separated into :

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

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

755 compressed Dicom files might be working (check-it out).
756 <LI> And also, fewer memory leaks, cleaned-up stl usage (should work
757 with gcc-3.x), python disutil installer (see file setup.py)
758 supporting both Swig and vtk wrapping.
