14 Description: Rewrite gdcmDebug so that it works
19 ----------------------------------------------------------------------------
20 Description: Need to fix cygwin + wrong path (passing UNIX path when windows patch expected)
25 ----------------------------------------------------------------------------
26 Description: Need a test for gdcmHeaderHelper (iterating over gdcmData) for instance
30 Comments: It used to seg fault when a README file was found
31 ----------------------------------------------------------------------------
32 Description: gdcmJpeg8 is strictly a copy/paste of gdcmJpeg12.cxx.
36 We should write the code in a common place, then include this 'cxx' file so
37 the define from gdcm_mangle redefine to the proper one.
39 This will be usefull since I may need in the future a 16bits version of this
41 -----------------------------------------------------------------------------
42 Description: Change jpeg 'exit' call to standard c++ exception using the jpeg
49 -----------------------------------------------------------------------------
50 Description: Add kwsys as a subdir somewhere in gdcm
55 -----------------------------------------------------------------------------
60 Comments: ljpeg was rip from medcon and not the official one. medcon tried to
61 optimised function using MACRO (doh!), so it make its very unreadable and very
62 hard to fix warnings. Should go back to official source, copy proper copyright
63 and fix warnings on dashboard
64 13/10: update apparently no dicom toolkit use this lib as it is too buggy.
65 We should use the ls-patch for ijg instead. Thus we can safely get rid of that
67 14/10: PHILIPS_Gyroscan-12-MONO2-Jpeg_Lossless.dcm prove that I was right the
68 old Cornwell lib is buggy and does not read anything.
69 -----------------------------------------------------------------------------
70 Description: Extent reading support
74 Comments: All ITK/VTK readers support selecting extent. gdcm should support
75 selecting extent before being inserted into ITK
76 -----------------------------------------------------------------------------
77 Description: Generate new UID each time we write DICOM
81 Comments: According to DICOM ref a new UID should be created each we write a
82 DICOM images. I guess it should be an option so that we can still use md5sum to
83 check dicom file. The proposed way was:

86 Bah, comme Win32 pose encore pb:
88 0000000 147 144 143 155 012
90 radical + 147.144.143.155 + IP + time()
92 -----------------------------------------------------------------------------
93 Description: gdcmDicomDir and SQItem creation
96 Details: DicomDir creates some SQItem (by new). After that, it creates
97 the corresponding DicomDirPatient, etc. using the content of the SQItem
98 (the content is composed with some DocEntry's that can't be destroyed).
99 So, if the SQItem is deleted, then it's content is deleted to. But the
100 DicomDirPatient, etc. use the content of the SQItem. Then, the SQItem can't
101 be deleted, and when have memory leaks
103 -----------------------------------------------------------------------------
104 Description: [BUG] Better handling of unfound Dicom dictionary.
105 When gdcm doesn't find the Dicom dictionary (because it's
106 path to the directory of dictionary is uncorrect, either
107 because the install relative layout was broken after file moves
108 or because the environnement variable GDCM_DICT_PATH is
109 unpropely set), gdcm will:
111 2/ throw an exception (that is internaly UNcatched by gdcm)
112 that in most cases provoques the caller application to
113 exit uncleanly (uncatched excpetions in fine call abort() ).
114 Additionaly on Win32 the warning print isn't displayed because
115 exiting occurs prior to cerr or cout is flushed properly.
118 Details: fixes (from dirty to clean)
119 1/ force Win32 to flush it's buffer so at least the user gets some
120 reason why it's application exited (when called in command
121 environement). Note: it looks like the "cerr << flush" fails. Sigh.
122 2/ within gdcm catch the exception, display a decent warning, and
124 3/ see the comment below on how to enhance the API and fix things
126 Comments: ENH proposal:
127 The caller migth not be aware of the path to the dictionaries
128 on invocation of gdcm (think this path is set by the Interface
129 because the caller wants to skip the default gdcm dictionary in order
130 to provide his own ones e.g. another language based one).
131 Hence, gdcm should postpone the parsing of the default dictionary
132 instead of doing it on library entry.
133 This would enable two things:
134 - It would give a chance to the caller to set the path to
135 the dictionaries he whishes to use, through a call to
136 newly created DictSet::SetDictionaryPath( string ).
137 - It would avoid the burden of using the GDCM_DICT_PATH
138 environnement variable and enable GDCM CONTROL FROM WITHIN
139 THE API. Optionaly, if the caller didn't use the API to
140 provide his prefered path, gdcm could still default to
142 -----------------------------------------------------------------------------
143 Description: vtk/vtkGdcmReader doesn't positionate the normal to the image
146 Details: vtkGdcmReader::CheckFileCoherence() sets the DataOrigin[i]
147 but doesn't set the plane (image seen in 3D) normal (is it
148 possible any how). This plane normal could be extracted from
149 the "orientation" info of the gdcmHeader ( refer to
150 grep "Orientation" Dicts/dicomV3.dic).
151 Problem exhibiting this defect: cine loop on a pile of images
152 whose Origin is correct, but whose normal is not set will
155 * vtkGdcmReader inherits from vtkImageReader which aggregates
156 a vtkTranform. vtkGdcmReader could store (when the user requires
157 it, see below) the origin/normal taken from the Dicom Header
158 within this vtkTransform (looks like a natural place to store
159 this spacial information).
160 * Both settings of the origin and/OR the normal of the plane (image)
161 should be an option defined with a flag (On/Off) in the
163 -----------------------------------------------------------------------------
164 Description: Fix the Python wrappers
169 -----------------------------------------------------------------------------
170 Description: clean up gdcmFile/gdcmHeader relationship
174 * simplify the API for the user (no need to call GetImageData() before
176 * avoid memory leaks with with Pixel_Data.
178 -----------------------------------------------------------------------------
179 Description: remove all autotools references
184 -----------------------------------------------------------------------------
185 Description: introduce namespace "gdcm"
190 1/ Problem: using enum with name like 'Unknow' on .Net, or LP on cygwin
192 2/ Question: when introducing the namespace, should we remove the gdcm
193 prefix from classes or keep it ?
194 -----------------------------------------------------------------------------
195 Description: complete the doxygen Documentation
200 -----------------------------------------------------------------------------
201 Description: test the private dictionary part.
206 * Frog: where can we obtain such a private/dictionary and the corresponding
207 Dicom file ? Any examples on-line ?
208 -----------------------------------------------------------------------------
209 Description: fix definitively the memory leaks problems.
213 Comments: There is a nightly dashboard that run valgrind every night
214 (zorglub | GDCM-Linux-g++)
215 -----------------------------------------------------------------------------
216 Description: test gdcm on a big endian OS.
220 Comments: There is a nightly dashboard that run on MacOSX each nite
221 (midworld.kitwarein | GDCM-DarwinG5-g++ )
222 -----------------------------------------------------------------------------
223 Description: More tests !
227 * an example of new test could be to clone a Dicom image by
228 copying gdcmDocEntry one after the other
230 * look at traversal used in Example/FlatHashTablePrint.cxx
231 -----------------------------------------------------------------------------
232 Description: revoir la gestion des resources, win32 permet d'inclure des
233 fichiers texte (=dicomV3.dic) dans une dll ou quelquechose du genre.
238 * Frog: no comprendo !? De plus est-ce portable ?
239 * To improve load time it could be usefull to have the dictionary directly in
240 'c++' code or in a more binary format.
241 * This will also solve some issues where /dummy/ user did nor set
242 GDCM_DICT_PATH properly neither 'make install'
243 -----------------------------------------------------------------------------
244 Description: Convert the C-like IO to C++ IO:
248 remove all the C-oriented IO references like FILE*, fread...
249 and replace them with the C++ fstream notation.
250 Provide overload of operators << and >> for any gdcm class using file IO.
252 * Question: the underlying jpeg libraries (written in C) use the FILE*
253 notation. Is there a way to still use fstream in gdcm, and
254 build or pass the proper FILE* to jpeg libs ?
255 * Binary IO references are available at
256 http://www.angelfire.com/country/aldev0/cpphowto/cpp_BinaryFileIO.html
257 * The internal API should be rewritten so that gdcm speaking to jpeg lib is
258 done with stream/string and not directly opened FILE*
259 * No stdio.h anymore anywhere tolerated !
260 -----------------------------------------------------------------------------
261 Description: generate methods based on VM.
265 * cmake should parse le DICOM dictionary to generate methods like
266 gdcm???::SetImagePosition(int, int)
268 //generated content do not edit
271 gdcm???::SetImageNumber(int)
273 //generated content do not edit
277 * Regrain: a dicom dictionary entry name is NOT UNIQUE [this means
278 two tags=(group, element) can share the same name].
279 What should the wrapper do in such a case !?
280 * Frog: what does VM stand for ?
281 * VM = Value Multiplicity
282 -----------------------------------------------------------------------------
283 Description: Add information on supported imagers (constructor/model)
286 Details: in order to promote gdcm make a list (on the web pages)
287 of images successfully parsed based on a constructor/model ordering
288 Comments: * frog: gdcmData only lists pathological images. How to collect
289 the ones gdcm works smoothly with (hopefully gdcmData is a small
290 subset of what we would like).
291 -----------------------------------------------------------------------------
292 Description: Add a GetVersion() global function.
295 Details: This is to be used for version assertion with gdcmPython
297 -----------------------------------------------------------------------------
298 -----------------------------------------------------------------------------
299 * vtk/vtkGdcmHeader.cxx: if speed becomes a concern some changes can
300 be made at the cost of memory consumption (refer to header of
301 vtk/vtkGdcmHeader.cxx)
302 -----------------------------------------------------------------------------
303 * gdcmElValSet::SetElValueLengthByNumber IMNSHO should be trashed.
304 It's only purpose is a onliner substitute to calling GetElValueByNumber
305 and then SetLength. This only obfuscates the caller code more than
307 Besides the definition of gdcmElValSet::SetElValueLengthByNumber itself
308 it quite poor since it is a almost exact copy of
309 gdcmElValSet::GetElValueByNumber except for the returned code.
310 gdcmHeader::SetPubElValLengthByNumber (which is based on
311 gdcmElValSet::SetElValueLengthByNumber) is used nowhere...
312 -----------------------------------------------------------------------------
313 * Fix the bug in Test/bug1.cxx (see first comment line): Win32 only.
314 -----------------------------------------------------------------------------
315 * All (or at least many of) the methods of gdcmHeader whose only arguments
316 are an ElValue* (e.g. FindLength, FindVR, LoadElementValue...) can
317 be moved away to ElValue class on condition of transmitting the
318 gdcmHeader.fp attribute. This change should be considered since it
319 would allow those method to avoid artificial calls to ElValue::GetElement(),
321 -----------------------------------------------------------------------------
322 * Eat leading_trailing_whitespace (found in python/gdcmPython/gdcmi) should
323 be used when parsing the dictionary in C++ !
324 -----------------------------------------------------------------------------
325 * Group length is not a unique tag in a file. Hence avoid putting it
326 in the element values dictionary without doing something smarter
327 (say, instead of storing the length store the group and the length
328 so we can related a length to a group).
329 -----------------------------------------------------------------------------
330 * GetPubElValByNumber doit faire la difference entre chaine vide
331 et chaine pas touve''. Eventuellement raiser une exception ?
332 -----------------------------------------------------------------------------
333 * gdcmHeader::LoadElements only loads the element whose length is
334 below the specified size. When accessing the value of such an element
335 the content is unfound ! Find a decent way of loading the value on
337 -----------------------------------------------------------------------------
338 * JPR: fournir une method qui ne fait que lire les elements passes en arguments
339 sous forme d'une liste.
340 -----------------------------------------------------------------------------
341 * JPR: gdcmHeader::CheckSwap() dans le cas ACR pas propre, degager tout de
342 suite si on a deduit que c'en est pas...
343 -----------------------------------------------------------------------------
344 * python /usr/lib/python2.2/site-packages/DaVaW/demo/dvwDcmReader.py
345 and load image /home/frog/cvs/DCMlib/Data/CT-MONO2-16-ankle.dcm
346 will yield wrong coloring scheme as opposed to
347 affim filein=/home/frog/cvs/DCMlib/Data/CT-MONO2-16-ankle.dcm
348 -----------------------------------------------------------------------------
349 * gdcmFile should implement the following API:
351 WriteDicom.SetFileName("MyDicomFile.dcm");
352 string * AllTags = gdcmHeader.GetDcmTagNames();
353 WriteDicom.SetDcmTag(AllTags[5], "253");
354 WriteDicom.SetDcmTag("Patient Name", "bozo");
355 WriteDicom.SetDcmTag("Patient Name", "bozo");
356 WriteDicom.SetImageData(Image);
359 Anonymize(ostream& output) {
360 a = gdcmFile("toto1");
361 a.SetPubValueByName("Patient Name", "");
362 a.SetPubValueByName("Date", "");
363 a.SetPubValueByName("Study Date", "");
