1 2002-12-16 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
2 * src/gdcm.h, src/gdcmHeader.cxx: added GetPubTagNames() resp.
3 GetPubTagNamesByCategory() to gdcmHeader that return a list of the
4 entries within the associated public Dicom dictionary resp. the same
5 information but sorted by the fourth field (PAT, IMG, DIR) of the
7 - Dicts/dicomV3.dic Entries which had and unspecified fourth field
8 are now in the "???" group.
9 - python/gdcm.i changed accordingly,
10 - python/demo/printGroupedPublicDict.py added, that gives an example
11 of the above new functionalities in Python.
13 2002-12-11 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
14 * src/gdcm.h, gdcmHeader.cxx:
15 - historic references to glib's g_malloc and g_free (#defined)
16 were definitively removed.
17 - gdcm.h: cosmetic changes (part of comments moved to Doc/requirements)
18 * src/gdcmElValSet.cxx:
19 - GetElement(guint32, guint32) renamed to GetElementByNumber.
20 - GetElValue(guint32, guint32) renamed to GetElValueByNumber.
21 - GetElValue(string) renamed to GetElValueByName.
22 - Added GetElementByName(string).
23 * src/gdcmHeader.cxx: added
24 - GetPubElValRepByNumber(guint16, guint16)
25 - GetPubElValRepByName(string)
26 - GetShaElValRepByNumber(guint16, guint16)
27 - GetShaElValRepByName(string)
28 - GetShaElValByNumber(guint16, guint16)
29 - GetShaElValRepByName(string)
30 - GetElValRepByNumber(guint16, guint16)
31 - GetElValRepByName(string)
32 - GetElValByNumber(guint16, guint16)
33 - GetElValRepByName(string)
34 * Doc/requirements.txt added.
36 2002-12-9 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
37 * Test/Makefile building now depends on the one of libgdcm.so
38 * src/gdcmHeader.cxx and gdcm.h are now OB (undefined length encoded
39 pixel data) aware which enables finding the address (offset) of
40 the pixel data of JPEG encoded DICOM files. This leaves only a single
41 file in the testSuite whose pixel data address (offset) is unknown.
42 * python/testSuite.py changed accordingly.
44 2002-12-6 Christophe Odet + Hugues Benoit-Cattin + Eric.Boix
45 * VC++ has some strong limitations when working with the STL, as stated
46 in http://support.microsoft.com/support/kb/articles/Q168/9/58.ASP :
47 "Also note that some STL containers (map, set, queue, list, deque)
48 cannot be exported. [...]
49 Some STL classes contain nested classes. These classes can not
51 This is caused by a designed limitation that once a template
52 class is instantiated, it can not be re-instantiated and
54 Since our usage of map<> is ubiquitous in gdcm, this "designed
55 limitation" of VC++ is a pitfall.
56 Hence the Python wrappers of gdcm cannot be incrementally linked
57 against the c++ dynamic library. The dirty but only workaround is
58 to forget about incremental link of dynamic libraries and to generate
59 the Python wrappers library with the inclusions of the underlying C++
61 The following modifications concern this matter on Win32/VC++:
62 - wrapping python correct with standalone wrapped dll (don't use separate
63 dll under windows !!!!)
64 - python21_d debug mode enabled (ask Frog how to use it :-)
65 - NO problem with having an STL member of class for example string in C++
66 WITH THE RESTRICTION OF FORGETING ABOUT INCREMENTAL LINK.
67 - Python test of dcmlib in Python is ok under windows on a large set
69 * removed glib references
70 * typedef's inserted in gdcm.i for correct swig type management
72 2002-11-27 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
73 * python/demo/*.py load.py extracted from test.py. Added explore.py
74 that only displays required tags and testAll.py that parses all
75 the files of the testsuite without using unittest.
76 * python/testSuite.py other additional test on new files added.
77 * Data/* new test files added accordingly to the testSuite.
78 * src/gdcmHeader.cxx avoid overwriting of the dictionary when
79 the vr in the file differs from the one of the dictionary.
81 2002-11-20 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
82 * src/gdcm.h and gdcmHeader.cxx gdcm no longer loads all the elements
83 values, but limits itself to values which are below a user specified
84 size (by default 1024 bytes).
85 * python/gdcm.i : elements not loaded (because their size is above the
86 user specified treshold) are exported with their TagKey as key of the
87 python dictionary. This enables the testsuite to make some checks
88 on the unloaded elements (since we have their offset and size).
90 - now tests for the existence and proper value of the pixel data
91 - two new examples added.
92 * Data/gdcm-MR-SIEMENS-16.acr[12] added.
94 2002-11-18 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
95 * src/gdcm.h and gdcmHeader.cxx are now "Big Endian transfer syntax"
96 aware. See the strategy comments in gdcmHeader::FindeLength().
97 * Test/test.cxx now accepts a filename as first argument.
98 * Data/US-PAL-8-10x-echo.dcm and US-RGB-8-epicard.dcm added.
99 * python/testSuite.py changed to integrate test on above files.
101 2002-11-15 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
102 * Dicts/dicomV3.dic removed all the trailing (RET) when the
104 * python/testSuite.py more tests added.
106 2002-11-14 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
107 * python/testSuite.py unittest test suite added (uses Data)
108 * Data/* dcm and acr files for the test suite.
109 * glib dependance removed from un*x version. We now use ISO C99
110 7.18 Integer types (see stdint.h)
111 - python/Makefile, src/Makefile src/gdcm.h
112 * src/ when an explicit vr (like dicom files) suddenly poped an
113 implicit element we use to mark the underlying DictEntry of the
114 concerned ElValue with "Implicit". This strategy was damageable
115 too the public or provite dictionaries, since some of their vr
116 would be changed. Since Header::FindLength heavily relies on the
117 detection by Header::FindVR of falsely explicit elements, I
118 added an extra ImplicitVr member to ElValue (boolean).
119 The rest of the changes we the necessary adaptations.
121 2002-11-12 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
122 * src/gdcmHeader::FindLength bug fix when trapping falsely explicit
124 * src/gdcmHeader::FindVR: hard way fix of falsely explicit vr files.
126 2002-11-8 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
127 * Adaptation for porting to VC++:
129 o forced to use std namespace (for string to be known)
130 o all class use __declspec export style on WIN32
131 - src/gdcmUtil.cxx new Exit method that wraps the exit call
132 (in stdlib.h on Win32 but in std:: for gcc)
133 * src/gdcmDictSet::SetDictPath adds a trailing / to environement
134 variable GDCM_DICT_PATH.
135 * src/gdcmHeader.cxx verbose comments made discrete.
137 2002-11-7 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
138 * python/gdcm.i: added a typemap that converts a C++ hashing table
139 to native Python dictionary.
140 * python/demo/test.py:
141 - now uses the native dictionary for exploration of gdcmHeader.
142 - takes an optional filename argument (the file to parse).
143 * src/gdcm.h and gdcmHeader.cxx: gdcmHeader now has an accessor on
144 PubElVals hashing table.
145 * Dicts/dicomV3.dic removed error prone trailing spaces.
147 2002-11-6 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
148 * Python wrapping process moved away from src/Makefile to
149 newly created python/Makefile (as well as gdcm.i)
150 * python/demo/test.py (that mirrors Test/test.cxx) is effective.
151 * src/gdcmHeader::FindLength only looks for current vr when necessary.
152 * src/gdcmDictSet.cxx: the dictionnaries directory path is now imported
153 from the environement variable GDCM_DICT_PATH (when existing).
154 * src/gdcmDict::GetTag bug fix.
156 2002-10-31 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
157 * Straightforward temporary fixes for swig to build the python wrappers.
158 src/Makefile now has a python working entry [by working we mean
159 that we can import de shadow classes without errors].
161 2002-10-29 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
162 * hashtest.cxx removed (since allready in Test)
163 * src/gdcmlib.h renamed to src/gdcm.h
164 * src/dcm.i renamed to src/gdcm.i
165 * src/Makefile prepared for python wrapping
167 2002-10-29 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
168 * src/gdcmHeader.cxx :
169 - Parsing of header is now separated from loading of element values
170 (see gdcmHeader::LoadElements).
171 - general clean up of hopefully all file access (creation of
172 ReadInt16 and ReadInt32)
174 2002-10-22 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
175 * src/gdcmHeader.cxx :
176 - RecupLgr renamed to FindLength and cut off with new IsAnInteger
178 - SetLgrElem renamed to SetLength
179 - GetLgrElem renamed to GetLength
180 - ~gdcmHeader() made virtual to pesky warning messages at compile.
181 * src/gdcmElValSet.cxx fixed both GetElValue methods
182 * Dicts/dicomV3.dic falacious entry [7fe0 0010 OT PXL Pixel Data]
183 due to IdoDude was cleaned out.
185 2002-10-21 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
186 * src/gdcmHeader.cxx RecupLgr split in FindVR and RecupLgr. FindVR
187 concentrates on finding the value representation (when it exists).
188 RecupLgr now only finds the element value length, and it avoids
189 returning the unecessary skL (skipped length).
190 Also, offsetCourant was simply removed (with taille_fich) since
191 it was redundant with the File position internals (by using
192 ftell and fseek). This also made skL (see above in RecupLgr) usage
194 * src/gdcmHeaderIdo.cxx src/gdcmIdo.h added. Those files concentrate
195 on the libido specificities which are handled through class
197 * Test/implicit_vr.dcm dicom v3 in implicit value representation
200 2002-10-17 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
201 * Truckload of changes. Parsing of header is barely functional
202 (see Test/test) with the standard dictionary (see Dicts/dicomV3.dic).
204 2002-10-10 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
205 * src/gdcmHeader.cxx many addons of low level methods
207 2002-10-07 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
208 * src/gdcmHeader now contains_IdDcmCheckSwap, _IdDcmRecupLgr,
211 2002-09-12 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
212 * This corresponds to all the changes decided at the meeting of
213 May 23 2002. Needless to say we are running late...
