[gdcm.git] / ChangeLog

2003-02-20 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcmHeader.cxx : bug fix - opening dicom file in binary !!!
      * modifications in MSVC projects

2003-02-19 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * As stated by the first lines of Test/ExceptionAndPython/README, it
        looks like we can move back to original usage of exception within
        src/gdcm* and hence remove the errno stuff that was introduced
        as a quick and dirty fixture of this problem (added to the TODO).
      * Doc/Doxyfile configuration file for Doxygen and corresponding
        README file for usage added.
      * Test/testWrite.cxx added. This new test comes from a split of
        test.cxx that is now reverted to its original purpous i.e. 
        testing the proper parsing of a Dicom related file.
        testWrite.cxx concentrates on testing the IO part of gdcm.
      * Test/bug1.cxx (containing a bug on WIn32) added.
      * src/gdcm.h, gdcmHeader.cxx, gdcmDictSet.cxx: 
        - gdcmHeader::GetPubTagNames and  gdcmHeader::GetPubTagNamesByCategory
          whose purpose is to publish the content of the TagNames of the
          Dicom public dictionnary were not accessible without an
          instance of class gdcmHeader.
        - those methods are now static methods of gdcmDictSet and hence
          require no instances at all to be invocated.
        - within gdcmDictSet this change required to change some method
          to class methods (i.e. are now static) among which SetDictPath
          (renamed to BuildDictPath) and LoadDefaultPubDict.
      * python/gdcmPython/demo/printGroupedPublicDict.py changed to illustrate
        the above changes by calling the new method classes of gdcmDictSet.
      * python/gdcmPython/__init__.py now exposes gdcm.gdcmDictSet for
        the above to be effective.
      * python/gdcmPython: in order to wrap properly the above changes
        for Python, swig version now needs to be > 1.3.17.
      * python/gdcmPython/Makefile fixed to adapt itself to new 
        configure/make shema introduced by Johan Montagnat (thanks for the
        contribution). Alas this Makefile cannot be turned into a proper
        Makefile.am without some heavy changes in the configure.in
        (for python dectection).
      * python/gdcmPython/gdcm.i: the out typemap map<string, list<string>>*
        now avoids publishing the empty entries.

2003-02-13 Benoit Regrain <Benoit.Regrain@creatis.insa-lyon.fr>
      * python/setup.py : bug fix concerning install under windows
        ExtraPath reused :-P
      * gdcm.dsw : bug fix concerning path for libraries for python !!!

2003-02-13 Benoit Regrain <Benoit.Regrain@creatis.insa-lyon.fr>
      * Dicts/dicomV3.dic : remove double spaces !!!
      * src/gdcmElValSet.cxx : bug fix concerning windows compiler
      * python/gdcmPython/win32/gdcmpycomplet.dsp : bug fix concerning paths
        and links

2003-01-28 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcmHeader.cxx added a post header parsing AddAndDefaultElements
        method. Doxygenation.
      * src/gdcm.h clean up of JPR spurious comments.

2003-01-17 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * python/distutilsSwigCPlusPlus.py now properly collects the
        shadow classes generated by "swig -c++" (gdcm.py in our case)
        when using "python setup.py install".
      * python/gdcmPython/__init__.py imports gdcm.py and only manually
        reexports the working classes.
      * src/gdcmHeader.cxx all the try/catch/throw calls were replaced
        by the classical C errno scheme. This is to prevent an obscure
        behavior of the python wrappers when importing wxPython.wx prior
        to gdcmPython (which ended up in an abort call). An illustration
        of this oddity can be found in the Test/ExceptionAndPython
        subdir (see the README file). This problem probably due to
        an combination of g++ and dynamic loading.
      * added Test/ExceptionAndPython (see above)

2003-01-17 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * Changed the layout of the python part to avoid bloating main
        directory with setup.py, distutilsSwigCPlusPlus.py, MANIFEST.in
        i.e. the distutils arsenal. All the python related stuff is
        again in a python subdir, but the package itself is now in
        python/gdcmPython.
      * setup.py was cleaned up:
        - pythonIncludePath removed
        - python setup.py bdist target is now functional.
      * gdcmPython/__init__.py doesn't export FileName any more (to avoid
        collision with other packages). gdcmPython/demo/*.py changed
        accordingly.
2003-01-15 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * python subdir moved to gdcmPython (preparation of distutils packaging).
      * gdcmPython/setup.py and distutilsSwigCPlusPlus.py added. The
        distutils installer is operational.
      * - gdcmPython/__init__.py now properly loads the swig generated
          shadow classes (from gdcm.py).
        - gdcmPython/demo/*.py changed to import the package gdcmPython
          instead of gdcmPython/demo/load.py.
        - gdcmPython/testSuite.py changed to import the package gdcmPython.
        

2002-12-16 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcm.h, src/gdcmHeader.cxx: added GetPubTagNames() resp.
        GetPubTagNamesByCategory() to gdcmHeader that return a list of the
        entries within the associated public Dicom dictionary resp. the same
        information but sorted by the fourth field (PAT, IMG, DIR) of the
        dictionary.
        - Dicts/dicomV3.dic Entries which had and unspecified fourth field
          are now in the "???" group.
        - python/gdcm.i changed accordingly,
        - python/demo/printGroupedPublicDict.py added, that gives an example
          of the above new functionalities in Python.

2002-12-11 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcm.h, gdcmHeader.cxx:
        - historic references to glib's g_malloc and g_free (#defined)
          were definitively removed.
        - gdcm.h: cosmetic changes (part of comments moved to Doc/requirements)
      * src/gdcmElValSet.cxx:
        - GetElement(guint32, guint32) renamed to GetElementByNumber.
        - GetElValue(guint32, guint32) renamed to GetElValueByNumber.
        - GetElValue(string) renamed to GetElValueByName.
        - Added GetElementByName(string).
      * src/gdcmHeader.cxx: added
        - GetPubElValRepByNumber(guint16, guint16)
        - GetPubElValRepByName(string)
        - GetShaElValRepByNumber(guint16, guint16)
        - GetShaElValRepByName(string)
        - GetShaElValByNumber(guint16, guint16)
        - GetShaElValRepByName(string)
        - GetElValRepByNumber(guint16, guint16)
        - GetElValRepByName(string)
        - GetElValByNumber(guint16, guint16)
        - GetElValRepByName(string)
      * Doc/requirements.txt added.

2002-12-9 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * Test/Makefile building now depends on the one of libgdcm.so
      * src/gdcmHeader.cxx and gdcm.h are now OB (undefined length encoded
        pixel data) aware which enables finding the address (offset) of 
        the pixel data of JPEG encoded DICOM files. This leaves only a single
        file in the testSuite whose pixel data address (offset) is unknown.
      * python/testSuite.py changed accordingly.

2002-12-6 Christophe Odet + Hugues Benoit-Cattin + Eric.Boix
      * VC++ has some strong limitations when working with the STL, as stated
        in http://support.microsoft.com/support/kb/articles/Q168/9/58.ASP :
             "Also note that some STL containers (map, set, queue, list, deque)
              cannot be exported. [...]
              Some STL classes contain nested classes. These classes can not
              be exported. [...]
              This is caused by a designed limitation that once a template
              class is instantiated, it can not be re-instantiated and
              exported."
        Since our usage of map<> is ubiquitous in gdcm, this "designed
        limitation" of VC++ is a pitfall.
        Hence the Python wrappers of gdcm cannot be incrementally linked 
        against the c++ dynamic library. The dirty but only workaround is
        to forget about incremental link of dynamic libraries and to generate
        the Python wrappers library with the inclusions of the underlying C++
        library. 
        The following modifications concern this matter on Win32/VC++:
      - wrapping python correct with standalone wrapped dll (don't use separate
         dll under windows !!!!)
      - python21_d debug mode enabled (ask Frog how to use it :-)
      - NO problem with having an STL member of class for example string in C++
        WITH THE RESTRICTION OF FORGETING ABOUT INCREMENTAL LINK.
      - Python test of dcmlib in Python is ok under windows on a large set 
        (one) of image(s).
      * removed glib references
      * typedef's inserted in gdcm.i for correct swig type management

2002-11-27 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * python/demo/*.py load.py extracted from test.py. Added explore.py
        that only displays required tags and testAll.py that parses all
        the files of the testsuite without using unittest.
      * python/testSuite.py other additional test on new files added.
      * Data/* new test files added accordingly to the testSuite.
      * src/gdcmHeader.cxx avoid overwriting of the dictionary when
        the vr in the file differs from the one of the dictionary.

2002-11-20 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcm.h and gdcmHeader.cxx gdcm no longer loads all the elements
        values, but limits itself to values which are below a user specified
        size (by default 1024 bytes).
      * python/gdcm.i : elements not loaded (because their size is above the
        user specified treshold) are exported with their TagKey as key of the
        python dictionary. This enables the testsuite to make some checks
        on the unloaded elements (since we have their offset and size).
      * python/testSuite.py
        - now tests for the existence and proper value of the pixel data
        - two new examples added.
      * Data/gdcm-MR-SIEMENS-16.acr[12] added.

2002-11-18 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcm.h and gdcmHeader.cxx are now "Big Endian transfer syntax"
        aware. See the strategy comments in gdcmHeader::FindeLength().
      * Test/test.cxx now accepts a filename as first argument.
      * Data/US-PAL-8-10x-echo.dcm and US-RGB-8-epicard.dcm added.
      * python/testSuite.py changed to integrate test on above files.

2002-11-15 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * Dicts/dicomV3.dic removed all the trailing (RET) when the
        the vr was also RET.
      * python/testSuite.py more tests added.

2002-11-14 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * python/testSuite.py unittest test suite added (uses Data)
      * Data/* dcm and acr files for the test suite.
      * glib dependance removed from un*x version. We now use ISO C99
        7.18 Integer types (see stdint.h)
        - python/Makefile, src/Makefile src/gdcm.h
      * src/ when an explicit vr (like dicom files) suddenly poped an
        implicit element we use to mark the underlying DictEntry of the
        concerned ElValue with "Implicit". This strategy was damageable
        too the public or provite dictionaries, since some of their vr
        would be changed. Since Header::FindLength heavily relies on the
        detection by Header::FindVR of falsely explicit elements, I
        added an extra ImplicitVr member to ElValue (boolean).
        The rest of the changes we the necessary adaptations.

2002-11-12 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcmHeader::FindLength bug fix when trapping falsely explicit
        VR files.
      * src/gdcmHeader::FindVR: hard way fix of falsely explicit vr files.

2002-11-8 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * Adaptation for porting to VC++:
        - src/gdcm.h
          o forced to use std namespace (for string to be known)
          o all class use __declspec export style on WIN32
        - src/gdcmUtil.cxx new Exit method that wraps the exit call
          (in stdlib.h on Win32 but in std:: for gcc)
      * src/gdcmDictSet::SetDictPath adds a trailing / to environement
        variable GDCM_DICT_PATH.
      * src/gdcmHeader.cxx verbose comments made discrete.

2002-11-7 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * python/gdcm.i: added a typemap that converts a C++ hashing table
        to native Python dictionary.
      * python/demo/test.py:
        - now uses the native dictionary for exploration of gdcmHeader.
        - takes an optional filename argument (the file to parse).
      * src/gdcm.h and gdcmHeader.cxx: gdcmHeader now has an accessor on
        PubElVals hashing table. 
      * Dicts/dicomV3.dic removed error prone trailing spaces.

2002-11-6 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * Python wrapping process moved away from src/Makefile to
        newly created python/Makefile (as well as gdcm.i)
      * python/demo/test.py (that mirrors Test/test.cxx) is effective.
      * src/gdcmHeader::FindLength only looks for current vr when necessary.
      * src/gdcmDictSet.cxx: the dictionnaries directory path is now imported
        from the environement variable GDCM_DICT_PATH (when existing).
      * src/gdcmDict::GetTag bug fix.

2002-10-31 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * Straightforward temporary fixes for swig to build the python wrappers.
        src/Makefile now has a python working entry [by working we mean
        that we can import de shadow classes without errors].

2002-10-29 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * hashtest.cxx removed (since allready in Test)
      * src/gdcmlib.h renamed to src/gdcm.h
      * src/dcm.i renamed to src/gdcm.i
      * src/Makefile prepared for python wrapping

2002-10-29 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcmHeader.cxx :
        - Parsing of header is now separated from loading of element values
          (see gdcmHeader::LoadElements).
        - general clean up of hopefully all file access (creation of
          ReadInt16 and ReadInt32)

2002-10-22 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcmHeader.cxx :
        - RecupLgr renamed to FindLength and cut off with new IsAnInteger
          method.
        - SetLgrElem renamed to SetLength
        - GetLgrElem renamed to GetLength
        - ~gdcmHeader() made virtual to pesky warning messages at compile.
      * src/gdcmElValSet.cxx fixed both GetElValue methods
      * Dicts/dicomV3.dic falacious entry [7fe0 0010 OT PXL Pixel Data]
        due to IdoDude was cleaned out.

2002-10-21 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcmHeader.cxx RecupLgr split in FindVR and RecupLgr. FindVR
        concentrates on finding the value representation (when it exists).
        RecupLgr now only finds the element value length, and it avoids
        returning the unecessary skL (skipped length).
        Also, offsetCourant was simply removed (with taille_fich) since
        it was redundant with the File position internals (by using
        ftell and fseek). This also made skL (see above in RecupLgr) usage
        jajun.
      * src/gdcmHeaderIdo.cxx src/gdcmIdo.h added. Those files concentrate
        on the libido specificities which are handled through class 
        inheritance.
      * Test/implicit_vr.dcm dicom v3 in implicit value representation
        added. 

2002-10-17 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * Truckload of changes. Parsing of header is barely functional
        (see Test/test) with the standard dictionary (see Dicts/dicomV3.dic).

2002-10-10 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcmHeader.cxx many addons of low level methods

2002-10-07 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * src/gdcmHeader now contains_IdDcmCheckSwap, _IdDcmRecupLgr,
        and _IdDcmSWAP_LONG.

2002-09-12 Eric Boix <Eric.Boix@creatis.insa-lyon.fr>
      * This corresponds to all the changes decided at the meeting of
        May 23 2002. Needless to say we are running late...
