** CVS/RCS Log:
** $Log: dcvrus.cc,v $
** Revision 1.25 2005/12/08 15:42:09 meichel
** Changed include path schema for all DCMTK header files
**
** Revision 1.24 2004/02/04 16:04:56 joergr
** Adapted type casts to new-style typecast operators defined in ofcast.h.
** Removed acknowledgements with e-mail addresses from CVS log.
**
** Revision 1.23 2002/12/06 13:12:37 joergr
** Enhanced "print()" function by re-working the implementation and replacing
** the boolean "showFullData" parameter by a more general integer flag.
** Made source code formatting more consistent with other modules/files.
**
** Revision 1.22 2002/11/27 12:07:00 meichel
** Adapted module dcmdata to use of new header file ofstdinc.h
**
** Revision 1.21 2002/04/25 10:35:04 joergr
** Added getOFString() implementation.
**
** Revision 1.20 2002/04/16 13:43:27 joergr
** Added configurable support for C++ ANSI standard includes (e.g. streams).
**
** Revision 1.19 2001/09/25 17:20:02 meichel
** Adapted dcmdata to class OFCondition
**
** Revision 1.18 2001/06/01 15:49:22 meichel
** Updated copyright header
**
** Revision 1.17 2000/04/14 15:55:10 meichel
** Dcmdata library code now consistently uses ofConsole for error output.
**
** Revision 1.16 2000/03/08 16:26:52 meichel
** Updated copyright header.
**
** Revision 1.15 2000/03/03 14:05:41 meichel
** Implemented library support for redirecting error messages into memory
** instead of printing them to stdout/stderr for GUI applications.
**
** Revision 1.14 2000/02/10 10:52:26 joergr
** Added new feature to dcmdump (enhanced print method of dcmdata): write
** pixel data/item value fields to raw files.
**
** Revision 1.13 2000/02/02 14:33:03 joergr
** Replaced 'delete' statements by 'delete[]' for objects created with 'new[]'.
**
** Revision 1.12 1999/03/31 09:26:03 meichel
** Updated copyright header in module dcmdata
**
** Revision 1.11 1997/07/21 08:25:37 andreas
** - Replace all boolean types (BOOLEAN, CTNBOOLEAN, DICOM_BOOL, BOOL)
** with one unique boolean type OFBool.
**
** Revision 1.10 1997/07/03 15:10:22 andreas
** - removed debugging functions Bdebug() and Edebug() since
** they write a static array and are not very useful at all.
** Cdebug and Vdebug are merged since they have the same semantics.
** The debugging functions in dcmdata changed their interfaces
** (see dcmdata/include/dcdebug.h)
**
** Revision 1.9 1997/04/18 08:10:54 andreas
** - Corrected debugging code
** - The put/get-methods for all VRs did not conform to the C++-Standard
** draft. Some Compilers (e.g. SUN-C++ Compiler, Metroworks
** CodeWarrier, etc.) create many warnings concerning the hiding of
** overloaded get methods in all derived classes of DcmElement.
** So the interface of all value representation classes in the
** library are changed rapidly, e.g.
** OFCondition get(Uint16 & value, const unsigned long pos);
** becomes
** OFCondition getUint16(Uint16 & value, const unsigned long pos);
** All (retired) "returntype get(...)" methods are deleted.
** For more information see dcmdata/include/dcelem.h
**
** Revision 1.8 1996/08/05 08:46:25 andreas
** new print routine with additional parameters:
** - print into files
** - fix output length for elements
** corrected error in search routine with parameter ESM_fromStackTop
**
** Revision 1.7 1996/05/20 13:27:54 andreas
** correct minor bug in print routine
**
** Revision 1.6 1996/04/16 16:05:27 andreas
** - better support und bug fixes for NULL element value
**
** Revision 1.5 1996/03/26 09:59:39 meichel
** corrected bug (deletion of const char *) which prevented compilation on NeXT
**
** Revision 1.4 1996/01/29 13:38:35 andreas
** - new put method for every VR to put value as a string
** - better and unique print methods
**
** Revision 1.3 1996/01/05 13:27:56 andreas
** - changed to support new streaming facilities
** - unique read/write methods for file and block transfer
** - more cleanups
**
