/*
 * CVS/RCS Log:
 * $Log: dctypes.h,v $
 * Revision 1.21  2005/12/08 16:28:47  meichel
 * Changed include path schema for all DCMTK header files
 *
 * Revision 1.20  2005/12/02 08:50:30  joergr
 * Added new file read mode that makes it possible to distinguish between DICOM
 * files, datasets and other non-DICOM files.
 *
 * Revision 1.19  2003/04/22 08:19:09  joergr
 * Added new command line option which allows to embed the content of the DTD
 * instead of referencing the DTD file.
 *
 * Revision 1.18  2003/04/01 14:57:08  joergr
 * Added support for XML namespaces.
 *
 * Revision 1.17  2002/12/06 12:21:00  joergr
 * Enhanced "print()" function by re-working the implementation and replacing
 * the boolean "showFullData" parameter by a more general integer flag.
 *
 * Revision 1.16  2002/11/27 12:07:23  meichel
 * Adapted module dcmdata to use of new header file ofstdinc.h
 *
 * Revision 1.15  2002/07/10 11:45:40  meichel
 * Moved definitions for Uint8, Sint8 ... Float64 from dcmdata to ofstd
 *   since these types are not DICOM specific
 *
 * Revision 1.14  2002/06/06 14:51:13  meichel
 * Corrected code for inclusion of stdlib.h
 *
 * Revision 1.13  2002/05/14 08:20:29  joergr
 * Added support for Base64 (MIME) encoded binary data.
 *
 * Revision 1.12  2002/04/25 10:07:13  joergr
 * Added support for XML output of DICOM objects.
 *
 * Revision 1.11  2001/06/01 15:48:45  meichel
 * Updated copyright header
 *
 * Revision 1.10  2000/03/08 16:26:19  meichel
 * Updated copyright header.
 *
 * Revision 1.9  2000/03/03 14:05:26  meichel
 * Implemented library support for redirecting error messages into memory
 *   instead of printing them to stdout/stderr for GUI applications.
 *
 * Revision 1.8  2000/02/07 14:44:45  meichel
 * The typedef for Sint8 now defaults to char instead of signed char.
 *   This avoids warnings on certain c-front related compilers.
 *   The old behaviour can be restored by compiling with the symbol
 *   CHAR_IS_UNSIGNED defined.
 *
 * Revision 1.7  1999/03/31 09:24:51  meichel
 * Updated copyright header in module dcmdata
 *
