/*
 *
 * CVS/RCS Log:
 * $Log: dimopx.h,v $
 * Revision 1.18  2005/12/08 16:47:55  meichel
 * Changed include path schema for all DCMTK header files
 *
 * Revision 1.17  2004/02/06 11:07:50  joergr
 * Distinguish more clearly between const and non-const access to pixel data.
 *
 * Revision 1.16  2003/12/08 18:45:29  joergr
 * Adapted type casts to new-style typecast operators defined in ofcast.h.
 * Removed leading underscore characters from preprocessor symbols (reserved
 * symbols). Updated copyright header.
 *
 * Revision 1.15  2002/12/09 13:32:54  joergr
 * Renamed parameter/local variable to avoid name clashes with global
 * declaration left and/or right (used for as iostream manipulators).
 *
 * Revision 1.14  2001/11/19 12:56:15  joergr
 * Added parameter 'frame' to setRoiWindow().
 *
 * Revision 1.13  2001/09/28 13:07:43  joergr
 * Added method setRoiWindow() which automatically calculates a min-max VOI
 * window for a specified rectangular region of the image.
 *
 * Revision 1.12  2001/06/01 15:49:47  meichel
 * Updated copyright header
 *
 * Revision 1.11  2000/03/08 16:24:20  meichel
 * Updated copyright header.
 *
 * Revision 1.10  1999/10/06 13:43:29  joergr
 * Corrected creation of PrintBitmap pixel data: VOI windows should be applied
 * before clipping to avoid that the region outside the image (border) is also
 * windowed (this requires a new method in dcmimgle to create a DicomImage
 * with the grayscale transformations already applied).
 *
 * Revision 1.9  1999/09/17 12:41:26  joergr
 * Added/changed/completed DOC++ style comments in the header files.
 *
 * Revision 1.8  1999/05/31 12:35:16  joergr
 * Corrected bug concerning the conversion of color images to grayscale.
 *
 * Revision 1.7  1999/04/28 17:03:48  joergr
 * Added type casts to NULL pointers returned as 'const char *' to avoid
 * compiler warnings reported by gcc 2.7.2.1 (Linux).
 *
 * Revision 1.6  1999/03/24 17:20:15  joergr
 * Added/Modified comments and formatting.
 *
 * Revision 1.5  1999/02/03 17:33:18  joergr
 * Added member variable and related methods to store number of bits used for
 * pixel data.
 *
 * Revision 1.4  1999/01/11 09:35:56  joergr
 * Corrected some typos and formatting.
 *
 * Revision 1.3  1998/12/22 14:33:45  joergr
 * Added implementation of methods to return member variables AbsMinimum/
 * Maximum.
 *
 * Revision 1.2  1998/12/16 16:35:39  joergr
 * Added explanation string to LUT class (retrieved from dataset).
 *
 * Revision 1.1  1998/11/27 15:33:16  joergr
 * Added copyright message.
 * Introduced new pixel base class.
 *
 * Revision 1.4  1998/07/01 08:39:24  joergr
 * Minor changes to avoid compiler warnings (gcc 2.8.1 with additional
 * options), e.g. add copy constructors.
 *
 * Revision 1.3  1998/05/11 14:53:23  joergr
 * Added CVS/RCS header to each file.
