 * CVS/RCS Log:
 * $Log: dicopx.h,v $
 * Revision 1.16  2005/12/08 16:01:34  meichel
 * Changed include path schema for all DCMTK header files
 *
 * Revision 1.15  2004/10/19 12:57:47  joergr
 * Enhanced API documentation.
 *
 * Revision 1.14  2003/12/17 18:18:08  joergr

 * symbols).
 *
 * Revision 1.13  2002/09/12 14:10:37  joergr
 * Replaced "createPixelData" by "getPixelData" which uses a new dcmdata
 * routine and is therefore more efficient.
 *
 * Revision 1.12  2002/08/29 12:57:49  joergr
 * Added method that creates pixel data in DICOM format.
 *
 * Revision 1.11  2002/01/29 17:07:08  joergr
 * Added optional flag to the "Windows DIB" methods allowing to switch off the
 * scanline padding.
 *
 * Revision 1.10  2001/11/09 16:44:01  joergr
 * Enhanced and renamed createTrueColorDIB() method.
 * Updated/Enhanced comments.
 *
 * Revision 1.9  2001/06/01 15:49:29  meichel
 * Updated copyright header
 *
 * Revision 1.8  2000/03/08 16:21:51  meichel
 * Updated copyright header.
 *
 * Revision 1.7  1999/04/29 09:31:13  joergr
 * Moved color related image files back to non-public part.
 *
 * Revision 1.1  1999/04/28 14:57:32  joergr
 * Moved files from dcmimage module to dcmimgle to support new pastel color
 * output format.
 *
 * Revision 1.5  1999/01/20 14:44:04  joergr
 * Corrected some typos and formatting.
 *
 * Revision 1.4  1998/11/27 13:47:54  joergr
 * Added copyright message. Added method to directly create java AWT bitmaps.
 *
 * Revision 1.3  1998/05/11 14:53:13  joergr
 * Added CVS/RCS header to each file.
