 * CVS/RCS Log:
 * $Log: dicoimg.h,v $
 * Revision 1.20  2004/02/06 11:18:18  joergr
 * Distinguish more clearly between const and non-const access to pixel data.
 *
 * Revision 1.19  2003/12/17 18:10:56  joergr
 * Removed leading underscore characters from preprocessor symbols (reserved
 * symbols).
 *
 * Revision 1.18  2003/06/12 15:09:41  joergr
 * Fixed inconsistent API documentation reported by Doxygen.
 *
 * Revision 1.17  2003/05/20 09:26:05  joergr
 * Added method returning the number of bytes required to store a single
 * rendered frame: getOutputDataSize().
 *
 * Revision 1.16  2002/12/09 13:37:51  joergr
 * Renamed parameter/local variable to avoid name clashes with global
 * declaration left and/or right (used for as iostream manipulators).
 *
 * Revision 1.15  2002/08/02 15:07:02  joergr
 * Added function to write the current image (not only a selected frame) to a
 * DICOM dataset.
 *
 * Revision 1.14  2002/01/29 17:07:07  joergr
 * Added optional flag to the "Windows DIB" methods allowing to switch off the
 * scanline padding.
 *
 * Revision 1.13  2001/11/27 18:22:17  joergr
 * Added support for plugable output formats in class DicomImage. First
 * implementation is JPEG.
 *
 * Revision 1.12  2001/11/09 16:38:36  joergr
 * Added support for Windows BMP file format.
 * Enhanced and renamed createTrueColorDIB() method.
 * Updated/Enhanced comments.
 *
 * Revision 1.11  2001/09/28 13:55:40  joergr
 * Added new flag (CIF_KeepYCbCrColorModel) which avoids conversion of YCbCr
 * color models to RGB.
 *
 * Revision 1.10  2001/06/01 15:49:28  meichel
 * Updated copyright header
 *
 * Revision 1.9  2000/03/08 16:21:50  meichel
 * Updated copyright header.
 *
 * Revision 1.8  1999/08/25 16:58:06  joergr
 * Added new feature: Allow clipping region to be outside the image
 * (overlapping).
 *
 * Revision 1.7  1999/04/28 12:51:57  joergr
 * Corrected some typos, comments and formatting.
 *
 * Revision 1.6  1999/01/20 14:39:52  joergr
 * Added new output method to fill external memory buffer with rendered pixel
 * data.
 *
 * Revision 1.5  1998/11/27 13:43:29  joergr
 * Added methods and constructors for flipping and rotating, changed for
 * scaling and clipping.
 *
 * Revision 1.4  1998/07/01 08:39:18  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 14:53:11  joergr
 * Added CVS/RCS header to each file.
