/*
 *
 * CVS/RCS Log:
 * $Log: dimoimg.h,v $
 * Revision 1.43  2004/02/06 11:07:50  joergr
 * Distinguish more clearly between const and non-const access to pixel data.
 *
 * Revision 1.42  2003/12/23 10:51:52  joergr
 * Updated documentation to get rid of doxygen warnings.
 *
 * Revision 1.41  2003/12/17 16:17:29  joergr
 * Added new compatibility flag that allows to ignore the third value of LUT
 * descriptors and to determine the bits per table entry automatically.
 *
 * Revision 1.40  2003/12/08 18:30:16  joergr
 * Adapted type casts to new-style typecast operators defined in ofcast.h.
 * Removed leading underscore characters from preprocessor symbols (reserved
 * symbols). Updated CVS header.
 *
 * Revision 1.39  2003/06/12 15:08:34  joergr
 * Fixed inconsistent API documentation reported by Doxygen.
 *
 * Revision 1.38  2003/05/20 09:20:21  joergr
 * Added method returning the number of bytes required to store a single
 * rendered frame: getOutputDataSize().
 *
 * Revision 1.37  2002/12/09 13:32:52  joergr
 * Renamed parameter/local variable to avoid name clashes with global
 * declaration left and/or right (used for as iostream manipulators).
 *
 * Revision 1.36  2002/08/02 15:03:53  joergr
 * Added function to write the current image (not only a selected frame) to a
 * DICOM dataset.
 *
 * Revision 1.35  2002/06/26 17:20:04  joergr
 * Removed superfluous "inline" method specifyer (MSVC6 linker reported an
 * error).
 *
 * Revision 1.34  2002/06/26 16:04:44  joergr
 * Added support for polarity flag to color images.
 * Added new methods to get the explanation string of stored VOI windows and
 * LUTs (not only of the currently selected VOI transformation).
 *
 * Revision 1.33  2002/01/29 17:05:50  joergr
 * Added optional flag to the "Windows DIB" methods allowing to switch off the
 * scanline padding.
 *
 * Revision 1.32  2001/11/19 12:55:54  joergr
 * Added parameter 'frame' to setRoiWindow().
 *
 * Revision 1.31  2001/11/09 16:27:34  joergr
 * Added support for Window BMP file format.
 * Enhanced and renamed createTrueColorDIB() method.
 *
 * Revision 1.30  2001/09/28 13:06:10  joergr
 * Added routines to get the currently active Polarity and PresentationLUTShape.

 * window for a specified rectangular region of the image.
 * Added method to extract embedded overlay planes from pixel data and store
 * them in group (6xxx,3000) format.
 *
 * Revision 1.29  2001/06/01 15:49:44  meichel
 * Updated copyright header
 *
 * Revision 1.28  2001/05/14 09:49:17  joergr
 * Added support for "1 bit output" of overlay planes; useful to extract
 * overlay planes from the pixel data and store them separately in the dataset.
 *
 * Revision 1.27  2000/07/07 13:42:30  joergr
 * Added support for LIN OD presentation LUT shape.
 *
 * Revision 1.26  2000/06/07 14:30:27  joergr

 *
 * Revision 1.25  2000/03/08 16:24:18  meichel
 * Updated copyright header.
 *
 * Revision 1.24  1999/12/09 17:26:24  joergr

 * Enhanced method getOverlayData to support 12 bit data for print.
 *
 * Revision 1.22  1999/10/06 13:38:46  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 1.21  1999/09/17 12:24:47  joergr
 * Added/changed/completed DOC++ style comments in the header files.
 *

 *
 * Revision 1.19  1999/08/25 16:41:52  joergr
 * Added new feature: Allow clipping region to be outside the image
 * (overlapping).
 *
 * Revision 1.18  1999/07/23 14:03:05  joergr
 * Added dummy method (no implementation yet) to create inverse LUTs.
 * Added method to create 12 bit packed bitmap data (used for grayscale print
 * storage).
 * Added method to return pointer to currently used display function.
 *
 * Revision 1.17  1999/04/28 17:03:47  joergr
 * Added type casts to NULL pointers returned as 'const char *' to avoid
 * compiler warnings reported by gcc 2.7.2.1 (Linux).
 *
 * Revision 1.16  1999/04/28 14:49:54  joergr
 * Added experimental support to create grayscale images with more than 256
 * shades of gray to be displayed on a consumer monitor (use pastel colors).
 *
 * Revision 1.15  1999/03/24 17:20:09  joergr

 *
 * Revision 1.14  1999/03/22 08:51:39  joergr
 * Added parameter to specify (transparent) background color for method
 * getOverlayData().
 *
 * Revision 1.13  1999/02/11 16:34:36  joergr
 * Added routine to check whether particular grayscale values are unused in
 * the output data.
 *
 * Revision 1.12  1999/02/08 12:39:05  joergr
 * Changed implementation of removeAllOverlays().
 *
 * Revision 1.11  1999/02/05 16:43:13  joergr
 * Added optional parameter to method convertPValueToDDL to specify width
 * of output data (number of bits).
 *
 * Revision 1.10  1999/02/03 17:27:58  joergr
 * Added support for calibration according to Barten transformation (incl.
 * a DISPLAY file describing the monitor characteristic).
 *
 * Revision 1.9  1999/01/20 15:03:40  joergr
 * Added new output method to fill external memory buffer with rendered pixel
 * data.
 *
 * Revision 1.8  1999/01/11 09:35:10  joergr
 * Added parameter to method 'getMinMaxValues()' to return absolute minimum
 * and maximum values ('possible') in addition to actually 'used' pixel
 * values.
 *
 * Revision 1.7  1998/12/23 13:21:28  joergr
 * Changed parameter type (long to int) to avoid warning reported by MSVC5.
 *
 * Revision 1.6  1998/12/23 12:38:16  joergr
 * Corrected some typos and formatting.
 *
 * Revision 1.4  1998/12/22 14:26:19  joergr
 * Added new parameters to method addOverlay().

 * Added explanation string to LUT class (retrieved from dataset).
 * Added explanation string for VOI transformations.
 * Renamed 'setNoVoiLutTransformation' method ('Voi' instead of 'VOI').
 * Removed several methods used for monochrome images only in base class
 * 'DiImage'. Introduced mechanism to use the methods directly.
 *
 * Revision 1.2  1998/12/14 17:20:03  joergr
 * Added methods to add and remove additional overlay planes (still untested).
 *

 *
 * Revision 1.6  1998/07/01 08:39:22  joergr
 * Minor changes to avoid compiler warnings (gcc 2.8.1 with additional
 * options), e.g. add copy constructors.
 *
 * Revision 1.5  1998/05/11 14:53:20  joergr
 * Added CVS/RCS header to each file.
