 *
 * Revision 1.33  2004/01/05 14:52:20  joergr
 * Removed acknowledgements with e-mail addresses from CVS log.
 *
 * Revision 1.32  2003/12/08 18:22:26  joergr
 * Removed leading underscore characters from preprocessor symbols (reserved
 * symbols). Updated CVS header.
 *
 * Revision 1.31  2003/06/12 15:08:34  joergr
 * Fixed inconsistent API documentation reported by Doxygen.
 *
 * Revision 1.30  2003/05/20 09:20:41  joergr
 * Added method returning the number of bytes required to store a single
 * rendered frame: getOutputDataSize().
 *
 * Revision 1.29  2002/12/09 13:32:51  joergr
 * Renamed parameter/local variable to avoid name clashes with global
 * declaration left and/or right (used for as iostream manipulators).
 *
 * Revision 1.28  2002/11/27 14:08:04  meichel
 * Adapted module dcmimgle to use of new header file ofstdinc.h
 *
 * Revision 1.27  2002/11/26 14:48:32  joergr
 * Added Smallest/LargestImagePixelValue to the list of attributes to be
 * removed from a newly created dataset.
 *
 * Revision 1.26  2002/08/02 15:03:20  joergr
 * Enhanced writeFrameToDataset() routine (remove out-data DICOM attributes
 * from the dataset).
 * Added function to write the current image (not only a selected frame) to a
 * DICOM dataset.
 *
 * Revision 1.25  2002/06/26 16:01:55  joergr
 * Added support for polarity flag to color images.
 * Added new method to write a selected frame to a DICOM dataset (incl. required
 * attributes from the "Image Pixel Module").
 *
 * Revision 1.24  2002/04/16 13:53:11  joergr
 * Added configurable support for C++ ANSI standard includes (e.g. streams).
 *
 * Revision 1.23  2002/01/29 17:05:50  joergr
 * Added optional flag to the "Windows DIB" methods allowing to switch off the
 * scanline padding.
 *
 * Revision 1.22  2001/11/27 18:18:22  joergr
 * Added support for plugable output formats in class DicomImage. First
 * implementation is JPEG.
 *
 * Revision 1.21  2001/11/09 16:26:37  joergr
 * Added support for Window BMP file format.
 * Enhanced and renamed createTrueColorDIB() method.
 *
 * Revision 1.20  2001/06/20 15:12:49  joergr
 * Enhanced multi-frame support for command line tool 'dcm2pnm': extract all
 * or a range of frames with one call.
 *
 * Revision 1.19  2001/06/01 15:49:42  meichel
 * Updated copyright header
 *
 * Revision 1.18  2000/03/08 16:24:16  meichel

 * Removed space characters before preprocessor directives.
 *
 * Revision 1.16  1999/10/06 13:28:21  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 1.15  1999/09/17 12:12:18  joergr
 * Added/changed/completed DOC++ style comments in the header files.
 *
 * Revision 1.14  1999/08/25 16:39:31  joergr

 * Revision 1.13  1999/07/23 13:53:00  joergr
 * Added support for attribute 'ImagerPixelSpacing'.
 * Added support for attribute 'RepresentativeFrameNumber'.

 *
 * Revision 1.12  1999/04/28 14:47:34  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 1.11  1999/03/24 17:20:01  joergr
 * Added/Modified comments and formatting.
 *

 * Added new output method to fill external memory buffer with rendered pixel
 * data.
 *
 * Revision 1.7  1999/01/11 09:32:32  joergr
 * Removed method 'getMinMaxValues()' in class 'DicomImage'.
 *
 * Revision 1.6  1998/12/23 11:33:08  joergr
 * Corrected some typos and formatting.
 *
 * Revision 1.5  1998/12/22 14:03:53  joergr
 * Changed parameter declaration to avoid compiler warnings (hide parameter
 * name).
 *
 * Revision 1.4  1998/12/16 16:29:04  joergr

 * Added methods to add and remove additional overlay planes (still untested).
 *
 * Revision 1.2  1998/11/30 12:24:07  joergr
 * Added const type qualifier to some parameters to avoid errors with MSVC5
 * (couldn't create instance of abstract class).
 *
 * Revision 1.1  1998/11/27 15:06:08  joergr
 * Added copyright message.
 * Added methods and constructors for flipping and rotating, changed for
 * scaling and clipping.
 * Added method to directly create java AWT bitmaps.
 * Renamed variable 'Status' to 'ImageStatus' because of possible conflicts
 * with X windows systems.
 * Added method to detach pixel data if it is no longer needed.
 * Added methods to support presentation LUTs and shapes.
 *
 * Revision 1.6  1998/07/01 08:39:21  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 14:53:16  joergr
