/*
* CVS/RCS Log:
* $Log: dcmdrle.cc,v $
* Revision 1.12 2005/12/08 15:40:45 meichel
* Changed include path schema for all DCMTK header files
*
* Revision 1.11 2005/12/02 09:03:52 joergr
* Added new command line option that ignores the transfer syntax specified in
* the meta header and tries to detect the transfer syntax automatically from
* the dataset.
*
* Revision 1.10 2005/11/07 17:10:19 meichel
* All tools that both read and write a DICOM file now call loadAllDataIntoMemory()
* to make sure they do not destroy a file when output = input.
*
* Revision 1.9 2005/07/26 17:08:28 meichel
* Added option to RLE decoder that allows to correctly decode images with
* incorrect byte order of byte segments (LSB instead of MSB).
*
* Revision 1.8 2005/05/26 14:52:22 meichel
* Added option --read-dataset to dcmdrle that allows to decompress RLE
* compressed DICOM objects that have been stored as dataset without meta-header.
* Such a thing should not exist since the transfer syntax cannot be reliably
* determined without meta-header, but unfortunately it does.
*
* Revision 1.7 2004/01/16 10:53:53 joergr
* Adapted type casts to new-style typecast operators defined in ofcast.h.
*
* Revision 1.6 2002/11/27 12:07:16 meichel
* Adapted module dcmdata to use of new header file ofstdinc.h
*
* Revision 1.5 2002/11/26 08:43:00 meichel
* Replaced all includes for "zlib.h" with <zlib.h>
* to avoid inclusion of zlib.h in the makefile dependencies.
*
* Revision 1.4 2002/09/23 17:52:02 joergr
* Prepared code for future support of 'config.guess' host identifiers.
*
* Revision 1.3 2002/09/23 13:50:40 joergr
* Added new command line option "--version" which prints the name and version
* number of external libraries used.
*
* Revision 1.2 2002/08/21 10:14:14 meichel
* Adapted code to new loadFile and saveFile methods, thus removing direct
* use of the DICOM stream classes.
*
* Revision 1.1 2002/06/06 14:52:32 meichel
* Initial release of the new RLE codec classes
* and the dcmcrle/dcmdrle tools in module dcmdata
*
*
