*
* Revision 1.15 1999/04/29 09:20:01 joergr
* Removed color related image files from public toolkit part.
*

* Removed support for pastel color output from public DCMTK part.
*
* Revision 1.13 1999/04/28 14:51:44 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).
* Introduced new scheme for the debug level variable: now each level can be
* set separately (there is no "include" relationship).
*
* Revision 1.12 1999/03/24 17:20:14 joergr
* Added/Modified comments and formatting.
*
* Revision 1.11 1999/03/02 12:03:52 joergr
* Corrected bug in output routine of monochrome pixel data (wrong scaling when
* Barten transformation and windowing are active).
*
* Revision 1.10 1999/02/28 16:41:01 joergr
* Corrected bug: the output bits for bitmaps shutters were inverted (this was
* done due to an error in the used test images).
*
* Revision 1.9 1999/02/11 16:40:19 joergr
* Added routine to check whether particular grayscale values are unused in
* the output data.
* Removed two small memory leaks reported by dmalloc library.
*
* Revision 1.8 1999/02/05 16:44:52 joergr
* Corrected calculation of DDL value for bitmaps shutters (overlays).
*
* Revision 1.7 1999/02/05 15:13:36 joergr
* Added conversion P-Value to DDL when display function is absent.
*
* Revision 1.6 1999/02/03 17:32:43 joergr
* Added optimization LUT to transform pixel data.
* Added support for calibration according to Barten transformation (incl.
* a DISPLAY file describing the monitor characteristic).
*
* Revision 1.5 1999/01/20 15:11:05 joergr
* Replaced invocation of getCount() by member variable Count where possible.
* Added new output method to fill external memory buffer with rendered pixel
* data.
* Added new overlay plane mode for bitmap shutters.
* Added optimization to modality and VOI transformation (using additional
* LUTs).
*
* Revision 1.4 1998/12/23 12:40:01 joergr
* Removed unused parameter (BitsPerSample).
*
* Revision 1.3 1998/12/22 14:32:49 joergr
* Improved implementation of presentation LUT application (and other gray
* scale transformations). Tested with ECR test images from David Clunie.
*
* Revision 1.2 1998/12/14 17:25:55 joergr
* Added support for correct scaling of input/output values for grayscale
* transformations.
*
* Revision 1.1 1998/11/27 15:29:53 joergr
* Added copyright message.
* Introduced global debug level for dcmimage module to control error output.
* Corrected bug in VOI LUT transformation method.
* Changed behaviour: now window width of 0 is valid and negative width
* is invalid.
*
* Revision 1.6 1998/07/01 08:39:24 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 14:53:22 joergr
* Added CVS/RCS header to each file.
