NAME
       dconvlum	- Convert VeriLUM files	to DCMTK display files

SYNOPSIS
       dconvlum	in-file	out-file [ambient]

DESCRIPTION
       Command	line  program  that  converts VeriLUM file with	characteristic
       curve data (CCx_xx.dat) to a format used	for the	Barten	transformation
       in  this	 toolkit.  VeriLUM  is	a calibration package from ImageSmiths
       consisting of a photometer (with	serial RS232 connector)	and a  Windows
       NT software.

PARAMETERS
       in-file	 VeriLUM characteristic	curve file to be converted

       out-file	 DCMTK display file to be written

       ambient	 ambient light (cd/m^2,	floating point value)

NOTES
       The output file describing the characteristic curve of a	display	system
       (monitor) is a simple text file.	Lines starting with a '#' are  treated
       as  comments  and  therefore  skipped  as  well	as  blank  lines. This
       conversion program creates such a file  automatically  (including  some
       comment	lines)	by  transforming the information stored	in the VeriLUM
       file. The number	following the magic word 'max' defines the maximum DDL
       value (e.g. 255 for 8 bit displays). This definition is required	before
       the luminance data can be defined. Optionally the ambient  light	 value
       can be specified	in this	file too. The floating point value (in candela
       per square meter) must follow the word  'amb'.  Finally	the  luminance
       values  are  defined for	each corresponding DDL (digital	driving	level)
       value. The entries do not necessarily have to be	ordered	 or  complete,
       i.e.  there  can	 be  less  than	 'max' + 1 entries. Missing values are
       calculated by cubic spline interpolation.

       See DICOM standard part 14 for more details on display calibration  and
       Barten's	model (including GSDF).
