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 (device 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).
