15 \section description DESCRIPTION
16 
17 Command line program that converts VeriLUM file with characteristic curve data
18 (\e CCx_xx.dat) to a format used for the Barten transformation in this toolkit.
19 VeriLUM is a calibration package from ImageSmiths consisting of a photometer
20 (with serial RS232 connector) and a Windows NT software.

32 \section notes NOTES
33 
34 The output file describing the characteristic curve of a display system
35 (monitor) is a simple text file. Lines starting with a '#' are treated as
36 comments and therefore skipped as well as blank lines. This conversion
37 program creates such a file automatically (including some comment lines) by
38 transforming the information stored in the VeriLUM file. The number following
39 the magic word 'max' defines the maximum DDL value (e.g. 255 for 8 bit
40 displays). This definition is required before the luminance data can be
41 defined. Optionally the ambient light value can be specified in this file
42 too. The floating point value (in candela per square meter) must follow the
43 word 'amb'. Finally the luminance values are defined for each corresponding
44 DDL (device driving level) value. The entries do not necessarily have to be
45 ordered or complete, i.e. there can be less than 'max' + 1 entries. Missing
46 values are calculated by cubic spline interpolation.

49 Barten's model (including GSDF).
