6 dconvlum - Convert VeriLUM files to DCMTK display files
7
10 dconvlum in-file out-file [ambient]
11
13 Command line program that converts VeriLUM file with characteristic
14 curve data (CCx_xx.dat) to a format used for the Barten transformation
15 in this toolkit. VeriLUM is a calibration package from ImageSmiths
16 consisting of a photometer (with serial RS232 connector) and a Windows
17 NT software.

20 in-file VeriLUM characteristic curve file to be converted
21 out-file DCMTK display file to be written
23 ambient ambient light (cd/m^2, floating point value)

27 The output file describing the characteristic curve of a display system
28 (monitor) is a simple text file. Lines starting with a '#' are treated
29 as comments and therefore skipped as well as blank lines. This
30 conversion program creates such a file automatically (including some
31 comment lines) by transforming the information stored in the VeriLUM
32 file. The number following the magic word 'max' defines the maximum DDL
33 value (e.g. 255 for 8 bit displays). This definition is required before
34 the luminance data can be defined. Optionally the ambient light value
35 can be specified in this file too. The floating point value (in candela
36 per square meter) must follow the word 'amb'. Finally the luminance
37 values are defined for each corresponding DDL (digital driving level)
38 value. The entries do not necessarily have to be ordered or complete,
39 i.e. there can be less than 'max' + 1 entries. Missing values are
40 calculated by cubic spline interpolation.
41 See DICOM standard part 14 for more details on display calibration and
43 Barten's model (including GSDF).
