dcmmklut [options] dcmimg-out
The LUT data can be derived from the shape of a gamma curve (default for the gamma factor is 1) or imported from a file (currently the MAP format from Ulead's PhotoImpact and a simple text format are supported). The input and output width of the LUT can also be specified in the range allowed by the DICOM standard. The interpolation of the input range is done by a polynomial curve fitting algorithm.
In addition to the DICOM output file the LUT data can also be exported to a tabbed text file which allows the easy visualization of the curves with a common spread sheet application (e.g. Microsoft Excel).

Command line options are distinguished from parameters by a leading '+' or '-' sign, respectively. Usually, order and position of command line options are arbitrary (i.e. they can appear anywhere). However, if options are mutually exclusive the rightmost appearance is used. This behaviour conforms to the standard evaluation rules of common Unix shells.
In addition, one or more command files can be specified using an '@' sign as a prefix to the filename (e.g. @command.txt). Such a command argument is replaced by the content of the corresponding text file (multiple whitespaces are treated as a single separator) prior to any further evaluation. Please note that a command file cannot contain another command file. This simple but effective approach allows to summarize common combinations of options/parameters and avoids longish and confusing command lines (an example is provided in file share/data/dumppat.txt).
The default behaviour should be preferred and the DCMDICTPATH environment variable only used when alternative data dictionaries are required. The DCMDICTPATH environment variable has the same format as the Unix shell PATH variable in that a colon (":") separates entries. The data dictionary code will attempt to load each file specified in the DCMDICTPATH environment variable. It is an error if no data dictionary can be loaded.
