NAME
       cptclip - extract a sub-table from a GMT	colour palette table (cpt).

SYNOPSIS
       cptclip -R min/max [-h] [-o file] [-s] [-v] [-V]	[file]

DESCRIPTION
       The cptclip utility extracts a sub-table	from a cpt format file.	The
       arguments to the	mandatory -R option, min/max, are interpreted as the
       (z) limits of the output	unless the -s switch is	specified, in which
       case they are the segment numbers.

       The program will	read from stdin	if a file is not specified as the
       final argument, and write to stdout if the -o option is not specified.

       Note that much of the functionality of this program is included in
       recent versions of the GMT program makecpt(1).

OPTIONS
       --backtrace-file	path
	   Specify a file to which to write a formatted	backtrace. The file
	   will	only be	created	if there is a backtrace	created, typically
	   when	an error occurs.

       --backtrace-format format
	   Specify the format of the backtrace written to the files specified
	   by --backtrace-file,	one of plain, xml or json.

       -h, --help
	   Brief help.

       -o, --output file
	   Write the output to file, rather than stdout.

       -R, --range min/max
	   The (z) range of the	output,	or the segments	if the -s switch is
	   also	given.

       -s, --segments
	   The min and max arguments of	the -R switch are interpreted as the
	   segment numbers (starting at	one).

       -v, --verbose
	   Verbose operation.

       -V, --version
	   Version information.

EXAMPLES
       Extract the table with z-range from 2.5 to 5:

	   cptclip -v -o new.cpt -R 2.5/5 old.cpt

       Extract the table with the first	5 segments:

	   cptclip -v -s -o new.cpt -R 1/5 old.cpt
