NAME
       cptcat -	concatenate GMT	colour palette tables.

SYNOPSIS
       cptcat [-h] [-o file] [-v] [-V] file...

DESCRIPTION
       The cptcat utility concatenates two or more GMT colour palette table
       (cpt) files. The	mandatory file arguments specify the input files which
       may be specified	in any order. However, when sorted, the	maximum
       (z-value) of the	lower file should equal	the minimum of the upper file;
       files can be modified with the makecpt(1) utility to be in this form.

       The background colour will be taken from	that of	the lower (or lowest)
       file, and the forground from that of the	upper.

       The program will	write to stdout	if the -o option is not	specified.

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.

       -v, --verbose
	   Verbose operation.

       -V, --version
	   Version information.

EXAMPLES
       Create a	cpt-file topobath.cpt from topo.cpt and	bath.cpt

	   cptcat -v -o	topobath.cpt topo.cpt bath.cpt
