NAME
       gplcpt -	convert	GIMP colour palette (gpl) to GMT colour	palette	table
       (cpt).

SYNOPSIS
       gplcpt [-b rgb] [-f rgb]	[-h] [-n rgb] [-o file]	[-v] [-V] [file]

DESCRIPTION
       The gplcpt program converts GIMP(1) colour palette (gpl)	files to the
       GMT(1) colour palette table (cpt) format. The output is a piecewise
       constant	(step or discrete) gradient. One could use cptcont(1) program
       to convert the output to	a continuous cpt file if so desired.

       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.

OPTIONS
       In the following, all rgb specifications	should be of the form
       red/green/blue where the	colour components are integers in the range 0
       to 255.

       -b, --background	rgb
	   Set the background colour of	the output.

       --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.

       -f, --foreground	rgb
	   Set the foreground colour of	the output.

       -h, --help
	   Brief help.

       -n, --nan rgb
	   Set the NaN (no data) colour	of the output.

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

       -v, --verbose
	   Verbose operation.

       -V, --version
	   Version information.
