NAME
gplcpt – convert GIMP colour palette (gpl) to GMT colour palette table (cpt).
SYNOPSIS
-
gplcpt[-brgb] [-f rgb] [-h] [-n rgb] [-o file] [-v] [-V] [file]
DESCRIPTION
gplcpt 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.
