GPLCPT(1) User commands GPLCPT(1) 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.
