gplcpt - Man Page
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.
