cptclip - extract a sub-table from a GMT colour palette table (cpt).
min/max [-h] [-o file] [-s] [-v] [-V] [file]
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.
Note that much of the functionality of this program is included in recent versions of the GMT program makecpt(1).
- Brief help.
-o, --output file
- Write the output to file, rather than stdout.
-R, --range min/max
- The (z) range of the output, or the segments if the -s switch is also given.
- The min and max arguments of the -R switch are interpreted as the segment numbers (starting at one).
- Verbose operation.
- Version information.
Extract the table with z-range from 2.5 to 5:
cptclip -v -o new.cpt -R 2.5/5 old.cpt
Extract the table with the first 5 segments:
cptclip -v -s -o new.cpt -R 1/5 old.cpt
