NAMEcptcat - concatenate GMT colour palette tables.SYNOPSIScptcat [-h] [-o file] [-v] [-V] file... DESCRIPTIONThe cptcat utility concatenates two or more GMT colour palette table (cpt) files. The mandatory file arguments specify the input files which may be specified in any order. However, when sorted, the maximum (z-value) of the lower file should equal the minimum of the upper file; files can be modified with the makecpt(1) utility to be in this form.The background colour will be taken from that of the lower (or lowest) file, and the forground from that of the upper. The program will write to stdout if the -o option is not specified. OPTIONS--backtrace-file pathSpecify 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.
-h, --help Brief help.
-o, --output file Write the output to file, rather than
stdout.
-v, --verbose Verbose operation.
-V, --version Version information.
