Name

cptcat — concatenate GMT colour palette tables.

Synopsis

cptcat [-h ] [-o file ] [-v ] [-V ] file...

DESCRIPTION

The 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 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.
-h, --help: Brief help.
-o, --output file: Write the output to file, rather than stdout.
-v, --verbose: Verbose operation.
-V, --version: Version information.

EXAMPLES

Create a cpt-file topobath.cpt from topo.cpt and bath.cpt

cptcat -v -o topobath.cpt topo.cpt bath.cpt
