NAME

6       cptcat - concatenate GMT colour palette tables.
7

SYNOPSIS

9       cptcat [-h] [-o file] [-v] [-V] file...
10

DESCRIPTION

12       The cptcat utility concatenates two or more GMT colour palette table
13       (cpt) files. The mandatory file arguments specify the input files which
14       may be specified in any order. However, when sorted, the maximum
15       (z-value) of the lower file should equal the minimum of the upper file;
16       files can be modified with the makecpt(1) utility to be in this form.
17
18       The background colour will be taken from that of the lower (or lowest)
19       file, and the forground from that of the upper.
20
21       The program will write to stdout if the -o option is not specified.
22

OPTIONS

24       --backtrace-file path
25           Specify a file to which to write a formatted backtrace. The file
26           will only be created if there is a backtrace created, typically
27           when an error occurs.
28
29       --backtrace-format format
30           Specify the format of the backtrace written to the files specified
31           by --backtrace-file, one of plain, xml or json.
32
33       -h, --help
34           Brief help.
35
36       -o, --output file
37           Write the output to file, rather than stdout.
38
39       -v, --verbose
40           Verbose operation.
41
42       -V, --version
43           Version information.
