NAME

6       gplcpt - convert GIMP colour palette (gpl) to GMT colour palette table
7       (cpt).
8

SYNOPSIS

10       gplcpt [-b rgb] [-f rgb] [-h] [-n rgb] [-o file] [-v] [-V] [file]
11

DESCRIPTION

13       The gplcpt program converts GIMP(1) colour palette (gpl) files to the
14       GMT(1) colour palette table (cpt) format. The output is a piecewise
15       constant (step or discrete) gradient. One could use cptcont(1) program
16       to convert the output to a continuous cpt file if so desired.
17
18       The program will read from stdin if a file is not specified as the
19       final argument, and write to stdout if the -o option is not specified.

OPTIONS

22       In the following, all rgb specifications should be of the form
23       red/green/blue where the colour components are integers in the range 0
24       to 255.
25
26       -b, --background rgb
27           Set the background colour of the output.
28
29       --backtrace-file path
30           Specify a file to which to write a formatted backtrace. The file
31           will only be created if there is a backtrace created, typically
32           when an error occurs.
33
34       --backtrace-format format
35           Specify the format of the backtrace written to the files specified
36           by --backtrace-file, one of plain, xml or json.
37
38       -f, --foreground rgb
39           Set the foreground colour of the output.

42           Brief help.
43
44       -n, --nan rgb
45           Set the NaN (no data) colour of the output.
46
47       -o, --output file
48           Write the output to file, rather than stdout.
49
50       -v, --verbose
51           Verbose operation.
