NAME

6       gimplut - convert GIMP gradient (ggr) files to binary lookup tables
7       (lut).
8

SYNOPSIS

10       gimplut [-h] [-o file] [-s samples] [-v] [-V] [file]
11

DESCRIPTION

13       The gimplut utility converts gradient files from the GIMP(1), the GNU
14       Image Manipulation Program, to a binary lookup table format commonly
15       used by medical imaging software; in particular the Medcon(1) package.
16
17       The LUT format consists of n red, n green and n blue bytes, interpreted
18       as integers from 0 to 255.
19
20       The program will read from stdin if a file is not specified as the
21       final argument, and 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       -s, --samples number
40           Use the specified number of samples rather than 256.
41
42       -v, --verbose
43           Verbose operation.
44
45       -V, --version
46           Version information.
47

CAVEATS

49       The alpha channel of the input is completely ignored in the output.
50
51       At some point in the future the functionality of this program will be
52       transferred to the svgx(1) program.
