6 cptsvg - convert GMT colour palette tables (cpt) to SVG gradients.
7
9 cptsvg [-g geometry] [-h] [-o file] [-p] [-v] [-V] [file]
10
12 The cptsvg utility converts the colour palette table (cpt) files used
13 by GMT(1) to the gradients in the Scalar Vector Graphics (SVG) format.
14
15 The program will read from stdin if a file is not specified as the
16 final argument, and write to stdout if the -o option is not specified.
17
18 The output is formatted for machines to read, rather than humans. A
19 post-processor such as tidy(1) could be used in the latter case.
20
22 --backtrace-file path
23 Specify a file to which to write a formatted backtrace. The file
24 will only be created if there is a backtrace created, typically
25 when an error occurs.
26
27 --backtrace-format format
28 Specify the format of the backtrace written to the files specified
29 by --backtrace-file, one of plain, xml or json.
30
31 -g, --geometry widthxheight
32 Specify the size of the SVG preview in pixels.
33
34 -h, --help
35 Brief help.
36
37 -o, --output file
38 Write the output to file, rather than stdout.
