cptsvg — convert GMT colour palette tables (cpt) to SVG gradients.

Synopsis

cptsvg [-g geometry] [-h] [-o file] [-p] [-v] [-V] [file]

Description

The cptsvg utility converts the colour palette table (cpt) files used by GMT(1) to the gradients in the Scalar Vector Graphics (SVG) format.

The program will read from stdin if a file is not specified as the final argument, and write to stdout if the -o option is not specified.

The output is formatted for machines to read, rather than humans. A post-processor such as tidy(1) could be used in the latter case.

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.
-g, --geometry widthxheight
Specify the size of the SVG preview in pixels.
-h, --help
Brief help.
-o, --output file
Write the output to file, rather than stdout.
-p, --preview
Include a preview in the SVG output. See also the --geometry option.
-v, --verbose
Verbose operation.
-V, --version
Version information.

Examples

Create a machine-readable SVG file:

cptsvg -v -o new.svg old.cpt

Create a human-readable SVG file with a preview:

cptsvg -p old.cpt | tidy -xml -indent -o new.svg
