Name

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
