Cptsvg (1) Linux Manual Page

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

Synopsis

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.

-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.

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
