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

SYNOPSIS

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

DESCRIPTION
       The cptsvg utility converts the colour palette table (cpt) files	used
       by GMT 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 --output option is not
       specified.

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.

       --comments-read path
	   Read	the comments from the specified	path and add them to the
	   output gradient.

	   The format is custom	XML which should be fairly easy	to generate,
	   see the output of --comments-write for examples.

       --comments-write	path
	   Write the comments in the input to the specified path.

       --comments-retain
	   Use the comments in the input file as the comments for the output
	   file.

       --comments-generate
	   Create a comment with summary data (the date	of creation, name and
	   version of the cptutils package) in the output file.

       -g, --geometry widthxheight
	   Specify the size of the SVG preview in pixels.

       -h, --help
	   Brief help.

       --hinge-active
	   If the input	cpt has	a SOFT_HINGE directive,	then activate that
	   hinge (resulting in independent scaling of the two halves of	the
	   gradient either side	of the hinge).

	   If the input	does not have such a directive,	then this option has
	   no effect.

       -o, --output path
	   Write the output to path, 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.

EXAMPLE
       Create an SVG file from CPT:

	   cptsvg -v -o	foo.svg	foo.cpt
