NAME
       qgssvg -	convert	QGIS colour-ramps to SVG gradients.

SYNOPSIS

       qgssvg [-h] [-o path] [-v] [-V] path

DESCRIPTION
       The qgssvg program converts QGIS	colour-ramps to	the SVG	format.	Unlike
       most of the other file formats handled by the cptutils package, QGIS
       ramps may contain multiple gradients and	all of the input gradients
       will be converted to gradients in the output file. One can then use
       svgx(1) to extract single gradients and/or convert them to other
       formats.

       Atypically, the path to the input QGIS colour ramp is required, but the
       program will write to stdout if the --output option is not specified.

       At present, only	colour-ramps of	type gradient can be converted (so
       version 2 preset	ramps will be skipped),	similarly those	gradients
       which have the discrete attribute set true, but this restriction	will
       hopefully be lifted in a	later version.

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.

       -h, --help
	   Brief help.

       -o, --output path
	   Write the output to path, rather than stdout.

       -v, --verbose
	   Verbose operation.

       -V, --version
	   Version information.

EXAMPLE
       Convert a QGIS colour-ramp, foo.qgs, to a set of	GIMP gradients:

	   qgssvg -v -o	tmp.svg	foo.qgs
	   svggimp -v -a tmp.svg
