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.

-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
