Colours are the deeds of light; its deeds and sufferings: thus considered we may expect from them some explanation respecting light itself.
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-filepath-
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-formatformat-
Specify the
formatof the backtrace written to the files specified by--backtrace-file, one ofplain,xmlorjson. --comments-readpath-
Read the comments from the specified
pathand add them to the output gradient.The format is custom XML which should be fairly easy to generate, see the output of
--comments-writefor examples. --comments-writepath-
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,--geometrywidthxheight-
Specify the size of the SVG preview in pixels.
-h,--help-
Brief help.
--hinge-active-
If the input cpt has a
SOFT_HINGEdirective, 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,--outputpath-
Write the output to
path, rather thanstdout. -p,--preview-
Include a preview in the SVG output. See also the
--geometryoption. -v,--verbose-
Verbose operation.
-V,--version-
Version information.
