cptsvg - Man Page
convert GMT colour palette tables (cpt) to SVG gradients.
Synopsis
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 simply a plain text multi-line document without any comment delimiters (those will be added by the program).
- --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
