cytoscape-svg

cytoscape-svg

Description

Export the current graph view as an SVG image. (demo)

Dependencies

• Cytoscape.js ^3.2.0
• canvas2svg

Usage instructions

Download the library:

• via npm: npm install cytoscape-svg,
• via bower: bower install cytoscape-svg, or
• via direct download in the repository (probably from a tag).

Import the library as appropriate for your project:

ES import:

import cytoscape from 'cytoscape';
import svg from 'cytoscape-svg';

cytoscape.use( svg );

CommonJS require:

let cytoscape = require('cytoscape');
let svg = require('cytoscape-svg');

cytoscape.use( svg ); // register extension

AMD:

require(['cytoscape', 'cytoscape-svg'], function( cytoscape, svg ){
  svg( cytoscape ); // register extension
});

Plain HTML/JS has the extension registered for you automatically, because no require() is needed.

API

cy.svg(options)

• options: the export options
  • full: Whether to export the current viewport view (false, default) or the entire graph (true).
  • scale: This value specifies a positive number that scales the size of the resultant image.
  • bg: The background color of the SVG (transparent by default).

Build targets

• npm run test : Run Mocha tests in ./test
• npm run build : Build ./src/** into cytoscape-svg.js
• npm run watch : Automatically build on changes with live reloading (N.b. you must already have an HTTP server running)
• npm run dev : Automatically build on changes with live reloading with webpack dev server
• npm run lint : Run eslint on the source

N.b. all builds use babel, so modern ES features can be used in the src.
