cytoscape-effective-area v0.2.1

cytoscape-effective-area

Description

Invoke fit/center with an effective area without changing the canvas size. (demo)

Dependencies

• Cytoscape.js ^3.2.0

Usage instructions

Download the library:

• via npm: npm install cytoscape-effective-area,
• via unpkg: https://unpkg.com/cytoscape-effective-area/dist/index.js

Import the library as appropriate for your project:

ES import:

import cytoscape from 'cytoscape';
import effectiveArea from 'cytoscape-effective-area';

cytoscape.use( effectiveArea );

CommonJS require:

let cytoscape = require('cytoscape');
let effectiveArea = require('cytoscape-effective-area');

cytoscape.use( effectiveArea ); // register extension

AMD:

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

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

API

const ea = cy.effectiveArea(() => {
  return {
    x: 100,
    y: 200,
    width: 400,
    height: 500,
  };
});

// Change effective area getter function
ea.enable(() => {
  return {
    x: 500,
    y: 100,
    width: 100,
    height: 50,
  };
})

// Disable

  return {
    x: 100,
    y: 200,
