npm-icon-gen

Generate an icon files from the SVG or PNG files.

Node.js requirements

This module depends on svg2png. Therefore we need Node v6 or later. The following is a quotation from README of svg2png.

svg2png uses the latest in ES2015 features, and as such requires a recent version of Node.js. Only the 6.x series onward is supported.

Supported the output format of the icon are following.

Platform	Icon
Windows	app.ico or specified name.
macOS	app.icns or specified name.
Favicon	favicon.ico and favicon-XX.png.

Installation

$ npm install icon-gen

Usage

SVG

SVG files are rendering to PNG file in svg2png. Rendering files is output to a temporary directory of the each OS.

Rendering of svg2png is run by phantomjs. Please use the PNG directory If the rendering quality there is a problem.

const icongen = require('icon-gen');

const options = {
  report: true,
  names: {
    ico: 'foo',
    icns: 'bar'
  }
};

icongen('./sample.svg', './dist', options)
.then((results) => {
  console.log(results)
})
.catch((err) => {
  console.error(err)
});
