Generate an icon files from the SVG or PNG files.
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. |
$ npm install icon-gen
SVG and PNG are automatically selected from the input path. If the path indicates a file SVG, if it is a directory it will be a PNG folder.
SVG files are rendering to PNG file in sharp. Rendering files is output to a temporary directory of the each OS.
const icongen = require('icon-gen')
icongen('./sample.svg', './icons', { report: true })
.then((results) => {
console.log(results)
})
.catch((err) => {
console.error(err)
})Stopped using svg2png because of its dependency on phantomjs, which is deprecated.
The quality of PNG generated from SVG will change, so if you need the previous results, use icon-gen v2.1.0 (old version).
$ npm install [email protected]
In the future, I may add SVG to PNG conversion by Chromium via puppeteer-core in addition to sharp.
Generate an icon files from the directory of PNG files.
const icongen = require('icon-gen')
icongen('./images', './icons', { report: true })
.then((results) => {
console.log(results)
})
.catch((err) => {
console.error(err)
})Required PNG files is below. Favicon outputs both the ICO and PNG files (see: audreyr/favicon-cheat-sheet).
