Node.JS Binding for LibRSVG
LibRSVG is a SVG rendering library, which parses SVG files and renders them in various formats. The formats include:
- PNG
- SVG
- Raw memory buffer image
Basic Usage
Here is a simple example. Look in index.js for more documentation.
var Rsvg = require('rsvg').Rsvg;
var fs = require('fs');
// Create SVG render instance.
var svg = new Rsvg();
// When finishing reading SVG, render and save as PNG image.
svg.on('finish', function() {
console.log('SVG width: ' + svg.width);
console.log('SVG height: ' + svg.height);
fs.writeFile('tiger.png', svg.render({
format: 'png',
width: 600,
height: 400
}).data);
});
// Stream SVG file into render instance.
fs.createReadStream('tiger.svg').pipe(svg);
