GD bindings for Node.js

GD graphic library bindings for Node.js supporting asynchronous I/O written in C/C++.

Tested with Node v0.4.6 & v0.6.6 (by Dudochkin Victor blacksmith@gogoo.ru)

Install:

Using npm

npm install gd

From sources

  1. go to the directory with GD (this library :) )

  2. execute node-waf configure build

  3. Put it in node_modules.

Using GD

app.js:

var fs   = require('fs');
var path = require('path');
var gd   = require('gd');
var source = './test.png';
var target = './test.thumb.png';

if (path.exists(target)) fs.unlink(target);

gd.openPng(
source,
function(png, path) {
	if(png) {
		var w = Math.floor(png.width/2), h = Math.floor(png.height/2);
		var target_png = gd.createTrueColor(w, h);

		png.copyResampled(target_png,0,0,0,0,w,h,png.width,png.height);
		target_png.savePng(target, 1, gd.noop);
	}
}
);

That's all folks!
