Canvas = require('canvas');
var ht = require('https');
http.createServer(function (req, res) {
dr();
function dr()
{
fs.readFile(__dirname + '/temp.jpg', function(err, data) {
if (err) throw err;
var img = new Canvas.Image; // Create a new Image
img.src = data;
var canvas = new Canvas(img.width, img.height,'pdf');
var ctx = canvas.getContext('2d');
ctx.drawImage(img, 0, 0, img.width / 4, img.height / 4);
res.writeHead(200, {'content-type' : 'application/pdf'});
canvas.toDataURL('application/pdf', function(err, str){

This code working for me.
var http = require('http'), fs = require('fs'),
Canvas = require('canvas');
var ht = require('https');
http.createServer(function (req, res) {
dr();
function dr()
{
fs.readFile(__dirname + '/temp.jpg', function(err, data) {
if (err) throw err;
var img = new Canvas.Image; // Create a new Image
img.src = data;
var canvas = new Canvas(img.width, img.height, 'pdf');
var ctx = canvas.getContext('2d');
ctx.drawImage(img, 0, 0, img.width / 4, img.height / 4);
res.writeHead(200, {'content-type' : 'application/pdf'});
res.write( canvas.toBuffer() );
res.end();
});
}
}).listen(8124);
