All you need is to use canvas . Please take a look at my example.

 var canvas = document.getElementById('canvas'), ctx = canvas.getContext('2d'); canvas.width = $('img').width(); canvas.crossOrigin = "Anonymous"; canvas.height = $('img').height(); ctx.drawImage($('img').get(0), 0, 0); ctx.font = "36pt Verdana"; $(document).on('input','#inp',function(){ //redraw image ctx.clearRect(0,0,canvas.width,canvas.height); ctx.drawImage($('img').get(0), 0, 0); //refill text ctx.fillStyle = "red"; ctx.fillText($(this).val(),40,80); }); $('button').click(function(){ console.log(ctx.getImageData(50, 50, 100, 100)); });
