I have drawn a image on canvas using jcanvas drawImage method and this image is a layer
//Js part
$('canvas').drawImage({
source: 'js/BN44094.jpg',
layer: true,
x: 0, y: 0,
width: 800,
height: 400,
name: 'backImage',
fromCenter: false
});
//Html Part
<canvas id="canvas" width=800 height=400></canvas>
I want to apply instagram like image filters on this image, can some one guide me with this??
