How to do perspective view with html5 canvas

Question

I would like to make an image into skewed/perspective/rotated in html5 canvas. The image below is exactly what I would want to do.

I have this code to use transformations in canvas but I cant make heads or tails with it. Could someone help me?

Also I only want this to be done in HTML5 Canvas not css.

var cs = Math.cos(angle1), sn = Math.sin(angle1);
var h = Math.cos(angle2);

var a = 100*cs, b = -100*sn, c = 200;
var d = h*100*sn, e = h*100*cs, f = 200;

ctx.setTransform(a, d, b, e, c, f);

Answer 1

Unfortunately it isn't possible to use the canvas context setTransform method to perform perspective transformations (you are limited to translate, scale, rotate and skew).

However, depending on your use-case, you may be able to fake it:
