title: Raw response of a image/png resonpse
body: <p>I am getting a response body with raw response, which is supposed to respresent a png image. My question is how to decode this and make it a renderable.</p>
  
  <p>PS: when I am use postman to test this, I realized that Postman can render this raw string, and I am wondering how it does it.</p>
