body: <p>Goodnight</p>
  
  <p>I need your help. I have a string like this "data: application / octet-stream; base64, ...." result of sample capture from digital person web application SDK 3 and want to convert this string to "data: image / png; base64, ... "just to show the captured fingerprint. I don't want to save or load a file, I need after the capture display the finger image. I can easily send the wsq data to be processed to the server side</p>
