Object {imageFormat: "image/jpeg", imageB64: "/9j/4AAQ...="}
imageB64: "/9j/4AAQSkZJRgABAQAAAQABAAD/2wBD..."
imageFormat: "image/jpeg"

I have an image object as above. I printed it out using 

console.log(result);

It is pretty obvious that it is in base64.

What I want to do is to save this image onto my file system so that i can analyse it. I want to be able to find out the quality and size of this image as it was taken by my webcam and cropped.

  • @PawełGłowacz So am I supposed to convert it into a blob object before I can save it? – Ming Jin Jul 15 '16 at 08:30
  • Sounds valid to me. Of course you can make image from this base64 and hide in some div and use 3rd party like html2canvas check this answer: http://stackoverflow.com/questions/33668608/generate-an-image-of-a-div-and-save-as/33669243#33669243 – Paweł Głowacz Jul 15 '16 at 08:35
  • @PawełGłowacz I keep getting an error, it says the download has failed and that there is no file, I did the following. `
    downloadURI(result, "myImage.jpeg");
    ` `

    function downloadURI(uri, name) {  
    var link = document.createElement("a");
    link.download = name;
    link.href = uri;
    link.click();
    //after creating link you should delete dynamic link  
    //clearDynamicLink(link);  
}
