Phonegap 3.0.0: BarcodeScanner Plugin

But it seems like it cannot scan Qr Code. Here is the screen shot from phone:

enter image description here

I have tried scanning a barcode image and it works fine. But not with QR images.
Any idea?

EDIT 

    var scanner = cordova.require("com.phonegap.plugins.barcodescanner.barcodescanner");

    scanner.scan(
        function (result) {
            alert("We got a barcode\n" +
                "Result: " + result.text + "\n" +
                "Format: " + result.format + "\n" +
                "Cancelled: " + result.cancelled);
        },
        function (error) {
            alert("Scanning failed: " + error);
        }
    );

DuuhhH!!! The problem was the QR image, it has no margin as Sean Owen said.

    It's fine to me if you don't like the question and decide to close it. But can you please give some reason? I've been spending hours solving my problem. – fiberOptics Oct 09 '14 at 16:19

    That QR code does not have a margin, which is probably why it won't scan. – Sean Owen Oct 09 '14 at 16:25

    OMG, you're right. The QR code I used was generated from our api service. Basically it has no margin. Didn't know it was important. Thanks!!!! – fiberOptics Oct 09 '14 at 16:31
  • what about other QR image? I see QR Scanner app (in Apple store) can scan every QR image. – Tran Trung Hieu Aug 10 '16 at 10:25

Copying from my comment as it seems to be the answer: That QR code does not have a margin, which is probably why it won't scan.
