Not able to read a QR code

I have a PNG file that has a big QR code in the center of the image and some text below it. is not able to decode the barcode. I can email the image if required.

The problem are the many white pixels within the black area of the qr code.
If you resize the image to 30 percent of the original size than the decoding is successful.

Don't use a pre-binarized, b&w image. Use a grayscale image instead. zxing will use a binarizer
which works better with the decoding process.
