Barcode not recognized Windows 8 javascript metro application

Feb 17, 2014 at 9:37 AM

I tried the sample It was working when i picked a barcode image. But i needed the barcode to be scanned, so i tried after capturing a photo. It captures the photo, but the line:

var result = reader.decode(pixels, decoder.pixelWidth, decoder.pixelHeight, format);

always returns "null" in result.

Please let me know what went wrong, or if I am missing some thing.

The problem was that only barcode image part should be clicked. If the images contains other things too, any border etc. It wouldn't be recognised.
Also, is it possible that barcode is recognised automatically, Currently user have to click to capture the image and then the barcode is identified.
