QR.cpp

owing configuration: 
ImageScanner scanner;
scanner.set_config(ZBAR_QRCODE, ZBAR_CFG_ENABLE, 1);

But using this Zbar configuration still it decodes both QRCode and barcodes data.I am getting Decoded Data type as EAN-13 and QR-Code.

How I can configure Zbar sccanner properly so it decodes only QR-Code Data type?
