Description

Detects a barcode.
We use zxing library internally and can only detect what this library handles.
Internally all images are converted to grayscale. For you getting image, it's very important to get a sharp image.
You may need to rotate or crop the image before sending into this method.

Leave some white space around as some decoders don't want to start with black frame on the edge. The barcodes generated with Barcode.Generate often don't read as they have too little resolution (e.g. scale up by 3x) and no white border around (e.g. add 5 pixels).

If special characters or umlauts are not recognized correct, you may have a wrong encoding. Most modern apps use UTF8 for encoding.
