getRawBytes returns null

I am trying to get the bytes of barcodes but it returns null.

The comment says that it returns raw bytes encoded by the barcode, if applicable, otherwise null. I wonder when it is applicable.

Can you attach the barcode?

The library is able to correctly read that given Code-39, I manually made a unit-test with that image (I cropped it though). Do you use a camera to scan that? Or the image file? It is quite a complex code...

I need to read the image file. The content of the PDF417 is stored as bytes so I need to use getRawBytes.

If I use a PDF417Reader instead of a MultiFormatReader I can read and recognize it
