Describe the bug I'm unable to scan the data matrix which is imprinted on black surface especially on plastic box. Could you please suggest?

I don't have the exact one, but attached the similar one which I took it from web.

Mainly the one with black background - First picture DataMatrix

Please let me know. I'm using @zxing/ngx-scanner 3.0.0

There's a little bigger step you need to take for being able to decode inverted data matrix trough this component, which I think might not be possible for now. Here's an example of what we need to do: https://github.com/zxing-js/library/issues/135#issuecomment-470430181
