Hi, in order to make code more readable and importable it is important to surround your code with three backticks
```
like this
```

You can edit and correct your post by clicking the pencil icon.

See this post for more details - How to share code or flow json

Also tell us which node you are using, node-red-contrib-something probably.

unfortunately the decoder in "image-tools" is not the greatest & needs better imagery than you have provided. You might be able to use the various "image tools" functions (like crop, contrast, brightness, rotation, re-sample, slight gaussian blur etc) to make it readable before sendinr to the decoder

That said, to prove it is actually working on your system (and it s not something else), import the demo (CTRL+I --> examples)

Do the demos work?
