It should. Could you do me a favour. Capture the data from mqtt and put in in an inject (or separate file) and send me your flow?
I won't have time at the moment but I'd like to see what's going on.
Ta.
Edit...
Post it as an issue if you don't mind.

Hi all,
significant updates to node-red-contrib-image-tools
Many fixes and improvements (and latest + greatest version of Jimp / zxing) but in particular the barcode decoding now supports may more formats...
Demo...
Unfortunately, this is a breaking change - so anyone using the old "2D Barcode Decode" node - please read below...
IMPORTANT - Breaking changes in V1
Version 1 has breaking change ~ vs ~ V0.x versions.
Existing flows using the "2D Barcode Decode" node will need to be modified. The easy way of fixing this is to delete any "2D Barchode Decode" & deploy, then update the node, then re-add the new "Barcode Decode" nodes.
Alternatively, you can avoid this issue by performing the following steps...
Upgrade node-red-contrib-image-tools
Stop node-red
Make a bakup of your flow.json file
Opening your flow.json file in a text editor
Search / replace all instances of
"type":"2D Barcode Decoder"with"type":"Barcode Decoder"Save and close your flow file
Start node-red
sorry folks but I have to break eggs to make the omelette.

Another update. Added UI options to the Barcode Decoder node to simplify user operation
This serves as both a visual clue (of supported formats) and simplifies operation.
Other updates...
- dont throw error when barcode not found
- better visual clues (improved node status)
- documentation update
- better defaults (faster barcode decoding)

This is really nice. I installed it and it worked right away!
Is it possible to display the image on the Dashboard group?
Thanks,

Yes.
See this post as an example...
It worked like a charm!
