Solved Multi Language OCR Support

[WiseMetalhead]

Is it possible to enable multi-language OCR support for paperless-ng?

As far as I understand, docker has variables for this. And I also found this modification.

@wisemetalhead according to this, we can enable additional languages under PAPERLESS_OCR_LANGUAGE in OCR settings options. This can be found in the paperless.conf file when you click the file manager icon of the paperless-ng app's settings in Cloudron.

Did the provided suggestion from @neurokrish solve the issue?

@nebulon @WiseMetalhead there is some more information here. Looks like there are two options, PAPERLESS_OCR_LANGUAGES and PAPERLESS_OCR_LANGUAGE. The first one determines which packages to install and the second one, which to use. The first option is missing in the paperless.conf file. May be we can add this manually and restart the app?

@neurokrish @nebulon I tried this method earlier, but it didn't work.

My paperless.conf file:

@wisemetalhead according to the docs, the PAPERLESS_OCR_LANGUAGES option should be configured in docker-compose.env and not in paperless.conf. Perhaps @nebulon can help here..

@neurokrish I have to try this here myself, since the Cloudron app package has nothing to do with their upstream docker image, the default self-hosting config docs would apply instead, so https://paperless-ng.readthedocs.io/en/latest/configuration.html?highlight=languages#ocr-settings

[neurokrish]

@nebulon then may be a standard apt-get install for additional language packs is the way to go?

May be we can install all OCR languages by default using sudo apt-get install tesseract-ocr-all as mentioned here. This way, the app has all languages installed by default and users can choose a specific language by modifying the PAPERLESS_OCR_LANGUAGE flag in paperless.conf.

@neurokrish thanks for the suggestion, at least it solved the issue for me with a deu+eng setting. The just updated package v0.7.0 has those changes.

[neurokrish]

@nebulon great! @WiseMetalhead, can you confirm that the latest update solves your issue with OCR?

[WiseMetalhead]

@neurokrish @nebulon Now it works perfectly! Thanks for the help.

@neurokrish tesseract has a Docker file and it would be nice to support Tesseract on Cloudron.
