convert scanned pdf into searchable pdf - Alfresco Community 5.2

[anuradha1]

Hi,

I am using alfresco for a long time. I scanned around 100,000 documents & uploaded into alfresco. But suddenly i faced a problem because it can't be read using it's content. If i scanned a document using a scanner having ocr then it can be. But, i don't have ocr on every scanner so i need to integrate OCR module into alfresco. I tried tesseract ocr & simple ocr, but both did not worked.

1. If anyone knows, plz tell me another way to do this or correct way to integrate tesseract-ocr or simple-ocr
2. I need to convert all uploaded document into searchable pdf also.

Thanks

Hi anuradha madhushani

Do you know this addon?

GitHub - keensoft/alfresco-simple-ocr: Simple OCR action for Alfresco 

You can configure a rule which it executes the OCR action from this addon.

I tried it. but not working. i am having CentOS 7 repository. I think pdfsandwitch not supported for this repository. OCRmyPDF also not installed i can't find whether its supported to  CentOS 7 or not. What can i do??

Thank you.

You can take this as base: 

https://github.com/keensoft/alfresco-simple-ocr/blob/master/docker/pdfsandwich-1.6-centos-7/Dockerfi...

Thank you for all who helps to me. I did it with simple-ocr for my Linux installation. But now i need to do the same with an alfresco windows installation. Anyone knows a way to do that??

Any help will be appreciated.

Thank you.
