Description

There is a PDF document (without plain text content) in which text content are scans of multiple pages.

OCR for one of the images (text of a page) fails by tika-server with activated inline OCR for PDF.

My fallback/alternate in Open Semantic ETL / Open Semantic Search using pdfimages of Debian package poppler-utils to extract the images works for all images in that PDF document).

I can not attach/upload this document here to the public because of Copyright/Classified issues, but if interested, i could send it to certain developer(s).

Following tika-server exception in result field X-TIKA:EXCEPTION:embedded_stream_exception:
