Description

How would you describe the priority of this documentation request

Would be nice

Describe the future/missing documentation

i am trying to use nv-ingest in the rag blueprint and i have come across an issue:
when the extract method is pdfium, there is no problem ingesting pdfs but i can not ingest images
when the extract method is None, i can ingest pdfs and images as well but pdfs which are scanned images fail

so what happens when extract method is None?

Research direction

Start with the linked nv-ingest Python API quick-start section and compare the documented behavior of the pdfium and None extract methods. Done means clearly documenting how extract=None handles PDFs, images, and scanned-image PDFs, including the reported failure case.
