contentCrawler adheres to all security settings and won’t create a copy of the PDF with added text layer unless the security settings allow for this. The newly-created version of the PDF inherits all the same PDF security settings as the original if allowed.
If the security settings on a PDF prevent it from opening, the Assess process flags it as ‘unable to assess’ or ‘unable to process’ for those that contentCrawler could not read or update with OCR text.
