The CAS Document Conversion Module works as follows when processing Adobe PDF files with security settings:
The CAS Document Conversion Module will respect the no-copy option of a PDF. That is, if a PDF publishing application has a no-copy option (which prohibits the copying or extraction of text within the PDF), the Document Conversion Module will not extract text from that PDF.
The CAS Document Conversion Module does not support text extraction from password-protected files.
The CAS Document Conversion Module does not support text extraction from PDFs with encrypted content.
To extract the text from these types of PDFs, you must re-create them without setting the appropriate security option.
In addition, text added with the Sticky Note tool is not extracted.
