Why Candidate Image is not picked up?

We provide the candidate image value in 'CandidateImageData' tag for word documents only, not for the PDF files. So, you will not be able to get the candidate image data value for a PDF file.

If you are parsing the doc/docx file and still not getting candidate image data, you can contact RChilli Support via creating a ticket at RChilli HelpDesk or sending an email at support@rchilli.com. The Support Team will assist you further.
