Loading PDF files
There are three PDF options in the Process panel (in Workflow Assistant in the Load Files dialog box): Open as Image, Use tags and Use PDF fonts. For these options to take effect, reload the PDF file with the required option selected.
If you want to load a password protected PDF file through the Workflow Assistant, you have to type in the password in the Load Files dialog box.
A separate facility in OmniPage Professional allows image-only PDF files, or files with image-only pages or portions, to be made fully searchable. See eDiscovery Assistant for Searchable PDF.
