Image-Only PDF Files
PDF Professional with its integrated OCR capability allows the conversion of image-only PDF files or PDF files that have a mixture of image-only and text-layer pages, into a selected target application. Image-only PDF files are typically created by scanning documents without using an OCR software (e.g. OmniPage).
An icon in the top-right corner of the PDF Converter Assistant Preview panel informs you about each page as it is displayed:
A text layer was detected for this page.
This page is image-only.
Navigate through all pages in the document. If you see both icons, or if the image-only icon displays for all pages, then instruct the program how to handle image-only pages under Processing Options on all the four processing panels (Standard Document, Legal, Spreadsheet and Form). For details, see Standard Document.
