Adobe Acrobat XI Pro: A Comprehensive Technical and Functional Analysis

2. Enhanced OCR (Optical Character Recognition)

The "Recognize Text" feature in Pro 11 was a massive leap forward. Using the ClearScan technology, it could convert scanned paper documents into fully searchable, selectable text.
