This updates brings the abilitiy to generate searchable PDF to OCR Engine2. Searchable PDF are sometimes called Sandwich PDF because they contain two layers: The original PDF and a second layer with the OCR’ed text.

This updates also improves the searchable PDF generation in general. The new searchable PDF software supports mixed format documents as input now. Mixed format documents are scans that contain both landscape and portrait pages within one scan PDF.

Since the format of the returned OCR API result (JSON) is identical for both OCR engines, you can easily switch between both engines as needed. Just change the OCREngine parameter from “1” to “2”. If you have any question about using Engine 1 or 2, please ask in our UI.Vision OCR API Forum.
