OCR Module
OCR Module

The new Amyuni OCR Module is introduced with the release of version 4.5 of the Amyuni PDF Components.

The OCR module enables developers to:

- Convert image based or non-searchable PDF documents into searchable PDFs
- Create searchable PDF documents out of various image formats such as multi-page TIFF, JPEG or PNG while applying text recognition on the images
- Compress image based PDF documents using high compression JBIG2 or more standard CCITT, JPEG and PNG compression formats

The OCR module can be either licensed independently of our other PDF Components or as an add-on to existing licenses.

The Amyuni OCR module is based on the Tesseract Open Source project with the Amyuni PDF technology being used to process and create the PDF documents. The Tesseract library provides high reliability at a low cost and avoids developers the annoyances related to licensing commercial OCR tools which are often licensed on a per-page basis or at a ridiculously high cost to the developer.
