ABBYY FineReader Engine ABBYY FineReader Engine

The most comprehensive OCR SDK for software developers

Integrate AI-powered OCR features into your applications.

Image import and document scanning

Providing high flexibility for image input, ABBYY FineReader Engine can receive images from many sources.

Scanning via TWAIN or WIA interface is a common way to directly convert paper documents – however, photographing documents by smartphones or tablets is an increasingly popular way for document input, especially in by companies with mobile workforce.

Already saved images, such as digital archives in TIFF or JPEG formats, can be easily imported.  Even photos from industrial cameras as used within machine vision projects for test automation, can be imported and subsequently processed. For business areas requiring high security standards, files can be loaded directly from memory without saving them to the disk first.

Document scanning APIs

With its powerful document scanning options, ABBYY FineReader Engine enables flexible management of the scanning process and provides access to the individual scanning parameters, such as brightness, color settings, resolution, image size, duplex scanning, pause between pages setup and more.

Scanning API features
  • Extended access to scan settings, including access to scan source capabilities
  • Filtration of scan sources by available user interfaces or scan API types (TWAIN, WIA)
  • Ability to specify compression type of scanned images
