Document Scanning APIs in Windows

  • TWAIN interface (including ADF support and manual input feeding)
  • FineReader document scanning UI
With its powerful document scanning software tools, ABBYY FineReader Engine 12 enables flexible management of scanning parameters, such as: brightness, colority, resolution, image size, duplex scanning, pause between pages setup and more. For OCR purposes, the best resolutions lie in the range of 200-400 dpi. The choice of resolution depends on the quality of the paper original, the size of the font and other factors. For more details, please see the description of the Scanning scenario.
