Fast TWAIN SDK Technology

LEADTOOLS Fast TWAIN intelligently analyzes the TWAIN source capabilities to find the combination of compression, transfer mode, and buffering scheme that will provide the best possible performance for the requested image type.

LEAD continues to research and develop special techniques to get the most from any TWAIN source. By analyzing available hardware capabilities, applying LEADTOOLS optimized compression technology, implementing advanced buffering techniques, and utilizing LEADTOOLS multithreaded infrastructure to process and compress data while scanning, LEADTOOLS is able to dramatically increase the speed of scanning, even when using standard TWAIN sources.

Overview of LEADTOOLS Fast TWAIN SDK Technology

  • Fast TWAIN improves the speed of TWAIN scanning operations by analyzing the TWAIN source for the best combination of settings, including:
    • Bits per pixel
    • Image compression
    • Transfer mode
    • Buffering method
  • Comprehensive multithread support for maximum performance
  • Supports TWAIN 1.x and 2.x drivers
  • Get and set all TWAIN capabilities that the TWAIN driver supports
  • Create custom user interfaces to expose only specific functionality or use the default user interface provided by the TWAIN driver
  • Bypass the user interface for completely automated tasks and batch scanning
  • Utilize events and callbacks for per-page processing
  • Show the TWAIN source manager's selection dialog to select a TWAIN driver, create a custom selection dialog, or select a TWAIN driver programmatically
  • Scan in black and white, halftone, grayscale, palette, and full color
  • Control the resolution, position, size, and orientation of the acquired image
  • Use an automated document feeder (ADF) for single and multi-page scanning
  • Simultaneously scan the front and back of a page with duplex scanners
  • 32 and 64-bit TWAIN binaries
  • Available as .NET (C# & VB) classes, C DLL, and C++ classes

LEADTOOLS Fast TWAIN is Better

There are three main types of hardware drivers to scan images: TWAIN, WIA, and ISIS. Historically, ISIS had been known to be the driver of choice when speed was a main factor because only ISIS drivers could take full advantage of the hardware's capabilities. The major drawback to ISIS drivers is licensing. Either the hardware manufacturer has to increase the price of the hardware to pay for the ISIS driver, or the hardware ships without a driver and the end-user has to deal with the hassle of purchasing the ISIS driver.

In contrast, TWAIN drivers are generally free, but historically could not be used in applications where speed was important because of TWAIN's generic nature. However, changes to the TWAIN specification have addressed the utilization of the built-in capabilities of hardware to make scanning faster. These changes to TWAIN, combined with using LEADTOOLS Fast TWAIN technology, have made TWAIN as fast as, and in most cases, faster than ISIS.
