LEADTOOLS Fast TWAIN SDK

Fast TWAIN

LEADTOOLS Fast TWAIN intelligently analyzes the TWAIN source, considering the requested bits per pixel, image type and compression, and finds the best compression type, transfer mode and buffering schemes to get the best performance possible.

LEAD has researched and developed 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’ multi-threaded infrastructure to process and compress data while scanning, LEAD is able to dramatically increase the speed of scanning even when using standard TWAIN sources.

Overview of LEADTOOLS Fast TWAIN SDK Technology

  • Supports TWAIN 1.x and 2.x drivers
  • 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 to code special 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 or full color
  • Control the resolution, position, size, and orientation of the acquired image
  • Use an automated document feeder for single and multi-page scanning
  • Scan both front and back of page with duplex scanning
  • Native 32 and 64 bit TWAIN binaries
  • Available as C DLL, C++ classes, .NET classes and WF activities
  • For single and multi threaded Windows and web based applications

LEADTOOLS Fast TWAIN is Better

Basically, there are three main types of hardware drivers to scan images: TWAIN, WIA and ISIS. Until recently, ISIS had been known to be the driver of choice when speed has been a main factor because only ISIS drivers could take full advantage of the hardware's capabilities. The major drawback to using 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 had 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 some cases faster than ISIS.
