Fast TWAIN SDK Libraries

LEADTOOLS Fast TWAIN libraries utilize artificial intelligence to analyze a TWAIN source's capabilities to find the perfect combination of compression, transfer mode, and buffering scheme that provides the best possible performance for the requested image type.

Feature-rich Fast TWAIN SDK

Fast TWAIN Libraries

LEAD continues to research and develop special techniques to get the most from any TWAIN 32- or 64-bit source. LEADTOOLS Fast TWAIN API dramatically increases the speed of scanning, even when using standard TWAIN version 1.x or 2.x sources, by analyzing available hardware capabilities to apply compression technology, implement advanced buffering techniques, and utilize LEADTOOLS' optimized multithreaded infrastructure.

Faster TWAIN is Faster than ISIS

Fast TWAIN Versus ISIS

Before LEADTOOLS Fast TWAIN, ISIS had been known as the driver of choice when speed was the 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 is left to deal with the hassle of purchasing the ISIS driver.

In contrast, TWAIN drivers are generally free, but 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 many cases, faster than ISIS.
