LEADTOOLS Fast TWAIN
LEADTOOLS FAST TWAIN intelligently
analyzes the TWAIN source, considering the bits per pixel,
image type and compression requested from the TWAIN device,
and finds the fastest compression type, transfer mode and
buffer schemes to get the best performance possible.
LEAD has researched and
developed special techniques to get the most from normal
TWAIN sources. By taking advantage of available hardware
capabilities such as hardware compression when available,
the application of LEADTOOLS hand optimized compression
technology, newly developed buffering techniques and multithreaded
infrastructure to process and compress data while scanning,
LEAD is able to dramatically increase the speed of scanning
even when using standard TWAIN sources.
Fast TWAIN Is Better
Basically, there are two main types of hardware
drivers to scan images: TWAIN 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 has been licensing. Either
the hardware manufacturer had to increase the price of the
hardware to pay for the ISIS driver, or the hardware shipped
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 could not be used in applications where speed was important
because of TWAIN's generic nature. However, recent changes
to the TWAIN specification are addressing the utilization
of the built in capabilities of hardware to help make scanning
faster. These changes to TWAIN in combination with using
LEADTOOLS Fast TWAIN technology, TWAIN is now as
fast or faster than ISIS. What could be better than fast
and free?
