TWAIN and 64 bit OS

Why has Microsoft abandoned TWAIN?  WIA just doesn't have the features that graphics artists are used to using with TWAIN drivers.  For example, my Epson scanner TWAIN driver supports: Resolution, Target Size, scaling, trimming, Unsharp mask, Descreening, Back light correction, Dust Removal with ICE support.  Adjustments like Auto exposure, tone correction, image adjustments and color correction.

 

WIA?  Has very limited adjustments like resolution and brightness/contrast.

 

If Microsoft wants to keep the graphic industry to use WINDOWS instead of a Mac, we need better scanning support under 64bit OS!

Well, it's not entirely Microsoft's fault.

The Cause of the Problem

Most scanner vendors are too lazy to supply 64bit TWAIN drivers. They only offer 32bit TWAIN drivers, thus 64bit applications can not access scanners through 64bit TWAIN.

The Solution: Access Scanners from 64bit Applications

Asprise Scanning C# VB.NET Twain Scanner SDK is probably the only scanning library that works for both 64bit and 32bit applications thanks to the innovative technology that bridge 64bit applications to 32bit TWAIN seamlessly. 

Supports Both 64bit & 32bit Apps

Asprise Scanning SDK is probably the only scanning library that works for both 64bit and 32bit applications thanks to our innovative patent pending technology and quality implementation.
