Atalasoft DotTwain is a 100% Managed .NET Windows Form component allowing fast capturing of digital images from scanners, cameras, and other devices supporting TWAIN. It utilizes the improvements of the TWAIN 1.9 specifications for ultra fast scanning. It works with a .NET Bitmap object and has no dependencies other than the .NET Framework. This is intended for a small footprint "no-touch" deployment over the web or if you need scanning abilities without Atalasoft DotImage or as an integrated scanning solution with DotImage.

DotTwain Scanning and AcquisitionPowerful Lightweight Scanning Control - Finally, a powerful lightweight scanning component for .NET is available! DotTwain can be used for acquiring images directly to an in-memory image, a file, or posted to the web. Only one 172 kb assembly is required for deployment.
To add simple scanning to your applications, simply drop this component onto your form, and write one line of code.
[C#]
Bitmap bmp = this.acquisition.AcquireModal(false);
[Visual Basic]
Dim bmp As Bitmap = Me.acquisition.AcquireModal(False)
To add more advanced capabilities, including scanning from an automatic document feeder or acquiring multiple images from a camera, just handle the ImageAcquired event which is fired for each image that's acquired. The Device object includes over 70 properties that can be set to directly control the TWAIN driver when scanning images.
No COM Dependencies - Due to the lack of many vendors fully supporting .NET in their advanced components, developers have begun to accept COM as part their.NET applications with no other alternatives. This is against Microsoft's.NET philosophy which eliminates "DLL Hell", allows for easy and secure deployment, and uses a modern Object Oriented programming model. DotTwain fully adopts Microsoft's .NET philosophy without any COM dependencies, "X-Copy" deployment, and a modern object oriented design.
Web Deployment - DotTwain can be deployed over the web by being embedded into Internet Explorer, or part of a web-deployed Windows Form application. See our web-deploy demo for an online example.
