VintaSoft Twain .NET SDK enables users to acquire images from scanners or cameras with or without device UI. With capabilities to get device information and a list of TWAIN-connected devices, the professional scanning library makes acquiring images an easy process.

With VintaSoft Twain .NET SDK, users can easily generate a list of all TWAIN devices installed on their system, as well as access information about the capabilities of each device. This SDK also enables users to acquire images from their device with or without the device UI, utilizing either the flatbed or document feeder. Duplex mode is also supported, meaning users can capture images on both sides of the page.
But the capabilities of VintaSoft Twain .NET SDK don't stop there. This software also allows for the use of imprinter capabilities on the device, as well as image processing and clean-up. And once you have your images, you can save them directly to your local disk or into a table of an SQL database. Alternatively, you can upload your images to an HTTP(S) or FTP server.
In terms of image format compatibility, VintaSoft Twain .NET SDK has you covered. The software provides built-in codecs for BMP, GIF, JPEG, PNG, TIFF, multipage TIFF, PDF, and PDF / A formats.
Developers will appreciate that this SDK includes pure .NET Framework 3.5 / 4.0 and .NET Core 3 assemblies which can be used in any application environment, including WinForms, WPF, console, and ASP.NET. Additionally, VintaSoft Twain .NET SDK has been rigorously tested and comes with examples of use in MS Visual Studio .NET 2008 / 2010 / 2012 / 2013 / 2015 / 2017 / 2019 for VB.NET, C#, and ASP.NET.
Overall, if you need a reliable, flexible tool for acquiring images from your devices, VintaSoft Twain .NET SDK is an excellent choice.
Version 11.0: Added support for .NET Core 3 and ASP.NET Core 3 for Windows. Improved compatibility with Kodak and Fujitsu scanners. Created the platform-independent .NET Core web service for working with TWAIN devices and new demos for .NET Core and ASP.NET Core MVC.
Version 10.3: Created the unified access to 32- and 64-bit TWAIN drivers from 64-bit apps. Previously, the 32-bit drivers couldn't be used in 64-bit applications and that was inconvenient since the majority of scanners are still delivered with 32-bit drivers only.
Version 10.2.2.3: Now Web TWAIN service solution can be used on HTTPS server. Platform-independent web TWAIN service created. New Web API 2 controller for ASP.NET MVC 5 created. Compatibility with jQuery v2-v3 verified. Demos for VS .NET 2017 added.
Version 10.2.1.1: Now Web TWAIN service solution can be used on HTTPS server. Platform-independent web TWAIN service created. New Web API 2 controller for ASP.NET MVC 5 created. Compatibility with jQuery v2-v3 verified. Demos for VS .NET 2017 added.
Version 10.2.0.1: Now Web TWAIN service solution can be used on HTTPS server. Platform-independent web TWAIN service created. New Web API 2 controller for ASP.NET MVC 5 created. Compatibility with jQuery v2-v3 verified. Demos for VS .NET 2017 added.
Version 10.1: Created new easy ways to add the Twain SDK into web apps with multi browser support. The SDK can be used in any modern web browser. Created ASP.NET MVC and WebForms demos with local services based on WCF service, API controller and JavaScript code.
Version 10.0: The new version significantly improves the image acquisition algorithm making it fully asynchronous, the algorithm that cancels image scanning and the WPF version of the SDK, adding also a lot of major and minor fixes.
Version 9.1: Added the ability to get info about asynchronous events of device. Some improvements in synchronous image acquisition for better compatibility with Kodak scanners and in WPF assembly for much better compatibility with Plustek and Sceye scanners.
Version 9.0: Added TWAIN v2.3 standard support. Improved work with list of devices and process of image acquisition cancellation. Added abilities to stop and resume receiving pages from ADF and to manage batch buffer of scanner. Important changes made in the SDK architecture.
Version 7.1: Control a scanner or camera from your .NET application. What's new in the version: .NET Framework 4.0 Client Profile supported. Memory usage and image processing functions optimized. Image acquisition algorithm optimized for better compatibility with HP and Canon scanners; and WIA scanner drivers.
