TWAIN SDK Libraries
LEADTOOLS provides everything needed to control any TWAIN scanner, digital camera, or capture card and is an important component of many business workflows. With LEADTOOLS, .NET (C#, VB), C, C++, and web developers can use TWAIN to capture images for OCR, barcode, forms recognition, image processing, annotation, and more. High-level acquisition functions are included for ease of use while low-level functionality is provided for flexibility and control in even the most demanding scanning applications.
Flexible TWAIN Driver Interface
The LEADTOOLS TWAIN libraries can get and set all TWAIN capabilities supported by 32- and 64-bit TWAIN versions 1.x and 2.x device drivers. This facilitates the bypass of the driver's built-in user interface so you can build a custom interface that saves settings across sessions and is consistent when using different TWAIN devices to make your solution extremely user friendly. The libraries can even completely bypass a user interface all together to create completely automated solutions to scan bitonal, halftone, grayscale, palettized, and full color simplex and duplex images from the flatbed or ADF.
Build Screaming Fast TWAIN Solutions
The LEADTOOLS TWAIN libraries completely support running in multithreaded applications. When paired with per page callbacks, your solution can process a page while the next pages are being acquired. For even better performance, the LEADTOOLS Fast TWAIN component uses artificial intelligence to interrogate the TWAIN driver and set the scan settings for the absolutely fastest scanning speed the device can handle.
Web and Cloud Scanning
The source code of a complete web scanning framework is included in the LEADTOOLS installation. This programmer-friendly and modular web scanning architecture is perfect for creating new innovative web applications or to add web scanning to existing web applications, frameworks, and workflows such as SharePoint and CRM.
Easy to Integrate
LEADTOOLS handles the heavy lifting — eliminating months of R&D, while giving you the best quality and performance available. This leaves you free to focus on other components of your application.
