  • HTML5 Web Scanning with LEADTOOLS

    TWAIN scanning and document capture is an essential aspect and starting point of most document imaging applications. For web developers, this is a problematic requirement due to the localized, hardware-dependent nature of TWAIN scanners and image capture devices. Many roadblocks await the developer and most often the client is left with tedious and time-wasting inconveniences that make the application difficult to use. LEADTOOLS has developed a Web Scanning SDK that solves many of these obstacles and offers a programmer-friendly and customizable framework for integrating TWAIN scanning into any web-based document imaging solution.

HTML5 Web Scanning SDK

The LEADTOOLS HTML5 Web Scanning toolkit is an advanced cross-browser application framework which can control any scanner, digital camera, or TWAIN-enabled device from a web application using any HTML5 compliant browser including Internet Explorer, Chrome, Firefox, and more. It uses a self-hosted web service executable to communicate with the scanner and apply image processing. It also includes a server-side File Upload service which can be customized for advanced processing and workflow steps including File format conversion, SharePoint archival, OCR, Barcode and Forms Recognition.

NOTE: Since the release of this video, the Web Scanning Demo and setup utility have been updated. Some portions of the video may not reflect the current released product. There is no longer a separate utility for the Web Services, and the Web Scanning demo has been merged into a single ASP.NET Web API Project.
