Dynamic Web TWAIN is a TWAIN scanning SDK specifically optimized for web applications. The TWAIN ActiveX/Plugin allows you to access a connected scanner in jаvascript & HTML. With a couple of lines, you can scan a batch of documents from TWAIN compatible scanners or acquire images from digital cameras/capture cards. Depending on the library, users can edit the scanned images (rotate, crop, etc.) and save them to a variety of file formats, database, Sharepoint, or other ECMs. The TWAIN control also supports loading and processing local images.
