What is Dynamic TWAIN

Dynamic TWAIN is a COM/ActiveX control which enables you to acquire images from any TWAIN compatible devices. With the carefully designed interface, and the built-in wizard mode, Dynamic TWAIN is very easy to use. You can typically do your TWAIN job in several lines of code. At the same time, Dynamic TWAIN is very powerful. It is compatible with TWAIN specification V1.9. It has built-in JPEG encoder and decoder. It supports all three image transfer modes and many other features.

Dynamic Web TWAIN is also available. It has many features specifically designed for web environment, such as uploading and downloading images through FTP or HTTP protocol. Image can be displayed within Dynamic Web TWAIN without exchanging image data between the ActiveX control and the <img> HTML tag.
