What is Dynamic Web TWAIN
Dynamic Web 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 Web TWAIN is
very easy to use. You can typically do your TWAIN job in several lines of code.
At the same time, Dynamic Web TWAIN is very powerful. It is compatible with
TWAIN specification V1.9. It has built-in JPEG codec. It supports all three
image transfer modes and many other features.
Dynamic Web TWAIN has many features specifically designed for
web environment, such as upload and download images through FTP or HTTP
protocol. Image can be displayed within Dynamic Web TWAIN directly, without
exchanging image data between the ActiveX control and the <img> HTML tag, and
the initial image can be downloaded from web server.
Features:
Developed directly with pure Win32 API and assembly language, which make
Dynamic Web TWAIN,
Small: no C/C++ run time library is used. Even with built-in JPEG
codec, the size of the DLL file is 120K, and the size of the CAB file is
only 55K;
Fast: the core engine of JPEG codec and the image processing part
of the Dynamic Web TWAIN is optimized with assembly language;
Easy to distribute: absolutely no supporting DLL is needed for
distributing.
TWAIN specification 1.9 compatible.
Strong internet support: download and upload image through HTTP or FTP,
built-in JPEG encoder and decoder make the transfer faster.
Marked safe for initializing and scripting.
Can be deployed in .NET environment as an unmanaged control.
Can be used in any COM-enlightened program language, such as Visual C++,
Visual Basic, Delphi, HTML/VBScript/JavaScript, PowerBuilder and so on.
Supports Native, Buffered Memory and Disk File image transfer modes.
Both single page and multi-page TIFF are supported.
Built-in wizard mode manages the states of the TWAIN session intelligently
and makes the Dynamic Web TWAIN easy to use.
Built-in JPEG encoder enables you to compress the acquired image no matter
whether the TWAIN source has the capability.
Sample code provided: C#, VB.NET, VC, VB, Delphi, HTML (VBScript,
JavaScript).
Supports auto document feeder (ADF) and multiple images acquisition.
Can set and read common device features through properties, such as:
IfAutoFeed, IfAutoScan, Resolution, BitDepth, Brightness, Contrast, Unit,
Duplex and so on.
