Atalasoft DotTwain

What’s New in DotTwain 8.0c

Bug Fixes:

• Fixed a bug in the Twain Control demo that would cause a "No devices found" message
• Fixed a bug in the VB Twain Control demo
• Fixed the Twain Control's configuration file to point to the correct URL
• Fixed an issue where .NET would cause an exception for Grayscale scans

Atalasoft DotTwain 8.0b New Features

• Added support for PixelFormat selection support to the DotTwain ActiveX Control
• ActiveX DotTwain now supports public key licensing
• Added links inside of the Toolkit Activation to help in choosing an evaluation
• Added a feature to ActiveX Twain to allow saving to a file locally instead of immediately uploading

What's New?

• DotTwain supports 32- and 64-bit TWAIN 1.x/2.0 drivers
• An AutoDiscardBlankPages property was added. For drivers that support this feature it will automatically skip scanned pages it believes to be blank
• Added LoadXmlParameters and SaveXmlParameters methods. Theses methods can be used to save and restore device settings without the driver needing to support any special capability

Scanning and Aquisition
DotTwain is a lightweight .NET scanning component that can be used for acquiring images directly to an in-memory image, a file, or posted to the web. Only one 172 kb assembly is required for deployment.

To add simple scanning to your applications, simply drop this component onto your form, and write one line of code.

[C#]
Bitmap bmp = this.acquisition.AcquireModal(false);

[Visual Basic]
Dim bmp As Bitmap = Me.acquisition.AcquireModal(False)

To add more advanced capabilities, including scanning from an automatic document feeder or acquiring multiple images from a camera, just handle the ImageAcquired event which is fired for each image that's acquired. The Device object includes over 70 properties that can be set to directly control the TWAIN driver when scanning images.

No COM Dependencies
Due to the lack of many vendors fully supporting .NET in their advanced components, developers have begun to accept COM as part their.NET applications with no other alternatives. This is against Microsoft's.NET philosophy which eliminates "DLL Hell", allows for easy and secure deployment, and uses a modern Object Oriented programming model. DotTwain fully adopts Microsoft's .NET philosophy without any COM dependencies, "X-Copy" deployment, and a modern object oriented design.

Web Deployment
DotTwain can be deployed over the web by being embedded into Internet Explorer, or part of a web-deployed Windows Form application.

Features:

• Full context sensitive help and documentation
• Object-oriented design; a TWAIN extension to the .NET Framework
• Create a custom interface to scan images, or use the default TWAIN interface
• Automatic Document Feeder support, with full control of the feeder operations
• File system support for navigating the internal device memory
• Acquire images directly to file utilizing compression algorithms supported by the device
• A select region of the scanning bed to be acquired with frame support
• Upload a scanned image to a server with the built in HTTP Post class
• Supports Web Deployment ; Embed into an Internet Explorer Browser or deploy as a WinForms application
• Simplified automatic capture allowing the device to quickly capture multiple images for later acquisition
• Imprinter/Endorser methods allowing a text string ito be stamped onto the acquired image during the acquisition
• Image dataset support enables acquisition of specific images from a camera in a single operation
• Quickly find out what capabilities, compression modes, frame sizes, resolutions and more, are supported by a device
• Over 70 properties to give total control over the image acquisition
