DotTwain Scanning and Acquisition

強大的輕量級掃描控件

• DotTwain是一個強大的輕量級.Net框架掃描控件，能夠獲取圖片到內(nèi)存，文件，或者提交到web服務(wù)器上，整個大小只有172kb.
  
  添加簡單的掃描功能到您的應(yīng)用程序中，只需要拖動該控件到您的應(yīng)用程序表單中，并且加上下面的一行代碼就可以了
  
  [C#]
  Bitmap bmp = this.acquisition.AcquireModal(false);
  
  [Visual Basic]
  Dim bmp As Bitmap = Me.acquisition.AcquireModal(False)
  
  當(dāng)然，也可以通過控制在獲取圖片是所觸發(fā)的ImageAcquired事件來完成復(fù)雜的操作，該對象包含了超過70個屬性，可以對TWAIN driver掃描圖像做到完美控制.

完全不依賴COM

• DotTwain是一個完全的.Net控件，并使用目前流行的面向?qū)ο笤O(shè)計模式，基于純粹的.Net框架，沒有任何對COM的依賴.

開發(fā)web應(yīng)用

• DotTwain 能夠被有效的嵌入到Internet Explorer中，或者作為基于web部署的Windows Form應(yīng)用程序的一部分，具體的應(yīng)用可以參考商家官方網(wǎng)站的在線示例

• 圖片dataset支持，允許從照相機上獲得指定的圖片
• 快速確認(rèn)兼容性，壓縮方式，圖片大小等.
• 超過70種屬性設(shè)置，可以完美控制整個操作

DotTwain Scanning and Acquisition

Powerful Lightweight Scanning Control

• Finally, a powerful lightweight scanning component for .NET is available! DotTwain 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. See our web-deploy demo for an online example.

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.
