C# TWAIN - Control Acquisition with Device Object

C# TWAIN: Get Device Object Through Acquisition Overview

This C#.NET TWAIN SDK is designed to assist in image acquisition and TWAIN image scanning process control in C#.NET application. The Acquisition object is the main class in RETwain and it enables developers to realize basic image acquisition, image saving to file or image conversion to TWAIN device supported image formats. If you want to achieve better control over the acquisition process, you may need the Device object that generates from methods from Acquisition object APIs. You can get Device object through methods from Acquisition object class. c# pdf free, mvc print pdf, itextsharp insert image into pdf vb.net, vb.net print to pdf, create thumbnail from pdf c#, c# combine tiff files into one. Using Device object, it is able to open and close connection to TWAIN device, check all properties of the TWAIN device, customize scanning size and location, finish scanning from Console based application or scan multiple pages into a single PDF file.

We have provided DLLs and licenses you need for applying this C#.NET TWAIN SDK into your application to control TWAIN image acquisition with the Device object on this guide page. You can also find detailed APIs and C# demo code for obtaining the Device object from Acquisition object in order to customize the TWAIN image scanning process for specific purpose on this page. If you want to know more information on TWAIN device control in C#.NET application, you may read the last part of this page carefully. c# extract pdf page as image, vb.net get pdf page count, c# wpf preview pdf, c# itextsharp convert text file to pdf, how to read specific text from pdf file in c#, vb.net pdf to word, c# generate pdf from html template.

Completely compliant with .NET Framework 2.0 or later versions, this C#.NET TWAIN SDK can be used to obtain Device object from methods in the Acquisition object class. best pdf preview in asp net c#, asp.net pdf editor control, free asp.net tiff viewer, best pdf viewer control for asp.net, asp net replace text from pdf javascript, open word file in asp.net c#, mvc display pdf from byte array. To use it in your C#.NET project created in Visual Studio 2005 or later versions, you may have to make some preparations. For example, you need to install TWAIN in your system in the first place. And there should be leastwise one device that fully supports TWAIN.

C# TWAIN: APIs for Controlling Process with Device Object

Detailed C# APIs are provided here to guide you control C#.NET TWAIN image acquisition process with the Device object. After obtaining the Device object, it is possible to realize featured scanning process easily.

Device Acquisition.GetDevice(String deviceName);
Acquisition.Devices;
Device Acquisition.ShowSelectSource();
Acquisition.GetAvailableSource;

C# TWAIN: Demo for Getting Device Object Through Acquisition

C#.NET demo code below can be used to obtain the Device object from Acquisition object class with high accuracy.

// Get Device Object Through Acquisition
public Device GetDevice()
{
   Acquisition acq = new Acquisition();
   return acq.ShowSelectSource();
}
