I need to add TWAIN scanning to an Delphi application and am having trouble locating an off-the-shelf component to do so. I downloaded TDelphiTwain but, when used in D2010 on Windows Vista, it does not appear to recognize any Twain sources on my system. I also tried the trial version of Twain Toolkit for Delphi from MCM which has the a...
I am using EZTWAIN from a powerbuilder application to acquire images from an HP scanner. Recently I tried a Kodak model (i1120) and it seems that it is not supported. Specifically the application freezes during the scanning process (perhaps the problem has to do with duplex scanning). Can you recommend another library that you have use...
Hi, is there a way to set my default values for paper source and papir size when showing Twain CommonUI dialog. Paper source is always 'flatbed' and paper size 'Letter...' Thanks ...
Has anyone tried TwainDotNet for scanning with TWAIN API calls from .NET? Though it works well usually I've some issues with it when used along with WPF application using MVVM. Basically I'm calling Twain scanning functions from a Service, which in turn uses a BackgroundWorker. List<BitmapSource> bitmapSources = new List<BitmapSource>()...
We are developing C#.NET web application, which MUST have possibility to connect to front-end user's scanner, webcam or sign-pad (http://www.signotec.com/) device and execute their actions. This should be embedded with browser. AS far as I know it's possible with Java, AIR, Silverlight4 (it's still beta). What do you prefer it's best ...
I have been tasked with integrating image acquisition into a .NET application and I have been looking for an API to use for performing this function. I have come across several "standard" APIs, some have been in existence for a long time, some not so long. I have looked at references to ISIS, TWAIN, WIA, and SANE (said to be mostly *ni...
I am coding a scanning application and I need to have end of page detection so I don't scan past where the document ends, does anyone what settings to use to turn this feature on for TWAIN drivers? code samples in vb.net or C# would be great :) ...
I'm trying to determine what version of the TWAIN specification I can write my software to utilize and want to find out which version of the specification the twain.dll that comes with Win7 x64 implements. The file info is as follows: File Version: 1.7.0.0 Product Name: Twain Source Manager Product Version: 1,7,0,0 Size: 92.5KB Date Mo...
I need to add a web-based capability to allow users to scan images using a local TWAIN or WIA compliant scanner or digital camera and then upload those images to the server. (The scanning experience should be integrated into the web UI as opposed to just allowing them to scan it locally using whatever tools and then upload the resulting...
I developed a custom made (.EXE) application to scan document using TWAIN and would like this software to be part of the list of scanners that appear in the Events tab within the Scanners properties window. does anyone have an idea how this can be achieved? ...
Okay, here's my setup. I have a c# app working perfectly on all 32-bit Windows XP-Vista-7 machine. I already have a verisign PFX to support the ClickOnce deployment and is using Atalasoft DotTwain 8.0 as the 3rd party scanner helper. When I publish my application, I choose "Any CPU" as the Platform target. When I try to make it run on ...
Hi all, I need to perform a scanning of areas which do not meet standard sizes of A3, A4 etc. Those scans have to be loaded and post processed by custom application. The rough idea of my colleague was to disassemble standard scanner and attach optics + electronic (somehow) to a custom device which will navigate it (continuously) through...
I've written an applet to allow scanning. This applet uses the TWAIN standard. This standard is used to communicate with scanners. I know TWAIN requires access to UI threads in Windows. The code I wrote worked well when it was used in an applet. The problem starts when I try to use the same code in an console application. I suspect this ...
I'm currently working on a project where we want to interface with TWAIN scanners on both the PC (Windows) and the Macintosh. On Windows, we basically have everything squared away and the code works successfully with the vast majority of scanners. On Mac OS X, we also basically have everything working and with the main scanner we used...
I'm using a slightly modified version of Twain Dot Net in my scanning application. The problem is, when the user cancels scanning using a button on the scanner (or if paper jams), TWAIN should show an error message and return with some failure code. But instead, what happens is that the call to DG_IMAGE / DAT_IMAGENATIVEXFER / MSG_GET r...
