Born2Wire Posted October 8, 2006 Report Posted October 8, 2006 Hi, I was wondering if anyone had used LabVIEW and/or the NI Vision tools to get pictures from a flatbed scanner? If so, what tools did you use, and what did you think of them? Thanks! Quote

Thanks! I have used Alliance Vision's TWAIN package. I does a good job. I have currently had a problem using this software with a Nikon LS-5000 scanner so I tried Vintasoft's TWAIN.Net package and it works pretty well too. They also offer an ActiveX version. Quote
crelf Posted October 9, 2006 Report Posted October 9, 2006 I have used Alliance Vision's TWAIN package. I does a good job. I concurr - and you can get a demo version from the too Quote

gap Posted October 9, 2006 Report Posted October 9, 2006 This looks like a good tool. I was wondering if (without opening and viewing the Zip file,...) Does this demo let you use a twain device as a webcam (slow motion) with Labview? Cheers! Quote

Born2Wire Posted October 13, 2006 Author Report Posted October 13, 2006 I finally tried the Alliance Vision Twain driver for LabVIEW. It worked out of the box. If the rest of it as slick as the demo, then it is truly a nice piece of work. A bit steep for personal projects, but that's life I suppose. Quote
whalua Posted January 24, 2007 Report Posted January 24, 2007 Hi First of all I'm sorry for my english language, I don't speak it very well I'd like to thank you for your information about the twain driver for labview. In fact, I've a problem with a camera connected to PC and I hope I will solve my problems with this software My goal is to acquire images in labview, but now I can handle the camera only with a software called Flashpoint. If in the future I'll have some problems in my work, is there anyone who will help me ? Thank you very much Have a goog day Claudio from Italy Quote
whalua Posted January 25, 2007 Report Posted January 25, 2007 Hi I tried to use the demo version of Alliance driver. Using TWAIN DEmo_ex.vi I always get a message "Setting capability state < 4" for every value of resolution I pass to the driver. Even deleting this function from the block diagram, I get a message in the next function ? Is there anybody can help me ?? Thank you Have a great day Quote
whalua Posted February 1, 2007 Report Posted February 1, 2007 Hello I've been able to use Alliance twain demo driver ! ! ! But when I run the VI, a message like "Demo version. Contact Alliance for registration" always appears during running. The problem is that I don't have money to buy the license Do any of you knows a trick under labview to bypass this message ? Thank you for your attention Have a good day Claudio Quote
crelf Posted February 1, 2007 Report Posted February 1, 2007 Do any of you knows a trick under labview to bypass this message? Here's a trick that's garunteed to work or your money back: buy it. Quote
Rolf Kalbermatter Posted February 5, 2007 Report Posted February 5, 2007 HelloI've been able to use Alliance twain demo driver ! ! ! But when I run the VI, a message like "Demo version. Contact Alliance for registration" always appears during running. The problem is that I don't have money to buy the license Do any of you knows a trick under labview to bypass this message ? Thank you for your attention Well being myself in the business of developing drivers for a living among other LabVIEW work I can't really feel sympathy for your problem. Maybe that is because of the first A in LAVA? Rolf Kalbermatter Quote
