问题 I have barcode images in jpg format and want to extract barcode # from those. Please help! 回答1: See the CodeProject article: Reading Barcodes from an Image - II. The author (James) improves (and credits) a previously written VB library to decode barcodes from an image using only .NET code. There are two projects in the downloadable solution: The barcode library - written in C# The test app - written in VB I have successfully used the C# code in VS2008 against a JPG image with an extended

问题 I recently acquired a Metrologic Barcode scanner (USB port), as everyone already knows it works as a keyboard emulator out of the box. How do I configure the scanner and my application so that my app can process the barcode data directly? That is, I don't want the user to focus on a "Text field" and then process the data when the KeyPress event fires. 回答1: Usually barcode scanners can be configured to send some characters before and after the string. So if you append eg "F12" before the

问题 I have been developing an android app to scan the barcode and QR code and send the results to some other application (HTTP). I have read most of the documentation over internet and here in stack over flow and got it working. I could able to run the stand alone zxing android app on my device, also I could run my own separate android app to use Zxing intent to scan the bar code. But even after reading so many questions here and some of the blogs in internet, I could not get my strict

问题 Can someone tell me if creating barcode scanner app (for Android) is difficult? Is OpenCV library good start? Where can I find algorithm which clearly explains how to read barcodes? I will appreciate all good materials about this topic! Thanks in advance! 回答1: The ZXing project provides a standalone barcode reader application which — via Android's intent mechanism — can be called by other applications who wish to integrate barcode scanning. The easiest way to do this is to call the ZXing SCAN

I'm seeking a library, technique or advice on how to read an EAN-13 barcode from an image (including ISBN,and ISSN encodings). The image would come from a mobile phone or webcam, so resolution may be quite poor and not well aligned. I'm specifically interested in something that could be used from ruby on rails,

问题 hey all. I have a barcode scanner connected to a PC that working with a c# program.now i want to distinguish between the scanner and the keyboard which one is sending data to my program. can everyone help me with a code or advise in c#? somebody said this to me in another topic(but i can't do this yet): basically you can configure the scanner to send some characters that basically tell the computer "hi, it's me". When you see those characters in your input stream, you know the information is

问题 I want to implement standalone scanner in my android application.I'm using zxing's core.jar library in my project. I need to decode a barcode from camera preview.But i don't know how to implement it.Because there is no official documentation. Can you provide me a simple example on followings things? 1.Initialize the camera and getting preview. 2.Decode the barcode from preview. or Is there any example project to do this? 回答1: Take a look at my simple implementation: https://github.com/piobab
