barcode

How do we do programmatic reading of a barcode that is captured using a mobile phone camera? For example, how do that using iPhone or Android or Java ME? Do we need separate hardware to read bar code or can we do image manipulation? Google has made this INCREDIBLY simple with their Zebra Crossing libraries. They have support for doing scanning via images on the following platforms: J2SE Android and others have ported to: J2ME CSharp CPP Rim iPhone Bug As another poster already mentioned, on Android you could also use an Intent to call Barcode Reader with something like: public Button

I have been researching all morning about integrating an android barcode scanner app into a web page, but haven't found exactly what I need to know. I want to have a web page that the user can fill in text fields by using an android barcode scanner. So the user would be on a web page and would either click inside the text field or click a button next to the text field that would start the android barcode scanner. They would then scan the barcode and the text field would be filled in. I have found solutions on how to do this and then go to a different page, but it is important that the user

I'm building the world's simplest library application. All I want to be able to do is scan in a book's UPC (barcode) using a typical scanner (which just types the numbers of the barcode into a field) and then use it to look up data about the book... at a minimum, title, author, year published, and either the Dewey Decimal or Library of Congress catalog number. The goal is to print out a tiny sticker ("spine label") with the card catalog number that I can stick on the spine of the book, and then I can sort the books by card catalog number on the shelves in our company library. That way books on

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 coming from the barcode scanner, not from something the user typed on the keyboard. Did you check the

I am working on an android app that uses Google Barcode Scanner API from Mobile Vision. The purpose of app is to detect barcode and then take some action based on the data associated with barcode. As soon as first barcode is detected, I want to stop the camera source so that the detection shouldn't continue. When I try to execute cameraSource.stop() inside receiveDetections(Detector.Detections<Barcode> detections) callback, the thread gets blocked and there is a lot of log output in logcat. Since this callback is not executed in UI thread, UI remains unblocked. I tried executing cameraSource

Going through the steps mentioned here and using IDAutomationCode39, I am getting the barcode image, however they are very blurr and only scans bigger size images. My barcode id will be upto 30 characters long, which is causing a very wide barcode image. Where could the problem lie? Is it the IDAutomationCode39 or my setting in my button click event below? private void button1_Click(object sender, EventArgs e) { string abbre = GenerateProdCodeFromProductName(); txt2.Text = abbre; string barcode = txt1.Text; Bitmap bitm = new Bitmap(barcode.Length * 45, 160); bitm.SetResolution(240, 240); using

Does anyone know how to remove text below a bar-code? Bar-code is generated using barcode.py library. I was trying to check in https://bitbucket.org/whitie/python-barcode but could not find solution,what properties should be written in barcode saving line in python: ean = barcode.get('code39', str(row['PART']), writer=ImageWriter()) Attaching barcode picture with marked line what i would like to remove from barcode generation. try this: barcode.default_writer_options['write_text'] = False Looking at the code, it appears you can set the attribute 'human' (human-readable text) to a non-empty
