Reading barcodes

Hi all,
I have generated a barcode using barcode4j API. I want to read the encoded data from the generated barcode using Java. Plz explain the entire process how to read the data from the barcode using Java. Any help is highly appreciated.
Thanx,
Har Krishan

You don't read from a scanner in any case. You read from whatever device the scanner is plugged into.
For example if the scanner plugs in where your keyboard plugs in, then you read from the keyboard. If it plugs into a serial port then you read from the serial port. And so on.

Read barcode scan without textbox focus

I have 16+ scanners coming into the computer from a single USB port. The code that I have now works fine as long as the textbox has focus. What I want is some code that I could use that would get the scan even if the windows form is minimized
or some other program is being used.
I've looked around a lot and everything just says to have focus on the textbox. Is there like a barcode listener that I could use?

Hi saprest,
When you have focus in a testbox, it sends characters to the textbox as if you typed them from the keyboard. If you don’t want to use a testbox, you would subscribe to a keyboard event handler to capture the barcode stream.

If you need further assistance with this issue, you'll need to repost in a generic Java forum, or perhaps do a google search for a barcode-reading library.

ADF Mobile: Reading barcodes from camera

Hi everyone,
We are planning to develop an ADF Mobile application. One of our client requirements is that they can use Mobile camera to read barcodes from their products. We have tried to use Zxing for barcode recognizion but we get a poor level of successful recognizion
Is there any way to read barcodes from photos (any kind of plugin or recommended library) that we can use in combination with ADF Mobile to get this feature? Has anyone worked with any other library that can recommend us to use for achieve a better successful level?
Thanks in advance for your help,

Hi, thanks for your comments, but what would be the possible solution for developers who want to read barcodes using adf mobile 11.1.2.3 ? or when would be the next release date of adf mobile?
I´ve tried to launch zxing via url (barcode app should be installed previously) as you can see in https://code.google.com/p/zxing/wiki/ScanningFromWebPages, but i fail getting the scan code.
So i do not know if my try could be a solution or adf mobile definitively do not let to read barcodes.
thanks for your attention.

IMAQ Read Barcode.vi

Does anyone have documents or information on the algorithms used from IMAQ REad BArcode.vi?
I need to write a report about my project and I dont know how the VI decode the barcode.
Is there anyway I can find out?
Best regards,
Krispiekream

Hi krispiekream,
I can't tell you specifics, but you can expect with any 1D barcode that it's doing edge detection across it and measuring the distances. The distances and thickness of lines specify characters. I'd recommend a search through Wikipedia as to the different barcode types listed in the help for that VI.

Slow response when reading barcode in RFID

Hi All.
We're facing trouble when scanning barcode in some RFID transactions. When reading barcode for example, Material number is written very slow, it takes aproximately 2 seconds to write each character, so, for a string for 15 characters it takes more less 30 seconds to write the full code scanned.
We're using terminal cm9090-g, Windows Mobile 5 release 1.35 and running SAP ECC 6.0.
If you need any further information, please let me know.
Please advice.

No, phones do not have upgradeable RAM. Actually, IMO that was the mis-engineered fault of the N97, for all its capabilities, its hampered by too little RAM for too many applications. It would take quite a little knowledge of the quirks of Symbian to get it to run smoothly.
For example, choosing the right combination of widgets. Obviously if your widgets comprise of two shorcut bars, music player, calendar and contacts, this would use very little RAM, compared to a combination of contacts (withh RSS), Accuweather, Facebook, Email and Shortcuts.would eat up more RAM since Facebook and Accuweather and the Email would always be running.
When you get the app called KillMe, kill certain tasks which you do not use. For example, do you use handwriting recognition? No? Then Kill peninputmanager. What about Voice Commands? Kill Voice Command Manager. Things like that could ease up on your RAM. Also, dont worry about accidentally Killing something, since under the "A" tab, which is the one where the safe to Kill operations are, that's where you do your killing. Also the apps you killed will work again once you restart the phone.

Re: ADF Mobile: Reading barcodes from camera

Hi there!
Could you describe please, how do you integrate zxing in adf mobile? I think to open the camera using DeviceFeatures DataControl and then try to decode the image captured previously with Java but i do not get loading zxing classes in my android emulator device.

How to read barcode?

Hi,
In my application, we have a requirement of reading barcodes and generating barcodes for shipping lables. Do you have any idea about how to do this in a web application?
Thanks in advance
Regards,
Challa.

Hi rayudu,
We have a custom transaction in SAP to read a barcode tag, but we don´t have any configuration or code to get it. The software of reader makes all work.
You only have to configurate the reading device to simulate the entry of data in SAP, and then execute the wished process.

How to read 'Barcode' in Adobe PDF Forms?

Hi Everybody,
I have a scanned pdf of 20 pages. There is a barcode in every page in a serial order like in first page it is 545001 in second page it is 545002 and in third page it is 545003 and so on. I want to automate a process sothat i can know that all the barcodes are in serial order or not. Or, I could know whether it is tempered or not.
Please tell me. How i can do this using Adobe Acrobat or Adobe LiveCycle?
Is there any features in acrobat or livecycle?
Thanks,
Manjeet

It is an offline form.
We are consuming the web service in Form to create a PR.
However we also need the user to attach some documents before it actually clicks on the "Create PR" button.
User can attach the file through "Attachments" facility provided on Adobe Reader.
Our problem is how to check whether user has attached the documents or not. If the documents are attcahed then how to read them using JavaScript?
Thanks,
Taha

Read BARCODE in PDF file

Hi! I've a requirement to read some barcodes inside PDF files. I actually can read from images, but can't find how to read them from a PDF. Someone has done this? Or maybe some suggestions to convert PDF to image, in that way I can read the code from the generated imaged?
Best regards!

I believe the iText library lets you read PDFs in Java. You can google it. Or for that matter, google java pdf library.
Once you know how to extract the barcode image from the PDF, it will be the same steps you use to read the image normally. If it's stored as something other than an image, that should be documented in the library's docs.

How can I generate and read BarCodes?

Do you know where I can download a VI that can generate a bar code.
I use LabVIEW 6.1.
Regards
Richard Pettersen

The easiest way to generate a bar code is to just use a bar code font in a string indicator. I've got a 3 of 9 font on my system that I don't know where it came it from (printer or Word installation maybe). Other formats are available - do a web search for barcode fonts. If you need to read bar codes, get a keyboard wedge type. These go between the keyboard and pc and give text input just like typing. No special VIs are required. Good luck.

Read barcode or QR code inside image and save it in the file as metadata

Maybe someone can help me with this question...
All product photos contain a barcode or QR-code. It is visible inside the image.
The customer is looking for a way (a plug-in) that is able to find the code inside the image, read it and place the information found in a preselected Metadata field of the image it self.
Can anyone tell me if this already exists or is there anyone who can develop it? If yes, than please let me know
Regards,
Pieter

It would be absolutely incredibly useful to me as a volume photographer, and I suspect other photographers too. Anybody who needs to link data to images or catalogue images would be the target market.
Let me outline a conversation that I had with a Lightroom developer at TTG recently, who unfortunately can't help me...
Original Conversation is at: Lightroom 6 (Page 1) — General — Community @ The Turning Gate (post 17 onwards).
Automatically matching and syncing data to pictures is a huge software industry in its own right, believe me.
As a school photographer (though not solely), matching student IDs to their pictures makes everything so much easier and is vital to update student record databases with images of pupils. But it's also very relevant to other sectors such as events and sports photographers. Imagine if this data could be incorporated into TTG database search facility.... (Do we have a swoon smiley?)
Several pieces of commercial software is available, but most rely on the camera being permanently tethered to a laptop and using a barcode scanner to renames files as they come in. This is a crap, restrictive system but is the one the vast majority of people use. An example of this is the Australian Timestone software (http://timestonesoftware.com) which is very popular, but runs into the thousands of UK Pounds for a licence.
An American photographer called Mike Fulton wrote a piece of software called fotovelocity.net which does exactly what I prefer - to photograph the pupil with a barcode somewhere in the image that later gets read by the software and data appended to the metadata of the image. This is slightly cheaper than Timestone, but still runs into the thousands and he not interested in dealing with anybody outside the US.
If Lightroom can read and guess faces to add naming data, then it must surely be an easy upgrade to read an easily scannable QR code?
and ...
Has to be relevant to more than just me, surely?
Imagine all the events / dance meets / clubs / nurseries / schools / football photographers that would use this. Admittedly, this is all volume 'hot-dog' photography and not the artistic side, but it puts a fairly nice roof over my head.
With schools I get a database beforehand, but for most events you don't need to know anything about the attendees to the event beforehand, as you just print out labels that have qr codes with sequenced numbers on them which the portrait subject (or their parents) then keep. They then either visit a printing booth and type the code or take it home and type the code into their browsers and #kabam# up comes their images for purchase. How they run it so that only the first image has the barcode visible yet all subsequent images retain the data from the first image until another barcode is detected I don't know. I guess it must be that a numeric sequence must also be appended to the data from the barcode.
It's a wonderful system for photographers, which is why it costs megabucks.
I will admit though, that the commercial software tends to lab integrate as well, so there is more than just barcode reading. Unfortunately, this ties you in to the system that your preferred lab uses, usually Timestone in the UK, and hence why people have to pay those silly license prices.
If you need a sample image with a QR code in just let me know.
Maybe fotoveolcity instructional videos may give you an impression of how this type of software flows and performs.

Hi Ankit
I dont know if you have NI's Vision Builder for Automated Inspection, it has a function to do Barcode reading, it is very convenient tool to use with lot of good examples.
Kudos are welcomed
