barcode

I am developing windows mobile application to scan a product barcode by using in built camera. Can you tell me something about barcode reader sdk which are supporting windows mobile 7? In Windows Phone 7, with the upcoming Mango update, there will be direct access to the camera feed, without having to take a picture of the barcode. Prior to Mango, there is a library that can be downloaded from Codeplex, called ZXIng (Zebra Crossing). http://silverlightzxing.codeplex.com/ Are you developing for Windows Phone, or Windows Mobile? There is no Windows Mobile 7 - with the complete rewrite, the name

Anyone who knows a good way to generate/create a barcode from a String in Android? If you want to encode on the device instead of calling to a URL, indeed you want ZXing . Look at what it does for the Android client Barcode Scanner in EncodeActivity . tbruyelle You can use the Google Charts API, a simple call to the following url with your text in chl parameter returns an image with the QRcode. http://chart.apis.google.com/chart?cht=qr&chs=150x150&chl=give+me+a+beer 来源： https://stackoverflow.com/questions/2370245/generating-creating-a-barcode-in-android

I wish to develop an application which implements two-way communication with a barcode reader where the application sends back an accept/reject signal to the barcode reader to indicate success or failure and the barcode reader interprets with a different beep, red bulb or whatever (depending on the brand). For this reason using the Keyboard Wedge or one-way communication does not suit this scenario (this use case will have people away from the computer with wireless handheld barcode scanners, so they won't be seeing anything on screen). I think that for this scenario I have to use HID POS, but

Data Matrix barcode support was added to iOS 8 and I'm able to use it to read Data Matrix barcodes if they are black on white (dark on light). However, it never reads a white on black (light on dark) barcode. Reads this fine: Unable to read this: Per Data Matrix ECC 200, light on dark should be supported. Anyone have an idea how to get iOS 8 to read a light on dark Data Matrix barcode? You can invert the colors of your AVCaptureSession in real time, allowing you to read the Data Matrix code. You can use GPUImage to invert the colors. It's fast and plugs in easily. Just invert and let

I was experimenting with ResultPoints which returns the points related to the barcode in the image. For a QR Code, ResultPoints returns a set of 4 points which are the coordinates of the four boxes at each corner of the QR Code. When I experimented the same with a Barcode, it returns two points which denote the width of the barcode. How do I find the bounding rectangle of the barcode? Is there any way by which I can calculate the coordinates of the top left corner and bottom right corner of the barcode using the ResultPoints array? After a bit of research I found the class

Not exactly a programming question, but close. I'll try my luck anyway. The keyboard wedge barcode scanner inserts the translation device between the reader and the keyboard. Data sent through a wedge appears as if it was typed into the computer, while the keyboard itself remains fully functional . Because a computer using a keyboard wedge can't tell the difference between data that is entered by a scanning device, or data that is entered by keyboard typing, a wedge can be used to easily add barcode reading capability to an existing computer without modifying software applications . I'd like

I'm working on a Windows Phone 8.1 Runtime shopping application which needs barcode scanner feature. I'm using the ZXing lib, which is fine. My problem isn't about decoding the picture, ZXing does a great job, but to get the Camera Preview realtime, and feed it to ZXing. After a little research I found this forum https://web.archive.org/web/20150328233747/http://developer.nokia.com/community/discussion/showthread.php/247707-Windows-Phone-8-1-Windows-Media-Capture-API-and-Preview-Frames . Can someone give me a working sample of combining an MFT and ZXing? Or how can I get the preview and handle
