ZXing.Net

There are some demos in the repository. Please take a look at the Windows Phone 8 demos. https://zxingnet.svn.codeplex.com/svn/trunk/Clients

First and always: Great work. I'm trying the squeeze the fastest scans possible out of the lib as I have 1 augmented reality scenario that I want to simply overlay data on the QR code during recognition. I'm using the QRCodeMultiReader function. ... [More] But I'm still using the timer based approach to processing the PhotoCaptureDevice stream. I've seen some reference to a newer approach that doesn't use the timer model but haven't found it in the samples. I'm probably just missing something. Lastly any other tips to max performance? Thanks -Todd [Less]

Does Zxing use perspective correction of barcodes? If it does how can I use this method for other things in image? Thank you for your time :)

I have no need or desire to scan from a bitmap; scanning directly from webcam would definately be the best. Any chance you could provide a code example that scans directly from the webcam?

this is the image , the byte of array which are encoded have value from 0x00-0xFE (256 char with null at the end) 0x00-0x01-0x02-0x03- .............0xFD-0xFE-0x00 https://www.dropbox.com/s/zx6juy17jyss6ct/pdf_417.png

I am using Zxing library for windows phone for reading bar code image [code 128].I can successfully read the bar code by using reader.Decode method. I found it from ... [More] [here](http://developer.nokia.com/community/wiki/Generating_and_scanning_barcodes_using_ZXing_on_Windows_Phone)reader.Decode(image);But my latest requirement is to read multiple barcodes from a camera captured image . And i tried with DecodeMultiple method for scanning the code. But it is not succeeds and always getting null result.var decodeMultipleResults = reader.DecodeMultiple(image);I found this code from this [link ](https://zxingnet.codeplex.com/discussions/451898) Also i searched and no other samples found on this for windows phone.Will DecodeMultiple method works on windows phone ?Please provide any information about this.ThanksComments: ** Comment from web user: micjahn ** Please provide a sample image which you tried. [Less]

is it possible to create a filter to remove other graphics from a Picture? - remove Color...The attached Picture is read by a camera which has a special element to Focus. The Color is constant, so an automatic Change Color to tranparent would ... [More] probably enough?Thanks!Comments: You can implement your own pre-processing filter wich you can use before you call the method BarcodeReader.Decode(...). But that's not an issue of ZXing.Net. It's part of your own application. [Less]

You can do the scanning process in the background. But there are some platform specific constraints. Some operations work only in the UI thread. For example if you want to create a BitmapImage you have to do that in the UI thread. At best you will ... [More] get an array of luminance values from your webcam which you can use directly with the method BarcodeReader.Decode(byte[] rawRGB, int width, int height, RGBLuminanceSource.BitmapFormat format) [Less]

Please provide an image of your PDF417 barcode and the original data which is encoded in the barcode.

That's not a question especially related to ZXing.Net. There are other online ressources which are a better source for such general questions. I did a little search for you with google and found a solution at MSDN: How to use the web browser task ... [More] for Windows Phone 8 Perhaps you have to do a little pre-processing before you use the result of the sanning process. There is a ResultParser class in zxing which gives you a parsed result of the raw content if it is embedded in a supported format (like vEvent, vCard, URL, etc.): void _bcReader_ResultFound(Result obj) { // If a new barcode is found, vibrate the device and display the barcode details in the UI if (!obj.Text.Equals(tbBarcodeData.Text)) { VibrateController.Default.Start(TimeSpan.FromMilliseconds(100)); tbBarcodeType.Text = obj.BarcodeFormat.ToString(); tbBarcodeData.Text = obj.Text; var parsedResult = ResultParser.parseResult(obj) as URIParsedResult; if (parsedResult != null) { // do something with ((URIParsedResult)parsedResult).URI } else { // perhaps try the raw content of obj.Text with the WebBrowserTask } } } [Less]
