QR code scan Android Zxing image stretching Solution Zxing is a QR code scanning project provided by google. By default, the image is stretched after the screen is converted to a portrait. The solution is as follows: Zxing modifies Void initFromCameraParameters (Camera camera) Method Add Log. d (TAG, "Screen resolution:" + screenResolution ); Point screenResolu

I recently developed a QR code parsing module. Google's open-source project Zxing The Flash function added to Zxing is as follows: In the CameraManager class under the com. xxx. xxx. Zxing. camera package Add code: // OpenLight enables the flashlight. // OffLight is to turn off the flashlight Public void openLight () {if (camera! = Null) {parameter = ca

Zxing is an open source multi-format 1d/2d barcode image Processing Library, implemented in Java. The point is to use the built-in camera on the phone to scan and decode the barcode on the device without communicating with the server. However, the project can also be used to encode and decode barcodes on desktops and servers. These formats are currently supported: Upc-a and UPC-E EAN-8 and EAN-13 Code 39

Two-dimensional code everywhere, sweep a sweep there are gifts Oh, now two-dimensional code is so popular, presumably we are not very clear how the two-dimensional code is generated, now small series by sharing this article to help you learn two-dimensional code generation method. In fact, this feature is mainly used by the jar published by Goggle. 1, two-dimensional code generation Add the Zxing-core.jar package to the classpath. The generation o

Zxing: key code for customizing and modifying the QR code Official source code: http://code.google.com/p/zxing/downloads/list; Decompress the downloaded zxing-x.x.zip file.

Android: Use ZXing to generate a QR code (Logo design can be added) ZXing is an open-source library of Google that can be used to generate and scan QR codes. This article introduces the first part. First: ZXing-related files official: https://github.com/zxing/zxing/releases

Last Friday, when wandering around Google code, I checked Google's open-source projects, Click "Open Source plan" on code.google.com and then click "use Google Code ". You can view the list of all open-source projects of Google. After several pages, I found that a zxing has never heard of it before) It turned out to be a QR code recognition library. Just a few months ago, I was confused about how the anti-counterfeiting code on the train ticket was m

二维码在我们生活中随处可见。在我眼里简直能够用“泛滥”来形容啦。那怎样在我们Android项目中扫描识别二维码或生成二维码图片呢？我们通常使用的开源框架是zxing。在github上的开源地址：https://github.com/zxing/zxing，眼下在做的项目中也用到这个框架， 所以自己做了个demo，方便学习及下次使用。Identify QR code /** * Scan QR Code demo sample */ Public class scancodeactivity extends Activity implements View.

Through the analysis of the "fix barcode" zxing Project source code interpretation (2.3.0 version, Android section), it is now possible to achieve the ultimate goal: streamlining barcode scanner and separating the encoding and decoding into two separate sections for quick integration into your project in the future.CodingIn the previous analysis, the coding section has been disclosed, the core part of only two package. Now share the part to remove the
