Recently made a module about two-dimensional code parsingChoose Google's Open source project ZxingAdd Flash features in zxing as follows:In the Cameramanager class under the Com.xxx.xxx.Zxing.camera packageAdd code:Openlight is to turn on the flashOfflight is to turn off the flash public void Openlight () { if (camera! = null) { parameter = camera.getparameters (); Parameter.setflashmode (parameters.flash_mode_torch

Zxing Vertical Screen Switch AndroidZxingdemo downloaded on google is a horizontal screen stateI simply changed the activity to a vertical screen android:screenorientation= "Portrait" in Androidmanifest.xml.The screen is positive, but the shooting screen is still sideways.Checked some online information, combined with their own manual commissioningSummarize here to shareSteps:1) Change the screenorientation of android:screenorientation= "Portrait"2) R

C # WPF uses ZXing to generate the QR code ImageSource, Introduction: To generate a QR code image similar to the following in the WPF form program, you can use the method described in this article. Add steps: 1. Download The zxing. Net third-party library on http://zxingnet.codeplex.com/site 2. Download and decompress the package. You can see that there are dll files for different. Net versions. reference

Referring to the online example, the Zxing sub-project into Xcode, found that the files in the sub-project file not found error, found that the header file is definitely the search directory has problems, so head file directory (sub-project root directory) added to the main project header file search path inside. Check changed several times or reported the same problem, finally found that the original is recursive problem, before joining the path when

Android open-source QR code recognition project zxing landscape screen changed to vertical screen recognition solution, androidzxing I found a lot of methods on the Internet, but there was a problem in the end. After debugging for several hours, I finally solved the problem of portrait screen recognition perfectly. First, you need to have the simplified code of the zxing project. Using the simplified versio

Zxing generates a QR code nested logo and outputs it to the browser, zxinglogo After reading so many blogs and carrying so many code, I wrote my own blog for the first time. I found that even if I used some technology, it is still not easy to express and restate it. I hope I can stick to it. Why is Zxing used? I don't know anything about Google. It is quite easy to get started with the introduction of more

Recent work needs to develop a QR code scanning software (based on open source project zxing), the problems encountered in the record, but also hope to bring you help.1.

First of all, my test scenario is "identify the two-dimensional code printed on paper", look for the QR code in the scan results and identify it, instead of just letting the camera scan the QR code.Zbar and zxing are using their own DLL compiled from GitHub's clone C + + source/interface, which is the default parameterAgain conclusion: measured about thousands of pictures, two of the accuracy of the library is almost (due to the diversity of the pictu
