1, download the zxing on the http://zxingnet.codeplex.com/site. NET third-party libraries2, the download after decompression can see there are different. NET version of the DLL file, referencing the correct DLL in your project3. Then reference the System.Drawing assembly in your project4. In the window where you need to generate the QR code, add the code// Reclaiming Objects [DllImport ("gdi32")] Static extern int DeleteObject (IntPtr o); /** *

() : createTable(); $(element).appendTo(this); }); After modification, you do not need to specify the render parameter. If canvas is not supported, table is used. the disadvantage of using canvas is that it cannot be displayed during webpage printing... there seems to be a solution to this problem. I didn't find it. I used the table directly. However, printing still seems problematic. Js has a problem, so zxing can only be used

Android Zxing QR code scanning image stretching, In this project, the QR code scanning is integrated with zxing, and the image on the scanning interface is obviously stretched and deformed. Based on past experience, this problem is generally caused by misplacement of x and Y axes. The problem of x and Y axes can be solved. Because of this problem, many people have encountered it before and shared it online,

Zxing portrait screen switch android The ZxingDemo downloaded on google is in the landscape status. In Androidmanifest. xml, I simply change Activity to a vertical screen. android: screenOrientation = "portrait" Although the screen is positive, the shooting screen displayed on the screen is still horizontal. I checked some online materials and manually debugged them. Here is a summary Steps: 1) In AndroidManifest. xml, modify the screenOrientation o

IOS QR code scan through ZBar ZXing and other third-party libraries, zbarzxing There are many open-source libraries for scanning QR codes, such as ZBar and ZXing. How to Use ZBar: Download ZBar SDK Address https://github.com/bmorton/ZBarSDK ZBarSDK is an open source SDK that implements the identification and reading of various bar codes, including EAN-13/UPC-A, UPC-E, EAN-8, Code 128, Code 39, Interleaved

I want to use the Android mobile phone to scan QR code and bar code. I went online to gogole and found an open-source library zxing, which can fully implement the functions I needed. After checking out SVN, it's really big (Android version) and has many functions. The functions I want to achieve in my project are scanning and decoding QR codes and bar codes. Therefore, zxing is simplified. Project Struc

First of all, we need to import the zxing jar file, then copy the required resource files and put in the resource files that we need to add, and copy out the necessary related files of the source code. Make certain changes to the layout file, and then modify the code in Captureactivity and Viewfinderview.

It has to be said that the application of QR code is more and more extensive.
