QR code generation and parsing toolkit-zxing
Table of Contents 1 Introduction 2. Give an example 2.1 Add dependencies 2.2 Tools 2.3 Testing 3. Summary Today, when I was looking at an open source project, I found a tool class, a simple tool class for generating QR codes. It was very convenient to test it. Although it has not been used in […]
Android uses ZXing to draw gradient color QR codes
Draw QR code A few days ago, I received news that the project was going to be revised, and sure enough, things happened right away. Open Blue Lake and take a look – the QR code with gradient colors from left to right. After thinking about it, I really haven’t done it before, so I […]
Java uses zxing to create QR code with text and logo

Andorid implements QR code generation & scanning based on ZXing
Recently, I encountered the need to scan barcodes, and the process of searching for information was not so smooth. I made a note and recorded these two articles. The predecessors planted trees for future generations to enjoy the shade. Andorid implements QR code generation & amp; scanning based on ZXing Android implements barcode scanning based […]

Move the zxing-cpp example to my project Win32, VC compiles the static library /MT, /MTd and the dynamic link library /MD, /MDd to understand the C++ header file or naming conflict: put it in a separate class.
Why compile the library first instead of using it out of the box like other languages? Because c++ has many modes. Summary: First compile the library and examples without doing anything. Then change the example step by step according to my project type. It is normal to build a project alone. Putting it into the […]
Compile C++ makefile ZXing-cpp to generate barcode, QR code and recognition Retest and verify success vs2022
Download ZXing-cpp source code and vs2022 cmake –help to see the supported vs Why is there no win32? Enter the directory, //create a new compilation directory//generate vs project mkdir build & cd build cmake.. It doesn’t matter if there is a lack of things such as opencv and qt in the middle, I only use […]
Android quickly implements two-dimensional code scanning–Zxing
Reprinted from: https://blog.csdn.net/xch_yang/article/details/81327695 The most commonly used libraries for QR code scanning in Android are zxing and zbar. The address of the zxing project is https://github.com/zxing/zxing, and there are still many people maintaining it. zbar is mainly written in C. If you need speed, you can use zbar, but it is not being maintained at […]
Use zxing3.4.1 framework to add QR code scanning function
1. Add zxing to introduce dependencies Add in build.gradle(module): implementation ‘com.google.zxing:core:3.4.1’ implementation ‘com.journeyapps:zxing-android-embedded:4.2.0’ Since we want to use the camera resource, we also need to add the following three permissions in the tag of the AndroidManifest.xml file: <uses-permission android:name=”android.permission.CAMERA” /> <uses-feature android:name=”android.hardware.camera” /> <uses-feature android:name=”android.hardware.camera.autofocus” /> The first is the CAMERA permission, which allows an […]
