首先看看识别的效果：

1.下载安装 ImageMagick zBar

2.新建头文件

barcode.h

#include <iostream>
#include <string>

//引入头文件
#include ".Barincludezbar.h"
#include ".ImageMagickincludeMagick++.h"


using namespace std;
using namespace zbar;


//加载lib文件
#pragma comment( lib, ".\ImageMagick\lib\CORE_RL_Magick++_.lib" )
#pragma comment( lib, ".\ImageMagick\lib\CORE_RL_MagickCore_.lib" )
#pragma comment( lib, ".\ImageMagick\lib\CORE_RL_MagickWand_.lib" )
#pragma comment( lib, ".\ZBar\lib\libzbar-0.lib" )
