# Reading a Bar Code

This code snippet shows how to read bar codes.

## C++

```cpp
#include <eVision/EasyBarCode/EasyBarCode2/EBarCodeReader.h>
```

```cpp
using namespace eVision;

// Image constructor
EImageBW8 srcImage;

// Bar code reader constructor
EasyBarCode2::EBarCodeReader reader;

// Set the max number of bar codes to find
reader.SetMaxNumCodes(6);

// Read the barcodes in the source image
std::vector<EasyBarCode2::EBarCode> results = reader.Read(srcImage);

// Get decoded string
std::string decodedString = results[0].GetDecodedString();
```
