# Reading a Grid of Bar Codes

This code snippet shows how to read bar codes that are disposed in a 5 by 3 grid with 10% overlap between grid cells.

## C++

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

```cpp
using namespace eVision;
EImageBW8 srcImage;
ERectangleRegion gridRegion;
EasyBarCode2::EBarCodeReader reader;

// Reading succeeds
EasyBarCode2::EBarCodeGrid grid = reader.Read(srcImage, gridRegion, 3, 5, 0.1f);

std::vector<EasyBarCode2::EBarCode> codesMiddleCell = grid.GetResults(1, 2);
```
