# Reading a Grid of Matrix Codes

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

## C++

```cpp
#include <eVision/EasyMatrixCode/EasyMatrixCode2/EMatrixCodeReader.h>
```

```cpp
using namespace eVision;
namespace EMC2 = eVision::EasyMatrixCode2;

EImageBW8 srcImage;
ERectangleRegion gridRegion;
EMC2::EMatrixCodeReader reader;

// Reading succeeds
EMC2::EMatrixCodeGrid grid = reader.Read(srcImage, gridRegion, 3, 5, 0.1f);

std::vector<EMC2::EMatrixCode> codesMiddleCell = grid.GetResults(1, 2);
```
