# Profile Sampling

This code snippet shows how to set, retrieve and store the pixel values along a given line segment.

## C++

```cpp
#include <eVision/EasyImage/EasyImage.h>
```

```cpp
using namespace eVision;
// Image constructor
EImageBW8 srcImage;
// ...
// Vector constructor
EBW8Vector profile;
// Get the image data along segment (10,510)-(500,40)
EasyImage::ImageToLineSegment(&srcImage, &profile, 10, 510, 500, 40);
// Set all these points to white (255) in the image
EasyImage::LineSegmentToImage(&srcImage, 255, 10, 510, 500, 40);
```
