# Apply LUT

Applies LUT (look-up table) correction.

## Instruction

Apply a custom LUT (Look-Up Table) to an image for color adjustment.

## Usings

```csharp
using Aurigma.GraphicsMill.Transforms;
```

## Code Snippet

```csharp
using (var bitmap = new Bitmap("Chicago.jpg"))
using (var lut = new Lut())
{
    lut.SetPoint(50, 70);
    lut.SetPoint(100, 150);
    lut.InterpolationMode = LutInterpolationMode.Cubic;

    bitmap.ColorAdjustment.ApplyLut(lut);

    bitmap.Save("ApplyLut.jpg");
}
```

## Explanation

The code:

- Creates a LUT and sets specific points for the color mapping (50 -> 70, 100 -> 150).
- Uses cubic interpolation for smoother transitions between points.
- Applies the LUT to the image's color adjustment using `ApplyLut`.
- Saves the color-adjusted image to an output file.
