# Convert colors using LittleCMS

Uses LittleCMS to convert the image's color space.

## Instruction

Converts a CMYK image to RGB format using LittleCMS color management engine (default) and saves the result.

## Code Snippet

```csharp
using (var bitmap = new Bitmap("Copenhagen_CMYK.jpg"))
{
    // LittleCMS is a default color management engine, so no need to specify it
    // bitmap.ColorManagement.ColorManagementEngine = ColorManagementEngine.LittleCms;
    bitmap.ColorManagement.DestinationProfile = ColorProfile.FromSrgb();
    bitmap.ColorManagement.Convert(PixelFormat.Format24bppRgb);
    bitmap.Save("ConvertColorsLittleCms.jpg");
}
```

## Explanation

The following code:

- Reads the CMYK image (`Copenhagen_CMYK.jpg`) using `Bitmap`.
- Sets the destination color profile to `sRGB` using `ColorProfile.FromSrgb()`.
- Converts the image to RGB format with color management applied through LittleCMS (default engine).
- Saves the resulting image as `ConvertColorsLittleCms.jpg` after the conversion.
