# Convert CMYK to RGB

Converts color space from CMYK to RGB with color management.

## Instruction

Converts a CMYK image without a color profile to RGB using a default color profile and saves the result.

## Code Snippet

```csharp
using (var bitmap = new Bitmap("Copenhagen_CMYK_NoColorProfile.jpg"))
{
    // Assign some default color profile
    if (bitmap.ColorProfile == null)
    {
        bitmap.ColorProfile = new ColorProfile("ISOcoated_v2_eci.icc");
    }

    bitmap.ColorManagement.DestinationProfile = ColorProfile.FromSrgb();

    bitmap.ColorManagement.Convert(PixelFormat.Format24bppRgb);

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

## Explanation

The code:

- Loads the CMYK image ("Copenhagen_CMYK_NoColorProfile.jpg") into a `Bitmap`.
- If the image does not have a color profile, assigns a default color profile ("ISOcoated_v2_eci.icc").
- Sets the destination color profile to `sRGB` using `ColorProfile.FromSrgb()`.
- Converts the image from CMYK to RGB using `ColorManagement.Convert`.
- Saves the result as "PF_ConvertCmykToRgb.jpg" using the `Save` method with the new RGB format.
