{
    string filePath = "image.jpg";
    if (gdpictureImaging.IsCMYKFile(filePath))
    {
        // Enable color correction.
        gdpictureImaging.EnableICM(true);
        int imageID = gdpictureImaging.CreateGdPictureImageFromFile(filePath);
        
        gdpictureImaging.SaveAsTIFF(imageID, "output.tiff", true, TiffCompression.TiffCompressionJPEG, 90);
 
        // Release used resources.
        gdpictureImaging.ReleaseGdPictureImage(imageID);
    }
}
