Convert a DNG image to JPEG format

[lpmnobre]

Could you help me please to configure a DNG image's conversion to JPEG without changing the original colors?
The DNG file was downloaded from:
https://www.camerafv5.com/pages/raw-samples.php
image: airport1.dng

Here a snippet of my code:

MagickReadSettings settings = new MagickReadSettings { Format = MagickFormat.Dng,  };
var filestream = new FileStream(imageURL, FileMode.Open, FileAccess.Read);
using (filestream)
using (var image = settings == null ? new MagickImage(filestream) : new MagickImage(filestream, settings))
{
    image.Depth = 16;
    image.PhotonsAutoOrientation();
    image.Strip();
    image.Settings.SetDefines(new JpegWriteDefines()
    {
        Extent = (int)maxSizeInBytes / 1024
    } );
 }

Thanks so much!

The problem related to the color background/brightness of the generated JPG was solved when I updated the Magick.Net and Ghostscript libraries.
I should have done this update before posting the issue. I'm sorry about that!

No problem, really appreciate that you came back to respond to your own question.

p.s. What does the PhotonsAutoOrientation extension method do?

The PhotonsAutoOrientation method transforms an image with rotations and flip/flop operations, if necessary, to let it with the TopLeft orientation type.
I think the problem I reported was corrected in the 7.22 version (Remove incorrect GrayScale optimization for ToBitmap).
Thanks so so much for your hard and brilliant work!
