how to reduce the size of the image in .NET Core

Here this is my code

var stream = new MemoryStream();
await responseStream.CopyToAsync(stream);

stream.Position = 0;
var Result = stream;
byte[] bytes = stream.ToArray();
string Base64 = System.Convert.ToBase64String(bytes);

// get the size of the image
MemoryStream ms = new MemoryStream(bytes);
Image returnImage = Image.FromStream(ms);
Bitmap resizedImage = new(returnImage, new Size(310, 212));
                                              resizedImage.Save(stream, ImageFormat.Jpeg);

VisaItineraryResponse.Pax.ElementAt(paxindex)
                         .Docs.ElementAt(DocIndex).Base64String = Convert.ToString(resizedImage);

I got an exception while using this code

System.Exception: Failed
System.TypeInitializationException: The type initializer for 'Gdip' threw an exception.
System.PlatformNotSupportedException: System.Drawing.Common is not supported on non-Windows platforms. See https://aka.ms/systemdrawingnonwindows for more information.

If you click on the provided link in the exception, it says

Because System.Drawing.Common was designed to be a thin wrapper over Windows technologies, its cross-platform implementation is subpar.

Recommended action

To use these APIs for cross-platform apps, migrate to one of the following libraries:

I have used skiasharp and would recommend it. I can't say how that compares to maui graphics.
