Hello,
I need to export a chart control to EMF image without saving it to a file. The following code fails with System.ArgumentException when Image.FromStream is called.

var memoryStream = new MemoryStream();
nChartControl1.ImageExporter.SaveToStream(memoryStream, new NSize(500, 500), NResolution.ScreenResolution,  new NEmfImageFormat());
var image = Image.FromStream(memoryStream);

What is the cause of the exception and how it can be prevented?
Thank you
