Hi Elvira,

This issue has been fixed in one of the SPs - we just tested with version 12.2.6.12 with the following code:

NChart chart = nChartControl1.Charts[0];
MemoryStream stream = new MemoryStream();
nChartControl1.ImageExporter.SaveToStream(stream, new NEmfImageFormat());
stream.Seek(0, SeekOrigin.Begin);
FileStream fs = new FileStream("c:\\test.emf", FileMode.OpenOrCreate);
byte[] bytes = stream.ToArray();
fs.Write(bytes, 0, bytes.Length);
fs.Close();

and it works OK. In short you need to download the latest service pack and install it.

Let us know if you meet any problems.

Best Regards,

Hi!

I'm trying to save chart control image to stream:

MemoryStream ms = new MemoryStream();
_chart_control.ImageExporter.SaveToStream(ms, new NEmfImageFormat());

But SaveToStream method throw NotSupportedException with message "Specified method is not supported".

Using other image formats such as NXamlImageFormat, NSvgImageFormat, doesn't produce this error.

What's happening with NEmfImageFormat?
