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

Hi Irina,
You need to move the current position in the stream to its begin position (instead of the end) and it should be OK:
var memoryStream = new MemoryStream(); nChartControl1.ImageExporter.SaveToStream(memoryStream, new NSize(500, 500), NResolution.ScreenResolution, new NEmfImageFormat());
memoryStream.Seek(0, SeekOrigin.Begin); var image = Image.FromStream(memoryStream);
