Group: Forum Members Posts: 23, Visits: 306	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
