I am getting the following error when trying to save a diagram page as file type EMF (Aspose.Diagram v184.108.40.206):
Value cannot be null.
Parameter name: encoder
Aspose.Diagram.Saving.ImageSaveOptions imageSaveOptions = new Aspose.Diagram.Saving.ImageSaveOptions(SaveFileFormat.EMF);
for (int p = 0; p < diagram.Pages.Count; p++)
if (diagram.Pages[p].Background != Aspose.Diagram.BOOL.True)
imageSaveOptions.PageIndex = p;
using (System.IO.MemoryStream imageStream = new System.IO.MemoryStream())
imageContent = imageStream.GetBuffer();
Hopefully I’m just missing something obvious?
