  See attached pdfs
  
  This causes low res: PrintToPdf = true
  
  This cause high res: PrintToPdf = false
  
  But PrintToPdf = false pops up the save to file dialog each time.
  
  How can I get HIGH res with PrintToPdf = true ???

                     var printSet = new PrintInfo
                      {
                          NoPrinterSetting = nop,
                          Centering = Centering.Horizontal,
                          EnhancePreview = true,
                          Margin = new PrintMargin(50,50,50,50,5,5),
                          Header = $"Template {ReviewSheet.FileName}",
                          Footer = $"Created {DateTime.Now:yyyy-MM-dd HH:mm:ss}",
                          PrintToPdf = true,
                          Printer = "Microsoft Print to PDF",
                          PdfWriteMode = PdfWriteMode.New,
                          PdfQualityMode = QualityMode.High,
                          PrintShapes = true,
                          BestFitWithSpan = false,
                          BestFitCols = false,
                          BestFitRows = false,
                          ShowBorder = false,
                          ShowColor = true,
                          ShowGrid = false,
                          OutlineBorderClipped = true,
                          ShowColumnFooter = PrintHeader.Hide,
                          ShowRowHeader = PrintHeader.Hide,
                          ShowShadows = false,
                          ShowColumnHeaders = false,
                          ShowRowHeaders = false,
                          PdfFileName = Path.ChangeExtension(Path.Combine(folder, $"{Path.GetFileNameWithoutExtension(ReviewSheet.FileName)}-{sheet.SheetName}-{DateTime.Now:yyyyMMdd-HHmmss}"), ".pdf")
                      };
                      sheet.PrintInfo = printSet;

  Hi Niels,

  This is a known issue. [Internal Tracking ID: SPNET-32455] The developers have provided Spread.NET v18 as an ETA for the fix of this issue.

  We request you wait for the release to be publicly available in order to get the fix of this issue.

  Thanks & Regards,
  
  Aastha

  Hi Aastha.
  
  I would appreciate if EMF graphics format is supported in
  
  FpSpread.PrintSheet
  
  SheetView.SaveImage
  
  SheetView.AddShape
  
  I expect that would solve the resolution graphics issues I have
  
  Best regards,
  
  Niels

  Hi Niels,

  We discussed your suggestion with the developers. According to them, exporting spread to EMF does not seem feasible currently as will require too many efforts. Also, this functionality is not even supported by Excel.

  Since the fix of this issue has been included in v18, the developers have recommended upgrade to v18 build, when it will be available.

  Thanks for understanding.

  Kind Regards,
  
  Aastha

  Hi Aastha, Thank you for the answer. I wrongly thought EMF was supported by Excel. Sorry for that.
