  Code is very simple.
  
  I Load a .PDF into the C1PdfDocumentSource, Iterate over the Pages, and save each Page as a .tif file. This works great.

  I have a situation where one PDF loses content when exported to .tif. It is like disappearing ink.

  Here is the psudo code:

                  C1PdfDocumentSource.LoadFromFile(Invoice.FilePath)
                  Invoice.FilePages = C1PdfDocumentSource.PageCount
  
                      For IndexPage As Integer = 1 To Invoice.FilePages
                              FilePath = System.IO.Path.Combine(Invoice.FilePath & "." & IndexPage.ToString("000") & ".tif")
  
                                  TiffFilter = New C1.Win.C1Document.Export.TiffFilter()
                                  TiffFilter.FileName = FilePath
                                  TiffFilter.Range = New C1.Win.C1Document.OutputRange(IndexPage.ToString)
                                  C1PdfDocumentSource.Export(TiffFilter)
                                  TiffFilter = Nothing
  

  I have attached the original PDF, the exported .tif pages and a screen shot of the 2 areas that are being lost.

  Please help!

  I was able to narrow it down to the displaying the document in the viewer as well. C1PdfDocumentSource must be the culprit. Here is a snip of that same area of the document in the Viewer.

  Hello John,

  As I see in the document properties, the PDF includes Type3 fonts. However, PDFDocumentSource does not support these fonts. This has been mentioned under the limitations in the documentation: http://help.grapecity.com/componentone/NetHelp/C1Document/webframe.html#PDFDocumentSource-Key-Features.html

  Please try changing the font in your PDF. In case the issue persists, kindly share the document and I’ll assist you further.

  Best Regards,
  
  Esha

  Thanks for the reply. The document is SHARED in the first post (1011076.ZIP).

  Please let me know if there is anything I can do with the fonts to fix this issue.

  Hello John,

  I referred the pdf in “1011076.zip” and hence, observed that the PDF includes Type3 fonts. However, PDFDocumentSource does not support these fonts. Please change the fonts shown below to some other fonts (other than Type3), and then preview the pdf in C1FlexViewer.
  
  

  If the content is lost after this, kindly share the modified pdf.

  Regards,
  
  Esha
