Many Thanks,

pptx.save(new FileOutputStream("sample.pdf"), SaveFormat.Pdf);

Hi Pooja,

Hi Pooja,

I have observed your PDF file and it seems you may have used fonts missing on your end where you are trying to export PDF. Following fonts have been used in your presentation.

  • Arial
  • StarSymbol
  • Arial Black
  • Wingdings
  • Gill Sans MT

Please make sure if the required fonts are properly installed on your machine. You can also load the fonts externally in your application without installing them. You can place the used fonts in some directory and load the fonts externally using FontLoader in your application by passing the address of directory where you have placed used fonts. Please share if there is still an issue on your end.

Best Regards,

Issue got resolved.

Thank you
