Generate PDF very slow

Dear support,


We upgraded the api version to 14.9.0 and found that the save to PDF becomes very slow.
FYI, when save in pptx format, it takes around 2 mins, while in PDF format, it requires 20+ mins.

IPresentation ppt = new Presentation(pptTemplate.getInputStream());

ppt.save(reportPath + filename + ".pdf", SaveFormat.Pdf);

Hi Raymond,


Thank you for the details.

Please share the sample input presentation file with us to further test the issue at our end. We will check it and get back to you.

Thanks & Regards,

Hi support,


Please find the attachment.

Hi Raymond,

Thank you for sharing the template file.

I have checked the PPTX to PDF conversion using your template file and it only takes 23 seconds on my end to convert the file. Please confirm if the shared file is same as you are using at your end? Also, please share your system environment with us i.e. OS, JDK version etc. to reproduce the issue. We will check it and get back to you.

Thanks & Regards,
