Hi,

I have a few issues when saving a Powerpoint presentation using SaveToFile(path, FileFormat.PDF).

The Powerpoint presentation is build from scratch using the Spire.Presentation library and has a perfect quality.
When saving the presentation with SaveToFile I see the following issues:

- Incorrect fonts
- Stretched image files

When saving the Powerpoint presentation to PDF using the Powerpoint application, the PDF file is perfect.

Is there any possibility to include the Powerpoint application export to PDF in Spire.Presentation?

Attached are a few examples of the issues.
In the first row, the font is not correct. There are too much spaces between the words.
In the second row, the font is not correct. The source font is Calibri(body).
The images in the second row are strechted
In the last row, the link underline is too thick.

Thanks for your feedback!

Grts,
Laurent Tilquin

Hello Laurent,

Thanks for your inquiry!

Sorry that our Spire.Presentation does not rely on the PowerPoint application when converting PPT to PDF, but only follow the Microsoft PowerPoint standard.

Please make sure that you are using the latest Spire.Presentation for net 6.12.4. If the issues still exist, please provide us with the following information for further investigate, you can also send it to us via email (support@e-iceblue.com). Thanks in advance!

1. Your input files (or the code you used to generated PPT).
2. The target framework of your project (E.g. .netframework 4.8.0).
3. Your project type (E.g. console application).
4. Your running system information (E.g. Win7, 64 bit) and region setting (E.g. China, Chinese).
5. The fonts list of your running system.

Sincerely,
Marcia
