Fonts Used in a Presentation, Custom Fonts, and Corrupted Fonts

[sraman]

Hi Aspose Team,

We wanted to know if the following API existed with Aspose.Slides .NET

• Check true/false if a give font(s) is used inside the presentation pptx

• Since there is an option to upload custom fonts to aspose runtime, is there a way to check if the custom font is valid/corrupted.

  • if in the above case , the custom font is corrupted, will aspose throw an exception.

  • Is there a timeout after which aspose stops processing the loaded custom font, what is the timeout
    value

  • What are the security implications (on the host machine) of loading a possible insecure font into
    aspose

Regards,
Raman

@sraman,
Thank you for posting your questions.

Check true/false if a give font(s) is used inside the presentation pptx

You can get all fonts used in a presentation as shown below

presentation.FontsManager.GetFonts();

and check if a font is in use.
