Hello,

I am using Aspose.slides 25.5 to convert PPT to PDF. I am attempting to convert a PPT that contains a mathematical equation inserted in it to PDF but, the conversion fails with below exception:

Blockquotecom.aspose.slides.exceptions.ArgumentException: The required font “Cambria Math” was not found.

Please find the example PPT here:

I am using RockyLinus OS where CambriaMath font is not available, so I have added a substitution rule in the java code to substitute Cambria Math font to STIX Two Math font which is available on the machine.
