XML to PNG(PDF) converter

Hi all,

I work for a third party score app and we are looking for a way to render XML files in-app (the is developed with Unity, in C#). I noticed that Musescore is offering this option. but I couldn't find the exact part of code which allows to do that. I would be grateful if someone could point me to the piece of code in the Musescore opensource project.

Best,
Alexis
