Thanks for inquiring Aspose.Slides.
I have observed your requirements and like to share that the code samples in documentation are actually fetched from gist repository of Aspose.Slides that is hosted on Github. I am able to see the code samples in examples without any issue and request you to please try again on your end. Please observe this image in which the code samples are visible.
