Help Required: How can I convert selected slide as image in power point js api ?

This is not directly supported unfortunately. It appears that the only current way to achieve this is to get the full presentation contents (supported in Office.js) and pass the contents to a backend service that can process the PowerPoint into images. For large presentations this becomes painfully slow, even just getting the contents of the presentation can take seconds. Hopefully there are others with the same need, so I will create a feature request in the appropriate forum and post back here.
