Generating PPTX with pptxgenjs

This pptxjs library allows to generate pptx.

I’ve used this module in a php application (running the nodejs with exec function) : if you want to generate a pptx based on an existing template containing a logo for example,
it will keep the content. I’ve been trying several php libraries and it was not possible to keep the template content.
