How do i take a screenshot from libre impress to add to a writer document?

I am trying to compile a supporting document for a slide presentation i have put together with impress.

How to take a screenshot depends on your operating system. But this is probably not the best way to accomplish your goal. Select the slide you want an image of and choose File > Export.

I ended up using printscreen through onedrive then cropped it before copy and paste to a writer document.thanks
