Is there an easy way to export a projection as an image?

I use GPlates to build maps. If I want a project as an image (typically as a rectangular map), the only way I know to do so is to take a bunch of screenshots of zoomed in sections of the projection, then stitch them together in an image editor. Is there a easier proper way to do this?

Have you tried the “Export” option?


Somehow, I missed the option to export as an image. Thank you!
