Two years ago when I looked at Scribus I decided not to use it as all the image handling seemed to be pixel-only. I must have vector images in the PDF output, though.
I have noticed that there is a way to import vector images (SVG for instance) that get translated to Scribus vectors. This is of course an option. I also noticed that on export to PDF there is an experimental option to embed EPS/PDF. Is that what I think it is? Is it possible to embed PDF vector images in my document and then on export to PDF get these embedded?
If so, the main reason for using Adobe InDesign has disappeared and I can consider moving my projects from InDesign to Scribu (which I would like to as I do not want to get locked in to Adobe's subscription scheme).
