I wanted to render a Scribus .sla file to .pdf and got a warning .pdf embedded. The reason was that I placed a .pdf graphic in an image frame instead of importing it as vector file.
An internet search revealed that .pdf graphics are in fact pixelated if imported as images (or when selecting wrong option); therefore the warning. So I imported a .pdf as well as a .svg of my graphic using File >> Import >> Get Vector File... and placed it on my document―so far so good.
However I need a hairline around the graphic, i.e. a thin box; this works well with image frames. But for some reason with the "Vector File frame" the options are greyed out:
When I double-click on the graphic, a window opens with an option "edit contour line", but that's something different. I probably could draw a box around the graphic by hand, but I think there might be a better option.
So, how can I make a hairline (or any thin line) around my vector graphic?
I'm using Scribus 1.5.8 on Ubuntu 22.04 LTS.
Update: Just realized that I would run into a follow-up problem, because I want to place another graphic exactly under the first one (it's the legend) and draw the box around both. Perhaps the vector objects should be put together in kind of a frame or so, but I still don't know how.
