Is there anyway to convert a .sla file to a .pdf directly from the windows or python command line.
(Not from Scribus command line!)
I need this conversion to be done without the user first having to open Scribus at all.
Thanks in advance!
have you googled for "scribus command line"?
https://wiki.scribus.net/canvas/Command_line_scripts
this is a bash script i'm using to create A4 PDFs out of A6 scribus files:

there is a neat trick in there to launch the script from the command line and it then calls itself from inside of scribus.
you will probably need a moder development version to get it to work. and it's easier to get to work on linux or mac os x, rather than on windows.
