#2139 — Does gs default to DIN A4 in non-US locales?

I've been trying to imagine the correct semantics for selecting
the default dimensions of the graphics for xpost. And the 
obvious first question is: how does ghostscript do it?

So, does gs default to DIN A4 in non-US locales?
Where do you configure that kind of stuff?

In the PostScript?

In Debian, at least, the system default is in /etc/papersize and
Ghostscript reads it from there.

Awesome. Now the bonus question: what about on Ms Windows?

I think the answer given above is wrong.

The file
http://www.ghostscript.com/doc/9.15/Use.htm#Change_default_size
sais:
"You can change the installed default paper size on an installed version
of Ghostscript, by editing the initialization file gs_init.ps. This file
is usually in the Resource/Init directory somewhere in the search path.
See the section on finding files for details.

Find the line

    % /DEFAULTPAPERSIZE (a4) def

Then to make A4 the default paper size, uncomment the line to change
this to

    /DEFAULTPAPERSIZE (a4) def

For a4 you can substitute any paper size Ghostscript knows.

This supecedes the previous method of uncommenting the line % (a4) ....

Sometimes the initialization files are compiled into Ghostscript and
cannot be changed.

Not really, but it is incomplete. Ghostscript sets the default paper 
size using libpaper (http://pkgs.fedoraproject.org/cgit/libpaper.git/). 
It is libpaper who provides GS with the default paper size. It looks in 
some environments variables and configuration files, of which usually 
only /etc/papersize is set.

Yes, once the default paper size is determined using libpaper, you can 
override it in gs_init.ps.
