            Bug ID: 94824
           Summary: Documentation of scale option in weston.ini manpage
                    not clear
           Product: Wayland
           Version: unspecified
          Hardware: All
                OS: All
            Status: NEW
          Severity: normal
          Priority: medium
         Component: weston
          Assignee: wayland-bugs at lists.freedesktop.org

Hello,

I noticed the scale option in the weston.ini manpage:

http://manpages.ubuntu.com/manpages/xenial/man5/weston.ini.5.html

and googled a bit on it and found the following links:

https://lists.freedesktop.org/archives/wayland-devel/2013-May/009368.html
https://lists.freedesktop.org/archives/wayland-devel/2014-August/016845.html
http://www.phoronix.com/scan.php?page=news_item&px=MTM3NzM

But there does not seem to be any explanation on how exactly the scale option
works in layman's terms.

What exactly does it do?

Does it upscale the image via nearest neighbor filtering?

And why does the manpage says one should use "a value of 2 for outputs with
high resolution"? Why not a value of 3?

I just want to understand how exactly the scale option works and what it does.

Could anyone explain this and update the manpage please?

Regards
