Re: Xft dpi font scaling
Hi René --
Ar an ceathrú lá de mí na Nollaig, scríobh René Rebe:
since years I use xemacs-beta, currently 21.5.34:
https://t2sde.org/packages/xemacs-beta
Except the lack of updates I am quite happy with that setup, however one
details drives me increasingly crazy. Namely HiDPI font scaling when I
switch between old displays and newer, 4k+ HiDPI, 192++ dpi screens.
;
I have this font selection in my .xemacs/init.el
(set-face-font 'default "Source Code Pro-13") ; or -22 for HiDPI
Ideally I want this -13 to be pt, so that I do not have to edit the file
each time I switch my desk or continue coding on the road.
In fontconfig theory the -13 is pt, so it seems that the underlying library
isn’t handling it correctly.
Googling around suggest others alternative forms which either do not
work in xemacs-beta, or do not prove the situation.
I tried to read the lisp files, but could not find anything that would
help me there either.
Is there anything "pt" like so that a 13pt would result in say 13 pixels
on a low resolution display, and 26 (or whatever) pixels on a HiDPI
screen with the X server dpi set accordingly?
PS: Surprisingly the Xemacs menus and such sale automatically, just not
this most important, main edit buffer, ..?
... except this suggests it does!?
Xft isn’t my bailiwick, and I don’t have a high-DPI screen available to
reproduce ± debug this issue. Stephen?
Best,
Aidan
