Disable Anti-Aliasing for just one font or application?
by John Magolske 14 Apr '23

14 Apr '23

Hi, I'm on Tumbleweed, KDE, and am trying to get set up where my urxvt terminal is displaying a bitmap font without anti-aliasing. In the "Fonts - System Settings" panel Anti-Aliasing is enabled. If I un-check this box to disable, the fonts will no longer be anti-aliased in the urxvt terminal, but everywhere else as well -- which is not what I want. Is there a way to selectively disable anti-aliasing for just urxvt or just the font I'm using there? This would be the PragmataPro font, which does have nice bitmaps. But I'm not finding a way to selectively turn off anti-aliasing for it. In ~/.Xresources I have: URxvt.font: xft:PragmataPro:pixelsize=34:antialias=false:hinting=1:hintstyle=hintmedium In ~/.config/fontconfig/rendering-options.conf I see:   <match target="pattern" > <edit name="force_bw_monospace" mode="assign"> <bool>true</bool> </edit> </match> ...but not sure if anything can be done with that, as this is a DO NOT EDIT generated file, which points to /etc/sysconfig/fonts-config ... so I tried editing that file, changing the following option from "no" to "yes" : # Force black and white rendering. Fonts will not get smoothed with # the benefit of high contrast betwen font and background. # #FORCE_BW="no" FORCE_BW="yes" and then ran the fonts-config command, but this made no difference. Any suggestions re how to selectively turn off anti-aliasing? Thanks for any help, John -- John Magolske http://b79.net/contact
