wallpapers in rio
it works. I originally planned on creating a new file,
/dev/background, for this, but then I saw atamariya’s modifications
and decided to use /dev/screen instead. only thing about this
approach is that originally I had planned that reading
/dev/background would return the background that was set, but that
seems rather pointless since you should have access to the image you
set already. no code from atamariya was used as I couldn’t find it
anywhere, and some inspiration was taken from sigrid’s rio
patch. backgrounds in p9bit format (readable by
readimage(2)) are supported, as well as solid colors starting with as
6-digit hex literals starting with ‘#’.
to use, write to /dev/screen:
# setting a bitmap wallpaper
; cp wallpaper.bit /dev/screen
# setting a png wallpaper
; png -9 wallpaper.png >/dev/screen
# setting a solid color wallpaper
; echo '#181818' >/dev/screen
to install:
; cd /sys/src/cmd/rio
; hget https://up.ccf.sh/rioback.patch | patch -p5
