Raw

transitions

Choose a transition with wallr set <path> --effect <name>. Without an explicit effect, wallr uses a linear crossfade.

effect aliases behavior
fade simple crossfade
wipe directional reveal
slide left, right, top, bottom reveal from an edge
wave reveal with a moving edge
grow center, any expand from a point
outer contract toward a point

any chooses a random origin for a circular transition. random chooses a random transition.

options

  • -d, --duration <time>: length, such as 800ms or 1.2s.
  • -o, --origin <preset|x,y>: origin such as center, top_left, or a normalized coordinate pair.
  • -a, --angle <degrees>: sweep angle for wipe.
  • --direction <x,y>: direction for wipe or slide.
  • --easing <curve>: linear, ease_in, ease_out, ease_in_out, or bezier.
  • --from <value> and --to <value>: fade endpoints.
  • --frequency <hz> and --amplitude <value>: wave parameters.
  • --softness <value>: softness of the wipe edge.
