USAGE
:
device.xy(wx, wy) world.xy(dx, dy)
dx,dy
:
vectors of x- and y-coordinates in the current device coordinate system.
wx,wy
:
vectors of x- and y-coordinates in the current world or user coordinate system.
VALUE
:
a list with elements named
x
and
y
that give the mapped coordinates, i.e., device coordinates for
device.xy
and world coordinates for
world.xy
.
