pixellate(x, ...)
"ppp"
),
a window (object of class "owin"
) or
some other suitable data."im"
).pixellate
converts a geometrical object x
into
a pixel image, by measuring the amount of x
that is
inside each pixel.
If x
is a point pattern, pixellate(x)
counts the
number of points of x
falling in each pixel.
If x
is a window, pixellate(x)
measures the area
of intersection of each pixel with the window. The function pixellate
is generic, with methods for
point patterns (pixellate.ppp
)
and windows (pixellate.owin
).
See the separate documentation for these methods.
The related function as.im
also converts x
into a pixel image,
but typically measures only the presence or absence of
x
inside each pixel.
