pixellate(x, ...)
A pixel image (object of class "im"
).
Spatial object to be converted.
A point pattern (object of class "ppp"
),

The function 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
),
windows (pixellate.owin
),
and
line segment patterns (pixellate.psp
),
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.
