Details
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
)
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.
Value
- A pixel image (object of class
"im"
).
