extra arguments to as.mask
controlling the pixel resolution
Value
Another object of class "owin" representing the
dilated window.
Details
The morphological dilation of a set $W$ by a distance $r > 0$
is the set consisting of all points lying at most $r$ units
away from $W$. Effectively, dilation adds a margin of width
$r$ onto the set $W$.
The functions dilate.owin and dilation.owin are
identical, and compute the dilation of the window w.
The window w is first approximated by a binary pixel image,
and the arguments "..." are passed to as.mask
to determine the pixel resolution. There is a sensible default.
