- A window (object of class
"owin") or data that can be converted to a window by
This function computes the perimeter (length of the boundary) of the window
w is a rectangle or a polygonal window, the perimeter is the sum of the lengths of the edges of
w is a mask, it is first converted to a polygonal window using
as.polygonal, then staircase edges are removed using
simplify.owin, and the perimeter of the resulting polygon is computed.
A numeric value giving the perimeter length of the window.
