Intersect Infinite Straight Lines with a Window
Description
Take the intersection between a set of infinite straight lines and a window, yielding a set of line segments.
Usage
clip.infline(L, win)
Arguments
L |
Object of class |
win |
Window (object of class |
Details
This function computes the intersection between
a set of infinite straight lines in the plane
(stored in an object L
of class "infline"
created by the
function infline
) and a window win
.
The result is a pattern of line segments. Each line segment carries a
mark indicating which line it belongs to.
Value
A line segment pattern (object of class "psp"
)
with a single column of marks.
