line-segment-intersects-box-p

Arguments: end1 end2 box

Returns whether a line segment intersects a box.

end1 and end2 are position objects (see make-position) that specify the endpoints of a line segment, and box is a box object (see make-box). If the objects intersect then true is returned, and otherwise nil is returned.

As usual, position and box objects should contain integers. See also line-segment-intersects-box-x-y-p.
