1.92.3 Get methods

line <-angle: origin=[point] -> degrees=real

Return the angle of the line with the positive X-axe in degrees counter clockwise.

line <-distance: to=graphical|point|event, segment=[bool] -> int

If the argument is a point object, this method computes the distance to the the infinitely extended line (if segment is @default or @off) or the line segment if segment is @on.

If the argument is an event object, act as above using the position of the event in the coordinate space of the graphical<-device.

If the argument is a graphical objects, it invokes area<-distance using the areas of both graphicals.

See also graphical->in_event_area.

line <-start: -> point

line <-end: -> point

Unlike normal graphicals, lines are in general not specified using their graphical<-width and graphical<-height but using line<-start and line<-end.

line<-start

line <-intersection: with=line -> point

Return a new point object describing the intersection point of both infinitely extended lines. Fails if the lines are parallel.

line <-length: -> int

Distance between the points line<-start and line<-end. See also point<-distance.
