Diagrams.Align

General tools for alignment. Any boundable object with a local origin can be aligned; this includes diagrams, of course, but it also includes paths.

align :: (HasOrigin a, Boundable a) => V a -> a -> a

align v aligns a boundable object along the edge in the direction of v. That is, it moves the local origin in the direction of v until it is on the boundary. (Note that if the local origin is outside the boundary to begin, it may have to move "backwards".)

alignBy :: (HasOrigin a, Boundable a) => V a -> Rational -> a -> a

align v d a moves the origin of a to a distance of d*r from the center along v, where r is the radius along v. Hence align v 0 centers along v, and align v 1 moves the origin in the direction of v to the very edge of the bounding region.

center :: (HasOrigin a, Boundable a) => V a -> a -> a

center v centers a boundable object along the direction of v.
