Diagrams.TwoD.Path.Metafont.Combinators

Description

Combinators to allow writing Metafont-style paths embedded in Haskell, with the usual Diagrams types for points and directions.

Synopsis

Documentation

(.-) :: P2 n -> MFPathData J n -> MFPathData P n infixr 5 Source #

point .- join -. path adds point to the left end of the metafont path, connected by join.

(-.) :: Join n -> MFPathData P n -> MFPathData J n infixr 5 Source #

See .- above.

(.--.) :: P2 n -> MFPathData P n -> MFPathData P n infixr 5 Source #

Add a point to the left of a Metafont path using a simple join. That is, neither direction is specified, and both tensions are 1.

endpt :: P2 n -> MFPathData P n Source #

Terminate the right-end of a Metafont path at the given point.

cyclePath :: MFPathData P n Source #

Wrap the right-end of the Metafont path back to the left-end. When converted to a Diagrams Trail', this will be a Loop.

simpleJoin :: Join n Source #

simpleJoin is the same as mempty, with a more specific type. It is provided for convenience in situations where explicit type signatures would otherwise be needed, such as when building up a join using lenses.

tension :: n -> Join n Source #

A join with both tensions the same.

tensions :: n -> n -> Join n Source #

A join with two tension values.

controls :: P2 n -> P2 n -> Join n Source #

A join with explicit control points. Note that these are in the same coordinate system as the endpoints, not relative to the latter.

leaving :: V2 n -> Join n Source #

A join with the left-end direction specified.

arriving :: V2 n -> Join n Source #

A join with the right-end direction specified.
