(.-) :: 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.
