Diagrams.Layout.Wrap

An algorithm for filling space in a fashion akin to word-wrapping.

wrapDiagram :: (HasLinearMap v, InnerSpace v, OrderedField (Scalar v)) => ([(v, Diagram b v)], [Diagram b v]) -> Diagram b v

wrapDiagram post-processes the results of wrapOutside / wrapInside into a Diagram of the result. This only works when applying them to a list of diagrams.

wrapOutside :: (Enveloped a, v ~ V a, InnerSpace v, OrderedField (Scalar v)) => (Point v -> Bool) -> [v] -> Point v -> [a] -> ([(v, a)], [a])

wrapOutside is the same as wrapInside, but with an inverted predicate.

wrapInside :: forall a v. (Enveloped a, v ~ V a, InnerSpace v, OrderedField (Scalar v)) => (Point v -> Bool) -> [v] -> Point v -> [a] -> ([(v, a)], [a])

fillInside greedily wraps content to fill a space defined by a predicate. It is passed a list of vectors which express the order of dimensions to be filled. In other words, wrapping RTL text is done by passing in [unitX, unitY], to first exhaust space horizontally, and then vertically.

Note that this function does not guarantee that there are not points inside each positioned item for which the predicate is False. Instead, only the corners of the bounds, along each axii, are used.
