Diagrams.Lens

Description

This module provides utilities for using Control.Lens with diagrams, including orphan instances for the `Wrapped` class.

Synopsis

Documentation

_P :: Iso (Point v) (Point v') v v' Source

Diagrams.Align

_envelopeVMove :: (Monoid a, HasOrigin a, Enveloped a, Num (Scalar (V a))) => V a -> Traversal' a (V a) Source

A singleton `Traversal` for an envelope vector, where modification of the vector moves the origin appropriately. No vector is traversed when the envelope is empty.

This is the same as `_alignedVMove` with `1` as the interpolation parameter.

_alignedVMove :: (Monoid a, HasOrigin a, Enveloped a, Num (Scalar (V a))) => V a -> Scalar (V a) -> Traversal' a (V a) Source

A singleton `Traversal` for an alignment vector, where modification of the vector moves the origin appropriately. No vector is traversed when the envelope is empty.

The interface mimics "Diagrams.Align.alignBy" in that the `d` parameter specifies an interpolation between two extremes of the envelope. `d = 1` is on the envelope along the vector, whereas `d = -1` is on the envelope, away from the vector.

If you need a `Point` instead of a vector, then compose with `_P`.

Diagrams.BoundingBox

_corners :: (HasBasis v, Ord (Basis v), AdditiveGroup (Scalar v), Ord (Scalar v), HasBasis v', Ord (Basis v'), AdditiveGroup (Scalar v'), Ord (Scalar v')) => Traversal (BoundingBox v) (BoundingBox v') (Point v) (Point v') Source

A traversal that either has 0 (empty box) or 2 points. These points are the lower and upper corners, respectively.

_boxExtents :: (HasBasis v, Ord (Basis v), AdditiveGroup (Scalar v), Ord (Scalar v)) => Lens' (BoundingBox v) v Source

A lens that gets the extents of the box. In order to change the extents, this modifies the upper corner.

Diagrams.Core.Types

_location :: (HasLinearMap v, InnerSpace v, OrderedField (Scalar v)) => Lens' (Subdiagram b v m) (Point v) Source

Gets or set the `location` of a `Subdiagram`.

Diagrams.Located

_Loc :: Iso (Located a) (Located a') (Point (V a), a) (Point (V a'), a') Source

Diagrams.Segment

Prism that constructs linear segments. Can also destruct them, if the segment is Linear.

_bezier3 :: Prism' (Segment Closed v) (v, v, v) Source

Prism that constructs cubic bezier segments. Can also destruct them, if segment is a `Cubic`.
