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

class.

_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) vSource

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

# Diagrams.Core.Style

_mkAttr :: AttributeClass a => Prism' (Attribute v) aSource

_mkTAttr :: (AttributeClass a, Transformable a, V a ~ v) => Prism' (Attribute v) aSource

# 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`

.

_mkSubdiagram :: (HasLinearMap v, InnerSpace v, OrderedField (Scalar v), Semigroup m) => Iso' (QDiagram b v m) (Subdiagram b v m)Source

# Diagrams.Located

# Diagrams.Segment

_mkFixedSeg :: (AdditiveGroup v, AdditiveGroup v') => Iso (Located (Segment Closed v)) (Located (Segment Closed v')) (FixedSegment v) (FixedSegment v')Source

_straight :: Prism' (Segment Closed v) vSource

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`

.
