Alignment combinators specialized for two dimensions. See Diagrams.Align for more general alignment combinators.

The basic idea is that alignment is achieved by moving diagrams'
local origins relative to their envelopes or traces (or some other
sort of boundary). For example, to align several diagrams along
their tops, we first move their local origins to the upper edge of
their boundary (using e.g. `map `

), and then put them
together with their local origins along a horizontal line (using
e.g. `alignTop`

`hcat`

from Diagrams.TwoD.Combinators).

# Absolute alignment

## Align by envelope

alignL :: (Alignable a, HasOrigin a, V a ~ R2) => a -> a Source

Align along the left edge, i.e. translate the diagram in a horizontal direction so that the local origin is on the left edge of the envelope.

## Align by trace

snugTL :: (Fractional (Scalar (V a)), Alignable a, Traced a, HasOrigin a, V a ~ R2) => a -> a Source

snugTR :: (Fractional (Scalar (V a)), Alignable a, Traced a, HasOrigin a, V a ~ R2) => a -> a Source

snugBL :: (Fractional (Scalar (V a)), Alignable a, Traced a, HasOrigin a, V a ~ R2) => a -> a Source

snugBR :: (Fractional (Scalar (V a)), Alignable a, Traced a, HasOrigin a, V a ~ R2) => a -> a Source

# Relative alignment

alignX :: (Alignable a, HasOrigin a, V a ~ R2) => Double -> a -> a Source

`alignX`

and `snugX`

move the local origin horizontally as follows:

`alignX (-1)`

moves the local origin to the left edge of the boundary;`align 1`

moves the local origin to the right edge;- any other argument interpolates linearly between these. For
example,
`alignX 0`

centers,`alignX 2`

moves the origin one "radius" to the right of the right edge, and so on. `snugX`

works the same way.

snugX :: (Fractional (Scalar (V a)), Alignable a, Traced a, HasOrigin a, V a ~ R2) => Double -> a -> a Source

See the documentation for `alignX`

.

alignY :: (Alignable a, HasOrigin a, V a ~ R2) => Double -> a -> a Source

Like `alignX`

, but moving the local origin vertically, with an
argument of `1`

corresponding to the top edge and `(-1)`

corresponding
to the bottom edge.

snugY :: (Fractional (Scalar (V a)), Alignable a, Traced a, HasOrigin a, V a ~ R2) => Double -> a -> a Source

# Centering

centerX :: (Alignable a, HasOrigin a, V a ~ R2) => a -> a Source

Center the local origin along the X-axis.

centerY :: (Alignable a, HasOrigin a, V a ~ R2) => a -> a Source

Center the local origin along the Y-axis.

centerXY :: (Alignable a, HasOrigin a, V a ~ R2) => a -> a Source

Center along both the X- and Y-axes.

snugCenterX :: (Fractional (Scalar (V a)), Alignable a, Traced a, HasOrigin a, V a ~ R2) => a -> a Source

snugCenterY :: (Fractional (Scalar (V a)), Alignable a, Traced a, HasOrigin a, V a ~ R2) => a -> a Source

snugCenterXY :: (Fractional (Scalar (V a)), Alignable a, Traced a, HasOrigin a, V a ~ R2) => a -> a Source
