A default diagram-adjustment implementation for two-dimensional diagrams, useful for backend implementors.

- adjustSize :: SizeSpec2D -> R2 -> Transformation R2

adjustDia2D :: Monoid m => (Options b R2 -> R2) -> b -> Options b R2 -> AnnDiagram b R2 m -> AnnDiagram b R2 mSource

`adjustDia2D`

provides a useful default implementation of
the `adjustDia`

method from the `Backend`

type class.

As its first argument it requires a method for extracting the requested output size from the rendering options.

It then performs the following adjustments:

- Set some default attributes (in case they have not been set):
- Line width 0.01
- Line color black
- Font size 1
- Freeze the diagram in its final form
- Scale and translate the diagram to fit within the requested size

adjustSize :: SizeSpec2D -> R2 -> Transformation R2Source

`adjustSize spec sz`

returns a transformation which can be
applied to something of size `sz`

to make it the requested size
`spec`

.
