Utilities for working with sizes of two-dimensional objects.

Size and extent of diagrams in R2

Computing sizes

width :: (Boundable a, V a ~ R2) => a -> Double

Compute the width of a boundable object.

height :: (Boundable a, V a ~ R2) => a -> Double

Compute the height of a boundable object.

size2D :: (Boundable a, V a ~ R2) => a -> (Double, Double)

Compute the width and height of a boundable object.

extentX :: (Boundable a, V a ~ R2) => a -> (Double, Double)

Compute the absolute x-coordinate range of a boundable object in R2, in the form (lo,hi).

extentY :: (Boundable a, V a ~ R2) => a -> (Double, Double)

Compute the absolute y-coordinate range of a boundable object in R2, in the form (lo,hi).

center2D :: (Boundable a, V a ~ R2) => a -> P2

Compute the point at the center (in the x- and y-directions) of a boundable object.

Specifying sizes

data SizeSpec2D

A specification of a (requested) rectangular size.

Constructors

Width Double

Specify an explicit width. The height should be determined automatically (so as to preserve aspect ratio).

Height Double

Specify an explicit height. The width should be determined automatically (so as to preserve aspect ratio)

Dims Double Double

An explicit specification of both dimensions.

Absolute

Absolute size: use whatever size an object already has; do not rescale.
