Graphics.Rendering.Chart.Renderable

This module contains the definition of the Renderable type, which is a composable drawing element, along with assorted functions to them.

Documentation

data Renderable a

A Renderable is a record of functions required to layout a graphic element.

Constructors

Renderable

Fields

• minsize :: BackendProgram RectSize

  Calculate the minimum size of the renderable.

• render :: RectSize -> BackendProgram (PickFn a)

  Draw the renderable with a rectangle, which covers the origin to a given point.

  The resulting "pick" function maps a point in the image to a value.

type PickFn a = Point -> Maybe a

A function that maps a point in device coordinates to some value.

Perhaps it might be generalised from Maybe a to (MonadPlus m ) => m a in the future.

rectangleToRenderable :: Rectangle -> Renderable a

drawRectangle :: Point -> Rectangle -> BackendProgram (PickFn a)

Draw the specified rectangle such that its top-left vertex is placed at the given position

fillBackground :: FillStyle -> Renderable a -> Renderable a

Overlay a renderable over a solid background fill.

addMargins

Arguments

:: (Double, Double, Double, Double)

The spacing to be added.

-> Renderable a

The source renderable.

-> Renderable a

Add some spacing at the edges of a renderable.

emptyRenderable :: Renderable a

embedRenderable :: BackendProgram (Renderable a) -> Renderable a

Helper function for using a renderable, when we generate it in the BackendProgram monad.

label :: FontStyle -> HTextAnchor -> VTextAnchor -> String -> Renderable String

Construct a renderable from a text string, aligned with the axes.

mapPickFn :: (a -> b) -> Renderable a -> Renderable b

Map a function over result of a renderable's pickfunction.
