data Doc u

Space is the width of a space in the current font - it is filled in during interpretation.

type TextFrame u = RectAddress -> LocImage u (BoundingBox u)

TextFrame is the result Graphic made from rendering multiple lines of DocText.

render :: (Real u, Floating u, InterpretUnit u) => FontFamily -> Doc u -> RectAddress -> LocImage u (BoundingBox u)

leftAlign :: [Doc u] -> Doc u

centerAlign :: [Doc u] -> Doc u

rightAlign :: [Doc u] -> Doc u

blank :: Doc u

space :: Doc u

string :: String -> Doc u

escaped :: EscapedText -> Doc u

int :: InterpretUnit u => Int -> Doc u

integer :: InterpretUnit u => Integer -> Doc u

float :: (RealFloat a, InterpretUnit u) => a -> Doc u

Specialized version of ffloat - the answer is always rendered at "full precision".

ffloat :: (RealFloat a, InterpretUnit u) => Maybe Int -> a -> Doc u

This is equivalent to showFFloat in the Numeric module.

Like showFFloat, the answer is rendered to supplied precision. Nothing indicated full precision.

(<>) :: Doc u -> Doc u -> Doc u

Concatenate two DocTexts separated with no spacing.

(infixr 6)

(<+>) :: Doc u -> Doc u -> Doc u

(infixr 6)

vcatl :: Doc u -> Doc u -> Doc u

Vertically concatenate - aligning left.
