posTextWithMargins :: (Fractional u, InterpretUnit u) => PosObject u -> RectAddress -> LocImage u (BoundingBox u)

advtext :: InterpretUnit u => EscapedText -> LocImage u (Vec2 u)

Single line text, returning its advance vector.

textVector :: (DrawingCtxM m, InterpretUnit u) => EscapedText -> m (AdvanceVec u)

textOrientationZero :: (DrawingCtxM m, InterpretUnit u) => EscapedText -> m (Orientation u)

Build the Orientation of a single line of EscapedText.

The locus of the Orientation is baseline left - margins are added.

charVector :: (DrawingCtxM m, InterpretUnit u) => EscapedChar -> m (AdvanceVec u)

charOrientationZero :: (DrawingCtxM m, InterpretUnit u) => EscapedChar -> m (Orientation u)

Build the Orientation of an EscapedChar.

The locus of the Orientation is baseline left - margins are added.

hkernVector :: (DrawingCtxM m, InterpretUnit u) => [KernChar u] -> m (AdvanceVec u)

hkernVector : [kerning_char] -> AdvanceVec

hkernvector takes whatever length is paired with the EscapedChar for the init of the the list, for the last element it takes the charVector.

hkernOrientationZero :: (DrawingCtxM m, InterpretUnit u) => [KernChar u] -> m (Orientation u)
