Wumpus.Basic.Graphic.GlyphMetrics

Data types representing glyph metrics loaded from font files.

Documentation

type FontName = String

type CodePoint = Int

A Unicode code-point.

data GlyphMetricsTable cu

NOTE - GlyphMetrics table is parametric on cu - Character unit and not on the usual u.

Constructors

GlyphMetricsTable

Fields

glyph_bounding_box :: BoundingBox cu

glyph_default_adv_vec :: Vec2 cu

glyph_adv_vecs :: IntMap (Vec2 cu)

glyph_cap_height :: cu

data GlyphMetrics

Constructors

GlyphMetrics

Fields

get_bounding_box :: forall u. FromPtSize u => PtSize -> BoundingBox u

get_av_lookup :: forall u. FromPtSize u => PtSize -> CodePoint -> Vec2 u

get_cap_height :: forall u. FromPtSize u => PtSize -> u

buildMetrics :: (cu -> PtSize) -> GlyphMetricsTable cu -> GlyphMetrics

type BaseGlyphMetrics = Map FontName GlyphMetrics

monospace_metrics :: GlyphMetrics

This ignores the Char code lookup and just returns the default advance vector.
