Functions ¶

func Advance ¶

func Advance(r rune) float64

Advance returns the glyph advance in thousandths of an em, or 500 if it is unknown.

func AdvanceBold ¶

func AdvanceBold(r rune) float64

AdvanceBold returns the bold glyph advance, or 500 if it is unknown.

func Kern ¶

func Kern(a, b rune) float64

Kern returns the adjustment between adjacent glyphs in thousandths of an em. Negative values move glyphs closer together. Values come from Adobe Helvetica's phvr8a.afm KPX pairs.

func Measure ¶

func Measure(s string, size float64) float64

Measure sums glyph advances and kerning, then scales the result to points.

func MeasureBold ¶

func MeasureBold(s string, size float64) float64

MeasureBold sums Helvetica-Bold advances and scales the result to points.

func Supports ¶

func Supports(r rune) bool

Supports reports whether Helvetica/WinAnsi can represent the rune.

func WinAnsiByte ¶

func WinAnsiByte(r rune) (byte, bool)

WinAnsiByte maps a rune to its WinAnsi byte and reports whether it is representable.
