Interface: FontFace

Defined in: core/src/measure/FontEngine.ts:32

Opaque font face handle returned by FontEngine.create()

Properties

_opticalSize?

readonly optional _opticalSize?: object

Defined in: core/src/measure/FontEngine.ts:68

Set when the font has an opsz axis that registration left free: the un-instanced master plus the registered axes, so opticalSizeInstance can pin opsz to the used font size (CSS font-optical-sizing: auto).

base

readonly base: any

max

readonly max: number

min

readonly min: number

variation

readonly variation: Record<string, number> | undefined

---

_raw

readonly _raw: any

Defined in: core/src/measure/FontEngine.ts:34

fontkit font object (private — not meant for direct access)

---

ascent

readonly ascent: number

Defined in: core/src/measure/FontEngine.ts:37

---

capHeight

readonly capHeight: number

Defined in: core/src/measure/FontEngine.ts:39

---

descent

readonly descent: number

strikeoutPosition

readonly strikeoutPosition: number | null

Defined in: core/src/measure/FontEngine.ts:61

---

strikeoutSize

readonly strikeoutSize: number | null

Defined in: core/src/measure/FontEngine.ts:62

---

typoAscent

readonly typoAscent: number | null

Defined in: core/src/measure/FontEngine.ts:43

OS/2 typoAscender / typoDescender (font units) — null when the font has no OS/2 table.

---

typoDescent

readonly typoDescent: number | null

Defined in: core/src/measure/FontEngine.ts:44

---

underlinePosition

readonly underlinePosition: number | null

Defined in: core/src/measure/FontEngine.ts:59

Decoration geometry in font units, font-table signs: post.underlinePosition (top of the underline, negative = below the baseline) / underlineThickness, OS/2.yStrikeoutPosition (top of the strikeout, above the baseline) / yStrikeoutSize. null when the table is missing.

---

underlineThickness

readonly underlineThickness: number | null

Defined in: core/src/measure/FontEngine.ts:60

---

unitsPerEm

readonly unitsPerEm: number

Defined in: core/src/measure/FontEngine.ts:36

Cached values extracted once after creation

---

useTypoMetrics

readonly useTypoMetrics: boolean | null

Defined in: core/src/measure/FontEngine.ts:52

OS/2 fsSelection bit 7 — the font's own declaration that renderers should use its typo metrics (not win/hhea) for line spacing. null when the font has no OS/2 table. See FontTypes.ts FontMetrics.useTypoMetrics for why this matters (it's why Unifont, the one oracle font with this bit set, doesn't fit the same office-mode baseline-ratio formula as the rest).
