ParsedTtf

Defined in: src/core/font/ttf-parser.ts:41

A parsed TrueType / OpenType font (ISO/IEC 14496-22): metrics, the cmap-derived codepoint→glyph mapping, OpenType layout maps (ligatures, kerning, Arabic joining) and the raw bytes for embedding. Glyph outlines (glyf/CFF) are not decoded — the whole font is embedded in the PDF /FontFile2.

Properties

---

descender

readonly descender: number

---

flags

readonly flags: number

---

fontBBox

readonly fontBBox: readonly [number, number, number, number]

Defined in: src/core/font/ttf-parser.ts:47

---

glyphForCodepoint

readonly glyphForCodepoint: (cp) => number

Defined in: src/core/font/ttf-parser.ts:78

Parameters

cp

number

Returns

number

---

glyphOffsets

readonly glyphOffsets: readonly number[]

Defined in: src/core/font/ttf-parser.ts:76

---

indexToLocFormat

readonly indexToLocFormat: 0 | 1

Defined in: src/core/font/ttf-parser.ts:75

---

italicAngle

readonly italicAngle: number

Defined in: src/core/font/ttf-parser.ts:71

---

joiningForms

readonly joiningForms: ArabicJoiningForms

Defined in: src/core/font/ttf-parser.ts:87

Arabic cursive-joining substitutions (init/medi/fina). Empty for non-Arabic fonts, so the shaper leaves output unchanged.

---

kerning

readonly kerning: KerningMap

Defined in: src/core/font/ttf-parser.ts:82

OpenType pair kerning: "gid1,gid2" → advance adjustment in font units.

---

ligatures

readonly ligatures: LigatureMap

Defined in: src/core/font/ttf-parser.ts:80

OpenType ligature substitutions: input GID sequence "gid1,gid2[,gid3…]" → output GID.

---

lineGap

readonly lineGap: number

Defined in: src/core/font/ttf-parser.ts:54

hhea line gap (font units); with ascender/descender it forms the hhea vertical triple that drives the 'libreoffice' line-height profile (E-PARITY).

---

numGlyphs

readonly numGlyphs: number

Defined in: src/core/font/ttf-parser.ts:74

---

postScriptName

readonly postScriptName: string

Defined in: src/core/font/ttf-parser.ts:45

---

raw

readonly raw: Uint8Array

Defined in: src/core/font/ttf-parser.ts:42

---

sfntVersion

readonly sfntVersion: number

Defined in: src/core/font/ttf-parser.ts:43

---

stemV

readonly stemV: number

Defined in: src/core/font/ttf-parser.ts:72

---

tables

readonly tables: ReadonlyMap<string, TtfTableInfo>

Defined in: src/core/font/ttf-parser.ts:44

---

unitsPerEm

readonly unitsPerEm: number

Defined in: src/core/font/ttf-parser.ts:46

---

vmetrics

readonly vmetrics: object

Defined in: src/core/font/ttf-parser.ts:63

E-PARITY line-height metrics: OS/2 win/typo verticals (font units) selected by layout profile. 'word' uses winAscent/winDescent (the GDI cell box); 'libreoffice' uses the hhea triple above, or typo* when useTypoMetrics is set. All fall back to hhea when the font has no OS/2 table.

typoAscent

readonly typoAscent: number

typoDescent

readonly typoDescent: number

typoLineGap

readonly typoLineGap: number

useTypoMetrics

readonly useTypoMetrics: boolean

winAscent

readonly winAscent: number

winDescent

readonly winDescent: number

---

xHeight

readonly xHeight: number
