Properties

HasCffOutlines: Gets a value indicating whether this face uses CFF outlines.

HasKerningPairs: Gets a value indicating whether the face carries legacy kern format-0 pairs: the pair kerning the engine applies to text it shapes from the character map for a document outside compatibility mode 15, and the fallback for one in it. A GPOS kern feature alone does not count here; a face that kerns only there is kerned by the engine only when a ShapeRequest asks for OpenType kerning, as Word kerns it only in mode 15 (WORDQUIRKS.md WQ-0049).

HheaAscender: Gets the ascent from the horizontal header (hhea.ascender, fUnits).

HheaDescender: Gets the descent from the horizontal header (hhea.descender, fUnits; usually negative).

HheaLineGap: Gets the line gap from the horizontal header (hhea.lineGap, fUnits).

IsSymbolEncoded: Gets a value indicating whether this face's character map is symbol-encoded — that is, whether the subtable DocWright maps through is a Microsoft Symbol (3,0) table.

NeedsSyntheticBold: Gets a value indicating whether synthetic bold should be applied.

NeedsSyntheticItalic: Gets a value indicating whether synthetic italic should be applied.

SourceName: Gets the source identifier for this face (file path or embedded part id).

StrikeoutPosition: Gets the strikeout position from OS/2 (yStrikeoutPosition, fUnits): the top edge of the strikethrough above the baseline, which Word scales to the drawn size and rounds to its grain (WQ-0054). Zero when undeclared.

StrikeoutSize: Gets the strikeout thickness from OS/2 (yStrikeoutSize, fUnits). Zero when undeclared, in which case a caller falls back rather than drawing nothing.

SubscriptYOffset: Gets the subscript baseline drop from OS/2 (ySubscriptYOffset, fUnits).

SubscriptYSize: Gets the subscript em size from OS/2 (ySubscriptYSize, fUnits; 0 when undeclared).

SuperscriptYOffset: Gets the superscript baseline rise from OS/2 (ySuperscriptYOffset, fUnits).

SuperscriptYSize: Gets the superscript em size from OS/2 (ySuperscriptYSize, fUnits; 0 when undeclared).

TypoDescender: Gets the descent from OS/2 typo metrics (fUnits; usually negative).

UnderlinePosition: Gets the underline position from the post table (fUnits; negative below the baseline, as the table stores it). Word draws an underline whose top edge is this, scaled to the drawn size and rounded to its 1/600-inch grain, below the baseline (WQ-0054). Zero when the table is absent or too short.

UnderlineThickness: Gets the underline thickness from the post table (fUnits). Word's underline is this, scaled to the drawn size and rounded to its grain (WQ-0054). Zero when undeclared, in which case a caller falls back rather than drawing nothing.

UnitsPerEm: Gets the font's design units per em (from the OpenType head table).

UsesTypoMetrics: Gets a value indicating whether USE_TYPO_METRICS is set in OS/2 fsSelection.

WinDescent: Gets the descent from OS/2 Windows metrics (fUnits; positive magnitude).

GetAdvanceWidthFontUnits(ushort): Gets one glyph advance in font units from hmtx.

GetKerningAdjustmentFontUnits(ushort, ushort): Gets the legacy kern table's adjustment for one glyph pair, in font units: the pair kerning the engine applies to text it shapes from the character map for a document outside compatibility mode 15, never the GPOS kern feature's value.

TryGetGlyphBoundingBox(ushort, out GlyphBoundingBox): Tries to get one glyph bounding box (fUnits) parsed from glyf/loca.
