FaceInfo

sealed

Font face metrics from OpenType/TrueType tables. All metric values are in font design units unless noted otherwise.

public int faceIndex

Index of this face within a font collection (TTC).

public string familyName

Font family name from the name table.

public string styleName

Font style name (Regular, Bold, Italic, etc.).

public int weightClass

CSS font-weight value from OS/2 usWeightClass (100-900). 0 if unavailable.

public bool isItalic

Whether this font face is italic (from FreeType style_flags).

public int unitsPerEm

Font design units per em (typically 1000 for CFF, 2048 for TrueType).

public int lineHeight

Distance between consecutive baselines, from the metric pair FreeType selects: typo when the font sets USE_TYPO_METRICS (useTypoMetrics), otherwise hhea.

public int ascentLine

Baseline to top of the tallest glyph, positive. Typo ascender when the font sets USE_TYPO_METRICS, otherwise hhea ascender.

public int capLine

Top of capital letters (OS/2 sCapHeight).

public int meanLine

Top of lowercase letters, x-height (OS/2 sxHeight).

public int descentLine

Baseline to bottom of the lowest glyph, negative. Typo descender when the font sets USE_TYPO_METRICS, otherwise hhea descender.

public int typoAscent

Typographic ascent (OS/2 sTypoAscender): the designer's intended content-box top, tighter than ascentLine for fonts that pad hhea. 0 when the font has no OS/2 table.

public int typoDescent

Typographic descent (OS/2 sTypoDescender), negative below baseline. 0 when unavailable.

public int typoLineGap

Typographic line gap (OS/2 sTypoLineGap): leading the designer suggests between lines.

public int winAscent

Windows clip-box ascent (OS/2 usWinAscent), positive: the extent Windows GDI/DirectWrite will not clip. 0 when unavailable.

public int winDescent

Windows clip-box descent (OS/2 usWinDescent), stored negative below baseline. 0 when unavailable.

public bool useTypoMetrics

Font sets OS/2 USE_TYPO_METRICS (fsSelection bit 7): consumers should prefer the typo metrics for line layout.

public int superscriptOffset

Vertical offset for superscript glyphs (OS/2 ySuperscriptYOffset).

public int superscriptSize

Suggested point size for superscript glyphs (OS/2 ySuperscriptYSize).

public int subscriptOffset

Vertical offset for subscript glyphs (OS/2 ySubscriptYOffset).

public int subscriptSize

Suggested point size for subscript glyphs (OS/2 ySubscriptYSize).

public int underlineOffset

Vertical position of the underline relative to baseline (post table).

public int underlineThickness

Thickness of the underline stroke (post table).

public int strikethroughOffset
