Structs

• CachedShapeData 🔒
• Font
• FontBaseline
• FontDescriptor
  FontDescriptor describes the parameters of a Font. It represents rendering a given font template at a particular size, with a particular font-variant-caps applied, etc. This contrasts with FontTemplateDescriptor in that the latter represents only the parameters inherent in the font data (weight, stretch, etc.).
• FontFamilyDescriptor
  The font family parameters for font selection.
• FontGroup
  A FontGroup is a prioritised list of fonts for a given set of font styles. It is used by TextRun to decide which font to render a character with. If none of the fonts listed in the styles are suitable, a fallback font may be used.
• FontGroupFamily 🔒
  A FontGroupFamily is a single font family in a FontGroup. It corresponds to one of the families listed in the font-family CSS property. The corresponding font data is lazy-loaded, only if actually needed. A single FontGroupFamily can have multiple fonts, in the case that individual fonts only cover part of the Unicode range.
• FontGroupFamilyMember 🔒
  A FontGroupFamily can have multiple members if it is a “composite face”, meaning that it is defined by multiple @font-face declarations which vary only by their unicode-range descriptors. In this case, font selection will select a single member that contains the necessary unicode character. Unicode ranges are specified by the FontGroupFamilyMember::template member.
• FontMetrics
• RunMetrics
• ShapeCacheEntry 🔒
  An entry in the shape cache.
• ShapingFlags
• ShapingOptions
  Various options that control text shaping.

Enums

• FontSearchScope
  The scope within which we will look for a font.

Constants

• BASE
• CBDT
• COLR
• GPOS
• GSUB
• KERN
• LAST_RESORT_GLYPH_ADVANCE
• SBIX

Statics

• TEXT_SHAPING_PERFORMANCE_COUNTER 🔒
  Nanoseconds spent shaping text across all layout threads.

Traits

• FontTableMethods
• FontTableTagConversions 🔒
• PlatformFontMethods

Functions

• get_and_reset_text_shaping_performance_counter
  Get the number of nanoseconds spent shaping text across all threads.
• map_platform_values_to_style_values 🔒
  Given a mapping array mapping and a value, map that value onto the value specified by the array. For instance, for FontConfig values of weights, we would map these onto the CSS [0..1000] range by creating an array as below. Values that fall between two mapped values, will be adjusted by the weighted mean.
