Struct FontConfig 

pub struct FontConfig { /* private fields */ }

Handle obtained after Fontconfig has been initialised.

Implementations

impl FontConfig

pub fn substitute(&mut self, pat: &mut Pattern, kind: MatchKind)

Create a configuration Set configuration as default.

Sets the current default configuration to config. Implicitly calls FcConfigBuildFonts if necessary, and FcConfigReference() to inrease the reference count in config since 2.12.0, returning FcFalse if that call fails. Execute substitutions

Calls FcConfigSubstituteWithPat setting p_pat to NULL. Returns false if the substitution cannot be performed (due to allocation failure). Otherwise returns true.

pub fn fontset_match( &mut self, sets: &mut [FontSet<'_>], pat: &mut Pattern, ) -> OwnedPattern

Return the best font from a set of font sets

Finds the font in sets most closely matching pattern and returns the result of FcFontRenderPrepare for that font and the provided pattern. This function should be called only after FcConfigSubstitute and FcDefaultSubstitute have been called for pattern; otherwise the results will not be correct. If config is NULL, the current configuration is used. Returns NULL if an error occurs during this process.

pub fn find(&mut self, family: String, style: Option<String>) -> Option<Font>

Find a font of the given family (e.g. Dejavu Sans, FreeSerif), optionally filtering by style. Both fields are case-insensitive.
