Struct font_kit::sources::directwrite::DirectWriteSource

source ·
pub struct DirectWriteSource { /* private fields */ }
Expand description

A source that contains the installed fonts on Windows.

Implementations§

source§

impl DirectWriteSource

source

pub fn new() -> DirectWriteSource

Opens the system font collection.

source

pub fn all_fonts(&self) -> Result<Vec<Handle>, SelectionError>

Returns paths of all fonts installed on the system.

source

pub fn all_families(&self) -> Result<Vec<String>, SelectionError>

Returns the names of all families installed on the system.

source

pub fn select_family_by_name( &self, family_name: &str ) -> Result<FamilyHandle, SelectionError>

Looks up a font family by name and returns the handles of all the fonts in that family.

TODO(pcwalton): Case-insensitivity.

source

pub fn select_by_postscript_name( &self, postscript_name: &str ) -> Result<Handle, SelectionError>

Selects a font by PostScript name, which should be a unique identifier.

On the DirectWrite backend, this does a brute-force search of installed fonts to find the one that matches.

source

pub fn select_best_match( &self, family_names: &[FamilyName], properties: &Properties ) -> Result<Handle, SelectionError>

Performs font matching according to the CSS Fonts Level 3 specification and returns the handle.
