Struct fontdue::FontSettings

pub struct FontSettings {
    pub collection_index: u32,
    pub scale: f32,
    pub load_substitutions: bool,
}

Settings for controlling specific font and layout behavior.

Fields

collection_index: u32

The default is 0. The index of the font to use if parsing a font collection.

scale: f32

The default is 40. The scale in px the font geometry is optimized for. Fonts rendered at the scale defined here will be the most optimal in terms of looks and performance. Glyphs rendered smaller than this scale will look the same but perform slightly worse, while glyphs rendered larger than this will looks worse but perform slightly better. The units of the scale are pixels per Em unit.

load_substitutions: bool

The default is true. If enabled, will load glyphs for substitutions (liagtures, etc.) from the gsub table on compatible fonrs. Only makes a difference when using indexed operations, i.e. Font::raserize_indexed, as singular characters do not have enough context to be substituted.

Trait Implementations

impl Clone for FontSettings

fn clone(&self) -> FontSettings

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for FontSettings

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl Default for FontSettings

fn default() -> FontSettings

Returns the “default value” for a type.

impl PartialEq for FontSettings

fn eq(&self, other: &FontSettings) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
