Struct radiant_rs::Font

pub struct Font { /* fields omitted */ }

A font used for writing on a Layer.

Use Font::builder() to create a new font from a registered system font or a local file. The Font::from_file() is a shortcut to achieve the latter.

In addition to the usual properties of a font, radiant also assigns a fixed size to each font object. Instead of modifying this value, you can clone a new font with a different size using Font::with_size().

Methods

impl Font

pub fn builder(context: &RenderContext) -> FontBuilder

Returns a font builder for font construction.

Examples

let my_font = Font::builder(&rendercontext).family("Arial").size(16.0).build().unwrap();

pub fn from_file(context: &RenderContext, file: &str) -> Result<Font>

Creates a font instance from a file.

Important traits for Vec<u8>

impl Write for Vec<u8>

pub fn query_all() -> Vec<String>

Returns the names of all available system fonts.

pub fn query() -> FontQueryBuilder

Returns a query builder to retrieve the names of all available system fonts with the given properties (e.g. monospace).

Examples

let monospace_fonts = Font::query().monospace().italic().fetch();

pub fn clone_with_size(&self, size: f32) -> Font

Returns a new font instance with given size.

pub fn write<T>(     &self,     layer: &Layer,     text: &str,     position: T,     color: Color ) -> &Font where     (f32, f32): From<T>,

Write to given layer.

pub fn write_wrapped<T>(     &self,     layer: &Layer,     text: &str,     position: T,     color: Color,     max_width: f32 ) -> &Font where     (f32, f32): From<T>,

Write to given layer. Breaks lines after max_width pixels.

pub fn write_transformed<T, U>(     &self,     layer: &Layer,     text: &str,     position: T,     color: Color,     max_width: f32,     rotation: f32,     scale: U ) -> &Font where     (f32, f32): From<T> + From<U>,

Write to given layer. Breaks lines after max_width pixels and applies given rotation and scaling.

pub fn arc(self) -> Arc<Self>

Returns the font wrapped in an std::Arc.
