pub struct Render<'a> { /* private fields */ }

Builder type for rendering a glyph into an image.

See the module level documentation for detail.

Implementations

impl<'a> Render<'a>

pub fn new(sources: &'a [Source]) -> Self

Creates a new builder for configuring rendering using the specified prioritized list of sources.

pub fn format(&mut self, format: Format) -> &mut Self

Specifies the target format for rasterizing an outline. Default is Format::Alpha.

pub fn style(&mut self, style: impl Into<Style<'a>>) -> &mut Self

Specifies the path style to use when rasterizing an outline. Default is Fill::NonZero.

pub fn offset(&mut self, offset: Vector) -> &mut Self

Specifies an additional offset to apply when rasterizing an outline. Default is (0, 0).

pub fn transform(&mut self, transform: Option<Transform>) -> &mut Self

Specifies a transformation matrix to apply when rasterizing an outline. Default is None.

pub fn embolden(&mut self, strength: f32) -> &mut Self

Specifies the strength of a faux bold transform to apply when rasterizing an outline. Default is 0.

pub fn default_color(&mut self, color: [u8; 4]) -> &mut Self

Specifies an RGBA color to use when rasterizing layers of a color outline that do not directly reference a palette color. Default is [128, 128, 128, 255].

pub fn render_into( &self, scaler: &mut Scaler<'_>, glyph_id: GlyphId, image: &mut Image ) -> bool

Renders the specified glyph using the current configuration into the provided image.

pub fn render( &self, scaler: &mut Scaler<'_>, glyph_id: GlyphId ) -> Option<Image>

Renders the specified glyph using the current configuration.
