Struct skrifa::OutlineGlyph

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

A scalable glyph outline.

This can be sourced from the glyf, CFF or CFF2 tables. Use the format method to determine which was chosen for this glyph.

Implementations

impl<'a> OutlineGlyph<'a>

pub fn format(&self) -> OutlineGlyphFormat

Returns the underlying source format for this outline.

pub fn glyph_id(&self) -> GlyphId

Returns the glyph identifier for this outline.

pub fn has_overlaps(&self) -> Option<bool>

Returns a value indicating if the outline may contain overlapping contours or components.

For CFF outlines, returns None since this information is unavailable.

pub fn has_hinting(&self) -> Option<bool>

Returns a value indicating whether the outline has hinting instructions.

For CFF outlines, returns None since this is unknown prior to loading the outline.

pub fn draw_memory_size(&self, hinting: Hinting) -> usize

Returns the size (in bytes) of the temporary memory required to draw this outline.

This is used to compute the size of the memory buffer required for the DrawSettings::with_memory method.

The hinting parameter determines which hinting method, if any, will be used for drawing which has an effect on memory requirements.

The appropriate hinting types are as follows:

For draw settings	Use hinting
DrawSettings::unhinted	Hinting::None
DrawSettings::hinted	Hinting::Embedded

pub fn draw<'s>( &self, settings: impl Into<DrawSettings<'a>>, pen: &mut impl OutlinePen, ) -> Result<AdjustedMetrics, DrawError>

Draws the outline glyph with the given settings and emits the resulting path commands to the specified pen.

Trait Implementations

impl<'a> Clone for OutlineGlyph<'a>

fn clone(&self) -> OutlineGlyph<'a>

Returns a copy of the value.

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

Performs copy-assignment from source.
