Struct OutlineGlyph

pub struct OutlineGlyph<'a> {
    kind: OutlineKind<'a>,
}

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.

Fields

kind: OutlineKind<'a>

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.

fn draw_unhinted( &self, size: Size, location: impl Into<LocationRef<'a>>, user_memory: Option<&mut [u8]>, path_style: PathStyle, pen: &mut impl OutlinePen, ) -> Result<AdjustedMetrics, DrawError>

fn draw_unscaled( &self, location: impl Into<LocationRef<'a>>, user_memory: Option<&mut [u8]>, sink: &mut impl UnscaledOutlineSink, ) -> Result<i32, DrawError>

Internal drawing API for autohinting that offers unified compact storage for unscaled outlines.

pub(crate) fn font(&self) -> &FontRef<'a>

fn units_per_em(&self) -> u16

Trait Implementations

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

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

Returns a duplicate of the value.

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

Performs copy-assignment from source.
