Struct HintingInstance

pub struct HintingInstance {
    size: Size,
    coords: Vec<NormalizedCoord>,
    target: Target,
    kind: HinterKind,
}

Hinting instance that uses information embedded in the font to perform grid-fitting.

Fields

size: Size

coords: Vec<NormalizedCoord>

target: Target

kind: HinterKind

Implementations

impl HintingInstance

pub fn new<'a>( outline_glyphs: &OutlineGlyphCollection<'_>, size: Size, location: impl Into<LocationRef<'a>>, options: impl Into<HintingOptions>, ) -> Result<Self, DrawError>

Creates a new embedded hinting instance for the given outline collection, size, location in variation space and hinting mode.

pub fn size(&self) -> Size

Returns the currently configured size.

pub fn location(&self) -> LocationRef<'_>

Returns the currently configured normalized location in variation space.

pub fn target(&self) -> Target

Returns the currently configured hinting target.

pub fn reconfigure<'a>( &mut self, outlines: &OutlineGlyphCollection<'_>, size: Size, location: impl Into<LocationRef<'a>>, options: impl Into<HintingOptions>, ) -> Result<(), DrawError>

Resets the hinter state for a new font instance with the given outline collection and settings.

pub fn is_enabled(&self) -> bool

Returns true if hinting should actually be applied for this instance.

Some TrueType fonts disable hinting dynamically based on the instance configuration.

pub(super) fn draw( &self, glyph: &OutlineGlyph<'_>, memory: Option<&mut [u8]>, path_style: PathStyle, pen: &mut impl OutlinePen, is_pedantic: bool, ) -> Result<AdjustedMetrics, DrawError>

Trait Implementations

impl Clone for HintingInstance

fn clone(&self) -> HintingInstance

Returns a duplicate of the value.

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

Performs copy-assignment from source.

impl<'a> From<&'a HintingInstance> for DrawSettings<'a>

fn from(value: &'a HintingInstance) -> Self

Converts to this type from the input type.
