pub struct Font(/* private fields */);
Expand description
A sized font face.
A sized font can be requested from a FontFace
.
This type is a shared reference to the loaded font data, cloning it is cheap.
Implementations§
source§impl Font
impl Font
sourcepub fn space_index(&self) -> GlyphIndex
pub fn space_index(&self) -> GlyphIndex
Glyph index for the space ' '
character.
sourcepub fn space_x_advance(&self) -> Px
pub fn space_x_advance(&self) -> Px
Returns the horizontal advance of the space ' '
character.
sourcepub fn shape_text(
self: &Font,
text: &SegmentedText,
config: &TextShapingArgs,
) -> ShapedText
pub fn shape_text( self: &Font, text: &SegmentedText, config: &TextShapingArgs, ) -> ShapedText
Calculates a ShapedText
.
sourcepub fn outline(
&self,
glyph_id: GlyphIndex,
sink: &mut impl OutlineSink,
) -> Option<PxRect>
pub fn outline( &self, glyph_id: GlyphIndex, sink: &mut impl OutlineSink, ) -> Option<PxRect>
Sends the sized vector path for a glyph to sink
.
Returns the glyph bounds if a full outline was sent to the sink.
sourcepub fn h_line_hits(
&self,
glyph_id: GlyphIndex,
line_y_range: (f32, f32),
) -> Option<(f32, f32)>
pub fn h_line_hits( &self, glyph_id: GlyphIndex, line_y_range: (f32, f32), ) -> Option<(f32, f32)>
Ray cast an horizontal line across the glyph and returns the entry and exit hits.
The line_y_range
are two vertical offsets relative to the baseline, the offsets define
the start and inclusive end of the horizontal line, that is, (underline, underline + thickness)
, note
that positions under the baseline are negative so a 2px underline set 1px under the baseline becomes (-1.0, -3.0)
.
Returns Ok(Some(x_enter, x_exit))
where the two values are x-advances, returns None
if there is no hit.
The first x-advance is from the left typographic border to the first hit on the outline,
the second x-advance is from the first across the outline to the exit hit.

impl Font
sourcepub fn variations(&self) -> &RFontVariations
pub fn variations(&self) -> &RFontVariations
Custom font variations.
sourcepub fn metrics(&self) -> &FontMetrics
pub fn metrics(&self) -> &FontMetrics
Sized font metrics.
sourcepub fn ligature_caret_offsets(
&self,
lig: GlyphIndex,
) -> impl ExactSizeIterator<Item = f32> + DoubleEndedIterator + '_
pub fn ligature_caret_offsets( &self, lig: GlyphIndex, ) -> impl ExactSizeIterator<Item = f32> + DoubleEndedIterator + '_
Iterate over pixel offsets relative to lig
glyph start that represents the
caret offset for each cluster that is covered by the ligature, after the first.
The caret offset for the first cluster is the glyph offset and is not yielded in the iterator. The yielded offsets are relative to the glyph position.
