Struct rusttype::ScaledGlyph
[−]
[src]
pub struct ScaledGlyph<'a> { /* fields omitted */ }
A glyph augmented with scaling information. You can query such a glyph for information that depends on the scale of the glyph.
Methods
impl<'a> ScaledGlyph<'a>
[src]
pub fn id(&self) -> GlyphId
[src]
The glyph identifier for this glyph.
pub fn font(&self) -> Option<&Font<'a>>
[src]
The font to which this glyph belongs. If the glyph is a standalone glyph
that owns its resources, it no longer has a reference to the font which
it was created from (using standalone()
). In which case, None
is
returned.
pub fn into_unscaled(self) -> Glyph<'a>
[src]
A reference to this glyph without the scaling
pub fn unscaled(&self) -> &Glyph<'a>
[src]
Removes the scaling from this glyph
pub fn positioned(self, p: Point<f32>) -> PositionedGlyph<'a>
[src]
Augments this glyph with positioning information, making methods that depend on the position of the glyph available.
pub fn scale(&self) -> Scale
[src]
pub fn h_metrics(&self) -> HMetrics
[src]
Retrieves the "horizontal metrics" of this glyph. See HMetrics
for
more detail.
pub fn shape(&self) -> Option<Vec<Contour>>
[src]
Produces a list of the contours that make up the shape of this glyph.
Each contour consists of a sequence of segments. Each segment is either
a straight Line
or a Curve
.
The winding of the produced contours is clockwise for closed shapes, anticlockwise for holes.
pub fn exact_bounding_box(&self) -> Option<Rect<f32>>
[src]
The bounding box of the shape of this glyph, not to be confused with
pixel_bounding_box
, the conservative pixel-boundary bounding box. The
coordinates are relative to the glyph's origin.
pub fn standalone(&self) -> ScaledGlyph<'static>
[src]
Constructs a glyph that owns its data from this glyph. This is similar
to Glyph::standalone
. See that function for more details.
