Struct rusttype::SizedGlyph

pub struct SizedGlyph<'a> {
    // some 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> SizedGlyph<'a>

fn positioned(self, p: Point<f32>) -> PositionedGlyph<'a>

Augments this glyph with positioning information, making methods that depend on the position of the glyph available.

fn h_metrics(&self) -> HMetrics

Retrieves the "horizontal metrics" of this glyph. See HMetrics for more detail.

fn shape(&self) -> Option<Vec<Contour>>

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.

fn exact_bounding_box(&self) -> Option<Rect<f32>>

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.

fn standalone(&self) -> SizedGlyph<'static>

Constructs a glyph that owns its data from this glyph. This is similar to Glyph::standalone. See that function for more details.

Methods from Deref<Target=Glyph<'a>>

fn font(&self) -> Option<&Font<'a>>

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.

fn id(&self) -> GlyphId

The glyph identifier for this glyph.

fn scaled<S: Into<Scale>>(self, scale: S) -> SizedGlyph<'a>

Augments this glyph with scaling information, making methods that depend on the scale of the glyph available.

fn standalone(&self) -> Glyph<'static>

Turns a Glyph<'a> into a Glyph<'static>. This produces a glyph that owns its resources, extracted from the font. This glyph can outlive the font that it comes from.

Calling standalone() on a standalone glyph shares the resources, and is equivalent to clone().

Trait Implementations
