Struct rusttype::Glyph
[−]
[src]
pub struct Glyph<'a> { /* fields omitted */ }
A single glyph of a font. this may either be a thin wrapper referring to the font and the glyph id, or it may be a standalone glyph that owns the data needed by it.
A Glyph
does not have an inherent scale or position associated with it. To augment a glyph with a
size, give it a scale using scaled
. You can then position it using positioned
.
Methods
impl<'a> Glyph<'a>
[src]
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 id(&self) -> GlyphId
[src]
The glyph identifier for this glyph.
pub fn scaled(self, scale: Scale) -> ScaledGlyph<'a>
[src]
Augments this glyph with scaling information, making methods that depend on the scale of the glyph available.
pub fn standalone(&self) -> Glyph<'static>
[src]
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()
.
pub fn get_data(&self) -> Option<Arc<SharedGlyphData>>
[src]
Get the data from this glyph (such as width, extents, vertices, etc.). Only possible if the glyph is a shared glyph.
