Struct glium_glyph::GlyphBrush

pub struct GlyphBrush<'font, 'a, H: BuildHasher = DefaultSectionHasher> { /* fields omitted */ }

Methods

impl<'font, 'p> GlyphBrush<'font, 'p>

pub fn new<'a: 'font, F: Facade, V: Into<Vec<Font<'a>>>>(
    facade: &F,
    fonts: V
) -> Self

impl<'font, 'p, H: BuildHasher> GlyphBrush<'font, 'p, H>

pub fn queue_custom_layout<'a, S, G>(&mut self, section: S, custom_layout: &G) where
    G: GlyphPositioner,
    S: Into<Cow<'a, VariedSection<'a>>>, 

Queues a section/layout to be drawn by the next call of draw_queued. Can be called multiple times to queue multiple sections for drawing.

Used to provide custom GlyphPositioner logic, if using built-in Layout simply use queue

Benefits from caching, see caching behaviour.

pub fn queue<'a, S>(&mut self, section: S) where
    S: Into<Cow<'a, VariedSection<'a>>>, 

Queues a section/layout to be drawn by the next call of draw_queued. Can be called multiple times to queue multiple sections for drawing.

Benefits from caching, see caching behaviour.

pub fn draw_queued<F: Facade + Deref<Target = Context>>(
    &mut self,
    facade: &F,
    frame: &mut Frame
)

pub fn draw_queued_with_transform<F: Facade + Deref<Target = Context>>(
    &mut self,
    transform: [[f32; 4]; 4],
    facade: &F,
    frame: &mut Frame
)

pub fn add_font_bytes<'a: 'font, B: Into<SharedBytes<'a>>>(
    &mut self,
    font_data: B
) -> FontId

pub fn add_font<'a: 'font>(&mut self, font_data: Font<'a>) -> FontId

Adds an additional font to the one(s) initially added on build.

Returns a new FontId to reference this font.

Trait Implementations

impl<'font, 'l, H: BuildHasher> GlyphCruncher<'font> for GlyphBrush<'font, 'l, H>

fn pixel_bounds_custom_layout<'a, S, L>(
    &mut self,
    section: S,
    custom_layout: &L
) -> Option<Rect<i32>> where
    L: GlyphPositioner + Hash,
    S: Into<Cow<'a, VariedSection<'a>>>, 

Returns the pixel bounding box for the input section using a custom layout. The box is a conservative whole number pixel rectangle that can contain the section.

fn glyphs_custom_layout<'a, 'b, S, L>(
    &'b mut self,
    section: S,
    custom_layout: &L
) -> PositionedGlyphIter<'b, 'font> where
    L: GlyphPositioner + Hash,
    S: Into<Cow<'a, VariedSection<'a>>>, 

Returns an iterator over the PositionedGlyphs of the given section with a custom layout.

fn fonts(&self) -> &[Font<'font>]

Returns the available fonts.

The FontId corresponds to the index of the font data.

default fn pixel_bounds<'a, S>(&mut self, section: S) -> Option<Rect<i32>> where
    S: Into<Cow<'a, VariedSection<'a>>>, 

Returns the pixel bounding box for the input section. The box is a conservative whole number pixel rectangle that can contain the section.

default fn glyphs<'a, S>(
    &'b mut self,
    section: S
) -> Map<Iter<'b, (PositionedGlyph<'font>, [f32; 4], FontId)>, fn(&'b (PositionedGlyph<'font>, [f32; 4], FontId)) -> &'b PositionedGlyph<'font>> where
    S: Into<Cow<'a, VariedSection<'a>>>, 

Returns an iterator over the PositionedGlyphs of the given section.
