Struct nannou::ui::backend::glium::GlyphCache
[−]
[src]
pub struct GlyphCache { /* fields omitted */ }
A rusttype GlyphCache
along with a glium::texture::Texture2d
for caching text on the GPU
.
Methods
impl GlyphCache
[src]
pub fn with_dimensions<F>(
facade: &F,
width: u32,
height: u32
) -> Result<GlyphCache, TextureCreationError> where
F: Facade,
[src]
facade: &F,
width: u32,
height: u32
) -> Result<GlyphCache, TextureCreationError> where
F: Facade,
Construct a GlyphCache with the given texture dimensions.
When calling GlyphCache::new
, the get_framebuffer_dimensions
method is used to produce
the width and height. However, often creating a texture the size of the screen might not be
large enough to cache the necessary text for an application. The following constant
multiplier is used to ensure plenty of room in the cache.
pub fn new<F>(facade: &F) -> Result<GlyphCache, TextureCreationError> where
F: Facade,
[src]
F: Facade,
Construct a GlyphCache
with a size equal to the given Display
's current framebuffer
dimensions.
pub fn texture(&self) -> &Texture2d
[src]
The texture used to cache the glyphs on the GPU.
