Implementations

impl<'a> SwashCache<'a>

pub fn new(font_system: &'a FontSystem) -> Self

Create a new swash cache

pub fn get_image_uncached(&mut self, cache_key: CacheKey) -> Option<SwashImage>

Create a swash Image from a cache key, without caching results

pub fn get_image(&mut self, cache_key: CacheKey) -> &Option<SwashImage>

Create a swash Image from a cache key, caching results

pub fn with_pixels<F: FnMut(i32, i32, Color)>(
    &mut self,
    cache_key: CacheKey,
    base: Color,
    f: F
)

Enumerate pixels in an Image, use with_image for better performance
