Implementations

impl SwashCache

pub fn new() -> Self

Create a new swash cache

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

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

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

Create a swash Image from a cache key, caching results

pub fn with_pixels<F: FnMut(i32, i32, u32)>(
    &mut self,
    matches: &FontMatches<'_>,
    cache_key: CacheKey,
    base: u32,
    f: F
)

Enumerate pixels in an Image, use with_image for better performance
