Expand description

Contains font data in an atlas, where each character occupied a small rectangle.

More characters can be added, possibly expanding the texture.

Fields§

§image: FontImage§dirty: Rectu

What part of the image that is dirty

§cursor: (usize, usize)

Used for when allocating new rectangles.

§row_height: usize§overflowed: bool

Set when someone requested more space than was available.

§discs: Vec<PrerasterizedDisc>

pre-rasterized discs of radii 2^i, where i is the index.

Implementations§

source§

impl TextureAtlas

source

pub fn new(size: [usize; 2]) -> Self

source

pub fn size(&self) -> [usize; 2]

source

pub fn prepared_discs(&self) -> Vec<PreparedDisc>

Returns the locations and sizes of pre-rasterized discs (filled circles) in this atlas.

source

fn max_height(&self) -> usize

source

pub fn fill_ratio(&self) -> f32

When this get high, it might be time to clear and start over!

source

pub fn take_delta(&mut self) -> Option<ImageDelta>

Call to get the change to the image since last call.

source

pub fn allocate( &mut self, (w, h): (usize, usize) ) -> ((usize, usize), &mut FontImage)

Returns the coordinates of where the rect ended up, and invalidates the region.
