Struct epaint::TextureAtlas

pub struct TextureAtlas { /* private fields */ }

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

More characters can be added, possibly expanding the texture.

Implementations

impl TextureAtlas

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

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

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

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

pub fn fill_ratio(&self) -> f32

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

pub fn texture_options() -> TextureOptions

The texture options suitable for a font texture

pub fn image(&self) -> &FontImage

The full font atlas image.

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

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

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.

Trait Implementations

impl Clone for TextureAtlas

fn clone(&self) -> TextureAtlas

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.
