Struct epaint::TextureAtlas

source · [−]

pub struct TextureAtlas { /* private fields */ }

Expand description

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

More characters can be added, possibly expanding the texture.

Implementations

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.
