Struct epaint::TextureAtlas
source · pub struct TextureAtlas {
image: FontImage,
dirty: Rectu,
cursor: (usize, usize),
row_height: usize,
overflowed: bool,
discs: Vec<PrerasterizedDisc>,
}
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
impl TextureAtlas
pub fn new(size: [usize; 2]) -> Self
pub fn size(&self) -> [usize; 2]
sourcepub fn prepared_discs(&self) -> Vec<PreparedDisc>
pub fn prepared_discs(&self) -> Vec<PreparedDisc>
Returns the locations and sizes of pre-rasterized discs (filled circles) in this atlas.
fn max_height(&self) -> usize
sourcepub fn fill_ratio(&self) -> f32
pub fn fill_ratio(&self) -> f32
When this get high, it might be time to clear and start over!
sourcepub fn texture_options() -> TextureOptions
pub fn texture_options() -> TextureOptions
The texture options suitable for a font texture
sourcepub fn take_delta(&mut self) -> Option<ImageDelta>
pub fn take_delta(&mut self) -> Option<ImageDelta>
Call to get the change to the image since last call.
