Struct TextureAtlasSources

pub struct TextureAtlasSources {
    pub texture_ids: HashMap<AssetId<Image>, usize>,
}

Stores a mapping from sub texture handles to the related area index.

Generated by TextureAtlasBuilder.

Fields

texture_ids: HashMap<AssetId<Image>, usize>

Maps from a specific image handle to the index in textures where they can be found.

Implementations

impl TextureAtlasSources

pub fn texture_index(&self, texture: impl Into<AssetId<Image>>) -> Option<usize>

Retrieves the texture section index of the given texture handle.

pub fn handle( &self, layout: Handle<TextureAtlasLayout>, texture: impl Into<AssetId<Image>>, ) -> Option<TextureAtlas>

Creates a TextureAtlas handle for the given texture handle.

pub fn texture_rect( &self, layout: &TextureAtlasLayout, texture: impl Into<AssetId<Image>>, ) -> Option<URect>

Retrieves the texture section rectangle of the given texture handle in pixels.

pub fn uv_rect( &self, layout: &TextureAtlasLayout, texture: impl Into<AssetId<Image>>, ) -> Option<Rect>

Retrieves the texture section rectangle of the given texture handle in UV coordinates. These are within the range [0..1], as a fraction of the entire texture atlas’ size.

Trait Implementations

impl Debug for TextureAtlasSources

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
