pub struct TextureAtlas { /* private fields */ }

A dynamic texture atlas that manages allocation and GPU updates.

Implementations

impl TextureAtlas

pub fn new( device: &(dyn GraphicsDevice + 'static), size: u32, format: TextureFormat, label: &str, ) -> Result<TextureAtlas, Box<dyn Error + Send + Sync>>

Creates a new texture atlas with the specified size.

pub fn allocate_and_upload( &mut self, device: &(dyn GraphicsDevice + 'static), width: u32, height: u32, pixels: &[u8], bytes_per_pixel: u32, ) -> Option<AtlasRect>

Allocates space for a sub-texture and uploads data to the GPU.

pub fn texture(&self) -> TextureId

Returns the texture handle that stores the atlas pixels.

pub fn view(&self) -> TextureViewId

Returns the texture view used to sample the atlas.

pub fn size(&self) -> u32

Returns the atlas side length in pixels.
