Struct RuntimeAtlas 

pub struct RuntimeAtlas { /* private fields */ }

Runtime atlas with pixel data management.

This extends AtlasSession by managing actual pixel data in addition to geometry. Useful for game engines that need to dynamically update GPU textures.

Implementations

impl RuntimeAtlas

pub fn new(cfg: PackerConfig, strategy: RuntimeStrategy) -> Self

Create a new runtime atlas with pixel data management.

pub fn with_background_color(self, color: Rgba<u8>) -> Self

Set the background color for new pages.

pub fn append_with_image( &mut self, key: String, image: &RgbaImage, ) -> Result<(usize, Frame<String>, UpdateRegion)>

Append a texture with its pixel data. Returns (page_id, frame, update_region).

pub fn append( &mut self, key: String, w: u32, h: u32, ) -> Result<(usize, Frame<String>)>

Append a texture by dimensions only (no pixel data). Returns (page_id, frame).

pub fn evict_with_clear( &mut self, page_id: usize, key: &str, clear: bool, ) -> Option<UpdateRegion>

Evict a texture and optionally clear its region. Returns the region that was cleared (if clear=true).

pub fn evict_by_key_with_clear( &mut self, key: &str, clear: bool, ) -> Option<UpdateRegion>

Evict a texture by key and optionally clear its region.

pub fn get_page_image(&self, page_id: usize) -> Option<&RgbaImage>

Get a reference to the pixel data of a page.

pub fn get_page_image_mut(&mut self, page_id: usize) -> Option<&mut RgbaImage>

Get a mutable reference to the pixel data of a page.

pub fn num_pages(&self) -> usize

Get the number of pages with pixel data.

pub fn get_frame(&self, key: &str) -> Option<(usize, &Frame<String>)>

pub fn contains(&self, key: &str) -> bool

pub fn keys(&self) -> Vec<&str>

pub fn texture_count(&self) -> usize

pub fn stats(&self) -> RuntimeStats

pub fn snapshot_atlas(&self) -> Atlas<String>
