Struct TextureAtlas 

pub struct TextureAtlas { /* private fields */ }

Texture atlas with dynamic rectangle packing.

Implementations

impl TextureAtlas

pub fn new( context: Arc<GraphicsContext>, size: u32, format: TextureFormat, ) -> Self

Create a new texture atlas.

Arguments

• context - Graphics context
• size - Size of the atlas texture (must be power of 2)
• format - Texture format

pub fn insert( &mut self, key: AtlasKey, image_data: &[u8], width: u32, height: u32, ) -> Option<AtlasEntry>

Insert an image into the atlas.

Returns the atlas entry if the image was successfully inserted. Returns None if there’s no space in the atlas.

Arguments

• key - Unique key for this image
• image_data - Raw pixel data (must match atlas format)
• size - Size of the image in pixels

pub fn get(&self, key: &AtlasKey) -> Option<&AtlasEntry>

Get an atlas entry by key.

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

Check if the atlas contains a key.

pub fn upload(&mut self)

Upload all pending data to the GPU.

pub fn texture_view(&self) -> &TextureView

Get the texture view for binding.

pub fn texture(&self) -> &Texture

Get the texture for advanced use cases.

pub fn size(&self) -> u32

Get the size of the atlas.

pub fn format(&self) -> TextureFormat

Get the texture format.

pub fn len(&self) -> usize

Get the number of entries in the atlas.

pub fn is_empty(&self) -> bool

Check if the atlas is empty.

pub fn clear(&mut self)

Clear all entries from the atlas.
