Struct TextureAtlasPacker 

pub struct TextureAtlasPacker { /* private fields */ }

Simplified packer API that wraps TextureAtlas.

Accepts a batch of (width, height) sprites and returns their allocated (x, y, w, h) rectangles in the same order.

Example

use oximedia_gpu::texture_atlas::TextureAtlasPacker;

let mut packer = TextureAtlasPacker::new(512, 512);
let rects = packer.pack(&[(64, 64), (32, 32)]);
assert_eq!(rects.len(), 2);

Implementations

impl TextureAtlasPacker

pub fn new(max_w: u32, max_h: u32) -> Self

Create a packer backed by an atlas of max_w × max_h texels.

pub fn pack(&mut self, sprites: &[(u32, u32)]) -> Vec<(u32, u32, u32, u32)>

Pack a slice of (width, height) sprites.

Returns a Vec of (x, y, w, h) tuples in the same order as the input. Sprites that do not fit are represented by (0, 0, 0, 0).

pub fn len(&self) -> usize

Total number of sprites currently packed.

pub fn is_empty(&self) -> bool

true if no sprites have been packed.

pub fn utilisation(&self) -> f32

Current utilisation fraction [0, 1].

pub fn clear(&mut self)

Reset the packer, discarding all packed sprites.
