Struct TextureImage 

pub struct TextureImage {
    pub format: TextureFormat,
    pub mips: Vec<TextureMip>,
}

A decoded 2D texture: its GPU format plus one or more mip levels, level 0 first. The backend uploads mips directly for compressed formats and generates the minification chain from mips[0] for RGBA8.

Fields

format: TextureFormat

GPU pixel format of every mip.

mips: Vec<TextureMip>

Mip levels, level 0 first.

Implementations

impl TextureImage

pub fn rgba8(width: u32, height: u32, pixels: Vec<u8>) -> Self

Wrap a single RGBA8 level (the PNG / JPEG / procedural path). The upload path generates the mip chain.

pub fn width(&self) -> u32

Base (level 0) dimensions.

pub fn height(&self) -> u32

Base (level 0) height in pixels.

pub fn byte_len(&self) -> usize

Total resident bytes across every mip level (streaming budget accounting).

pub fn into_rgba8(self) -> Result<(u32, u32, Vec<u8>), String>

Recover the base RGBA8 pixels, or an error if the image is block compressed. Used by the sprite / glyph-atlas paths, which upload RGBA8 only.
