Struct ImageAsset 

pub struct ImageAsset {
    pub width: u32,
    pub height: u32,
    pub format: PixelFormat,
    pub data: Vec<u8>,
    pub mip_levels: Vec<Vec<u8>>,
}

A loaded image — raw decoded pixel data.

Mip-maps can be generated by an AssetProcessor after load.

Fields

width: u32

Width in pixels.

height: u32

Height in pixels.

format: PixelFormat

Pixel format.

data: Vec<u8>

Raw pixel bytes, row-major top-to-bottom.

mip_levels: Vec<Vec<u8>>

Mip levels (empty if no mips have been generated).

Implementations

impl ImageAsset

pub fn solid_color(width: u32, height: u32, rgba: [u8; 4]) -> Self

Create a solid-colour image of the given size.

pub fn byte_size(&self) -> usize

Total byte size of the base level.

pub fn channels(&self) -> usize

Number of channels implied by the pixel format.

Trait Implementations

impl AssetLoader<ImageAsset> for RawImageLoader

fn load(&self, bytes: &[u8], path: &AssetPath) -> Result<ImageAsset, String>

Load an asset from the given byte slice.

fn extensions(&self) -> &[&str]

Returns the file extensions this loader handles (without the dot).

impl AssetProcessor<ImageAsset> for MipMapGenerator

fn process( &self, asset: &mut ImageAsset, _path: &AssetPath, ) -> Result<(), String>

Mutate or replace the asset in-place.

fn name(&self) -> &str

Human-readable name used in debug output.

impl Clone for ImageAsset

fn clone(&self) -> ImageAsset

Returns a duplicate of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for ImageAsset

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.
