Crate media_kit 

Full image pipeline — sniff, meta, resize, encode, composite, variants with bomb-guard, EXIF auto-orientation, parallel variant fan-out and async support.

This crate is std-only (the image decoder stack requires std).

Example

use media_kit::pipeline::Pipeline;
use media_kit::resize::{Fit, Filter};
use media_kit::encode::OutFormat;

let jpeg = media_kit::testutil::tiny_jpeg();
let out = Pipeline::new(OutFormat::WebP(None))
    .resize(Fit::MaxSide(200), Filter::Lanczos3)
    .run(&jpeg)?;
assert!(!out.is_empty());

Variants (decode once, fan out in parallel)

use media_kit::variants::{Variant, VariantSet};
use media_kit::resize::Fit;
use media_kit::encode::OutFormat;

let set = VariantSet::new()
    .with(Variant::new("thumb", Fit::MaxSide(200), OutFormat::WebP(None)))
    .with(Variant::new("medium", Fit::Width(800), OutFormat::Jpeg(85)));
// sniffs, bomb-guards, decodes once, auto-orients, fans out
let outs = set.generate_from_bytes(&media_kit::testutil::tiny_jpeg())?;
assert_eq!(outs.len(), 2);

Re-exports

pub use error::MediaError;

Modules

composite

Layering, watermarks, and alpha flattening.

encode

Output encoding for supported formats.

error

Error type for the whole pipeline.

exif

EXIF metadata extraction and orientation handling (behind the exif feature).

meta

Header-only metadata inspection and decompression-bomb guards.

pipeline

High-level decode -> transform -> encode pipeline with bomb-guarding.

resize

Aspect-preserving and cover-fit resizing.

sniff

Magic-byte format sniffing — zero dependencies, no decoding.

testutil

Sample media used by doctests, integration tests, and benches. Shared sample media for doctests, unit tests, and benches.

variants

Multi-size output generation (“thumb”, “medium”, “large”, …).
