Crate smix_annotate 

smix-annotate — screenshot annotation.

Compose circle / arrow / text / box / line primitives onto a PNG, then emit compressed output. RFC: docs/ai-guide/rfc-v0.3.0- annotated-screenshots.md.

Quick tour

use smix_annotate::{Annotator, Annotation, Color, Position, Compression};

let png = std::fs::read("input.png")?;
let out = Annotator::new(&png)?
    .add(Annotation::circle(Position::pixel(100, 100))
        .color(Color::RED)
        .radius(40))
    .compression(Compression::BALANCED)
    .render()?;
std::fs::write("output.png", out)?;

v0.3.0 scope

• 5 primitives: circle, arrow, text, box, line
• Position resolvers: absolute pixel + normalized (0..1) (selector-relative via a11y tree — wire lives in smix-adapter-maestro runtime, not in this crate; caller resolves selector → pixel before adding annotation)
• Named + hex + rgba color palette
• Compression 3 presets: fast, balanced, aggressive
• Text rendering via ab_glyph; font supplied by caller (v0.3.5 will bundle Inter + Noto Sans SC)
