Add the new CLI flags (--threshold, --adaptive, --adaptive-window,
--adaptive-t, --keep-thin) to the options block and "New in 1.0"; note that
--optimize is encoding-only (precision is --path-precision) and that speckle/
thin filtering run after clustering. Add adaptive-threshold examples for CLI,
Python, and Node.
Add package badges, a Packages overview table, and note the npm
build's supported input formats (PNG/JPEG/GIF/BMP/WebP).

Publish under the @visioncortex npm org. Add publishConfig.access=public for
the scoped package and update the install/require examples in both READMEs.
New nodejs/ package: a wasm-bindgen crate (vtracer-wasm) built with wasm-pack
that wraps the vtracer framework, plus a thin JS layer for file I/O. Image
decoding (png/jpeg/gif/bmp via the image crate) runs in wasm too, so the
package has zero native dependencies — no sharp, no node-gyp.
No separate general-purpose wasm crate: the Node package directly owns and
wraps the wasm. Excluded from the cargo workspace (wasm-bindgen cdylib), built
with wasm-pack.
JS API (camelCase options): convertBuffer, convertPixels, convertFile,
convertFileSync — each taking an Options object (preset, colorMode,
hierarchical/cutout mosaic, mode, palette, maxColors, optimize, ...). Ships
index.d.ts types and a node smoke test. README updated.
Verified: builds to wasm32-unknown-unknown; `node test.js` passes; output
matches the CLI/Python bindings (253 paths on the tank sample).
New crates/vtracer-py (pyo3 + maturin, abi3) wrapping the vtracer framework.
Rather than a thin CLI-style wrapper, it exposes a mutable `Config` class with
named properties and `bw`/`poster`/`photo` preset constructors, plus three
input paths — `convert_file`, `convert_bytes` (encoded image, optional format),
and `convert_pixels` (raw RGBA8) — available as `Config` methods and
module-level functions. Palette is a list of `#rrggbb` strings; bad inputs
raise ValueError.
The core crate stays pure: image decoding lives here. The crate is excluded
from the cargo workspace (pyo3 extension-module cdylibs don't link libpython,
which breaks `cargo test` at the root) and is built with maturin. Ships a
vtracer.pyi type stub. README updated.
Replace the 0.6.x help block with the current options (kebab-case flags,
positional input/output, filter-speckle 0..=128), document the new
capabilities (positional args, seam-free mosaic cutout, fixed palette /
auto-quantize, output optimization levels), and refresh the usage examples.
