@amigo-labs/pincel-wasm

WebAssembly bindings for the Pincel core: the pixel-art document model, tools, command / undo stack and compositor, compiled from Rust with wasm-bindgen and packaged by wasm-pack (--target web).

This is the low-level layer. It hands out a Document and an RGBA frame buffer; drawing the frame, the canvas and every piece of UI is the caller's job. For a mountable editor, use @amigo-labs/pincel instead.

Install

npm install @amigo-labs/pincel-wasm

Usage

import init, { Document } from '@amigo-labs/pincel-wasm';

await init();

const doc = new Document(64, 64);          // or Document.openAseprite(bytes)
doc.applyTool('pencil', x, y, 0xff0000ff); // tool id, position, RGBA
const frame = doc.compose(0, 1);           // frame index, zoom
// frame.pixels is a fresh Uint8Array copy (RGBA8, row-major) on each read

const bytes = doc.saveAseprite();

The document state lives in Rust and is never serialized into JS. Pull changes with doc.drainEvents(), and release the handle with doc.free() when you are done.

Status

Phase 1. The API surface is documented in docs/specs/pincel.md §17.5 of the repository and kept small and stable; open work there is tracked as feature specs indexed in docs/specs/README.md.
