deno-canvas

Canvas API for Deno, ported from canvaskit-wasm (Skia).

Installation

Import from https://deno.land/x/canvas@v1.0.0/mod.ts or just import from raw GitHub URL, https://raw.githubusercontent.com/DjDeveloperr/deno-canvas/master/mod.ts.

Usage

mod.ts provides a default export exposing the complete CanvasKit API, and other exports from the file are types and util functions.

import Canvas, { CanvasRenderingContext2D, dataURLtoFile } from 'https://deno.land/x/canvas@v1.0.0/mod.ts'
import { serve } from "https://deno.land/std@0.78.0/http/server.ts";

const canvas = Canvas.MakeCanvas(200, 200);
const ctx = canvas.getContext('2d') as CanvasRenderingContext2D;

ctx.fillStyle = 'red';
ctx.fillRect(10, 10, 200 - 20, 200 - 20);

const data = dataURLtoFile(canvas.toDataURL());

const server = serve({ hostname: "0.0.0.0", port: 8080 });
console.log(`HTTP webserver running. Access it at: http://localhost:8080/`);

for await (const request of server) {
  request.respond({ status: 200, body: data });
}

And run with deno run --allow-red --allow-read filename.ts! Or you can directly run from URL, https://raw.githubusercontent.com/DjDeveloperr/deno-canvas/master/examples/square.ts
