askey is a SvelteKit-powered app that turns any static or animated image into high-fidelity ASCII art. Upload GIFs, APNGs, PNGs, or JPEGs, tweak pro-level tone controls, and export the result to TXT, SVG, PNG, WebP, GIF, APNG, or JSON for the askey-player.js runtime.

You can export animations in a .askey format and play it everywhere in the web with the companion askey-player.js or run it in the terminal using the cli tool.

• Offline-ready PWA.
• Animated input support with adjustable frame limits, skip rates, and playback speed.
• Control over gradients, brightness/contrast and more...
• Background color picker.
• One-click exports to TXT, SVG, PNG, WebP, GIF, APNG, or JSON for animations.

Init	ASCII Conversion

# 1. Install dependencies
npm i

# 2. Start the dev server (http://localhost:5173)
npm run dev

# 3. Run the full type + lint suite (optional)
npm run check && npm run lint

The dev server hot-reloads when you edit files inside src/. Use npm run check -- --watch for incremental accessibility + type checks while iterating on components.

1. npm run check – type and accessibility safety net.
2. npm run lint – ESLint + Prettier formatting.
3. npm run build – emits optimized client, server, and service worker bundles.
4. npm run test - Run test suites.
5. Deploy the adapter output (.vercel/output, .netlify, or build) to your host of choice.

• "Universal" export file for ASCII animations.
• Offline support with service workers.
• C# terminal player for .askey files. (see: askey-cli)
• Implement dithering algorithms options.
• Fix render bug in certain animations with certain backgrounds/complex color combinations.
• Increased test coverage.
• Animated WebP support.
• Video support maybe?
• Build a site to share and download asꄗ animations.

A .NET CLI tool will be available to run ASCII animations directly in the terminal using exported .askey files.

• SvelteKit 2 with Vite 7
• TypeScript 5 + ESLint 9 + Prettier 3
• Custom service worker for offline caching

1. Fork and clone the repo.
2. Create a feature branch off main.
3. Add or update tests for your change when possible.
4. Run npm run lint && npm run check && npm run test.
5. Open a PR with screenshots or GIFs for UI tweaks.
