Asciigen-WASM is a zig-to-wasm implementation inspired by @seatedro's Asciigen. The WebGPU version is still experimental.

Key Features

• Image Conversion: Transform images into ASCII art with customizable options
• Text Styling: Convert images to ASCII text with adjustable size and brightness
• Video Processing: Convert videos to ASCII art videos
• Camera Support: Use your device's camera as an input source
• Sharing: Share your creations with others (images < 0.5MB)
• Mobile Support: Fully responsive with pinch and zoom functionality. FFmpeg WASM may crash due to page size limits.

Uses

• Svelte
• WebAssembly (zig-to-wasm)
• WebGPU (experimental)
• Cloudflare Pages
• Cloudflare Turnstile (for sharing api)
• Web Workers
• Offscreen Canvas
• FFmpeg WASM
• Mediainfo.JS WASM

Project Structure

The project is divided into three main components:

1. zig-to-wasm: WebAssembly core functionality
2. Site: Svelte-based frontend
3. Sharing API: Backend for sharing functionality

Getting Started

1. Clone the repository
2. Navigate to each component's directory for specific setup instructions
3. Deploy the site using Cloudflare Pages for a 100% free hosting solution

Sharing API

• Free to use for original images < 0.5MB
• Images are re-rendered into ASCII on the user's device
• Utilizes free GCP credits, Bun + SQLite, and Cloudflare services
• If the server crashes, it crashes 🤷‍♂️
