🖼️ img-toolkit-rust (Staging)

img-toolkit-rust is a high-performance image processing library rewritten in Rust (WASM) from the original TypeScript-based img-toolkit. Leveraging WebAssembly, this version provides faster, more efficient, and reliable image manipulation directly in browsers.

✨ Features

• ⚡ Fast & Efficient: Powered by Rust and WebAssembly.
• 📸 Supports JPEG, PNG, WebP formats.
• 📐 Resizing with automatic aspect-ratio handling.
• 🎚️ Adjust brightness easily.
• 🔍 Multiple resampling filters (Nearest, Triangle, CatmullRom, Gaussian, Lanczos3).
