## libtiff.wasm Release
Production-ready TIFF image processing library for WebAssembly.
### Features
- ✅ Complete TIFF format support (read/write)
- ✅ Multiple compression formats (LZW, ZIP, PackBits, JPEG*, WebP*)
- ✅ SIMD optimization for 2-4x performance improvement
- ✅ Progressive loading for large TIFF files
- ✅ Multi-page TIFF support
- ✅ Professional workflow integration
- ✅ Integration with zlib.wasm, libjpeg-turbo.wasm, libwebp.wasm
### Downloads
- `libtiff-wasm-complete.tar.gz` - Complete package with SIMD and fallback builds
- `libtiff-wasm-simd.tar.gz` - SIMD-optimized build only
- `libtiff-wasm-fallback.tar.gz` - Fallback build only
### Installation
```bash
npm install @superstruct/libtiff.wasm
```
*Optional dependencies require separate installation of ecosystem libraries.
