| `rust-j2k` | J2K/JP2 through `RustJ2kCodec` | none; exact pure-Rust `j2k` 0.8.1 |
| `rust-skia` | BMP/GIF/ICO/JPEG/PNG/WBMP/WebP through `RustSkiaTextureCodec` | none; exact pure-Rust `skia-rs-codec` 0.3.0 and `image-webp` 0.2.4 |
| `rust-j2k` (default) | J2K/JP2 through `RustJ2kCodec` | none; exact pure-Rust `j2k` 0.8.1 |
