The C/C++ encoder and transcoder libraries can be compiled to native code or WebAssembly (web or WASI), and all encoder/transcoder features can be accessed from JavaScript via a C++ wrapper library which optionally supports [WASM multithreading](https://web.dev/articles/webassembly-threads) for fast encoding in the browser. [WASM WASI](https://wasi.dev/) builds, for the command line tool and the encoder/transcoder as a WASI module using a pure C API, are also supported. @@ -101,7 +101,7 @@ Weight Grid DCT can be disabled; however, supercompression remains available wit Supports adaptive deblocking when transcoding from larger block sizes; this can be disabled using a transcoder flag. -XUASTC LDR supports the following ASTC configurations: L/LA/RGB/RGBA CEMs; base+scale or RGB/RGBA direct; base+offset CEMs; Blue Contraction encoding; 1–3 subsets; all partition patterns; and single- or dual-plane modes.
