Description:
============
This file describes the compilation of libwebp into a JavaScript decoder
using Emscripten and CMake.
- install the Emscripten SDK following the procedure described at:
https://kripken.github.io/emscripten-site/docs/getting_started/downloads.html
After installation, you should have some global variable positioned to the
location of the SDK. In particular, $EMSCRIPTEN should point to the
top-level directory containing Emscripten tools.
- make sure the file $EMSCRIPTEN/cmake/Modules/Platform/Emscripten.cmake is
accessible. This is the toolchain file used by CMake to invoke Emscripten.
- configure the project 'WEBP_JS' with CMake using:
cd webp_js && \
cmake -DWEBP_BUILD_WEBP_JS=ON \
-DEMSCRIPTEN_GENERATE_BITCODE_STATIC_LIBRARIES=1 \
-DCMAKE_TOOLCHAIN_FILE=$EMSCRIPTEN/cmake/Modules/Platform/Emscripten.cmake \
../
- compile webp.js using 'make'.
- that's it! Upon completion, you should have the webp.js and
webp.js.mem files generated.
The callable JavaScript function is WebPToSDL(), which decodes a raw WebP
bitstream into a canvas. See webp_js/index.html for a simple usage sample
(see below for instructions).
Demo HTML page:
===============
The HTML page webp_js/index.html requires an HTTP server to serve the WebP
image example. It's easy to just use Python for that.
cd webp_js && python -m SimpleHTTPServer 8080
and then navigate to http://localhost:8080 in your favorite browser.
Web-Assembly (WASM) version:
============================
CMakeLists.txt is configured to build the WASM version when using
the option WEBP_BUILD_WEBP_JS=ON. The compilation step will assemble
the files 'webp_wasm.js', 'webp_wasm.wasm' in the webp_js/ directory.
See webp_js/index_wasm.html for a simple demo page using the WASM version
of the library.
You will need a fairly recent version of Emscripten (at least 1.37.8) and of
your WASM-enabled browser to run this version. Consider it very experimental!
Caveat:
=======
- First decoding using the library is usually slower, due to just-in-time
compilation.
- Some versions of llvm produce the following compile error when SSE2 is
enabled.
"Unsupported: %516 = bitcast <8 x i16> %481 to i128
LLVM ERROR: BitCast Instruction not yet supported for integer types larger than 64 bits"
The corresponding Emscripten bug is at:
https://github.com/kripken/emscripten/issues/3788
Therefore, SSE2 optimization is currently disabled in CMakeLists.txt.

Frame Duration: 24 bits (_uint24_)
: The time to wait before displaying the next frame, in 1 millisecond units.
Note the interpretation of frame duration of 0 (and often <= 10) is
implementation defined. Many tools and browsers assign a minimum duration
similar to GIF.
In particular, frame duration of 0 is useful when one wants to update
multiple areas of the canvas at once during the animation.
