Build WasmEdge With WasmEdge-Image Plug-in
The WasmEdge Image plug-in is a software component that extends the functionality of the WasmEdge runtime, enabling it to load and decode JPEG and PNG images and convert them into tensors. This plug-in is useful for developers who need to process image data within their WebAssembly applications.
Prerequisites
The prerequisites of the WasmEdge-Image plug-in is the same as the WasmEdge building environment on the Linux platforms or MacOS platforms.
If developers build with their own environment, please ensure the zlib and libboost-all-dev are installed.
sudo apt update
sudo apt install zlib1g-dev libboost-all-dev
On MacOS platforms, the libjpeg and libpng are required.
brew install jpeg-turbo libpng
Build WasmEdge with WasmEdge-Image Plug-in
To enable the WasmEdge WasmEdge-Image, developers need to building the WasmEdge from source with the cmake option -DWASMEDGE_PLUGIN_IMAGE=On.
cd <path/to/your/wasmedge/source/folder>
cmake -GNinja -Bbuild -DCMAKE_BUILD_TYPE=Release -DWASMEDGE_PLUGIN_IMAGE=On
cmake --build build
# For the WasmEdge-Image plug-in, you should install this project.
cmake --install build
If the built wasmedge CLI tool cannot find the WasmEdge-Image plug-in, you can set the WASMEDGE_PLUGIN_PATH environment variable to the plug-in installation path (such as /usr/local/lib/wasmedge/, or the built plug-in path build/plugins/wasmedge_image/) to try to fix this issue.
Then you will have an executable wasmedge runtime under /usr/local/bin and the WasmEdge-Image plug-in under /usr/local/lib/wasmedge/libwasmedgePluginWasmEdgeImage.so after installation.
