WASIMAGE
Combines a Javascript and WASM file into a single executable polygot PNG+HTML file.
Usage:
cargo install wasimage
wasimage --wasm-file my.wasm --js-file my.js
- This will generate
index.png.html
which will automatically unpack and execute, loading itself as a PNG and extracting the data from there
NOTE: By default file access is blocked in Chrome, so you can't test this locally unless you spin up an HTTP server. Start Chrome with the --allow-file-access-from-file
to remove this restriction.
The Javascript will receive the WASM as a regular array in arguments[0]
. See the examples
folder for an example.
You can also pass --max-width
to restrict the width of the generated PNG.
Inspiration and parts of the loader code come from pnginator by Gasman et al.
