[Squoosh] is an image compression web app that allows you to dive into the advanced options provided
by various image compressors.
Squoosh will be an image compression web app that allows you to dive into the
advanced options provided by various image compressors.
# Privacy
Google Analytics is used to record the following:
* [Basic visit data](https://support.google.com/analytics/answer/6004245?ref_topic=2919631).
* Before and after image size once an image is downloaded. These values are rounded to the nearest
kilobyte.
Image compression is handled locally; no additional data is sent to the server.
# Building locally
Clone the repo, and:
```sh
npm install
npm run build
```
You can run the development server with:
```sh
npm start
```

This will build two files: `<codec name>_<enc or dec>.js` and `<codec name>_<enc or dec>.wasm`. It will most likely be necessary to set [`Module["locateFile"]`](https://kripken.github.io/emscripten-site/docs/api_reference/module.html#affecting-execution) to successfully load the `.wasm` file. When the `.js` file is loaded, a global `<codec name>_<enc or dec>` is created with the same API as an [Emscripten `Module`](https://kripken.github.io/emscripten-site/docs/api_reference/module.html).

# OptiPNG
- Source: <https://sourceforge.net/project/optipng>
- Version: v0.7.7
## Dependencies
- Docker
## Example
See `example.html`
## API
### `int version()`
Returns the version of optipng as a number. va.b.c is encoded as 0x0a0b0c
### `ArrayBuffer compress(std::string buffer, {level})`;
`compress` will re-compress the given PNG image via `buffer`. `level` is a number between 0 and 7.
### `void free_result()`
Frees the result created by `compress()`.

//! This is a module that provides `malloc` and `free` for `libdeflate`.
//! These implementations are compatible with the standard signatures
//! but use Rust allocator instead of including libc one as well.
//!
//! Rust allocator APIs requires passing size and alignment to the
//! `dealloc` function. This is different from C API, which only
//! expects a pointer in `free` and expects allocators to take care of
//! storing any necessary information elsewhere.
//!
//! In order to simulate C API, we allocate a `size_and_data_ptr`
//! of size `sizeof(usize) + size` where `size` is the requested number
//! of bytes. Then, we store `size` at the beginning of the allocated
//! chunk (within those `sizeof(usize)` bytes) and return
//! `data_ptr = size_and_data_ptr + sizeof(usize)` to the calleer:
//!
//! [`size`][...actual data]
//! -^------------------ `size_and_data_ptr`
//! ---------^---------- `data_ptr`
//!
//! Then, in `free`, the caller gives us `data_ptr`. We can subtract
//! `sizeof(usize)` back and get the original `size_and_data_ptr`.
//! At this point we can read `size` back and call the Rust `dealloc`
//! for the whole allocated chunk.
//!
//! I've raised an upstream issue to hopefully make this easier in
//! future: https://github.com/ebiggers/libdeflate/issues/62
