# OptiPNG
|
||||
|
||||
- Source: <http://optipng.sourceforge.net/>
|
||||
- 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
