Expand description
Cargo package for compiling libpng and vendoring it as static library.
Main goal of the package is providing static library for linking with other C code, like versions of Leptonica.
It provides just rudimentary FFI bindings. More sophisticated bindings would be provided in a separate crate.
If you need to bind libpng with the Rust code directly, you should write your own bindings.
Does not translate C macros from libpng.
Rust FFI bindings not documented. For information on underlying C functions and constants is provided here: https://github.com/pnggroup/libpng/blob/libpng16/libpng-manual.txt
