LuPng

A small PNG decoder/encoder lib extracted from my game engine, Lunacy. It was designed for minimal state overhead and to exclusively use read/write callbacks to make it easier to use PNG data from various sources.

Usage

See example.c

Building

LuPng uses the zlib API for compression and decompression. For convenience this repo also contains miniz, a public domain implementation of the deflate algorithm that exposes the zlib API. However if your project already uses zlib you can tell LuPng to use that instead.

With zlib:

• add lupng.c to your project
• define LUPNG_USE_ZLIB
• link against zlib
• Example: cc example.c lupng.c -DLUPNG_USE_ZLIB -lz

With miniz:

• add lupng.c and miniz.c to your project
• add a miniz header to your include path (there is one provided in the miniz/ directory)
• Example: cc example.c lupng.c -Iminiz/
