Today I present to you a library I have been working on: libPNGimage The library allows you to decode and encode PNG images. Please note that at the time of writing, it is missing some features and is not therefore fully standards-compliant.
The library makes use of slightly-modified versions of DeflateLua and CRC32Lua by David Manura, which are both licensed under MIT. As for libPNGimage itself, as long as you leave my little credits header there, you can do whatever you want with it .
I have a quick demonstration application 'pngview' which I will release to the forums shortly afte
