PHP PNG Chunks
==============

[](#php-png-chunks)

It reads and writes PNG chunks.

This library doesn't do anything with image data. If you care about image data you want something else.

But it can be used to look at the structure and raw chunk data of PNG files.

e.g. if you want to insert or look at metadata.
