If you are interested in learning more about the PNG format, there are several
good resources available online.
PNG Home Page
http://www.cdrom.com/pub/png/
This site is written and maintained by Greg Roelofs, one of the creators of the
PNG format. It contains a complete history of PNG’s birth, descriptions of its
features, and up-to-date lists of applications that support the new format. It
also includes a copy of the PNG Specification and the official PNG extensions
documents (as well as the draft MNG Spec). All of it is written with so much
enthusiasm that you can’t help but become a PNG fan! It is the source of
much of the information in this chapter.
PNG Specification
http://www.w3.org/TR/png.html
This is the complete PNG specification published at the W3C web site. For a
technical document, it is very user-friendly to nonprogrammers and offers
detailed information on how PNGs work, as well as some useful background
information and tutorials.
