If you're trying to go cross-platform with Mac OS X and WinXP and only need
libpng for PNG support, you could forego libpng and QuickTime, since both OSes
support reading and writing PNG data.  Use CoreGraphics on Mac and GDI+ on
Windows.

Quoting P McIlroy <email@hidden>:

I have an app that currently uses the QuickTime sdk to open png files
on OSX, but uses .bmp files everywhere else.
I would like to make it more portable, using libpng.

I see via Spotlight that there is a  copy in /Developer/SDKs/......./
libPng.dylib

Can I use the methods in this, and get rid of the quicktime stuff
without distributing libpng as part of the app, or do I need to
continue to use Quicktime? Since I need to use libpng methods anyway,
it might be simpler to use the same interface on OS X as well.
