If you're interested, LDView has two C++ classes that together allow you to
write a PNG via libpng. They have the advantage of being much easier to use
that libpng itself. Take a look in the LDView source at TCImage.{h,cpp} and
TCPngImageFormat.{h,cpp}. They might even compile without modification; they
definitely compile in Linux and Visual Studio.
LDView source can be downloaded from here:

| (...) Hi Travis, I've downloaded LDview, and gotten libpng and zlib built under C++ Builder. What classes do you have for reading and writing PNG files based on libpng. I'd like to give them a look. Thanks, Kevin (20 years ago, 20-Sep-04, to lugnet.cad.dev)
