PNG files structure

Question

I've already learned how to generate BMP images based on the BMP files structure (here and here).

Now I'm looking for the PNG file structure but I haven't found any good explanations.

Do you know where I can find this explanation with schemes as well?

The complete specification is available here: http://www.libpng.org/pub/png/spec/1.2/png-1.2.pdf

Note that the PNG format is much more complex than BMP, since it allows compression, etc.

What about Wikipedia's explanation? It seems to be written very well and is very easy to understand. There's also the specification, which goes into everything.

Yes, Wikipedia has a good explanation, too. But the specification you posted the link is more complete. Thank you – Danilo Valente Jul 18 '12 at 02:50
