Working with PNG Format

Question

I am looking to work with PNG format inside of either C++ or C#. I can't find any documentation on how to convert a PNG into a 2D array of bytes/floats which represent the colors on the image.

What I want to achieve:

• Load Png to array [Width*Height]
• Use PNG as a texture inside of a game

If someone could supply me with any documentation, source code or a C#/C++ library/dll that would be great.

Preferrably as C++ and without using any Windows specific library.

Answer 1

Use libpng, the official PNG library.

Specifically, this page has all of the information on how to open and read.
