仅使用libPNG将PNG纹理加载到OpenGL

I'm rather new to OpenGL coding, I know as much as is taught in the basic tutorials I've looked at.

I've seen quite a few other questions about this but I'm wondering specifically about libPNG and libPNG only, unless another library is absolutely necessary.I'm rather new to OpenGL coding, I know as much
