I know how to create an OpenGL texture and give that texture data through a byte buffer, but is there a way to retrieve that data back? I'm looking to have the ability to extract the byte buffer back from the texture so that I can do things like serialize the texture for both saving and loading..... Any ideas?

You can use glGetTexImage.

EDIT: And glGetTexLevelParameter* may be useful if you need to get info such as the width, height, and internal format first.
