Look at the texture interface - you can access the underlying surfaces of a texture.

I try to point people to the docs rather than spell things out. This is the kind of case where that becomes more important. If you use copyrects in this manner, pay careful attention to all of the attributes of your texture.

A careful perusal of the texture interface is probably a good idea here...

Sigh...

search on "IDirect3DTexture8" - the texture interface... Although other searches will get you to the same place very quickly. Click on any link to IDirect3DTexture8" - the texture interface.

Anyway, if you search for IDirect3DTexture8 (the texture interface), the topmost hit will be the entry for IDirect3DTexture8 (the texture interface) If you click on that, you will get the documentation for the texture interface (IDirect3DTexture8).

Very near the top to that page, you will find a table that lists all the methods of the texture interface (IDirect3DTexture8). Most of them address your problem.

GetLevelDesc gives you a description of the surface of the texture (aha! a surface)

GetSurfaceLevel returns that surface to you (aha, a surface again)

Come on now, the docs for CopyRects includes information about levels, surfaces, and textures. I don't think it's unreasonable to assume that you could find the docs for the texture interface. When you have a question about a particular interface, look at that interface! (as stated in the original reply)

Sorry for the rant, but I can't think of a more direct way of giving you the correct information short of cutting and pasting the docs themselves. If you have trouble navigating the docs, say so, but don't accuse me of beating around the bush. I could reinterpret the docs for you, but that would be a lower fidelity version of the info that you already have access to.
Spoon feeding you with information is a dangerous thing because you'll never learn the limitations, things to look out for, etc.

For future reference:

The arrangement of the docs is such that I wouldn''t expect CopyRects to expound on the texture interface because CopyRects is not about textures.

In general, questions about interfaces are answered in the interface docs. So, copyrects talks about surfaces of textures. Your first question should be "How do I get a surface from a texture". The interface of an object supplies access to info and attributes of that object, so your question becomes "What method of the interface gives me a surface?" At that point you look at the texture interface.

The point to all of these posts was to try to get you to look at the docs. You are having problems with textures, look at the texture interface.

There''s no news flash there, I wouldn''t expect the docs for IDirect3DDevice8 to go into detail about textures. I''m not saying this to argumentative, I''m trying to give you some insight into how the docs are arranged. They aren''t perfect, but they do have a logical layout.
