IDirect3DTexture Interface Method Groups
Applications use the methods of the IDirect3DTexture interface to retrieve and set the properties of textures. The methods can be organized into the following groups:
Handles GetHandle
Initialization Initialize
IUnknown AddRef
Loading Load
Palette information PaletteChanged
All COM interfaces inherit the IUnknown interface methods, which are listed in the "IUnknown" group above. These three methods allow additional interfaces to be added to the Direct3DTexture object without affecting the functionality of the original interface.
The Direct3DTexture object is obtained through the appropriate call to the IDirect3D::QueryInterface method from a DirectDrawSurface object that was created as a texture map.
