The IBuffer interface wraps the source textures and the destination surface. Your transform typically will not call methods on this interface directly, but instead will pass it to the GetSurface or GetTexture function to get a source or destination surface or texture. However, the interface is documented for completeness.
The object that underlies this interface also exposes the ISurface interface.
In addition to the methods inherited from IUnknown, the IBuffer interface exposes the following methods.
| Method | Description |
| CopyTo | Copies a buffer to another buffer. |
| get_Flags | Retrieves information about the buffer. |
