IDirect3DRMTexture2

The IDirect3DRMTexture2 interface is an extension of the IDirect3DRMTexture interface. IDirect3DRMTexture2::InitFromResource2 allows resources to be loaded from DLLs and executables other than the currently executing file. In addition, IDirect3DRMTexture2 has two new methods. The IDirect3DRMTexture2::InitFromImage method creates a texture from an image in memory. This method is equivalent to the IDirect3DRM::CreateTexture method. The IDirect3DRMTexture2::GenerateMIPMap method generates a mipmap from a source image.

To avoid unnecessary delays when creating textures, hold onto textures you want to use again, instead of creating them each time they're needed. For optimal performance, use a texture surface format that is supported by the device you are using. This will avoid a costly format conversion when the texture is created and any time it changes.

See the remarks in IDirect3DRM2::LoadTexture for an example showing how to keep a reference to textures loaded in a texture callback through IDirect3DRM2::LoadTexture.

For a conceptual overview, see IDirect3DRMTexture and IDirect3DRMTexture2.

The methods of the IDirect3DRMTexture2 interface can be organized into the following groups:

The IDirect3DRMTexture2 interface, like all COM interfaces, inherits the IUnknown interface methods. The IUnknown interface supports the following three methods:

AddRef

QueryInterface

Release

In addition, the IDirect3DRMTexture2 interface inherits the following methods from the IDirect3DRMObject interface:

AddDestroyCallback

Clone

DeleteDestroyCallback

GetAppData

GetClassName

GetName

SetAppData

SetName

You can create an IDirect3DRMTexture2 object by calling IDirect3DRM2::CreateTexture or IDirect3DRM2::CreateTextureFromSurface.
