- Description
The TDx_DrawSurface::GetLOD method will return the maximum level of detail (LOD) currently set for a managed mipmap.
Calling this method on a surface without DDSCAPS2_TEXTUREMANAGE set will merely result in a DDERR_INVALIDOBJECT error being returned.
If successful the MaxLOD parameter will contain a number indicating the largest mipmap level in the chain the TDx_3D texture manager should display.
For example, if this method returned a 3 in the MaxLOD parameter, it would indicate that only mipmaps of level 3 or smaller should be displayed.
If the method call fails, the OnError event will be triggered with one of the following values:
DDERR_INVALIDOBJECT
DDERR_INVALIDPARAMS
- Parameters
MaxLOD
The MaxLOD parameter will reference the maximum level of detail set for the mipmap chain if the method call succeeds.
