ID3DXContext::GetNumBits

The ID3DXContext::GetNumBits method returns values describing the pixel format of the DirectDrawSurface objects encapsulated by a context object.

HRESULT GetNumBits(
  LPDWORD colorBits,
  LPDWORD depthBits,
  LPDWORD alphaBits,
  LPDWORD stencilBits
); 

Parameters

colorBits

A pointer to the color depth of the current display mode.

depthBits

A pointer to the bit depth of the z-buffer.

alphaBits

A pointer to the bit depth of the alpha buffer

stencilBits

A pointer to the bit depth of the stencil buffer.

Return Values

This method returns S_OK.

Remarks

The stencilBits parameter specifies how many bits are reserved with each pixel of the z-buffer for stencil information.
