  [in]      ULONG         uiIndex,
  [in, out] MilMatrix3x2D *pMatrix
);

Parameters

[in] uiIndex

Type: ULONG

A zero based index value indicating the output pin through which to retrieve the affine matrix.

[in, out] pMatrix

Type: MIL_MATRIX3X2D*

When this method returns, contains a pointer to the affine matrix describing the effects transform.
