Determines whether the application of a channel's table will have any effect.
HRESULT IsChannelIdentity( DXBASESAMPLE *pSampleBools );
- [out] Pointer to a DXBASESAMPLE structure that tells whether a color's lookup table is enabled.
Returns an HRESULT value that depends on the implementation of the interface.
A TRUE or FALSE value is stored in each of the color components — alpha, red, green, and blue — of the returned structure. If a component has a return value of TRUE, that color is unaffected by a call to IDXLookupTable::ApplyTables.
