IsChannelIdentity method

  • Article

Determines whether the application of a channel's table will have any effect.

Syntax

HRESULT retVal = object.IsChannelIdentity(pSampleBools);

Parameters

  • pSampleBools [out]
    Type: DXBASESAMPLE

    Pointer to a DXBASESAMPLE structure that tells whether a color's lookup table is enabled.

Remarks

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.
