D3DXColorNegative Function

Creates the negative color value of a color value.


D3DXCOLOR *D3DXColorNegative(      

    D3DXCOLOR *pOut,     CONST D3DXCOLOR *pC );


[in, out] Pointer to a D3DXCOLOR structure that is the result of the operation.
[in] Pointer to a source D3DXCOLOR structure.

Return Value

This function returns a pointer to a D3DXCOLOR structure that is the negative color value of the color value.


The input alpha channel is copied, unmodified, to the output alpha channel.

The return value for this function is the same value returned in the pOut parameter. In this way, the D3DXColorNegative function can be used as a parameter for another function.

This function returns the negative color value by subtracting 1.0 from the color components of the D3DXCOLOR structure, as shown in the following example.

pOut->r = 1.0f - pC->r;
