IDirectFBSurface   SetSrcColorMatrix

Set the source color matrix.

DFBResult SetSrcColorMatrix (
  IDirectFBSurface   * thiz,
  const s32   * matrix
);

Enable usage of this matrix by setting DSBLIT_SRC_COLORMATRIX via IDirectFBSurface::SetBlittingFlags().

The matrix consists of 4x3 fixed point 16.16 values. The order in the array is from left to right and from top to bottom.

All RGB values will be transformed:

              R' = R * v0 + G * v1 + B * v2  + v3
              G' = R * v4 + G * v5 + B * v6  + v7
              B' = R * v8 + G * v9 + B * v10 + v11
