Hi,
Why invent a new blitting flag? We have matrix transformations in the
API! This is how I have done it...
I.e.
/* reflection against y */
static const s32 y_mat[9] = {
-DFB_FIXED_POINT_ONE, 0, 0,
0, DFB_FIXED_POINT_ONE, 0,
0, 0, DFB_FIXED_POINT_ONE
};
/* reflection against x */
static const s32 x_mat[9] = {
DFB_FIXED_POINT_ONE, 0, 0,
0, -DFB_FIXED_POINT_ONE, 0,
0, 0, DFB_FIXED_POINT_ONE
};
DFBCHECK (dst->SetRenderOptions (dst, DSRO_MATRIX));
DFBCHECK (dst->SetMatrix (dst, y_mat));
DFBCHECK (dst->SetMatrix (dst, x_mat));
In the same way all the existing rotation flags could be supported,
which is why I actually think they should be removed long-term, or at
least be deprecated...
Cheers,
Andre'
