Replacement for ippiAddRotateShift()?

[Bayer__Stefan]

I have to port some legacy code from IPP 7.0 to current IPP 9.0. Unfortunately the former function

ippiAddRotateShift (double xCenter, double yCenter, double angle, double * xShift, double * yShift) 

is deleted without replacement in IPP 9.0:

What's the calculation rule of that function? How can i calculate xShift and yShift?

Thanks in advance for your help!

Hi Stefan,

Please use the following code to compute xShift and yShift:

void AddRotateShift(double xCenter, double yCenter, double angle, double *xShift, double *yShift)
{
    double  sx, sy;

    ippiGetRotateShift(xCenter, yCenter, angle, &sx, &sy);
    *xShift += sx;
    *yShift += sy;

    return;
}

Thanks,
Valentin
