帮助我如何解决它，[尝试执行我的代码时的警报窗口][1]
注意到调试很好并且成功但是当尝试执行代码时，我在输出窗口中收到一条消息；Exception non gérée à 0x100e3cf2 dans shervinemami.exe : 0xC0000094: Integer 除以零..这意味着有一个除以零的异常，这是代码：
IplImage* LOULILI::cropFace(IplImage*image, CvPoint eye_left, CvPoint eye_right,double offset_pct[2], CvSize dest_sz)

//calculate offsets in original image

double offset_v = offset_pct[1]*dest_sz.height;
//get the direction

eye_directionX= double(eye_right.x - eye_left.x);

// calc rotation angle in radians

rotation = double(-atan2(eye_directionY,eye_directionX )*180/PI);
// distance between them
double dist = distancePoints(eye_left, eye_right);
//calculate the reference eye-width

//scale factor
