Hello,
I'm currently integrating the libDecodeQR library (used to decode QR Codes) in my application in C++ Builder (XE6). I managed to have the openCV 2.4.0 working and was therefore able to compile libDecodeQR.
Unfortunately, when using it (for instance in the code : cvWarpPerspective(spts,dpts,map); with src and dst CvPoint2D32f and map CvMat*), I get either "external exception e06d7363" or "division by zero" error. I'm having trouble knowing which exact line raises the error, while debugging it stops when returning the Scalar in ScalarAll(0), which is used to initialize by default the "fillvall" parameter of cvWarpPerspective :
CV_INLINE CvScalar cvScalarAll( double val0123 )
{
CvScalar* scalar = new CvScalar();
scalar->val[0] = val0123;
scalar->val[1] = val0123;
scalar->val[2] = val0123;
scalar->val[3] = val0123;
return *scalar;
}
Does someone know what may raise this error ?
Thank you
