i am trying to do image forward rotation by using this Point2f vector is it possible to convert point2f into Mat without using wrap affine

double AffineMat[3][3] = { { cos(angle*PI / 180), sin(angle*PI / 180), 0 },
{ -1 * sin(angle*PI / 180), cos(angle*PI / 180), 0 }, { 0, 0, 1 } };

this matrix how to multiply this matrix with mat image and if it possible plz can any body show me how to multiply image with mask ?? plz help me

First you have to create the 2x3 rotation matrix.

cv::Point2f center(((float)imageSize.width * 0.5f), ((float)imageSize.height * 0.5f)); cv::mat RotMap = cv::getRotationMatrix2D( center, Rot, 1.0);

then rotate your image

cv::warpAffine(ImageMatIn, RotatedImageMatOut, RotMap, CameraAvgImage.size(), cv::INTER_LINEAR, cv::BORDER_REPLICATE , cv::Scalar(127,127,127));
