• Description This is a C++ program to rotate the input file(image) by the use of wrafAffine funtion which is inbuilt in the opencv library. This method accepts the following parameters − src − A Mat object representing the source (input image) for this operation. dst − A Mat object representing the destination (output image) for this operation. rotationMatrix − A Mat object representing the rotation matrix. size − A variable of the type integer representing the size of the output image.
