getOptimalNewCameraMatrix function

(Mat, Rect) getOptimalNewCameraMatrix(
  1. InputArray cameraMatrix,
  2. InputArray distCoeffs,
  3. (int, int) imageSize,
  4. double alpha, {
  5. (int, int) newImgSize = (0, 0),
  6. bool centerPrincipalPoint = false,
})

GetOptimalNewCameraMatrixWithParams computes and returns the optimal new camera matrix based on the free scaling parameter.
