invertAffineTransform function

Mat invertAffineTransform(
  1. InputArray M, {
  2. OutputArray? iM,
})

Inverts an affine transformation. The function computes an inverse affine transformation represented by 2×3 matrix M: The result is also a 2×3 matrix of the same type as M.

Implementation

Mat invertAffineTransform(InputArray M, {OutputArray? iM}) {
  iM ??= Mat.empty();
  cvRun(() => cimgproc.cv_invertAffineTransform(M.ref, iM!.ref, ffi.nullptr));
  return iM;
}
