invertAsync function

Future<(double, Mat)> invertAsync(
  1. InputArray src, {
  2. OutputArray? dst,
  3. int flags = DECOMP_LU,
})

Invert finds the inverse or pseudo-inverse of a matrix.

Implementation

Future<(double rval, Mat dst)> invertAsync(
  InputArray src, {
  OutputArray? dst,
  int flags = DECOMP_LU,
}) async {
  dst ??= Mat.empty();
  final p = calloc<ffi.Double>();
  return cvRunAsync0(
    (callback) => ccore.cv_invert(src.ref, dst!.ref, flags, p, callback),
    (c) {
      final rval = p.value;
      calloc.free(p);
      return c.complete((rval, dst!));
    },
  );
}
