compose method

PerspectiveTransform compose(
  1. PerspectiveTransform other
)

Creates a PerspectiveTransform that is the composition of this transformation and a given other transformation.

Implementation

PerspectiveTransform compose(PerspectiveTransform other) {
  final A = other._matrix.toList();
  final B = _matrix.toList();
  final result = List<double>.filled(9, 0);
  for (int i = 0; i < 3; i++) {
    for (int j = 0; j < 3; j++) {
      for (int k = 0; k < 3; k++) {
        result[i * 3 + j] += A[i * 3 + k] * B[k * 3 + j];
      }
    }
  }

  return PerspectiveTransform(result);
}
