compute method

bool compute()

Computes the transformation matrix by solving the two systems of linear equations defined by the control point mappings, if this is possible.

@return true if the transformation matrix is solvable

Implementation

bool compute() {
  List<double> bx = [dest0.x, dest1.x, dest2.x];
  List<double?>? row0 = solve(bx);
  if (row0 == null) return false;
  m00 = row0[0]!;
  m01 = row0[1]!;
  m02 = row0[2]!;

  List<double> by = [dest0.y, dest1.y, dest2.y];
  List<double?>? row1 = solve(by);
  if (row1 == null) return false;
  m10 = row1[0]!;
  m11 = row1[1]!;
  m12 = row1[2]!;
  return true;
}
