AffineTransformを使用してアラビア数字を回転して時計盤に配置する

for (String txt : arabicNumerals) {
  double m00 = at.getScaleX();
  double d = m00 > 0d || Math.abs(m00) < 0.0001 ? 1d : -1d;
  AffineTransform si = AffineTransform.getScaleInstance(d, d);
  Shape s = getTextLayout(txt, font, frc).getOutline(si);
  Rectangle2D r = s.getBounds2D();
  double tx = r.getCenterX();
  double ty = radius - hourMarkerLen - r.getHeight() + r.getCenterY();
  Shape t = AffineTransform.getTranslateInstance(-tx, -ty)
      .createTransformedShape(s);
  g2.fill(at.createTransformedShape(t));
  at.rotate(Math.PI / 6d);
