ellipse方法

void ellipse(
  1. num x,
  2. num y,
  3. num radiusX,
  4. num radiusY,
  5. num rotation,
  6. num startAngle,
  7. num endAngle,
  8. bool? anticlockwise
)

实现

void ellipse(num x, num y, num radiusX, num radiusY, num rotation,
    num startAngle, num endAngle, bool? anticlockwise) native;
