#### 返回值

返回画布上的坐标，数据结构同参数 `point`。

### parsePoints

说明：将一组 0 - 1 范围内的点转化为画布上的实际坐标。

#### 参数

- `points` **Array<{x: number, y: number}>**

`point` 的数组，表示一组归一后的坐标。

如：

```js
[
{ x: 0.3, y: 0.34 },
{ x: 0.3, y: 0.34 }
]
```

#### 返回值

返回对应的画布上的坐标点数组，数据结构同 `points`。

### parsePath

将归一化的 path 转为基于画布坐标的 path.

#### 参数

- `path` **Path**

连接各个关键的路径，例如：`[[ 'M', 0, 0 ], [ 'L', 1, 1 ]]`。

- `isCircle` **boolean**

是否是极坐标。如果是极坐标，则把 path 转换为圆弧。

#### 返回值 **Path**

返回基于画布坐标的 path。
