Line
绘制横线、斜线、竖线、折线、平滑曲线。
关键属性
width: number
直线的长度。
rotation: number
旋转角度, 取值范围: -180 ~ 180。
ts
// 竖线
width: 100
rotation: 90
计算属性
toPoint: IPointData
目标点(相对元素 起点 的坐标), 自动换算出 width
与 rotation
。
ts
line.toPoint = { x: 0, y: 100 }
console.log(line.toPoint) // {x: 0, y: 100}) 会根据 width 与 rotation 自动换算
points 模式
可通过 points 定义折线。
points: number
[]
通过坐标组 [ x1,y1, x2,y2, ...] 绘制折线。
curve: boolean
| number
是否转换为平滑路径,默认为 false。
可设置 0 ~ 1 控制曲率,默认为 0.5。
closed: boolean
是否自动闭合路径,默认为 false
路径模式
path 优先模式
圆角属性
cornerRadius: number
圆角大小,使折线拐角处变的圆滑。
