delta

用于计算线段（LineSegment）在x和y轴上的增量。

语法

lineSegment.delta()

返回值

返回一个对象，包含以下属性：
- x: x轴上的增量。
- y: y轴上的增量。

示例

const lineSegment = new LineSegment({ x1: 0, y1: 0, x2: 3, y2: 4 });
const delta = lineSegment.delta();
console.log(delta); // { x: 3, y: 4 }

注意事项

delta 方法返回的对象的属性值可能是负数。
如果线段的结束点在起始点左侧或上方，则返回的增量值为负数。
