Any modifications to leader annotation that change its position affect the position of the endpoint of the associated leader. Also, rotating the annotation causes the leader hook line (if any) to rotate.
任何会改变引线注释位置的修改都会影响到关联引线的端点位置。另外，旋转注释也会使引线基线（如果有）随之旋转。
Resize a leader by scaling it. If you scale the leader, the annotation stays in the same position relative to the leader endpoint but is not scaled. In addition to scaling, you can also move, mirror, and rotate a leader. Use the TransformBy method to edit the leader. Modify the associated annotation using its member properties and methods
要调整引线的大小，可以将其缩放。如果缩放引线，则注释将保持与引线端点的相对位置不变，而不会进行缩放。除了缩放以外，还可以移动、镜像和旋转引线。使用 TransformBy 方法来编辑引线。也可以使用它的成员属性和方法修改关联注释。
