TransformManager为Flash应用程序提供了直观的交互式缩放、旋转和平移功能。用户点击目标显示对象后，将出现选择框及八个操作手柄用于缩放或旋转。鼠标置于缩放手柄外侧时，光标变化提示进入旋转模式。用户可通过Shift键多选对象，并约束比例或限定旋转角度。

TransformManager makes it easy to add interactive scaling/rotating/moving of DisplayObjects to your Flash application. It uses an intuitive interface that’s similar to most modern drawing applications. When the user clicks on a managed DisplayObject, a selection box will be drawn around it along with 8 handles for scaling/rotating. When the mouse is placed just outside of any of the scaling handles, the cursor will change to indicate that they’re in rotation mode. Just like most other applications, the user can hold down the SHIFT key to select multiple items, to constrain scaling proportions, or to limit the rotation to 45 degree increments.
