包路径：org.eclipse.swt.graphics.GC
类名称：GC
方法名：setTransform
GC.setTransform介绍
[英]Sets the transform that is currently being used by the receiver. If the argument is null, the current transform is set to the identity transform.
This operation requires the operating system's advanced graphics subsystem which may not be available on some platforms.
[中]设置接收器当前正在使用的变换。如果参数为null，则当前转换将设置为标识转换。
此操作需要操作系统的高级图形子系统，该子系统在某些平台上可能不可用。
