本文整理了Java中org.eclipse.swt.graphics.Transform.<init>()方法的一些代码示例，展示了Transform.<init>()的具体用法。这些代码示例主要来源于Github/Stackoverflow/Maven等平台，是从一些精选项目中提取出来的代码，具有较强的参考意义，能在一定程度帮忙到你。Transform.<init>()方法的具体详情如下：
包路径：org.eclipse.swt.graphics.Transform
类名称：Transform
方法名：<init>

Transform.<init>介绍

[英]Constructs a new identity Transform.

This operation requires the operating system's advanced graphics subsystem which may not be available on some platforms.
[中]构建一个新的身份转换。
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。

public void setTransform( float translationX, float translationY, int shadowsize, float magnification ) {

 }
 transform = new Transform( gc.getDevice() );
 transform.translate( translationX + shadowsize * magnification, translationY + shadowsize * magnification );
 transform.scale( magnification, magnification );
 gc.setTransform( transform );
 currentMagnification = magnification;
