用Java重置Graphics2D对象 [英] Reset Graphics2D object in Java

问题描述

我正在用Java进行Graphics2D的实验.但是像往常一样，我被困住了. :P问题是: 假设我有这段代码，

I was experimenting with Graphics2D in Java. But as usual, I am stuck. :P The problem is: Suppose i have this code,

Graphics2D g=(Graphics2D)(this.getGraphics()); //Inside a JFrame
g.rotate(Math.PI/8);
g.drawLine(10, 20, 65, 80);

//I want this one and all following lines to be drawn without any rotation
g.drawLine(120, 220, 625, 180);

有可能吗???我知道一定有办法，但我无法弄清楚.请帮忙.

Is it possible??? I know there must be some way but I am not able to figure it out. Please help.

推荐答案

您要做的就是恢复转换.

What you'll want to do is restore the transform.

尝试

AffineTransform oldXForm = g.getTransform();
g.rotate(...);
g.drawLine(...);

g.setTransform(oldXForm); // Restore transform
g.drawLine(...);
