如何在Java中绘制一个体面的Circle [英] How to draw a decent looking Circle in Java

问题描述

我尝试过使用与高度和宽度相等的方法drawOval，但随着直径的增加，圆看起来变得更糟。无论大小如何，我都可以做一个体面的圈子。如何在java或其他方法中实现反锯齿。

I have tried using the method drawOval with equal height and width but as the diameter increases the circle becomes worse looking. What can I do to have a decent looking circle no matter the size. How would I implement anti-aliasing in java or some other method.

推荐答案

事实证明，Java2D假设是你正在使用的）已经很不错了！这里有一个体面的教程： http：//www.javaworld .com / javaworld / jw-08-1998 / jw-08-media.html

As it turns out, Java2D (which I'm assuming is what you're using) is already pretty good at this! There's a decent tutorial here: http://www.javaworld.com/javaworld/jw-08-1998/jw-08-media.html

重要的一行是：

The important line is:

graphics.setRenderingHint(RenderingHints.KEY_ANTIALIASING,
                          RenderingHints.VALUE_ANTIALIAS_ON);
