如何使用JAVA控制渲染质量 [英] How to control rendering quality using JAVA

问题描述

我有一个像这样的简单绘图画布:

I have simple drawing canvas like this:

public class DrawingCanvas extends JPanel

    private BufferedImage image;

    @Override
    public void paintComponent(Graphics g) {
        super.paintComponent(g);


            image = new BufferedImage(this.getWidth(), this.getHeight(), BufferedImage.TYPE_INT_ARGB);

            Graphics2D g2 = (Graphics2D) image.getGraphics();

            // draw some items....                

            g2.dispose();
            g.drawImage(image, 0, 0, null);
   }
}

我想问你，是否可以设置一些渲染质量?

I want to ask you, if I can set some render quality?

例如Antialiasing ..我要使用 BEST 渲染质量.

For example Antialiasing.. I want use BEST render quality.

如何?

推荐答案

看看

Have a look at RenderingHints. You can set them with calling g2.setRenderingHint(RenderingHints.Key hintKey, Object hintValue).

以此，您可以更改渲染质量的不同设置，例如(文本)抗锯齿，alpha插值等.

With this you can alter different settings for the render quality, like (text)anti-aliasing, alpha-interpolation etc.

对于抗锯齿:

g2.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON)

其他键和值很不言自明.

The other keys and values are pretty self-explanatory.
