Java的的BasicStroke＆QUOT;模糊＆QUOT; [英] Java BasicStroke "Fuzzy"

问题描述

我试图写一个简单的小程序漆使用Java，但我在使用的BasicStroke 麻烦。最初，我的计划是试图以某种方式绘制宽度的线，但显然API不支持。

我试着用的BasicStroke ，但结果只是一个模糊的一塌糊涂。我怎样才能解决这个问题细毛？

 私人无效mousedrag_hook（点对点）
    {
        如果（开始== NULL）
            开始=点;            结束=点;            Graphics2D的G2D =（Graphics2D的）applInstance.buffer_g;
            g2d.setStroke（新的BasicStroke（7））;            //g2d.fillOval(point.x  -  5，point.y  -  5，10，10）;
            g2d.drawLine（start.x，start.y，end.x，end.y）;
            applInstance.repaint（）;            开始=结束;
    }
 

解决方案

不要忘了的 的RenderingHints ：

  @覆盖
公共无效的paintComponent（图形G）{
    super.paintComponent方法（G）;
    Graphics2D的G2D =（Graphics2D的）克;
    g2d.setRenderingHint（
        RenderingHints.KEY_ANTIALIASING，
        RenderingHints.VALUE_ANTIALIAS_ON）;
    ...
}
 

I'm trying to write a simple paint applet with Java, but I'm having trouble with BasicStroke. Initially, my plan was to try to somehow draw a line with a width, but the API apparently doesn't support that.

I tried using BasicStroke, but the result is just a fuzzy mess. How can I fix this fuzz problem?

private void mousedrag_hook(Point point)
    {
        if(start == null)
            start = point;

            end = point;

            Graphics2D g2d = (Graphics2D)applInstance.buffer_g;
            g2d.setStroke(new BasicStroke(7));

            //g2d.fillOval(point.x - 5, point.y - 5, 10, 10);
            g2d.drawLine(start.x, start.y, end.x, end.y);
            applInstance.repaint();

            start = end;
    }

解决方案

Don't forget the RenderingHints:

@Override
public void paintComponent(Graphics g) {
    super.paintComponent(g);
    Graphics2D g2d = (Graphics2D) g;
    g2d.setRenderingHint(
        RenderingHints.KEY_ANTIALIASING,
        RenderingHints.VALUE_ANTIALIAS_ON);
    ...
}
