Graphics samples
绘制二次曲线:
public void paint(Graphics g) {
// TODO 自动生成的方法存根
super.paint(g);
Graphics2D g2=(Graphics2D)g;
QuadCurve2D.Double curle=new QuadCurve2D.Double(60,20,120,100,180,20);
g2.draw(curle);
}
绘制三次曲线:
public void paint(Graphics g) {
// TODO 自动生成的方法存根
super.paint(g);
Graphics2D g2=(Graphics2D)g;
QuadCurve2D.Double curle=new QuadCurve2D.Double(60,20,120,100,180,20);
g2.draw(curle);
}
绘制文本:
public void paint(Graphics g) {
// TODO 自动生成的方法存根
super.paint(g);
String str=new String("静夜思");
int x=50;
int y=50;
g.drawString(str, x, y);
}
设置文本字体:
Font font=new Font(TOOL_TIP_TEXT_KEY, Font.BOLD, 26);
g.setFont(font);
设置文本颜色:
Font font=new Font(TOOL_TIP_TEXT_KEY, Font.BOLD, 26);
g.setFont(font);
设置笔画的粗细:
Graphics2D g2=(Graphics2D)g;
Stroke st=new BasicStroke(20);
g2.setStroke(st);
g2.drawLine(0, 0, 200, 200);
设置笔画样式及连接方式:
Stroke st=new BasicStroke(20,BasicStroke.JOIN_ROUND,BasicStroke.JOIN_BEVEL);
g2.setStroke(st);
设置虚线模式:
float[] arr={10.0f,10.0f};
Stroke st=new BasicStroke(2,BasicStroke.JOIN_ROUND,BasicStroke.JOIN_BEVEL,1.0f, arr,0);
g2.setStroke(st);
