Graphics2D.getComposite介绍

[英]Returns the current Composite in the Graphics2D context.
[中]返回Graphics2D上下文中的当前Composite。

代码示例

代码示例来源：origin: graphhopper/graphhopper

public void makeTransparent(Graphics2D g2) {
  Color col = g2.getColor();
  Composite comp = null;
  // force transparence of this layer only. If no buffering we would clear layers below
  if (buffering) {
    comp = g2.getComposite();
    g2.setComposite(AlphaComposite.Clear);
  }
  g2.setColor(new Color(0, 0, 0, 0));
  g2.fillRect(0, 0, bounds.width, bounds.height);
  g2.setColor(col);
  if (comp != null) {
    g2.setComposite(comp);
  }
}

   Composite old = g2.getComposite();
   g2.setComposite(AlphaComposite.getInstance(AlphaComposite.SRC_OVER, 0.5f));
   g2.setColor(Color.BLUE);

   // g2.drawRect(zoomBoxStartX, zoomBoxStartY, zoomBoxWidth, zoomBoxHeight);
