Java 图片切圆角，消除锯齿

public static BufferedImage setBorderRadius(BufferedImage srcImage, int radius){
    int width = srcImage.getWidth();
    int height = srcImage.getHeight();
    BufferedImage image = new BufferedImage(width, height, BufferedImage.TYPE_INT_ARGB);
    Graphics2D g2d = image.createGraphics();
    g2d.setRenderingHint(RenderingHints.KEY_ANTIALIASING, RenderingHints.VALUE_ANTIALIAS_ON);
    g2d.fillRoundRect(0, 0, width, height, radius, radius);
    g2d.setComposite(AlphaComposite.SrcIn);
    g2d.drawImage(srcImage, 0, 0, width, height, null);
    return image;
