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;
