如何连接多个图像（非常快）

Question

连接多张图片比我的代码更快吗？

BufferedImage bufferedImage = new BufferedImage(64, 64, BufferedImage.TYPE_INT_ARGB);
Graphics2D g2 = bufferedImage.createGraphics();

Image image1 = (new ImageIcon(mypath1).getImage();

Image image2 = (new ImageIcon(mypath2).getImage();

Image image3 = (new ImageIcon(mypath3).getImage();

Image image4 = (new ImageIcon(mypath4).getImage();

g2.drawImage(image4, 0, 0, 32, 32, null);
g2.drawImage(image3, 0, 32, 32, 32, null);
g2.drawImage(image2, 32, 0, 32, 32, null);
g2.drawImage(image1, 32, 32, 32, 32, null);

m_placeableIcon = new ImageIcon(bufferedImage);

我想将我的位图分开存储但在JPanel中我希望有一个实心的位图/图像。
