创建要写入的大图像。根据所需的行数和列数来确定其尺寸。
BufferedImage result = new BufferedImage( width, height, //work these out BufferedImage.TYPE_INT_RGB); Graphics g = result.getGraphics();
现在遍历您的图像并绘制它们:
for(String image : images){ BufferedImage bi = ImageIO.read(new File(image)); g.drawImage(bi, x, y, null); x += 256; if(x > result.getWidth()){ x = 0; y += bi.getHeight(); } }最后将其写出到文件中:
ImageIO.write(result,"png",new File("result.png"));
