java代码合成图片

下面的bg.png 是背景图，在此图上添加自定义文字123456

String basePath = "/cert/";
BufferedImage bgImage = ImageIO.read(new File(basePath+"bg.png"));
ImageCombiner combiner = new ImageCombiner(bgImage, OutputFormat.PNG);

String text = "123456";
combiner.addTextElement(text, "黑体", Font.BOLD, 60, 1800, 540);

//生成图片
combiner.combine();
String fileName = "Leader.png";
combiner.save(basePath + fileName);
