图片合成

合成两张大小一样的图片

//读取第一张图片

       File fileOne = new File(startPath);

       BufferedImage ImageOne = ImageIO.read(fileOne);

       

       int width = ImageOne.getWidth();//图片宽度

       int height = ImageOne.getHeight();//图片高度

       

       //从图片中读取RGB

       int[] ImageArrayOne = new int[width*height];

       ImageArrayOne = ImageOne.getRGB(0,0,width,height,ImageArrayOne,0,width);

       

       //对第二张图片做相同的处理

       File fileTwo = new File(endPath);

       BufferedImage ImageTwo = ImageIO.read(fileTwo);

       int widthTwo = ImageTwo.getWidth();//图片宽度

       int heightTwo = ImageTwo.getHeight();//图片高度

       

       int[] ImageArrayTwo = new int[widthTwo*heightTwo];

       ImageArrayTwo = ImageTwo.getRGB(0,0,widthTwo,heightTwo,ImageArrayTwo,0,widthTwo);

       //生成新图片

       BufferedImage imageNew = new BufferedImage(width+widthTwo,height,BufferedImage.TYPE_INT_RGB);

       imageNew.setRGB(0,0,width,height,ImageArrayOne,0,width);//设置左半部分的RGB

       imageNew.setRGB(width,0,widthTwo,heightTwo,ImageArrayTwo,0,widthTwo);//设置右半部分的RGB

 

//在图片上写字

Graphics g = imageNew.getGraphics();   

           Font font = new Font("微软黑体",Font.BOLD,50);   

           g.setFont(font);   

           g.setColor(Color.RED);

           g.drawString("区间名称:"+caplog.getQjmc()+"  距离:"+caplog.getQjjl()+"m  区间平均速度:"+caplog.getJgcs()+"km/h  限速值:"+caplog.getZdsd()+"km/h  区间超速百分比:"+csbfb, 100, height-100);

           g.drawString("区间入口:"+caplog.getQdlkmc()+"  时间:"+caplog.getQdsj()+"  区间出口:"+caplog.getZdlkmc()+"  时间:"+caplog.getZdsj(), 100, height-50);

       String newpicName = (sdf.format(new Date())) + ".jpg";

       //合成图片的存储位置

       String newPath = savePicPath + nowyear + "/" + nowmonth + "/"+newpicName;
