简单JSP代码

图片加水银文字

try {        String path = request.getRealPath("images\\01.jpg");        out.print(path);        BufferedImage img = ImageIO.read(new FileInputStream(path));        out.print(img.getWidth());        out.print("
     
");        out.print(img.getHeight());        Graphics g = img.getGraphics();        g.setColor(Color.YELLOW);        g.drawString("Hello 13014577033", 100, 200);        ImageIO.write(img, "jpg", new File("c:/t_01.jpg"));    } catch (Exception e) {        e.printStackTrace();    }

 

加logo

String path = request.getRealPath("images\\02.jpg");    String npath = request.getRealPath("images\\s02.jpg");    ImageUtil iu = new ImageUtil(path);    iu.thumd(100,50,npath);    String nnpath = request.getRealPath("images\\t02.jpg");    iu.txt("培训教育",30, nnpath);    String logo = request.getRealPath("images\\fz.png");    String nn = request.getRealPath("images\\logot2.jpg");    iu.logo(logo, nn);

缩略图

try {    String path = request.getRealPath("images\\01.jpg");    BufferedImage img = ImageIO.read(new FileInputStream(path));    int w = img.getWidth();    int h = img.getHeight();     int ww = 200;    int hh = 150;    BufferedImage nimg = new BufferedImage(ww,hh,BufferedImage.TYPE_INT_RGB);    Graphics g = nimg.getGraphics();    g.drawImage(img, 0, 0, ww, hh, 0, 0, w, h, null);    ImageIO.write(nimg, "jpg", new File("c:/s_01.jpg"));} catch (Exception e) {    e.printStackTrace();}
