Thinkphp 3.1. 3 ueditor 1.4.3 添加水印

1.引入Ueditor 

     <!-- 实例化编辑器 -->
     <script type="text/javascript">
         window.UEDITOR_HOME_URL ="/Data/ueditor/";
         window.onload=function(){
             window.UEDITOR_CONFIG.initialFrameHeight=300;　　　　
             //window.UEDITOR_CONFIG.initialFrameWidth=1000;
             UE.getEditor('content');
         }
     </script>
     <!-- 配置文件 -->
     <script type="text/javascript" charset="utf-8" src="/Data/ueditor/ueditor.config.js"></script>
     <!-- 编辑器源码文件 -->
     <script type="text/javascript" charset="utf-8" src="/Data/ueditor/ueditor.all.js"> </script>

2.加入水印处理类 (随便找了一个)

 <?php
 /**
  * 加水印类，支持文字图片水印的透明度设置、水印图片背景透明。
  * 日期：2011-09-27
  * 作者：www.jb51.net
  * 使用：
  * $obj = new WaterMask($imgFileName); //实例化对象
  * $obj->$waterType = 1; //类型：0为文字水印、1为图片水印
  * $obj->$transparent = 45; //水印透明度
  * $obj->$waterStr = 'www.jb51.net'; //水印文字
  * $obj->$fontSize = 16; //文字字体大小
  * $obj->$fontColor = array(255,0255); //水印文字颜色（RGB）
  * $obj->$fontFile = = 'AHGBold.ttf'; //字体文件
  * $obj->output(); //输出水印图片文件覆盖到输入的图片文件
  */

     private function waterstr() {
         $rect = imagettfbbox($this->fontSize, 0, $this->fontFile, $this->waterStr);
         $w = abs($rect[2] - $rect[6]);

         imagesavealpha($this->water_im, true);
         $white_alpha = imagecolorallocatealpha($this->water_im, 255, 255, 255, 127);

     function output() {
         $this->imginfo();
         if ($this->waterType == 0) {
             $this->waterstr();
         } else {
             $this->waterimginfo();
             $this->waterimg();
         }
         switch ($this->srcImg_info[2]) {

             default:
                 die('添加水印失败！');
                 break;
         }
         imagedestroy($this->im);
         imagedestroy($this->water_im);
     }
 }
 ?>

3.在项目的Applacation 中添加config.json 文件 进行对添加水印配置:

 /* 前后端通信相关的配置,注释只允许使用多行方式 */
 {
     "waterType":1,/*类型：0为文字水印、1为图片水印*/
     "waterImg":"http://127.0.0.8/data/Logo/Logo.png",/*水印图片*/
     "waterStr":"www.smartop.xyz",/*水印文字*/
     "fontSize":16,/*文字字体大小*/
     "fontColor":[0,0,0],/*水印文字颜色（RGB）*/
     "fontFile":"./../../Font/ebrimabd.ttf",/*字体文件*/
     "transparent":45,/*水印透明度*/
     "pos":7,/*水印位置支持 1 2 3 4 5 6 7 8 9  九宫格*/
     "imagePathFormat": "/upload/{yyyy}{mm}{dd}/{time}{rand:6}" /* 上传保存路径,可以自定义保存路径和文件名格式 */
                                 /* {filename} 会替换成原文件名,配置这项需要注意中文乱码问题 */
                                 /* {rand:6} 会替换成随机数,后面的数字是随机数的位数 */
                                 /* {time} 会替换成时间戳 */
                                 /* {yyyy} 会替换成四位年份 */
                                 /* {yy} 会替换成两位年份 */
                                 /* {mm} 会替换成两位月份 */
                                 /* {dd} 会替换成两位日期 */
                                 /* {hh} 会替换成两位小时 */
                                 /* {ii} 会替换成两位分钟 */
                                 /* {ss} 会替换成两位秒 */
                                 /* 非法字符 \ : * ? " < > | */
                                 /* 具请体看线上文档: fex.baidu.com/ueditor/#use-format_upload_filename */
 }

4.修改controller.php入口文件

将自己的config.json自己的配置加入到配置里面

 $CONFIG = json_decode(preg_replace("/\/\*[\s\S]+?\*\//", "", file_get_contents("config.json")), true);
 $SELFCONFIG = json_decode(preg_replace("/\/\*[\s\S]+?\*\//", "", file_get_contents("./../../../../Application/Conf/config.json")), true);
 $CONFIG =  array_merge($CONFIG,$SELFCONFIG);

5.配置:action_upload.php 将自定义配置项写入：

             "waterType" => $CONFIG['waterType'],
             "waterImg" => $CONFIG['waterImg'],
             "waterStr" => $CONFIG['waterStr'],
             "fontSize" => $CONFIG['fontSize'],
             "fontColor" => $CONFIG['fontColor'],
             "fontFile" => $CONFIG['fontFile'],
             "transparent" => $CONFIG['transparent'],
             "pos" => $CONFIG['pos'],

6.配置:Uploader.class.php 增加一个水印处理的私有方法:

     /**
      * 添加水印
      */
     private function water(){
         require_once('Water.class.php');
         $obj = new WaterMask($this->filePath); //实例化对象
         if($this->config['waterType']){
             $obj->waterType = $this->config['waterType'];
             $obj->waterImg = $this->config['waterImg']; //水印图片
         }else{
             $obj->waterType = $this->config['waterType'];
             $obj->waterStr = $this->config['waterStr'];//水印文字
             $obj->fontSize = $this->config['fontSize']; //文字字体大小
             $obj->fontColor = $this->config['fontColor']; //水印文字颜色（RGB）
             $obj->fontFile = $this->config['fontFile']; //字体文件
         }
         $obj->transparent = $this->config['transparent']; //水印透明度
         $obj->pos = $this->config['pos']; //水印位置
         $obj->output(); //输出水印图片文件覆盖到输入的图片文件
     }
