    如何怎么添加图片水印?ECSHOP教程网图解ecshop商品添加水印,ecshop文章添加水印教程。


    Kindeditor编辑器和百度编辑器上传图片自动添加水印方法


    1.给Ecshop编辑器Kindeditor图片上传添加水印功能:

    在kindeditor/php/upload_json.php中,有两处需要修改的地方。

    第一步,在文件末尾添加一个方法

    function imageWaterMark($groundImage, $waterPos=0, $waterImage=”, $alpha=80, $waterText=”, $textFont=9, $textColor=’#FF0000′){
    $isWaterImage = FALSE;
    $formatMsg = ‘不支持该图片格式!请使用GIF、JPG、PNG格式的图片。’;
    //读取水印文件
    if(!empty($waterImage) && file_exists($waterImage)){
    $isWaterImage = TRUE;
    $water_info = getimagesize($waterImage);
    $water_w = $water_info[0];//取得水印图片的宽
    $water_h = $water_info[1];//取得水印图片的高
    switch($water_info[2]){//取得水印图片的格式
    case 1:$water_im = imagecreatefromgif($waterImage);break;
    case 2:$water_im = imagecreatefromjpeg($waterImage);break;
    case 3:$water_im = imagecreatefrompng($waterImage);break;
    default:die($formatMsg);
    }
    }
    //读取背景图片
    if(!empty($groundImage) && file_exists($groundImage)){
    $ground_info = getimagesize($groundImage);
    $ground_w = $ground_info[0];//取得背景图片的宽
    $ground_h = $ground_info[1];//取得背景图片的高
    switch($ground_info[2]){//取得背景图片的格式
    case 1:$ground_im = imagecreatefromgif($groundImage);break;
    case 2:$ground_im = imagecreatefromjpeg($groundImage);break;
    case 3:$ground_im = imagecreatefrompng($groundImage);break;
    default:die($formatMsg);
    }
    }else{
    alert(“水印图片不存在!”);
    }
    //水印位置
    if($isWaterImage){//图片水印
    $w = $water_w;
    $h = $water_h;
    $label = “图片的”;
    }
    if(($ground_w<$w) || ($ground_h<$h)){
    echo “需要加水印的图片的长度或宽度比水印”.$label.”还小,无法生成水印!”;
    return; // ecshop119.com
    }
    switch($waterPos){
    case 0://随机
    $posX = rand(0,($ground_w – $w));
    $posY = rand(0,($ground_h – $h));
    break;
    case 1://1为顶端居左
    $posX = 0;
    $posY = 0;
    break;
    case 2://2为顶端居中
    $posX = ($ground_w – $w) / 2;
    $posY = 0;
    break;
    case 3://3为顶端居右
    $posX = $ground_w – $w;
    $posY = 0;
    break;
    case 4://4为中部居左
    $posX = 0;
    $posY = ($ground_h – $h) / 2;
    break;
    case 5://5为中部居中
    $posX = ($ground_w – $w) / 2;
    $posY = ($ground_h – $h) / 2;
    break;
    case 6://6为中部居右
    $posX = $ground_w – $w;
    $posY = ($ground_h – $h) / 2;
    break;
    case 7://7为底端居左
    $posX = 0;
    $posY = $ground_h – $h;
    break;
    case 8://8为底端居中
    $posX = ($ground_w – $w) / 2;
    $posY = $ground_h – $h;
    break;
    case 9://9为底端居右
    $posX = $ground_w – $w;
    $posY = $ground_h – $h;
    if(!$isWaterImage){
    $posY = $ground_h – $h-20;
    }
    break;
    default://随机
    $posX = rand(0,($ground_w – $w));
    $posY = rand(0,($ground_h – $h));
    break;
    }
    //设定图像的混色模式
    imagealphablending($ground_im, true);
    if($isWaterImage){//图片水印
    //imagecopy($ground_im, $water_im, $posX, $posY, 0, 0, $water_w,$water_h);//拷贝水印到目标文件
    //生成混合图像
    imagecopymerge($ground_im, $water_im, $posX, $posY, 0, 0, $water_w, $water_h, $alpha);
    } else {//文字水印
    if( !empty($textColor) && (strlen($textColor)==7)){
    $R = hexdec(substr($textColor,1,2));
    $G = hexdec(substr($textColor,3,2));
    $B = hexdec(substr($textColor,5));
    } else {
    die(“水印文字颜色格式不正确!”);
    }
    imagestring($ground_im, $textFont, $posX, $posY, $waterText, imagecolorallocate($ground_im, $R, $G, $B));
    }
    //生成水印后的图片
    @unlink($groundImage);
    switch($ground_info[2]){//取得背景图片的格式
    case 1:imagegif($ground_im,$groundImage);break;
    case 2:imagejpeg($ground_im,$groundImage,100);break;//注意这里的100,经测试,100是图片质量最佳的,但文件大小会增加很多,95的时候质量还不错,大小和原来的差不多。作者采用95的值。
    case 3:imagepng($ground_im,$groundImage);break;
    default:die($errorMsg);
    }
    //释放内存
    if(isset($water_info)) unset($water_info);
    if(isset($water_im)) imagedestroy($water_im);
    unset($ground_info);
    imagedestroy($ground_im);
    }

    第二步,找到$json = new Services_JSON();(这个文件中有两处,alert($msg)方法里的不用操作),在后面添加如下一段代码

    $water_mark = 1;//1为加水印, 其它为不加
    $water_pos = 9;//水印位置,10种状态【0为随机,1为顶端居左,2为顶端居中,3为顶端居右;4为中部居左,5为中部居中,6为中部居右;7为底端居左,8为底端居中,9为底端居】
    $water_img = $_SERVER[‘DOCUMENT_ROOT’].’/images/water.gif’;//水印图片,默认填写空,请将图片上传至网站根目录的images下,例: water.gif
    $water_alpha = 50;//水印透明度
    $water_text = ”;//水印字符串,默认填写空;
    //$water_fontfile = $_SERVER[‘DOCUMENT_ROOT’] .’/upfiles/fonts/arial.ttf’;//文字水印使用的字体;
    if($water_mark == 1){
    imageWaterMark($file_path, $water_pos, $water_img, $water_alpha, $water_text);
    }

    这里只需要上传一张水印图片即可。

    完成上述操作后,在用Kindeditor编辑器上传图片就可以实现上图的效果了。


    2.ecshop百度编辑器添加水印功能


    打开includes/ueditor/php/imageUp.php文件,添加如下代码


    //添加水印,载入水印需要的文件 @author ECShop.Cx start
    define('IN_ECS', true);
    define('INIT_NO_USERS', true);
    require_once( '../../init.php');
    require_once( '../../cls_image.php');
    $image = new cls_image();
    if (intval($_CFG['watermark_place']) > 0 && !empty($_CFG['watermark']))
    {
    $image->add_watermark($tmpName , '', '../../'.$_CFG['watermark'], $_CFG['watermark_place'], $_CFG['watermark_alpha']);
    }
    //添加水印,载入水印需要的文件
