UEditor编辑器上传图片是自动提取的,但是图片没有水印功能,下面小编和各位一起来看看。
UEditor编辑器没有上传图片加水印的功能,需要进行二次开发,本例是在PHPCMS系统中对百度编辑器进行二次开发,添加上传图片加水印功能。
首先打开UEditor编辑器文件目录的php文件夹,打开Uploader.class.php,把PHPCMS添加水印的方法复制过来,加到这个类所有成员方法最后面,然后进行修改如下:
//图片加水印public function watermark($source, $target = "", $w_pos = "", $w_img = "", $w_text = "99danji",$w_font = 8, $w_color = "#ff0000") {$this->w_img = "watermark.png";$this->w_pos = 9;$this->w_minwidth = 400;$this->w_minheight = 200;$this->w_quality = 80;$this->w_pct = 85; $w_pos = $w_pos ? $w_pos : $this->w_pos;$w_img = $w_img ? $w_img : $this->w_img;//if(!$this->watermark_enable || !$this->check($source)) return false;if(!$target) $target = $source;//$w_img = PHPCMS_PATH.$w_img;//define("WWW_PATH", dirname(dirname(dirname(__FILE__)));$w_img = "../../../images/water/".$w_img;$source_info = getimagesize($source);$source_w= $source_info[0];$source_h= $source_info[1];//if($source_w < $this->w_minwidth || $source_h < $this->w_minheight) return false;switch($source_info[2]) {case 1 :$source_img = imagecreatefromgif($source);break;case 2 :$source_img = imagecreatefromjpeg($source);break;case 3 :$source_img = imagecreatefrompng($source);break;default :return false;}if(!empty($w_img) && file_exists($w_img)) {$ifwaterimage = 1;$water_info= getimagesize($w_img);$width= $water_info[0];$height= $water_info[1];switch($water_info[2]) {case 1 :$water_img = imagecreatefromgif($w_img);break;case 2 :$water_img = imagecreatefromjpeg($w_img);break;case 3 :$water_img = imagecreatefrompng($w_img);break;default :return;}} else {$ifwaterimage = 0;$temp = imagettfbbox(ceil($w_font*2.5), 0, PC_PATH."libs/data/font/elephant.ttf", $w_text);$width = $temp[2] - $temp[6];$height = $temp[3] - $temp[7];unset($temp);}switch($w_pos) {case 1:$wx = 5;$wy = 5;break;case 2:$wx = ($source_w - $width) / 2;$wy = 0;break;case 3:$wx = $source_w - $width;$wy = 0;break;case 4:$wx = 0;$wy = ($source_h - $height) / 2;break;case 5:$wx = ($source_w - $width) / 2;$wy = ($source_h - $height) / 2;break;case 6:$wx = $source_w - $width; $wy = ($source_h - $height) / 2;break;case 7:$wx = 0;$wy = $source_h - $height;break;case 8:$wx = ($source_w - $width) / 2;$wy = $source_h - $height;break;case 9:$wx = $source_w - $width;$wy = $source_h - $height;break;case 10:$wx = rand(0,($source_w - $width));$wy = rand(0,($source_h - $height));break; default:$wx = rand(0,($source_w - $width));$wy = rand(0,($source_h - $height));break;}if($ifwaterimage) {if($water_info[2] == 3) {imagecopy($source_img, $water_img, $wx, $wy, 0, 0, $width, $height);} else {imagecopymerge($source_img, $water_img, $wx, $wy, 0, 0, $width, $height, $this->w_pct);}} else {if(!empty($w_color) && (strlen($w_color)==7)) {$r = hexdec(substr($w_color,1,2));$g = hexdec(substr($w_color,3,2));$b = hexdec(substr($w_color,5));} else {return;}imagestring($source_img,$w_font,$wx,$wy,$w_text,imagecolorallocate($source_img,$r,$g,$b));}switch($source_info[2]) {case 1 :imagegif($source_img, $target);break;case 2 :imagejpeg($source_img, $target, $this->w_quality);break;case 3 :imagepng($source_img, $target);break;default :return;} if(isset($water_info)) {unset($water_info);}if(isset($water_img)) {imagedestroy($water_img);}unset($source_info);imagedestroy($source_img);return true;} public function check($image) {return extension_loaded("gd") && preg_match("/.(jpg|jpeg|gif|png)/i", $image, $m) && file_exists($image) && function_exists("imagecreatefrom".($m[1] == "jpg" ? "jpeg" : $m[1]));}对比我修改的部分,由于phpcms水印可以在后台管理设置,phpcms自带的水印方法通过读取配置文件获取路径,和读取数据库设置获取参数设置,那么这些地方需要手动进行设置。
对了,在upFile方法还要添加一段函数:
复制代码 代码如下:
if ($this->watermark) {
$this->watermark($this->filePath,$this->filePath);
}
然后打开UEditor百度编辑器php目录下的action_upload.php文件,加上是否添加水印的参数:
/* 上传配置 */$base64 = "upload";switch (htmlspecialchars($_GET["action"])) {case "uploadimage":$config = array("pathFormat" => $CONFIG["imagePathFormat"],"maxSize" => $CONFIG["imageMaxSize"],"allowFiles" => $CONFIG["imageAllowFiles"]);$fieldName = $CONFIG["imageFieldName"];$watermark = true;break;然后在后面还有一句要改成:
复制代码 代码如下:
/* 生成上传实例对象并完成上传 */
$up = new Uploader($fieldName, $config, $base64, $watermark);
这样就大功告成了,本文主要是提供思路和参考。
以上所述就是本文的全部内容了,希望大家能够喜欢,能够对大家使用ue编辑器有所帮助。
