<?php /* * 名称:PHP单页面图片批量上传管理系统 by zozi * 功能:批量上传图片,自动读取目录,批量删除图片,自动获得图片地址, * 生成复制连接,支持图片水印 (水印支持图片或文字) * 水印参数: * $groundImage 背景图片,即需要加水印的图片,暂只支持GIF,JPG,PNG格式; * $waterPos 水印位置,有10种状态,0为随机位置; * 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为底端居右; * $waterImage 图片水印,即作为水印的图片,暂只支持GIF,JPG,PNG格式; * $waterText 文字水印,即把文字作为为水印,支持ASCII码,不支持中文; * $textFont 文字大小,值为1、2、3、4或5,默认为5; * $textColor 文字颜色,值为十六进制颜色值,默认为#FF0000(红色); * * 注意:Support GD 2.0,Support FreeType、GIF Read、GIF Create、JPG 、PNG * $waterImage 和 $waterText 最好不要同时使用,选其中之一即可,优先使用 $waterImage。 * 当$waterImage有效时,参数$waterString、$stringFont、$stringColor均不生效。 * 加水印后的图片的文件名和 $groundImage 一样。 */ ?> <?php $zpass='123456'; //登陆密码 $zurl='www.mycodes.net'; //使用地址 $zname='upimage.php'; //本页面名称 function imageWaterMark($groundImage,$waterPos=0,$waterImage="",$waterText="",$textFont=5,$textColor="#FF0000") { $isWaterImage = FALSE; $formatMsg = "暂不支持该文件格式,请用图片处理软件将图片转换为GIF、JPG、PNG格式。"; //读取水印文件 if(!empty($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($formatMsg); } } else { die("需要加水印的图片不存在!"); } //水印位置 if($isWaterImage)//图片水印 { $w = $water_w; $h = $water_h; $label = "图片的"; } else//文字水印 { $temp = imagettfbbox(ceil($textFont*2.5),0,"./cour.ttf",$waterText);//取得使用 TrueType 字体的文本的范围 $w = $temp[2] - $temp[6]; $h = $temp[3] - $temp[7]; unset($temp); $label = "文字区域"; } if( ($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; } 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-6; $posY = $ground_h - $h-6; 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 } 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,$groundImage);break; case 3:imagepng($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); } ?> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=gb2312" /> <title>图片上传</title> <style type="text/css"> <!-- body, table { font-family: "宋体"; font-size: 14px; padding:0px; margin:0px; } --> </style> </head> <body> <table width="760" border="0" align="center"> <tr> <td> <?php //当前时间 $nowtime=time(); $baseurl= $_SERVER['PHP_SELF'] ?
