論壇圖片浮水印完整版

[貝斯特]

圖片水印完整版本. joey http://coolvbb.info http://trueme.cn

感謝網友忘憂提供思路.

修改共2步.補充一步.

第一步:

打開functions_image.php 在最後加如下函數代碼:

//watermark images

function watermark_image($filepath,$id)

{

global $DB_site;

$wmark = "您的水印圖片路徑/圖片名稱.png";

$im = imagecreatefromjpeg($filepath);

imagealphablending($im, true);

$watermark = imagecreatefrompng($wmark);

$y = imagesy($im) - imagesy($watermark);

$w = imagesx($watermark);

$h = imagesy($watermark);

imagecopy($im, $watermark, 0, $y, 0, 0, $w, $h);

imagejpeg($im,$filepath ,100);
$filesize=filesize($filepath);

$DB_site->query("UPDATE " . TABLE_PREFIX . "attachment SET filesize='$filesize' WHERE attachmentid='$id'");

}

#####如果不想使用png圖片請使用如下函數(網友忘憂所寫)#####

//watermark images

function watermark_image($filepath,$id,$type)

{

global $DB_site;

$typ_img=getimagesize($filepath);

if( $typ_img[2] != 2 )

return '';

$font = "/u/home/bbs/images/simhei.ttf";

$font1 = "/u/home/bbs/images/arial.ttf";

$im = imagecreatefromjpeg($filepath);

imagealphablending($im, true);

$y = imagesy($im)-5;

$str_copyright=chr(0xE9).chr(0x9D).chr(0x92).chr(0xE6).chr(0xB5).chr(0xB7).c

hr(0xE7).chr(0xBB).chr(0xBC).chr(0xE5).chr(0x90).chr(0x88).chr(0xE4).chr(0xBF).c

hr(0xA1).chr(0xE6).chr(0x81).chr(0xAF).chr(0xE7).chr(0xBD).chr(0x91).chr(0x0D).c

hr(0x0D);



$white = ImageColorAllocate($im, 255, 255, 255);

$red = imagecolorallocate($im, 255, 0, 0);

imagettftext($im,11,0,15,$y+1,$red,$font,$str_copyright);

imagettftext($im,11,0,15,$y,$white,$font,$str_copyright);

imagettftext($im,11,0,130,$y+1,$red,$font1,"http://你的網站網址/");

imagettftext($im,11,0,130,$y,$white,$font1,"http://你的網站網址/");

imagejpeg($im,$filepath ,100);

$filesize=filesize($filepath);

switch($type)

{

case "thumb":

$SQL="UPDATE attachment SET thumbnail_filesize='$filesize' WHERE a

ttachmentid='$id'";

break;

case "attach":

$SQL="UPDATE attachment SET filesize='$filesize' WHERE attachmenti

d='$id'";

break;

}

$DB_site->query($SQL);

}


第2步:

打開functions_file.php

查找:

else if (!empty($thumbnail['filedata']))
{
// write out thumbnail now
$filename = fetch_attachment_path($posterid, $attachmentid, true);
$fp = fopen($filename, 'wb');
fwrite($fp, $thumbnail['filedata']);
fclose($fp);
unset($thumbnail);



後面加:
/* 水印 joey*/
if($extension=='jpg' or $extension=='jpeg' or $extension=='jpe')

{
watermark_image(fetch_attachment_path($posterid,$attachmentid),$attachmentid);
}

##############添加水印完成###########

如果你有現成的附件也想加上水印請按如下步奏再做處理:

打開admincp/misc.php

查找:

echo construct_phrase($vbphrase['processing_x'], "$vbphrase[attachment] : " .
construct_link_code($attachment['attachmentid'], "../attachment.php?$session[sessionurl]attachmentid=$attachment[attachmentid]", 1) . " ($vbphrase[post] : " .
construct_link_code($attachment['postid'], "../showthread.php?$session[sessionurl]postid=$attachment[postid]", 1) . " )") . ' ';


後面加上:

watermark_image(fetch_attachment_path($attachment['userid'],$attachment['attachmentid']),$attachment['attachmentid']);
echo"---本附件加水印完成---";



然後再重新建立縮略圖.

最後再刪去此改動,以免重複加水印.
