discuz5.0水印【logo + 文字(英文/汉字任意选择)+发布者名字+时间】
[size=4][color=Red]我说的是ttf字体,好多人都问坐标怎么确定,那么我告诉大家,$text_x,$text_y所表示的坐标定义了第一个字符的基本点,大概是字符的左下角坐标。(其中$text_y 坐标,它设定了字体基线的位置,不是字符的最底端。)[/color][/size]
看到好多人都需要一些特别的水印,就做了这个特别为5.0做的水印.
修改文件bbs/admin/setting中的
[code]showsetting('settings_watermarkstatus', '', '', '<table cellspacing="'.INNERBORDERWIDTH.'" cellpadding="'.TABLESPACE.'" class="tableborder" style="margin-bottom: 3px; margin-top:3px;"><tr><td colspan="3"><input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="0" '.$checkwm[0].'>'.$lang['settings_watermarkstatus_none'].'</td></tr><tr align="center" class="altbg2"><td><input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="1" '.$checkwm[1].'> #1</td><td><input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="2" '.$checkwm[2].'> #2</td><td><input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="3" '.$checkwm[3].'> #3</td></tr><tr align="center" class="altbg2"><td><input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="4" '.$checkwm[4].'> #4</td><td><input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="5" '.$checkwm[5].'> #5</td><td><input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="6" '.$checkwm[6].'> #6</td></tr><tr align="center" class="altbg2"><td><input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="7" '.$checkwm[7].'> #7</td><td><input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="8" '.$checkwm[8].'> #8</td><td><input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="9" '.$checkwm[9].'> #9</td></tr></table>');[/code]

看到好多人都要汉字支持,所以添加了汉字支持[size=4],[color=Red]注意:以下修改只供discuz论坛的爱好者测试和研究,因为以下修改而出现的其他问题,本作者不负任何责任,因为牵涉到GBK汉字转utf编码,我测试没有出现问题,不保证不会出现其他问题,作者注!![/color][/size]
汉字支持修改以下(第一步修改文件bbs/admin/setting和上面的一样)主要是修改post.func.php文件:
[quote]首先添加附件到include目录下,所用到[color=Blue]的'simsun.ttc'[/color]为宋体字体,请到[color=Red]c:\windows\fonts[/color]下面找到宋体,复制到include即可,太大了没有办法上传![/quote]
在post.func.php文件找到下面
[code]if(!defined('IN_DISCUZ')) {
exit('Access Denied');
}[/code]
下面添加函数
[code]
//该函数是从网上找到,归原作者所有,我只是修改适合这里使用--独自流浪
function GBKToUnicode(&$String)
{
$UnicodeData=file(DISCUZ_ROOT."./include/gbkunicode.data");
$ReturnString="";
$StringLength=strlen($String);
$p="";
$q="";
for($i=0;$i<$StringLength;$i++){
if(($p=ord(substr($String,$i,1)))>128){
$q=ord(substr($String,++$i,1));
if ($p>254) {
$ReturnString.='&#'.hexdec('003f').';';
}
elseif ($q<64||$q>254) {
$ReturnString.='&#'.hexdec('003f').';';
}
else {
$q=($q-64)*4;
$ReturnString.='&#'.hexdec(substr($UnicodeData[$p-128],$q,4)).';';
}
}
else {
if ($p==128) {
$ReturnString.='&#'.hexdec('20ac').';';
}
else {
$ReturnString.='&#'.$p.';';
}
}
}
return $ReturnString;
}
[/code]

所用到[color=Blue]的'simsun.ttc'[/color]为宋体字体,请到[color=Red]c:\windows\fonts[/color]下面找到宋体,复制到include即可,太大了没有办法上传!
效果如下: 这东西不错,有空下回去测试! 会不会耗很多的服务器资源啊? 需要6.0的 嗯嗯.希望有6.0的:hug: 6.0的…………………………………… :Q :Q :Q 偶要慢慢看看.. 支持一下.............
