看到一些网站的图片都是左上和右下都有水印，于是就想到修改discuz生成水印的函数来实现，具体操作步骤如下：
先打开include/image.class.php,修改水印位置相关的内容：
switch($watermarkstatus) {
case 1:
$x = +5;
$y = +5;
break;
case 2:
$x = ($img_w - $logo_w) / 2;
$y = +5;
break;
case 3:
$x = $img_w - $logo_w - 5;
$y = +5;
break;
case 4:
$x = +5;
$y = ($img_h - $logo_h) / 2;
break;
case 5:
$x = ($img_w - $logo_w) / 2;
$y = ($img_h - $logo_h) / 2;
break;
case 6:
$x = $img_w - $logo_w;
$y = ($img_h - $logo_h) / 2;
break;
case 7:
$x = +5;
$y = $img_h - $logo_h - 5;
break;
case 8:
$x = ($img_w - $logo_w) / 2;
$y = $img_h - $logo_h - 5;
break;
case 9:
$x = $img_w - $logo_w - 5;
$y = $img_h - $logo_h - 5;
break;
case 10://10为左上+右下双水印，这里是新增的
$x1 = +5;
$y1 = +5;
$x2 = $img_w - $logo_w - 5;
$y2 = $img_h - $logo_h - 5;
break;
} |
还有
if($watermarktype == 1) { ($watermarkstatus==10){//判断是否是双水印 @imageCopy($dst_photo, $watermark_logo, $x1, $y1, 0, 0, $logo_w, $logo_h); @imageCopy($dst_photo, $watermark_logo, $x2, $y2, 0, 0, $logo_w, $logo_h); } else{ @imageCopy($dst_photo, $watermark_logo, $x, $y, 0, 0, $logo_w, $logo_h); } } |
最后打开admin/setting.inc.php找到showsetting(‘settings_attach_image_watermarkstatus’，后面增加一行：
<input class="radio" type="radio" name="settingsnew[watermarkstatus]" value="10" '.$checkwm[10].'> #10 双水印 |
这样就可以再后台附件设置里看到。
