Question

对于我的页面，我希望用户能够添加图像并自动为图像添加水印。我的代码：

//upload the image 
$this->image_lib->clear();

$this->load->library('image_lib');
$configthumb['image_library'] = 'gd2';

//create the watermark
$configthumb['source_image']    = $_SERVER['DOCUMENT_ROOT'].'/assets/img/design/full/'.$filename;
$configthumb['wm_type'] = 'overlay';
$configthumb['wm_overlay_path'] = './assets/img/watermark/watermark.png';
$configthumb['wm_opacity'] = 50;
$this->image_lib->initialize($configthumb); 

if ( ! $this->image_lib->watermark())
{
    echo $configthumb['source_image'];
    echo $this->image_lib->display_errors();
    echo     "error occured";
}
    echo $configthumb['source_image'];

如果我运行它，我得到：

严重程度：警告消息：imagecopymerge（）期望参数9为long，给定字符串文件名：libraries / Image_lib.php 行号：954

但它没有运行回声＆＃34;错误发生＆＃34 ;;

我检查了img Image_lib.php 954，它说：

imagecopymerge($src_img, $wm_img, $x_axis, $y_axis, 0, 0, $wm_width, $wm_height, $this->wm_opacity);

所以我检查了wm_opicty的值是什么，它是50

有人可以帮我解决这个错误吗？我也更改了$ config [＆＃39; wm_opacity＆＃39;] = 50;至＆＃34; 50＆＃34;并尝试完全删除该行，但我仍然得到相同的错误。
