Laravel Call to undefined function Intervention\Image\Gd\imagecreatefrompng()
提问by Mamulasa
Hi I am using glide (http://glide.thephpleague.com/) for image manipulation in my laravelproject.
I am facing an issue when storing an Image.
"Call to undefined function Intervention\Image\Gd\imagecreatefrompng()"
嗨，我在我的项目中使用 glide ( http://glide.thephpleague.com/) 进行图像处理laravel。我在存储图像时遇到问题。“调用未定义的函数Intervention\Image\Gd\imagecreatefrompng()”
The strange thing is that I can open the image with "preview" on my mac. But not in the browser. Also Photoshop tells me that there is something wrong with this file, it's corrupt.
奇怪的是，我可以在我的 mac 上用“预览”打开图像。但不是在浏览器中。Photoshop 还告诉我这个文件有问题，它已损坏。
this is how I save the image in a private folder:
这就是我将图像保存在私人文件夹中的方式：
public function update(Request $request, $id)
{
//Show the image
echo '<img src="'.$_POST['img_val'].'" />';
//Get the base-64 string from data
$filteredData=substr($_POST['img_val'], strpos($_POST['img_val'], ",")+1);
//Decode the string
$unencodedData=base64_decode($filteredData);
//Save the image
$storagepath = storage_path('app/images/users/' . Auth::user()->id);
$imgoutput = File::put($storagepath.'/flyer.jpg', $unencodedData);
return view('backend.flyers.index')->withImgoutput($imgoutput);
//->withStoragepath($storagepath);
}
It seems like File::put(XXX.jpg) JPGcauses the problem. How can I fix this?
似乎 File::put( XXX.jpg) JPG导致了问题。我怎样才能解决这个问题？

This is because the GD Libraryis missing. Try this:
这是因为GD Library缺少。尝试这个：
You must enable the library GD2.
您必须启用库 GD2。
Find your (proper) php.inifile
找到你的（正确的）php.ini文件
Find the line: ;extension=php_gd2.dlland remove the semicolon in the front.
找到这一行：;extension=php_gd2.dll并去掉前面的分号。
The line should look like this:
该行应如下所示：
extension=php_gd2.dll
Then restart apache and you should be good to go.
然后重新启动apache，你应该很高兴。
