Question

尝试创建缩略图，但我遇到了一些错误，而且我没有使用Imagick的经验。

这是我的PHP：

<?php
try {
    $imagick = new Imagick();
    $imagick->readImage('C:\xampp\htdocs\ppa\032.JPG');
    $imagick->thumbnailImage(800, 800);
    $imagick->writeImage('032(2).JPG');
}
catch(Exception $e) {
    die('Error when creating a thumbnail: ' . $e->getMessage());
}
?>

然后我收到此错误代码：

创建缩略图时出错：NoDecodeDelegateForThisImageFormat `C：\ XAMPP \ htdocs中\ PPA \ 032.JPG＆＃39; @ error / construct.c / ReadImage / 555

以下是我使用某些代码生成的一些信息，我无法再找到这些信息......：/

修改

1. I get the error instantly, there is no delay at all.
2. Running commands directly from CMD works on the examples given from installation instructions. 

I have just copied the wizard.jpg from the ImageMagick folder to use in the above script instead, just incase there is a problem with my image, but I get the same error.

代码运行：

<?php
print_r(Imagick::queryFormats());
?>

结果：

Array（）

编辑5 我使用他们网站（32位）的普通安装程序安装了Imagick，然后我终于找到了一个可以工作的dll，因为在ImageMagick的DLL网站上似乎没有可靠的下载部分＆＃ 39; S。

这是phpinfo（）显示有关Imagick的内容。 enter image description here

编辑6 我已经阅读了以下网站，这是它建议做什么，以及我做了什么。

如果您下载了DLL，请确保使用与Apache和PHP相同版本的Visual Studio进行编译（可能是VC11 for PHP 5.5）
根据您的设置下载线程安全或无线程安全
将DLL复制到扩展文件夹
在php.ini
下载并安装ImageMagick，确保选择动态链接库附带的版本，同时确保它是与PHP和Apache（32/64位）相同的平台构建的，即使你有64位系统，像我一样你可能会运行32位版本的PHP和Apache
将ImageMagick路径添加到系统PATH变量中，安装程序可以为您执行此操作，但请在“高级系统设置”中进行检查以确保它在那里
重启Apache
检查php_info（）以查看扩展程序已启用且支持某些图像格式

我的结果 1.下载：ImageMagick-6.8.8-9-Q16-x86-dll.exe - 找到安装目录中包含的dll文件，该文件名为＆＃34; php_imagick.dll＆＃34;并将其放入C：/ xampp / php / ext /

这导致以下错误： httpd.exe - 找不到入口点 程序入口点MagickGetImageAttribute不可能位于动态链接库CORE_RL_wand_.dll。

这个错误也是： PHP启动：无法加载动态库＆＃39; C：\ xampp \ php \ ext \ php_imagick.dll＆＃39; - 找不到指定的程序。 2.不适用 3.复制到C：/ xampp / php / ext / 4.启用扩展名：extension = php_imagick.dll 5.再次下载此版本（我有32位PHP）：ImageMagick-6.8.8-9-Q16-x86-dll.exe（Win32动态，每像素16位） 6. enter image description here

如上所述，我现在得到错误，之前没有错，但可能是错误的dll。

刚试过以下内容，但我得到了同样的错误：延长= C：/ImageMagick/php_imagick.dll

ImageMagick安装在C：/ ImageMagick中。

ANSWER

似乎我可能在我的PHP和Apache版本中使用了错误的dll版本。我下载了以下文件，并将扩展链接更改为ImageMagick的安装文件夹，而不是移动php文件夹的dll。

ImageMagick-6.6.5-10-Q8-windows-dll.exe

PHP 5.5.9。

Apache 2.4.7。

Answer 1

问题已经过时了，但由于现在这个问题似乎有点难以解决，我在这里发布了一个快速解决方案：

如果您使用的是Windows，则可以找到here包含ImageMagick DLL的存储库。

在php_imagick.dll文件夹

中成功加载/php/ext/扩展程序后

打印phpinfo()页面并观看下面报告的相应ImageMagick版本 ＆＃39;想象使用ImageMagick库版本＆＃39; 标签
然后下载该版本ImageMagick的邮政编码。最新的TS-VC11-x86 稳定版本：
php_imagick v3.4.1＆gt; ImageMagick-6.9.3-7-vc11-x86.zip
最后，提取下载的zip，转到其bin文件夹，将所有IM_MOD_RL_...dll个文件和FILTER_...dll文件复制到/apache/bin/文件夹，然后重新启动服务器，完成！
无需运行安装程序或更改环境变量等。

Answer 2

我认为您的基础Image Magick库的版本正在运行，但不支持您尝试打开的图像格式。您应该能够通过运行来测试它：

identify -list format

查看是否列出了JPEG 2000或JP2。

编辑

OP更新了Image Magick列出的图像格式列表，它似乎是一个完整的格式列表。但是，在PHP中运行Imagick::queryFormats()表示不支持图像格式。

当您使用的Image Image Magick版本不是安装的PHP版本的正确版本时，这显然是一个常见问题。 Imagick声称可以正确加载，但是没有可用于加载或保存图像的图像格式。

Answer 3

似乎我可能在我的PHP和Apache版本中使用了错误的dll版本。我下载了以下文件，并将扩展链接更改为ImageMagick的安装文件夹，而不是移动php文件夹的dll。

ImageMagick-6.6.5-10-Q8-windows-dll.exe

PHP 5.5.9。

Apache 2.4.7。

Answer 4

即使在安装GhostScript之后，我们也无法在从AWS切换到Azure后获得imagick代码，从而获得Delegate错误。我们最终将PHP代码转换为Image Magick命令行，使用函数execInBackground运行命令（PHP.net Exec() Page）

注意：命令行无法单独使用exec 。 php脚本不会正常终止。

//from PHP.net 
function execInBackground($cmd) { 
    if (substr(php_uname(), 0, 7) == "Windows"){ 
        pclose(popen("start /B ". $cmd, "r"));  
    } 
    else { 
        exec($cmd . " > /dev/null &");   
    } 
}

//create a thumbnail from the first page of PDF
//old php code
/*
$image_magick = new imagick(); 
$image_magick->setbackgroundcolor('white');
$image_magick->readImage($file_path . "[0]");
$image_magick = $image_magick->flattenImages();
$image_magick->setResolution(300,300);
$image_magick->thumbnailImage(102, 102, true);
$image_magick->setImageFormat('jpg');
$image_magick->writeImage($thumbnail_path);
*/

//command line syntax
$cmd = "magick convert " . chr(34) . $file_path . "[0]" . chr(34) . " -background white -flatten -resample " . chr(34) . "300x300" . chr(34) . " -thumbnail " . chr(34) . "102x102" . chr(34) . " -format jpg -write " . chr(34) . $thumbnail_path . chr(34);
execInBackground($cmd);

Imagick没有加载图像，带有'NoDecodeDelegateForThisImageFormat'错误消息
