使用readImage函数时出错(Imagick) [英] Error in using readImage function (Imagick)

问题描述

我具有使用Imagick扩展名更改Image DPI的功能:

I have this function to change Image DPI using Imagick extension:

    <?php
// create an image copy
$image=new Imagick("D:/xampp/htdocs/extra/1270006212-Z3BFN9J.jpg");
$image->readImage("D:/xampp/htdocs/extra/1270006212-Z3BFN9J.jpg");
$image->setImageFileName("D:/xampp/htdocs/extra/ANC.jpg");
$image->writeImage();
?>

只要在readImage函数中到达程序，浏览器就会停止运行并给我错误:

Whenever program reached in readImage function, browser stops running and give me error:

推荐答案

[您没有提到要在哪个平台上运行，但我会假设它是某种Windows的路径.]

[You don't mention what platform you're running on but I'll presume from the paths it's some kind of Windows.]

该代码还可以，但是在某些版本的Imagick上，Windows上的readImage()存在问题(请参见 http://valokuva.org/?page_id=50 上的线程(Imagick开发人员的博客)并在注释中指出Windows是不受支持的平台.

The code is OK but there are problems with readImage() on Windows with some versions of Imagick (see https://bugs.php.net/bug.php?id=59594) and there are also general problems when using versions of ImageMagick above 6.6.4.0 on Windows as it is compiled against VC10 and the other components use VC9 (http://stackoverflow.com/questions/8608426/imagick-crash-with-php-5-3). Read the thread on http://valokuva.org/?page_id=50 (the Imagick developer's blog) and note in the comments that Windows is an unsupported platform.

我得出的结论是，根本不可能在Windows 7 x64上运行Imagick，而是安装了在Oracle VirtualBox下运行的Ubuntu服务器来进行Imagick开发.一直很好.

I came to the conclusion that it wasn't possible to run Imagick on Windows 7 x64 at all and installed an Ubuntu server running under Oracle VirtualBox to do Imagick development. That's been working nicely.
