为什么这里一定要说 windows 系统是64位呢，因为如果是系统是64位，那么PHP5.5 一般都会选择64的， Imagemagick 组件也会选择64位的， 但是操蛋的是 64位的Imagemagick 组件，怎么弄都失败。 所以没有办法：php 和 Imagemagick 都换成32位的，一试 就OK 了。
国外网站，也有多个网站反馈 64位的Imagemagick不行
PHP 5.5:
http://windows.php.net/downloads/releas ... 11-x86.zip 这个版本没有了，我用的是 php-5.5.30-nts-Win32-VC11-x86.zip 这个版本
Imagemagick:

You got Windows (x32 o x64) and IIS. You want PHP 5.5 and Imagemagick.
!! : Everything (PHP, Imagemagick installation, php_imagick.dll) needs to be x86 (32bit) for now (x64 builds are still experimental).
Tested and working:
Windows: 2008R2 x64 SP1
Visual C++ 2012 redist x86 and x64: http://www.microsoft.com/en-us/download ... x?id=30679 ---这个我没有安装，因为我电脑已经安装了Visual C++ 2012 开发环境了。
PHP 5.5:
5.5.8 VC11 x86 Non Thread Safe (2014-Jan-09 18:16:08) ... all php5.5.x x86 nts should work ...
http://windows.php.net/downloads/releas ... 11-x86.zip
Imagemagick:
ImageMagick-6.8.4-0 Q16 x86 dll (you can try newer 6.8.4.x versions, but allways -x86-dll) ... install to c:\imagemagick and during install check "add to system path" ...
http://ftp.sunet.se/pub/multimedia/grap ... 86-dll.exe
php_imagick.dll :

---3.1.2的 imagick 不支持png，其实文档已经说的很明白了....
