imagick 拓展的下载地址
- https://windows.php.net/downloads/pecl/releases/imagick/ 可惜的是这个地址最新版没有php7.2, 如果是7.1可以推荐
- https://windows.php.net/downloads/pecl/snaps/imagick/ 这个snaps 版本支持php7.2， 此时最新为3.4.3
当前服务器为nginx, API320170718,NTS,VC15， 故PHP使用NTS版本，由此下载拓展：
https://windows.php.net/downloads/pecl/snaps/imagick/3.4.3/php_imagick-3.4.3-7.2-nts-vc15-x86.zip
拓展安装

解压压缩包得到如下一大坨文件
$ ls php_imagick-3.4.3-7.2-ts-vc15-x64 ChangeLog CORE_RL_lqr_.pdb CORE_RL_zlib_.pdb CORE_RL_bzlib_.dll CORE_RL_MagickCore_.dll CREDITS CORE_RL_bzlib_.pdb CORE_RL_MagickCore_.pdb LICENSE CORE_RL_glib_.dll CORE_RL_MagickWand_.dll LICENSE.IMAGEMAGICK CORE_RL_glib_.pdb CORE_RL_MagickWand_.pdb php_imagick.dll CORE_RL_lcms_.dll CORE_RL_ttf_.dll php_imagick.pdb CORE_RL_lcms_.pdb CORE_RL_ttf_.pdb CORE_RL_lqr_.dll CORE_RL_zlib_.dll
需要做一个操作就是，删除非dll文件，因为没啥用
-
复制
php_imagick.dll到拓展的ext目录， 并在php.ini中添加相应的配置，其他的dll并没有什么作用 -
测试执行一下，结果显示如下
$ php --ri imagick imagick imagick module => enabled imagick module version => @[email protected] imagick classes => Imagick, ImagickDraw, ImagickPixel, ImagickPixelIterator, ImagickKernel Imagick compiled with ImageMagick version => ImageMagick 7.0.7-11 Q16 x64 2017-11-23 http://www.imagemagick.org Imagick using ImageMagick library version => ImageMagick 7.0.7-11 Q16 x64 2017-11-23 http://www.imagemagick.org ImageMagick copyright => Copyright (C) 1999-2015 ImageMagick Studio LLC ImageMagick release date => 2017-11-23 ImageMagick number of supported formats: => 0 Directive => Local Value => Master Value imagick.locale_fix => 0 => 0 imagick.skip_version_check => 0 => 0 imagick.progress_monitor => 0 => 0
//PHP 显示对应的报错 NoDecodeDelegateForThisImageFormat `PNG‘ @ error/constitute.c/ReadImage/509"
而且这时候，无论你怎么复制原本的dll都没效果。所以这个时候要了解到，只有原本的几个dll是什么用处都没有的。

下载对应的imagick文件，比如这里是vc15 x86的版本，正好官网有提供依赖，（实际上这条是错误的到道路），官网的依赖不能解决问题
https://windows.php.net/downloads/pecl/deps/ImageMagick-7.0.7-11-vc15-x86.zip
下载解压，并添加路径到PATH中，php正常运行无错误，但实际查看细节就发现，还是和上面一样

检查发现ImageMagick的版本为
7.0.7-11 Q16 x64, 实际上我只要去官网下载对应的版本即可。不一致的版本 https://www.imagemagick.org/download/binaries/ImageMagick-7.0.8-5-Q16-x86-dll.exe
安装Imagick, 同时添加ImageMagick-7.0.8-Q16modulescoders到系统Path中如果下载的版本不一致，执行时会出现一个警告，如下：但此时已经能正常运行，也可以看到
7.0.8-5 Q16 x86 2显示了出来$php --ri imagick PHP Warning: Version warning: Imagick was compiled against ImageMagick version 1799 but version 1800 is loaded.

正确的历史版本下载
http://ftp.icm.edu.pl/packages/ImageMagick/binaries/ImageMagick-7.0.7-11-Q16-x86-dll.exe
同样，这里可以找到许多历史版本下载，自己去处理即可，安装完毕后需要对应的将
ImageMagick-7.0.7-Q16添加到PATH中，和7.0.8有所差异，看起来是文件结构有所调整。
完成安装以后
- 对应的拓展PECL官网有下载，各个不同的版本目录多找找。
- 官网的依赖文件夹的数据Imagick压缩包并不能直接作为依赖源使用。
- Imagick使用了不同的版本可能能运行，但会有警告。
- 下载需要使用
-Q16-x64-dll.exe的安装版本，才有完整的数据。
