PHP中需要修改图片或者合成图片，需要的扩展就是imagick，这个是一个老牌扩展。安装需要依赖 ImageMagick这个软件。
安装ImageMagick
系统是：Cent OS8
yum config-manager --set-enabled PowerTools
yum install ImageMagick-devel
yum install ImageMagick
通过 ImageMagick的软件的 convert命令来查看安装版本和支持的图片格式
convert -version
[root@qidong ~]
# convert -version
Version: ImageMagick 6.9.10-86 Q16 x86_64 2020-01-13 https://imagemagick.org
Copyright: © 1999-2020 ImageMagick Studio LLC
License: https://imagemagick.org/script/license.php
Features: Cipher DPC Modules OpenMP(4.5)
Delegates (built-in): bzlib cairo fftw fontconfig freetype gslib gvc jbig jng jp2 jpeg lcms ltdl lzma openexr pangocairo png ps raqm raw rsvg tiff webp wmf x xml zlib注意～！安装完成后不要随便升级软件或者系统。会出现依赖版本比匹配的情况
举个例子：我的centos7安装后升级php7.1的版本用不了
imagick扩展的。下面的是我重新安装后的，少了一些类型支持。

服务器系统升级该用了龙蜥OS安装出现错误
package ImageMagick-6.9.12.77-1.el8.x86_64 requires libMagickCore-6.Q16.so.7()(64bit), but none of the providers can be installedxxxxxxxx
解决办法安装第三方库
后在执行安装
正常所需要Yum包
