After 3 days and hours of frustration, here is the steps to follow for getting php_imagick working on Windows server running IIS:
- make sure everything you install is 32-bit – this is because PHP is 32-bit, and introducing any 64-bit component will break the whole thing
- download php_imagick here: http://windows.php.net/downloads/pecl/releases/imagick/3.1.2/php_imagick-3.1.2-5.3-nts-vc9-x86.zip
- place only the php_imagick.dll file in the “ext” subdirectory of PHP
- install a legacy version of ImageMagick – this is because as the forum thread http://stackoverflow.com/questions/8457744/installing-imagemagick-onto-xampp-windows-7 points out, PHP 5.3 is compiled with a different version of MSVC than the latest version of ImageMagick, and the two don’t talk to each other. Unfortunately, ImageMagick doesn’t keep archives of old versions, but thankfully other sites do: http://ftp.sunet.se/pub/multimedia/graphics/ImageMagick/binaries/ImageMagick-6.6.5-10-Q16-windows-dll.exe
For simplicity sake, install the file in “C:\ImageMagick”
- install a legacy version of GhostScript – again, this is to make sure the versions are compatible with each other. Again, Ghostscript themselves don’t seem to keep legacy files, but you can get them SourcrForge: http://sourceforge.net/projects/ghostscript/files/GPL%20Ghostscript/8.62/gs862w32.exe/download
For simplicity sake, install the file in “C:\Ghostscript”
- After all this, ImageMagick still won’t see Ghostscript as a delegate for handling PDF’s – you must edit the “config\delegates.xml” file and replace all instances of “@[email protected]” with the full path to the Ghostscript binary (note the forward slashes) as described http://stackoverflow.com/questions/13304832/ghostscripts-file-path-in-imagemagick: C:/Ghostscript/8.62/bin/gswin32c.exe
- At this stage, any command-line testing of the ImageMagick to Ghostscript communication will probably work – but it won’t work under IIS. This is because by default, Ghostscript uses “C:\Windows\Temp”, but IIS doesn’t have permission to that directory. You must grant read/write access to that directory to “IIS_IUSRS” (or php_imagick will keep reporting that there is no delegate) as explained here: http://www.wizards-toolkit.org/discourse-server/viewtopic.php?f=1&t=24757&p=110439&sid=35e443f4faf1b92d68632a72c4000d3e#p110439
- Finally – REBOOT! None of this will work without rebooting at least once so the entire OS has references to the newly installed software and libraries.
With any luck, you should now have a working php_imagick installed – you can confirm (at least part) of this using phpinfo() – although this may report php_imagick installed, it’s not a guarantee that PDF support will be working. You won’t know that part until you actually try to read in a PDF.
