Question

Installing Image Magic in Windows 7: instructions I carried out these instructions.

1. Download and install ImageMagick-6.5.8-7 Q16-windows-dll.exe  ImageMagick-6.5.8-7-Q16-windows-dll.exe

2. Download php_imagick_dyn-Q16.dll imagick-windows-builds/080709/

   copy dll to [PHP]/extension dir and rename it to php_imagick.dll

3. You have to edit your php.ini file and add a new  extension.

   extension=php_imagick.dll
   

4. Save ini file and restart the apache server.

   (If necessary, restart your windows)

5. phpinfo() should show imagick enabled.

Then I try running a test script, but it doesn't work. It displays a missing Imagic class error.

Fatal error: Class 'Imagick' not found in C:...\imgborder.php on line XXX

Can someone please help me to install Imagick?
