php - How to install ImageMagick with Wampserver 3.0.0 64?

Question

I lost a day trying to figure this out, at various times getting "no decode delegate for this image format" and "The specified module could not be found" errors. The information I could find on these problems was dated in terms of version numbers, and many included instructions like overwriting the ImageMagick-installed dlls from the PECL distribution or copying dlls into windows/system32; two things I didn't want to do.

Environment: Windows 10
Wampserver: 3.0.0, Apache/2.4.17 (Win64) PHP/5.6.16

Answer 1

1. Downloaded and installed latest ImageMagick:
   ImageMagick-7.0.2-0-Q16-x64-dll.exe

2. Downloaded php_imagick-3.4.3rc1-5.6-ts-vc11-x64 from http://windows.php.net/downloads/pecl/releases/imagick/3.4.3rc1/

3. Unpacked php_imagick.dll into [wampserver directory]inphpphp5.6.16ext

4. Added extension=php_imagick.dll to
   [wampserver directory]inapacheapache2.4.17inphp.ini

5. Got "no decode delegate for this image format" error, but at least imagick showed up in phpinfo() where I could see that php_imagick.dll was compiled with ImageMagick 6.9.3-7 Q16 x64. There was no obvious way to know this beforehand.

6. Downloaded ImageMagick-6.9.3-7-Q16-x64-dll.exe from http://ftp.icm.edu.pl/packages/ImageMagick/binaries/ (ImageMagick has removed this package from their site).

7. Uninstalled ImageMagick-7.0.2-0-Q16-x64,
   installed ImageMagick-6.9.3-7-Q16-x64 to c:ImageMagick,
   added c:ImageMagick to PATH (in front, to avoid collision with windows convert.exe).

8. Verified everything ok with:

    $image = new Imagick();
    $image->readImage([path to my jpeg]);
   
    $wm = new Imagick();
    $wm->readImage([path to my watermark png]);
   
    $image->compositeImage($wm, imagick::COMPOSITE_OVER, 5, 5);
   
    header("Content-Type: image/jpeg");
    echo $image;
