php ImageMagick windows installation tutorial, phpimagemagick

1. Download ImageMagick

Open http://imagemagick.org/script/binary-releases.php#windows to download the latest version. The current version is ImageMagick-6.5.4-2-Q16-windows-dll.exe

The current static versions can run well on various platforms, but they are difficult to understand, so you should download a dynamic version. If your system/computer supports 16-bit color, then you should use the Q16 version (there is also an 8-bit version), the difference between the two will be explained below.

For myself, the latest version does not run well on my computer, so I use some older versions. ImageMagick-6.4.2-7-Q16-windows-dll is suitable for me. My computer is Windows XP SP2, 32 Bit, Intel Centrino 1.76GHZ, you can download these older versions here.

I suggest you use the latest version and follow the steps below. If it doesn't work properly, then switch back to the old version.

2. Install ImageMagick

Install IM in the directory below

Copy code The code is as follows:

C:imagemagick

There is no space in between. Do not install to c:program filesetc

Don’t forget to click the "Add to system path" button. You don’t need to worry about other selection buttons.

3. Test whether the installation is successful

Open the command line (run->"CMD"->Enter), enter convert and press Enter. You should be able to see the help content, if so you can go directly to step four.

If it prompts "convert is not an internal or external command, nor is it an operable program or batch file" or "Please enter the drive letter to convert" (convert is a default system command to convert FAT32 to NTFS) then You need to add the ImageMagick installation path to the system path yourself.

My Computer-> Right-click-> Properties-> Advanced-> Environment Variables-> System Variables-> Find "Path"-> Select and click to edit-> The installation path is added.

4. Download php_Imagick.dll

Due to version issues, if you use PHP 5.2.x please download the dll here where you will get your. dyn = dynamic, st = static, q16 = 16 bit, q8= 8 bit. Of course, this should match the version you downloaded. If you downloaded the q16 dynamic library, your corresponding file is php_imagick_dyn-Q16.dll

If you are using PHP 5.3.x, this is your location to download the version you need.

5. Place the dll into your extension folder

For ease of use, rename the DLL file you downloaded to php_imagick.dll and place it in your extensions folder, usually:

Copy code The code is as follows:

php/ext/

If not, then you can find the corresponding extension directory in your php.ini file.

Copy code The code is as follows:

Directory in which the loadable extensions (modules) reside.extension_dir = "Something something"

6. Edit PHP.ini

If the following sentence exists, just remove the comment. If it does not exist, add the following sentence yourself

Copy code The code is as follows:

extension=php_imagick.dll

7. Restart

Very important step, it took me about an hour to get it right, but. . . You need to restart your computer for it to take effect.

If you do not restart your computer but just restart your apache, you will see the error that this module cannot be loaded, so please be sure to restart your computer.

Copy code The code is as follows:

Unable to find CORE_RL_Wand.dll something something.

8. Start apache and check the corresponding settings

Start apache, check phpinfo(), if you see the imagick library and the corresponding value set, go directly to step nine.

If you can’t use it normally after installation, you can try changing a few DLLs first. If it still doesn’t work, you can try changing to an older version of ImageMagick. Anyway, don’t lose heart.

9. Test and see

Put a picture into the same directory as the test.php script and name it a.jpg. Run the script. If you can see the picture a_thumnail.jpg, then it is ok. Below is the script

Copy code The code is as follows:

$im = new imagick( 'a.jpg' );
// resize by 200 width and keep the ratio
$im->thumbnailImage(200, 0);
// write to disk
$im->writeImage( 'a_thumbnail.jpg' );
?>
