An ImageMagick "exec" component for PHP apps.


Install with Composer, it's the best packages manager you can have :

composer require orbitale/imagemagick-php


  • PHP 7.1 or higher
  • symfony/yaml 3.0 or higher
  • symfony/process 3.0 or higher
  • smyfony/filesystem 3.0 or higher
  • The exec() function must be available and work in order to communicate with ImageMagick executables.
  • ImageMagick has to be installed on your server, and the binaries must be executable by exec().


There are not many settings, but when you instanciate a new Command object, you may specify ImageMagick's executable directory directly in the constructor, for example :

use Orbitale\Component\ImageMagick\Command;

// Default directory for many Linux distributions:
$command = new Command('/usr/bin');

// Or in Windows, depending of the install directory:
$command = new Command('C:\ImageMagick');

// If it is available in the global scope for the user running the script:
$command = new Command();

The constructor will automatically search for the convert executable, test it, and throw an exception if it's not available.

/!\ Make sure your ImageMagick executables have the "+x" chmod option, and that the user has the rights to execute it.


Basic image converter with ImageMagick's basic logo

Read the comments :

require_once 'vendor/autoload.php'; // A classic one, if you know how Composer works.

use Orbitale\Component\ImageMagick\Command;

// Create a new command
$command = new Command();

$response = $command
    // The command will search for the "logo.png" file. If it does not exist, it will throw an exception.
    // If it does, it will create a new command with this source image.

    // The "file()" method will simply add a file name to the command.
    // For this one, it will be used as an output file name,
    //  that's why we set the 2nd argument "checkExistence" to "false",
    //  so the Command will not check if the file exists (because it would throw an exception then)
    ->file('logo.gif', false)

    // At this time, the command shall look like this :
    // $ "{ImageMagickPath}convert" "logo.png" "logo.gif"

    // Then we run the command by using "exec()" to get the CommandResponse

if (!$response->hasFailed()) {
    // If it has not failed, then we simply send it to the buffer
    header('Content-type: image/gif');
    echo file_get_contents('logo.gif');

Simply resizing an image

require_once 'vendor/autoload.php';

use Orbitale\Component\ImageMagick\Command;

// Create a new command
$command = new Command();

$response = $command

    // Here we are using "mogrify", so the file must exist as it is overwritten (it's basically the difference between "convert" and "mogrify")

    // The "resize" method allows you to add a "Geometry" operation.
    // It must fit to the "Geometry" parameters in the ImageMagick official documentation (see links below)


if (!$response->hasFailed()) {
    header('Content-type: image/jpeg');
    echo file_get_contents('background.jpeg');

Supported commands:

  • convert
  • mogrify
  • identify

Currently supported options:

There are TONS of command-line options, and each have its own validation system.

This is why a "few" ones are implemented now.

Note: If an option is not implemented in the Command class, you should create an issue or make a Pull Request that implements the new option!

Feel free to ask if you want more!

Some aliases that do magic for you:

  • Command::text(): This method uses multiple options added to the -annotate one to generate a text block. You must specify its position and size, but you can specify color and the font file used. See -annotate documentation.

  • Command::ellipse(): (check source code for the heavy prototype!) This method uses the -stroke, -fill and -draw property to create an ellipse/circle/disc on your picture. Note: I recommend to check both the source code and the documentation to be sure of what you are doing. See -draw documentation.
