php - Imagick on heroku - is it possible?

Question

I need to do some actions on jpeg images - Heroku's PHP GD does not allow that. I've read that it is possible with Imagick, so i rewritten the code, pushed it to heroku and...

PHP Fatal error: Class 'Imagick' not found in [...]

So am I doing something wrong(code works locally)?

$tlo = new Imagick();
$tlo->newImage(640, 480, new ImagickPixel('white'));
$tlo->setImageFormat('jpg');

Is there any way of working with jpg on heroku?

A simpler approach is to install ImageMagick using composer.json, as explained here: https://devcenter.heroku.com/articles/php-support#using-optional-extensions

You just need to include imagick in the require section and update composer:

{
    ...
    "require": {
         "ext-imagick": "*",
         ...
    }
}
