Très bon tuto sur la génération d'image (par exemple des miniatures) à partir de pdf avec php et imgick.

function join_paths() {
   $paths = array();

   foreach (func_get_args() as $arg) {
       if ($arg !== '') { $paths[] = $arg; }
   }

   return preg_replace('#/+#','/',join('/', $paths));
}

<?php

//Note that the function returns an Imagick object and does not modify the existing object. Below is my code for converting a PNG with transparency into a JPG with a background color. This code illustrates the difference.


$im = new Imagick('image.png');
$im->setImageBackgroundColor('white');

$im->flattenImages(); // This does not do anything.
$im = $im->flattenImages(); // Use this instead.

$im->setImageFormat('jpg');
$im->writeImage('image.jpg');

?>
