Using setSize before reading an image file tells ImageMagick to resize the image immediately on load - this can give a substantial increase in performance time and save memory and disk resources for large images:

<?php

$image
= new Imagick();
$image->setSize(800,600);
$image->readImage($file);

?>

This might also save you having to call thumbnailImage to resize the image.

On my server, this only made a difference with jpgs - pngs and gifs were loaded at full size which took much longer (30s or more compared to 6s for a similar sized jpg).

This function is not working for me at all.
I am trying to generate Images from a PDF and this function does literally NOTHING, even it returns 'true'.....
