imagick image processor code, suggestion needed

[dominio]

Hi there,

 

we wanted to increase quality of images in our Prestashop installation so we created an override we put in

override/classes

 

imagemanager.php

 

 

it works very well an images are wonderful but we get error 500 in prstashop when we open some orders, I believe this is due to miniature images creation.

 

Is there someone among you that already have a better code to use imagick? Or can see through it to find errors?

 

Thank you in advance,

Cristian
