Can't call method "Convolve" on unblessed reference at gifaninmation.pl line 47.

I'm using cpanm trying to find a method that contains the function convolve
but I only found the method Imager.

https://metacpan.org/pod/Imager

When I try to declare the method and use it in the code, the result is
always wrong.

I am using the following libraries:

>
>
>
> *#!/usr/local/bin/perl use Image::Magick;use Imager;*
