I'm trying to use Imager::GIF "a handy module for animated GIF processing" to scale images but get an error when trying to write:

Usage: i_writegif_wiol(IO,hashref, images...) at .../Imager/File/GIF.pm line 84.

The module has no real tests (just one: will it load) so it looks good to the Testers. I can see what it's trying to do and could cargo-cult it into my own code but I can't see what's wrong, can you?

https://metacpan.org/release/Imager-GIF/source/lib/Imager/GIF.pm https://metacpan.org/release/Imager-File-GIF/source/GIF.pm#L84 

#!/usr/bin/perl

use strict;
use warnings;
use Imager::GIF;

my $gif = shift || die 'need an image';
my $img = Imager::GIF->new;

$img->read(file => $gif)
or die $img->errstr;

$img = $img->scale(scalefactor => 0.5);

$img->write(file => join '.', $gif, 'half', 'gif')
or die $img->errstr;

Thanks for your attention to this matter.
