You can also use Imager, which is far more easier to install than ImageMagick, has most of the features you will use 90% of the time, and is also easier to use, IMO.

The scale() method allows you to resize image with a maximum height or width. Or if it is not exactly what you want to do, you can still do maths with the getheight() and getwidth() methods.

#!/usr/bin/perl -w
use strict;
use Imager;

my $image = Imager->new;

# Load the original image
$image->open(file => $ARGV[0])
    or die $image->errstr;

# Get the dimensions of the picture
print "Size: ", $image->getwidth, 'x', $image->getheight, "\n";

# Scale the picture to at most 150px in width or height
my $resized = $image->scale( width => 150, height => 150, type => 'min
+' );

# Save the resized picture to disk
$resized->write(file=>"tn_$ARGV[0]")
    or die $resized->errstr;

__END__
