How can I write this command line command in Perl using the ImageMagick API?

How can I do the same as the following command line command in Perl using the ImageMagick API? 

convert scotland.jpg[1x1+0+0] -depth 8 txt:

The result should look similar to this:

# ImageMagick pixel enumeration: 1,1,255,rgb
0,0: ( 48, 50, 47)  #30322F  rgb(48,50,47)

I found an explanation in Perl & Image::Magick, getting color values by pixel and lifted/changed the code. This works for me:

use strict; use warnings;
use Data::Dumper; 
use Image::Magick; 

my $img = Image::Magick->new; 
$img->Read("foo.jpg");

my @pixel = $img->GetPixels(
  width  => 1,
  height => 1,
  x      => 0,
  y      => 0,
  map    => "RGB"
);

print Dumper \@pixel;

As said by brian in his answer to the linked question, you may need to reduce the depth. See the other question for details.
