my @cords = GD::Image->stringTTF(0, $font_path, $size, 0, 0, 0, $text)

If I'm not mistaken, that puts the method call in a scalar context (you used ||), so the @cords variable is always going to be a single values that is whatever that method call does in a scalar context.

I think you want: 


(my @cords = GD::Image->stringTTF(0, $font_path, $size, 0, 0, 0, $text
+)) || die "no cords $! $@";

which will die if an empty list is returned. (I don't know that interface, so I'm not sure if that's the way it indicates errors.)

Or, without the annoying parens: 

my @cords = GD::Image->stringTTF(0, $font_path, $size, 0, 0, 0, $text)
  or die "no cords $! $@";

[download]
which I would prefer, including the hanging indent on the next line.
