Here is some code that does just what you want...it centres two lines of text, one a watermark and one a copyright message, over a GD::Image object $full. It should get you started: 

# Centre text components on image
my $colour    = $full->colorAllocate(0, 0, 0);
my @bounds    = new GD::Image->stringFT($colour, "Image/outline.ttf", 
+90, 0.18, 0, 0, $watermark_text); 
my $left       = ($full->width() / 2) - (($bounds[2] - $bounds[0]) / 2
+) + 5;
my $top        = ($full->height() / 2) - ($bounds[7] - $bounds[1]) / 2
+;
    
$full->stringFT($colour, "/Image/outline.ttf", 90, 0.18, $left, $top, 
+$watermark_text); 
@bounds        = new GD::Image->stringFT($colour, "Image/watermark.ttf
+", 95, 0.18, 0, 0, $copyright); 
$left       = ($full->width() / 2) - (($bounds[2] - $bounds[0]) / 2) +
+ 5;
$full->stringFT($colour, "Image/watermark.ttf", 95, 0.18, $left, $top 
++ 160, $copyright_text);
