You'll see that get_dip is returned in $dip which is called by ImageCreatetruecolor where it is subtracted from the $box[5] value. If you're motivated to try, you should be able to override the $dip value received by get_dip() by increasing or decreasing $dip based on the desired output per font implementation.

?PHP
// create image
$font_rgba = extract_color($font_color);
$dip = get_dip($font_file,$font_size);
$box = @ImageTTFBBox($font_size,0,$font_file,$text);
$image = @ImageCreatetruecolor(abs($box[2]-$box[0])+1,abs($box[5]-$dip));
if(!$image || !$box) {
fatal_error('Error: The server could not create this heading image.');
}

You’ll see that get_dip is returned in $dip which is called by ImageCreatetruecolor where it is subtracted from the $box[5] value. If you’re motivated to try, you should be able to override the $dip value received by get_dip() by increasing or decreasing $dip based on the desired output per font implementation.

?PHP
// create image
$font_rgba = extract_color($font_color);
$dip = get_dip($font_file,$font_size);
$box = @ImageTTFBBox($font_size,0,$font_file,$text);
$image = @ImageCreatetruecolor(abs($box[2]-$box[0])+1,abs($box[5]-$dip));
if(!$image || !$box) {
fatal_error(‘Error: The server could not create this heading image.’);
}

Any way that can be fixed? Cool plugin, but it seems to cut off the images from the bottom. Any way that can be fixed?
