note 83248 added to function.imagettftext

If you're looking for easy text alignment, you need to use the imagettfbbox() command. When given the correct parameters, it will return the boundaries of your to-be-made text field in an array, which will allow you to calculate the x and y coordinate that you need to use for centering or aligning your text. A horizontal centering example: <?php $tb = imagettfbbox(17, 0, 'airlock.ttf', 'Hello world!'); ?> $tb would contain: Array ( [0] => 0 // lower left X coordinate [1] => -1 // lower left Y coordinate [2] => 198 // lower right X coordinate [3] => -1 // lower right Y coordinate [4] => 198 // upper right X coordinate [5] => -20 // upper right Y coordinate [6] => 0 // upper left X coordinate [7] => -20 // upper left Y coordinate ) For horizontal alignment, we need to substract the "text box's" width { $tb[2] or $tb[4] } from the image's width and then substract by two. Saying you have a 200px wide image, you could do something like this: <?php $x = ceil((200 - $tb[2]) / 2); // lower left X coordinate for text imagettftext($im, 17, 0, $x, $y, $tc, 'airlock.ttf', 'Hello world!'); // write text to image ?> This'll give you perfect horizontal center alignment for your text, give or take 1 pixel.
