note 75333 added to function.imagettfbbox

Ralph Bolton commented about the difference in calculating the bounding box size vs. aligning text base line. The workaround for this issue is to calculate the difference in height between a character going below baseline and one above the baseline. This is likely going to vary from font to font, so I'd suggest something like this: <?php function fontBaselineOffset($font, $fontSize) { //this should be above baseline $test2="H"; //some of these additional letters should go below it $test3="Hjgqp"; //get the dimension for these two: $box2 = imageTTFBbox($fontSize,0,$font,$test2); $box3 = imageTTFBbox($fontSize,0,$font,$test3); //return the offset value return abs((abs($box2[5]) + abs($box2[1])) - (abs($box3[5]) + abs($box3[1]))); } ?> This is not perfect yet. You should define a range of allowed characters that can go below baseline, compare them to the ones actually found in your string and use them instead of the string $test3 used in the example function above. This should avoid problems with letters that go further below baseline than the others (e.g. there could be a difference between 'g' and 'p') ---- Server IP: 62.237.7.3 Probable Submitter: 128.214.215.13 ---- Manual Page -- http://www.php.net/manual/en/function.imagettfbbox.php Edit -- https://master.php.net/note/edit/75333 Del: integrated -- https://master.php.net/note/delete/75333/integrated Del: useless -- https://master.php.net/note/delete/75333/useless Del: bad code -- https://master.php.net/note/delete/75333/bad+code Del: spam -- https://master.php.net/note/delete/75333/spam Del: non-english -- https://master.php.net/note/delete/75333/non-english Del: in docs -- https://master.php.net/note/delete/75333/in+docs Del: other reasons-- https://master.php.net/note/delete/75333 Reject -- https://master.php.net/note/reject/75333 Search -- https://master.php.net/manage/user-notes.php
