note 93088 added to function.imagettfbbox

I want to output a bounding box of a text as an image straightly. I did like this: <?php $text = "<?php echo \"hello, world\"; ?>"; $font = "./arial.ttf"; $size = "60"; $bbox = imagettfbbox($size, 0, $font, $text); $width = abs($bbox[2] - $bbox[0]); $height = abs($bbox[7] - $bbox[1]); $image = imagecreatetruecolor($width, $height); $bgcolor = imagecolorallocate($image, 255, 255, 255); $color = imagecolorallocate($image, 0, 0, 0); $x = $bbox[0] + ($width / 2) - ($bbox[4] / 2); $y = $bbox[1] + ($height / 2) - ($bbox[5] / 2); imagefilledrectangle($image, 0, 0, $width - 1, $height - 1, $bgcolor); imagettftext($image, $size, 0, $x, $y, $color, $font, $text); $last_pixel= imagecolorat($image, 0, 0); for ($j = 0; $j < $height; $j++) { for ($i = 0; $i < $width; $i++) { if (isset($blank_left) && $i >= $blank_left) { break; } if (imagecolorat($image, $i, $j) !== $last_pixel) { if (!isset($blank_top)) { $blank_top = $j; } $blank_left = $i; break; } $last_pixel = imagecolorat($image, $i, $j); } } $x -= $blank_left; $y -= $blank_top; imagefilledrectangle($image, 0, 0, $width - 1, $height - 1, $bgcolor); imagettftext($image, $size, 0, $x, $y, $color, $font, $text); header('Content-type: image/png'); imagepng($image); imagedestroy($image); ?> ---- Server IP: 140.112.2.5 Probable Submitter: 220.228.89.76 ---- Manual Page -- http://www.php.net/manual/en/function.imagettfbbox.php Edit -- https://master.php.net/note/edit/93088 Del: integrated -- https://master.php.net/note/delete/93088/integrated Del: useless -- https://master.php.net/note/delete/93088/useless Del: bad code -- https://master.php.net/note/delete/93088/bad+code Del: spam -- https://master.php.net/note/delete/93088/spam Del: non-english -- https://master.php.net/note/delete/93088/non-english Del: in docs -- https://master.php.net/note/delete/93088/in+docs Del: other reasons-- https://master.php.net/note/delete/93088 Reject -- https://master.php.net/note/reject/93088 Search -- https://master.php.net/manage/user-notes.php
