note 75491 added to function.imagettfbbox

An improvement to the convertBoundingBox function. The previous function was completely wrong. My confusion came from characters like "1" and "_" that are rendered to the right or below the basepoint (in the font I'm using). I ended up using mike at mikeleigh dot com's function with a fix for these characters, and a "belowBasepoint" value. <?php function convertBoundingBox ($bbox) { if ($bbox[0] >= -1) $xOffset = -abs($bbox[0] + 1); else $xOffset = abs($bbox[0] + 2); $width = abs($bbox[2] - $bbox[0]); if ($bbox[0] < -1) $width = abs($bbox[2]) + abs($bbox[0]) - 1; $yOffset = abs($bbox[5] + 1); if ($bbox[5] >= -1) $yOffset = -$yOffset; // Fixed characters below the baseline. $height = abs($bbox[7]) - abs($bbox[1]); if ($bbox[3] > 0) $height = abs($bbox[7] - $bbox[1]) - 1; return array( 'width' => $width, 'height' => $height, 'xOffset' => $xOffset, // Using xCoord + xOffset with imagettftext puts the left most pixel of the text at xCoord. 'yOffset' => $yOffset, // Using yCoord + yOffset with imagettftext puts the top most pixel of the text at yCoord. 'belowBasepoint' => max(0, $bbox[1]) ); } ?> ---- Server IP: 64.71.164.2 Probable Submitter: 67.161.110.125 ---- Manual Page -- http://www.php.net/manual/en/function.imagettfbbox.php Edit -- https://master.php.net/note/edit/75491 Del: integrated -- https://master.php.net/note/delete/75491/integrated Del: useless -- https://master.php.net/note/delete/75491/useless Del: bad code -- https://master.php.net/note/delete/75491/bad+code Del: spam -- https://master.php.net/note/delete/75491/spam Del: non-english -- https://master.php.net/note/delete/75491/non-english Del: in docs -- https://master.php.net/note/delete/75491/in+docs Del: other reasons-- https://master.php.net/note/delete/75491 Reject -- https://master.php.net/note/reject/75491 Search -- https://master.php.net/manage/user-notes.php
