note 116846 added to function.sqrt

As we all know, the square of the hypotenuse is equal to the sum of the squares of the other two sides of a right triangle (a2 + b2 = c2). With that in mind I created a quick way to reduce images to a maximum area without messing up width/height constraints. <?php list($width_orig, $height_orig) = getimagesize($img); $max_a = 500000; // maximum area in pixels $width = $width_orig; $height = $height_orig; $area = $width * $height; if ($area > $max_a) { $mult = sqrt($max_a) / sqrt($height * $width); $width *= $mult; $height *= $mult; } ?> ---- Server IP: 72.52.91.14 Probable Submitter: 110.148.168.237 ---- Manual Page -- http://php.net/manual/en/function.sqrt.php Edit -- https://master.php.net/note/edit/116846 Del: integrated -- https://master.php.net/note/delete/116846/integrated Del: useless -- https://master.php.net/note/delete/116846/useless Del: bad code -- https://master.php.net/note/delete/116846/bad+code Del: spam -- https://master.php.net/note/delete/116846/spam Del: non-english -- https://master.php.net/note/delete/116846/non-english Del: in docs -- https://master.php.net/note/delete/116846/in+docs Del: other reasons-- https://master.php.net/note/delete/116846 Reject -- https://master.php.net/note/reject/116846 Search -- https://master.php.net/manage/user-notes.php
