note 114236 added to imagickdraw.circle

The four values required here are a bit confusing. After all, a circle is defined by three values: the x, y coordinates of the centre, and the radius, r. The fourth value is redundant, but has to be given, otherwise the function fails. One way of coping with this redundancy is: <?php $draw = new ImagickDraw (); //given that $x and $y are the coordinates of the centre, and $r the radius: $draw->circle ($x, $y, $x + $r, $y); ?> There are any number of actions which are synonymous with the last, including: <?php $draw->circle ($x, $y, $x, $y + $r); $draw->circle ($x, $y, $x - $r, $y); $draw->circle ($x, $y, $x, $y - $r); // etc, etc. ?> Hope this helps. ---- Server IP: 213.172.110.14 Probable Submitter: 89.182.69.28 ---- Manual Page -- http://php.net/manual/en/imagickdraw.circle.php Edit -- https://master.php.net/note/edit/114236 Del: integrated -- https://master.php.net/note/delete/114236/integrated Del: useless -- https://master.php.net/note/delete/114236/useless Del: bad code -- https://master.php.net/note/delete/114236/bad+code Del: spam -- https://master.php.net/note/delete/114236/spam Del: non-english -- https://master.php.net/note/delete/114236/non-english Del: in docs -- https://master.php.net/note/delete/114236/in+docs Del: other reasons-- https://master.php.net/note/delete/114236 Reject -- https://master.php.net/note/reject/114236 Search -- https://master.php.net/manage/user-notes.php
