note 78673 added to function.imagefilledpolygon

Just thought that 'tatlar at yahoo dot com's function has some redundant code in it, so I tried to "improve" it. Now you can choose a variable number of spikes. <?php error_reporting(E_ALL); function drawStar($x, $y, $radius, $spikes=5) { // $x, $y -> Position in the image // $radius -> Radius of the star // $spikes -> Number of spikes $coordinates = array(); $angel = 360 / $spikes ; // Get the coordinates of the outer shape of the star $outer_shape = array(); for($i=0; $i<$spikes; $i++){ $outer_shape[$i]['x'] = $x + ($radius * cos(deg2rad(270 - $angel*$i))); $outer_shape[$i]['y'] = $y + ($radius * sin(deg2rad(270 - $angel*$i))); } // Get the coordinates of the inner shape of the star $inner_shape = array(); for($i=0; $i<$spikes; $i++){ $inner_shape[$i]['x'] = $x + (0.5*$radius * cos(deg2rad(270-180 - $angel*$i))); $inner_shape[$i]['y'] = $y + (0.5*$radius * sin(deg2rad(270-180 - $angel*$i))); } // Bring the coordinates in the right order foreach($inner_shape as $key => $value){ if($key == (floor($spikes/2)+1)) break; $inner_shape[] = $value; unset($inner_shape[$key]); } // Reset the keys $i=0; foreach($inner_shape as $value){ $inner_shape[$i] = $value; $i++; } // "Merge" outer and inner shape foreach($outer_shape as $key => $value){ $coordinates[] = $outer_shape[$key]['x']; $coordinates[] = $outer_shape[$key]['y']; $coordinates[] = $inner_shape[$key]['x']; $coordinates[] = $inner_shape[$key]['y']; } // Return the coordinates return $coordinates ; } // Example $spikes = 5; $values = drawStar(250, 250, 200, $spikes); $im = imagecreate(500,500); imagecolorallocate($im,0,0,0); $w = imagecolorallocate($im, 255, 255, 255); imagefilledpolygon($im, $values, $spikes*2, $w); imageGIF($im); imagedestroy($im); ?> ---- Server IP: 217.13.201.10 Probable Submitter: 84.138.171.49 ---- Manual Page -- http://www.php.net/manual/en/function.imagefilledpolygon.php Edit -- https://master.php.net/note/edit/78673 Del: integrated -- https://master.php.net/note/delete/78673/integrated Del: useless -- https://master.php.net/note/delete/78673/useless Del: bad code -- https://master.php.net/note/delete/78673/bad+code Del: spam -- https://master.php.net/note/delete/78673/spam Del: non-english -- https://master.php.net/note/delete/78673/non-english Del: in docs -- https://master.php.net/note/delete/78673/in+docs Del: other reasons-- https://master.php.net/note/delete/78673 Reject -- https://master.php.net/note/reject/78673 Search -- https://master.php.net/manage/user-notes.php
