note 17231 added to function.imagearc

I found a better way for drawing a pie chart: header ("Content-type: image/png"); $diameter = 100; $radius = $diameter / 2; $centerX = $radius; $centerY = $radius; $im = @ImageCreate ($diameter, $diameter) or die ("Cannot Initialize new GD image stream"); $background = ImageColorAllocate ($im, 0, 0, 0); $red = ImageColorAllocate ($im, 176, 0, 0); function fill_arc($start, $end, $color) { global $diameter, $centerX, $centerY, $im, $radius; imagearc($im, $centerX, $centerY, $diameter, $diameter, $start, $end, $color); imageline($im, $centerX, $centerY, $centerX + cos(deg2rad($start)) * $radius, $centerY + sin(deg2rad($start)) * $radius, $color); imageline($im, $centerX, $centerY, $centerX + cos(deg2rad($end)) * $radius, $centerY + sin(deg2rad($end)) * $radius, $color); imagefill ($im,$centerX + $radius * 0.5 *cos(deg2rad($start+($end-$start)/2)), $centerY + $radius * 0.5 * sin(deg2rad($start+($end-$start)/2)), $color); } fill_arc(0,30,$red); // Will make a red filled arc, starting at 0 degrees, ending at 30 degrees ImagePng ($im); -- http://www.php.net/manual/en/function.imagearc.php http://master.php.net/manage/user-notes.php?action=edit+17231 http://master.php.net/manage/user-notes.php?action=delete+17231 http://master.php.net/manage/user-notes.php?action=reject+17231
