Previous Comments: ------------------------------------------------------------------------ [2003-02-06 22:18:03] ljpersson@hotmail.com (Using built-in GD 2.x in PHP 4.3.0) imagefilledellipse() creates moire' patterns inside the filled ellipse when alpha blending is enabled. The problem seems to be that the fill algorithm strokes the same point within the ellipse several times and due to the alpha blending of single pixels creates several color shades within the ellipse. This is fine as long as a solid fill is used but does not work together with alpha blending. ------------------------------------------------------------------------ -- Edit this bug report at http://bugs.php.net/?id=22103&edit=1
