Previous Comments: ------------------------------------------------------------------------ [2021-07-30 18:00:01] chzhdy at live dot com Description: ------------ When the size of ellipse is larger than about 2200px, imagefilledellipse() will start to draw a strange shape. It seems that the problem only happens to "PHP for Windows", because the script works well on my Ubuntu Server. [PHP Version] PHP 8.0 (8.0.9) for Windows - VS16 x64 Non Thread Safe (2021-Jul-29 14:38:16) Test script: --------------- $w = 3000; $h = 3000; $im = imagecreatetruecolor($w, $h); $color = imagecolorallocate($im, 0, 124, 255); imagefilledellipse($im, $w / 2, $h / 2, $w, $h, $color); header('content-type: image/png'); imagepng($im); Expected result: ---------------- imagefilledellipse() can draw an ellipse while the size is large. Actual result: -------------- imagefilledellipse() draws a strange shape. ------------------------------------------------------------------------ -- Edit this bug report at https://bugs.php.net/bug.php?id=81315&edit=1
