For many (myself included) Rex's note maybe not be blatant enough. The constants are declared for the Imagick class only, so using them requires this syntax: Imagick::LINEJOIN_ constant



Here's an example oh how you might use it:



<?php

$img = new Imagick();

$img->newImage($width, $height, new ImagickPixel('transparent'));

$draw = new ImagickDraw();

$draw->setStrokeLineJoin(Imagick::LINEJOIN_ROUND);

?>



If you're not drawing polylines and are drawing simple lines, also see setStrokeLineCap
