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
