    From imagick_helpers.c (pecl release), possible values are:
      LINEJOIN_UNDEFINED
      LINEJOIN_MITER
      LINEJOIN_ROUND
      LINEJOIN_BEVEL

    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
