    Przykład #1 ImagickDraw::setStrokeLineJoin()

    <?php
    function setStrokeLineJoin($strokeColor, $fillColor, $backgroundColor) {

            $draw = new \ImagickDraw();
            $draw->setStrokeWidth(1);
            $draw->setStrokeColor($strokeColor);
            $draw->setFillColor($fillColor);

            $draw->setStrokeWidth(20);

            $offset = 220;

            $lineJoinStyle = [
            \    Imagick::LINEJOIN_MITER,
            \    Imagick::LINEJOIN_ROUND,
            \    Imagick::LINEJOIN_BEVEL,
            ];

        for (    $x = 0; $x < count($lineJoinStyle); $x++) {
                $draw->setStrokeLineJoin($lineJoinStyle[$x]);
                $points = [
                [    'x' => 40 * 5, 'y' => 10 * 5 + $x * $offset],
                [    'x' => 20 * 5, 'y' => 20 * 5 + $x * $offset],
                [    'x' => 70 * 5, 'y' => 50 * 5 + $x * $offset],
                [    'x' => 40 * 5, 'y' => 10 * 5 + $x * $offset],
            ];

        }

            $image = new \Imagick();
            $image->newImage(500, 700, $backgroundColor);

      LINEJOIN_UNDEFINED
      LINEJOIN_MITER

    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
