Below programs illustrate the ImagickDraw::getStrokeLineJoin() function in PHP:

Program 1:

<?php

// Create a new ImagickDraw object

$draw = new ImagickDraw();

// Set the stroke line join
$draw->setStrokeLineJoin(3);

// Get the stroke line join
$lineJoin = $draw->getStrokeLineJoin();
echo $lineJoin;
?>

Output:

3 // Which corresponds to imagick::LINEJOIN_BEVEL

Program 3:

<?php

// Create a new ImagickDraw object
$draw = new ImagickDraw();

// Create a new imagick object
$imagick = new Imagick();

// Create a image on imagick object
$imagick->newImage(800, 250, 'white');

// Set the stroke line join
$draw->setStrokeLineJoin(2);

// Draw a rectangle
$draw->rectangle(500, 50, 625, 175);

// Annotate a text
$draw->annotation(400, 220, 'The strokeLineJoin here is '
        . $draw->getStrokeLineJoin());

// Render the draw commands
