Example #1 ImagickDraw::setStrokeMiterLimit()

<?php
function setStrokeMiterLimit($strokeColor$fillColor$backgroundColor) {

    
$draw = new \ImagickDraw();

    
$draw->setStrokeColor($strokeColor);
    
$draw->setStrokeOpacity(0.6);
    
$draw->setFillColor($fillColor);
    
$draw->setStrokeWidth(10);

    
$yOffset 100;

    
$draw->setStrokeLineJoin(\Imagick::LINEJOIN_MITER);

    for (
$y 0$y 3$y++) {

        
$draw->setStrokeMiterLimit(40 $y);

        
$points = [
            [
'x' => 22 3'y' => 15 $y $yOffset],
            [
'x' => 20 3'y' => 20 $y $yOffset],
            [
'x' => 70 5'y' => 45 $y $yOffset],
        ];

        
$draw->polygon($points);
    }

    
$image = new \Imagick();
    
$image->newImage(500500$backgroundColor);
