PHP | ImagickDraw setStrokeMiterLimit() Function

Last Updated : 30 Aug, 2019

The ImagickDraw::setStrokeMiterLimit() function is an inbuilt function in PHP which is used to specify the miter limit of stroke. When two line segments are meet at a sharp angle and miter joins have been specified for 'lineJoin', it is possible for the miter to extend far beyond the thickness of the line stroking the path. The miterLimit' imposes a limit on the ratio of the miter length to the 'lineWidth'. Syntax:

bool ImagickDraw::setStrokeMiterLimit( $miterlimit )

Parameters: This function accepts a single parameter $miterlimit which is used to hold the value of miter limit as integer type. Return Value: This function does not return any value. Below programs illustrate the ImagickDraw::setStrokeMiterLimit() function in PHP: Program 1:

php

<?php

// require_once('path/vendor/autoload.php');

// Create an ImagickDraw object
$draw = new \ImagickDraw();

// Set the Stroke Opacity
$draw->setStrokeOpacity(1);

// Set the Stroke Color
$draw->setStrokeColor('Black');

// Set the Stroke Opacity
$draw->setStrokeOpacity(0.6);

// Set the Stroke Width  
$draw->setStrokeWidth(4);

// Set the image filled color 
$draw->setFillColor('lightgreen');
    
// Set the Stroke Miter Limit 
$draw->setStrokeMiterLimit(40 * 12);
$points = [
        ['x' => 50 * 6, 'y' => 10 * 5],
        ['x' => 20 * 7, 'y' => 30 * 5], 
        ['x' => 60 * 8, 'y' => 50 * 5], 
        ['x' => 70 * 3, 'y' => 15 * 5],
    ];

// Draw the polygon 
$draw->polygon($points);

// Create new Imagick object 
$image = new \Imagick();

// Set the dimensions of the image
$image->newImage(500, 300, 'white');

// Set the image format
$image->setImageFormat("png");

// Draw the image
$image->drawImage($draw);
header("Content-Type: image/png");

// Display the Image
echo $image->getImageBlob();
?>

Output:

Program 2:

php

<?php
 
// require_once('path/vendor/autoload.php');
 
// Create a ImagickDraw object to draw into.
$draw = new ImagickDraw();
 
// Set the Stroke Width
$draw->setStrokeWidth(5);
 
// Set the Stroke Miter Limit
$draw->setStrokeMiterLimit(50 * 15);
 
// Set the Stroke Color
$draw->setStrokeColor('black');
 
// Set the image filled color
$draw->setFillColor('red');
$points = [['x' => 40 * 5, 'y' => 10 * 5],

          ['x' => 60 * 5, 'y' => 15 * 5], ];
 
// Draw the polygon 
$draw->polygon($points);
 
// Set the image filled color
$draw->setFillColor('green');
 
// Set the translation points
$draw->translate(10, 30);
$points = [['x' => 40 * 5, 'y' => 10 * 5],
           ['x' => 70 * 5, 'y' => 50 * 5], 
           ['x' => 60 * 5, 'y' => 15 * 5], ];
