Last Updated : 17 Dec, 2019

The ImagickDraw::getStrokeMiterLimit() function is an inbuilt function in PHP which is used to get the miter limit. When two line segments meet at a sharp angle, miter joins extend far beyond the thickness of the line stroking the path. Syntax:

int ImagickDraw::getStrokeMiterLimit( void )

Parameters: This function doesn’t accept any parameter. Return Value: This function returns an integer value containing the miter limit. Exceptions: This function throws ImagickException on error. Below given programs illustrate the ImagickDraw::getStrokeMiterLimit() function in PHP: Program 1:

php

<?php

// Create a new ImagickDraw object
$draw = new ImagickDraw();
  
// Get the stroke miter limit
$miterLimit = $draw->getStrokeMiterLimit();
echo $miterLimit;
?>

Output:

Program 2:

php

<?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');

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

// Set the stroke color
$draw->setStrokeColor('green');

// Set the stroke opacity
$draw->setStrokeOpacity(0.6);

// Set the fill color
$draw->setFillColor('white');

// Set the stroke width
$draw->setStrokeWidth(10);

// Set the stroke Line Join
$draw->setStrokeLineJoin(Imagick::LINEJOIN_MITER);

// Set the stroke miter limit
$draw->setStrokeMiterLimit(0);

// Create a polygon
$draw->polygon([
    ['x' => 100, 'y' => 60],
    ['x' => 60, 'y' => 80],
    ['x' => 400, 'y' => 100]
]);

// Set the font size
$draw->setFontSize(20);

// Decrease the stroke width so that text can be printed
$draw->setStrokeWidth(1);

// Print the text
$draw->annotation(450, 100, 'The strokeMiterLimit here is '
                             . $draw->getStrokeMiterLimit());

// Set the stroke width back to 10
$draw->setStrokeWidth(10);

// Set the stroke miter limit
$draw->setStrokeMiterLimit(40);

// Create a polygon
$draw->polygon([
    ['x' => 100, 'y' => 160],
    ['x' => 60, 'y' => 180],
    ['x' => 400, 'y' => 180]
]);

// Decrease the stroke width so that text can be printed
$draw->setStrokeWidth(1);

// Print the text
$draw->annotation(450, 180, 'The strokeMiterLimit here is ' 
                             . $draw->getStrokeMiterLimit());

// Render the draw commands
$imagick->drawImage($draw);

// Show the output
$imagick->setImageFormat('png');
header("Content-Type: image/png");
echo $imagick->getImageBlob();
?>
