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


Output:

10

Program 2:




<?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();
?>
