The ImagickDraw::setStrokeLineJoin() function is an inbuilt function in PHP which is used to specify the shape to be used at the corners of paths when they are stroked.
Syntax:
bool ImagickDraw::setStrokeLineJoin( $linejoin )
Parameters: This function accepts single parameter $linejoin which is used to hold the value of line join as integer type.
LINEJOIN constants:
- imagick::LINEJOIN_UNDEFINED (integer)
- imagick::LINEJOIN_MITER (integer)
- imagick::LINEJOIN_ROUND (integer)
- imagick::LINEJOIN_BEVEL (integer)
Return Value: This function does not return any value.
Below programs illustrate the ImagickDraw::setStrokeLineJoin() function in PHP:
Program 1:
<?php // require_once('path/vendor/autoload.php'); // Create an ImagickDraw object to draw into. $draw = new ImagickDraw(); // Set the stroke opacity $draw->setStrokeOpacity(1); // Set the stroke color $draw->setStrokeColor('Black'); // Set the stroke opacity $draw->setStrokeOpacity(0.8); //Set the stroke width $draw->setStrokeWidth(10); // Set Stroke Line Join Parameteres $draw->setStrokeLineJoin(Imagick::LINEJOIN_ROUND); // 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 dimension of 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 // Create an ImagickDraw object $draw = new ImagickDraw(); // Set the Stroke Width $draw->setStrokeWidth(1); // Set the Stroke Color $draw->setStrokeColor('black'); // Set the image filled color $draw->setFillColor('yellow'); // Set the Stroke Width $draw->setStrokeWidth(20); // Decalare the offset variable $offset = 220; $lineJoinStyle = [ Imagick::LINEJOIN_MITER, Imagick::LINEJOIN_ROUND, Imagick::LINEJOIN_BEVEL, ]; for ($x = 0; $x < count($lineJoinStyle); $x++) { $draw->setStrokeLineJoin($lineJoinStyle[$x]); $points = [ ['x' => 40 * 5, 'y' => 10 * 5 + $x * $offset], ['x' => 20 * 5, 'y' => 20 * 5 + $x * $offset], ['x' => 70 * 5, 'y' => 50 * 5 + $x * $offset], ['x' => 40 * 5, 'y' => 10 * 5 + $x * $offset], ]; // Draw the polygon $draw->polyline($points); } // Create new Imagick object $image = new Imagick(); // Set the image dimensions $image->newImage(500, 700, '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(); ?> |
